摘　　要：根据竹笋热泵单因素干燥试验研究,研制了分时段自动控制竹笋干燥过程参数的热泵干燥设备,干燥温度为35~70℃,相对湿度为10%~90%,除湿能力为50kg/h(温度50℃,相对湿度50%);实际应用表明,装载量为1500~1800kg时,干燥周期为36~38h,除湿能力为45~65kg/h,能满足实际生产需求,干燥能耗与燃料热风干燥相比降低了50%以上,品质良好,设备适用于对干燥品质要求较高的果蔬批量加工生产。According to the single factor drying of bamboo shoot with heat pump,developed a sub-automatic control of bamboo drying process parameters of the heat pump drying equipment. Operating temperature was 35~70 ℃,relative humidity was 10%~90%,dehumidification capacity was 50 kg/h(50 ℃,RH 50%). The application showed that when the loading was 1 500~1 800 kg,the drying period was 36~38 h,the actual dehumidification capacity was 45~65 kg/h,which meet the actual production needs. Drying energy consumption than the fuel hot air drying more than 50% energy saving. Dry and good quality. The equipment was also suitable for drying high quality requirements of batch processing fruit and vegetable production.
