Can be formed. That is, the guide part 1711a may be shaped to protrude outward from the upper end of the input part 1711. Therefore, when the raw material is added, the input raw material may be moved toward the input unit 1711 along the inclined inner surface of the guide unit 1711a without falling vertically into the input unit 1711 of the hopper 171. Through this, a large amount of the raw material is sequentially moved along the inner surface of the guide portion 1711a toward the input portion 1711 side, so that a large amount of the raw material is instantaneously dropped vertically and extends to the lower side of the input portion 1711.

For example, the inflow prevention member 1755 is a plate-shaped member protruding outward from the rotation shaft 1751, and an inclined surface 1755a may be formed on the upper side thereof.

Therefore, the raw material does not primarily fall along the inclined inner surface of the guide portion 1711a and fall vertically, stably flows into the input portion 1711, and secondly, evenly through the rotation of the mixing portion 1753. The mixture may be finally (third) introduced into the discharge unit 1713 indirectly through the inclined surface 1755a of the overflow prevention member 1755, thereby being stably transmitted to the body 13.

Next, the transfer unit 177 is disposed outside the discharge unit 1713 in a state coupled to the control unit 173 so that the raw material discharged to the discharge unit 1713 is introduced into the induction pipe 1177, and the guide tube It may include a transfer device (1773) installed inside the (1771) to transfer the raw material introduced into the guide pipe (1771) to the body portion (13).

For example, the conveying device 1773 installed inside the induction pipe 1771 may be a conveyor type device for conveying an object. That is, the conveying apparatus 1773 may be a screw conveyor apparatus having a structure similar to the conveying screw 175 or a belt conveyor apparatus for conveying an object by rotating the belt. However, the transfer device 1773 is not limited to this, and may be replaced with a configuration that performs the same function as necessary for use.

Finally, the controller 173 may control the driving of the transfer screw 175 and the transfer device 1773 installed inside the transfer unit 177.

For example, the control unit 173 includes a control module (not shown) therein to control the power unit 179 coupled to the rotary shaft 1751 and the transfer unit 1773 of the transfer screw 175, respectively. can do. Accordingly, the user may change the supply conditions of the raw material by controlling the operating time or rotational speed of the feed screw 175 and the transfer device 1773 according to the raw material of the raw material through the control unit 173.
