With the continuous development of production technology, the development of temperature circulating dryer has put forward new requirements for the heat source of dryer, that is, cost saving, energy saving, easy operation, safety and reliability. In this paper, the heat source of low temperature circulating dryer is introduced briefly. (1) Using fuel as heat source. Most of the basic heat sources used in the design of cryogenic circulating dryers are fuel. Because fuel is a relatively popular energy source, kerosene was the main source at first, and then high-clean diesel was mostly used according to the national conditions. Using fuel as raw material, the fuel is sprayed into a fog through the burner nozzle to heat the red ignition rod and ignite the fuel to provide heat for the dryer.
