In this process, the oxygen saturation in the agitator 15 is increased by the introduction of gas from the outside, and the fermentation efficiency can be maintained or increased.

The food garbage disposal apparatus according to the present invention is characterized in that the food garbage introduced into the stirrer 15 is treated by microbial fermentation and water contained in the food garbage is converted into steam in the fermentation process. The food garbage disposal apparatus circulates the gas generated around the stirrer 15 to prevent the gas from being discharged to the outside, thereby preventing the odor from being discharged to the outside. The food garbage disposal apparatus according to the present invention can be installed in various places and is applicable to industrial use, assembly building, commercial use, and is not limited by application field or structure.

The overall operation of the processing apparatus can be controlled by the control unit 11 and the control unit 11 can control the processing of the processing apparatus based on the detection information measured by the temperature, humidity or weight detection unit . Food waste can be introduced into the agitator 15 through the inlet D and the agitator 15 can be in the form of a drum or a cylinder. The fermentation mode can be set according to the kind of the food waste, and microorganisms for fermentation can be put into the stirrer 15 through a separate route as needed. The fermentation setting unit 12 may have a function of determining fermentation conditions based on information such as the information detected by the weight detection unit 131 and the water content of the food waste. The fermentation setting unit 12 sets the fermentation setting unit 12 such as a fermentation temperature, a rotation speed of the stirrer 15, a temperature set in the temperature control unit 17, or a temperature of the air introduced through the air inflow unit 18, May be determined. The fermentation setting unit 12 may have input means, and fermentation conditions may be determined through the input means. Or the fermentation setting unit 12 can set the fermentation condition according to the information detected by the state detection unit 19 and can determine whether or not the processing is completed. Specifically, the state detection unit 19 can detect the temperature inside the stirrer 15, the humidity of the discharged gas, the temperature of the gas, or the amount of water separated in the cooler 14 and transmit it to the fermentation setting unit 12 . The fermentation setting unit 12 determines whether or not the process is completed based on the information transmitted from the state detection unit 19 or sets the internal temperature of the cooler 14 or the stirrer 15 to be transmitted to the control unit 11 .

When the food waste is put into the stirrer 15 through the inlet D, the weight of the food waste put into the stirrer 15 by the weight detection unit 131 like the load cell can be detected and transmitted to the control unit . When the loading port D is closed, the lock detecting unit 132 can detect the locked state of the loading port D. [ When the locked state of the inlet D is transmitted to the control unit 11, the control unit 11 can start the operation for processing the food waste.

The stirrer 15 may be in the shape of a hollow drum or cylinder, and may be rotated by a rotating shaft. An agitating blade is disposed on the rotating shaft so that the food waste is mixed in the fermentation process. The stirrer 15 can be made in a closed structure and can be made in a structure capable of adjusting the internal temperature. The food waste is stirred in the stirrer 15 and fermented. The gas containing moisture generated in the fermentation process can be discharged to the cooler 14 through the discharge port formed in the stirrer 15 . And the water can be separated as the exhaust gas in the cooler 14 is cooled. Thereafter, the separated gas becomes dry air and becomes an inflowing gas together with the air introduced from the outside through the air inflow unit 18, and can be introduced into the agitator 15 again. An inlet for introducing an inflow gas into the stirrer 15 may be formed and an outlet tube and cooler 14 for connecting the stirrer 15, the cooler 14, the stirrer 15 and the cooler 14, 15 may form a gas circulation path. In addition, as the gas generated in the fermentation process of the food waste is circulated and cooled, the moisture can be continuously removed and the smell can be removed.

The cooler 14 can include a compressor, a condenser, and an evaporator, and the temperature of the exhaust gas can be maintained at a temperature that allows condensation of the water vapor contained in the exhaust gas, such as, for example, 5 ° C or -1 ° C.

The outside air can be introduced into the exhaust tube and mixed with the exhaust gas before the exhaust gas enters the cooler 14. [ And may be introduced into the cooler 14 together with the exhaust gas while lowering the temperature of the exhaust gas. Or the outside air may enter the inlet tube and mix with the incoming gas and enter the stirrer 15. The external gas may be formed on the front side or the rear side of the cooler 14. The air inflow unit 18 may be made into a through-hole structure connected to the discharge path or the inflow path. The pressure of the gas is reduced due to the flow of gas inside the discharge tube or the inlet tube so that the external gas can be introduced into the outlet tube or the inlet tube due to the pressure difference. Such an inflow structure of the external gas prevents the exhaust gas from being discharged to the outside during the inflow of air from the outside, and at the same time, a stable circulation structure is formed.

Control of the amount of exhaust air from the agitator 15 to the cooler 14, adjustment of the temperature in the cooler 14, adjustment of the amount of incoming air from the cooler 14 to the agitator 15, May be made by the circulation unit 16.
