热泵间歇干燥是一种能耗低﹑干燥产品质量高的新型干燥方式，深入开展其工艺优化研究非常必要。以白菜种子热泵干燥为例，建立由干燥空气传热与传质模型﹑种子传热与传质模型组成的干燥模型，根据模拟结果确定了描述热泵间歇干燥性能的机组性能指标和干燥产品性能指标，运用模糊层次分析法获得热泵机组性能和干燥产品性能综合最优的热泵间歇干燥方式。结果表明，对白菜种子而言，干燥周期为3000 s﹑比例系数为1∕6的热泵间歇干燥的综合性能最优。

Heat pump intermittent drying(HPID) is an energy_efficient process with high quality products.It is necessary to carry on a further research on its optimal process.A heat pump drying model was built for the cabbage seed with heat pump drying.It included the heat and mass transfer models of the drying air and those of the cabbage seed.The simulation results were used to form the heat pump unit performance index and the dried product performance index.The fuzzy analytical hierarchy process method was used to obtain the optimal HPID process excelling in both the heat pump unit performance index and the dried product performance index.Results show that the HPID with drying period of 3000 s, proportion of 1 ∕6 can obtain the best comprehensive performance for the cabbage seed.
