Heat pump dryer types

Heat pump dryer is a kind of equipment that utilizes heat pump technology for drying, which has the characteristics of energy saving, environmental protection and health, etc. At present, there are a variety of different kinds of heat pump dryers on the market. The following will introduce several common types of heat pump dryer.

1. air heat pump dryer: air heat pump dryer is one of the most common types of heat pump dryer. It draws a large amount of air into the machine through the internal heat pump system, and through the process of compression and expansion, the temperature of the air rises and the heat is transferred to the materials inside the drying room to realize the purpose of drying. Air heat pump dryer is suitable for drying different materials, such as food, chemical, agricultural products and so on.

2. Circulating heat pump dryer: Circulating heat pump dryer is a kind of heat pump dryer that recycles and reutilizes the heat through the circulating system. It recovers the residual heat from the heat pump system and supplies it to the materials in the drying room again, which improves the energy utilization efficiency and saves energy cost. The circulating heat pump dryer is suitable for large quantity and long time continuous drying.

3. microwave heat pump dryer: microwave heat pump dryer is a kind of dryer combining microwave technology and heat pump technology. It utilizes microwave to heat the material, heating the material inside and outside at the same time in a short time to improve the drying efficiency. Microwave heat pump dryer is suitable for the occasions with high requirements on material quality and short drying time.

4. low-temperature heat pump dryer: low-temperature heat pump dryer is a kind of dryer which is suitable for low temperature requirement of materials. It adopts low-temperature heat pump technology to maintain the temperature in the drying room at a lower level, avoiding the secondary pollution and deterioration of materials in the drying process. Low-temperature heat pump dryer is suitable for industries that are sensitive to the temperature of materials, such as pharmaceuticals, health care products and so on.

5. Film heat pump dryer: Film heat pump dryer is a kind of heat pump dryer that utilizes film technology for drying. It uses the film to contact with the material, and through the adsorption and evaporation process of the film to evaporate the water in the material and realize drying. Thin film heat pump dryer is suitable for industries with high requirements on materials, such as chemical industry, food, etc..

These are several common types of heat pump dryer, each type has its applicable occasions and characteristics. When choosing a heat pump dryer, you should choose according to your own needs and material characteristics in order to get drying effect.
