低温储粮可以有效延长粮食的安全储存期,延缓粮食陈化速度,并能有效控制虫、霉对粮食的危害,减少化学药剂对粮食的污染,降低保管费用,因此它是一种行之有效的绿色环保储粮技术。长期以来,广大仓储工作者通过机械通风或制冷等多种手段,有效降低粮温。但如何长期保持粮堆低温状态 Low-temperature grain storage can effectively prolong the safe storage period of grain, slow down the aging of grain, and effectively control the harm of insects and mildew to grain, reduce the pollution of foodstuff by chemical agents and reduce the storage cost, so it is effective Green food storage technology. For a long time, the majority of storage workers through mechanical ventilation or cooling and other means to effectively reduce food temperature. However, how to maintain the low temperature status of the grain crops for a long time
