Finally, the material moves to the side of the circular groove 17 and is discharged outwardly through the discharging device 2, thereby achieving the effect of discharging the material and increasing the material discharging speed through the discharging device 2.

[0033] The material of the discharging device 2 is discharged outward through the grille cover 23 to achieve the discharging effect. The wind is generated by the fan 22 to absorb the material inside the equipment, thereby accelerating the discharging speed of the material, reducing material residue, and improving the discharging efficiency. The grille cover 23 plays a role in blocking the entry of external impurities. The friction mechanism 26 is driven by the fan 22 to rotate, so that the friction mechanism 26 rubs the inside of the holes of the grille cover 23, thereby avoiding the material from clogging the holes and preventing it from affecting the discharging effect of the equipment.

[0034] The drying device 3 is arranged on the outside of the mixing shell 11, and a hot air flow is generated by the dryer 31. The air flow is transported from the output pipe 33 to the inside of the mixing shell 11, so as to achieve the effect of drying the inside of the equipment, thereby reducing the moisture of the material inside the equipment, avoiding affecting the material mixing efficiency, and avoiding adhesion caused by the moisture of the material, preventing the material from agglomerating and affecting the mixing effect. By drying, the powder is reduced from adhering to the inner wall of the equipment, reducing the difficulty of subsequent cleaning. The funnel plate 34 plays the role of guiding the flow of air, and the first grid plate 35 and the second grid plate 36 play the role of blocking the powder, thereby reducing the material from entering the interior of the equipment, affecting the blockage inside the equipment, and avoiding affecting the normal operation of the equipment.
