The controller can alternately control the first blowing assembly 61 and the second blowing assembly 62 to draw air from the material chamber 3 and blow air into the material chamber 3, and the first blowing assembly 61 blows air into the material chamber 3. The blowing of the blowing and the blowing of the second blowing and suction assembly 62 into the material chamber 3 are carried out alternately.
