摘要
研究了热泵辅助太阳能烘干鲜枣设备的技术原理并进行了参数设计,确定了9块空气集热器和12匹热泵。通过试验得出鲜枣的干燥规律分为4个阶段:预热升温阶段、蒸发阶段、干燥完成阶段和降温排湿阶段。最后根据结果进行数据处理,绘出鲜枣的干燥曲线,并得出4项试验结论。
Technical principle and parameters of heat pump-assisted solar drying equipment for fresh jujube were studied,9 air collectors and a heat pump with the power of 12 horsepower were determined. Drying rule of fresh jujube was explored by experiment,and it was divided into four stages： preheating stage,evaporation stage,drying completion stage and stage of dehumidification. Finally,drying curve of fresh jujube was drawn according to results and four experimental conclusions were obtained.
