[0028] When the plurality of raw materials enter the dispersion cylinder 21 through the discharging hole 111 at the bottom of the feeding cylinder 12, the motor 22 drives the stirring rod 26 to rotate through the driving rod 25, and the stirring rod 26 drives a plurality of stirring blades 27 to rotate, so that the plurality of raw materials in the dispersion cylinder 21 are stirred and dispersed.
