Description

Food waste aerobic fermentation processing equipment {AEROBIC FERMENTATION- TREATMENT APPARATUS FOR FOOD WASTE}

The present invention relates to a food waste fermentation apparatus for fermenting food waste, and more particularly, to effectively create an aerobic atmosphere with a smooth input of air, to smoothly discharge the food without unilaterally stacking the waste, B) It relates to a food waste aerobic fermentation treatment apparatus to ensure that the remaining leachate is not penetrated into the drive unit to ensure the durability and operational reliability of the device.

In general, composting has been made in farms since ancient times. The composting method, which has been performed due to the self-sufficient needs of farmhouses, supplies oxygen by continuously placing straws and grasses in barn waste such as cattle and pigs in rural households and kitchen waste. And several months of anaerobic fermentation to produce very high quality compost.

In the 20th century, the generation of organic wastes such as food waste and livestock manure increased, and the composting method was applied to the disposal of these wastes. Therefore, anaerobic treatment requires aerobic treatment because of the slow composting rate. Accordingly, aerobic fermenters of various structures have been developed. As fermenters, various types of fermenters have been developed, such as beast type, rotary kiln type, auger type, multi-stage type, silo type, etc., but fermenters composed of a number of mechanically mixed open type structures are most commonly used.

For example, a fermentation apparatus, which is a main process of conventional food waste treatment, is composed of a primary fermentation tank and a secondary fermentation tank, and the primary fermentation tank is made of 8 to 16 concrete structures to adjust the water content by natural evaporation for about 15 days. After the first fermentation and fermentation by aerobic fermentation for about 6 days in a secondary fermenter consisting of a plurality of structures of mechanical mixing open type. Therefore, it occupies a lot of land area, has a large amount of air pollutant emissions, and the wastewater spills out from the bottom of the fermenter, which is a target of complaints due to the occurrence of odors around. Recently, instead of adjusting the water content by natural evaporation, the water content is adjusted by forcibly evaporating water within 24 hours by the circulating heat of the heating medium boiler, but the area is smaller than natural evaporation, but it consumes energy. .

In the case of the ripened fermentation tank, the prior art fermentation is carried out for more than 20 days in a building or outside a building, and is periodically agitated by a payloader or the like, which takes up a lot of land area and requires a long fermentation period due to anaerobic fermentation. .

In addition, as another example of food waste, a vertical cylindrical aerobic multi-stage continuous fermenter has been proposed, which is configured to supply air through a central shaft penetrating the fermenter, and thus there is a limit in creating an aerobic atmosphere because a smooth air supply is not achieved. In addition, the food waste stacked on the bottom of the fermentation tank is biased on one side or a part by the stirrer, there is a problem that the smooth fermentation product is not discharged.

In addition, the conventional multi-stage fermenter has a problem that the leachate generated during the processing or fermentation of food waste easily penetrates into the drive unit formed in the lower portion of the fermentation tank causing malfunction of the drive unit.
