The patent mainly achieves the advantages of good drying effect and energy saving by setting a compressor, a condenser, a throttling device, an evaporator, a high-temperature drying chamber, a dew point meter, a low-temperature drying chamber, a circulating cooling water coil, a microwave source and an infrared source. However, the wind force of the internal fan of the traditional normal temperature heat pump type fruit and vegetable drying device cannot be adjusted.
