日本开发试用的新的大米保鲜储藏设备由冷却装置，通风管道、温度自控装置等构成。大米采用散装方式储藏。大米入仓后．冷却装置启动后产生冷气，并通过散布在大米中的通风管道向大米中喷放冷气．使仓内大米全部冷却。当白内温度降至15℃、湿度为70％时，冷却装置就会自动关闭 Japan developed a new trial storage of rice by the cooling device, ventilation ducts, temperature control devices and other components. Rice is stored in bulk. After the rice into the warehouse. Cold air is generated when the cooling unit is started and the cold air is blown into the rice through the ventilation ducts scattered in the rice. So that all the warehouse to cool the rice. When the white temperature dropped to 15 ℃, humidity is 70%, the cooling device will automatically shut down
