摘　　要：结合本地气候与储粮特点进行高大钢板平房仓地上笼机械通风技术应用试验。结果表明 ,在冬季干冷天气相对较短的时间内 ,采用间歇式机械通风 ,能够取得较好的通风降温效果 ,其单位能耗可控制在 0 .0 4kW·h/℃ t以内。粮温梯度由 1℃ /m降为 0 .4℃ /m粮层厚度 ,粮食水分梯度由 0 .15 % /m降至 0 .0 5 % /m ,粮堆温度和水分分布更加均匀 。Mechanical ventilation with the cages on the ground was tested in large steel warehouse.The results showed that intermission mechanical ventilation in cold and dried weather in winter can gain good effect on lower temperature,and its energy consumption per unit can controlled in 0.04kW·h/℃·t.The difference of temperature decreased from 1℃/m to 0.4℃/m,and the difference of moisture content decrease from 0.15%/m to 0.05%/m,so the safety of grain was improved.
