Description

Livestock manure odor remover {DEODORANT FOR LIVESTOCK EXCRETION}

The present invention relates to a livestock excreta malodor remover capable of resolving civil complaints caused by stench of various kinds of manure in livestock farms, and facilitating fertilization of manure.

In livestock farms, methane gas, carbon monoxide, hydrogen sulfite, digestion gas, ammonia gas, etc. are generated from the manure of pigs, chickens, cattle, etc. It causes not only air pollution but also water pollution.

On the other hand, although manure is an organic material, it has a high value as an organic fertilizer, and can be composted through aerobic fermentation by microorganisms. However, the severe odor generated during the composting process using livestock manure can cause great damage to nearby residents. Therefore, if it is possible to remove the odor generated from livestock manure, it will be useful for producing odor-free compost.

Accordingly, there has been development of strains capable of removing various odors. However, there has been a problem in that the actual odor cannot be properly removed in the odor removal and composting using most strains.

As an example, Korean Patent Registration No. 10-1120095 discloses a method for passing or adsorbing pig manure odors by using citrus tree sawdust and manure compost together with malodor reducing microorganisms. Republic of Korea Patent Publication No. 2012-0068194 discloses a composition consisting of a mixture of forestry by-products such as bamboo leaves and pine needles, lactic acid bacteria (Lactobacillus parakefili) and yeast (Candida glabrata), and anhydrous glucose in 10 to 30 wt% of livestock manure fertilizer. Disclosed is a method for removing the odor of livestock manure by mixing. However, according to the above technology, the treatment efficiency of artificially cultured microorganisms shows a large deviation depending on the degree of decay of the manure, and the material used for reducing the odor of livestock manure is difficult to supply and demand, and it is not suitable for large-scale livestock manure treatment. . In addition, Republic of Korea Patent No. 10-0378667 discloses a method of composting a composition of odor-decomposing microorganisms by mixing 5 to 10% livestock manure and aerobically fermenting the mixture with sawdust, rice husk and leaf powder. Republic of Korea Patent No. 100848677 discloses 30-50 parts by weight of humus soil, 10-30 parts by weight of woody clay, 5-20 parts by weight of quicklime, 5-20 parts by weight of waste fossils, 0.5-2 parts by weight of thermophilic microorganisms based on 100 parts by weight of chicken manure Disclosed is a method of mixing parts and fermenting at a temperature of 50 to 60° C. for 5 to 7 weeks. However, in the case of the above patent, the amount of excipients input is large compared to the amount of manure to be treated, which is very inefficient, and it is impractical to require mechanical equipment investment required for large-scale treatment.

Accordingly, in order to minimize the occurrence of civil complaints, deodorants with the main purpose of removing odors have been developed. An example thereof is Korean Patent Laid-Open Patent Publication No. 10-2020-0016791, which relates to a composition for removing the odor of livestock manure, and provides a composition for removing the odor of livestock manure, characterized in that it includes metal chlorides (Metal Chlorides), an organic acid and water. In this case, since metal oxides and organic acids are included, it is excellent for removing odors, but on the contrary, composting of livestock manure is impossible.

The present invention has been devised to solve the above problems, and the livestock manure malodor remover, which is an embodiment of the present invention, is a mixed fruit flavor comprising ethyl butyrate, ethyl vaseline, and fruit flavored oil for alleviating the odor of livestock manure. matter; and a retention agent comprising any one of glycerin and dextrin for delaying the fragrance emission of the mixed fruit flavor material.

Here, the livestock manure malodor remover may further include a yeast extract for the steaming of the livestock manure.

Here, the fruit mixed flavor material may include 10 to 30% by weight of the livestock manure odor remover.

Here, the yeast extract may include 10 to 30% by weight of the livestock manure malodor remover.

Here, the retention agent may include 40 to 80% by weight of the livestock manure odor remover.

Here, the mixed fruit flavor material may include fruit flavor oil.

According to an embodiment of the present invention having the above-described configuration, it not only alleviates the odor of excrement by capturing various odor components generated in the excrement, but also sterilizes various microorganisms present in the excrement and the like existing deodorants sold on the market. Compensating for the disadvantage that it cannot function as compost, it does not remove microorganisms present in the compost, but activates microorganisms to improve the steaming of the compost, thereby facilitating composting.

1 and 2 are images showing the microbiological test results of the control group and the example of the present invention for confirming the steaming effect of an embodiment of the present invention.

Hereinafter, the present invention will be described in more detail through examples that do not limit the present invention.

The main raw materials of the livestock manure malodor remover according to an embodiment of the present invention are mixed fruit flavor, yeast extract, and glycerin (or dextrin). Among the ingredients of mixed fruit flavor [trade name: LJ1-0215, production source Hanbul Chemical Co., Ltd.], ethyl butyrate, ethyl vanillin, orange oil (fruit flavor oil), etc. are included. These components play a role in alleviating the odor of livestock manure.

Yeast extract is used as a kind of growth aid that helps the growth of various bacteria in the compost when manure is manufactured into compost. Glycerin is used as a kind of retention agent (the role of allowing the fragrance component to volatilize slowly and holding the yeast extract) used to make a liquid formulation by mixing fruit flavor and yeast extract with glycerin. In addition, dextrin (cyclodextrin or malodextrin) may be added instead of glycerin to prepare a powder formulation.

In the livestock manure malodor remover according to an embodiment of the present invention, if too much of the mixed fruit flavoring material is used, when mixed with the malodor from livestock manure, it is converted into a sensually unfavorable odor. Since it cannot be controlled, the range of use of the mixed fruit flavor is 10 to 30% by weight. As the yeast extract, all kinds of commercially available yeast extracts can be used. The more yeast extract is used, the greater the compost steaming effect, but it is an expensive raw material. Therefore, considering the economical aspect, 10 to 30% by weight is suitable. Glycerin (or dextrin) used as a retention agent is included in an amount of 40 to 80% by weight in consideration of the amount of the mixed fruit flavor and yeast extract described above. .
