Description

【０００１】
【産業上の利用分野】
本発明は、加熱するだけで簡単に食に供することができる包装穀物等を製造するための穀物等の調理装置に関する。
【０００２】

加熱するだけで簡単に食に供することができる包装穀物（例えば米飯類）等を蒸し調理する装置としては、例えば、蒸し室を有し、この蒸し室内において、特願平６年８０７６５号公報に記載の穀物調理用耐熱容器のような通気性を有する容器内に蒸し調理すべき穀物を入れた状態で一定時間高温の水蒸気中に置くことにより、蒸し調理するものが提案されている。
前記蒸し調理装置においては、炊き上がりを良好にするために一定の内圧下で蒸し調理を行なう場合があるが、この様な場合には、蒸し室の容器入口および搬出口に例えば２重扉を設けて蒸し室の内部圧力を維持することが一般的である。
【０００３】
【発明が解決しようとする課題】
ところで、前記のような穀物等の蒸し調理装置の場合、前記２重扉は、内外の扉を交互に開閉することにより、蒸し室内の内圧低下を略防止できるものの、容器の通過の度に前記内外の扉間に高圧空気が放出されるため随時水蒸気を大量に補充する必要があり、圧力の維持に不満があった。また、前記２重扉は、各扉について複雑な開閉機構が必要である上、蒸し室内の圧力を保持するためには内外の扉の開閉のタイミングを制御する機構も必要であり、コストが上昇するといった問題もある。
【０００４】

【００１７】
【実施例】
以下本発明の穀物等の調理装置の第１実施例を、図１から図５を参照して説明する。
本発明の穀物等の調理装置は、ボックス状の蒸し室１と、この蒸し室１に対して米等の穀物を入れた容器２を搬入・搬出する容器搬入路３および容器搬出路４とで概略構成されている。これら容器搬入路３および容器搬出路４は、蒸し室１の対向する組を形成する側壁のそれぞれに設けられ、かつ同一直線上に配置されている。
【００１８】
図１に示すように、前記蒸し室１内には、前記容器搬入路３から搬入された容器２を蒸し室１内に開口する容器搬出路４の入り口５まで搬送する搬送コンベア６が配置されている。また、蒸し室１内には、高温の蒸気を供給する図示しない蒸気供給機構が設けられている。前記搬送コンベア６の両側部には、図２に示すように、容器２の搬送コンベア６からの落下を防止するガイド部材６ａが対向配置されている。また、搬送コンベア６の表面は、搬送コンベア６上の容器２との間に、十分な摩擦力を生じる構成とされている。
前記容器２は、有底円筒状のカップであって、通気性を有している。
【００１９】
前記容器搬入路３は、角筒状に形成され、容器２が搬入される搬入路入口７が蒸し室１外に開口され、搬入路入口７から送り込まれた容器２を前記搬送コンベア６に引き渡す搬入路出口８が蒸し室１内に開口されている。容器搬入路３の内壁面は、開口部を上側に向けて送り込まれた容器２の外面および上下両端面に密接する形状に形成され、容器２の外面との間に蒸し室１内部の蒸気が漏れない程度の気密性を維持するようになっている。前記搬入路入口７には、前記蒸し室１の内圧や容器搬入路３内壁面との摺動抵抗に抗して容器搬入路３内に容器２を押し込むための圧入機構９が設けられている。また容器搬入路３は、容器２の直径よりやや長い長さに形成されている。
前記容器搬出路４は、前記容器２と同様の内壁面形状を有する角筒状であって、搬出路入口５が蒸し室１内に開口されるとともに、搬出路出口１０が蒸し室１外に開口されている。搬出路出口１０には、搬出路出口１０の気密を維持しつつ容器２を容器搬出路４から受け取る受取機構１１が設けられている。また容器搬出路４は、容器２の直径よりやや長い長さに形成されている。
【００２０】
前記圧入機構９は、図３に示すように、ツインローター方式であって、搬入路入口７の外側において容器２の搬送軸線の両側部に対向配置された一対のローター１２を主体として構成されている。
前記受取機構１１は、前記圧入機構９と同様に構成されたツインローター方式とされている。
【００２１】
前記穀物等の調理装置によれば、米等の穀物が入った容器２を圧入機構９によって搬入路入口７に送り込み、容器搬入路３を通って蒸し室１内に搬入された容器２を一定時間保持して内部の穀物を蒸し調理した後、穀物の蒸し調理の完了した容器２を容器搬出路４を介して搬出路出口１０から搬出する。前記圧入機構９は、容器２を蒸し室１の内圧に抗して搬入路入口７内に押し込む。搬入路入口７に押し込まれた容器２は、順次、後続の容器２によって搬送方向前方に押し出され、容器搬入路３内を蒸し室１に向かって移動する。この際、１以上の容器２の外面が常時容器搬入路３内面に密接状態になっているので、蒸し室１内の高圧水蒸気が容器搬入路３を介して漏出することは無い。蒸し室１内に至った容器２は、ガイド部材６ａ、６ａの間にガイドされつつ容器搬出路４方向に搬送される。この際、前記搬送コンベア６が、前記圧入機構９と同期して作動し、容器２を容器搬出路４方向に搬送する。
搬出路入口５に送り込まれた容器２は、外面が容器搬出路４内面と摺接しつつ前記圧入機構９および搬送コンベア６の搬送力によって容器搬出路４内を搬出路出口１０に送り出され、搬出路出口１０において受取機構１１によって定期的に排出される。受取機構１１は、前記圧入機構９および搬送コンベア６と同期して作動する。この際、１以上の容器２外面と容器搬出路４内面との密接が常時維持されているので、容器搬出路４を介して蒸し室１内の高圧水蒸気が漏出することは無い。
【００２２】
したがって、前記穀物等の調理装置によれば、容器２が容器搬入路３および容器搬出路４内面との密接状態を保持しつつ摺動して蒸し室１の内外に移動するので、容器２の通過による蒸し室１内の高圧水蒸気の漏出が防止され、蒸し室１の内圧が保持される。また、圧入機構９および受取機構１１は、構成が単純で製造が容易であり、しかも安価である。
容器２の移動によって容器２同士の隙間分の体積の外気が蒸し室１内に運ばれ、同じ体積の蒸し室１内の水蒸気が蒸し室１外に運ばれるが、従来の２重扉に比して水蒸気の排出量が極めて少なく、蒸し室１内圧の保持は極めて容易である。
【００２３】
なお、蒸し室１内における搬送コンベア６の設置は必須では無く、容器２を水平移動可能に支持する構成であれば、平板や棒材等であっても構わない。
また、容器搬入路３、容器搬出路４内面には、容器２との摺動抵抗を低下させる加工を施すことも可能である。
本実施例の穀物等の調理装置は、米以外、麦、大豆、小豆等の穀物や、惣菜の蒸し調理に利用することもできる。
容器搬入路３および容器搬出路４は、蒸し室１内の蒸気が漏出しない構造であれば、内壁面を容器２の外周面と密接する形状に形成する必然性は無く、潤滑油やその他の接触構造体を介して容器２と接触するようにしてもよい。また、軸方向の長さが長くなれば、流路抵抗によっても蒸気の漏出が防止されるので、容器搬入路３および容器搬出路４内壁面の容器との密接度を低くすることも可能である。
【００２４】
以下、本発明の穀物等の調理装置の第２実施例を図４を参照して説明する。
本実施例の穀物等の調理装置は、前記第１実施例の穀物等の調理装置において、前記搬出路出口１０にツインローター方式の受取機構１１にかえてシングルローター方式の受取機構１３が設けられたものである。
前記受取機構１３は、全体が気密な材質で形成された本体１４と、この本体１４内のローター設置空間１５に回転自在に設けられた概略円盤状のローター１６とで構成されている。
前記本体１４には、搬出路出口１０から容器２を受け取る受取口１７および受取口１７において受け取った容器２を定期的に排出する排出口１８が、それぞれ前記ローター設置空間１５に連通して開口されている。これら受取口１７および排出口１８は、同一直線上に配置されている。前記排出口１８には、容器２を排出口１８外方に送り出す図示しない送り出し機構が設けられている。
前記ローター設置空間１５の内面は、ローター１６の外面と摺動可能な形状に形成されている。ローター設置空間１５とローター１６との間は気密にシールされている。
前記ローター１６には、前記受取口１７からローター設置空間１５内に取り込まれた容器２を収納して、自身の回転によってローター１６周方向に搬送する容器搬送部１９が外周面に複数開口されている。これら容器搬送部１９は、ローター１６周方向において均等配置されている。
【００２５】
本実施例の穀物等の調理装置によれば、前記圧入機構９および搬送コンベア６が搬出路出口１０に容器２を送り出し、搬出路出口１０に至った容器２を受取口１７においてローター１６の容器搬送部１９に収納した後ローター１６の回転によって排出口１８に搬送し、排出口１８外方に排出する。前記ローター１６は、圧入機構９および搬送コンベア６と同期して作動し、圧入機構９および搬送コンベア６によって容器２が搬送方向に送り出された際に容器搬送部１９を受取口１７に位置させる。そして圧入機構９および搬送コンベア６の送り出し動作の停止中に回転して容器２を自身の周方向に搬送する。この際、ローター１６の外面とローター設置空間１５の内面との間が気密にシールされているので、排出口１８を除くローター設置空間１５内が蒸し室１と略等しい内圧に保持される。
【００２６】
したがって、本実施例の穀物等の調理装置によれば、蒸し室１の内圧をより確実に維持することができるので、穀物の蒸し調理を目的の条件で正確に行なうことができ、味や外観の良い穀物等を確実かつ大量に得ることができる。また、受取機構１３の気密性が高いので、容器搬出路４における気密性を低レベルにすることができ、容器搬出路４を容器２の直径より短くして装置を小型化することが可能である。
【００２７】
なお、ローター１６は、搬入路入口７に適用しても構わない。
前記各実施例において、圧入機構および受取機構は前記した構成のものに限られず、他の構成のものであっても構わない。
【００２８】
以下、本発明の穀物等の調理装置の第３実施例を図５を参照して説明する。
本実施例の穀物等の調理装置は、前記第１実施例の穀物等の調理装置において、容器搬入路３および容器搬出路４にかえて図中符号２０の容器搬入路、２１の容器搬出路が設けられたものである。
前記容器搬入路２０および容器搬出路２１は、ともに容器２の直径の数倍（図５においては５倍）程度の長さに形成されている。これら容器搬入路２０および容器搬出路２１は、ともに容器２の外面が摺動可能な内面を有し、複数の容器２の外面と自身の内面との間に生じる流路抵抗によって、蒸し室１内外の圧力差を維持している。
【００２９】
本実施例の穀物等の調理装置によれば、容器搬入路２０、容器搬出路２１の流路抵抗によって、蒸し室１内圧が維持されるので、圧入機構９や受取機構１１として気密性の高い機構を設けない場合であっても、高い圧力維持効果を得ることが出来る。したがって、安価かつ構成の単純な装置によって、味や外観のともに良好な穀物等を容易に得ることができる。
【００３０】

The container 2 reaching the steaming chamber 1 is conveyed in the direction of the container unloading path 4 while being guided between the guide members 6a and 6a. At this time, the transport conveyor 6 operates in synchronization with the press-fitting mechanism 9 and transports the container 2 toward the container unloading path 4.
The container 2 sent to the carry-out path inlet 5 is sent out to the carry-out path outlet 10 through the container carry-out path 4 by the conveying force of the press-fitting mechanism 9 and the conveyer 6 while the outer surface is in sliding contact with the inner surface of the container carry-out path 4. The paper is discharged periodically by the receiving mechanism 11 at the road exit 10. The receiving mechanism 11 operates in synchronization with the press-fitting mechanism 9 and the transport conveyor 6. At this time, since the close contact between the outer surface of the one or more containers 2 and the inner surface of the container carry-out path 4 is always maintained, the high-pressure steam in the steaming chamber 1 does not leak through the container carry-out path 4.
[0022]
Therefore, according to the cooking apparatus for grains and the like, the container 2 slides and moves in and out of the steaming chamber 1 while maintaining close contact with the inner surfaces of the container carry-in path 3 and the container carry-out path 4. Leakage of high-pressure steam in the steaming chamber 1 due to passage is prevented, and the internal pressure of the steaming chamber 1 is maintained. Further, the press-fitting mechanism 9 and the receiving mechanism 11 have a simple configuration, are easy to manufacture, and are inexpensive.
As the container 2 moves, a volume of outside air corresponding to the gap between the containers 2 is carried into the steaming chamber 1, and the water vapor in the steaming chamber 1 having the same volume is carried outside the steaming chamber 1. Thus, the amount of water vapor discharged is extremely small, and the internal pressure of the steaming chamber 1 can be easily maintained.
[0023]
In addition, installation of the conveyance conveyor 6 in the steaming chamber 1 is not essential, and a flat plate, a bar, etc. may be sufficient if it is the structure which supports the container 2 so that a horizontal movement is possible.
Moreover, it is also possible to perform the process which reduces sliding resistance with the container 2 in the container carrying-in path 3 and the container carrying-out path 4 inner surface.
The cooking apparatus for cereals of the present embodiment can also be used for steaming cooking of cereals such as wheat, soybeans, and red beans as well as rice, as well as rice.
If the container carry-in path 3 and the container carry-out path 4 have a structure in which the steam in the steaming chamber 1 does not leak, there is no necessity to form the inner wall surface in a shape in close contact with the outer peripheral surface of the container 2, and lubricating oil or other contact You may make it contact with the container 2 via a structure. Further, if the length in the axial direction is increased, the leakage of steam is prevented by the flow path resistance, so that the closeness of the container carry-in path 3 and the container carry-out path 4 to the inner wall of the container can be lowered. is there.
