What are the advantages of a heat pump dryer in drying medicinal herbs?

A heat pump is essentially a heat boosting device. The high-temperature heat pump drying unit uses the inverse Carnot principle to absorb heat from the surrounding environment and transfer it to the heated object (object with higher temperature). Its working principle is opposite to that of a refrigeration unit, both of which work according to the inverse Carnot cycle principle. The former increases the temperature while the latter decreases the temperature.

With the development and application upgrade of heat pump dryers in food and medicinal material drying, the new technology adopted by air dryer manufacturers has more obvious advantages compared to traditional vegetable drying and coal-fired drying. This is also the reason why heat pump dryers are favored in the current and future markets.

Firstly, the application research scope of food as a heat pump dryer is more extensive. Through effective control and the development status of heat pump operation, the temperature influence inside the dryer system can be controlled between 20-80 ℃, which cannot meet the majority of material drying functional requirements of enterprises. The air dryer manufacturer reminds that the range of heat pump drying includes: vegetables, seafood, traditional Chinese medicine, food, crops, industry, meat products, fruits, flowers, fruits and vegetables, fish, meat and poultry, and other agricultural, forestry, animal husbandry, sideline and fishery products. Industrial and living products such as printing, textiles, electroplating, ceramics, rubber, etc. can all be directly applied to heat pump drying technology.

Secondly, food heat pump dryers can easily achieve environmental protection and pollution-free performance. The drying process only requires placing the materials into the dryer, which can be achieved in a completely enclosed space. During the drying process, vegetables are not affected by external dust, impurities, and odors in the air, so they will not cause secondary pollution to the dried materials, especially to some edible materials.

Thirdly, save labor costs. The heat pump dryer is an intelligent one click operation. When the power supply is set to the operating curve of the equipment, there is no manual watch, and the material can only wait for the drying process to complete.

Fourthly, the food heat pump dryer adopts a more scientific and reasonable air duct design to ensure that the temperature and air volume of each part of the dryer are basically consistent, thereby ensuring the uniformity of material drying.

Fifth, there are no safety hazards. Air energy heat pump drying technology, equipment temperature and humidity intelligent control, temperature will not be too high, no safety hazards such as open flames.
