Description

Apparatus for disposing food garbage

The present invention relates to a food waste processing apparatus, and more specifically, to decompose and destroy food wastes by dehydrating organic waste foods to maintain proper moisture, and then crushing and cutting them and fermenting them with aerobic microorganisms. And it relates to a food waste fermentation processing apparatus that can reduce the processing cost by preventing the environmental pollution caused by food waste by reducing the nature to be able to fertilize to reduce.

Food waste is very large and contains a large amount of water, so it is easily decayed. Also, it is composed of organic matter, and when it is landfilled, leachate is generated and contaminates soil and groundwater. Odor can cause severe environmental problems, and when incinerated, it contains a lot of water, so the efficiency of incineration is inferior.

When food waste is filled with organic matter with lots of protein, carbohydrates, fats, and fiber, landfills are contaminated with groundwater due to leachate from landfills and environmental pollution due to harmful gas generation is required.

Recognizing this, the government already banned landfilling of food waste on January 1, 2005. Separate discharge is mandatory at home, and tourist accommodation and farm and marine products, including restaurants with a capacity of 125 square meters or more, or group meals for groups of 100 or more. Large-scale stores of more than 3000 m², such as Cacter, are making legislative measures to reduce food waste by themselves to prevent costs and environmental pollution.

Therefore, due to the serious environmental pollution problem, a new perception about the disposal of food waste is emerging. Due to these demands, many treatment methods have been proposed and distributed to treat food waste from a new angle. However, most of the methods for reducing food composting have been carried out, and the feed method using food residues is limited to some livestock farms.

Food residues generated in large restaurants, catering establishments, and general restaurants are composted or reduced, and only a part of them are recycled and most of them are disposed of as landfills, causing serious environmental pollution.

Specifically, various types of disposers that are being developed to treat food residues in the sink of the kitchen in the near future are discharged in the state of waste which is dehydrated and dried to facilitate the separate collection of the processed food residues. .

The food waste discharged from the disposer is discharged only by reducing the volume of the food waste, and since it is discarded as it is, the landfill and landfill costs are excessive, and the environmental pollution by food waste is prevented. It is not possible to achieve the ultimate goal.

Therefore, the use of food waste as feed or organic compost is to prevent the environmental pollution caused by the waste from food residues, and to provide a device or an effective treatment method that can achieve this purpose, Will be achieved.

The method and apparatus for feeding or fertilizing food residues have increased the interest in environmental pollution, resulting in the emergence of various methods.

Organic fertilizers produced using food residues can lead to increased production and stabilization of the soil while preventing environmental pollution, which can be a popular fertilizer. Therefore, there are steady attempts to utilize food wastes as feed or fertilizers. have.

Representative processes that make up the mainstream among the recently known foddering methods are crushing, sterilization, feeding or dehydration, crushing, side feed, drying, feeding system is applied, and this foddering method is considered to be the most effective. The method of feeding foods in liquid form using food residues is not only very primitive, but also poorly sanitary, by simply crushing and sterilizing the collected residues. In addition, in the summer season, there are many difficulties in controlling the supply and demand of feed due to decay of the residue, and there are also problems in securing the feed, and excessive fuel costs for drying are accompanied by operational difficulties.

In addition, most of the feed made of food waste has a unique smell of food, especially in the process of manufacturing dry feed, a bad odor occurs in the process of evaporating moisture, causing a problem of complaints.

In addition, almost all of the known methods for feed production have adopted a method of fermenting at a high temperature for a predetermined time by adding a microbial agent called a fermenting agent in the process of sterilizing or drying food waste. However, the function of microorganisms can not function for a short time, and most microorganisms can not survive above about 60 ℃, microorganisms beneficial to the intestine of the livestock grow mainly at medium temperature, so in high temperature fermentation, it is almost killed, and with livestock No microorganisms are supplied to them.

After all, the conventional high-temperature fermentation is considered to be derived from the concept of composting, fermentation applied to the exact concept of the feed should be made because the quality of the feed is of no effect to the livestock as well.

Therefore, if you know the general fermentation concept and use fermentation agent, there is no use of unnecessary microorganisms, and if you use microorganisms in well-selected fermentation process, you can not only improve the quality of feed but also prevent environmental pollution from food waste.

Food waste, which is an essential part of our daily lives, accounts for about 17% of our country's total waste.In the past, landfill methods to dispose of food waste are landfills due to groundwater contamination of leachate and odors in landfills. It is a very difficult reality to do. In view of this reality, in order to effectively treat food waste, various technologies such as annihilation, feed, composting and drying by fermentation have been developed, and some technologies are commercialized and are in the commercial stage. However, since the water content of food waste is high, about 80%, decay occurs quickly and bad odors are generated. Therefore, odor gas must be removed during the treatment process. In addition, methods such as pyrolysis, catalysis, and the like for treating malodorous gases also consume excessive amounts of energy. In addition, the general activated carbon adsorption method uses refrigeration technology to maintain a low temperature, and also consumes a lot of energy. Therefore, the development of food waste odor gas treatment system technology that can save energy while removing moisture and effectively removing odor gas. This is urgently needed.

There are two ways to treat food waste effectively: resource recycling and discharger self-treatment.

The resourceization method is a desirable way to solve the practical problem of lack of resources. However, in order to make food wastes into resources, huge facilities and costs are required. Therefore, they cannot be installed in general homes or restaurants, and are collected and transported to an equipped treatment plant.

Ejector self-treatment causes food wastes with a water content of 80-85% to easily decay and cause environmental damage due to odors during transportation.

The fermentation of food wastes can be made very easy to satisfy the fermentation conditions using fermentation heat, the use of power is reduced, there is no occurrence of odor and can effectively treat food wastes.

The present invention is to solve the above-mentioned conventional problems, and proposes a method of recycling the food waste by the discharger self-processing method. This food waste treatment method is to cut the food waste to effectively handle the food waste using aerobic microorganisms, and to prevent the odor generated from the processor is dispersed in the atmosphere while providing the optimal environment for microbial activity, It provides a food waste fermentation processing device that can reduce the environmental pollution caused by waste.

The present invention can block the odor generated in the process of being cut and fermented into the main body by the odor blocking plate to spread to the outside, the odor discharged finely from the odor blocking plate is blocked on the cover while the inside of the cover The deodorant installed on the bottom prevents the spread of odor, and food waste, which is an organic substance containing a large amount of water, is removed by a significant amount of water by the primary and secondary separation networks. By cutting and pulverizing to an appropriate size while maintaining the moisture content, it is possible to have an environment in which food waste can be fermented.

In addition, the sewage discharged from the microbial fermentation tank is prevented from being discharged from the odor through the drainage pipes by the deodorizing material installed in the drainage pipes.

The food waste fermentation processing apparatus of the present invention cuts the microorganisms to quickly approach the organic matters so that they can be decomposed prematurely during the processing of the food wastes using the aerobic microorganisms, and provides an optimal environment in which the microorganisms can be inhabited by a heater. It can be easily and cheaply fermented and used as fertilizer or feed to effectively treat food waste while significantly reducing facility and maintenance costs, and to prevent the occurrence of odor at the source. Since it is possible to install anywhere where needed, it becomes very easy to dispose of food waste.

Therefore, environmental pollution due to food waste can be reduced by removing odor and economic maintenance cost.
