The present invention relates to a food waste disposer, and more particularly, to a household food waste disposer for processing food waste discharged from the home to reduce waste.

In general, a disposer is used as an example of a device that grinds food waste or fish bones in a kitchen and sends them to the sewer. Such a conventional disposer is usually installed under the drain of a sink. The disposer is composed of a motor unit and a crushing unit, and the food waste is crushed by a rotary blade and a fixed blade which are rotated by the motor. And the food dregs bounced off by the rotary blades hit the fixed blades strongly and smash into the sewers by crushed and crushed water. The disposer for treating such household food waste has a problem that can cause environmental pollution because the entire amount of the crushed household food waste is discharged to the sewer.

Therefore, the present invention has been proposed to solve the above problems, and an object of the present invention is to provide a food waste disposal apparatus that can reduce the environmental pollution by reducing the amount of household food waste discharged.

In addition, the present invention is to provide a food waste processor that can reduce the odor generated when processing food waste at home to maintain a comfortable indoor environment.
