Description

Food sorting bin washing device {Washing device for food sorting bin}

The present disclosure relates to an apparatus for washing a separate food collection box, and more particularly, to an apparatus for washing the inside and outside of the food collection box.

Food collection boxes are often used in restaurants or apartment complexes. The food collection bin collects discarded food and hands it over to a specialized disposal company that either reuses it or disposes of it.

Such a food collection box is a very important item that can prevent environmental contamination by food, but it is an item to be avoided because decayed food residues exist on the outer surface as well as the inside of the food collection box.

Most of the food collection boxes are repeatedly used in a contaminated state, and cleaning nozzles are sometimes washed by primitive methods. According to this, contaminated washing water discharged from the collection box may contaminate the surroundings during washing. Therefore, it is necessary to find a method capable of effectively collecting contaminated water generated during washing of the collection box.

Contaminated food collection boxes are cleaned by specialized cleaning devices, and these cleaning devices have a very complex structure and are expensive to manufacture. In addition, since they use high-pressure washing water, a large amount of washing water is required during washing, and it is very difficult to treat a large amount of washing contaminated water according to the washing water used.
