The present invention relates to a method and apparatus for inorganic materialization (dissipation) of organic food waste using aerobic microorganisms, and more particularly, when treating food waste using aerobic microorganisms 1) microorganisms quickly approach the organic matter and early decomposition Cutting, softening and grinding to make it possible, 2) premature mixing during agitation, and 3) maximizing the self-cleaning effect of nature by providing an optimal environment for microbial activity, thus reducing food waste minerals in a shorter time. The present invention relates to a food waste extinguishing method and apparatus for reducing environmental pollution caused by food waste by effectively decomposing and extinguishing and reducing it to nature.

Food waste (Food Waste), a representative organic food waste, has emerged as the biggest environmental pollution problem in the 21st century. In Korea, landfilling methods have been used for decades, but food waste, which is rich with protein, carbohydrates, fats, and fiber, emits various pollutants when it is landfilled. Severe environmental pollution such as air pollution caused.

Recognizing this, the government has already banned landfills of food waste on January 1, 2005, and it is mandatory for households to separate and discharge food wastes, including more than 125 square meters of restaurants or catering groups of 100 or more, 3000 Large-scale stores of more than ㎡, ie, agricultural and fisheries centers, are required to reduce food waste by themselves, making it legal to impose up to three years imprisonment or fines of up to 20 million won for violations (Article 15, Paragraph 3 of the Waste Management Act). Article 9-2

Food waste generated 1000 tons per day is a waste of resources worth 14 trillion won per year, which is a huge waste of two more airports in Incheon, and the government has made resources for food waste, compost or feed. We are doing our best to recycle them, but we have yet to produce other wastes due to immaturity of treatment technology and equipment, so we can't find a clear solution. There was no big problem.

So far, food waste disposal methods can be largely divided into 'resourceization methods' and' exhausters' self-disposal methods'. It is a preferred method. However, since the recycling method of food waste requires huge facilities and costs, it cannot be installed in general homes or catering establishments, so it is transported to the treatment plant where the equipment is installed and disposed of, and food waste having 80 to 85% moisture content is disposed of. Easily decayed, the odor, sewage and salinity during transportation revealed the limit of composting, and due to the lack of technology, the government is trying to improve by investing a lot of money, but there is no clear solution. to be.

In this regard, the government has enacted the 'discharge self-disposal method' among the food waste disposal methods. Among the food waste self-treatment methods, in particular, 'self-extinguishing method' is attracting the industry's extraordinary attention with new technology, and the experts make the market potential of more than 100 billion won per year and the necessity in all households. According to the pink prediction that it will be produced, the business owners who started like a bamboo shoot without a clear technical solution are producing ridiculous treatment equipment, fooling consumers and losing the trust of the industry, and bringing about the crisis of the entire industry. .

The conventional food waste extinguishing treatment device is formed in a shape of a simple spatula without a stirring function due to the lack of technology, so that organic matters having a circular shape, such as green onion, radish, and cabbage leaves, are hardly processed. There was a problem, and it did not consider the survival environment of microorganisms, which revealed the limitation of processing time and processing capacity of food waste, and caused a lot of defects such as stopping by overload caused by food waste caught between stirring blade and stirring tank. There was a problem that could not be used.

In addition, when decomposing food waste using microorganisms, the devices manufactured without properly grasping the microorganism's characteristics and proper environment are not effectively decomposed due to inadequate microbial activity. Since the membrane is formed by the mucus composed of sugar, peptine, etc., there is a problem of blocking the inflow of oxygen and killing microorganisms.

In addition, the conventional food waste extinction treatment device is operated at a temperature lower than the temperature at which fat components such as pork oil (28 ~ 48 ℃) and tallow (beef oil, 36 ~ 50 ℃) solidifies, in the stirring tank and the outlet There is a problem that the coagulation prevents the decomposition of other food waste, kills microorganisms, inhibits the smooth discharge, and worsens during the winter season when the temperature drops.

In addition, the conventional food waste extinction treatment device is too short, the aerobic microorganisms are also living organisms, so if continuously stirred and pulverized, they do not move but only have a very limited digestion and decomposition action, resulting in a significant drop in efficiency. There was a problem. This was a problem caused by not considering the microbial position and living environment at all.

The present invention is devised to solve the conventional problems as described above, 1) when processing food waste using aerobic microorganisms 1) cutting, soft, grinding to enable early decomposition of microorganisms to quickly approach organic matter, 2) stirring 3) Maximize the self-cleaning effect of the natural world by providing the optimal environment for microbial activity, and effectively decompose and destroy food waste into inorganic matter in a shorter time to reduce it to nature.

Food waste extinction method using the aerobic microorganism of the present invention is largely composed of a microorganism input step (S100), microbial culture step (S200), food waste input step (S300), and food waste decomposition step (S400).

First, microorganisms capable of decomposing food waste 3 can be largely divided into anaerobic microorganisms and aerobic microorganisms according to temperature. Aerobic microorganisms actively decompose at a temperature of 20 to 55 ° C., and above or below temperature. Microorganisms that actively decompose in are called anaerobic microorganisms. Among aerobic microorganisms, microorganisms that decompose at temperatures of 45-55 ° C. are known to have good degradability.

Next, the microbial culture step (S200), while spraying the hot water 6 in the range of 50 to 60 ℃ periodically in various directions using the nozzle 54 from the top stirring blade 30 installed in the center of the stirring tank (10) Is a process in which mixing, pulverization and rest are repeated for 8 to 12 hours. The temperature of the hot water 6 is in the range of 50 to 60 ℃ is to use the temperature set in advance because the temperature supplied to the aerobic microorganism due to various heat loss in the process of supply is about 5 ℃ low. The conventional apparatus is to provide an optimal culture environment by supplying hot water (6) that maintains the proper temperature in accordance with the characteristics of microorganisms and survival environment of the cold water.

The pause process (S900) is so important that it is not an exaggeration to say that it is the most important of all processes. Aerobic microorganisms are also living organisms, which do not move during continuous stirring and pulverization, while remaining extremely limited in digestion and decomposition. Therefore, in the present invention, in consideration of the behavior of the microorganisms, the time spent more than agitation and grinding in the resting process (S900), the mineralization operation is very effective.

In addition, the driving time and the temperature of the hot water of the stirring and watering step (S600), the stirring step (S700), the washing step (S800) and the resting step (S900) are 1 minute, 8 minutes, 20 seconds, 70 minutes and 50 minutes, respectively. Low stage which is ℃; Stops at 1 minute 30 seconds, 10 minutes, 30 seconds, 90 minutes and 55 ° C., respectively; Each 2 minutes, 15 minutes, 40 seconds, 120 minutes and 60 ℃ high stage; divided into several stages according to the amount and quality of food waste, the user can selectively drive.
