  • the rice grains 8 pressed against the side wall rise along the side wall.
  • the rice grain 8 rising on the side wall rises to a predetermined height of the container 2 due to the balance between the increasing component of the force applied to the rice grain 8 and the weight of the rice grain 8. Then, when the rice grain 8 reaches a predetermined height, the weight of the rice grain 8 becomes larger than the increasing component of the force given to the rice grain 8, and as shown in FIG. It falls almost toward the center of the bottom.

  • Such a conventional rice washer having a rice milling function has the following problems. Agitating water and rice grains using mechanical force tends to damage the rice grains, and water mixed with bran cannot be quickly separated from the rice grains. For this reason, the rice grains absorb the water with a rice bran odor, and the cooked rice becomes rice with a rice odor, and the fatty acids contained in the rice bran are oxidized to increase the heat retention odor.
  • Unwashed rice which uses water in the manufacturing process, is inferior in taste because it is washed with water and then distributed in a dry state.
  • Non-washed rice using sticky bran has a problem that the system is not easy to handle because the system is very large and the use of bran is not easy.
  • a rice washing machine 50 having a rice-milling function has been developed as one of the purposes for removing bran 9 from brown rice.
  • the power he gives to brown rice is powerful. Therefore, if white rice is introduced into the rice washer 50 and used to remove the bran 9 on the surface of the white rice, the power of the rice washer 50 system applied to the rice grains will increase the removal of the bran 9 on the surface. Is too strong and can damage starch cells on rice grain surface.

  • the force of raising the side wall more than the own weight of the rice grains 8 depends on the input amount of the rice grains 8 and the rotation speed of the rotating blades 4.
  • the rice grains 8 are not pressed up on the side wall of the container 2 and do not rise on the side wall or fall to the substantially bottom center of the container 2.
  • the circulation of the rice grains 8 is not performed efficiently, and the rice grains 8 that are excessively rubbed and damage the starch cells are generated, or the rice grains 8 that cannot sufficiently separate the bran 9 are generated. Therefore, there is a problem that unevenness occurs in the washing of rice.

Description

明 細 書 洗 米 器 技術分野  Technical Manual Washing Riceware
本発明は、 洗米器に関するものである。 背景技術  The present invention relates to a rice washing machine. Background art
従来、 洗米工程を自動化し省力化を図る機器が多数開発されている。 代表的な ものとして、 機械力を用いて水と米粒を攪拌させるもの、 流水の中で米粒同士を 水圧により擦り合わせるものがある。  Conventionally, many devices have been developed to automate the rice washing process and save labor. Typical examples include a method in which water and rice grains are agitated by using mechanical force, and a method in which rice grains are rubbed by flowing water in running water.
また、 糠を取り除いた状態で販売されている無洗米もある。  There are also non-washed rice sold without the bran.
従来の精米機能を備えた洗米器として、 図 4 2に示す構成のもの (例:特開平 1 1 - 1 9 7 5 2 1号公報) がある。 ここでは図 4 2に示す洗米器の構成につい て説明する。  As a conventional rice-washing machine having a rice-milling function, there is a rice-washing machine having a configuration shown in FIG. Here, the configuration of the rice washer shown in Fig. 42 will be described.
図 4 2に示すように、 この洗米器 5 0においては、 内部に米を収納する略カツ プ状の容器 2を設けている。 また、 容器 2の側壁は金網等で構成されていて、 そ れには米粒を選択的に通過させない大きさの孔 3が形成されている。 そして、 容 器 2の内部に回転羽根 4を設けている。 そして、 容器 2の下面に回転羽根 4を駆 動するための駆動手段 5を設けている。 制御手段 6は駆動手段 5を制御するとと もに精米工程を制御するように構成している。 さらに、 洗米器蓋 7がある。 図 4 3を用いて、 従来の洗米器の動作を説明する。 利用者が略カップ状の容器 2内に所定量の米粒 8を投入し、 洗米器蓋 7を洗米器 5 0に取り付けた後運転を 開始すると、 制御手段 6により駆動手段 5が動作する。  As shown in FIG. 42, the rice washer 50 has a substantially cup-shaped container 2 for storing rice therein. Further, the side wall of the container 2 is made of a wire mesh or the like, and a hole 3 having a size that does not allow rice grains to selectively pass therethrough is formed therein. The rotating blades 4 are provided inside the container 2. Further, a driving means 5 for driving the rotating blades 4 is provided on the lower surface of the container 2. The control means 6 is configured to control the driving means 5 and also control the rice polishing process. In addition, there is a rice washing lid 7. The operation of the conventional rice washer will be described with reference to FIGS. When the user puts a predetermined amount of rice grains 8 into the substantially cup-shaped container 2, attaches the rice washing machine lid 7 to the rice washing machine 50, and starts the operation, the control means 6 operates the driving means 5.
駆動手段 5が動作すると回転羽根 4が回転するので、 略円筒容器 2内に収納さ れた米粒 8が攪拌される。 When the driving means 5 operates, the rotating blades 4 rotate, so that the rotating blades 4 are stored in the substantially cylindrical container 2. Rice grains 8 are stirred.
回転羽根 4により攪拌される米粒 8は、 回転羽根 4による押し付け力と遠心力 により容器 2の側壁へ押し付けられる。  The rice grains 8 stirred by the rotating blades 4 are pressed against the side wall of the container 2 by the pressing force and the centrifugal force of the rotating blades 4.
側壁へ押し付けられた米粒 8は容器 2の側壁に形成された孔 3に擦り付けられ たり、 米粒 8同士が衝突したりするので、 米粒 8の表面の糠 9が削り取られるこ とになる。 そして、 削り取られた糠 9や米粒 8の中に混在するごみや虫等が孔 3 から容器 2外へ排出される。  The rice grains 8 pressed against the side walls are rubbed against the holes 3 formed in the side walls of the container 2 or the rice grains 8 collide with each other, so that the bran 9 on the surface of the rice grains 8 is scraped off. Then, garbage and insects mixed in the shaved bran 9 and the rice grains 8 are discharged from the hole 3 to the outside of the container 2.
また、 米粒 8は、 回転羽根 4により次々に容器 2の側壁へ押し付けられる。 側 壁に押し付けられた米粒 8は、 側壁に沿って上昇していく。 側壁を上昇する米粒 8は、 米粒 8に与えられた力の上昇成分と米粒 8の自重とのバランスにより、 容 器 2の所定の高さにまで上昇する。 そして、 所定の高さに達すると、 米粒 8の自 重の方が、 米粒 8に与えられた力の上昇成分よりも大きくなるので、 図 4 3に示 すように、 米粒 8は容器 2の略底部中央に向かって落下していく。  The rice grains 8 are successively pressed against the side walls of the container 2 by the rotating blades 4. The rice grains 8 pressed against the side wall rise along the side wall. The rice grain 8 rising on the side wall rises to a predetermined height of the container 2 due to the balance between the increasing component of the force applied to the rice grain 8 and the weight of the rice grain 8. Then, when the rice grain 8 reaches a predetermined height, the weight of the rice grain 8 becomes larger than the increasing component of the force given to the rice grain 8, and as shown in FIG. It falls almost toward the center of the bottom.
落下した米粒 8は、 回転羽根 4により容器 2の側壁に押し付けられて容器 2の 側壁を上昇し、 糠 9やごみ、 虫等が分離され、 再び容器 2の略底部中央に落下す るという循環を繰り返す。 そして、 米粒 8は均一に精白されていく。  The fallen rice grains 8 are pressed against the side walls of the container 2 by the rotating blades 4 and rise up the side walls of the container 2, whereby the bran 9, garbage, insects, etc. are separated, and fall again to the substantially bottom center of the container 2. repeat. Then, the rice grains 8 are uniformly refined.
所定の時間が経過した後、 制御手段 6は駆動手段 5を停止させて運転を終了す る。  After a predetermined time has elapsed, the control means 6 stops the drive means 5 and ends the operation.
このような従来の構成の精米機能を備えた洗米器では以下の問題を有している。 機械力を用いて水と米粒を攪拌させるものは米粒を傷つけやすく、 また糠の混 合した水を素早く米粒と分離することができない。 このため、 糠臭のする水を米 粒が吸収し、 炊飯した米飯が糠臭いご飯となり、 さらには糠に含まれる脂肪酸が 酸化し保温臭を増大させてしまう。  Such a conventional rice washer having a rice milling function has the following problems. Agitating water and rice grains using mechanical force tends to damage the rice grains, and water mixed with bran cannot be quickly separated from the rice grains. For this reason, the rice grains absorb the water with a rice bran odor, and the cooked rice becomes rice with a rice odor, and the fatty acids contained in the rice bran are oxidized to increase the heat retention odor.
また、 流水の中で米粒同士を水圧により擦り合わせるものは大量の水を必要と する。 また、 糠を取り除いた状態で販売されている無洗米については二つの製法があ る。 製造工程で水を用いる無洗米では、 水を用いて洗浄した後、 乾燥させた状態 で流通させるために、 食味が劣る。 粘着質の糠を用いる無洗米は、 システムが非 常に大規模でかつ糠を用いることもあってその取り扱いが容易ではなく、 システ ムを簡単な構成とすることができないという問題がある。 In addition, a large amount of water is required for running water that rubs rice grains by water pressure. In addition, there are two production methods for unwashed rice sold without bran. Unwashed rice, which uses water in the manufacturing process, is inferior in taste because it is washed with water and then distributed in a dry state. Non-washed rice using sticky bran has a problem that the system is not easy to handle because the system is very large and the use of bran is not easy.
さらに、 図 4 2および図 4 3に示すような、 精米機能をもつ洗米器 5 0は、 玄 米から糠 9を除去することもその目的の一つとして開発されているもので、 回転 羽根 4が玄米に与える力は強力なものである。 そのため、 白米を洗米器 5 0に投 入して白米の表面の糠 9を除去するために用いると、 洗米器 5 0のシステムが米 粒に与える力は、 その表面の糠 9を除去するには強力すぎて、 米粒表面の澱粉細 胞を傷つけてしまうおそれが大きい。  Further, as shown in FIGS. 42 and 43, a rice washing machine 50 having a rice-milling function has been developed as one of the purposes for removing bran 9 from brown rice. The power he gives to brown rice is powerful. Therefore, if white rice is introduced into the rice washer 50 and used to remove the bran 9 on the surface of the white rice, the power of the rice washer 50 system applied to the rice grains will increase the removal of the bran 9 on the surface. Is too strong and can damage starch cells on rice grain surface.
それゆえ、 炊飯時に澱粉の流出を招き易ぐ 炊飯した米飯がベたつく等、 物性 を損ない食味への悪影響を生じることになる。  Therefore, it is easy to cause the starch to flow out during cooking, and the cooked rice sticks, and the physical properties are impaired, and the taste is adversely affected.
また、 図 4 3に示すように、 容器 2の側壁を上昇した米粒 8は、 容器 2の側壁 部分から落下してくるため、 容器 2の略底部中央へ向かって落下しない場合もあ る。  Further, as shown in FIG. 43, the rice grains 8 that have risen on the side wall of the container 2 fall from the side wall portion of the container 2 and may not fall toward the substantially bottom center of the container 2 in some cases.
さらに、容器 2の側壁を上昇した米粒 8は、その自重のみで落下してくるので、 米粒 8の投入量や回転羽根 4の回転数等により、 米粒 8の自重よりも側壁を上昇 する力の成分の方が常に大きい場合は、 図 4 4に示すように、 米粒 8が容器 2の 側壁に押し付けられたまま、 側壁を上昇しなくなったり、 容器 2の略底部中央に 落下しなくなったりする。 そのため、 米粒 8の循環が効率的に行われず、 擦りつ けすぎて澱粉細胞を傷つけすぎた米粒 8が生じたり、 糠 9を十分に分離できない 米粒 8が生じたりする。それゆえ、洗米にムラが生じてしまうという問題もある。 これらの問題を解決するために、 回転羽根 4の作用により米粒 8が容器 2内で 循環する際に生じる米粒 8同士の擦り合わせにより、 米粒 8の表面の糠 9を削り 取るという洗米器が提案されている。 Further, since the rice grains 8 that have risen on the side wall of the container 2 fall only by their own weight, the force of raising the side wall more than the own weight of the rice grains 8 depends on the input amount of the rice grains 8 and the rotation speed of the rotating blades 4. When the component is always larger, as shown in FIG. 44, the rice grains 8 are not pressed up on the side wall of the container 2 and do not rise on the side wall or fall to the substantially bottom center of the container 2. As a result, the circulation of the rice grains 8 is not performed efficiently, and the rice grains 8 that are excessively rubbed and damage the starch cells are generated, or the rice grains 8 that cannot sufficiently separate the bran 9 are generated. Therefore, there is a problem that unevenness occurs in the washing of rice. In order to solve these problems, the rotating blades 4 rub the rice grains 8 generated when the rice grains 8 circulate in the container 2, thereby shaving off the bran 9 on the surface of the rice grains 8. A rice washer has been proposed to be taken.
この構成の洗米器においては、 米粒 8同士の擦り合わせのみで米粒 8の表面の 糠 9を削り取るので、 米粒 8を擦りつけすぎて米粒 8の澱粉細胞を傷つけすぎる という問題を低減することができる。  In the rice washer of this configuration, the bran 9 on the surface of the rice grain 8 is scraped off only by rubbing the rice grains 8 together, so that the problem of excessively rubbing the rice grains 8 and damaging the starch cells of the rice grains 8 too much can be reduced. .
しかしながら、 この構成においても、 上記に述べた洗米器 5 0と同様、 図 4 3 と図 4 4に示すように、 米粒 8が効率的に循環されずに洗米にムラが生じたり、 米粒 8を洗米するのに多くの時間を有したりするという問題を有する。  However, even in this configuration, similarly to the rice washing machine 50 described above, as shown in FIGS. 43 and 44, the rice grains 8 are not efficiently circulated, causing unevenness in the rice washing, There is a problem that a lot of time is required for washing rice.
本発明は上記従来の課題を解決するもので、 米粒を効率的に循環させて米粒の 澱粉細胞を傷つけることなく、 米粒の表面から糠を分離でき、 また洗米時間を短 縮した洗米器を提供することを目的としている。 発明の開示  The present invention solves the above-mentioned conventional problems, and provides a rice washer capable of efficiently circulating rice grains and separating rice bran from the surface of the rice grains without damaging the starch cells of the rice grains and shortening the rice washing time. It is intended to be. Disclosure of the invention

It has a container lid. The rotating blades raise the rice grains to the container side wall or the container lid while pressing the rice grains against the upper side wall of the container, and the container side wall or the container lid has a specific structure to move the rising rice grains to the approximate center of the container. It has the structure which has. If necessary, a part of the side periphery of the container is provided with a partition having an opening for selectively preventing rice grains from passing therethrough.
また、 本発明の洗米器は、 回転羽根を回転させる遠心力により米粒を回転羽根 の上端まで上昇させた後、 自由落下させる循環を繰り返す。 回転羽根の表面には 必要によりブラシが形成されている。  In addition, the rice washer of the present invention repeats circulation in which rice grains are lifted to the upper end of the rotating blade by centrifugal force for rotating the rotating blade, and then fall freely. A brush is formed on the surface of the rotating blade as necessary.
さらに、 本発明の洗米器の制御手段は、 洗米工程中に回転羽根の回転数が変化 するように駆動手段を制御するように構成したものである。  Further, the control means of the rice washing machine of the present invention is configured to control the driving means so that the rotation speed of the rotating blades changes during the rice washing process.

BEST MODE FOR CARRYING OUT THE INVENTION
以下、 本発明の実施例 1について、 図面を参照しながら説明する。 なお、 従来 例における構成要素と対応する要素には同じ符号を付している。 (実施例 1 )  Hereinafter, Embodiment 1 of the present invention will be described with reference to the drawings. Elements corresponding to the constituent elements in the conventional example are denoted by the same reference numerals. (Example 1)
図 1に示す洗米器 5 0は形状がほぼコップ状の容器 1 1を備えており、 容器 1 1は米粒を収納することができる。 また、 容器 1 1の上部には、 容器 1 1内に米 粒 8を密閉するように容器蓋 1 2が備えられている。 また、 回転羽根 4は、 容器 1 1内に配設され、 駆動手段 5により回転する。  The rice washing machine 50 shown in FIG. 1 includes a container 11 having a substantially cup shape, and the container 11 can store rice grains. Further, a container lid 12 is provided at an upper portion of the container 11 so as to seal the rice grains 8 in the container 11. The rotating blades 4 are arranged in the container 11 and are rotated by the driving means 5.
上記構成において、 図 2により動作を説明する。 所定量の米粒 8を容器 1 1内 に投入し、 蓋 1 2を取り付ける。 蓋 1 2を取り付けて米粒 8を容器 1 1内に密閉 した後、 運転を開始する。 The operation of the above configuration will be described with reference to FIG. Predetermined amount of rice grains 8 in container 1 1 And attach the lid 1 and 2. After the lid 12 is attached and the rice grains 8 are sealed in the container 11, the operation is started.
運転が開始されると、 制御手段 6により駆動手段 5が動作して回転羽根 4が回 転する。 そして、 回転羽根 4が米粒 8に押し付け力を与えるとともに、 回転羽根 4の回転により米粒 8には容器 1 1の側壁へ向かう遠心力が発生する。 それによ つて米粒 8が次々に容器 1 1の側壁へ向かって移動し、 さらに米粒 8が容器 1 1 の側壁を上昇する。 ,  When the operation is started, the driving means 5 is operated by the control means 6, and the rotating blades 4 are rotated. The rotating blades 4 apply a pressing force to the rice grains 8, and the rotation of the rotating blades 4 generates a centrifugal force in the rice grains 8 toward the side wall of the container 11. As a result, the rice grains 8 move one after another toward the side wall of the container 11, and the rice grains 8 further rise up the side wall of the container 11. ,
容器 1 1の上部には蓋 1 2が配置されているので、 容器 1 1の側壁を上昇した 米粒 8は、 図 2 ( a) に示すように、 蓋 1 2と衝突し、 さらに蓋 1 2の内面に沿 つて容器 1 1の略中央部に向かうことになる。 米粒 8が略中央部近傍に近づくに 従って、 米粒 8に作用する遠心力が減少し、 米粒 8に与えられる力は重力のみに なる。 そのため、 米粒 8は自重により容器 1 1の略中央部から底部へ向かって落 下する。 '  Since the lid 12 is placed on the upper part of the container 11, the rice grains 8 rising on the side wall of the container 11 collide with the lid 12 as shown in FIG. Along the inner surface of the container 11 toward the approximate center of the container 11. As the rice grains 8 approach the vicinity of the center, the centrifugal force acting on the rice grains 8 decreases, and the force given to the rice grains 8 is only gravity. Therefore, the rice grains 8 fall from the substantially central portion of the container 11 toward the bottom by its own weight. '
このように本実施例によれば、 蓋 1 2が米粒 8の容器 1 1の側壁を上昇する力 の成分を、 容器 1 1の中央部へ向きを変更させる。 このため、 米粒 8は容器 1 1 の側壁を上昇するだけでなく、 蓋 1 2に沿って容器 1 1の略中央部に向かって移 動し、 さらに略中央部から底部へ落下していく。 このように、 容器 1 1内で米粒 8を効率的に循環させることができる。 すなわち、 米粒の循環流れを効率的に生 み出すことができるので、 米粒 8同士を擦り合わせて米粒 8の表面の糠を削り取 るという洗米能力を向上させることができる。  As described above, according to the present embodiment, the lid 12 changes the direction of the component of the force for raising the side wall of the container 11 of the rice grains 8 toward the center of the container 11. Therefore, the rice grains 8 not only move up the side wall of the container 11, but also move along the lid 12 toward the substantially central portion of the container 11, and further fall from the substantially central portion to the bottom. Thus, the rice grains 8 can be efficiently circulated in the container 11. That is, the circulating flow of the rice grains can be efficiently generated, so that the rice washing ability of rubbing the rice grains 8 to scrape off the bran on the surface of the rice grains 8 can be improved.
なお、 図 2 ( b) に示すように、 容器 1 1の上部が蓋 1 2の一部を形成するよ うに構成されてもよい。 また、 図 2 ( c ) に示すように、 蓋 1 2が、 容器 1 1の 側壁の一部を形成するように構成されてもよい。 また、 容器 1 1の側壁には米粒 8を選択的に通過させない寸法の孔を形成しておいてもよい。 (実施例 2 ) In addition, as shown in FIG. 2B, the upper portion of the container 11 may be configured to form a part of the lid 12. Further, as shown in FIG. 2C, the lid 12 may be configured to form a part of the side wall of the container 11. Further, a hole having a size that does not allow the rice grains 8 to selectively pass therethrough may be formed in the side wall of the container 11. (Example 2)
本実施例の洗米器は、 図 3 ) に示すように、 蓋 1 2はほぼドーム状の形状 に形成されている。 他の構成は上記実施例 1と'同じである。  In the rice washer of this embodiment, as shown in FIG. 3), the lid 12 is formed in a substantially dome shape. Other configurations are the same as those in the first embodiment.
上記構成において、 動作を説明する。 回転羽根 4を動作させると回転羽根 4の 押し付け力と遠心力により米粒 8が容器 1 1の側壁を上昇する。  The operation of the above configuration will be described. When the rotating blades 4 are operated, the rice grains 8 rise on the side wall of the container 11 due to the pressing force and the centrifugal force of the rotating blades 4.
このとき、 図 3 ( b) に示すように、 蓋 1 2が平坦に形成されている場合は、 容器 1 1と蓋 1 2との接続部で滞留する米粒 8 aが発生する可能性がある。 これ に対し、 図 3 ( a) に示すように、 盖 1 2の形状をドーム状とすることにより、 容器 1 1と蓋 1 2との接続部で米粒 8を滞留させることなく、 側壁を上昇してき たすベての米粒 8を確実に容器 1 1の略底部中央へ案内することができる。  At this time, as shown in FIG. 3 (b), if the lid 12 is formed flat, there is a possibility that rice grains 8a staying at the connection between the container 11 and the lid 12 will be generated. . On the other hand, as shown in Fig. 3 (a), by making the shape of the lid 12 into a dome shape, the side wall can be raised without retaining the rice grains 8 at the connection between the container 11 and the lid 12. All the rice grains 8 can be reliably guided to the substantially bottom center of the container 11.
さらに、 上昇する米粒 8の力が強い場合は、 図 3 ( b) の構成では、 米粒 8が 蓋 1 2に衝突して米粒 8に衝撃を与えることになるが、 図 3 ( a) の構成では米 粒 8が蓋 1 に衝突する衝撃を少なくすることができる。  Furthermore, if the force of the rising rice grain 8 is strong, in the configuration of FIG. 3 (b), the rice grain 8 will collide with the lid 12 and impact the rice grain 8, but the configuration of FIG. 3 (a) Thus, the impact of the rice grains 8 colliding with the lid 1 can be reduced.
また、 図 3 ( a)、 ( b) に示すように、 回転羽根 4の一部または全部が容器 1 1の側壁に並行に形成されている場合、 米粒 8を循環させるためには、 これらの 図に示すように、 回転羽根 4の上端と容器蓋 1 2との間に所定量の隙間 Aが必要 である。 ,  In addition, as shown in FIGS. 3 (a) and 3 (b), when a part or all of the rotating blades 4 are formed in parallel with the side wall of the container 11, in order to circulate the rice grains 8, As shown in the figure, a predetermined gap A is required between the upper end of the rotary blade 4 and the container lid 12. ,
しかしながら、 容器 1 1に投入される米粒 8の量が少量の場合、 図 4 ( b) に 示すように、 容器蓋 1 2が略水平方向に形成されていると、 米粒 8は容器 1 1の 側壁を上昇することができても蓋 1 2の内面に沿って移動することができない場 合が生じる。 一方、 図 4 ( a) に示すように、 蓋 1 2がドーム状に形成されてい る場合には、容器 1 1の上端部と蓋 1 2との接続部を低くすることができるので、 米粒 8の量が少量の場合でも米粒 8は蓋 1 2の内面に沿って移動することができ る。 したがって、 米粒 8の量が少量の場合でも、 米粒 8を容器 1 1の略底部中央 に向かって循環させることができる。 以上より本実施例では、 すべての米粒 8を確実に容器 1 1内で効率的に循環さ せることができるとともに、 米粒 8に与える衝撃を少なくすることができる。 ま た、 米粒 8が少量でも、 確実に米粒 8を循環させることができる。 (実施例 3 ) . However, when the amount of the rice grains 8 put into the container 11 is small, as shown in FIG. 4 (b), if the container lid 12 is formed substantially in the horizontal direction, the rice grains 8 Even if the side wall can be raised, it may not be possible to move along the inner surface of the lid 12. On the other hand, as shown in FIG. 4 (a), when the lid 12 is formed in a dome shape, the connection between the upper end of the container 11 and the lid 12 can be lowered, so that the rice grains Even when the amount of 8 is small, the rice grains 8 can move along the inner surface of the lid 12. Therefore, even when the amount of the rice grains 8 is small, the rice grains 8 can be circulated substantially toward the center of the bottom of the container 11. As described above, in the present embodiment, all the rice grains 8 can be reliably circulated in the container 11 efficiently, and the impact on the rice grains 8 can be reduced. Further, even if the amount of the rice grains 8 is small, the rice grains 8 can be reliably circulated. (Example 3).
本実施例の洗米器は図 5に示すように、 蓋 1 2は略中央部に開口部 Bを備え、 かつ蓋 1 2の略中央部は容器蓋 1 2の端部よりも下方に配置されている。 他の構 成は上記実施例 1と同じである。  As shown in FIG. 5, in the rice washing machine of this embodiment, the lid 12 has an opening B at a substantially central portion, and the substantially central portion of the lid 12 is disposed below the end of the container lid 12. ing. Other configurations are the same as those in the first embodiment.
上記構成において図 5により動作を説明する。 回転羽根 4が動作すると、 米粒 8は容器 1 1の側壁および蓋 1 2の内面に沿つて移動する。 このとき、 蓋 1 2の 中央部は端部よりも下方にあるため、 米粒 8は容器 1 1の略中央部さらに底部に 向かって循環する。そのため、米粒 8を効率的に循環させることができる。 また、 蓋 1 2の中央部が開口部 Bを備えていても米粒 8は蓋 1 2の開口部 Bから外部へ 飛び出すことがない。  The operation of the above configuration will be described with reference to FIG. When the rotating blades 4 operate, the rice grains 8 move along the side wall of the container 11 and the inner surface of the lid 12. At this time, since the central portion of the lid 12 is lower than the end portion, the rice grains 8 circulate substantially toward the central portion of the container 11 and further toward the bottom. Therefore, the rice grains 8 can be efficiently circulated. Also, even if the center of the lid 12 has the opening B, the rice grains 8 do not jump out of the opening B of the lid 12 to the outside.
したがって、容器 1 1内で効率的に米粒 8を循環させることができるとともに、 米粒 8を容器 1 1内に投入して盖 1 2を取り付けた後でも、 蓋 1 2を取り外さず に開口部 Bから新たに米粒 8を投入することができる。  Therefore, the rice grains 8 can be efficiently circulated in the container 11 and, even after the rice grains 8 are put into the container 11 and the lid 12 is attached, the opening B can be removed without removing the lid 12. New rice grains 8 can be put in.
なお、 容器 1 1の上部が図 5に示す蓋 1 2のように、 略中央部に開口部を備え た形状に形成されてもよい。.  The upper portion of the container 11 may be formed in a shape having an opening at a substantially central portion as in a lid 12 shown in FIG. .
(実施例 4) (Example 4)
本実施例では、 図 6に示す案内羽根 1 3は、 容器蓋 1 2の内面に略垂直方向に 形成されている。 他の構成は上記実施例 1と同じである。  In this embodiment, the guide vanes 13 shown in FIG. 6 are formed on the inner surface of the container lid 12 in a substantially vertical direction. Other configurations are the same as those in the first embodiment.
上記構成において動作を説明する。 回転羽根 4が動作すると、 米粒 8が容器 1 1の側壁を上昇してくるが、 このとき、 図 7に示すように、 上昇してきた米粒 8 は案内羽根 1 3によつて進行方向を容器 1 1の側壁から略中央部へ向かうことに なる。 したがって、 上昇してきた米粒 8をより効率的にかつより確実に容器 1 1 の略底部中央へ移動させることができるので、 より効率的に米粒 8を循環させる ことができる。 なお、 案内羽根 1 3は複数個設けられてもよい。 また、 案内羽根 1 3は、 容器 1 1の上部に形成されるものでもよい。 The operation of the above configuration will be described. When the rotating blades 4 are operated, the rice grains 8 rise on the side wall of the container 11. At this time, as shown in FIG. Is moved from the side wall of the container 11 to the substantially central portion by the guide blade 13. Therefore, the rising rice grains 8 can be moved more efficiently and more reliably to the substantially bottom center of the container 11, so that the rice grains 8 can be circulated more efficiently. Note that a plurality of guide vanes 13 may be provided. Further, the guide blade 13 may be formed on the upper part of the container 11.
また、 案内羽根 1 3は、 米粒 8が容器 1 1の側壁から略中央部へ向かうように 流れを変える程度の突起形状のものでもよい。 また、 案内羽根 1 3を蓋 1 2ゃ容 器 1 1とは別部品で構成し、 案内羽根 1 3のみを交換できるようにすれば、 案内 羽根 1 3が米粒との衝突で壊れた場合でも、 容易に案内羽根 1 3のみを交換する ことができる。  Further, the guide blades 13 may be of a projecting shape such that the flow of the rice grains 8 changes from the side wall of the container 11 toward the substantially central portion. In addition, if the guide blade 13 is made of a separate component from the lid 12 and the container 11 so that only the guide blade 13 can be replaced, even if the guide blade 13 is broken due to collision with rice grains, However, only the guide vanes 13 can be easily replaced.
(実施例 5 ) (Example 5)
本実施例では図 8に示すように、案内羽根 1 3は略曲線形状に形成されている。 他の構成は上記実施例 1と同じである。  In the present embodiment, as shown in FIG. 8, the guide blade 13 is formed in a substantially curved shape. Other configurations are the same as those in the first embodiment.
上記構成において動作を説明する。 回転羽根 4が動作すると、 米粒 8が上昇し てくるが、 このとき、 図 9に示すように、 上昇してきた米粒 8は案内羽根 1 3に よって容器 1 1の側壁から略中央部へ滑らかに向かうことになる。  The operation of the above configuration will be described. When the rotating blades 4 operate, the rice grains 8 rise, but at this time, as shown in FIG. 9, the rising rice grains 8 are smoothly moved from the side walls of the container 11 to the substantially central portion by the guide blades 13. I will head.
したがつて、 米粒 8が案内羽根 1 3に衝突する衝撃力を低減することができる とともに案内羽根 1 3の耐久性を向上させることができる。  Therefore, the impact force of the rice grains 8 colliding with the guide blades 13 can be reduced, and the durability of the guide blades 13 can be improved.
(実施例 6 ) (Example 6)
本実施例では、 図 1 0に示すように、 蓋 1 2は、 米粒 8を選択的に通過させな い大きさの第二の開口部 1 4を有している。 他の構成は上記実施例 5と^じであ る。  In the present embodiment, as shown in FIG. 10, the lid 12 has a second opening 14 having a size that does not allow the rice grains 8 to selectively pass therethrough. Other configurations are the same as those of the fifth embodiment.
上記構成において図 1 1により動作を説明する。 回転羽根 4が動作して米粒 8 が上昇すると、 米粒 8は蓋 1 2と衝突することになる。 このとき、 蓋 1 2は第二 の開口部 1 4を有しているので、 米粒 8が蓋 1 2と衝突する衝撃力によって、 米 粒 8同士の擦り合わせにより削り取られたり、 米粒 8と混在していたり付着して いたりする糠 9やごみおよび虫等が第二の開口部 1 4を通過して容器 1 1外へ飛 ばされる。 The operation of the above configuration will be described with reference to FIG. Rotating blades 4 work and rice grains 8 As the rice rises, the rice grains 8 will collide with the lid 12. At this time, since the lid 12 has the second opening 14, the rice grains 8 are scraped off by the rubbing of the rice grains 8 or mixed with the rice grains 8 by the impact force colliding with the lid 12. Bran 9, garbage, insects, and the like that have fallen or adhered are blown out of the container 11 through the second opening 14.
したがって、 米粒 8が蓋 1 2と衝突する衝撃力を利用して、 米粒 8から糠 9、 ごみおよび虫等を分離し、 かつ糠 9、 ごみおよび虫等を容器 1 1の外へ排出する ことができる。 '  Therefore, using the impact force of the rice grains 8 colliding with the lid 12, the rice grains 8 are used to separate the bran 9, garbage and insects from the rice grains 8, and the bran 9, garbage and insects are discharged out of the container 11. Can be. '
なお、 蓋 1 2に形成された第二の開口部 1 4は、 米粒が通過しない大きさであ れば、 いかなる形状でもよいことは言うまでもない。  Needless to say, the second opening 14 formed in the lid 12 may have any shape as long as the rice grain does not pass through.
(実施例 7 ) (Example 7)
本実施例では、 図 1 2に示すように、 容器蓋 1 2はほぼドーム状でかつ米粒を 選択的に通過させない第二の開口部 1 4を有しており、 容器 1 1の周囲には糠回 収部 1 5が備えられている。 他の構成は上記実施例 1と同じである。  In this embodiment, as shown in FIG. 12, the container lid 12 has a second opening 14 that is substantially dome-shaped and does not allow rice grains to selectively pass therethrough, and around the container 11. A bran recovery unit 15 is provided. Other configurations are the same as those in the first embodiment.
上記構成において。 図 1 2により動作を説明する。 米粒 8が上昇して容器蓋 1 2へ移動すると、 糠 9やごみ、 虫等が米粒 8から分離され蓋 1 2から容器 1 1の 外へ排出される。 このとき、 蓋 1 2は略球面形状に形成されているので、 糠 9や ごみ、 虫等は容器 1 1の外周部へ運び出される。そのため、糠 9やごみ、虫等は、 蓋 1 2に再び付着することがない。  In the above configuration. The operation will be described with reference to FIGS. When the rice grains 8 rise and move to the container lid 12, the bran 9, garbage, insects, etc. are separated from the rice grains 8 and discharged from the lid 12 to the outside of the container 11. At this time, since the lid 12 is formed in a substantially spherical shape, the bran 9, garbage, insects, and the like are carried out to the outer peripheral portion of the container 11. Therefore, the bran 9, garbage, insects, etc. do not adhere to the lid 12 again.
そして、 容器 1 1の外周部には糠回収部 1 5が備えられているので、 運び出さ れた糠 9やごみ、 虫等は、糠回収部 1 5に回収される。 したがって、糠 9やごみ、 虫等を糠回収部 1 5から容易に回収することができる。 (実施例 8 ) 本実施例では、 図 1 3に示すように、 案内羽根 1 3は、 米粒 8を選択的に通過 させない大きさの第三の開口部 1 6を有している。 他の構成は上記実施例 1と同 じである。 Since the bran collecting section 15 is provided on the outer periphery of the container 11, the bran 9, garbage, insects, and the like carried out are collected in the bran collecting section 15. Therefore, the bran 9, garbage, insects, etc. can be easily collected from the bran collecting section 15. (Example 8) In the present embodiment, as shown in FIG. 13, the guide blade 13 has a third opening 16 having a size that does not allow the rice grains 8 to selectively pass therethrough. Other configurations are the same as those in the first embodiment.
上記構成において図 1 4により動作を説明する。 回転羽根 4が動作すると米粒 8は容器 1 1の側壁から案内羽根 1 3に沿つて容器 1 1の略中央部へ導かれるが、 このとき、 案内羽根 1 3に米粒 8を第三の開口部 1 6が形成されているため、 米 粒 8が案内羽根 1 3に衝突する時や案内羽根 1 3に沿って移動する時に、 糠 9、 ごみ、虫等が案内羽根 1 3の第三の開口部 1 6を通過して米粒 8から分離される。 したがって、より効率的に米粒 8から糠 9やごみ、虫等を分離することができる。 なお、 本実施例の構成において、 蓋 1 2が米粒 8を選択的に通過させない開口部 1 4を備えた構成にすれば、 実施例 6や 7で述べた効果も得られるので、 より一 層効率的に米粒 8から糠 9やごみ、 虫等を分離することができる。  The operation of the above configuration will be described with reference to FIG. When the rotating blades 4 are operated, the rice grains 8 are guided from the side wall of the container 11 to the substantially central portion of the container 11 along the guide blades 13. When the rice grains 8 collide with the guide blades 13 or move along the guide blades 13 due to the formation of 16, rice bran 9, garbage, insects, etc. will be in the third opening of the guide blades 13. It is separated from the rice grain 8 through the part 16. Therefore, it is possible to more efficiently separate the bran 9, garbage, insects, and the like from the rice grains 8. In the configuration of the present embodiment, if the lid 12 is provided with the opening 14 that does not selectively allow the rice grains 8 to pass through, the effects described in Embodiments 6 and 7 can be obtained. Bran 9, garbage, insects, etc. can be efficiently separated from rice grains 8.
さらに、 蓋 1 2に開口部 1 4および案内羽根 1 3に開口部 1 6を設ける代わり に、 蓋 1 2の内側および案内羽根 1 3に、 ブラシ類や柔軟構造物等の米粒仕上げ 材を配置すれば、 米粒仕上げ材が確実に米粒 8から糠 9やごみ、 虫等を取り除く ことができるので、洗米後の米粒の仕上がり状態をより向上させることができる。  Furthermore, instead of providing the opening 14 in the lid 12 and the opening 16 in the guide blade 13, a rice grain finishing material such as a brush or a flexible structure is placed inside the lid 12 and in the guide blade 13. Then, since the rice grain finishing material can surely remove the bran 9, dust, insects, etc. from the rice grain 8, the finished state of the rice grain after the rice washing can be further improved.
(実施例 9 ) (Example 9)
本実施例では、 図 1 5に示すように、 蓋 1 2は略中央部に開口部 Bを備え、 か つ蓋 1 2の中央部は端部よりも下方に配置されている。 さらに、 蓋 1 2は米粒 8 を選択的に通過させない開口部 1 4を有している。 また、 蓋 1 2の上部には、 容 器 1 1内に空気を送り込む送風手段 1 7が備えられている。 他の構成は上記実施 例 1と同じである。  In this embodiment, as shown in FIG. 15, the lid 12 has an opening B at a substantially central portion, and the central portion of the lid 12 is disposed below the end. Further, the lid 12 has an opening 14 through which rice grains 8 do not selectively pass. Further, a blowing means 17 for blowing air into the container 11 is provided above the lid 12. Other configurations are the same as those in the first embodiment.
上記構成において動作を説明する。回転羽根 4が動作すると、米粒 8は上昇し、 蓋 1 2に沿って容器 1 1の略底部中央へ移動するが、 このとき、 制御手段 6が送 風手段 1 7を,駆動して、 容器 1 1内へ空気が送風される。 The operation of the above configuration will be described. When the rotating blades 4 operate, the rice grains 8 rise and move along the lid 12 to approximately the center of the bottom of the container 11, but at this time, the control means 6 sends the rice. By driving the air means 17, air is blown into the container 11.
容器 1 1内に空気が送風されると、 循環している際に生じる米粒 8同士の擦り 合わせによる米粒 8の温度上昇を制御することができる。  When air is blown into the container 11, it is possible to control the temperature rise of the rice grains 8 due to the rubbing of the rice grains 8 generated during the circulation.
さらに、 送風手段 1 7により容器 1 1内に送り込まれた空気は蓋 1 2の開口部 1 4から容器 1 1外へ排出されるので、 開口部 1 4で、 米粒 8から糠 9やごみ、 虫等をより効率的に分離し容器 1 1外へ排出することができる。 したがって、 米 粒 8の温度上昇を制御することができるとともに、 より効率的に米粒 8から糠 9 やごみ、 虫等を分離して容器 1 1外へ排出することができる。 (実施例 1 0 )  Further, the air sent into the container 11 by the blowing means 17 is discharged out of the container 11 through the opening 14 of the lid 12, so that the rice grain 8 to bran 9, garbage, Insects and the like can be separated more efficiently and discharged out of the container 11. Therefore, the temperature rise of the rice grains 8 can be controlled, and the rice grains 8 can be more efficiently separated from the rice bran 9, garbage, insects, etc., and discharged out of the container 11. (Example 10)
本実施例の洗米器の縦断面図を図 1 6に示す。 本実施例の洗米器は図 1 6に示 すように、 駆動手段 5の駆動軸 2に嵌合され駆動軸 2と共に回転する羽根 4を有 する。 羽根 4は、 図 1 7に示すとおり容器 1 1側面に対しほぼ平行に直立する洗 米部 1と、 洗米部 1と駆動軸 2とを連接する接合部 3とからなる。  FIG. 16 shows a vertical sectional view of the rice washer of this embodiment. As shown in FIG. 16, the rice washer of this embodiment has blades 4 fitted to the drive shaft 2 of the drive means 5 and rotating together with the drive shaft 2. As shown in FIG. 17, the blades 4 are composed of a rice-washing part 1 that stands substantially parallel to the side surface of the container 11 and a joint part 3 that connects the rice-washing part 1 and the drive shaft 2.
以上の構成において動作を説明する。 米粒を容器 1 1内に投入して操作スイツ チ (図示せず) を操作することで、 駆動手段 5が回転を開始し、 駆動軸 2と駆動 軸 2に嵌合される羽根 4を回転させる。  The operation of the above configuration will be described. By putting rice grains into the container 11 and operating an operation switch (not shown), the driving means 5 starts rotating, and the driving shaft 2 and the blade 4 fitted to the driving shaft 2 are rotated. .
羽根 4の回転によって洗米部 1は容器 1 1の側面に対して一定間隔を保ちなが ら接触する米粒に対して回転の接線方向の力を与え、 洗米容器 4の側面へと米粒 を押しつけ、 側面に沿って上昇させる。 押しつける力は洗米部 1が配置される高 さまで連続して生じるので、 洗米部 1の先端より高く上昇した米粒は力を失つて 自由落下をし、 容器 1 1の底面へ戻る。  The rotation of the blades 4 causes the rice washing unit 1 to apply a tangential force of rotation to the rice grains contacting while keeping a constant distance to the side of the container 1 1, thereby pressing the rice grains against the side of the rice washing container 4, Raise along the sides. The pressing force is continuously generated up to the height at which the rice washing unit 1 is arranged. Therefore, the rice grains that have risen higher than the tip of the rice washing unit 1 lose force and fall freely, returning to the bottom of the container 11.
米粒は再び羽根 4に接触するか、 または羽根 4が発生させる空気の流れにより 力を受け、 側面へと移動して同様の動作を繰り返し行う。 この循環を一定時間継 続して、 米粒同士は向きをランダムに変化させながら互いに擦れ合って、 表面の 糠が徐々に除去される。 したがって、 米粒表面の澱粉糸田胞をほとんど傷つけるこ とがなく、処理後の米粒は糠と容易に分離され、手洗いによる洗米操作を軽減し、 炊飯しても米飯の表面が崩れずベたつかない良好な食味を得る米粒を得ることが できる。 The rice grains come into contact with the blade 4 again, or are subjected to the force of the air flow generated by the blade 4, move to the side surface, and repeat the same operation. By continuing this circulation for a certain period of time, the rice grains rub against each other while randomly changing The bran is gradually removed. Therefore, the starch grain on the rice grain surface is scarcely damaged, and the treated rice grain is easily separated from the bran, reducing the rice washing operation by hand washing. Rice grains with good taste can be obtained.

(実施例 3 5 ) (Example 35)
本実施例について、 図 3 4 ( a ) を参照しながら説明する。 本実施例は、 制御 手段が駆動手段を制御して、 羽根の回転数を所定の態様で変ィヒさせるというもの である。  This embodiment will be described with reference to FIG. In this embodiment, the control means controls the driving means to change the rotation speed of the blade in a predetermined manner.
すなわち、 本実施例によれば、 洗米工程において、 制御手段 6は図 3 4 ( b) に示すように、 回転羽根 4を洗米回転数 1^の一定回転数のみで回転させるので はなく、 図 3 4 ( a) に示すように、 洗米工程のうち、 羽根 4の回転数を回転数 よりも高い回転数 N2で回転させる工程を設けることができる。 That is, according to the present embodiment, in the rice washing process, the control means 6 does not rotate the rotating blades 4 only at a constant rotation speed of 1 米 of the rice washing speed, as shown in FIG. 3 as shown in 4 (a), of the rice washing step, it is possible to provide a step of rotating the rotational speed of the blade 4 at a higher than the rotational speed rotational speed N 2.
そのため、 図 4 1に示す、 米粒 1の表面を構成する糊粉層 3を、 従来よりも早 く削り取ることができるので、 従来は洗米するのに t iの時間が必要であった洗 米工程時間を、 図 3 4 ( a) に示すように、 t 2の時間に短縮することができる。 なお、 洗米工程において、 洗米回転数 よりも高い回転数 N 2で常に回転羽根 1 4を回転させると、 米粒 1〖ま糊粉層 3を削り取られるだけでなく澱粉細胞 2が 傷つけられたり、 米粒 1自体が壊れてしまったりすることは言うまでもない。 As a result, the size of the aleurone layer 3 constituting the surface of the rice grains 1 shown in Fig. 41 can be scraped off more quickly than before, and the rice washing process time, which conventionally required ti time for rice washing, the, as shown in FIG. 3 4 (a), it is possible to shorten the time t 2. Incidentally, in the rice washing step, it is rotated constantly rotating blade 1 4 at a high rotational speed N 2 than rice washing rotational speed, or damaged starch cells 2 not only scraped rice grains 1 〖or aleurone layer 3, rice grains Needless to say, 1 itself is broken.
(実施例 3 6 ) · (Example 36)
本実施例では、 図 3 5に示すように、 羽根 4を回転数 よりも高い回転数 N 2 で回転させる工程を、 洗米工程の開始時に行うようにしている。 他の構成は実施 例 3 4と同じである。 本実施例での動作を説明する。 洗米工程開始時は、 図 4 1に示すように、 米粒 3 1は糊粉層 3 3に完全に覆われているので、 図 3 5に示すように、 高い回転数 N 2で回転羽根 4を回転させる工程を、 洗米工程の開始時に行うと、 澱粉細胞 3 2を傷つけることなく糊粉層 3 3のみを削り取ることができる。 In this embodiment, as shown in FIG. 35, the step of rotating the blades 4 at a rotation speed N 2 higher than the rotation speed is performed at the start of the rice washing process. Other configurations are the same as those of the embodiment 34. The operation in the present embodiment will be described. Rice washing step at the start, as shown in FIG. 4 1, since rice grains 3 1 is covered entirely on Norikoso 3 3, as shown in FIG. 35, the rotary blade 4 at a high rotational speed N 2 If the rotating step is performed at the start of the rice washing step, only the aleurone layer 33 can be scraped off without damaging the starch cells 32.
すなわち、 回転羽根 4の回転数を図 3 5に示すように変化させることにより、 洗米工程時間を、実施例 3 4の洗米工程時間 ょりもより短い時間 t 3で洗米す ることができる。 That is, the rotational speed of the rotary blade 4 by changing, as shown in FIG. 35, a rice washing step time may bran rice to Rukoto in Example 3 4 rice washing process time Yori even shorter time t 3.
一方、 図 3 6に示すように、 洗米工程開始時は、 容器 1 1、 羽根 4および駆動 手段 5の温度や米粒 3 1自体の温度は略室温 1\であるため、 .羽根 4を高回転数 N 2で回転させる工程を洗米工程開始時から行うことにより、 米粒 3 1の温度変 化は、 実施例 3 4の場合の温度変化 (図 3 6の特性 A) とは異なり、 図 3 6の特 性 Bのような変化をする。 On the other hand, as shown in Fig. 36, at the start of the rice washing process, the temperature of the container 11, the blades 4 and the driving means 5 and the temperature of the rice grains 31 themselves are approximately room temperature 1 \. by performing the step of rotating the number N 2 from the time of rice washing step starts, rice grains 3 1 temperature change is different from the temperature change in the case of example 3 4 (characteristic a in FIG. 3 6), 3 6 Characteristic B changes like this.
すなわち、 洗米工程終了時の米粒 3 1の温度を実施例 3 4の終了温度 T 2より も低い温度である Τ 3にすることができる。 このため、 米粒 3 1を低温度で洗米 することができ、 米粒 3 1の温度上昇により生じるひびや割れを低減することが できる。 That is, it is possible to T 3 at a temperature lower than the end temperature T 2 of the rice washing step at the end of the rice grains 3 1 temperature Example 3 4. Therefore, the rice grains 31 can be washed at a low temperature, and cracks and cracks caused by the temperature rise of the rice grains 31 can be reduced.
(実施例 3 7 ) (Example 37)
本実施例では、 図 3 7 ( a) および図 3 7 ( b) に示すように、 制御手段 6は、 回転数 1^や回転数 N 2になるまで羽根 4の回転数が徐々に変化するように駆動 手段 5を制御している。 他の構成は上記実施例 3 4と同じである。 In this embodiment, as shown in FIG. 3 7 (a) and FIG. 3 7 (b), the control unit 6, the rotational speed of the blade 4 until rotation speed 1 ^ and the rotational speed N 2 is gradually changed The driving means 5 is controlled as described above. Other configurations are the same as those of the above-described embodiment 34.
本実施例の効果を説明する。 洗米器 5 0は、 使用者が所定量の米粒 3 1を容器 1 1内に投入した後に洗米工程を開始する力、 米粒 3 1が投入された時に、 図 3 8に示すように、 回転羽根 4と容器 1 1との隙間に米粒 3 1が挟み込まれる場合 がある。 この状態で洗米工程を開始して、駆動手段 5が羽根 4を所定回転数 や N2ま で急激に回転させようとすると、 羽根 4と容器 1 1との隙間に挟み込まれた米粒 3 1が、 羽根 4の回転を妨害することになる。 このため、 羽根 4が回転せずに米 粒 1を洗米することができなかったり、 駆動手段 5に高負荷が発生し駆動手段 5 が発煙したり壊れたりする可能性がある。 また、 羽根 4と容器 1 1に挟み込まれ た米粒 3 1が砕けてしまうということも発生する。 The effect of this embodiment will be described. The rice washer 50 has a force to start the rice washing process after the user puts a predetermined amount of rice grains 31 into the container 11, and when the rice grains 31 are thrown, as shown in Fig. 38, the rotating blades Rice grains 31 may be trapped in the gap between 4 and the container 11. Start the rice washing step in this state, the drive means 5 to rotate the blade 4 and N 2 until in rapidly predetermined rotational speed, the rice grains 3 1 sandwiched in the gap between the blade 4 and the container 1 1 However, the rotation of the blade 4 will be obstructed. For this reason, there is a possibility that the rice grains 1 cannot be washed without the blades 4 rotating, or a high load is applied to the driving means 5, and the driving means 5 may smoke or break. In addition, the rice grains 31 sandwiched between the blade 4 and the container 11 may be broken.
そこで、 図 3 7 ( a) に示すように、 羽根 1 4の回転数を所定回転数 や N 2 まで徐々に上昇させることにより、 米粒 3 1が羽根 4と容器 1 1の間に挟み込ま れた状態を減少させ, 米粒 3 1が羽根 4の回転を妨害することを減少させること ができる。 この結果、 羽根 4を所定の回転数 や N 2で回転させることができる とともに、 駆動手段 5に対して急激に大きな負荷のかかるようなことが発生する のを防ぐことができ、 駆動手段 5の発煙や破壌を防ぐことができる。 さらに、 米 粒 3 1にひびが入つたり壊れたりするのを低減することができる。 Therefore, as shown in FIG. 3 7 (a), by gradually increasing the rotational speed of the blade 1 4 to a predetermined speed and N 2, rice grains 3 1 is sandwiched between the blade 4 and the container 1 1 It is possible to reduce the condition and reduce the possibility that the rice grains 31 obstruct the rotation of the blade 4. As a result, the blades 4 can be rotated at a predetermined number of revolutions or N 2 , and it is possible to prevent a sudden large load from being applied to the driving means 5. Smoke and blasting can be prevented. Furthermore, cracking and breaking of the rice grain 31 can be reduced.
なお、 羽根 1 4の回転数を上昇させる場合だけでなく下降させる場合でも徐々 に変化させるようにすればなおよい。 また、 図 3 7 ( b) に示すように、 羽根 4 の回転数を段階的に上昇させたり下降させたりしてもよい。  It is more preferable that the rotation speed is gradually changed not only when the rotation speed of the blade 14 is increased but also when it is lowered. Further, as shown in FIG. 37 (b), the rotational speed of the blade 4 may be increased or decreased stepwise.
また、 洗米工程中に、 羽根 4を一時停止し、 再び所定回転数 N や N2で回転さ せる場合でも、 図 3 7 ( a)、 ( b) に示すように、 回転数を徐々に上昇させたり 下降させたりすればよりよい。 Further, during the rice washing step, even if the stop blade 4 temporarily rotates again at a predetermined rotational speed N and N 2, as shown in FIG. 3 7 (a), (b ), gradually increasing the rotational speed It is better if you let it go down or down.
(実施例 3 8 ) (Example 38)
本実施例では、 制御手段 6は、 洗米工程開始時に羽根 4が正転方向に回転した り逆転方向に回転したりするように、 駆動手段 5を制御するように構成とした。 他の構成は実施例 3 4と同じである。  In the present embodiment, the control means 6 is configured to control the driving means 5 so that the blade 4 rotates in the normal rotation direction or the reverse rotation direction at the start of the rice washing process. Other configurations are the same as those of the embodiment 34.
本実施例の効果を説明する。 実施例 3 6と同様に、 容器 1 1に米粒 3 1が投入 された時は、 図 3 8に示すように、 回転羽根 1 4と容器 5との隙間に米粒 3 1が 挟み込まれてしまうおそれがある。 The effect of this embodiment will be described. As in Example 36, rice grains 31 are put into vessel 11 In such a case, as shown in FIG. 38, there is a possibility that the rice grains 31 may be caught in the gap between the rotating blades 14 and the container 5.
このとき、 羽根 1 4を正転方向や逆転方向に回転させることにより (例えば正 転方向に 1 / 2回転回転した後に逆転方向に 1 / 2回転回転させる動作を複数回 繰り返す等)、図 3 8に示すような、米粒 3 1が羽根 1 4.と容器 1 1との隙間に挟 みこまれた状態を、 実施例 3 6の場合よりもより低減することができる。  At this time, by rotating the blade 14 in the forward direction or the reverse direction (for example, repeating the operation of rotating the half direction in the forward direction and then rotating the same in the reverse direction several times), as shown in FIG. As shown in FIG. 8, the state in which the rice grains 31 are sandwiched in the gap between the blades 14 and the container 11 can be reduced more than in the case of the embodiment 36.
したがって、 羽根 1 4の回転をより滑らかにすることができ、 羽根 4を所定回 転数 N や N2まで急激に回転させることができる。 また、 洗米工程開始時に駆動 手段 5に加わる負荷をより低減することができ、 米粒 3 1にひびが入つたり壊れ たりすることをより低減することができる。 Therefore, the rotation of the blade 14 can be made smoother, and the blade 4 can be rapidly rotated to the predetermined rotation speed N or N 2 . Further, the load applied to the driving means 5 at the start of the rice washing step can be further reduced, and the cracking or breaking of the rice grains 31 can be further reduced.
なお、 実施例 3 6と同様に、 洗米工程中に羽根 4を一時停止し、 再び回転させ る場合においても、 羽根 4を正転方向、 '逆転方向にに回転させた後に所定回転数 まで回転させるようにすればよりよい。 (実施例 3 9 )  In the same manner as in Example 36, when the blades 4 are temporarily stopped during the rice washing process and then rotated again, the blades 4 are rotated in the normal rotation direction and the reverse rotation direction, and then rotated to the predetermined rotation speed. It is better if you let it. (Example 3 9)
図 3 9に示す仕上げ工程は、 図 4 0に拡大図で示すように、 削り取られた糊粉 層 3 3が糠 9となって米粒 3 1の表面に付着しているのを除去する工程である。 この仕上げ工程では、 図 3 9に示すように、 羽根 4は洗米回転数 N よりも低い 仕上げ回転数 N 3で回転するように、 制御手段 6が駆動手段 5を制御する。 他の 構成は上記実施例 3 4と同じである。 The finishing step shown in Fig. 39 is a step of removing the shaved paste layer 33 from becoming the bran 9 and adhering to the surface of the rice grain 31 as shown in the enlarged view in Fig. 40. is there. In this finishing step, as shown in FIG. 3 9, the blade 4 to rotate at a low finish rotational speed N 3 than rice washing rotational speed N, the control unit 6 controls the driving means 5. Other configurations are the same as those of the above-described embodiment 34.
本実施例の効果を説明する。 羽根 4が回転数 N i以上で回転することにより、 米粒 3 1を覆う糊粉層 3 3は米粒 3 1から削り取られるが、 糊粉層 3 3は糠 9と なり、その一部が、 図 4 0に示すように、米粒 3 1の表面に付着した状態になる。 そのため、 削り取られた糠 9を米粒 3 1から完全に分離できない場合が生じる。 そこで、 回転数 よりも低い仕上げ回転数 N3で羽根 4を回転させる仕上げ工 程を洗米工程中、 または洗米工程後に行う。 この仕上げ工程により、 羽根 4は、 低回転数である N 3で回転するので、 米粒 3 1の表面は削り取られることなく、 米粒 1の表面に付着した糠 9のみが除去される。 産業上の利用可能性 The effect of this embodiment will be described. By rotating the blades 4 at the rotation speed N i or more, the aleurone layer 3 3 covering the rice grain 3 1 is scraped off from the rice grain 31, but the aleurone layer 3 3 becomes the bran 9, and a part thereof is shown in FIG. As shown in FIG. 40, the rice grains 31 adhere to the surface. For this reason, there are cases where the shaved bran 9 cannot be completely separated from the rice grain 31. Therefore, fitter to rotate the blade 4 at a low finish rotational speed N 3 than the rotational speed During the rice washing process or after the rice washing process. By this finishing step, the blades 4 rotate at the low rotation speed N 3 , so that the surface of the rice grains 31 is not scraped off, and only the bran 9 adhered to the surfaces of the rice grains 1 is removed.
