Main applications for heat pump tunnel dryer / drying tunnel
The heat pump tunnel dryer is the new generation dehydration equipment. With her main characters for clean, environment friendly, energy saving, it is widely used in various industries for dehydration process. The typical field suitable for heat pump dryer are vegetables and fruits, herbs, meat, fish, seafood and etc.

Main features of heat pump dryer
Environment friendly and energy saving drying equipment. Comparing with traditional hot air drying heated by steam, this kind of dryer is with less energy consumption. No need for extra facilities in your plant for example steam boiler or fire oven.
Relatively low temperature drying without damage material surface and nutrition of the products.
Especially suitable for big and whole size material drying such as meat, fish, seafood, poultry etc.
Drying principle: Inverse Carnot cycle principle. It is like reverse air conditioning compressor working principle to increase the air temperature in dryer, also make low water content hot air circulating.
The water in the material comes out cause of air-pressure-difference. When wet air passing evaporator, the liquid refrigerant absorb the heat turn to air status. So that the wet air cool down temperature and condenser water content becoming dried air at the same time. Then dried air arrive compressor condenser unit. The refrigerant releases heat. The dried air will become high temperature status again.
It is with this circulation principle to make drying purpose.
