When the first stirring mechanism 8 stirs the raw materials, the rotating rod 16 is engaged with the gear ring 18 to drive the rotating shaft 22 to rotate, so that the rotating blade 23 performs vertical stirring of the raw materials. The first lifting member 25 will be driven to rotate, and the cooperation between the first lifting member 25 and the second lifting member 26 will make the first lifting member 25 drive the second lifting member 26 to reciprocate up and down when rotating. At this time, when the second lifting member 26 moves downward, the push rod 30 will move downward synchronously with the second lifting member 26, and the push rod 30 will squeeze one side of the top of the swing plate 29 when moving downward, so that one side of the top of the swing plate 29 will deflect downward, and the other side of the top of the swing plate 29 will drive the top plate 31 to deflect upward. When the lifting member 26 moves upward, at this time, the other side of the top of the swing plate 29 will drive the top plate 31 to deflect downward, and this cycle repeats over and over again.
