Brief Introduction of Drying Working Principle of Air Energy Drying Equipment

Air drying equipment is a very commonly used automatic drying equipment. Because the air energy drying equipment has the advantages of high drying efficiency, good drying quality, stable quality, environmental protection and energy saving, and low investment cost, the equipment has been widely used in food processing, traditional Chinese medicine processing and other fields. Fang Xin Machinery will briefly introduce the composition and drying principle of air energy drying equipment.

First of all, let's introduce the equipment structure of the drying room. The air energy drying equipment is mainly composed of auxiliary accessories such as drying room, heat pump host, electric control system, circulating air system, stainless steel tray rack, waste heat recovery dehumidification device, electric control system, etc. Drying chamber generally used10CM polyurethane insulation board is mainly used for heat preservation, avoid heat loss, increase the temperature of the drying room, and improve the efficiency of material drying; the air energy heat pump host mainly uses the reverse Carnot principle to absorb heat from the air, provide a heat source for the drying host, and transfer it to The material is dried; the function of the circulating air system is mainly to use pure hot air to bring heat to all corners of the drying room to increase the temperature of the drying room, and take away the evaporated moisture in the material; the waste heat recovery dehumidification device dehumidifies the high humidity water in the drying room through the condenser to ensure the air drying in the drying room and the drying efficiency of the material. The waste heat recovery device heats the waste heat recovery and re-enters the circulating air system through the fan to improve the efficiency of heat energy utilization and achieve the effect of energy saving and environmental protection; the temperature control system of the electronic control system is mainly used to automatically adjust the temperature, humidity and drying time according to the drying parameters set by the customer and the appropriate drying process curve to ensure the drying quality of the material.

The working principle of the heat pump drying chamber is mainly to use the refrigerant to become high-temperature and high-pressure gas through the compressor, and then enter the condenser to dissipate heat. The heat released by the condenser is sent to the drying chamber by the circulating fan to heat the air in the drying chamber. As the temperature in the drying chamber increases, the moisture of the drying material will gradually evaporate, and then the moisture will be discharged through the moisture discharge system. Then, the steam discharged from the humidity removal system will be recirculated and heated after the condenser is dehumidified, and will enter the circulating air system again through the fan, and so on until the material is dry. Compared with the traditional air drying and combustion drying, the air energy drying equipment can not only control the drying temperature, humidity, time and other parameters of the material more accurately, ensure the drying quality of the material, but also improve the utilization rate of the heat energy of the equipment, so that the equipment has the characteristics of high utilization rate of heat energy, low energy consumption and low operating cost, no emission of gas pollutants in the drying process, no special supervision is needed, and time and energy are saved to reduce labor cost, and save all kinds of unnecessary expenses. Therefore, air drying equipment has become one of the commonly used drying equipment in the drying industry.
