Heat pump drying equipment

Heat pump drying equipment is currently a relatively mature new drying equipment and also the development trend of the drying industry. In some food and pharmaceutical processing industries, there is a high demand for drying. At present, there are still many drying equipment that use fossil fuels such as coal to heat air for drying. Therefore, during the drying process, some dust and odors are inevitably generated, which pollute the dried products and are not conducive to environmental protection. The heat pump drying equipment we produce achieves closed circulation of dry air, ensuring product quality while also saving energy and reducing emissions. This device does not require a heating medium, as long as the heat source is converted and water vapor is discharged, it can dry various products, which is convenient for our use.

What is the working principle of heat pump drying equipment?

During the operation of this device, it mainly uses the pressure of the compressor and the conversion of high-temperature gas to condense the steam generated during the drying process and discharge it outdoors. Steam evaporation is common in the drying process, and if the evaporated water is not discharged outside in a timely manner, the purpose of product drying cannot be achieved. In addition, it will increase drying time, causing waste and resource loss. In the design principle of this device, steam can be directly treated with hot air and then quickly discharged through a dehydration system to achieve the purpose of drying the product. Secondly, add the refrigerant throttle valve to the heat pump drying equipment. This throttle valve can absorb the water vapor discharged into the compressor for further reciprocating, which can maintain the temperature inside the drying chamber and also play a role in reuse.
