In this garbage processing apparatus, bacteria such as bacteria inhabit the garbage processing material, and the garbage is decomposed by these activities. By the way, in the above-mentioned garbage processing apparatus, since the decomposed garbage generates a decomposed odor, there is a problem that an excessive amount of garbage is input or a bad odor is generated when garbage having a strong odor is input. there were.

In some cases, a deodorizing device for heating and deodorizing with a catalyst or the like is provided in an exhaust duct to deodorize exhaust odor.
There are problems that the deodorizing device is very costly, and that the running cost such as electricity cost and replacement of the deodorizing material is high. Furthermore, it is necessary to reduce the exhaust air volume in order to enhance the deodorizing performance, and it is not possible to obtain sufficient water removal capacity at the time of deodorizing, the water content of the garbage processing material increases, the decomposition performance is reduced, and There were problems such as occurrence.

[0004] The present invention has been made in view of the above description, and when exhausting the odor generated during the decomposition of garbage, mixes it with the outside air, dilutes it, and exhausts it. An object of the present invention is to provide a garbage disposal apparatus that can reduce the concentration of exhaust odor without increasing the cost.

[0005]

In order to solve the above-mentioned problems, a garbage disposal apparatus according to the present invention is arranged to put garbage into a garbage disposal tank 1 filled with a garbage disposal material and decompose garbage.
