A motor 20 is fixedly installed on the left side of the drying box 1, and the output end of the motor 20 is fixedly connected to the left side of the first rotating rod 4. By setting a stirring mechanism, the raw materials are added to the inner cavity of the drying box 1 through the feed port 2, and the motor 20 and the heater 3 are started to drive the first rotating rod 4 and the stirring blade 5 to rotate. At the same time, through the cooperation of the connecting frame 6, the second rotating rod 7 and the stirring blade 8 are driven to rotate with the first rotating rod 4 as the center. When the second rotating rod 7 moves, the gear 17 and the gear ring 16 are meshed and connected, so that the gear 17 drives the second rotating rod 7 to rotate, and the rotation direction of the stirring blade 8 is opposite to that of the stirring blade 5, thereby improving the stirring effect. The shape and size of the rotating ring 12 are consistent with the connecting groove 11, and the connecting groove 11 is blocked to prevent the raw materials from falling into the inside of the connecting groove 11 and affecting the normal operation of the equipment.

When the first rotating rod 4 rotates, the third rotating rod 9 is driven to rotate at the same time through the cooperation of the transmission belt 19. Since a plurality of crushing rods 10 are installed on the surface of the third rotating rod 9, the crushing rods 10 are made to rotate at the same time. The continuous rotation of the crushing rods 10 can prevent the raw materials from being blocked at the feed port 2. At the same time, through the cooperation of the connecting frame 6, the second rotating rod 7 and the stirring blade 8 are driven to rotate with the first rotating rod 4 as the center. When the second rotating rod 7 moves, the gear 17 and the gear ring 16 are meshed and connected, so that the gear 17 drives the second rotating rod 7 to rotate, and the rotation direction of the stirring blade 8 is opposite to the rotation direction of the stirring blade 5, thereby improving the stirring effect.
