Description

Apparatus for disposing food waste

The present invention relates to a food treating apparatus, and more particularly, to a food treating apparatus capable of efficiently reducing and treating volume and weight of food waste and the like.

In general, food waste discharged from homes and restaurants is separated from other recyclable waste, and food waste emitted from homes and restaurants has a high water content, and the odor is discharged during the storage process before transporting to a landfill. Of course, this may cause pests to occur around. Due to this problem, the food waste is a situation that causes a number of hygiene problems, such as kitchen is stored in the bag.

Therefore, various kinds of apparatuses for effectively treating such food waste have been developed. One of them is an apparatus for drying and reducing food, and a food treatment apparatus is usually used in which food waste is pulverized and then placed in a treatment tank and heated by heating.

However, food waste mixed with rice or broth due to the Korean food culture becomes agglutinated when it is heated and dried in a treatment tank. The contaminated food waste is not stirred well, so the food waste in the lower layer is not substantially dried, which may cause pests when left for a long time.

Moreover, the apparatus for drying food waste in such a state has a problem that excessive electric charges are generated due to excessive time for drying.

Therefore, these problems must be solved for the recycling of food waste through the separate collection, the cleanliness and hygiene of the kitchen.

In order to solve the above problems, it is an object of the present invention to provide a food processing apparatus that can efficiently process by reducing the volume and weight of food waste and the like.
