My county is the food transferred to the region, finished grain (rice) inventory, annual spring before, we generally use plastic film cover for rice and other finished food five sealed sealed storage. This method, which can effectively control the physiology of grain, the activities of caterpillars and microorganisms, and delay the aging process, plays a significant role in the summer of safety.
