Working principle of heat pump dryer:

The working principle of a heat pump dryer is to use the inverse Carnot principle. The refrigerant (mostly mixed refrigerant) is compressed by the compressor and becomes a high-temperature and high-pressure gas, with a temperature of up to 100-110 ℃. The high-temperature gas enters the heat exchanger (condenser) through the pipeline (copper tube), and then is sent to the drying room by the fan to heat and dry the materials. The moisture of the heated materials in the drying room evaporates, and is discharged outside the drying room through a dehumidifier or dehumidifier, thus achieving the purpose of drying.

Characteristics of heat pump dryer:

1. Easy installation: Easy to install, takes up less space, and can be installed indoors or outdoors.

2. Energy saving: With only a small amount of electrical energy, it can absorb a large amount of heat in the air, which is 75% more energy-efficient than electric heating dryers; 66% more energy-efficient than fuel and gas drying equipment; 30% more energy-efficient than coal-fired dryers, 1 kWh of electricity is equivalent to 4 kWh of electricity.

3. Environmental Protection: The combustion and emissions of ********* meet food hygiene standards and are a sustainable and environmentally friendly product.

4. Safe and reliable operation: The entire system operates without the risks of flammability, explosiveness, poisoning, short circuit, etc. that may exist in traditional dryers (fuel, gas, or electric heating), making it a safe and reliable fully enclosed drying system.

5. Long service life and low maintenance cost: It is developed on the basis of traditional air conditioning technology, with mature process technology, stable and reliable performance, long service life, and safe and reliable operation.

6. High degree of intelligence: adopting PLC computer intelligent control, the drying process can be set according to the characteristics of the material, without the need for manual duty, and can operate continuously for 24 hours.

7. Wide applicability: Suitable for all products or materials that require drying, dehumidification, and dehydration in various industries.
