And react with sodium ions and chlorine electrolyzed from food waste, and use various known salinity control devices such as a food waste desalination device composed of a water storage portion in which the negative electrode portion is replaced with NaOH and the positive electrode portion is replaced with HCl.

The mixing tank 600 is configured to mix the aerobic microorganism and the moisture control agent in the salinity control and sterilized food waste, and the aerobic microorganism and the moisture control agent are stored in the supply tank 610 and then supplied to the mixing tank 600. . The microorganisms are mixed so that the degradable organic components of the food waste are biologically oxidized by the microorganisms, and the moisture control agent functions as an additional function such as ion exchangeability and adsorptivity, and increases the water control effect as the functions vary. Economic effects can be expected that speed up processing time.

Fermentation tank (700, 700 ') is configured to ferment the food waste mixed with the aerobic microorganism and the moisture control agent, fermentation tank (700, 700') is preferably made of airtight. The fermenters 700 and 700 'mean fermentation, decomposition, synthesis, conversion, etc. using microorganisms, and the aerobic microorganisms are cultured and aggregated using organic substances of food waste as nutrients to form flocs. It is configured to decompose contaminants and clean up food waste.

According to a preferred embodiment of the present invention, the fermentation tank 700 is configured to feed food waste by fermenting food waste for one day. Through the spontaneous fermentation tablets as described above, the food waste is to be completed for livestock feed.

According to a preferred embodiment of the present invention, the fermentation tank (700 ') is a low-speed stirring tank 710 for the first fermentation at a temperature of 50 ~ 70 ℃ by receiving heat generated by the aerobic microorganism and the external heater 711 heat and And, the first fermented food waste consisting of a fermentation fermentation tank 720 for the second fermentation for 12 to 17 days, the storage tank 730, the storage tank 730 to receive and store the food waste is completed secondary fermentation It is further provided with a magnetic separator 740 for extracting and separating the iron from the food waste, it is configured to supply the separated food waste to the compost.

The low speed stirring tank 710 is configured to perform primary fermentation at a temperature of 50 to 70 ° C. when the heat generated by the aerobic microorganism and the heat generated by the microorganism are 6 or less, and is supplied with an external heater 711. If it is kept below the pathogen is not killed, if it is maintained above 70 ℃ sterilization is not performed because the primary fermentation is carried out at a temperature of 50 ~ 70 ℃.

In addition, the first fermented food waste is transported to the after fermentation tank 720 for the second fermentation for 12 to 17 days in the process of the second fermentation, if the secondary fermentation proceeds less than 12 days without composting If the secondary fermentation proceeds for more than 17 days, composting is no longer performed, so food waste is preferably fermented for 12 to 17 days for complete composting.

In general, the change in temperature is caused by the heat of fermentation, which serves as an indicator to determine the amount of CO2 generated by the microbial activity of food waste decomposition and the degree of decomposition of organic matter. In addition, the temperature of 50 ~ 70 ℃ of the fermentation process plays an important role to kill pathogens.

In addition, the composting process of food waste is mainly due to the aerobic oxidative decomposition of organic matter, the presence of oxygen, resulting in the conversion of carbohydrates to CO2, water, microbial cells, heat and decomposed corrosive substances. The air supplied to the aerobic fermentation process in the composting process allows the aerobic metabolism of microorganisms, and controls the temperature to remove moisture and remove CO2 and other gases.

Food waste tends to have acidic fermentation as it ages, lowering to less than 4.0, and a suitable pH for composting is known as 5.5 to 6.6.

In addition, the ratio of carbon and nitrogen (C-N ratio) is the most important factor for the denitrification rate to promote the effective composting of food waste due to the characteristics of organic matter to be degraded by microorganisms.

The aerobic denitrification rate suitable for composting is 26 to 35, and when it is higher than 35, nitrogen deficiency starts to appear, microbial proliferation is suppressed, and the composting rate may be slowed down.
