Description

[0001] The present invention relates to an apparatus for fermentation of animal carcasses,

The present invention relates to an animal carcass fermentation apparatus, and more particularly, to an animal carcass fermentation apparatus capable of decomposing an animal carcass such as waste pigments, waste systems, waste wastes, slaughter by-products, and dead fishes by a fermentation method in a shorter time than before, The present invention also relates to an apparatus for fermenting an animal carcass which can produce an organic fertilizer with the fermented liquid produced.

In general, research on recycling of resources is being actively carried out, and interest in recycling of organic waste is increasing day by day. Among the organic wastes, in the case of food waste and livestock wastewater, technologies for introducing microorganisms or recycling them through composting and feed conversion through a fermentation process are reaching commercialization stage.

However, research and technological development of treatment apparatuses and treatment methods for treating animal carcasses such as dead animals, slaughter by-products generated during slaughtering process, and dead fish have been delayed. This is because, in the case of bulky animals such as cows and pigs, the disposal facilities and treatment methods are inadequate. As a result of these developments, recently, the form of livestock farming has developed from a small scale, small scale to an enterprise type, Once an animal has died, it is often the case that a large number of our animals are going to be carried out, and it is difficult to arrange facilities for disposal. In most cases, these animal carcasses have been treated mainly by landfilling and incineration. However, the landfill method of landfilling animal carcasses can jeopardize environmental pollution and health, such as contamination from leachate and bad odor that occurs even after landfilling, bacteria and pathogens in the process of decaying animal carcasses, A process for burning Environmental pollution can not be avoided in the same way as the landfill method.

Animal carcasses are rich in amino acids and proteins, and contain large amounts of microbial metabolites such as minerals, organic substances, minerals, and organic acids, which can be useful in plants and plants. In the past, landfill and incineration treatments However, there was a problem that valuable resources were wasted.

In recent years, methods for decomposing and treating animal carcasses by chemical methods such as acids or bases have appeared. Such a chemical treatment method has an advantage that pathogens and bacteria can be eradicated in the course of treatment, but there is a problem that the treatment cost for carrying out the chemical method is high, and the treatment process is complicated and difficult. In addition to the initial facility cost, it also takes a lot of operation cost to operate the equipment, and it is a reality that it is difficult to progress each process and it is not widely used in a small or small scale livestock farmers

Alternatively, a method of fermenting and treating an animal carcass using various microorganisms can be considered. This is advantageous in that the fermentation facility is relatively simple compared to the chemical plant, the processing cost can be reduced, and the processing process is not complicated.

However, such a fermentation treatment method can not produce optimum conditions (temperature, humidity, growth factor, etc.) in which fermentation is smoothly carried out, so that the treatment time is excessively longer than other methods and the fermentation efficiency to be fermented is relatively low there is a problem.

In addition, pathogens generated from animal carcasses during the fermentation process or before and after the process, or noxious gases or harmful substances generated in the middle of the process are directly discharged to the atmosphere, causing environmental pollution.

That is, the control unit can determine the time interval and the amount of the microorganism, the enzyme agent and the growth promoting agent to be injected, according to the type or number of the animal carcass inserted into the first fermentation unit 20 or automatically or according to the operator's instruction. The microbes, the enzymes and the growth promoting agent are moved along the reactant supply lines through the reactant feed lines 53, 63 and 73 according to the kind of the reactants, the time interval and the amount of the determined reactants, and then the reactant spray nozzles 55, 65, So that the first fermentation tank 29 can be uniformly sprayed. Thus, regular administration of the microorganism can increase the fermentation rate and maintain the high temperature state, thereby inhibiting the growth of the pathogen.

On the other hand, the microorganism used in this embodiment is Bacillus subtilis ), yeast ( Saccharomyces S. cerevisiae , Lactobacillus plantarum , L. acidophilus ), photosynthetic microorganisms ( Rhodobacter sphaeroides were each cultured in a selective medium. After centrifugation, the microorganisms were stored in a storage tank at a concentration of 2.3 x 10 ⁷ cfu / g. A stabilizer (30 ppm glucosylglycerol) was added to the microorganism storage tank 70 (2 ppm sodium chloride, 50 ppm nucleic acid, 1% molasses, 10 ppm magnesium sulfate, 5 ppm ferrous sulfate, pH 7.0) were mixed with an antioxidant (20 ppm BHT) and stored in the proliferation promoter storage tank Lt; / RTI >

When the microorganisms are injected, the growth promoting agent is also injected together. In this embodiment, the injected liquid is sprayed three times a day. Meanwhile, the microorganisms, the growth promoting agent, the stabilizing agent and the antioxidant described in the present embodiment are not limited to the above concentrations, and may be used in the range of 10 ppm-10,000 ppm depending on the kind.

On the third day after fermentation, the temperature reached 60 ℃. On the 6th day, it increased to 75 ~ 80 ℃ and then the internal fermentation temperature gradually decreased. Microbes and growth promoting agents were sprayed at intervals of 5 times a day from the 3rd to 6th day when the temperature rose. As shown in FIG. 8 (b) and FIG. 8 (c), some bones were observed in a state that they were not completely decomposed as shown in FIG. 8 (a) Liquid fermentation broth. The fermentation broth smelled a little ammonia and amine, but it did not feel bad smell.

The fermentation broth produced by the first fermentation unit 20 is transferred to the second fermentation unit 30 so that the fermentation process of the first fermentation unit 20 described above can be performed in the same manner. Unlike the first fermentation unit 20, the fermentation liquid is not a cadaver but a liquid fermentation liquid. Therefore, the solid by-product filtration unit 22 and the fermentation liquid filtration unit (not shown) 21 may be omitted. In addition, the reaction was carried out by adding gallium hydroxide (5N (normal)) for secondary sterilization as well as for potting. In order to artificially control the acidity and phosphorus content, phosphoric acid was added slowly to adjust the pH to 7.0. To promote absorption of nutrients, 0.05% boric acid, 0.2% magnesium sulfate, and 0.08% zinc sulfate can be mixed and used as a raw material for organic fertilizer. These trace elements and additives may be added in the second fermentation unit 30, but they may be performed in a post-treatment process (such as a processing step or a packaging step) after the fermentation step of the second fermentation unit 30 is performed will be. In addition, the concentration of the trace element may vary from 0.05% to 10% depending on the crop and method of use, and the type of the additive is not limited thereto.

The resultant fermented liquid was sprayed on the spinach at intervals of 3 days. As a result, as shown in Fig. 9 (b), the leaf color grew as the leaf color became darker and the leaf thickened. In addition, the overall growth of plants was increased by 1.5 times and rooting was also promoted. It can be seen that the growth was increased due to organic acids, amino acids, peptides, and enzyme solutions added to the fermentation broth.

Further, the sludge obtained after the fermentation is completed can be produced as powdery or granular form by mixing the adjunct materials (sawdust, zeolite, rice hull, etc.) and can be utilized as agricultural compost.

As described above, the present invention can produce a fermentation broth through a continuous fermentation process using a microorganism, and can easily produce an organic fertilizer at a farmhouse using the same. As described above, the organic fertilizer promotes vigorous plant growth, Respectively. It was also confirmed that the solid by - product obtained after the fermentation can be used as a raw material for organic fertilizer for grape - growing treatment.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the scope of the present invention is not limited to the disclosed exemplary embodiments. It will also be appreciated that many modifications and variations will be apparent to those skilled in the art without departing from the scope of the present invention.
