Thereafter, the linear member 41 is moved downward and the wing portion 422 is spaced apart from the external force acting portion 48 and the angle (a) can recover the initial angle, and in this state, the wing portion 422 is downward moved, and the process described above can be repeated.

For reference, the linear member can be moved downward to a point where the wing portion 422 is less than 1/3 of the height of the hopper 1, and can be moved upward to a point where it becomes more than 3/2 of the height of the hopper 1 In addition, the external force acting part 48 may have a protrusion amount in consideration of this.

In addition, a plurality of holes having a diameter larger than the diameter of one particle of the contents and smaller than the sum of the diameters of two particles of the contents may be formed in the wing portion 422 . Here, the diameter of one particle of the content may mean the smallest diameter among the diameters of the particles of the content considering the error range. Due to this hole, at least some of the particles located on the wing part 422 when the wing part 422 moves upward may fall to the lower side of the wing part 422 through the hole and be better mixed, Resistance by the contents acting on the wing portion 422 when moving downward may be reduced.

Also, the minimum distance between the plurality of holes may be greater than the diameter of the holes. Accordingly, when the wing portion 422 moves upward, at least a portion of the contents of the particles positioned on the wing portion 422 fall to the lower side of the wing portion 422 through the hole, and at least some do not pass through the hole and the wing portion 422 . ), mixing of the contents can be efficient, and when the wing part 422 moves downward, the resistance by the contents passing through the hole of the wing part 422 and acting on the wing part 422 can be reduced. have.

In addition, at least a portion of the hopper (1) may be made of a temperature control member (13) for absorbing heat inside the hopper (1). For example, a side portion of the hopper 1 may be formed of a temperature control member 13 .

Referring to FIG. 5 , the temperature control member 13 includes the inner plate portion 12 , the inner plate portion 13 overlapping the inner plate portion 132 , and at least a portion of the inner plate portion 12 and the inner plate portion. It is provided between at least a portion of (13) may include a Peltier element 11 for absorbing heat from the inner side and dissipating heat from the outer side according to the Peltier effect.

The Peltier element 11 is an element using the phenomenon that when a type of conductor is combined according to the Peltier effect and current flows, one contact point heats up and the temperature rises, and the other contact point absorbs heat and lowers the temperature. .

Accordingly, when power is supplied to the Peltier element 11, it can absorb heat from the inner side and dissipate heat from the outer side, and the inner plate part 12 is provided on the inner side of the Peltier element 11 to provide the Peltier element 11. It is possible to protect and easily transfer the heat absorption of the Peltier element 11 (guide the movement of heat (heat absorption) by the Peltier element 11). In addition, the inner plate portion 13 is provided on the outer portion of the Peltier element 11 to protect the Peltier element 11 and can easily transmit the heat of the Peltier element 11 . Therefore, the inner plate portion 12 and the inner plate portion 13 are made of a ceramic material is widely used, but if it is a material that can easily transmit the heat or cold air emitted from the Peltier element 11, it is composed of various materials. can be

Accordingly, the inner plate portion 12 may be heat absorbed by the Peltier element 11 , and the inner plate portion 13 may generate heat by the Peltier element 11 . In addition, the temperature control member 13 may be provided such that the inner plate part 12 faces the inside of the hopper 1 , and the inner plate part 13 faces the outside of the hopper 1 .
