Since the pitch and diameter of the quantitative auger 23 are fixed, the amount of material conveyed per revolution is also fixed. Therefore, by controlling the rotation speed and rotation time of the rotary motor 25, the conveying amount of the material can be accurately controlled, and the feeding accuracy of the feeding valve is further improved.
