摘要
为了解决农产品干燥过程中能耗高、品质差等问题,研制了一种微波热泵联合干燥机,对该机的整机结构、工作原理和关键部件做了介绍分析,并以金针菇为原料进行了微波热泵联合干燥机的最佳干燥工艺探究试验。试验表明:在微波功率13.3k W、热风温度65℃、传送带转速0.6m/s时,干燥后的金针菇含水率12.37、复水比3.124、色差81.8,满足干燥要求且优于其他组合。该研究可为微波热泵联合干燥机的研制及金针菇的干燥提供参考。
In order to solve the high energy consumption and poor quality problem of the agricultural products in the process of drying,The structure,working principle and key components of the machine are introduced. and take mushroom as raw material to explore the best dry process of microwave heat pump drying machine。The experiment results show that the microwave power 16 k W,hot blast temperature 65℃,the conveyor belt speed 0. 6 m / s,the moisture content of dried lily flowers 12. 37,rehydration ration 3. 124,color 81. 8,meeting the needs of dry request and is superior to the other combination,the paper for the development of microwave heat pump drying machine and needle mushroom dry to provide the reference.
