To provide a sterilization processor for cereals that extremely efficiently supplies cereals, and sterilize all the outer peripheral surfaces of cereals through a simple mechanism and improves the preservability, by providing an ultraviolet sterilization irradiation means or the like installed above a sterilization processing conveyer path.
This device has a hopper device 16 for throwing in cereals, conveying means provided successively to this hopper device 16 so as to convey thrown-in cereals on a sterilization processing conveyer path 20a while rotating them, and ultraviolet sterilization irradiating means such as a ultraviolet sterilizing radiator 44 provided above this sterilization processing conveyer path 20a. In this case, it is preferable that the conveying means is composed of a lot conveyer rollers 38 arranged at intervals so as not to drop cereals.
