Description

Technical Field

[0001] The utility model relates to the technical field of heat pumps, in particular to a multi-stage heat recovery air energy heat pump dryer. Background Art

[0002] Heat pump dryer is a heat-raising device, mainly used in the drying and dehydration process of food, medicinal materials, wood, agricultural and sideline products, industrial products, etc. The high-temperature heat pump drying unit uses the reverse 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 the refrigerator. Both work according to the reverse Carnot cycle principle. The difference between the two is that the former increases the temperature and the latter reduces the temperature.

[0003] However, the prior art still has the following problems:

[0004] First, most of the existing air energy heat pump dryers cannot achieve multi-stage heat recovery. Since a large amount of heat is often lost when the heat pump dryer heats the product, if the heat cannot be recycled in time, more energy will be consumed, and the energy-saving effect will be poor.

[0005] Secondly, the structure of placing products in the air energy heat pump dryer of the prior art is not convenient for installation and assembly. Because sometimes a large number of products need to be dried, if the placement structure cannot be installed, the products dried in one drying process are limited, so the drying efficiency is limited.

[0006] In view of the above problems, the inventor proposes a multi-stage heat recovery air energy heat pump dryer to solve the above problems. Utility Model Content
