And it is preferable that the inlet 120 is further provided with a food waste prevention part 122 as shown in FIG. 1. The food waste prevention part 122 is installed at the entrance of the food inlet 120, but has a considerable elasticity, so when the food waste is inserted, it is opened while sagging downward by the weight of the food waste, and the food waste is not inserted. In this case, it is kept closed by the elastic force. The food waste prevention part 122 prevents the food waste crushed material that bounces upward during the crushing process of the first crushing part 130 from being discharged to the outside.

Meanwhile, in this embodiment, the food waste inlet 120 is preferably formed on the rear side of the upper surface of the treatment bin 110, as shown in FIG. 1, as it is suitable for carrying and inputting food waste.

Next, the primary crushing unit 130 is installed under the food waste inlet 120, as shown in FIG. 1, for primary shredding the food waste that is input through the food waste inlet 120. It is a component. Since the food waste input through the food waste inlet 120 has various sizes and shapes, it is very difficult to treat it in this state. Accordingly, the first crushing unit 130 facilitates treatment by first crushing the food waste into a predetermined size in the course of free fall by its own weight, which is input through the food waste inlet 120.

To this end, the first crushing part 130 may be specifically composed of a rotating rod 132 and a cutting blade 134 as shown in FIG. 1.
