Description

本考案は、蒸気を原料層の下方から上方へ通過させて穀物を蒸煮させるための穀物用甑に関する。   The present invention relates to a cereal bowl for steaming steam by passing steam from below to above.

醸造用原料となる穀物を蒸煮する装置として甑が知られている。甑の一例として、特許文献1に記載されているような円筒型甑が挙げられる。特許文献1に記載されている円筒型甑は、白米をバッチ処理で蒸煮するものであり、円筒型甑の下部に円筒蒸気室を設け、上部には浸漬水切後の白米を堆積させる円筒型容器を形成し、上部と下部の間に蒸気を通過させる多孔板等で仕切りを設けたものである。この構成においては、円筒蒸気室に蒸気を噴出し、円筒型容器内の白米堆積層を蒸気が噴き抜けた後、蒸し上がった白米を円筒型甑から排出する。   Koji is known as a device for steaming grains used as raw materials for brewing. An example of the scissors is a cylindrical scissor as described in Patent Document 1. The cylindrical rice bran described in Patent Document 1 is for steaming white rice in a batch process. A cylindrical steam chamber is provided in the lower part of the cylindrical rice cake, and the upper part is a cylindrical container in which white rice after drained drainage is deposited. And a partition is provided between the upper part and the lower part with a perforated plate or the like through which steam passes. In this configuration, steam is jetted into the cylindrical steam chamber, and after steam blows through the white rice deposition layer in the cylindrical container, the steamed white rice is discharged from the cylindrical rice cake.

一方、蒸気が白米に対し均一に供給されなければ、蒸煮した白米に品質のむらが生じ易くなる。このため、特許文献1の円筒型甑においては、蒸気噴出のための構造体として、中央ヘッダから4本の分岐配管を設け、分岐配管には左右に接続する分岐蒸気ノズルを接続したものを用い、分岐蒸気ノズルに設けた蒸気噴出孔から飽和蒸気を円筒蒸気室底面方向に噴き出すようにしている。このことにより、ノズル全体から飽和蒸気を均等に噴出させるようにし、上昇する飽和蒸気が円筒蒸気室上面に対して均等な密度で接触し、円筒状に堆積している白米の中央部と周辺部においてもほぼ等量の蒸気が供給され、均等な蒸煮が可能となるようにしている。   On the other hand, if steam is not supplied uniformly to white rice, unevenness in quality tends to occur in the cooked white rice. For this reason, in the cylindrical scissors of Patent Document 1, four branch pipes are provided from the central header as a structure for jetting steam, and branch pipes connected to the left and right branch steam nozzles are used. The saturated steam is ejected from the steam ejection hole provided in the branch steam nozzle toward the bottom surface of the cylindrical steam chamber. As a result, saturated steam is uniformly ejected from the entire nozzle, and the rising saturated steam comes into contact with the upper surface of the cylindrical steam chamber at an equal density, and the central portion and the peripheral portion of the white rice accumulated in a cylindrical shape In this case, almost the same amount of steam is supplied so that uniform steaming is possible.

特開2004−254624号公報JP 2004-254624 A

しかしながら、特許文献1に記載の円筒型甑においては、蒸気噴出のための構造体を工夫しているが、均等な蒸気噴出を可能とするためには、円筒蒸気室に万遍なく分岐蒸気ノズルを配置した上で、蒸気噴出孔の分布を最適なものにする必要があり(特許文献1の図4参照)、構造体は複雑にならざるを得なかった。また、この構成において、分岐蒸気ノズルから均等に蒸気が噴出し、飽和蒸気が多孔板に対して均等な密度で接触したとしても、多孔板を通過する飽和蒸気の上昇速度や円筒状に堆積している白米を通過する飽和蒸気の速度分布までが一様になるとは限らず、均等な蒸煮が実現されるとは限らなかった。   However, in the cylindrical scissors described in Patent Document 1, a structure for ejecting steam is devised, but in order to enable uniform steam ejection, the branch steam nozzle is uniformly distributed in the cylindrical steam chamber. It is necessary to optimize the distribution of the steam ejection holes (see FIG. 4 of Patent Document 1), and the structure has to be complicated. Further, in this configuration, even if the steam is ejected from the branch steam nozzles evenly and the saturated steam contacts the perforated plate at an equal density, the rising speed of the saturated steam passing through the perforated plate or the cylindrical deposit is accumulated. Even the velocity distribution of saturated steam passing through the white rice is not always uniform, and uniform steaming is not always realized.

本考案は、前記のような従来の問題を解決するものであり、構造を複雑化させることなく、より確実に均一な蒸煮を実現できる穀物用甑を提供することを目的とする。   The present invention solves the above-described conventional problems, and an object thereof is to provide a grain koji that can realize uniform steaming more reliably without complicating the structure.

前記目的を達成するために、本考案の穀物用甑は、穀物を蒸煮させるための穀物用甑であって、側面及び底面を有する甑本体と、前記甑本体の内部に設けた蒸気整流板と、前記蒸気整流板の上方に配置され、穀物を堆積させるためのサナ板と、前記蒸気整流板の下方に設けた蒸気室と、前記蒸気整流板の下方に配置され、前記甑本体の底面側に蒸気供給口を向けた蒸気供給ユニットとを備えたことを特徴とする。この構成によれば、部分的に集中した蒸気の流れが蒸気整流板を通過する際に妨げられて蒸気が分散する。このことにより、蒸気整流板を通過する蒸気の上昇速度の速度分布が均一に整流され、蒸気が均一に噴き上がり、穀物の均一な蒸煮が可能になる。また、蒸気供給口は甑本体の底面側に向いているので、蒸気供給口からの蒸気は、蒸気供給口から直接上昇するのではなく一旦底面に当たるので、蒸気は底面において分散し、蒸気室における蒸気の分布の均一性が高まる。また、蒸気整流板は、多孔板又はこれと同等の機能を発揮する部材で形成すればよい。さらに、蒸気整流板は、端部を甑本体の側面に固定すればよく、特別に複雑な構造にすることなく、甑本体に追加することができる。   In order to achieve the above object, a cereal bowl according to the present invention is a cereal bowl for steaming cereals, a cocoon body having a side surface and a bottom surface, and a steam rectifying plate provided inside the cocoon body. A sana plate for depositing grains, a steam chamber provided below the steam rectifying plate, and a bottom side of the cocoon body disposed below the steam rectifying plate. And a steam supply unit having a steam supply port directed to. According to this configuration, when the partially concentrated steam flow passes through the steam rectifying plate, the steam is dispersed. As a result, the speed distribution of the rising speed of the steam passing through the steam rectifying plate is uniformly rectified, the steam is sprayed uniformly, and the grain can be uniformly cooked. In addition, since the steam supply port faces the bottom surface side of the bowl body, the steam from the steam supply port does not rise directly from the steam supply port but directly hits the bottom surface. Increased uniformity of vapor distribution. Moreover, what is necessary is just to form a steam baffle plate with the member which exhibits a porous board or a function equivalent to this. Furthermore, the steam rectifying plate only needs to be fixed to the side surface of the cocoon body, and can be added to the cocoon body without a specially complicated structure.

前記本考案の穀物用甑においては、以下の各構成とすることが好ましい。前記蒸気整流板が多孔板で形成され、前記多孔板の開口率が5%以上15%未満であることが好ましい。この構成によれば、蒸気整流板の整流効果を確保しつつ、蒸煮時間が長くなり過ぎないようにすることができる。すなわち、開口率が高過ぎると蒸気の流れを妨げる役割を果たす効果が低くなって整流効果が弱まり、開口率が低過ぎると蒸気整流板を通過する蒸気量が少なくなり、蒸煮時間が長くなり過ぎる。   The grain basket according to the present invention preferably has the following configurations. The vapor rectifying plate is preferably formed of a perforated plate, and the aperture ratio of the perforated plate is preferably 5% or more and less than 15%. According to this configuration, it is possible to prevent the steaming time from becoming too long while ensuring the rectifying effect of the steam rectifying plate. That is, if the aperture ratio is too high, the effect of hindering the flow of steam is reduced and the rectification effect is weakened. .

前記甑本体の側面は円筒形であり、前記蒸気供給ユニットは前記蒸気供給口を複数備え、前記各蒸気供給口を、前記甑本体の底面中心から描いた同心円上に配置し、かつ前記底面中心を通り前記同心円を複数の領域に等分する線上に配置し、前記複数の領域のそれぞれに、蒸気が均等に供給されるようにしたことが好ましい。この構成によれば、蒸気室における蒸気の分布の均一性がより高まる。   The side surface of the bowl body is cylindrical, the steam supply unit includes a plurality of the steam supply ports, each steam supply port is arranged on a concentric circle drawn from the bottom surface center of the bowl body, and the bottom surface center It is preferable that the concentric circles are arranged on a line that equally divides into a plurality of regions so that steam is evenly supplied to each of the plurality of regions. According to this configuration, the uniformity of the distribution of steam in the steam chamber is further increased.

前記蒸気供給口から前記蒸気整流板までの高さが180mm以上400mm未満であることが好ましい。この構成によれば、蒸気整流板に結露水が付着しにくくなって蒸気整流板の整流効果が確保し易くなることに加え、必要な蒸気量や甑本体の大きさが適正になる。すなわち、蒸気供給口から蒸気整流板までの高さが低過ぎると、甑本体の底面に蒸気が当たった際に生成される結露水が飛散して蒸気整流板に付着する。このことにより蒸気整流板の整流効果が妨げられ、蒸気整流板の整流効果が低下する。他方、同高さが高過ぎると、蒸気整流板の整流効果を確保するのに多くの蒸気が必要になることに加え、甑本体が必要以上に大きくなってしまう。   The height from the steam supply port to the steam rectifying plate is preferably 180 mm or more and less than 400 mm. According to this configuration, it is difficult for dew condensation water to adhere to the steam rectifying plate and it becomes easy to ensure the rectifying effect of the steam rectifying plate, and the necessary amount of steam and the size of the basket body are appropriate. That is, if the height from the steam supply port to the steam rectifying plate is too low, the dew condensation water generated when the steam hits the bottom surface of the bowl main body is scattered and adheres to the steam rectifying plate. This hinders the rectifying effect of the steam rectifying plate and reduces the rectifying effect of the steam rectifying plate. On the other hand, if the height is too high, a large amount of steam is required to secure the rectifying effect of the steam rectifying plate, and the cocoon body becomes larger than necessary.

前記蒸気整流板から前記サナ板までの高さが50mm以上200mm未満であることが好ましい。この構成によれば、蒸気整流板で整流した蒸気が再び部分的に集中することが防止され、蒸気の均一な噴き上がりがより確実になる。   The height from the steam rectifying plate to the sana plate is preferably 50 mm or more and less than 200 mm. According to this configuration, the steam rectified by the steam rectifying plate is prevented from partially concentrating again, and the uniform spraying of the steam becomes more reliable.

前記蒸気整流板及び前記サナ板を水平に設置するための支持部材を設けたことが好ましい。この構成によれば、蒸気の均一な噴き上がりに寄与する。   It is preferable that a support member for horizontally installing the steam rectifying plate and the sana plate is provided. According to this structure, it contributes to the uniform spout of a vapor | steam.

蒸気の不純物を取り除く機能を有している整蒸器を設けており、前記整蒸器で発生させた飽和蒸気を前記蒸気供給ユニットへ供給することが好ましい。この構成によれば、整蒸器から排出される蒸気は、不純物の取り除かれた乾き度の高い蒸気となり、サナ板上の穀物へ蒸気を供給した際に、穀物への不純物の混入や余分な水分の付与が防止され、蒸煮後の穀物の品質が高まる。   It is preferable that a steam conditioner having a function of removing steam impurities is provided, and saturated steam generated by the steam conditioner is supplied to the steam supply unit. According to this configuration, the steam discharged from the steam conditioner becomes steam with high dryness from which impurities have been removed. When steam is supplied to the grain on the sana plate, impurities are mixed into the grain and excess moisture is present. Is prevented, and the quality of the grain after cooking is increased.

本考案の効果は前記のとおりであり、要約すれば、蒸気整流板を設けたことにより、蒸気整流板を通過する蒸気の上昇速度の速度分布が均一に整流され、蒸気が均一に噴き上がり、穀物の均一な蒸煮が可能になる。また、蒸気供給口は甑本体の底面側に向いているので、蒸気は底面において分散し、蒸気室における蒸気の分布の均一性が高まる。また、蒸気整流板は、特別に構造が複雑になることなく、甑本体に追加することができる。   The effect of the present invention is as described above. In summary, by providing the steam rectifying plate, the speed distribution of the rising speed of the steam passing through the steam rectifying plate is uniformly rectified, and the steam is jetted uniformly. Allows uniform steaming of grains. Further, since the steam supply port faces the bottom surface side of the main body, the steam is dispersed on the bottom surface, and the uniformity of the distribution of the steam in the steam chamber is enhanced. Further, the steam rectifying plate can be added to the bag main body without any special complexity.

以下、本考案の一実施形態について、図面を参照しながら説明する。図1は、本考案の一実施形態に係る穀物用甑1を示す構成図であり、図2は図1のAA線における断面図である。図1は、甑本体2を縦断面の状態で図示することにより甑本体2の内部構造を示している。本図において、穀物用甑1を構成する甑本体1以外の部品や器具は説明の便宜のため、実線や破線で示している。   Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a configuration diagram showing a grain shed 1 according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view taken along line AA of FIG. FIG. 1 shows the internal structure of the heel body 2 by illustrating the heel body 2 in a longitudinal cross-sectional state. In this figure, parts and instruments other than the cocoon main body 1 constituting the cereal basket 1 are shown by solid lines or broken lines for convenience of explanation.

最初に図1を参照しながら、穀物用甑1の概要を説明する。穀物用甑1は、白米等の穀物を蒸煮する装置である。穀物用甑1は甑本体2を備えており、甑本体2の内部に各種構成部品が配置されている。甑本体2は側面3及び底面4を有しており、本実施形態では側面3は円筒形である。甑本体2の内部には蒸気室7が形成されており、蒸気室7内へは、蒸気供給ユニット8からの蒸気が供給される。   First, the outline of the grain basket 1 will be described with reference to FIG. The grain rice bran 1 is an apparatus for steaming grains such as white rice. The grain basket 1 includes a basket body 2, and various components are arranged inside the basket body 2. The bag main body 2 has a side surface 3 and a bottom surface 4, and in the present embodiment, the side surface 3 is cylindrical. A steam chamber 7 is formed inside the main body 2, and steam from the steam supply unit 8 is supplied into the steam chamber 7.

また、甑本体2の内部には穀物を堆積させるためのサナ板5が配置されている。サナ板5は、甑本体2の側面3に固定された支持部材6上に支持されている。サナ板5は多孔板で形成されている。蒸気供給ユニット7からの蒸気は、サナ板5を通過し、サナ板5上に堆積させた穀物(図示せず)を噴き抜けて、穀物が蒸煮される。   In addition, a sana plate 5 for depositing grains is disposed inside the cocoon body 2. The sana plate 5 is supported on a support member 6 fixed to the side surface 3 of the heel body 2. The sana plate 5 is a perforated plate. The steam from the steam supply unit 7 passes through the sana plate 5 and blows through the cereal (not shown) deposited on the sana plate 5 so that the cereal is cooked.

サナ板5の下方には、蒸気整流板10を設けている。蒸気整流板10は、甑本体2の側面3に固定された支持部材11上に支持されている。蒸気整流板10は、蒸気供給ユニット8からの部分的に集中した蒸気の流れを妨げつつ通過できるように構成されている。蒸気整流板10は、多孔板(例えばパンチングメタル)で形成してもよく、多孔板と同等の機能を発揮するものであれば、他の部材であってもよい。蒸気整流板10は、蒸気供給ユニット8からの蒸気を均一に噴き上げるために設けたものであり、詳細は後に説明する。   A steam rectifying plate 10 is provided below the sana plate 5. The steam rectifying plate 10 is supported on a support member 11 fixed to the side surface 3 of the basket main body 2. The steam rectifying plate 10 is configured to be able to pass while preventing a partially concentrated steam flow from the steam supply unit 8. The vapor rectifying plate 10 may be formed of a perforated plate (for example, punched metal), and may be another member as long as it exhibits a function equivalent to that of the perforated plate. The steam rectifying plate 10 is provided in order to spray the steam from the steam supply unit 8 uniformly, and details will be described later.

前記のとおり、サナ板5は支持部材6上に支持され、蒸気整流板10は支持部材11上に支持されているので、サナ板5及び蒸気整流板10を水平に設置することができる。このことも、蒸気の均一な噴き上がりに寄与する。   As described above, since the sana plate 5 is supported on the support member 6 and the steam rectifying plate 10 is supported on the support member 11, the sana plate 5 and the steam rectifying plate 10 can be installed horizontally. This also contributes to uniform jetting of steam.

整蒸器14には蒸気供給源であるボイラ(図示せず)からの蒸気が供給され(矢印a参照)、蒸気供給ユニット8には、整蒸器14を通過した蒸気が供給される。すなわち、整蒸器14は蒸気の供給経路にあり、整蒸器14で発生させた蒸気を排出する蒸気排出口12を設けている。蒸気排出口12と蒸気供給ユニット8は、蒸気配管13を介して接続されている。このことにより、整蒸器14で発生させた蒸気は、蒸気配管13を経て蒸気供給ユニット8に供給される。   Steam from a boiler (not shown) that is a steam supply source is supplied to the steam conditioner 14 (see arrow a), and steam that has passed through the steam adjuster 14 is supplied to the steam supply unit 8. That is, the steam conditioner 14 is in the steam supply path, and is provided with a steam outlet 12 for discharging steam generated by the steam conditioner 14. The steam outlet 12 and the steam supply unit 8 are connected via a steam pipe 13. Thus, the steam generated by the steam conditioner 14 is supplied to the steam supply unit 8 through the steam pipe 13.

整蒸器14は、水の中に直接蒸気を噴き込んで蒸気の不純物を取り除く機能を有しているので、整蒸器14から排出される蒸気は、不純物の取り除かれた乾き度の高い飽和蒸気となる。このため、サナ板5上の穀物へ蒸気を供給した際に、穀物への不純物の混入や余分な水分の付与が防止され、蒸煮後の穀物の品質を高めることができる。   Since the steam conditioner 14 has a function of removing steam impurities by directly injecting steam into the water, the steam discharged from the steam conditioner 14 is saturated steam with high dryness from which impurities are removed. Become. For this reason, when steam is supplied to the grain on the sana plate 5, the mixing of impurities into the grain and the application of excess moisture are prevented, and the quality of the grain after cooking can be improved.

蒸気供給ユニット8の蒸気供給口9は、甑本体2の底面4側に向いている。このため、蒸気供給口9からの蒸気は、甑本体2の底面4に向けて噴出し、その後、蒸気整流板10に向けて上昇する。すなわち、蒸気は蒸気供給口9から直接上昇するのではなく一旦底面4に当たるので、蒸気は底面4において分散し、蒸気室7内における蒸気の分布の均一性が高まる。   The steam supply port 9 of the steam supply unit 8 faces the bottom surface 4 side of the bowl main body 2. For this reason, the steam from the steam supply port 9 is ejected toward the bottom surface 4 of the bowl main body 2 and then rises toward the steam rectifying plate 10. That is, since the steam does not directly rise from the steam supply port 9 but once hits the bottom surface 4, the steam is dispersed on the bottom surface 4 and the uniformity of the distribution of the steam in the steam chamber 7 is increased.

以上、本実施形態に係る穀物用甑1の概要を説明したが、以下、蒸気整流板10の役割を中心に説明しながら、本実施形態についてより具体的に説明する。前記のとおり、本実施形態においては、蒸気供給口9からの蒸気を一旦底面4に当てる構成により、蒸気室7内における蒸気分布の均一性を高めるようにしている。さらに、甑本体2の内部に蒸気整流板10を設けることにより、蒸気分布の均一性を一層高めるようにしている。   The outline of the grain basket 1 according to the present embodiment has been described above. Hereinafter, the present embodiment will be described in more detail while focusing on the role of the steam rectifying plate 10. As described above, in the present embodiment, the configuration in which the steam from the steam supply port 9 is once applied to the bottom surface 4 improves the uniformity of the steam distribution in the steam chamber 7. Furthermore, by providing the steam rectifying plate 10 inside the main body 2, the uniformity of the steam distribution is further enhanced.

蒸気整流板10は、サナ板5上に堆積させた穀物を均一に蒸煮させるために設けた部材である。蒸気室7は蒸気整流板10の下方にあり、穀物を堆積させるサナ板5は蒸気整流板10の上方にあるので、蒸気室7からの蒸気は、蒸気整流板10を通過してサナ板5に到達する。   The steam rectifying plate 10 is a member provided for uniformly steaming the grains deposited on the sana plate 5. Since the steam chamber 7 is below the steam rectifying plate 10 and the sana plate 5 on which the grain is deposited is above the steam rectifying plate 10, the steam from the steam chamber 7 passes through the steam rectifying plate 10 and passes through the sana plate 5. To reach.

蒸気整流板10は、多孔板又はこれと同等の機能を発揮する部材で形成されているので、蒸気は蒸気整流板10を通過しつつ、蒸気の流れが妨げられて蒸気が分散する。このことにより、蒸気整流板10を通過する蒸気の上昇速度の速度分布が均一に整流され、蒸気が均一に噴き上がり、穀物の均一な蒸煮が可能になる。   Since the steam rectifying plate 10 is formed of a perforated plate or a member that exhibits a function equivalent to this, the steam flows through the steam rectifying plate 10 while the steam flows and is dispersed. Thereby, the speed distribution of the rising speed of the steam passing through the steam rectifying plate 10 is uniformly rectified, the steam is sprayed uniformly, and the grain can be uniformly cooked.

具体的には、蒸気整流板10の下方における蒸気の分布は、蒸気供給口9の真上付近における比率が高くなる。また、図1のように、甑本体2の底面4が中央が低くなるように湾曲している場合は、蒸気の流れが中央部に集まり易い。これらのことから、蒸気の噴き上がりが不均一になると、穀物の一部が集中的に加熱され、蒸煮も不均一になる。本実施形態では、前記のとおり、蒸気整流板10を通過した蒸気が整流されて均一に噴き上がることで、穀物の一部が集中的に加熱されることが防止され、穀物の均一な蒸煮が可能になる。   Specifically, the ratio of the distribution of the steam below the steam rectifying plate 10 near the steam supply port 9 is high. In addition, as shown in FIG. 1, when the bottom surface 4 of the bag main body 2 is curved so that the center is lowered, the flow of steam tends to gather at the center. For these reasons, when the spray of steam becomes uneven, a part of the grain is heated intensively and the steaming becomes uneven. In the present embodiment, as described above, the steam that has passed through the steam rectifying plate 10 is rectified and sprayed uniformly, so that a part of the grain is prevented from being heated intensively, and the uniform cooking of the grain is achieved. It becomes possible.

また、蒸気整流板10は、多孔板又はこれと同等の機能を発揮する部材で形成され、その支持のためには甑本体2の側面3に支持部材11を固定すれば足りるので、特別に構造が複雑になることなく、甑本体2に追加することができる。   Further, the steam rectifying plate 10 is formed of a perforated plate or a member that exhibits a function equivalent to this, and it is only necessary to fix the supporting member 11 to the side surface 3 of the heel body 2 for its support. Can be added to the bag body 2 without complication.

蒸気整流板10をパンチングメタル等の多孔板で形成した場合、多孔板の開口率は5%以上15%未満が好ましい。この範囲中、より好ましい範囲は8%以上12%未満である。この範囲内であれば、蒸気整流板10の整流効果を確保しつつ、蒸煮時間が長くなり過ぎないようにすることができる。すなわち、開口率が高過ぎると蒸気の流れを妨げる役割を果たす効果が低くなって整流効果が弱まり、開口率が低過ぎると蒸気整流板10を通過する蒸気量が少なくなり、蒸煮時間が長くなり過ぎる。   When the steam rectifying plate 10 is formed of a perforated plate such as a punching metal, the aperture ratio of the perforated plate is preferably 5% or more and less than 15%. In this range, a more preferable range is 8% or more and less than 12%. Within this range, it is possible to prevent the steaming time from becoming too long while ensuring the rectifying effect of the steam rectifying plate 10. That is, if the opening ratio is too high, the effect of hindering the flow of steam is reduced and the rectification effect is weakened. If the opening ratio is too low, the amount of steam passing through the steam rectifying plate 10 is reduced and the cooking time is increased. Pass.

前記のとおり、蒸気整流板10自体で蒸気を均一に噴き上げる効果を発揮させることができるが、蒸気整流板10の高さ方向の位置の設定によって、その効果の発揮をより確実にすることが望ましい。具体的には、図1において、蒸気供給口9から蒸気整流板10までの高さH1は180mm以上400mm未満であることが好ましい。この構成によれば、蒸気整流板10に結露水が付着しにくくなって蒸気整流板10の整流効果が確保し易くなることに加え、必要な蒸気量や甑本体2の大きさが適正になる。すなわち、高さH1が低過ぎると、甑本体2の底面4に蒸気が当たった際に生成される結露水が飛散して蒸気整流板10に付着する。このことにより蒸気整流板10の整流効果が妨げられ、蒸気整流板10の整流効果が低下する。他方、高さH1が高過ぎると、蒸気整流板10の整流効果を確保するのに多くの蒸気が必要になることに加え、甑本体2が必要以上に大きくなってしまう。   As described above, the steam rectifying plate 10 itself can exert the effect of spraying steam uniformly. However, it is desirable that the effect of the steam rectifying plate 10 be made more reliable by setting the position of the steam rectifying plate 10 in the height direction. . Specifically, in FIG. 1, the height H1 from the steam supply port 9 to the steam rectifying plate 10 is preferably 180 mm or more and less than 400 mm. According to this configuration, it is difficult for condensed water to adhere to the steam rectifying plate 10 and it is easy to ensure the rectifying effect of the steam rectifying plate 10, and the necessary amount of steam and the size of the bowl main body 2 are appropriate. . That is, if the height H <b> 1 is too low, the dew condensation water that is generated when the steam hits the bottom surface 4 of the bag body 2 scatters and adheres to the steam rectifying plate 10. This hinders the rectifying effect of the steam rectifying plate 10 and reduces the rectifying effect of the steam rectifying plate 10. On the other hand, if the height H1 is too high, a large amount of steam is required to secure the rectifying effect of the steam rectifying plate 10, and the bag body 2 becomes larger than necessary.

また、蒸気整流板10からサナ板までの高さH2は50mm以上200mm未満であることが好ましい。高さH2がこの範囲内であれば、蒸気整流板10で整流した蒸気が再び拡散することが防止され、蒸気の均一な噴き上がりがより確実になる。   Further, the height H2 from the steam rectifying plate 10 to the sana plate is preferably 50 mm or more and less than 200 mm. If the height H2 is within this range, the steam rectified by the steam rectifying plate 10 is prevented from diffusing again, and the uniform spraying of the steam becomes more reliable.

次に、蒸気供給ユニット8についてより具体的に説明する。図2において、蒸気供給ユニット8は蒸気供給口9を4箇所に備えている。蒸気供給口9は、甑本体2の底面4の中心15から描いた同心円16上に配置し、かつ中心15を通り同心円16を4つの領域21〜24に等分する線17上に配置している。この配置により、4つの領域21〜24に蒸気が均等に供給されるようにしている。このことにより、蒸気室7における蒸気の分布の均一性をより高めるようにしている。   Next, the steam supply unit 8 will be described more specifically. In FIG. 2, the steam supply unit 8 includes four steam supply ports 9. The steam supply port 9 is disposed on a concentric circle 16 drawn from the center 15 of the bottom surface 4 of the bowl main body 2, and is disposed on a line 17 that passes through the center 15 and equally divides the concentric circle 16 into four regions 21 to 24. Yes. With this arrangement, steam is uniformly supplied to the four regions 21 to 24. Thereby, the uniformity of the distribution of the steam in the steam chamber 7 is further improved.

図1及び図2に示した、蒸気供給ユニット8の構成や蒸気供給口9の配置は一例であり、この構成に限るものではない。例えば、図2では、同心円16が4つの領域21〜24に分割される例を示しているが、これに限るものではなく、複数の領域に均等に分割されていればよい。   The configuration of the steam supply unit 8 and the arrangement of the steam supply ports 9 shown in FIGS. 1 and 2 are examples, and the present invention is not limited to this configuration. For example, although FIG. 2 shows an example in which the concentric circle 16 is divided into four regions 21 to 24, the present invention is not limited to this, and it is only necessary to be equally divided into a plurality of regions.

以下、本実施形態の実施例について説明する。本実施例の構成は、図1及び図2と同様である。具体的には、蒸気供給ユニット8は、蒸気供給口9を4箇所に設けた構成とした。蒸煮対象の穀物は米とし、1バッチ当たりの原料元重量は600〜800kgの範囲内とした。蒸気供給口9から蒸気整流板10までの高さH1は260mmとし、蒸気整流板10からサナ板5までの高さH2は150mmとした。蒸気整流板10を多孔板で形成し、開口率を10%とした。   Hereinafter, examples of the present embodiment will be described. The configuration of this embodiment is the same as that shown in FIGS. Specifically, the steam supply unit 8 has a configuration in which the steam supply ports 9 are provided at four locations. The grain to be cooked was rice, and the raw material weight per batch was in the range of 600 to 800 kg. The height H1 from the steam supply port 9 to the steam rectifying plate 10 was 260 mm, and the height H2 from the steam rectifying plate 10 to the sana plate 5 was 150 mm. The vapor rectifying plate 10 was formed of a perforated plate, and the aperture ratio was 10%.

前記構成の実施例を運転し米を蒸煮したところ、蒸気整流板10を通過する蒸気の上昇速度は蒸気整流板10の全体に亘り約0.1m/sとなり、蒸気の噴き上がりが均一になり、蒸気整流板10による整流効果が確認できた。また、蒸煮後の米を複数個所採取したところ、含水率は37〜38%であり均一な蒸煮が確認できた。   When the embodiment of the above configuration is operated and rice is cooked, the rising speed of the steam passing through the steam rectifying plate 10 is about 0.1 m / s over the entire steam rectifying plate 10, and the steam squirting becomes uniform. The rectifying effect by the steam rectifying plate 10 was confirmed. Further, when a plurality of cooked rices were collected, the water content was 37 to 38%, and uniform cooking was confirmed.
