Description

Grinding blade assembly {GRINDING BLADE ASSEMBLY}

The present invention relates to a grinding blade assembly provided to grind various grinding objects.

As the industry develops and the level of culture improves and the dietary life becomes richer, the amount of various food wastes tends to increase day by day. The amount of food waste thrown away every day nationwide is 15,075 tons, equivalent to 1,880 8-ton trucks, accounting for 31.6% of the total household waste.

These food wastes contain a large amount of moisture and are easily decayed. When buried in the soil, leachate is generated, contaminating the soil and groundwater, and when discharged into rivers, various gases and odors due to decay are generated, which can cause serious environmental problems. It is also not easy to incinerate due to a large amount of moisture.

In addition, food waste generated from homes or restaurants is not only diverse in type but also large in volume, resulting in labor loss and economic loss due to disposal, and shortening the lifespan of landfills.

Accordingly, in recent years, various attempts to utilize food waste as feed or fertilizer have been steadily progressed, but there is no appropriate treatment method due to excessively insufficient efficiency compared to treatment cost.

For this reason, in recent years, a food waste treatment apparatus configured to treat food waste generated in a home or restaurant on the spot has been developed and supplied.

Such food waste disposal apparatus is largely divided into drying type, fine granulation type, and fermentation decomposition type according to the treatment method. It is a treatment device that reduces the volume of food waste by using a method of finely pulverizing food waste.

On the other hand, since the crushing blades provided in the conventional fine granular food waste disposal apparatus are mainly provided with a single crushing blade, there is a problem in that the crushing performance and operation efficiency of food are deteriorated.
