机械通风是保存储藏谷物市场品质的常用处理方式,它之所以能够在谷物仓库中逐步推广,就是因为采用通风设备处理的谷堆,能够在不移动的情况下,达到保存市场品质的目的。而且谷物的损耗和保管费用也比较低。经过长期实践,人们发现,用机械通风处理谷物,具有五个方面的作用:(1)机械通风能防止和抑制谷堆中霉菌的繁殖和仓储害虫的活动。(2)机械通风能够阻止和消除谷堆内水分迁移现象和降低一定的水分。(3)消除和排散储藏谷物中的气味。(4)采用通风投放熏蒸剂,可以获得比重力法熏蒸更加理想的效果。(5)通风能够在短期内控制高水分粮的品质劣变速度,可作为一项抢救高水分粮的应急措施。
Mechanical ventilation is a commonly used method of preserving the quality of the stored grain market. The reason why it can be gradually popularized in cereal warehouses is that the ventilated grain heap can be used to preserve market quality without moving. And cereal loss and storage costs are relatively low. After a long period of practice, it has been found that the treatment of cereals with mechanical ventilation has five functions: (1) Mechanical ventilation prevents and inhibits the growth of fungi in the heaps and the storage of pests. (2) Mechanical ventilation can prevent and eliminate the moisture migration in the heap and reduce the water content. (3) eliminate and disperse the smell of stored grain. (4) the use of ventilation put fumigant, you can get better than the gravity fumigation effect. (5) Ventilation can control the quality deterioration of high-moisture food in a short period of time and can be used as a emergency measure to save high-moisture food.
