1. The upper cover, barrel body and cone are all made of stainless steel.

2. Isolated high temperature resistant fan, the air inlet of the fan can withstand higher operating temperature.

3. The hot air duct adopts the design of downward blowing without isolation net to ensure that the raw materials are first in first out and the dust accumulation in the interior of the isolation net does not need to be removed.

4. The electric heating pipe adopts the double casing method. The air is preheated first and then enters the electric heating pipe, which reduces the consumption of electric heating and saves energy.
