Description

High speed decomposition fermentation system of organic waste

The present invention relates to a fast decomposition fermentation apparatus of organic waste.

In particular, the present invention relates to a device for composting or feeding organic waste such as animal meal, feed residue and residue by fermentation under aerobic conditions, and more specifically, to organic waste. The present invention relates to a high-speed decomposition fermentation apparatus for organic wastes capable of rapidly mass fermenting organic wastes by forcibly adjusting air, moisture, and temperature so as to meet optimum growth conditions of native microorganisms.

With the rapid increase in population and living conditions, and the rapid increase in meat consumption, problems such as livestock stocks and feed residues and residues in large apartment complexes are raised as social concerns. There is a situation.

In the past, when small-scale farming was carried out, dumping of animal waste or fodder was carried out in nature. However, these wastes, which are aggregates of organic matters, are eutrophicated when they are urinated in rivers and dumped in soil. By promoting soil acidification, water and soil have been contaminated. This is also the case in the remainder.

However, such dumplings, feed residues and residues (hereinafter referred to as "organic waste") are currently prohibited by strong environmental legislation because they contaminate water quality and soil as described above.

Therefore, other treatment methods for organic waste have been devised, and incineration has been adopted as one method. However, the incineration method rapidly decomposes organic wastes, but in the process of incineration, it emits fatal substances such as methane cutlet, dust, and dioxin, and causes odors, resulting in collective complaints of neighboring residents.

Of course, such incineration methods have been conducted in various efforts and studies to overcome the above-mentioned disadvantages, but it has proved to be inadequate for the treatment of organic wastes such as animal waste or feed waste due to the inability to prepare fundamental measures. .

At present, the fermentation method, another method of treating organic waste, is welcomed from the viewpoint of environmental protection because it solves the above-mentioned drawbacks and at the same time can use organic materials obtained in the fermentation process as fertilizers of flowers and agricultural products or feed for livestock. have.

Prior arts using such fermentation methods are disclosed in European Patent EP009712A, which transfers and mixes organic waste to a belt conveyor, and British Patent GB300607A, which facilitates air circulation to organic waste in the chamber, which are described under aerobic conditions. Composting technologies for organic waste.

However, the above-described techniques are agitated fermentation treatment made under atmospheric pressure, and the oxygen supply is not smooth, causing anaerobic fermentation, and a long time is required to completely ferment.

Moreover, under the current legislation there are certain restrictions on their use, as these techniques result in water pollution as well as soil contamination when the final product, which is not completely composted, is used as a fertilizer for flowers or agricultural products. Is the fact of the state.

Therefore, the present invention has been made in consideration of the above problems, and its purpose is to ferment an organic waste, so that the air (oxygen), moisture (humidity) and heat to meet the optimum growth conditions of microorganisms growing in the organic waste. It is to provide a high-speed decomposition fermentation apparatus of organic waste that can quickly and directly ferment the organic waste by controlling the (temperature).

In addition, another object of the present invention is to utilize the final product fermented by the fermentation apparatus according to the present invention as a fertilizer of the flower or feed for livestock.
