The spiral blade 11 is spirally connected to the vertical rod 10 to form an integrated structure. Starting the servo motor 5 can drive the vertical rod 10 and the spiral blade 11 to rotate, thereby stirring and mixing granulation. A circular tube 12 is fixedly arranged on the inner wall of the tank body 1 near the spiral blade 11. The other end of the connecting pipe 4 passes through the cover plate 2 and is connected to the circular tube 12. The circular tube 12 is made of stainless steel and is tubular.
