PROBLEM TO BE SOLVED: To provide a method and apparatus for producing quick-cooking storage rice, capable of wash sterilizing rice without using water, shortening water absorption time, enabling miniaturization, simplification and space-saving, and enabling easily obtaining good-quality boiled rice.SOLUTION: This method for producing the quick-cooking storage rice comprises receiving each prescribed amount of rice from a rice storage tank 2 on a net, wash sterilizing through spraying air, fog and 100-350°C atmospheric superheated steam to the rice, exposing the rice to 30-48°C hot water for 20 s-10 min, letting the rice absorb water followed by draining, and blowing in saturated steam of 0.25-1.5 kg/cm2 from the hole 6c of a tank 6 which stores a fixed amount of the rice followed by steaming. Furthermore, the method comprises receiving the steamed rice in a bag 10 and putting into an opened container 11 as it is followed by closing the container 11, keeping a vacuum condition of &ge690 mmHg for 10 s-30 s, putting aseptic air into the container 11 to bring to atmospheric pressure, sealing the bag 10 followed by taking out the bagged steamed rice from the container 11, ripening pregelatinized rice starch, and obtaining pregelatinized treated rice in a single-grained condition.COPYRIGHT: (C)2008,JPO&INPIT【課題】水を使わず米を洗浄殺菌し吸水時間も短縮でき、小型化、単純化及び小スペース化を図れ、良質の米飯を容易に得る早炊き貯蔵米の製造方法及びその装置を提供する。【解決手段】米貯留タンク2から米を所定量ずつネット上に受け入れ、エアー及び霧並びに100~350℃の常圧過熱蒸気を吹き付けて洗浄殺菌し、その米を30~48℃の湯に20秒間~10分間さらして吸水させ水切りして、その米を一定量貯留するタンク6の孔6cより0.25~1.5kg/cm2の飽和蒸気を吹き込んで蒸し、蒸し米を袋10にて受け入れ開封のまま容器11内に入れて該容器11を閉じ690mmHg以上の真空状態を10秒間~30秒間保持するようにしたあと容器11内に無菌エアーを入れ大気圧とし袋10を密封して容器11内から袋入り蒸し米を取り出して、アルファー化した米澱粉を熟成させて単粒化した状態のアルファー化処理米を得ることで、上記課題を達成する。【選択図】図1
