Definitions

  • Powder raw material and liquid raw material mixing apparatus and method for producing a mixture using the mixing apparatus
  • the present invention relates to a continuous mixing technique of a powder raw material and a liquid raw material.
  • the ideal final state of mixing is that each flour particle retains moisture at an even rate.
  • several phenomena have occurred in the process of mixing, preventing the ideal state from being reached.
  • One of the inhibiting factors is a phenomenon in which water does not easily penetrate into flour.
  • Flour particles have a strong affinity with air. Therefore, mixing does not occur easily because the air surrounding the flour particles prevents the water and flour particles from approaching. In this phenomenon, even if water is poured into a container containing flour and left for a while, the mixing of the two does not proceed! / You will also realize by observing the child.
  • Another phenomenon that hinders the reaction is the change of the state of flour by the reaction of flour and water. Assume that the required amount of moisture has been given to the flour particles. Then, gliadin and glutenin, which are the main components of the protein contained in wheat flour at 6% to 15%, react with water. As a result, a protein called dulten that has both stickiness and elasticity is produced.
  • the above numerical value (ratio of the weight of water to wheat flour) is referred to as a water addition rate.
  • the reason for lowering the water content at the time of koji making is to prevent the dough from sticking to a koji roll for forming koji.
  • the dough for koji has problems such as the destruction of the dartene structure and the disappearance of the so-called “koshi” immediately after the bread dough is made.
  • Patent Document 1 As another mixing technique, there is a “continuous high-speed stirring and mixing mixer” (Patent Document 1). When mixing flour and water with this device, water atomized by the action of a paddle rotating in the casing comes into contact with the flour that flows in the axial direction while rotating, and continues to bow. Kneading is performed downstream. [0020] However, since water has a structure in which water is injected at a single location outside the casing with a water pipe, there is no guarantee that a uniform dough will be produced at the first contact between water and flour. In order to cover this, a kneading process is provided in the subsequent stage to achieve a certain level of uniformity, but this is insufficient.
  • the kneading also destroys the network structure of Dalten, and is discharged out of the apparatus with poor quality.
  • the mixture becomes a so-called rag and can be used as it is as a dough for baking or baking!
  • Patent Document 2 a thin film is supplied that is quantitatively supplied to the center of a rotating disk and flows radially onto the disk surface after contact with the disk, and the inner surface of the cylindrical wall drops onto the disk due to overflow.
  • a mixing device that is brought into contact with a liquid to obtain a continuous mixture.
  • the mixture discharged from the mixing device has a so-called rag shape in which dough with insufficient moisture surrounds dough with excess moisture. Therefore, the raw dough cannot be used for bread making or koji making.
  • Patent Document 3 “Method of hydrolysis and maturation in the production of wheat flour kneaded products” aims at bringing flour and water into a fine particle state and bringing them into direct contact with each other.
  • Patent Document 3 prevents re-spraying onto particles that have been combined with fine water droplets. Therefore, it is difficult to achieve uniform mixing as intended without a mechanism for selectively spraying particles with delayed bonding. It is the same in that it is difficult to expect a sufficient effect in other examples in Patent Document 3. In other words, the specific method of ideal blending that we are aiming for is presented as a fool.
  • the problem of the prior art in mixing powder and liquid is the problem to be solved by the present invention.
  • the fundamental problem of the prior art is that in order to achieve complete mixing, it is necessary to knead after mixing V, just.
  • the present invention aims to provide a method for realizing complete mixing without a kneading step.
  • the reaction between the two products generated after mixing is an important substance, such as the mixing of flour and water.
  • the importance of the subject of the present invention is extremely large.

Abstract

A powdery material is fed at a definite rate to the center of a disc, which is rotating at a moderate speed, to form a thin powder layer close to the periphery of the disc. On the other hand, a sprayer rotating at thigh speed is provided on the same axis as the rotating disc and a liquid material, which is fed at a definite rate, is continuously sprayed and radiated thereby. Thus, the liquid material is sprayed at a high speed from behind to the powder layer flow having been spread on the rotating disk. As a result, a homogeneous and instantaneous bond is continuously formed at the micro level between these materials so that a homogeneous mixture of the powdery material with the liquid material can be continuously obtained. By homogeneously mixing the powdery material with the liquid material from the beginning, agitation becomes unnecessary, which makes it possible to prevent the mixture from denaturation in the qualities thereof. Moreover, it becomes possible to remarkably shorten the process and simplify the apparatus. In the case of using in mixing a powder material mainly comprising wheat flour with a liquid material mainly comprising water, in particular, the apparatus or the method as described above makes it possible to produce bread or noodles with excellent qualities by a shortened and simplified process.

粉体原料と液体原料の混合装置、及びその混合装置を用いた混合物の 製造方法  Powder raw material and liquid raw material mixing apparatus, and method for producing a mixture using the mixing apparatus
技術分野  Technical field
[0001] 本発明は、粉体原料と液体原料の連続混合技術に関する。  [0001] The present invention relates to a continuous mixing technique of a powder raw material and a liquid raw material.
背景技術  Background art
[0002] 食品、化学、電子など様々な産業にぉ 、て、粉体原料と液体原料を連続して混合 するための装置が用いられて 、る。  In various industries such as food, chemistry, and electronics, apparatuses for continuously mixing powder raw materials and liquid raw materials are used.
例えば製パン工程にぉ ヽて小麦粉と水を混合する場合、混合の理想的な最終状 態は各小麦粉粒子が均等な割合で水分を抱くことである。ところが、従来、混合が進 行する過程で、いくつかの現象が生じ、理想状態への到達を妨げている。  For example, when mixing flour and water during the bread-making process, the ideal final state of mixing is that each flour particle retains moisture at an even rate. However, in the past, several phenomena have occurred in the process of mixing, preventing the ideal state from being reached.
[0003] その阻害要因となる現象の 1つは、小麦粉への水の浸透が生じにくい現象である。  [0003] One of the inhibiting factors is a phenomenon in which water does not easily penetrate into flour.
小麦粉粒子は、空気との親和性が強い。そのため、小麦粉粒子を取り囲んだ空気が 水と小麦粉粒子との接近を妨害するため、混合は容易には生じなくなる。この現象は 小麦粉を入れた容器に水を注 、で暫く放置しても、両者の混合が一向に進まな!/ヽ様 子を観察することでも実感されよう。  Flour particles have a strong affinity with air. Therefore, mixing does not occur easily because the air surrounding the flour particles prevents the water and flour particles from approaching. In this phenomenon, even if water is poured into a container containing flour and left for a while, the mixing of the two does not proceed! / You will also realize by observing the child.
[0004] もう 1つの阻害要因となる現象は、小麦粉と水とが反応して小麦粉の状態が変化す ることである。必要量の水分を小麦粉粒子に与えたと仮定する。そうすると、小麦粉中 に 6%〜 15%含まれている蛋白質の主成分であるグリアジンとグルテニン(両者はほ ぼ同量含まれている)とが水と反応する。その結果、粘着性と弾力性を併せ持つダル テンという蛋白質が生成される。  [0004] Another phenomenon that hinders the reaction is the change of the state of flour by the reaction of flour and water. Assume that the required amount of moisture has been given to the flour particles. Then, gliadin and glutenin, which are the main components of the protein contained in wheat flour at 6% to 15%, react with water. As a result, a protein called dulten that has both stickiness and elasticity is produced.
[0005] そのダルテンに練りをカ卩えると、網目状の組織が作られる。実はダルテンの網目組 織は、イースト菌による発酵が進む際に発生した炭酸ガスの気泡を閉じ込めることで 、パンを膨らませるという重要な役割を担っている。  [0005] When a kneading is applied to the Dalten, a network structure is formed. In fact, Darten's mesh structure plays an important role in expanding bread by confining the bubbles of carbon dioxide generated during fermentation by yeast.
[0006] これらの現象を念頭に置きながら、ミキシングの時間経過と共に生じる状態変化を 考察する。まず、小麦粉と水 (実際は食塩やイースト菌などの水溶液)とを容器に入 れると、小麦粉への水の浸透が始まる。し力しながら、その浸透速度は極めて緩慢で 、そのまま放置しても両者の混合は遅々として進まない。 [0006] With these phenomena in mind, let us consider state changes that occur over time of mixing. First, when flour and water (actually, an aqueous solution of salt, yeast, etc.) are placed in the container, water penetration into the flour begins. However, the penetration rate is very slow. Even if it is left as it is, mixing of both does not proceed slowly.
[0007] 小麦粉と水を均一に混合するためには、繰り返しの塑性流動を隈なく加える操作、 すなわち攪拌混合を行う必要がある。前述のように、水の浸透が緩慢であるため、攪 拌を行っても小麦粉粒子への水分の浸透結合、すなわち水和は一気には進まな 、。 水和は混合物内の所々の部分から全体へ徐々に拡張進行するので、生地全体に水 が行き渡るまで攪拌混合を続けなければならない。  [0007] In order to uniformly mix the flour and water, it is necessary to perform an operation of thoroughly adding a plastic flow, that is, stirring and mixing. As mentioned above, the water penetration is slow, so even if agitation is carried out, the osmotic bond of moisture to the flour particles, that is, hydration does not proceed at once. Hydration gradually expands from place to place throughout the mixture, so stirring and mixing must continue until water has spread throughout the dough.
[0008] 水和の先行した所々の部分ではダルテンが生成され、それに捏ねが加わることで 網目組織が作られる。その組織は前述のように重要なものであるが、一度破壊される と再生されな 、と 、う厄介な性質を持つ。  [0008] In some places where hydration precedes, dartene is generated and a kneading is added to create a network. The organization is important as mentioned above, but it has the troublesome nature that once destroyed, it cannot be regenerated.
[0009] ところが、不都合なことに攪拌混合による強 、捏ね作用は、ダルテンの網目組織に 破壊作用をもたらすのである。この破壊作用は、攪拌混合が完了するまで続く。すな わち、従来の機械的ミキシング工程では、(i)生地全体への水分の浸透、(ii)捏ね作 用をカ卩えることによるダルテンの網目組織の生成、(m)過剰な捏ねによるダルテンの 網目組織の破壊、の 3つの現象が同時に生じる。このために、緻密なダルテン組織を 生地全体に生成させることは困難であった。  [0009] However, unfortunately, the strong and kneading action caused by stirring and mixing has a destructive action on the network structure of Dalten. This breaking action continues until stirring and mixing are complete. In other words, in the conventional mechanical mixing process, (i) moisture penetration throughout the dough, (ii) formation of a dartene network by covering kneading, and (m) due to excessive kneading. Three phenomena occur simultaneously: the destruction of the Darten network. For this reason, it was difficult to produce a dense dartene structure throughout the dough.
[0010] そこで、品質を重視する製パン業者は、時間や手間やコストを犠牲にしてパン生地 を製造している。例えば、機械による捏ねを混合不足の段階で止めてダルテン組織 の破壊を抑えている。さらに、イースト菌の異常発酵を抑えるために生地の"寝力せ" を冷蔵庫中で長時間行い、水の自然な拡散浸透を図っている。あるいは少量生産の 場合は手で長時間丁寧に捏ねて生地を作っている。  [0010] Therefore, breadmakers who place importance on quality produce bread dough at the expense of time, labor and cost. For example, the kneading by the machine is stopped at the stage of insufficient mixing to prevent the destruction of the dartene structure. Furthermore, in order to suppress the abnormal fermentation of yeast, the dough is "sleeped" for a long time in the refrigerator to allow natural diffusion and penetration of water. Or for small-scale production, dough is kneaded carefully by hand for a long time.
[ooi i] し力しながら、このような努力しても、(i)〜(m)の 3つの現象の同時進行を完全に避 けることにはならない。従来技術では、加水不足のためにダルテンが生成されない部 分と、ダルテンの網目組織が破壊された部分とが、多くの箇所で存在する生地しか得 ることができないのである。 [ooi i] However, even if such efforts are made, the simultaneous progress of the three phenomena (i) to (m) is not completely avoided. In the prior art, it is only possible to obtain a dough in which dartene is not generated due to lack of water and where the dartene network structure is destroyed in many places.
[0012] 製パン業者の中には、ダルテンの強化を行うために敢えて発癌性物質である臭素 酸カリウムを添加物として使用するメーカーさえある。すなわち従来の製パン方法で は品質、経済性、安全性などで多くの解決困難な問題を抱えているのである。  [0012] Some bakers even use the carcinogen, potassium bromate, as an additive to strengthen the dartene. In other words, the conventional bread making methods have many difficult problems to solve in terms of quality, economy and safety.
[0013] 製麵用のドウ(DOUGH)作りについて述べると、従来の方法では生地全体への水 の完全な浸透という点では製パン以上の困難がある。 [0013] Regarding the making of DOUGH for slag making, the conventional method uses water to the entire dough. This is more difficult than bread making in terms of complete penetration.
すなわち、製パンの場合は小麦粉を 100とした場合、重量比で水の量は 60〜65で あるのに対し、製麵では 30〜50である。したがって、製麵の場合は、水を小麦粉全 体に満遍なく行き渡らせることはパン生地以上に難しいのである。  That is, in the case of breadmaking, when the flour is 100, the amount of water is 60-65 by weight, whereas in the case of koji making, it is 30-50. Therefore, in the case of koji making, it is more difficult to distribute water throughout the flour than bread dough.
[0014] なお、上記の数値 (小麦粉に対する水の重量の比率)は、加水率と呼ばれる。製麵 時に加水率を低くする理由は、麵を形作るための製麵ロールなどに生地が粘着する ことを防ぐことにある。 [0014] Note that the above numerical value (ratio of the weight of water to wheat flour) is referred to as a water addition rate. The reason for lowering the water content at the time of koji making is to prevent the dough from sticking to a koji roll for forming koji.
[0015] 従って、機械的ミキシングを十分に行おうとすると、生地が硬いゆえに生地を塑性 流動させるために加える力が増え、生地内に発生する応力も大きくなる。従って、製 麵用生地はパン生地作成時以上にダルテン組織の破壊が生じやすぐいわゆる"こ し"がなくなるなどの問題が生じる。  [0015] Therefore, if sufficient mechanical mixing is performed, the force applied to plastically flow the dough increases because the dough is hard, and the stress generated in the dough also increases. Accordingly, the dough for koji has problems such as the destruction of the dartene structure and the disappearance of the so-called “koshi” immediately after the bread dough is made.
[0016] また、ダルテン組織の破壊を避けるためにミキシング時間を短縮すると、水分の均 一化が不足する。水の不足箇所ではダルテンの生成不足が生じ、水の過剰な箇所 では製麵ロール等への粘着性が生じてしまう。その結果、高品質な麵作りが阻害され る。  [0016] Further, if the mixing time is shortened in order to avoid the destruction of the dartene structure, moisture uniformity is insufficient. In areas where water is insufficient, dartene formation is inadequate, and in areas where water is excessive, stickiness to a steelmaking roll or the like occurs. As a result, high-quality koji making is impeded.
[0017] 要するに、粘着防止のために加水率を減らすと、攪拌混合によるダルテン組織の破 壊が増えてしまう。一方、攪拌混合を控えれば、水分過剰な部分では粘着の増加で 加工に支障を来たし、不足箇所ではダルテン生成が不足してしまう。このように、加水 率の増減及び攪拌時間は、二律背反的な問題を抱えて 、るのである。  In short, if the water content is reduced to prevent sticking, the destruction of the dartene structure due to stirring and mixing increases. On the other hand, if stirring and mixing are refrained, processing will be hindered due to increased adhesion in areas with excessive moisture, and dartene generation will be insufficient in areas where there is insufficient water. As described above, the increase / decrease in the hydrolysis rate and the stirring time have a trade-off problem.
[0018] 高級な麵類の製造では、その二律背反的な問題の対策として、ある程度ミキシング を行った後に生地の寝力 を行って水分の自然な拡散を待つ方法がある。しかしな がら、水分の分布の完全均一化を期すことは難しい。また、製造工程の冗長化や製 造コストの増加を余儀なくされる。最高級品質を目指す場合は手捏ねを行うが、高度 の技能や多大な労力が必要になり、当然高価なものになる。  [0018] In the manufacture of high-grade moss, there is a method of waiting for the natural diffusion of moisture by performing the bed rest of the dough after mixing to some extent as a countermeasure against the contradictory problem. However, it is difficult to achieve a uniform distribution of moisture. In addition, manufacturing process redundancy and manufacturing costs are inevitably increased. When aiming for the highest quality, it is necessary to do the work, but it requires a high level of skill and a lot of labor, and it is naturally expensive.
[0019] その他の混合技術として、「連続型高速攪拌混合ミキサー」がある (特許文献 1)。こ の装置で小麦粉と水のミキシングを行う場合、ケーシング中にて回転するパドルの作 用で微粒子化された水は、回転しながら軸方向に流れる小麦粉と接触して結合し、 弓 Iき続き下流にて混練を行う。 [0020] し力しながら、水はケーシングの外側の一箇所力も水管で注入される構造であるた め、水と小麦粉との始めの接触時において均一な生地が生成される保証はない。そ れをカバーするために後段に混練工程を設けて、ある程度均一化を図っては ヽるが 不十分である。さらに、混練によってダルテンの網目組織の破壊も生じてしまい、品 質が悪いまま装置外へ排出される。その結果、混合物はいわゆるそぼろ状になり、そ のままでは製パンまたは製麵用の生地として使えな!/、。 [0019] As another mixing technique, there is a "continuous high-speed stirring and mixing mixer" (Patent Document 1). When mixing flour and water with this device, water atomized by the action of a paddle rotating in the casing comes into contact with the flour that flows in the axial direction while rotating, and continues to bow. Kneading is performed downstream. [0020] However, since water has a structure in which water is injected at a single location outside the casing with a water pipe, there is no guarantee that a uniform dough will be produced at the first contact between water and flour. In order to cover this, a kneading process is provided in the subsequent stage to achieve a certain level of uniformity, but this is insufficient. In addition, the kneading also destroys the network structure of Dalten, and is discharged out of the apparatus with poor quality. As a result, the mixture becomes a so-called rag and can be used as it is as a dough for baking or baking!
[0021] 特許文献 2では、回転円盤上の中心に定量供給され、円盤との接触後に円盤表面 に放射状に流れる粉体を、オーバーフローによって円筒状の壁の内面を円盤上に落 下する薄膜の液体と接触させて、連続的に混合物を得る混合装置が開示されている  [0021] In Patent Document 2, a thin film is supplied that is quantitatively supplied to the center of a rotating disk and flows radially onto the disk surface after contact with the disk, and the inner surface of the cylindrical wall drops onto the disk due to overflow. Disclosed is a mixing device that is brought into contact with a liquid to obtain a continuous mixture.
[0022] しかしながら、特許文献 2の方法を小麦粉と水との混合に用いる場合、薄膜とは言 え液体膜の厚みは小麦粉粒子径と比較すると桁違いに大きいので、個々の小麦粉 粒子に対し均一に液体を結合させることはできない。 [0022] However, when the method of Patent Document 2 is used for mixing flour and water, the thickness of the liquid film, even though it is a thin film, is an order of magnitude larger than the particle size of the flour, so it is uniform for each flour particle. Liquid cannot be bound to
[0023] 特許文献 2の方法にぉ 、て、小麦粉と水の接触直後では混合状態が不完全である[0023] According to the method of Patent Document 2, the mixing state is incomplete immediately after the contact of flour and water.
。そこで、特許文献 1と同様に、同じ装置内の下流の箇所に設けた混練室で攪拌混 合を行って均質ィ匕を図って 、る。 . Therefore, as in Patent Document 1, stirring and mixing are performed in a kneading chamber provided at a downstream location in the same apparatus to achieve homogeneity.
[0024] ところが、いったん生じた混合物の不均一状態の解消はやはり困難である。混合装 置から排出された混合物は、過剰な水分を抱く生地を水分不足の生地が取り囲んで いる、いわゆるそぼろ状である。したがって、そのままの状態の生地では、製パンまた は製麵に使用することができない。 However, it is still difficult to eliminate the non-uniform state of the mixture once generated. The mixture discharged from the mixing device has a so-called rag shape in which dough with insufficient moisture surrounds dough with excess moisture. Therefore, the raw dough cannot be used for bread making or koji making.
[0025] 従来において、小麦粉と水の混合に関する困難な問題を解決せんとする試みはな 力つた訳ではない。例えば、「小麦粉練り製品製造における加水熟成方法」に示され る技術 (特許文献 3)は、小麦粉と水とを微粒子状態にして直接接触させることを目指 している。 [0025] In the past, attempts to solve difficult problems related to mixing flour and water have not been successful. For example, the technique (Patent Document 3) shown in “Method of hydrolysis and maturation in the production of wheat flour kneaded products” aims at bringing flour and water into a fine particle state and bringing them into direct contact with each other.
[0026] し力しながら、特許文献 3の第 1図に示す実施例では、当然均一な混合の成否の鍵 を握るであろう噴霧の広がりや密度分布などを精密に制御する手段について具体策 が提示されていない。  However, in the embodiment shown in FIG. 1 of Patent Document 3, specific measures are taken for means for precisely controlling the spread and density distribution of the spray, which will naturally be the key to success or failure of uniform mixing. Is not presented.
[0027] すなわち、特許文献 3では、微粒水滴と結合済みの粒子に再度噴霧することを防ぎ 、結合が遅れた粒子に対して選択的に噴霧を行うようなメカニズムも無ぐ意図するよ うな均一混合を実現させることは難しい。特許文献 3における、他の実施例でも十分 な効果を期待し難い点は同様である。すなわち、目指している理想混合の具体的な 方法は提示されて ヽな ヽと言える。 [0027] That is, Patent Document 3 prevents re-spraying onto particles that have been combined with fine water droplets. Therefore, it is difficult to achieve uniform mixing as intended without a mechanism for selectively spraying particles with delayed bonding. It is the same in that it is difficult to expect a sufficient effect in other examples in Patent Document 3. In other words, the specific method of ideal blending that we are aiming for is presented as a fool.
[0028] 上述のように、粉体と液体との混合における従来技術の問題点こそ本発明が解決 しょうとする課題である。すなわち、従来技術の根本問題は、完全な混合を果たすた めには、 V、つたん混合した後に混練を行う必要がある。  [0028] As described above, the problem of the prior art in mixing powder and liquid is the problem to be solved by the present invention. In other words, the fundamental problem of the prior art is that in order to achieve complete mixing, it is necessary to knead after mixing V, just.
[0029] そこで、本発明では、混練工程なしに完全な混合を実現する方法を提供することを 目指す。特に、小麦粉と水の混合のように、混合後に生成される両者の反応物が重 要な物質であり、しかも十分な混合を完成させるためには避けられない機械的な作 用が、その重要物質を破壊するような場合、本発明の課題の重要性は極めて大きい 特許文献 1:英国特許 1242037号  Therefore, the present invention aims to provide a method for realizing complete mixing without a kneading step. In particular, the reaction between the two products generated after mixing is an important substance, such as the mixing of flour and water. In the case of destroying a substance, the importance of the subject of the present invention is extremely large. Patent Document 1: British Patent No. 1242037

[0049] <粉体原料の流れについて >  [0049] <Flow of powder raw material>
まず、粉体原料の流れを説明する。粉体ホッパー 1に粉体原料を入れる。多量生産 の場合は、この粉体ホッパー 1の上方に粉体定量供給装置を設けることが望ましい。  First, the flow of the powder raw material will be described. Powder raw material is put into the powder hopper 1. In the case of mass production, it is desirable to install a powder quantitative supply device above the powder hopper 1.
[0050] 次いで、粉体原料はスクリューフィーダ一用ホッパー 3に導かれる。この際の粉体原 料の移動は重力によるが、架橋や閉塞によるトラブルを防ぐためにバイブレータ 2を 粉体ホッパーまたはその下流位置に取り付けることが好ましい。  [0050] Next, the powder raw material is guided to the hopper 3 for the screw feeder. Although the movement of the powder raw material at this time depends on gravity, it is preferable to attach the vibrator 2 to the powder hopper or a downstream position thereof in order to prevent troubles due to cross-linking or blockage.
[0051] ケーシング 5に挿入されたスクリュー 4は、フィーダ一従動軸用軸受けボックス 9にて 回転可能に支持されている。そして、スクリュー 4は、フィーダ一用従動プーリ 6、フィ 一ダー用駆動プーリ 7、ベルトを介し、フィーダ一用駆動モーター 8によって回転駆動 する。  [0051] The screw 4 inserted into the casing 5 is rotatably supported by a feeder-follower shaft bearing box 9. The screw 4 is rotationally driven by a feeder driving motor 8 through a feeder driven pulley 6, a feeder driving pulley 7, and a belt.
[0052] すると、スクリューフィーダ一用ホッパー 3内の粉体原料は、スクリュー 4の回転に伴 い、ケーシング 5内を通って、粉体回転盤 10へ送られる。  [0052] Then, the powder raw material in the hopper 3 for the screw feeder 1 is sent to the powder rotating disk 10 through the casing 5 as the screw 4 rotates.
図 2は、図 1の X部分の拡大図である。図 3は、図 2の Y— Y部分の水平断面図であ り、粉体原料の流れ方、および混合物の排出状態を説明するために用いる。粉体回 転盤 10は、粉体回転盤用軸受け 12及び粉体回転盤用軸受け 12aによって回転可 能に支持された粉体回転盤用軸 11に固定されている。そして、粉体回転盤 10は、 粉体回転盤用従動プーリ 13および粉体回転盤用駆動プーリ 14、ベルトを介して粉 体回転盤用駆動モーター i 5にて回転される。 FIG. 2 is an enlarged view of a portion X in FIG. FIG. 3 is a horizontal cross-sectional view of the Y—Y portion of FIG. 2 and is used to explain the flow of the powder raw material and the discharge state of the mixture. The powder rotating disk 10 is fixed to a powder rotating disk shaft 11 rotatably supported by a powder rotating disk bearing 12 and a powder rotating disk bearing 12a. The powder rotating disk 10 includes a powder rotating disk driven pulley 13, a powder rotating disk driving pulley 14, and a powder via a belt. It is rotated by the body rotating disk driving motor i 5.
[0053] スクリュー 4の作用によってスクリューフィーダ一用ホッパー 3より搬送された粉体原 料は、粉体回転盤 10に固定された粉体分散体 16の上面中心部に形成された凹部 である粉体受け部 16aに誘導される。 [0053] The powder raw material conveyed from the hopper 3 for the screw feeder 1 by the action of the screw 4 is a powder which is a recess formed in the center of the upper surface of the powder dispersion 16 fixed to the powder rotating disk 10. It is guided to the body receiving part 16a.
[0054] そうすると、粉体原料が粉体受け部 16aの表面に接触して生じる摩擦力により、粉 体原料は円周方向に回転を始める。そして、その回転により粉体は、粉体受け部 16 aの上方に舞い始めると、粉体原料は、粉体分散体 16の回転により回転している気 流に乗って回転する。 Then, the powder material starts to rotate in the circumferential direction due to the frictional force generated when the powder material contacts the surface of the powder receiving portion 16a. Then, when the powder starts to flutter above the powder receiving portion 16 a due to the rotation, the powder raw material rotates on the air rotating by the rotation of the powder dispersion 16.
[0055] これらの回転によって生じた遠心力により粉体受け部 16a上の粉体原料は半径方 向に運動して、同一円周上に複数枚配置された凝集塊破砕歯 17に衝突する。する と、粉体原料中の凝集塊は破砕されて、ばらばらな粉体粒子群になる。  [0055] The centrifugal force generated by these rotations causes the powder raw material on the powder receiving portion 16a to move in the radial direction and collide with agglomerate crushing teeth 17 arranged on the same circumference. Then, the agglomerates in the powder raw material are crushed into discrete powder particle groups.
[0056] 凝集塊破砕歯 17の隙間を通過した粉体原料は、粉体分散カップ 18および粉体分 散体 16に囲まれた空間である粉体受け部 72に入る。粉体分散カップ 18は、スクリュ 一フィーダ一用ホッパー 3と共にケーシング用ブラケット 20に固定されていて回転は していない部材である。  The powder raw material that has passed through the gaps between the agglomerate crushing teeth 17 enters the powder receiving portion 72 that is a space surrounded by the powder dispersion cup 18 and the powder dispersion body 16. The powder dispersion cup 18 is a member which is fixed to the casing bracket 20 together with the screw feeder 1 hopper 3 and is not rotated.
[0057] 粉体受け部 72に入った粉体原料は、引き続き粉体分散体 16から回転力を与えら れ、粉体分散カップ 18と粉体回転盤 10との隙間、すなわち粉体分散カップ下の隙 間部 70から外側に向けて 360度全方向へ均等に流出する。  [0057] The powder raw material that has entered the powder receiver 72 is continuously applied with a rotational force from the powder dispersion 16, and the gap between the powder dispersion cup 18 and the powder turntable 10, that is, the powder dispersion cup. Outflows in all directions 360 degrees outward from the lower gap 70.
[0058] この流出が均等であることは、混合の均一性を実現させる上で極めて重要である。  [0058] The uniformity of the outflow is extremely important in achieving uniformity of mixing.
流出を均等にして混合の均等性を安定して実現させる手段は 3つある。第 1の流出 均一化手段は、凝集塊破砕歯 17が予め粉体原料をばらばらの粒子群にすることで ある。第 2の流出均一化手段は、粉体分散カップ 18が回転していないために、中速 で回る粉体回転盤 10との狭い隙間(粉体受け部 72)に挟まれた粉体には周方向に 流動が与えられていることである。第 3の流出均一化手段は、粉体分散カップ 18下の 隙間部 70の幅が方向によらず均等であることである。  There are three ways to achieve uniform flow uniformity and uniform mixing. A first outflow homogenizing means is that the agglomerate crushing teeth 17 make the powder raw material into discrete particle groups in advance. The second outflow homogenizing means is for the powder sandwiched in a narrow gap (powder receiving part 72) with the powder rotating disk 10 rotating at medium speed because the powder dispersion cup 18 is not rotating. The flow is given in the circumferential direction. A third outflow uniformizing means is that the width of the gap portion 70 under the powder dispersion cup 18 is uniform regardless of the direction.
[0059] 以上の 3つの流出均一化手段の総合作用により、粉体原料の凝集塊が隙間部 70 の一部を閉塞することは生じない。また、粉体ホッパー 1におけるブリッジング (粒が 均等な力で孔に落ちていくため、上でアーチ状につつかかる現象のこと)により完全 に流れが止まることも、方向によって流出した粉体原料の層厚に分布が生じるような ことも無いので、粉体原料の流出は常に全周均等になされる。 [0059] Due to the combined action of the above three outflow homogenizing means, the agglomerates of the powder raw material do not block part of the gap 70. In addition, it is completely achieved by bridging in the powder hopper 1 (the phenomenon that the particles fall into the holes with an equal force and are arched above). Therefore, there is no distribution of the thickness of the powder material that has flowed out depending on the direction, so that the powder material always flows out evenly.
[0060] 360度方向に放射された粉体原料を合計した流出量も以上の 3つの流出均一化手 段が奏効して一定になる。また、粉体分散カップ 18下の隙間部 70の大きさは、後述 する混合条件の最適化や時間当りの生産量に見合った、適度の寸法に設定されて いる。  [0060] The total outflow amount of the powder raw materials radiated in the 360-degree direction becomes constant due to the effect of the above three outflow equalization methods. In addition, the size of the gap 70 under the powder dispersion cup 18 is set to an appropriate size in accordance with optimization of the mixing conditions described later and production per hour.
[0061] 粉体分散カップ 18下の隙間部 70からの粉体原料の流出量を決定するもう 1つの要 因は、粉体回転盤 10の回転数である。この粉体回転盤 10の回転数は、無段階に調 節可能なようにしておくことが好ましい。この場合、粉体回転盤用駆動モーター 15は 回転数が無段階に調節可能な型式のもの、例えば直流モーターを選定することがで きる。このとき、この直流モーターは、混合物の生産量と必要品質を満たす範囲、例 えば毎分 500から 2000回転の範囲の中で適度な値に設定される。  [0061] Another factor that determines the amount of powder raw material flowing out from the gap 70 under the powder dispersion cup 18 is the rotational speed of the powder rotating disk 10. It is preferable that the rotational speed of the powder rotating disk 10 be adjusted steplessly. In this case, the powder rotating disk drive motor 15 can be selected from a type whose rotation speed can be adjusted steplessly, for example, a DC motor. At this time, the DC motor is set to an appropriate value in a range that satisfies the production amount and required quality of the mixture, for example, in the range of 500 to 2000 revolutions per minute.
[0062] 例えば毎分 2kgの小麦粉の水和を行う場合、粉体分散カップ 18の内径を φ 65mm とすると、隙間部 70は lmm程度、粉体回転盤 10の回転数は毎分 1000回転が適当 である。  [0062] For example, when hydrating 2 kg of flour per minute, if the inner diameter of the powder dispersion cup 18 is φ65 mm, the gap 70 is about lmm, and the rotational speed of the powder rotating disk 10 is 1000 revolutions per minute. Appropriate.
[0063] 粉体分散カップ 18下の隙間部 70を通過すると、粉体原料は、粉体回転盤 10との 接触による摩擦力および気流を介して回転力を与えられ、生じた遠心力によって半 径方向にも次第に加速され、層厚を減じながら粉体回転盤 10の外周部へ移動する。  [0063] After passing through the gap 70 under the powder dispersion cup 18, the powder raw material is given a rotational force through a frictional force and an air flow caused by contact with the powder rotating disk 10, and a half force is generated by the generated centrifugal force. It is also accelerated in the radial direction and moves to the outer periphery of the powder rotating disk 10 while reducing the layer thickness.
[0064] そして、その粉体原料は最外周部に達するよりも手前の位置で、後述する液体原 料と遭遇する。その時の粉体原料の層厚は理想的な混合に望ましい寸法、すなわち 後にその理由を述べるが、粉体原料の平均粒子径の数倍になっている。粉体原料の 流出時の層厚は、粉体分散カップ 18下の隙間部 70の大きさ及び粉体回転盤 10の 回転数によって広範囲にしかも正確に調節可能である。  [0064] Then, the powder raw material encounters a liquid raw material to be described later at a position before reaching the outermost peripheral portion. The layer thickness of the powder raw material at that time is a dimension desirable for ideal mixing, that is, the reason will be described later, and is several times the average particle diameter of the powder raw material. The layer thickness when the powder raw material flows out can be adjusted over a wide range and accurately by the size of the gap 70 under the powder dispersion cup 18 and the rotation speed of the powder rotating disk 10.
[0065] この他に粉体原料の流出時の層厚を決定する因子として、粉体回転盤 10の上面 形状がある。仮に、粉体回転盤 10の形状が平面であると、回転円盤上の粉体は層厚 が減じるに従って盤に引きずられて旋回する気流に支配されるようになり、粉体の粒 子がばらばらになって密度が減り、見掛けの層厚は増える傾向を示す。  Another factor that determines the layer thickness when the powder raw material flows out is the shape of the upper surface of the powder rotating disk 10. If the shape of the powder rotating disk 10 is flat, the powder on the rotating disk will be controlled by the swirling airflow dragged to the disk as the layer thickness decreases, and the particles of the powder will fall apart. As a result, the density decreases and the apparent layer thickness increases.
[0066] し力しながら、後述する理由により、より好ましい結果が得られる形状すなわち外側 に向けて昇り勾配になる形状を選ぶと、遠心力によって粉体の粒子は回転盤の表面 に沿って進もうとする。 [0066] A shape that gives a more preferable result for the reason described later, If a shape with an ascending slope is selected, the powder particles will move along the surface of the rotating disk by centrifugal force.
[0067] 従って、粉体原料の密度は高めに保たれ層厚は薄くなる。この勾配は混合が行わ れる箇所で特に重要であるが、後述する理由により 1度以上 10度以下が適当である ので、その内側の部分でも同じかそれ以下とすることが好ましい。  Therefore, the density of the powder raw material is kept high and the layer thickness is reduced. This gradient is particularly important at the place where mixing is performed, but for the reasons described later, it is appropriate that the angle is 1 degree or more and 10 degrees or less.
[0068] <液体原料の流れについて >  [0068] <Flow of liquid raw material>
次に、液体原料の流れを述べる。ここでは、図 4を参照しながら説明する。液体供給 ノズル 33からは一定の流量にコントロールされた液体原料が流出し、噴霧器 22の液 体受け部 34に注入される。噴霧器 22は、本実施例では、円筒形の回転軸 22a先端 にベル状のカップが結合したものを回転させることにより、その遠心力でそのカップ口 力 液体を噴霧するものを用いて 、る。  Next, the flow of the liquid raw material will be described. Here, a description will be given with reference to FIG. From the liquid supply nozzle 33, a liquid raw material controlled at a constant flow rate flows out and is injected into the liquid receiver 34 of the sprayer 22. In the present embodiment, the sprayer 22 is a sprayer which sprays the liquid with the centrifugal force by rotating a bell-shaped cup coupled to the tip of a cylindrical rotary shaft 22a.
[0069] 噴霧器 22の円筒部分 22aケーシング 5を覆って 、る構造となって 、る。噴霧器 22 の円筒部分は、噴霧器用軸受け 23と噴霧器用軸受け 23aによって回転支持されて おり、噴霧器用従動プーリ 24、噴霧器用駆動プーリ 25および Vベルト 26によって高 速で回転している。  [0069] The cylindrical portion 22a of the sprayer 22 covers the casing 5, and has a structure as described above. The cylindrical portion of the sprayer 22 is rotatably supported by a sprayer bearing 23 and a sprayer bearing 23a, and is rotated at a high speed by a sprayer driven pulley 24, a sprayer drive pulley 25, and a V-belt 26.
[0070] 液体原料が液体供給ノズル 33より供給されて噴霧器 22の液体受け部 34の底面に 接触する。そうすると、噴霧器 22の高速回転により、その液体は即座に噴霧器 22の 液体受け部 34内の内径の大きい壁側 (液体受け部の内周部 35)に溜まる。そうする と、その液体は直ちに壁側 (液体受け部の内周部 35)の下方に設けられた液体導入 孔 36に流入して噴霧器 22の液体受け部 37に達する。  The liquid raw material is supplied from the liquid supply nozzle 33 and comes into contact with the bottom surface of the liquid receiving portion 34 of the sprayer 22. Then, due to the high-speed rotation of the sprayer 22, the liquid immediately accumulates on the wall side (inner peripheral part 35 of the liquid receiver) having a large inner diameter in the liquid receiver 34 of the sprayer 22. As a result, the liquid immediately flows into the liquid introduction hole 36 provided below the wall side (inner peripheral portion 35 of the liquid receiving portion) and reaches the liquid receiving portion 37 of the sprayer 22.
[0071] その液は、噴霧器 22の回転により、液体受け部 37の天井部分に沿って径の大きい 方へ流れ、液体受け部 37の外周壁 38に達する。その液が内径の大きい箇所に溜ま ると、やがて液体受け部 37のダム部 39からオーバーフローする。  The liquid flows toward the larger diameter along the ceiling portion of the liquid receiving portion 37 by the rotation of the sprayer 22 and reaches the outer peripheral wall 38 of the liquid receiving portion 37. When the liquid accumulates at a location with a large inner diameter, it eventually overflows from the dam portion 39 of the liquid receiving portion 37.
[0072] すると、そのオーバーフローした液は、極めて大きい遠心力を受けつつ噴霧器内壁 部 40に沿って 100 m以下の極めて薄い液膜になって流れ、外周部に向力うに従 つて更に薄くなる。  Then, the overflowed liquid flows as an extremely thin liquid film of 100 m or less along the inner wall part 40 of the sprayer while receiving an extremely large centrifugal force, and becomes thinner as it is directed to the outer peripheral part.
[0073] ここで、噴霧器 22のベルカップの口部分 (先端部 41)は粉体回転盤 10の上面と所 定の空間を隔てた位置に設置されている。この噴霧器 22のベルカップの口部分 (先 端部 41)と粉体回転盤 10の上面との間の隙間を隙間 73で表す。 Here, the mouth portion (tip portion 41) of the bell cup of the sprayer 22 is installed at a position separating the upper surface of the powder rotating disk 10 from a predetermined space. The mouth part of the bell cup of this sprayer 22 A gap between the end 41) and the upper surface of the powder rotating disk 10 is represented by a gap 73.
[0074] 噴霧器先端部 41に液膜が達すると、支えを失った液膜は遠心力によって無数の微 細な液滴に変化する。その粒子径は噴霧器 22の回転数に依存し、回転数が高いほ ど微粒になる。目標とすべき粒子径は粉体原料の平均粒子径程度力もしくはより細 かい値である。 [0074] When the liquid film reaches the tip 41 of the sprayer, the liquid film that has lost its support is changed into countless fine droplets by centrifugal force. The particle diameter depends on the rotation speed of the atomizer 22, and the higher the rotation speed, the finer the particles. The target particle size should be about the average particle size of the powder raw material or a finer value.
[0075] し力しながら、高速回転になるほど騒音や振動の発生、装置の寿命が短命になるな どの問題が生じ易い。したがって、例えば噴霧器先端部 41の直径が 118mmの場合 、要求品質と操業条件との兼ね合いで、毎分 8000回転〜 15000回転の範囲の中 で適当な値が選ばれる。  [0075] However, as the rotation speed increases, problems such as generation of noise and vibration, and shorter life of the apparatus are more likely to occur. Therefore, for example, when the diameter of the tip 41 of the sprayer is 118 mm, an appropriate value is selected in the range of 8000 to 15000 revolutions per minute in view of the required quality and operating conditions.
[0076] この場合、噴霧器先端部 41からは微細な液滴群が秒速 49m〜93mの速度で水平 方向と水平より僅かに下向きの角度の範囲に拡散しつつ飛散する。液滴の向力う先 は前述の粉体回転盤 10の上面において外周部力も少し内側の箇所であり、この箇 所を粉体と霧状液体の混合部 71と呼ぶ。  [0076] In this case, a fine droplet group is scattered from the sprayer tip 41 while diffusing in the horizontal direction and a slightly downward angle range from the horizontal at a speed of 49m to 93m per second. The tip of the droplet is the portion on the upper surface of the powder rotating disk 10 where the outer peripheral force is slightly inside, and this portion is referred to as the powder / mist liquid mixing portion 71.
[0077] 混合部 71は本発明による混合装置の最も重要な箇所であり、この付近の粉体回転 盤 10の上表面形状によって混合の均一性が決定される。混合部 71での混合の状況 について、図 5にて詳述する。  [0077] The mixing unit 71 is the most important part of the mixing apparatus according to the present invention, and the uniformity of mixing is determined by the upper surface shape of the powder rotating disk 10 in the vicinity thereof. The state of mixing in the mixing unit 71 is described in detail in FIG.
[0078] <粉体原料と液体原料の混合につ!、て >  [0078] <Mixing of powder raw material and liquid raw material!
図 5は、本発明における小麦粉と水との混合の様子を説明するための図である。同 図は、粉体回転盤 10上で小麦粉と水とが混合が行われる部分 (混合部 71)において 、小麦粉粒子と微粒水滴とが結合する状況を、段階を追って説明している。混合部 7 1の内、粉体回転盤 10の中心軸に近い位置を A位置、遠い位置を C位置、中間を B 位置とする。  FIG. 5 is a diagram for explaining a state of mixing flour and water in the present invention. This figure explains step by step how the flour particles and fine water droplets are combined in the portion where the flour and water are mixed on the powder rotating disk 10 (mixing unit 71). Of the mixing unit 71, the position close to the central axis of the powder turntable 10 is A position, the far position is C position, and the middle is B position.
[0079] A位置で小麦粉と水滴との混合が始まる。このとき、回転しながら外向きに運動する 小麦粉層の表面の粒子に対して、平面的にはほぼ同じ方向に運動する水滴力 浅 い角度で斜め上方力も衝突する。  [0079] Mixing of flour and water droplets begins at position A. At this time, the water droplet force that moves in the same direction in a plane also collides with the diagonal upward force at a shallow angle against the particles on the surface of the flour layer that moves outward while rotating.
[0080] その衝突の際の粒子速度は小麦粉が例えば秒速約 9m (粉体回転盤 10の回転数 力 SlOOOrpmの場合)に対して、水滴の速度は例えば噴霧器 22の回転数を毎分 150 00回転とした場合は秒速 93mであり、約 10倍大きい。この場合、水と結合して水分 を含んだ小麦粉粒子は衝突の瞬間に速度を大幅に増し、運動の向きも下方に転じ、 小麦粉層の深いところ、すなわち粉体回転盤 10の表面近くに向力つて移動する。そ の小麦粉粒子の移動量は、受けた水滴の大きさに左右される。 [0080] The particle velocity at the time of the collision is, for example, about 9 m per second for flour (when the rotational speed of the powder rotating disk 10 is SlOOOrpm), and the speed of the water droplet is, for example, the rotational speed of the sprayer 22 at 150 00 / min. In the case of rotation, the speed is 93 m / s, which is about 10 times larger. In this case, it combines with water The flour particles containing slag increase the speed at the moment of collision, the direction of motion also turns downward, and move toward the deep part of the flour layer, that is, near the surface of the powder rotating disk 10. The amount of movement of the flour particles depends on the size of the received water droplets.
[0081] B位置に達すると、小麦粉層の下半分には水滴と結合済みの小麦粉粒子が増える 。逆に表層には未だ水滴と結合して 、な 、粒子や水分の割合が少な 、小麦粉粒子 が浮上して存在しているので、水滴は主に未結合の小麦粉粒子に衝突する。すなわ ち、上下層の入れ替わりによる均一化メカニズムが働きながら小麦粉と水滴の結合が 進む。  [0081] When the position B is reached, the lower half of the flour layer has more flour particles combined with water droplets. On the contrary, the surface layer still binds to the water droplets, and the ratio of particles and moisture is low, and the flour particles float and exist, so the water droplets mainly collide with the unbound flour particles. In other words, the combination of flour and water droplets proceeds while the homogenization mechanism works by switching the upper and lower layers.
[0082] 一方、水滴の追突を受けて、粉体回転盤 10上の小麦粉層の流動速度も大幅に増 カロしている。し力しながら、 C位置に近づくにつれて、水滴と結合済みの小麦粉粒子 の割合が増えていく。そのため、含水小麦粉の相互粘着によって小麦粉層の流動性 が減るので、上下層の入れ替わりのための小麦粉層の移動が不自由になってくる。  [0082] On the other hand, the flow velocity of the flour layer on the powder rotating disk 10 is greatly increased due to the rear-end collision of the water droplets. However, as it approaches the C position, the proportion of water droplets and bound flour particles increases. For this reason, the fluidity of the flour layer decreases due to the mutual adhesion of the water-containing flour, which makes it impossible to move the flour layer for the replacement of the upper and lower layers.
[0083] 従って、より大きい加速度を与えて小麦粉層の移動を促すことが望ましい。具体的 には、混合部 71において図 5に示す C位置での粉体回転盤 10の断面形状を凹面状 にするとよい。  [0083] Accordingly, it is desirable to increase the acceleration of the flour layer by applying a greater acceleration. Specifically, the cross-sectional shape of the powder rotating disk 10 at the position C shown in FIG.
[0084] なぜならば、遠心力は半径に反比例するために、大きな曲率半径でもって高速で 流れる粒子の流れが小さな曲率半径の円運動に変わると、粒子にはより強い遠心力 が働くからである。  [0084] Because the centrifugal force is inversely proportional to the radius, if the flow of particles flowing at a high speed with a large radius of curvature changes to a circular motion with a small radius of curvature, a stronger centrifugal force acts on the particles. .
[0085] 例えば、粉体回転盤 10の中心から C位置付近までの距離を 80mm、図 5中の Rで 示す曲率半径を 20mm、粉体回転盤 10の回転数を lOOOrpmとした場合、 A位置か ら B位置の単純な昇り勾配の箇所での遠心加速度 (働く向きは水平方向である)は 9 OG以下 (Gは重力の加速度)である。  [0085] For example, when the distance from the center of the powder turntable 10 to the vicinity of the C position is 80 mm, the radius of curvature indicated by R in FIG. 5 is 20 mm, and the rotation speed of the powder turntable 10 is lOOOrpm, the A position Therefore, the centrifugal acceleration (the working direction is horizontal) at a simple ascending slope at position B is 9 OG or less (G is the acceleration of gravity).
[0086] このとき、小麦粉層の半径方向の速度は毎秒約 23m (水分添加が重量比で小麦粉 の 40%まで進んだと仮定して)となるので、小麦粉層には 2700G以上もの加速度が 生じる。し力も加速度の向きは小麦粉層に垂直であるので、重い粒子と軽い粒子の 入れ替わりを促す作用が格段に強化される。  [0086] At this time, the speed of the flour layer in the radial direction is about 23 m per second (assuming that the addition of water has progressed to 40% of the flour by weight), so that the acceleration of 2700 G or more occurs in the flour layer . Since the direction of acceleration is also perpendicular to the flour layer, the action of encouraging the exchange of heavy and light particles is greatly enhanced.
[0087] 力べして、各小麦粉粒子は表層で水滴を受けるたびに下層へ沈み込み、その反動 で比較的軽い粒子は上層へ浮かび上がり、移動距離も僅かである。こうして、各小麦 粉粒子の沈み込みと浮き上がりは繰り返し行われる。 [0087] By force, each flour particle sinks to the lower layer each time it receives water droplets on the surface layer, and by reaction, relatively light particles rise to the upper layer, and the moving distance is slight. Thus, each wheat The sinking and lifting of the powder particles are repeated.
[0088] 小麦粉粒子が C位置付近を通過する時間は 1ミリ秒にも満たな 、ほど短 、が、加速 度が大きく移動距離が小さいゆえに、小麦粉粒子の移動には十分な時間であり、入 れ替わりは十分に行われる。  [0088] The time for the flour particles to pass near the C position is less than 1 millisecond, but it is short enough, but because the acceleration is large and the moving distance is short, it is sufficient time for the flour particles to move. The replacement is sufficient.
[0089] 以上のように、力学の法則に従った作用によって小麦粉層における表層部と深層 部の入れ替えが活発に起こり、混合部 71を移動する間に小麦粉と水との均一な混合 が確実に達成される。 [0089] As described above, the surface layer portion and the deep layer portion in the flour layer are actively exchanged by the action according to the laws of mechanics, and the uniform mixing of the flour and water is ensured while moving the mixing portion 71. Achieved.
[0090] し力しながら、小麦粉層の厚みが厚過ぎると、このような上下層の入れ替え現象が 十分には生じない。逆に小麦粉層の厚みが薄過ぎると、小麦粉に衝突しないまま直 接粉体回転盤 10の表面に達してその表面を無用に濡らす、或いは、反射して再び 小麦粉層を突き抜けて小麦粉粒子と結合しないまま散逸する水滴粒子が生じるなど の問題が生じる。  [0090] However, if the thickness of the flour layer is too thick, such a phenomenon of switching between the upper and lower layers does not occur sufficiently. On the contrary, if the thickness of the flour layer is too thin, it directly reaches the surface of the powder rotating disk 10 without colliding with the flour and wets the surface unnecessarily, or reflects and penetrates the flour layer again to combine with the flour particles. Problems such as the generation of water droplet particles that dissipate without being generated.
[0091] すなわち、小麦粉層の厚みには最適な範囲があり、それは小麦粉の平均粒子径の 数倍であって 100〜200 μ m程度である。この程度の厚さであれば粒子の移動距離 は極めて小さいので、小麦粉層が混合部 71を移動する間に、上下層の入れ替えは 繰り返し行われる。しカゝも、水滴粒子は貫通または反射することなく全て小麦粉層に 吸収されて、均質な混合物の層が完成する。既に述べたように、層厚の調節は粉体 分散カップ下の隙間部 70の大きさおよび粉体回転盤 10の回転数によって、広範囲 にし力も正確に行うことができる。  That is, the thickness of the flour layer has an optimum range, which is several times the average particle diameter of the flour and is about 100 to 200 μm. Since the moving distance of the particles is very small at such a thickness, the upper and lower layers are repeatedly exchanged while the flour layer moves through the mixing section 71. However, all the water droplet particles are absorbed by the flour layer without penetrating or reflecting, and a layer of a homogeneous mixture is completed. As described above, the adjustment of the layer thickness can be performed over a wide range and the force can be accurately performed according to the size of the gap 70 under the powder dispersion cup and the rotational speed of the powder rotating disk 10.
[0092] その後、小麦粉粒子と水滴との混合物は引き続き半径方向にも加速されながら粉 体回転盤 10の表面上を移動する。加水率が 60%を越す場合、この段階に達すると 混合物には粘着性が生じている。  Thereafter, the mixture of the flour particles and the water droplets moves on the surface of the powder rotating disk 10 while being accelerated in the radial direction. When the water content exceeds 60%, the mixture becomes sticky when this stage is reached.
[0093] 混合物は回転運動をしているので強い遠心力が働いており、実際には粉体回転盤 10への粘着は生じにくい。し力しながら、クリーニングの容易性を考慮して粉体回転 盤 10の上表面には粘着を防ぐための表面処理、例えば弗素樹脂のコーティングを 施しておくことが好ましい。  [0093] Since the mixture is rotating, a strong centrifugal force is acting, and in reality, sticking to the powder rotating disk 10 hardly occurs. However, considering the ease of cleaning, the upper surface of the powder rotating disk 10 is preferably subjected to a surface treatment for preventing adhesion, such as a coating of fluorine resin.
[0094] 混合物が粉体回転盤 10の最外周部に達すると、遠心力にて粉体回転盤 10のテー ブル部分力も離脱し、粉体回転盤 10の上表面の傾斜角に依存した角度、すなわち やや上向き方向へ飛散する。 [0094] When the mixture reaches the outermost periphery of the powder turntable 10, the table partial force of the powder turntable 10 is also released by centrifugal force, and the angle depends on the inclination angle of the upper surface of the powder turntable 10. I.e. Slightly fly upward.
[0095] そして、その飛散した混合物は、すぐに混合物反射体 51に衝突すると反射して下 方へ運動方向を変える。そして、その混合物は、混合物受け 52の水平部分の表面 に着地し、混合物受け 52と共に回転を始める。  [0095] Then, when the scattered mixture immediately collides with the mixture reflector 51, it is reflected and changes its direction of movement downward. The mixture then lands on the surface of the horizontal portion of the mixture receiver 52 and begins to rotate with the mixture receiver 52.
[0096] なお、混合物が粘着するような物性を示す場合は混合物反射体 51に付着堆積す る不具合が生じるので、混合物反射体 51の反射面に弗素榭脂などの付着防止材を コーティングすることが好まし 、。  [0096] If the mixture exhibits physical properties such that the mixture adheres to the mixture reflector 51, a problem of adhering and depositing on the mixture reflector 51 occurs. Is preferred.
[0097] また、混合物が極端に粘着しやす!/ヽ場合、例えば加水率が 65%を越す混合を行う ような場合には、図示しない加熱装置にて混合物反射体 51を 120°C〜140°Cに保 つことで、或 、は混合物反射体 51に図示しな 、加振器を取付けることで対策できる。  [0097] Also, when the mixture is extremely sticky! / ヽ, for example, when mixing with a water content exceeding 65%, the mixture reflector 51 is placed at 120 ° C to 140 ° C with a heating device (not shown). It can be counteracted by keeping the temperature at ° C or by attaching a vibrator to the mixture reflector 51 (not shown).
[0098] 混合物受け 52には、混合物反射体 51に反射して落下した混合物 80が堆積する。  In the mixture receiver 52, the mixture 80 that has been reflected by the mixture reflector 51 and dropped is deposited.
混合物受け 52は、混合物受け用軸受け 58に支えられつつ低速で回転している。従 つて、混合物 80は、混合物反射体 51と混合物受け 52とに挟まれた、ドーナツ状の空 間内で回転する。なお、本実施例では、混合物受け用軸受け 58にはモーメント荷重 をも担うことができるタイプのボールベアリングを用いて、装置のコンパクトィ匕を図って いる。  The mixture receiver 52 rotates at a low speed while being supported by the mixture receiving bearing 58. Therefore, the mixture 80 rotates in a donut-shaped space sandwiched between the mixture reflector 51 and the mixture receiver 52. In this embodiment, a ball bearing of a type capable of bearing a moment load is used for the mixture receiving bearing 58 to achieve a compact device.
[0099] そして、混合物 80は、混合物排出シュート 60の真上に配置された混合物排出スク レーパ 59の作用により混合物受け 52の底面および壁面から機械的に離脱させられ る。その離脱した混合物は、重力によって下方に向力ぃ、混合物排出シュート 60内 を落下する。その後、図示しない容器や混合物排出ベルトコンベアなどで次の工程 へ搬送される。  [0099] The mixture 80 is mechanically separated from the bottom surface and the wall surface of the mixture receiver 52 by the action of the mixture discharge scraper 59 disposed right above the mixture discharge chute 60. The separated mixture is directed downward by gravity and falls in the mixture discharge chute 60. Then, it is transported to the next process by a container (not shown) or a mixture discharge belt conveyor.
[0100] この主に小麦粉と水とで成る混合物(生地)は、既にほぼ均質な状態であるため、そ のまま製麵あるいは製パンのための成形が可能である。ダルテンの網目組織を製品 に適した形態に発達させるには、純粋に練りを目的とした穏やかな塑性流動をローラ 一などで加え、結合組織の損傷を避けながら、生地を望むように改質させることがで きる。  [0100] Since the mixture (dough) mainly composed of flour and water is already in a nearly homogeneous state, it can be formed as it is for baking or baking. In order to develop the Dalten network into a form suitable for the product, a gentle plastic flow purely for kneading is applied with a roller, etc., and the dough is modified as desired while avoiding damage to the connective tissue. be able to.
[0101] <他の実施例 >  [0101] <Other examples>
本実施例では、噴霧器 22に自動車塗装などによく用いられるベル状カップを用い たが、これに限定されない。噴霧器 22は、軸対称に微細な霧を水平方向に近い角度 で放射できるものであればよぐ例えば、図 6に示すようなスプレードライヤーに用いら れる噴霧盤方式でもよい (例えば、特許文献 4)。 In this embodiment, a bell-shaped cup often used for automobile painting or the like is used for the sprayer 22. However, it is not limited to this. The sprayer 22 is not particularly limited as long as it can radiate a fine mist with axial symmetry at an angle close to the horizontal direction. For example, the sprayer 22 used in a spray dryer as shown in FIG. 6 may be used (for example, Patent Document 4). ).
[0102] 図 6は、本発明の他の実施例における噴霧盤方式を採用した場合の噴霧器 61を 示す。噴霧器 61は、ベル状カップ型噴霧器 22のカップ口に対してカップ先端の円周 縁部に液溜り部 62と、多数の孔(噴出孔) 63を設けたものである。液溜り部 62を設け ることにより、薄膜状でカップ内壁を伝った液体が液溜り部 62で一旦留まる。その後 、その液溜り部 62に溜まった液体は、噴出孔 63の内壁を伝わって噴出孔 63の開口 部分力 均一に微細な水滴状で放出される。  [0102] FIG. 6 shows a sprayer 61 in the case of employing a spray disk system in another embodiment of the present invention. The sprayer 61 is provided with a liquid reservoir 62 and a large number of holes (spout holes) 63 at the circumferential edge of the cup tip with respect to the cup mouth of the bell-shaped cup sprayer 22. By providing the liquid reservoir 62, the liquid that has passed through the inner wall of the cup in the form of a thin film temporarily stops at the liquid reservoir 62. After that, the liquid accumulated in the liquid reservoir 62 is discharged along the inner wall of the ejection hole 63 uniformly in the form of fine water droplets at the opening partial force of the ejection hole 63.
[0103] この噴霧盤方式による噴霧器 61では、液体原料は、上述した実施例に示すベル状 カップ型噴霧器 22と同様の過程を経てから、液溜まり 62に達する。この箇所では液 に極めて大き 、遠心力が働 、て 、るため、直ちに数多く設けられて 、る 63へ流入す る。  [0103] In the sprayer 61 using this spraying plate system, the liquid material reaches the liquid reservoir 62 after undergoing the same process as the bell-shaped cup sprayer 22 shown in the above-described embodiment. At this point, the liquid is extremely large and centrifugal force acts on it, so a large number of them are immediately provided and flow into 63.
[0104] それから孔 63の壁に沿って極めて薄い膜状を成しつつ流れて出口に達すると、無 数の微粒の液滴とィ匕して噴出する。構造はやや複雑になり装置製作のコストが増す 力 ベル状カップよりも液滴粒子を多量に放射できる特徴を持つ。したがって、毎分 1 OOOcc以上の液体原料の噴霧を必要とする比較的大型の装置に適用される。  [0104] Then, when it flows along the wall of the hole 63 while forming a very thin film and reaches the outlet, it is ejected as innumerable fine droplets. The structure is slightly complicated and the cost of manufacturing the device is increased. It has the feature that it can emit a larger amount of droplet particles than a bell-shaped cup. Therefore, it is applied to relatively large equipment that requires spraying liquid raw materials of 1 OOOcc or more per minute.
[0105] く小麦粉製品の製造について >  [0105] Production of wheat flour products>
次に、本発明の装置を用いて、実際にパンや麵類を製造する場合について述べる 。先ず製パンであるが、多くの場合、小麦粉にイースト菌、食塩、砂糖などを加える。 これらは予め液体原料に加えて水溶液にしておけばよ 、。  Next, a case where bread or potatoes are actually produced using the apparatus of the present invention will be described. First of all, it is bread making. In many cases, yeast, salt, sugar, etc. are added to the flour. These should be prepared in addition to the liquid raw material in advance.
[0106] 問題は食パンやバターロール、フランスパンなどの多くの種類のパンにバターゃシ ョートユングなどの油脂添カ卩が必要なことである。その重量は多い場合は水 100に対 し 25にも達する。  [0106] The problem is that many types of bread, such as white bread, butter roll, and French bread, require oil and fat-added coffee such as butter shyte jung. When the weight is large, it reaches 25 for 100 water.
[0107] 従来技術の製法では、油脂によるダルテン生成の妨害が顕著に生じる。よって、本 実施例では、始め力 油脂をミキサーに投入することはせず、水和がある程度進んだ 段階になって力も投入し、水和と油脂の混合が同時に完了するようにしている。  [0107] In the production method of the prior art, the obstruction of dartene production due to fats and oils occurs remarkably. Therefore, in the present embodiment, power oil and fat are not initially charged into the mixer, and the hydration is advanced to some extent and power is also applied so that the mixing of hydration and oil and fat is completed at the same time.
[0108] し力しながら、本実施例では油脂の途中の投入は不可能であるので、完全な水和 が完成した後に油脂の投入を行う。例えば、攪拌翼を有する縦型ミキサーに水和を 終えた生地と必要な油脂を投入し、攪拌翼を低速で回転させてダルテンの破壊を抑 えながら混合すればよい。 [0108] However, in this example, it is impossible to add oil or fat in the middle of this embodiment. After completion of, oil and fat is charged. For example, the hydrated dough and the necessary oils and fats may be put into a vertical mixer having a stirring blade, and mixed while suppressing the destruction of dartene by rotating the stirring blade at a low speed.
[0109] 従来の製法では水和が生地内の所々で完了していない状態で油脂を投入すること もあり、所々で油脂のみが小麦粉と結合してダルテンが所々で欠落している。一方、 本発明の方法では従来よりもはるかに緻密なダルテン組織がむら無く生成されるの は当然のことである。  [0109] In the conventional manufacturing method, fats and oils may be added in a state where hydration is not completed in some parts of the dough, and only fats and oils are combined with flour in some places and dartene is missing in some places. On the other hand, in the method of the present invention, it is a matter of course that a much denser dartene structure is produced evenly than before.
[0110] さらに、最高品質のパンの製造を目指し、攪拌混合をあくまで避けたい場合は、乳 化装置を使って予め水と混合しておくことが好ましい。本発明の製造方法では水滴 粒子が小麦粉に対して均一に行き渡るために、油脂によるダルテン生成の妨害は生 じにくい。  [0110] Furthermore, when aiming at the production of the highest quality bread and wanting to avoid stirring and mixing, it is preferable to preliminarily mix with water using an emulsifying device. In the production method of the present invention, the water droplet particles are uniformly distributed over the wheat flour, so that the obstruction of the production of dartene by fats and oils is unlikely to occur.
[0111] 従って、乳化さえしておけば、油脂の混合を水和と同時に行うことができる。後工程 での油脂添加と攪拌混合は不要になり、ダルテンの網目組織破壊を完全に避けるこ とがでさる。  [0111] Therefore, as long as emulsification is performed, the fats and oils can be mixed simultaneously with hydration. Oil and fat addition and stirring and mixing are not necessary in the post-process, and Darten network structure destruction can be completely avoided.
[0112] 本発明の製パン方法では、水分添加のためのミキシング工程と、ダルテンの網目組 織を発達されるための練り工程を完全に分離できる。そして、ミキシング工程と練りェ 程をそれぞれ最適な条件で行うことが可能になる。したがって、従来にない美味しさ や食感が得られるパン作りが可能になった。  [0112] In the bread-making method of the present invention, the mixing step for adding water and the kneading step for developing a dartene network can be completely separated. The mixing process and the kneading process can be performed under optimum conditions. Therefore, it has become possible to make bread that has an unprecedented taste and texture.
[0113] パンの美味しさを左右するのは、クラム (パンの中身)の肌目細力さや弾力、クラスト  [0113] The deliciousness of bread is influenced by the fineness and elasticity of crumb (bread contents), crust.
(表面)のパリパリ感と薄さである。これらはダルテンの網目組織の緻密さに影響され るものである。  (Surface) Crisp and thin. These are influenced by the denseness of the darten network.
[0114] 緻密なダルテンの網目組織を作るポイントは、いかにして全ての小麦粉粒子に等し い割合で水分を与えるかである。換言すれば、ミキシングのミクロ的な均一性をいか に実現するかが高品質のパン作りにおける重要な課題である。  [0114] The point of creating a fine Dalten network is how to give moisture to all flour particles in an equal proportion. In other words, how to achieve the microscopic uniformity of mixing is an important issue in producing high-quality bread.
[0115] 従来の製法ではダルテンの網目組織破壊がネックになって、ミクロ的な均一性を求 めるのは不可能であった。し力しながら、本発明による製パン法においては、ミキシン グの当初力 各小麦粉粒子に微粒の水滴を添付できるので、ダルテン生成はミクロ 的に見ても均一になされる。 [0116] したがって、その後の簡単な練りによって網目糸且織もこの上なく緻密になり、イースト 発酵時に発生するガスは小さな網目の中に閉じ込められて細かい気泡がむら無く生 成される。従って、焼き上がったパンは肌目細力べ弾力に富んだクラムを持ち、クラス トも薄くてノ《リツとしたものになる。 [0115] In the conventional manufacturing method, disruption of the network structure of Dalten was a bottleneck, and it was impossible to obtain microscopic uniformity. However, in the bread-making method according to the present invention, since the initial force of mixing can be attached with fine water droplets to each flour particle, the generation of dartene is made uniform even when viewed microscopically. [0116] Thus, the subsequent kneading makes the mesh yarn and weave as fine as possible, and the gas generated during the yeast fermentation is trapped in the small mesh and fine bubbles are uniformly generated. Therefore, the baked bread has a crumb that is rich in skin and elasticity, and the crust is thin and crisp.
[0117] 次に、製麵について述べる。一般に工業的な製麵においては、切歯ロールを用い て規定の断面形状 ·寸法を持つ麵を圧延成形するが、このとき問題になるのは生地 が切り歯ロールに粘着するトラブルである。このトラブルは生地に水分が均一に行き 渡っていない場合に生じやすい。なぜなら、生地中に過剰な水分を抱く箇所が無数 に生じ、その部分で粘着が生じるからである。  [0117] Next, ironmaking will be described. In general, in an industrial iron making, an incisor roll is used to roll and form an iron having a prescribed cross-sectional shape and dimensions. At this time, the problem is a problem that the fabric adheres to the incision roll. This problem is likely to occur when moisture is not evenly distributed in the dough. This is because there are innumerable places that have excessive moisture in the dough, and sticking occurs in those areas.
[0118] 従来法では、水分の完全均一化が難 、ので、やむを得ず加水率を下げて!/、る。 [0118] In the conventional method, it is difficult to completely homogenize the water, so the water content is unavoidably lowered!
一方、本発明による製造方法では、生地全体にむら無く水分が行き渡り、過剰な水 分を抱いた部分が無いので、従来よりもおよそ 10%以上加水率を増やすことができ る。  On the other hand, in the production method according to the present invention, moisture is uniformly distributed throughout the dough, and there is no portion that has excessive water content. Therefore, the water content can be increased by about 10% or more compared to the conventional method.
[0119] 加水率が高ければ麵の加工も楽になり、練りによって生じる応力が減るので、網目 組織の破壊を防ぎながらダルテンの組織を望まし!/、形態に発達させることが容易に なる。例えばそうめんの場合、従来は手述べ法などの手間が掛カる手段でダルテン の組織をしつかりと長手方向に発達させることによって、つるつるした喉越しの良い味 覚を得ている。  [0119] The higher the water content, the easier the processing of the koji and the less the stress caused by kneading, and the easier it is to develop the desired Darten structure while preventing the destruction of the network structure! For example, in the case of somen noodles, in the past, the darten tissue was developed in the longitudinal direction by means of time-consuming methods such as the handwriting method, thereby obtaining a smooth taste over the throat.
[0120] 一方、本発明による混合によってダルテンを生地全体に緻密に生成させておけば、 後工程の簡素な圧延装置でそれを長手方向に発達させることは容易になり、高級品 を低コストで生産することが可能になる。  [0120] On the other hand, if the dartene is densely formed on the entire dough by mixing according to the present invention, it becomes easy to develop it in the longitudinal direction with a simple rolling device in the subsequent process, and a high-quality product can be produced at low cost. It becomes possible to produce.
[0121] その他にも加水率が高 、ことは様々なメリットがある。打ち立ての麵では、含まれて いる水分が麵生地中の澱粉の α化に必要な量 (澱粉の約 60%)に近くなる。そのた め、不足水分が麵の表面から浸透するのを待つ時間が減り、茹で時間が短縮される  [0121] In addition, high water content has various advantages. In freshly cooked rice cake, the water content is close to the amount required for pre-gelatinizing starch in the koji dough (about 60% of starch). Therefore, the time to wait for insufficient moisture to permeate from the surface of the cocoon is reduced, and the time is shortened with the cocoon.
[0122] 乾麵では乾燥後の麵がポーラスになって水分の浸透が早くなり、やはり茹で時間が 短縮される。茹で時間を短縮できれば、麵本来の持つうまみや香りが茹でる湯へ溶 出するのを減じることができる。また、長く茹でると表面にぬめりが生じる力 それを抑 えることもでき、食感が改善される。しカゝも、茹でるためのエネルギーや時間を節約で きる。 [0122] In dry rice cake, the dried rice cake becomes porous and moisture permeates faster. If the time can be shortened with boil, it is possible to reduce the umami and aroma inherent in the boil from melting into the boiling water. Also, if you boil it for a long time, the force that causes slime on the surface will be suppressed. The texture is also improved. Shika also saves energy and time for cooking.
[0123] 以上の説明で明らかなように、本発明の装置に粉体原料および液体原料を供給し 、粉体回転盤 10上を径の大きい方向へ流れる粉体層に対し、粉体回転盤 10の中央 部から外周縁部にかけての部分の位置 (混合部 71)にて粉体と同程度の大きさの直 径を持つ液体粒子を放射させ衝突させる。そうすると、個々の粉体粒子に対して液体 粒子が添付される結果、ほぼ完全に均一な混合が連続して得られる。  As is apparent from the above description, the powder raw material and the liquid raw material are supplied to the apparatus of the present invention, and the powder rotating disk is used for the powder layer that flows on the powder rotating disk 10 in the direction of large diameter. Liquid particles having a diameter of the same size as that of the powder are radiated and collided at the position (mixing section 71) from the center of the 10 to the outer peripheral edge. As a result, liquid particles are attached to the individual powder particles, and as a result, almost completely uniform mixing is continuously obtained.
[0124] 粉体回転盤 10の混合部 71付近にて、粉体回転盤 10の上面形状を断面形状で昇 り坂を成す形状 (テーパー形状)、すなわち、すり鉢状とすることにより、或いは混合を 加速させたい箇所の断面形状を凹面状にすることにより、粉体粒子層に活発な上下 層の入れ替え運動を喚起させることができる。  [0124] In the vicinity of the mixing portion 71 of the powder turntable 10, the top surface shape of the powder turntable 10 is an uphill with a cross-sectional shape (taper shape), that is, a mortar shape or mixing. By making the cross-sectional shape of the portion where the acceleration is desired to be concave, it is possible to provoke active movement of upper and lower layers in the powder particle layer.
[0125] すなわち、遠心力の差を利用して分級をするサイクロンと同じ作用が働いて、液体 添付が少ない粒子は表層に浮かび上がり、添付が多い粒子は深層に沈む。そして 表層の添付不足粒子に対し選択的に液体粒子添付が行われる。  That is, the same action as a cyclone that classifies using the difference in centrifugal force works, particles with little liquid attachment appear on the surface, and particles with much attachment sink in the deep layer. Then, liquid particles are selectively attached to the insufficiently attached particles on the surface layer.
[0126] カゝくして粉体粒子群はミクロ的にもほぼ均一な割合で液体粒子群と混合し、理想的 な混合が完成する。  [0126] The powder particles are mixed with the liquid particles at an approximately uniform ratio even on a microscopic scale, and ideal mixing is completed.
以上より、本発明の実施形態によれば、次のことが実現できる。まず、発明による混 合装置 100に粉体原料を投入する。そうすると、粉体原料は、スクリューフィーダ一 4 によって粉体回転盤 10の中心上にある粉体受け部 16aに導かれ、回転力を受けて 粉体受け部 16aから流出する際に凝集塊破砕歯 17によってバラバラの粒子になる。  As described above, according to the embodiment of the present invention, the following can be realized. First, the powder raw material is put into the mixing apparatus 100 according to the invention. Then, the powder raw material is guided by the screw feeder 4 to the powder receiving portion 16a located on the center of the powder rotating disk 10, and receives the rotational force and flows out of the powder receiving portion 16a. By 17 it becomes a piece of particles.
[0127] その後、粉体回転盤 10から再び回転力を与えられて、粉体原料は粉体回転盤 10 の径の大きい方へ移動しょうとする。このとき、スクリューフィーダ一 4の静止するケー シング 5の下端部に取付けられた粉体分散カップ 18によって粉体の運動が制限され 、粉体分散カップ 18と粉体回転盤 10との小さな隙間 70から粉体原料が流出する。  Thereafter, a rotational force is applied again from the powder rotating disk 10, and the powder raw material tries to move toward the larger diameter of the powder rotating disk 10. At this time, the movement of the powder is restricted by the powder dispersion cup 18 attached to the lower end of the casing 5 where the screw feeder 4 is stationary, and a small gap 70 between the powder dispersion cup 18 and the powder rotating disk 10 is obtained. Powder raw material flows out from.
[0128] その粉体原料の流出量は 360度全方向に均一で、変動もしない。なぜなら、凝集 塊破砕歯 17が予め粉体をばらばらの粒子群にしてあること、および粉体分散カップ 1 8が回転していないために粉体回転盤 10との狭い隙間(粉体受け部 72)〖こ挟まれた 粉体には周方向の流動が与えられていることが、効果を発揮するからである。 [0129] また、混合部 71で、噴霧器 22 (または 61)より放射された液体原料と、隙間 70より 放出された粉体原料とが、衝突して混合する。混合部 71を経て粉体回転盤 10の外 周部に達し放射された混合物は、混合物反射体 51に衝突する。 [0128] The outflow amount of the powder raw material is uniform in all directions of 360 degrees and does not fluctuate. This is because the agglomerate crushing teeth 17 have previously divided the powder into a group of particles, and the powder dispersion cup 18 is not rotating, so that there is a narrow gap between the powder rotating disk 10 (powder receiving portion 72). This is because it is effective that a circumferential flow is given to the sandwiched powder. [0129] Further, in the mixing unit 71, the liquid raw material emitted from the sprayer 22 (or 61) and the powder raw material released from the gap 70 collide and mix. The mixture radiated through the mixing unit 71 and reaching the outer periphery of the powder rotating disk 10 collides with the mixture reflector 51.
[0130] 混合物反射体 51に衝突した後、その混合物 80は低速で回転する混合物受け 52 上に落下堆積する。その落下堆積した混合物 80は、混合物排出スクレーバ 59、混 合物排出シュート 60によって装置外に連続的に排出され、コンベア等にて次工程へ 送られる。  [0130] After impinging on the mixture reflector 51, the mixture 80 falls and deposits on the mixture receiver 52 rotating at low speed. The fallen and deposited mixture 80 is continuously discharged out of the apparatus by the mixture discharge scraper 59 and the mixture discharge chute 60 and sent to the next process by a conveyor or the like.
[0131] 混合物が固体への粘着性を持つ場合、混合物が接触する箇所に弗素化合物など の非粘着性物質をコーティングしてもよい。また、静止している部品であれば、混合 物が接触する箇所に振動を加えて、その混合物をその接着面より除去するようにして もよい。或いは小麦粉製品の場合であれば、混合物が接触する箇所に対して、 120 °C〜 140°Cに加熱するなどの手段を講じればよい。  [0131] When the mixture has adhesiveness to a solid, a non-adhesive substance such as a fluorine compound may be coated at a position where the mixture comes into contact. In addition, if it is a stationary part, vibration may be applied to the place where the mixture contacts, and the mixture may be removed from the adhesive surface. Alternatively, in the case of flour products, measures such as heating to 120 ° C. to 140 ° C. may be taken for the place where the mixture contacts.
[0132] 以上より、本発明によれば、粉体原料と液体原料とを定量供給すれば、両者の混 合物を一定量ずつ連続して取り出すことができる。また、混合装置内に原料が滞留 する空間が小さいため、少量生産時の原料の無駄を少なく抑えることができる。また、 本発明にかかる混合装置は、大きな処理能力を持つ割には小型であり、分解掃除も 容易である。  [0132] As described above, according to the present invention, if a powder raw material and a liquid raw material are supplied in a fixed amount, a mixture of both can be continuously taken out by a fixed amount. In addition, since the space in which the raw material stays in the mixing device is small, it is possible to reduce the waste of the raw material when producing a small amount. In addition, the mixing apparatus according to the present invention is small for having a large processing capacity, and is easy to disassemble and clean.
[0133] また、粉体原料が小麦粉で液体原料が主に水である場合、混合物を高品質な製品 に仕上ることが容易にできる。すなわち、ダルテンが既に生地全体に緻密に生成され て 、るので、軽 、手捏ねや簡素な圧延装置などの純粋な練り工程で処理することに よって、望みの形態のダルテン網目組織を容易に形成させることができる。  [0133] Further, when the powder raw material is wheat flour and the liquid raw material is mainly water, the mixture can be easily finished into a high-quality product. In other words, since dartene has already been densely formed throughout the dough, it can be easily formed into a dartene network of the desired form by processing in a pure kneading process such as a light kneading or a simple rolling mill. Can be made.
[0134] また、本発明にかかる混合装置を用いることにより、従来必要であった混練、圧延、 寝力しなどの設備、スペース、時間や労力は大幅に節約され、経済的にも優れた製 造工程を実現できる。  [0134] Further, by using the mixing apparatus according to the present invention, facilities, space, time, and labor such as kneading, rolling, and bedding that have been required in the past are greatly saved, and an economically excellent production is achieved. The manufacturing process can be realized.
[0135] また、本発明にかかる混合装置を使う製法によって、従来にない豊カな味と食感を 持つ高品質なパン類ゃ麵製品を、短縮された工程で、低コストにて生産することが可 能になる。また、臭素酸カリウムのような問題ある添加物の使用も不要になる。  [0135] Also, by using the manufacturing method using the mixing apparatus according to the present invention, a high-quality bread candy product having an unprecedented rich taste and texture is produced at a low cost with a shortened process. It becomes possible. Also, the use of problematic additives such as potassium bromate is eliminated.
[0136] また、麵製品の場合は加水率を大幅に高めることができるので、茹で時間を短縮で きる。それに伴って食感を含む味覚の向上、エネルギーや時間の節約などのメリット が得られ、魅力ある製品の生産が可能になる。 [0136] In addition, in the case of rice bran products, the water content can be greatly increased, so the time required for cooking can be reduced. wear. Along with this, benefits such as improved taste, including texture, and energy and time savings can be obtained, making it possible to produce attractive products.
また、攪拌混合や長時間の処理を嫌う薬品、工業原料の混合においても本発明に 力かる混合装置を利用する価値が高い。  In addition, it is highly valuable to use a mixing apparatus that is effective in the present invention for mixing chemicals and industrial raw materials that do not require stirring and mixing for a long time.
なお、本発明は、以上に述べた実施の形態に限定されるものではなぐ本発明の要 旨を逸脱しない範囲内で種々の構成または実施形態を取ることができる。  It should be noted that the present invention is not limited to the embodiments described above, and can take various configurations or embodiments without departing from the scope of the present invention.
