ABSTRACT:
A sterile-packed rice product is produced in a system including a rice filling device that fills an individual tray with a predetermined quantity of washed and soaked rice; a sterilization chamber that substantially air-tightly contains one or more of arrays of the trays with rice for sterilizing the rice with high-temperature pressurized steam introduced into the chamber; a water filling device that fills the trays with the sterilized rice with a predetermined quantity of water necessary for steam rice-cooking; a steam rice cooker that cooks the rice with a steam; and a sealing device that lids air-tightly that trays with the cooked rice. A clean booth surrounds a conveyor conveying the trays from the steam rice cooker to said sealing device, thus providing a predetermined cleanliness over an area covering at least a conveying path of the trays from an exit of the steam rice cooker to the sealing device. An intermittent conveyor is preferably used to intermittently conveys the arrays of the trays throughout the rice filling device and the sterilization chamber. Preferably, high temperature pressurized steam is intermittently flushed into the sterilization chamber for sterilization of the packed rice.
