Heat Pump Drying Room

Air heat pump dryer is a new type of drying device based on the principle of reverse Carnot cycle. It forms high-temperature gas by adding refrigerant to the compressor, releases heat through the condenser, and absorbs environmental heat energy through the evaporator to achieve material dehydration and drying. The device consists of a heat pump host, a circulating air duct, a dehumidification system, etc.

The main engine ofthe heat pump drying room is the air energy heat pump, which adopts the inverse Camot principle to absorb heat from the surrounding environment and transfer it to the dried materials.

WORKING PRINCIPLE

The working principle of the heat pump drying room is that the refrigerant is compressed by the compressor to become a high- temperature and high-pressure gas, which enters the condenser for heat release, and the heat from the condensation heat release is sent to the drying room by the circulation fan, and the air in the drying room is heated (the maximum air temperature can reach 75 ° C). With the rise of air temperature, the moisture in the drying materials will gradually evaporate, and then the fresh air dehumidification system will discharge the moisture, so as to achieve the drying effect.

Technical Charateristics

1.Environmental friendly.

Material drying requires not only improving product quality and saving energy, but also being environmentally friendly. In theraditional baking room, combustible materials are used to barbecue, and toxic gases such as carbon monoxide are emited, which is harmful to hum an health; in the whole process, Heat pump drying room realizes zero emission and real green drying.

2.Energy saving.

Traditional baking houses use artificial combustion materials to heat up, which requires a large number of labor to purchase or process fuel; while heat pump drying houses use self heating curve control without manual intervention, and one person can take care of multiple heat pump drying houses at the same time. With the promotion of intensive baking houses, batch heat pump drying has achieved centralized control, which is more conducive to labor liberation.

3.The drying parameters are easy to control and can be adjusted in a wide range.

In the heat pump drying process,the temperature, humidity and circulation fow of the circulating air can be accurately and effectively controlled, and the temperature regulation range is - 20 to 100 ° C (with auxiliary heating device), and relative humidity regulation range is 15%-80%, which is suitable for the drying of heat sensitive materials.

4.Time Saving.

Due to the misoperation and burning time of the existing coal-fired baking room, the temperature rises slowly, which leads to the waste of baking time. The new generation of air can protect the environment and control the temperature accurately, and the time can be set, thus greatly saving the baking time.

5.Good quality drying.

Heat pump drying is a mild drying method, close to natural drying. The evaporation speed of surface moisture is close to the internal moisture migration speed to the surface, which makes the quality, color and product grade of the dried products better. The common drying method has the advantages of less aromatic volatile matter retention, lower vitamin retention with poor heat resistance and greater color change.
