At the same time, the drive motor 14 is activated to drive multiple sets of stirring rods 16 to rotate through the rotating shaft 17. While the stirring rods 16 are rotating, they can stir the raw materials inside the heating tank 8 to improve the heating uniformity and realize the preheating of the raw materials.

[0029] A cylinder 13 is fixedly connected to the top of the fixed cylinder 12, a wedge-shaped blocking plate 18 is fixedly connected to the bottom of the rotating shaft 17, a feeding port 15 is fixedly connected to the left side of the top of the heating tank 8, and a guide pipe 7 is fixedly connected to the bottom of the heating tank 8.

The electric heaters 9 on both sides of the heating tank 8 are activated, and heat is conducted into the tank through the heat-conducting layer 10, thereby heating the raw material inside the heating tank 8. At the same time, the drive motor 14 is activated, which drives multiple sets of stirring rods 16 to rotate through the rotating shaft 17. The rotation of the stirring rods 16 can stir the raw material inside the heating tank 8 to improve the heating uniformity. After the raw material has been heated inside the heating tank 8, the cylinder 13 is activated to lift the mounting box 11.
