working principle:
Fuel coal burns after entering the furnace to generate heat. After combustion, the flue gas is input into the heat exchanger for multiple cycles and then discharged, and the cold air is output after being heated by the outer wall of the heat exchanger, which improves thermal efficiency, saves energy consumption, and effectively reduces costs.
performance:
High degree of automation: fast heating, high utilization rate of heat energy, automatic temperature control, and guaranteed grain quality.

● Adopt thin-layer drying design, the grain is heated evenly;
● The whole machine is connected by bolts and has multiple observation ports, which is convenient for maintenance and replacement;
● Control cabinet analog centralized display, real-time monitoring of moisture, easier and more intelligent operation; 
● Grain discharge wheel is controlled by stepless speed change, which ensures the uniformity of material drying range; 
● The whole machine adopts building block structure, which is easy to operate and maintain; 
● Various forms of heat sources can be used as required.
