The present invention relates to a food waste processing apparatus, and relates to a food waste processing apparatus using microwaves that are pulverized and dried by using microwaves.

Due to the difficulty of disposing of food waste, food waste emission standards are being strengthened gradually.

The biggest problem with food waste is that it contains a lot of moisture, which easily rots and generates odors and sewage.

Simply embedding food waste underground causes environmental pollution and is not suitable for long-term treatment due to limited land area.

And food waste can be used as livestock feed when processed to remove foreign matter, or it is of high value as a compost.

In order to effectively treat food waste, water must be removed and there are a number of conventional technologies developed for this purpose. Hereinafter, a representative prior art will be described.

First, a technology related to the treatment method of household food waste of the Republic of Korea Patent Application No. 1997-0013624 has been known, this technology is finely pulverized food waste generated in the home in the grinding chamber (2) injection hopper (3) Injected into the processing chamber (4) through the transport conveyor (5) in the processing chamber 4 in the process of microwave microwave generated from the microwave generator 7 is irradiated to food waste and dried in a dielectric heating method The present invention relates to a method for treating household food waste in which steam is discharged to an exhaust system and sterilized food waste is recycled.
