Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food waste disposal system capable of separating and removing foreign matter,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a food waste disposal system, and more particularly, to a food waste disposal system capable of separately separating and removing substances other than food waste from foods and separating foreign substances during food waste disposal.

Generally, food wastes generated from homes and restaurants contain a large amount of water and contain a large amount of water. Therefore, not only is it easily decayed when the temperature is high, but most of these food wastes are composed of organic materials. Leachate, along with odor, can cause serious environmental problems that pollute the soil and groundwater.

Such food wastes not only cause waste of resources but also cause soil pollution and water pollution due to environmental pollution caused by disposal treatment, that is, leachate generated from food waste, and due to odor and pests caused by food corruption, And causing infectious diseases.

As a method for treating such food waste, various treatment methods such as compression dewatering, freezing, and heater drying have been developed and used.

Here, the pressurized dewatering system can minimize the volume by squeezing the food waste, but the moisture generated by squeezing the food waste must be collected separately. If you leave the collected water at this time, it will become rotten and smell.

Frozen food can freeze food waste to prevent decay and odor, but the volume of food waste can not be reduced. And the frozen food garbage is melted in the process of transportation and storage, and moisture may be formed and odor may be generated.

The heater drying method directly applies heat to the food garbage so that the food garbage is dried. At this time, since the heater directly heats the food waste, the food waste burns and another odor may be generated, and there is a risk of fire, and if the heater is not evenly distributed to the food waste,

In addition, when disposing food garbage, it is often the case that the garbage bag is disposed of as garbage bags or the garbage that is not classified as food garbage is put in the garbage, so that the people collecting the garbage have to separate the garbage bag from the garbage do.

Therefore, there is a need for a food waste disposal system capable of selectively separating foreign matter such as envelopes from food waste, and minimizing the odor of food waste.
