The device is a high-tech energy-saving heat pump dryer, the cavity in the outdoor box body 5 is a cavity which can be contacted with the outside air, the circulating fan 3 draws air outwards (the first compressor 8a is started), the outside dry air enters the cavity in the outdoor box body 5 through the second evaporator 7 and is drawn out through the fan 3, and the outer cavity air circulation is formed. The second evaporator 7 is communicated with the second condenser 10a, the refrigerant absorbs a great deal of heat (the refrigerant is changed from liquid to gas) at the second evaporator 7, the refrigerant is compressed by the compressor to be changed into high-temperature high-pressure gas, then the refrigerant releases heat (the refrigerant is changed from gas to liquid) at the second condenser 10a, and the material is heated by the drying fan 2; this is a class i heat cycle system (external cycle), i.e. the second evaporator 7 is used to transfer the heat in the outside air to the drying room. Stage ii heat cycle system (second compressor 8b start): when the material is heated, a large amount of damp and hot air is generated in the drying room, the refrigerant absorbs a large amount of heat at the first evaporator 9 (the liquid state of the refrigerant is changed into the gaseous state), so that the temperature of the outer wall of the first evaporator 9 is reduced, the condensation point of steam is reached, the damp and hot air is condensed in a large amount at the outer wall of the first evaporator 9, the damp and hot air is changed into the liquid state to be discharged, and the aim of moisture removal is fulfilled. Meanwhile, the gaseous refrigerant is compressed by the compressor to become a high-temperature high-pressure gaseous state, the gaseous refrigerant is changed into a liquid state at the first condenser 10b to emit heat, and the material is heated by the drying fan 2 to form heat circulation (internal circulation for dehumidification); thus, two stages of heating are performed.
When the temperature in the drying room meets the task requirement, the first compressor 8a stops working and does not convey heat.
