The difference between dry and hot air drying of grain drying equipment is different from the traditional hot air drying, which is different from the way of air circulation. Heat pump drying time and space in the drying chamber and heat pump dryer closed cycle.

It uses heat pump dryer refrigeration system to cool off from the drying chamber of the wet air, when the wet air flows through the heat pump evaporator, the internal heat of the low pressure refrigerant to absorb the heat from the liquid into a gas, air cooling and discharge of most of the condensed water.

From the evaporator refrigeration compressor by low-pressure steam condenser to boost evacuation. When to take off the wet cold air flows through the condenser, the high-pressure refrigerant due to condensation and heat release, outside air is the hot air heating returned to the drying chamber to dry to dry products. From the condenser out of the high pressure refrigerant flow through the expansion valve to continue the next cycle of the evaporator.

If you want to know for working principle of grain drying equipment knowledge, welcome to inquiry and order.
