本文基于多孔介质的热湿交换原理,分析了影响粮堆调质通风效果的因素,提出了加湿调质通风的操作方法。测定了储粮加湿调质通风过程中粮堆内部的水分变化数据,得出了加湿调质通风过程中粮堆内部的水分变化,为加湿调质通风储粮技术的推广提供了基本依据。 Based on the principle of heat and moisture exchange in porous media, this paper analyzes the factors that affect the effect of conditioning and ventilation of grain heap and puts forward the operating method of humidifying and conditioning ventilation. The change of moisture inside the grain piles during the process of humidifying and ventilating stored grain was measured. The change of moisture inside the grain piles during the process of humidifying and ventilation was obtained, which provided the basic basis for the promotion of the technology of humidifying and ventilating grains.
