我库 3- 2仓稻谷于 2 0 0 0年 11月 2 0日 - 12月18日期间进行通风降温处理 ,跟踪记录了通风的全过程 ,准确测定外界空气的温、湿度、粮温及稻谷水分的变化 ,为高大平房仓储粮机械通风降温提供了一些实践性依据。1　机械通风降温的原理由于粮堆温湿度与外界冷空气温湿度的差异 The warehouse of rice in Warehouse 3 and 2 was ventilated and cooled down from November 20 to December 18, 2000, and the whole process of ventilation was tracked and recorded to accurately measure the temperature and humidity of outside air, grain temperature and rice Moisture changes for the tall bungalow grain storage mechanical ventilation and cooling provides some practical basis. A principle of mechanical ventilation and cooling As the temperature and humidity outside the grain and cold air outside the temperature and humidity differences
