Description

Food leftover processing apparatus {Apparatus for treating leftover food}

The present invention relates to an apparatus for processing food residues, and more particularly, a water washing process that is installed in a place where group meals such as schools, public institutions, units, and service areas are provided, and removes salt and oil through washing the food residues generated; , It relates to a food residue processing apparatus for fermenting the food residues after the washing process and sequentially performing the fermentation processing process to microbially decompose and discharge the food residues.

Recently, garbage is a serious issue, and among them, the problem of processing food waste generated in each household or restaurant is the most serious.

Currently, the amount of food waste generated in Korea amounts to dozens or more based on 8-ton trucks, and the cost to dispose of it is nearly 10 trillion won.

Therefore, although the nation is actively promoting the separate collection of food waste and the removal of water, the amount of food waste has not been significantly reduced.

In addition, if we look briefly at the method of actually handling food waste, food waste generated at home emits a smell and decays if left for a long time without being removed or disposed of immediately, impairing the sanitary environment and causing a sense of filth, while leachate during collection and transportation It is an object that has been generated or has difficulties in its disposal, such as refusing to be brought into a landfill.

On the other hand, in addition to achieving the goals of dehydration and weight loss, the food waste processor maximizes the treatment effect, minimizes hygienic problems such as decay and odor, minimizes energy consumption, minimizes sewage and air pollution, minimizes noise and vibration, and causes breakdowns All requirements such as minimization of waste, appropriate processing capacity and processing time, securing safety, convenience of cleaning and use, recycling of processed materials, low manufacturing cost, and minimization of installation space must all be satisfied.

In terms of treatment methods, the prior art in this field is a combination of several methods such as fermentation, extinction, screw compression dehydration, piston compression dehydration, dehydration drum rotation centrifugal dehydration, heat drying, incineration, and the like. There are ways.

The rotary dehydration type food processor is large in size, and after dehydration, dirty food waste must be withdrawn from the main body again, and the dehydration rate is also low. When it is introduced, it is difficult to remove it.
