| 摘 要： | 利用空气回热器的热泵干燥试验装置,对稻谷干燥过程中的稻谷含水率、空气温度和相对湿度、干燥速率以及热泵能耗的变化进行了测试,并对影响干燥速率和能量回收率的因素进行了分析.分析结果表明,稻谷热泵干燥过程中,含水率和相对湿度均随着时间呈线性下降,而干燥箱内空气的温度随时间的变化较复杂;稻谷的干燥速率与空气相对湿度成反比,与空气温度成正比;稻谷含水率从31%降低到14%的平均能量回收率为34%,最大能量回收率为38.2%.

| Abstract: | This paper tests the variation of rice moisture content,air temperature and relative humidity,drying rate and heat pump energy consumption in rough rice drying process by applying the heat pump air-drying test equipment of air recuperator;and analyses the factors which affect the drying rate and energy recovery rate.The result shows that in rough rice drying process,moisture content and relative humidity decreased linearly with time,while the air temperature within the dryer changes with time and becomes mo... |
