PROBLEM TO BE SOLVED: To provide a manufacturing method of frozen cooked rice for individual eating, using a low-protein polished rice having difficulty in normal rice cooking, capable of improving the taste of cooked rice, by continuous production.SOLUTION: The manufacturing method of frozen cooked low-protein polished rice includes the successive steps of: (2) filling a container having an upper opening with a specified quantity of low-protein polished rice (4) adding a specified quantity of rice-cooking water into the container (5) rapidly heating the rice and rice-cooking water under pressure with microwaves (7) reducing the pressure to atmospheric pressure for preliminary cooking and adding a specified quantity of secondary rice-cooking water into the container (8) finish cooking and (9) freezing the cooked rice in the container. The container for rice cooking can be transported by a container transport device 1. The method includes the successive steps of: transporting the container (2) rice grain charging (4) primary water addition (5) heating by microwaves under pressure (7) secondary water addition (8) finish cooking and (9) freezing.COPYRIGHT: (C)2015,JPO&INPIT【課題】通常の炊飯が困難と言われる低たん白米を対象とした個食用の冷凍米飯の製造方法で、米飯の食味を向上させ、かつ、連続生産する。【解決手段】上方が開口した容器内へ所定量の低たん白米を充填し2、容器に所定量の炊飯水を加水した後4、米及び炊飯水を加圧下でマイクロ波により急速加熱した後5、大気圧まで減圧する予備炊飯を行い、さらに、容器内へ所定量の炊飯水を二次加水する7とともに仕上炊飯し8、次いで、容器内の米飯を冷凍する9。前記炊飯用の容器は容器搬送装置1によって移送可能となし、該容器搬送過程に米粒充填工程2、一次加水工程4、加圧マイクロ波加熱工程5、二次加水工程7、仕上炊飯工程8及び冷凍工程9を順次備えてなる低たん白米の冷凍米飯製造方法。【選択図】図2
