[0006] Furthermore, the heating element has an internal protective layer, which is made of titanium alloy.

The heating body 7 is provided with a material inlet 14, a material outlet 13 and a temperature sensor 16. The material inlet 14 is located at the bottom of the outer wall of the heating body 7, and the material can be put into the heating body 7 through the material inlet 14.

The electromagnetic coil winding 9 and the temperature sensor 16 can be connected to the heater. The motor is started, and the motor speed is set to 120 rpm. The magnetic coupler 3 rotates accordingly, causing the bottom main shaft 12 to rotate simultaneously. The spiral scraper 8 fixed on the main shaft 5 also rotates simultaneously. Material can be added through the material inlet 14 at a flow rate of 12 m³ / h. The spiral scraper 8 ensures the material is fully heated within the heating element 7 before being discharged from the material outlet 13.
