Description

Food waste disposal system

The present invention relates to a food waste treatment apparatus, and more particularly, to improve the structure of the shredding unit for shredding the food waste, thereby to shred the food waste into a smaller size, and to adjust the rotational direction of the shredding unit to break up the shredded food waste. It can be moved to the outlet side and discharges hot air generated in the process of drying food waste to the outside, but collects foreign substances and moisture contained therein so as not to be discharged to the outside to reduce environmental pollution and minimize the occurrence of odor It relates to a food waste disposal apparatus that can be.

There are various types of devices for treating food waste generated in homes or restaurants.

For example, there is a food waste grinding and drying apparatus proposed in [1].

[1] is a case in which food waste is supplied and accommodated;

A hot air supply unit connected to one end of an upper side of the case to supply high temperature hot air;

An exhaust part connected to the other end of the case and discharging high temperature moisture generated while drying the inside of the case;

A cutter part having cutter blades which are fixed to the inner bottom surface of the case and are arranged at equal intervals in number;

A plurality of arrangement is arranged along the outer circumferential surface terminating the inside of the case includes a stirring blade rotated by a drive motor.

In the technique proposed in [Document 1], when food waste is supplied to the case, the hot air supply unit heats the case to evaporate the moisture contained in the food waste, and discharges the high temperature moisture generated therefrom through the discharge portion, while stirring. The cutter blade is crushed by the food waste being rotated and stirred through the cutter.

The prior art made as described above does not smoothly crush a large or hard shell of food waste, which is between the stirring blade and the cutter blade rotating while the cutter blade is fixedly attached to the inner bottom of the case. This is because food waste must be inserted to be broken. Therefore, there was a problem that the food waste is not broken at all when the food waste is not inserted between the stirring blade and the cutter blade.

In addition, when the cutter blade is damaged or damaged, the stirring blade disposed inside the case needs to be removed from the case and then replaced. The hot air supply unit, which is connected to the upper side of the case and supplies high temperature hot air, indirectly supports the case. Since the heating method is not good thermal efficiency, there is a problem in that the energy use cost for generating hot air when used for a long time increases.

In addition, there is a problem in that environmental pollution occurs in the discharge part which discharges high temperature air to the outside together with moisture contained in the food waste while circulating inside the case, and furthermore, there is a problem of environmental pollution. There is a problem that the thermal efficiency is very low because air is not reused.
