The present invention is the invention of the patent application No. 2005-130218 relating to a method and apparatus for inorganic materialization (dissipation) of organic food waste using microorganisms, more specifically, 25 to 70 ℃ when processing food waste using microorganisms It can be applied to all aerobic microorganisms that are active in the environment, 1) to prevent overloading by stirring, and to prevent overload, and 2) to maximize the self-cleaning effect of the natural system by providing the optimal environment for microbial activity by supplying sufficient oxygen and moisture. The present invention relates to a food waste extinction method and apparatus for reducing environmental pollution caused by food waste by effectively decomposing and extinguishing food waste into inorganic materials in a shorter time.

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 lack of technology, the government is trying to improve by investing a lot of money, but there is no clear solution. .

In this regard, the government has enacted the 'discharge self-disposal method' among the food waste disposal methods. Among self-disposal method of food waste, 'self-extinguishing method' is attracting the special attention of the industry with new technology, and it is marketed by experts to be more than 100 billion won per year and the necessity in all households. According to the pink prediction that it will be caught, mass production of defective processing equipment by business owners who have been founded like a bamboo shoot without any clear technical solution is fooling consumers and causing the trust of the industry to bring about the crisis of abolishing the entire industry. to be.

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 Coagulation prevented the decomposition of other food waste, killed microorganisms, inhibited smooth emissions, and worsened during cold winter seasons.

In addition, the conventional food waste extinction treatment device is too short, the microorganisms are living organisms, so if you continue stirring and pulverizing continuously without moving only extremely limited extinguishing and decomposition action is a problem that the efficiency is significantly reduced There was this. 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, it can be applied to the whole aerobic microorganisms active at 25 to 70 ℃ during food waste treatment using microorganisms, 1) to prevent overload by agitating phenomenon when stirring 2) Maximize the self-cleaning effect of nature by providing the optimal environment for microbial activity with sufficient oxygen supply and moisture discharge and effectively decompose and destroy food waste into inorganic matter in a shorter time to reduce it to nature.

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

First, it is divided into anaerobic and aerobic microorganisms according to the temperature at which food waste 3 can be decomposed. The aerobic microorganism is actively decomposed at a temperature of 20 to 55 ° C., and is actively decomposed at a temperature above or below. Microorganisms that are called anaerobic microorganisms. Among these aerobic microorganisms, microorganisms that decompose at a temperature of 45-55 ° C. are known to have good degradability.

The microbial input process (S100), the particle size of the wood chips in the range of 4 to 8 mm in the stirring tank 10 surrounded by the heater 50 is heated to a temperature of 25 to 55 ℃ range that is good for microbial decomposition activity (2) is introduced into the 35 to 45% by volume with respect to the stirring tank 10, and is an initial step of adding a liquid microorganism in proportion to the capacity of the stirring tank 10, the survival of the microorganism provided by the present invention Due to the optimal environment for activities, microorganisms, which have been continuously injected about once a month, need to be replenished only once in the first or one to two years.

Next, the microorganism culture process (S200), while spraying the hot water 6 in the range of 30 to 70 ℃ 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 30 to 70 ℃ is to use the temperature set in advance because the temperature supplied to the microorganism due to various heat loss in the process of being supplied 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.

Next, the food waste input process (S300), the food waste so that the range of 45% by volume or less with respect to the stirring tank 10 through the cover 71 attached to the upper front side of the frame 70 of the stirring tank 10. (3) It is a process to inject.

Next, the food waste decomposition process (S400), by spraying the hot water 6 in the range of 30 to 70 ℃ periodically in various directions using a nozzle 54 from the top to wash the mucus generated by the microorganisms while stirring the tank (10) The mixing and pulverization and the pause by the stirring blade 30 installed in the center is repeated for 10 to 14 hours while inorganic food waste (3).

In addition, the oxygen supply and wet air discharge process (S500) is made at the same time as all of the above, and is supplied from the blower or fan 61 through the air inlet 62 is formed to be vented from the upper side of the stirring tank (10) Consisting of sufficient oxygen is supplied by the external dry air to be at the same time the internal wet air is pushed out and discharged through the overflow water discharge port 63 located on the other side of the upper air supply and wet air discharge process (S500); consisting of, all the processes Due to the condensation of the hot water (6) and the heat generated during the digestion and decomposition of the microorganisms in the stirring tank (10), the condensation is condensed and eventually falls on the mixture of food waste (3) and wood chips (2) Will form. This water film causes the microbes to be killed by blocking the oxygen supplied to the microorganisms, and forcibly introduces oxygen using a blower or a fan 61 to supply a sufficient amount of oxygen to the microorganisms which are exponentially increased by the culture. Simultaneously with the inflow, it will be discharged by pushing the wet air and peculiar food odor through the overflow water outlet 63 is installed on one side. By the oxygen supply and wet air discharge process (S500), the humidity of the internal air is controlled and oxygen is continuously supplied to prevent water film generation and to deodorize the unique food smell so as to be used smoothly.

In addition, a rubber packing 711 is installed inside the cover 71 installed on the upper portion to prevent a specific food smell from entering the room, thereby improving the use environment.

Since the food waste decomposition step (S400) after 5 hours, most of the organic food waste is decomposed and extinguished, and only a small amount of foods including the lime component remain, so that other food waste can be re-injected into the food waste input process (S300). Can be circulated.

In addition, the microbial culture step (S200) and food waste decomposition step (S400), the spraying and stirring step of mixing and grinding by the stirring blade 30 while spraying hot water 6 using the nozzle 54 from the top (S600); A stirring step (S700) of mixing and pulverizing by the stirring blade 30 without spraying hot water 6; While discharging the liquid containing the inorganic falling to the lower portion of the stirring tank 10 along the discharge guide 40, the lower perforated portion 12 of the stirring tank 10 at the same time the first and second cleaning nozzles (41, 42) Washing step (S800) to wash using; It is subdivided into a stop step (S900); to stop the operation, such as stirring and washing, and to wait for the microorganism to actively incubate and decompose. The pause process (S900) is so important that it is not an exaggeration to say that it is the most important of all the processes. Microorganisms are also living organisms, which stop their activities during continuous stirring and grinding, resulting in extremely limited 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, 10 minutes, 30 seconds, 60 minutes and 60 minutes, respectively. Low stage which is ℃; Stops at 1 minute 30 seconds, 15 minutes, 40 seconds, 60 minutes and 60 ° C., respectively; Each 3 minutes, 10 minutes, 40 seconds, 60 minutes and 60 ℃ high stage; divided into several stages according to the amount and quality of food waste, the user can selectively drive.
