我库地处湖北荆州,位于长江以南,属第五储粮生态区。夏季高温时段,仓库屋面、墙身吸收的大量热能传递到仓内,导致粮温上升。受外温影响最大的表层粮温最高可达35℃以上,使储粮呼吸速率提高,品质劣变速度加快,严重影响粮食储藏品质,给企业带来不应有的损失。我们根据库区的自然 My library is located in Jingzhou, Hubei Province, located south of the Yangtze River, is the fifth grain reserve ecological zone. Summer high temperature period, the warehouse roof, a lot of heat absorbed by the body wall to pass into the warehouse, leading to food temperature rise. The surface grain temperature, which is most affected by external temperature, can reach as high as above 35 ℃, which can increase the respiration rate of grain storage and speed up the deterioration of quality, seriously affecting the grain storage quality and bringing undue losses to the enterprise. We are based on the nature of the reservoir area
