The heat pump dryer consists of a compressor-heat exchanger (internal unit)-throttle-heat absorber (outer unit)-compressor and other devices to form a circulation system (host + drying room).
The refrigerant circulates in the system under the action of the compressor. It completes the gaseous boosting process in the compressor (temperature up to 115 ° C), it enters the internal machine to release high temperature heat to heat the air in the drying room, while being cooled and converted into a liquid liquid, when it runs to the outside machine After that, the liquid rapidly absorbs the heat and evaporates again into a gaseous state, and the temperature drops to minus 20 ° C - 30 ° C, at which time the air around the heat sink will continuously transfer heat to the refrigerant. The continuous circulation of the refrigerant realizes the transfer of the heat in the air to the temperature of the air in the heating room in the drying room.
1. The air energy heat pump dryer can effectively ensure the nutrients, health and environmental protection.
2. safe and reliable operation: the whole system runs without the danger of flammable, explosive, poisoning and short circuit which may exist in the traditional dryer (fuel, gas or electric heating), and is a safe and reliable fully enclosed drying system.
3. Long service life and low maintenance cost: It is developed on the basis of traditional air-conditioning technology. It has mature technology, stable and reliable performance, long service life, safe and reliable operation, automatic manual operation and intelligent control.
