Description

【0001】
【発明の属する技術分野】
本発明は、穀物などの被加熱物を蒸気により殺菌又は調理する蒸し加工方法に関するものである。
【0002】
【従来の技術】
穀物、特に餅米を主材料とする米飯類の代表的なものとしては、おこわや赤飯等があり、その調理法は白米や炊き込みご飯等の他の米飯類の調理法と比べて以下のような相違点がある。
白米や炊き込みご飯等の調理法は、うるち米を主材料とした被加熱物を水分と共に鍋などの容器を使用して煮ること(炊飯)により加熱調理を行い、この場合被加熱物は、水分に浸された状態で加熱される。
一方、おこわや赤飯等の調理法は、餅米を主材料とした被加熱物を水蒸気により蒸すことにより加熱調理を行い、この場合被加熱物は水分には浸されず、上記に接触することで加熱されるという相違点がある。
【0003】
従来において、おこわや赤飯等の米飯類を蒸し加工により調理するには、穀物等の被加熱物を収納した蒸籠などの通水性容器を複数段重ね、上部に蓋をした状態で下方から蒸気を供給し、所定の時間被加熱物を蒸気と接触させることで蒸し加工を行っていた。
【0004】
また、被加熱物を連続的に加熱調理・殺菌する方法として、以下に述べるようなものが知られている。
蒸し加工されるべき被加熱物を収納容器内に水分と共に配置し、更に収納容器を内圧保持可能な複数の密閉容器内に収納する。
その後、該密閉容器内に蒸気を注入し、次いで該密閉容器を高温に維持された蒸し室内を順次搬送する。
密閉容器が所定の時間をかけて蒸し室内を搬送される間、蒸し室内の高温により密閉容器内の蒸気温度を保ちつつ、該密閉容器内の高温・高圧の蒸気により収納容器内の被加熱物を水分とともに加熱することで加熱調理・殺菌を行う。
【0005】
この調理方法によれば、無端状に形成された搬送機構により密閉容器を巡回させつつ、上記の工程を行うことで、連続的に被加熱物を加熱調理・殺菌することができる。
また、密閉容器を内圧保持可能としたことで、密閉容器内の内の蒸気圧を1気圧以上とすることができ、100度以上の高い蒸気温度を得ることができる。これにより調理時間を短縮することができ、効率的な連続調理が可能である。
また、密閉容器内の温度や蒸気圧にばらつきを生じずに均一な仕上がりの
製品を得ることができる。
【0006】
【発明が解決しようとする課題】
ところで、上述した2つの加工方法の内、前者の被加熱物を蒸籠などの通水性容器を使用して蒸し加工する方法によれば、被加熱物は水分に浸されない状態で上記により加熱されるので、本来の蒸し加工を行なうことができる。
しかし、100度以上の蒸気温度を得ることができないため、蒸し調理に要する時間が長くかかり、時間効率が低いという問題があった。
また、容器を複数段重ねて調理するため、生産ラインでの連続調理化が困難であるという問題があった。
また、上段に配される通水性容器と下段に配される通水性容器との間の温度や蒸気圧が均一にならないことがあり、製品の品質にばらつきが生じるという問題があった。
【0007】
後者の被加熱物を連続的に加熱調理・殺菌する方法では、蒸気を高温・高圧にしたことで調理時間を短縮化することができ、効率的な連続調理ができる。
しかしその一方では、蒸気が高温・高圧であるために調理中の被加熱物に水分が不足して、米飯類等の場合は、芯の残った仕上がりになってしまうという不都合あり、収納容器内に被加熱物とともに水分を入れて調理することが不可欠であった。
このため本来の蒸し加工を行うことができず、蒸し煮加工に近い加工となる。
【0008】
本発明は、上記事情に鑑みてなされたもので、加工時間の短縮化、連続的加工、製品品質の均一化、良質化を実現する蒸し加工方法を提供することを目的とする。
【0009】
【課題を解決するための手段】
本発明の蒸し加工方法では、上記課題を解決するために、以下の手段を採用した。
請求項1記載の蒸し加工方法によれば、蒸し加工されるべき被加熱物を通水性材料により構成されかつ上部に開口部を備える通水性容器内に配置し、該通水性容器を内圧保持可能な密閉容器内に収納する。
その後、密閉容器に高温・高圧の蒸気を注入して、該蒸気により被加熱物を加熱しつつ、密閉容器に設けられた熱水供給装置により被加熱物に水分を供給し続けることにより蒸し加工を行う。
【0010】
この蒸し加工方法では、加熱処理と平行して密閉容器に設けられた熱水供給装置により被加熱物に水分を供給し続け、供給された水分が被加熱物に吸収され、被加熱物の水分不足を防いで目的の含水分率を得ることができる。
この際、被加熱物が吸収しきれない水分は容器の底面を構成する通水性材料を通過して下方に落下するため、被加熱物は水分に浸されることなく加熱されて本来の蒸し加工の状態が維持される。
【0011】
熱水供給装置から被加熱物に供給される水分は、水以外にも、例えば味付けのための調味液や着色のための着色液であっても良い。
【0012】
請求項2記載の蒸し加工方法によれば、蒸し加工されるべき被加熱物を通水性材料により構成されかつ上部に開口部を備える通水性容器内に配置し、該通水性容器を内圧保持可能な複数の密閉容器内に収納する。
その後、密閉容器内に蒸気を注入し、次いで該密閉容器を高温に維持された蒸し室内を順次搬送する。
密閉容器が蒸し室内を移動する間、密閉容器内の蒸気の高温・高圧により被加熱物を加熱しつつ、密閉容器に設けられた熱水供給装置により被加熱物に水分を供給し続けることにより蒸し加工を行う。
【0013】
この蒸し加工方法では、密閉容器内に収納した被加熱物を搬送機構により順次搬送しながら被加熱物の蒸し加工を行うことで、本来の蒸し加工の状態を維持したまま効率的な連続加工を行うことが可能となる。
【0014】
【発明の実施の形態】
以下、本発明の実施の形態を図面を参照して説明する。
図1および図2は本発明の蒸し加工方法を実施するための蒸し加工装置を示す図であって、図において、符号1は蒸し加工装置である。
蒸し加工装置1は、蒸し室2と、穀物等の被加熱物をその内部に収納する通水性容器3を収納する密閉容器4と、該密閉容器4を蒸し室2の搬入口5から搬出口6に向けて順次搬送する搬送機構7とから構成されている。
【0015】
蒸し室2は、内圧保持可能に形成された大型の筺体であって、所定温度に加熱した蒸気を蒸し室2の内部に供給する蒸気供給機構2aが接続される。
また、蒸し室2には、密閉容器4に高温・高圧の蒸気を注入する蒸気注入機構8が設けられている。
【0016】
通水性容器3は、その上部が開口部3aとなっており、底部および周壁部は穀物を通過不能にすると共に蒸気または液体が通過できるように、例えば、メッシュ状に形成された耐熱性材料により構成されている。
【0017】
密閉容器4は、図2に示すように、容器本体4aと、この容器本体4a内の蒸気圧を所定値以下に維持すると共に、容器本体4a内に滞留した水も排出可能な圧力調節弁9と、前記蒸気注入機構8から注入される蒸気を容器本体4aに導入する蒸気注入管10とを備えている。
蒸気注入管10には、容器本体4a内への蒸気注入を許し、かつ逆流を防止する逆止弁10aが設けられている。
容器本体4aには、通水性容器3を該容器本体4aの上下方向の中間部において支持する板状の通水性材料により構成された支持部材11が設けられており、この支持部材11の下方には蒸気注入管10が容器本体4aの壁部を貫通して設けられている。
また、容器本体4aの内部上方には、熱水供給装置wからの水分を通水性容器3内の被加熱物に供給する熱水供給管12が設けられている。
【0018】
搬送機構7は、無端状に形成されたチェーン13と、該チェーン13が卷装される4カ所のスプロケット14と、該チェーンを回動させる駆動機構15とを備えて構成されている。
スプロケット14の内の2つは、搬入口5と搬出口6のそれぞれ外側において、搬入口5と搬出口6との配置軸線に沿って配置され、チェーン13を搬入口5と搬出口6との配置軸線にそって張設するようになっている。
チェーン13上には、所定の間隔を開けて複数の密閉容器4が載置されている。
【0019】
以下、この蒸し加工装置1を使用して、おこわや赤飯を蒸し調理する方法を説明する。
まず、蒸し室2内に蒸気供給機構2aから蒸気を導入し、蒸気注入機構8を蒸気注入が可能な待機状態としておく。
そして、餅米を主体とした被加熱物を、予め計量して所定量とし、通水性容器3内に配置した後、該通水性容器3を蒸し室2の外部に位置している密閉容器4内に収納する。
【0020】
この状態で、駆動機構15を起動させ、チェーン13を回動させる。
チェーン13の回動により、密閉容器4が蒸し室2に設けられた蒸気注入機構8の位置まで搬送され、この位置で、蒸気注入機構8により密閉容器4内に蒸気注入管10を介して所定の温度・圧力の蒸気が注入される。
この際、密閉容器4内の蒸気圧は1気圧以上の高圧となり、蒸気温度も100度以上の高温となる。
【0021】
密閉容器4への蒸気の注入を終えたら、搬送機構7を再び作動させ、所定の時間をかけて密閉容器4が搬出口6に向かって搬送される。その間に被加熱物は、蒸気注入機構8によって密閉容器4内に充填される蒸気の高温・高圧によって加熱される。
該加熱処理と平行して、熱水供給装置wから密閉容器4に設けられた熱水供給管12を介して被加熱物に調味料、着色料を含んだ水分が供給される。
このため、被加熱物は、100度以上の蒸気によっても水分が不足しない状態を維持しながら蒸し加工され、同時に調味・着色される。
【0022】
この際、被加熱物が吸収しきれない調味液は、通水性容器3の容器の底壁部を通過して下方に落下するため、通水性容器3内には滞留せず、被加熱物が水分に浸されることはない。
【0023】
蒸し室2内は、高温の蒸気で満たされているので、密閉容器4が蒸し室2内を搬送される間に密閉容器4は継続的に加熱され、密閉容器4内の蒸気温度は高温に維持される。
密閉容器4内の温度上昇等によって、密閉容器4内の蒸気圧が上昇しすぎた場合には、密閉容器4に設けられた圧力調節弁9から蒸気が放出されて、蒸気圧が安定に維持される。
【0024】
所定の時間をかけて密閉容器4が蒸し室2内を搬送され、密閉容器4が搬出口6から搬出されたとき、密閉容器4内の蒸気圧を大気圧まで減圧し、通水性容器3を取り出して製品としてのおこわや赤飯を得る。
【0025】
おこわや赤飯を取り出した後の密閉容器4は、被加熱物を配置した通水性容器3を収納した後、再び蒸し室2へと搬送され上記した工程を繰り返すことで連続的に蒸し加工を行う。
【0026】
この蒸し加工方法によれば、密閉容器4内に充填される100度以上の高温の蒸気により被加熱物を加熱し、かつ、被加熱物に不足する水分を被加熱物が浸らない状態で供給することで、短時間で本来の蒸し加工を行うことができ、製品品質の均一化、良質化を図ることができる。
【0027】
また、密閉容器4内に収納した被加熱物を搬送機構7により順次搬送しながら被加熱物の蒸し加工を行うことで、本来の蒸し加工の状態を維持したまま連続的に蒸し加工を行うことができる。
【0028】
なお、本実施の形態においては、通水性容器3をメッシュ状に形成されていることとしたが、他の形態として、例えば、水分および蒸気が通過自在であり、かつ、被加熱物を通過不能とする大きさの孔または溝が形成された容器としても良い。
【0029】
なお、蒸し室2内において、搬入口5と搬出口6との間で相対的に異なる複数の温度領域を形成した場合には、密閉容器4がこれら温度領域を順次通過することにより、より複雑な加工も可能である。
【0030】
【発明の効果】
本発明によれば、以下の効果を得られる。
請求項1記載の蒸し加工方法によれば、加熱工程中に被加熱物に不足する水分を供給することで、短時間で効率的な本来の蒸し加工を行うことができ、製品品質の均一化、良質化を図ることができる。
【0031】
請求項2記載の蒸し加工方法によれば、密閉容器内に収納した被加熱物を搬送機構により順次搬送しながら被加熱物の蒸し加工を行うことで、被加熱物を効率的な連続加工できるという効果が得られる。
