Description

The present invention relates to a liquid fermentation treatment device for food waste, in particular to a food waste using microorganisms that can filter the solid matter and discharge water of food waste treated by microorganisms through multi-stage inclined surfaces and discharge purified water through the water purification process Liquid fermentation processing device.

Recently, with the development of various catering industries, the amount of food waste such as food waste and food waste (Food Waste) has shown geometric multiple growth.

The amount of food waste as recorded above accounts for almost 1/3 of the total amount of garbage, and because of its high decay rate, it causes serious stench, and further becomes a serious social problem because of the high processing cost and high moisture content.

At present, as a processing method of food waste, for example, a landfill method and a metered garbage bag method are used. The landfill method is difficult to guarantee the landfill site for food waste, and it will release a variety of pollutants because it contains a lot of protein, carbohydrates, fat, cellulose and water, which will further cause groundwater pollution due to leachate, and will Serious environmental pollution problems such as air pollution are caused due to generation of harmful gases. The metered garbage bag method causes a bad smell due to rapid spoilage of food waste contained in the bag and thus causes a problem that it is difficult to find specialized manpower for its disposal and collection work.

In order to solve the above-mentioned problems, such as drying, crushing, and microbial treatment methods are used in households and restaurants to treat food waste by themselves. Because the drying type must use a heating element to dry food waste in order to reduce the moisture content, there are problems of high power costs, severe odor, and the risk of electric shock accidents. The pulverizing type must use the rotating blades to pulverize and crush the food waste and then discharge it through the downpipe. Therefore, it is difficult to ensure the installation space, the installation cost is too high, and about 80% of the food waste must be recycled after pulverization. The microbial treatment method, which stirs food waste with microorganisms and performs fermentation treatment, is extremely efficient and can solve various problems in the previous methods at the same time, so a lot of research activities related to it are actively being carried out.

In addition, in the Republic of Korea Registered Patent Publication No. 10-1877400 (2018.07.05), a food waste enzyme fermentation decomposition and reprocessing device is proposed, which includes: a first stirring part for the first stirring of the composite bacteria; The second stirring part is used for second stirring the product stirred in the aforementioned first stirring part; the discharge part is used for discharging the discharge water treated in the aforementioned second stirring part; the first stirring part shaft, It is used to drive the stirring blades of the first stirring part to rotate; the second stirring part shaft is used to drive the stirring blades of the second stirring part to rotate; the motor shaft is connected to the first stirring part shaft and the second stirring part through the drive belt Shaft connection, used to transmit rotational force; drive motor, used to provide driving force to the aforementioned motor shaft; drive belt, connected to drive the aforementioned first stirring part shaft and second stirring part shaft and the motor shaft at the same time; tension The part is installed between the shaft of the first stirring part and the shaft of the second stirring part, and is used to apply tension to the driving belt; the power input part is used to supply the electric power transmitted from the outside of the main body; The water supplied from the outside of the main body is supplied to the food waste; the hot water tank is used to supply the hot water supplied from the outside of the main body to the food waste; the hot water discharge port is used to discharge the treated water to the outside of the main body; The solenoid valve is used to electronically switch the respective valves of the supply port and the hot water discharge port; and the control board includes control instructions for controlling the driving motor and the solenoid valve.

No. 4 stipulates that the weight of the solid matter discharged together with the effluent water after the food waste passes through the recycling process of the corresponding facility shall not exceed 20% of the weight of the solid matter inflow), and There is further a problem that solid matter accumulates in the sewer pipe with the passage of time and causes damage to the function of the sewer pipe.
