Manufacturing process being simple, the retort boiled rice which is superior in appearance the retort boiled rice manufacturing system which it can be consistent can produce from the raw United States is offered. While as forming alpha conversion layer in the surface section of the raw United States, in order to designate the center as vesicular, the said raw United States compressed suchima mechanism and the description above which steam it heats process under pressurizing with the conveyer to convey the steaming/evaporation United States which was processed, removing surface water amount, to monad steaming/evaporation American monad conversion mechanism and to aforementioned monad which it converts weighing the steaming/evaporation United States of equivalent to one packing which is converted, as it fills up the steaming/evaporation United States in quantitative filling up mechanism and the container which it fills up in the container in the container where the said steaming/evaporation United States fills up, furthermore, at least, the preparation liquid of the quantity which is necessary for dipping water absorptionAnd so on filling up with the liquid and the vapor in order, to guarantee the head space while packing mechanism and the description above which seal specified frequency reversing the packing body of the container which is sealed, dipping water absorption mechanism and the aforementioned preparation liquid which make the preparation liquid the steaming/evaporation United States absorb the retort sterilization device which it heats processes and, it had the steaming/evaporation United States which absorbs water to the center.製造工程が簡略で、外観に優れるレトルト米飯を生米から一貫製造できるレトルト米飯製造システムを提供する。生米の表層部にアルファー化層を形成するとともに、中心部を多孔状とするために、該生米を加圧下で蒸気加熱処理する加圧スチーマー機構と、前記処理された蒸米をコンベアで搬送しつつ、表層水分を除去して単粒化する蒸米単粒化機構と、前記単粒化された一包装分の蒸米を計量して容器に充填する定量充填機構と、容器に蒸米を充填するとともに該蒸米が充填された容器に、さらに、少なくとも、浸漬・吸水に必要な量の炊飯液などの液状物とヘッドスペースを確保するための気体とを充填して封止する包装機構と、前記封止された容器の包装体を、所定回数反転させつつ蒸米に炊飯液を吸収させる浸漬・吸水機構と、前
