As described above, according to the commercial garbage processing apparatus of the present invention, the garbage put into the hopper of the primary crusher is roughly crushed by the primary crusher.
The coarsely crushed garbage is transferred to a secondary crusher by a conveyor and finely crushed, and the finely crushed garbage is transferred to a dehydrator by a conveyor and dewatered, and the dewatered fine crushed. The garbage is transferred to the garbage disposer and disintegrated, but the finely crushed garbage introduced into the garbage disposer is finely crushed, including hard bones such as fish, cows, pigs, and birds. Being agitated together with the culture bed material containing microorganisms, the finely crushed garbage has a good contact efficiency with the culture bed material, so that the garbage can be efficiently eliminated and eliminated, and the treatment amount is increased. Since the efficiency can be improved, it is extremely excellent as a commercial garbage processing apparatus that needs to process a large amount of garbage. In addition, in the commercial garbage disposal apparatus of the present invention, since all operations from the input of the garbage to the garbage disposal machine are performed in a sealed state, the odor of the garbage does not leak to the outside, so that the accident can be avoided. Work can be done safely without fear. Furthermore, the commercial garbage processing apparatus of the present invention
Except for the garbage disposer, the primary crusher, secondary crusher, dehydrator and each conveyor can all be washed with washing water to keep them clean, and the sewage after the washing and the sewage dehydrated by the dehydrator. Is completely detoxified and drained, so there is no risk of pollution caused by sewage.
