Corresponding rigid support members are fixed between two adjacent stirring rods, and the length of the rigid support member is greater than the length of the elastic part of the stirring rod. During the stirring process, that is, during the rotation of the stirring shaft, the rigid part of the stirring rod contacts the material pile and stirs the material.
