When the cavity switches from a feeding state with the opening facing upward to a discharging state with the opening facing downward, the discharging of materials is realized.

[0004] However, during the discharging process of materials, often the materials in the same cavity are discharged together. For example, each cavity can hold 300 g of materials. When discharging, by rotating the rotating shaft by a certain angle, the discharging of 300 g of materials is realized. But when 200 g or 100 g of materials are needed, different specifications of discharging valves need to be replaced for quantitative discharging.

The first partitions and the second partitions are arranged in a staggered manner, that is, when viewed from the side view of the impeller, the first partitions and the second partitions are arranged at equal intervals on the collar.
