在低温季节利用高于仓内粮堆一定范围的大气湿度进行机械通风降温,不但可以使储粮较长时间处于低温或准低温的状态,有效抑制害虫及微生物的生长繁殖和危害,减少化学药剂的熏蒸,有效预防和消除储粮的发热霉变现象,延缓粮食的品质劣变,确保粮情稳定,达到绿色安全储粮的目的,还可以减少在机械通风降温过程中的粮食水分损耗,以免造成不必要的经济损失。 In the low temperature season, the use of air humidity higher than the warehouse within a certain range of mechanical ventilation and cooling, not only can make a long time stored grain in a state of low temperature or quasi-low temperature, effectively inhibit the growth and reproduction of pests and microorganisms and hazards, reduce chemical agents Fumigation, effectively prevent and eliminate the phenomenon of mildew of stored grain, delay the deterioration of food quality, ensure the stable grain condition and achieve the goal of green and safe grain storage, and also reduce the loss of grain moisture during the process of mechanical ventilation and cooling to avoid Cause unnecessary economic losses.
