一、粮食平衡水分的概念:粮食在贮藏期中的水分,是随着空气中温、湿度的变化而变化.当粮食从周围环境中吸收水分的速率相等于粮食从周围环境中散失水分的速率时,则粮食处于与环境平衡状态,这种处于平衡状态时的水分,叫做平衡水分或湿度平衡.与粮食周围空气相平衡的相对湿度叫做平衡相对湿度.各种粮食的平衡水分含量随着温度和 First, the concept of food balance of water: food in the storage of water, with the air temperature and humidity changes.When the food from the surrounding environment to absorb water at a rate equal to the rate of water loss from the surrounding environment, The food is in a state of equilibrium with the environment, which is called equilibrium water or moisture balance, and the relative humidity that equilibrates with the air around the food is called the relative humidity of equilibrium. The equilibrium moisture content of various grains varies with temperature and
