[0027] The hot air mechanism 3 includes an inner cylinder 3.1 located inside the cylindrical outer shell 2.1 and fixed at its rear end to the front wall of the rear end plate 2.2; a cover 3.2 fixed at its top end to the inner circumferential wall of the inner cylinder 3.1 and corresponding to the area of ​​the outer micropores 2.1.3; a bottom shell 3.4 connected to the bottom end of the cover 3.2; and multiple electric heating tubes 3.7 disposed within the bottom shell 3.4. The area of ​​the inner cylinder 3.1 corresponding to the outer micropores 2.1.3 is filled with inner micropores 3.1.1. A fan-shaped plate 3.3 is fixed between the top ends of the inner circumferential wall of the inner cylinder 3.1 and the cover 3.2. A funnel-shaped shell 3.5 is connected to the bottom end of the bottom shell 3.4, and the bottom end of the funnel-shaped shell 3.5 is connected to the front end of the air inlet bend 3.6. The rear end of the air inlet bend 3.6 is fitted into the perforation 2.2.2. The inner cavity of the bottom shell 3.4 is provided with multiple sets of electric heating tubes 3.7 along the vertical direction. The electric heating tubes 3.7 in each set are evenly distributed along the horizontal direction, and the electric heating tubes 3.7 in two adjacent sets are staggered left and right.

[0028] The rotary material transfer mechanism 4 includes a disc 4.1 that is rotatably fitted onto the front end of the inner cavity of the cylindrical outer shell 2.1, and a plurality of radial strips 4.2 whose front ends are fixed to the outer edge of the rear wall of the disc 4.1 and extend into the cavity between the cylindrical outer shell 2.1 and the inner cylinder 3.1.
