The present invention relates to a waste vinyl sorting device for food waste, and more particularly, to a device for easily sorting waste vinyl and residual food waste selected from food waste through a sorting process of a food waste treatment system. The present invention relates to a waste vinyl sorting device for food waste, which can obtain a more efficient sorting efficiency by forming a floating atmosphere in which waste vinyl can be separated and sorted by the flow of air in a space.

Generally, there is a method of treating food waste generated at home or a restaurant, etc., by embedding food waste in landfill and treating the selected food waste by a food processing system for a certain period of time and recycling it as compost. .

In the above method, the landfill treatment of food waste not only secures landfill sites, but also requires excessive costs such as transportation and landfill operations, and in recent years, composting food wastes has caused problems of extreme environmental pollution due to odors and leachate after landfilling. The recycling method is mainly used. This compost treatment method has the advantage of minimizing the occurrence of environmental pollution and of generating additional benefits from recycling.

The general process of the food waste treatment system for producing compost by using the food waste described above is as follows.

First, the food waste collected through the crushing process is crushed to a predetermined size, and the foreign matter contained in the finely crushed food waste is sorted in the sorting process. It is to produce compost by fermenting the food waste from which water and salt are removed through the fermentation process.

In the above, the sorting process is one of the important processes in which the compost quality is determined according to the sorting efficiency of the foreign matter, and the amount of the foreign matter contained in the food waste using the sorting device, in particular, is rapidly generated due to the popularization of instant food. It is to sort out this increasing packaging waste vinyl.

The sorting apparatus used in the sorting process has a structure in which a cylindrical drum screen having a plurality of discharge holes having a predetermined diameter penetrated on the outer circumferential surface thereof can be rotated in one direction. While passing through the screen, only pure food waste is discharged to the discharge holes to separate and sort waste vinyl contained in the food waste.

However, among the foreign foods caught through the sorting device, residual food residues such as bone fragments, fruit slices, vegetable slices, instant foods, etc., which are not crushed in a proper state in addition to the waste vinyl, are filtered together. Pure food waste and sorted waste are discharged with vinyl in a ratio of approximately 80 to 20.

The waste vinyl and the remaining food waste thus filtered are landfilled or incinerated after collection, and the residual food residues are relatively increased in volume, which leads to excessive costs for landfilling or incineration. There is a problem that causes environmental pollution by landfill and incineration.

Accordingly, there is a patent registration No. 10-0420495, filed and filed by the applicant of the present application on May 15, 2001, as a waste vinyl sorting device for removing residual food waste contained in waste vinyl sorted in the sorting process. .
