摘要
利用已开发的谷物低温干燥模拟程序以及北京地区1968～1993年的气象数据,对北京地区玉米低温干燥进行了模拟研究。分析了风量、玉米初始含水率、干燥作业开始日期、逐年气象条件和谷床厚度对玉米低温干燥的影响。给出了不同条件下北京地区玉米低温干燥的风量推荐值。
With a computer simulation programe and the weather data from the year 1986 to 1993 in Beijing area,simulation study on the low temperature corn drying is carried out.The influence of airflow rate,initial moisture content,har- vest date,annual weather condition and grain bed depth on the drying performance is investgated.The recommendations for airflow rate under different conditions are given.
