摘　　要：温差和露点是储粮结露的两个重要因素,根据成品粮大米接卸期间的大气温湿度、仓内温湿度、粮食温度条件以及大米的水分等情况,梳理成品粮大米结露的原因,利用粮堆露点近似值检查表、粮食绝对湿度曲线图和大气绝对湿度曲线图等相关图表,总结出预测粮堆结露的主要方法,并提供可行有效的处理措施,对安全储存成品粮具有积极意义。Temperature difference and dew point are two important factors for moisture condensation of the storage grain.According to the large temperature humidity,storage temperature and humidity,grain temperature conditions and rice moisture during the discharge period of the finished grain rice,the reasons for moisture condensation were concluded.Using the relevant charts such as grain pile dew point approximation checklist,grain absolute humidity graph and atmospheric absolute humidity map,the main method of grain pile dew predicting were summarized and the feasible and effective treatment measures were provided which has positive significance for the safe storage of finished grain.
