Description

아미노산 액상비료{Amino acid liquid fertilizer}Amino acid liquid fertilizer

본 발명은 아미노산 액상비료에 관한 것으로서, 보다 상세하게는 동물의 피(血)나 어류 사체, 또는 생선 부산물 등을 이용해 제조되므로 코스트가 낮은 열화학적 단백질 분해 아미노산 액상비료에 관한 것이다.The present invention relates to an amino acid liquid fertilizer, and more particularly, to a low-cost thermochemical proteolytic amino acid liquid fertilizer prepared by using animal blood, fish carcass, fish by-products and the like.

일반적으로 동물의 도축시 발생되는 부산물 중 피(血)는 털이나 내장 등과 같이 폐기 처분하여야 하며, 이를 식용할 수 없기 때문에 일부 재활용하고 소각처리하고 있다. 그러나 이와 같이 도축 폐기물의 재활용시 미생물에 의한 분해를 시키거나 분말화 시켜 첨가제로 사용하는 것이 대부분이다. 미생물에 의한 분해의 경우 비교적 넓은 부지가 필요로 하며 분해시 발생하는 악취는 대기 공해를 유발시켜 생활 환경을 오염시키게된다.In general, blood of the by-products generated during the slaughter of animals should be disposed of, such as hair or intestines, and some of them are recycled and incinerated because they cannot be eaten. However, most of these are used as additives to decompose or powder by microorganisms when recycling slaughter waste. In the case of decomposition by microorganisms, a relatively large site is required, and the odor generated during decomposition causes air pollution to pollute the living environment.

분말화의 경우 원가가 많이 먹히고 수요처가 많지 않아 많은량이 처리되지 못하는 문제점이 있다.In the case of powdering, a lot of cost is consumed and there is a problem that a large amount cannot be processed because there is not much demand.

또한, 어류의 양식사업이 활성화 되면서 녹조나 적조에의한 집단 폐사시 어류의 사체를 매립에 의존하고 있어 부패 하면서 발생하는 가스나 침출수가 지하수를 오염 시키고 있으며 매년 반복되는 대량 폐사로 양식장 주변 토양 및 지하수는더욱 오염되 가고 있다.In addition, as the fish farming business is being activated, the corpse of fish is reclaimed when landslides occur due to green algae or red tide. Thus, gas or leachate from decay pollutes the groundwater. Groundwater is becoming more polluted.

이상과 같이 도축된 동물의 피나 어류의 사체와 생선 가공 부산물,또는 어류 부산물을 이용하는 저렴한 가공 방법이 개발 되어야 할것으로 사료된다.As described above, inexpensive processing methods using slaughtered animal blood, fish carcasses and fish processing by-products or fish by-products should be developed.

본 발명은 전술한 바와 같은 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 동물의 피(血)나 어류 사체 또는 생선 부산물, 어류 부산물 등을 이용하여 제조되므로 원가가 절감될 뿐만 아니라 간단하게 처리하여 제조되는 새로운 아미노산 액상비료를 제공하고자 하는 것이다.The present invention is to solve the problems as described above, the object of the present invention is manufactured using animal blood, fish carcasses or fish by-products, fish by-products, etc., not only reduce the cost but also simply It is to provide a new liquid liquid fertilizer prepared.

본 발명에 따르면, 동물의 피(血), 어류 부산물, 생선 사체, 생선부산물 등과 같은 고형의 유기물인 피가공물에 단백질을 가수분해 시키기 위해 칼륨(k) 등 알칼리 성분을 물과 함께 첨가하고, 단백질분해효소이면서 에스테르 결합을 가수분해시키는 키모트립신을 첨가한 후, 가압 가열하여 피 가공물을 액상화 시킨 것을 특징으로 하는 아미노산 액상비료가 제공된다. 칼륨은 황산칼륨과 함께 칼리 비료의 원료이기도 하다.According to the present invention, an alkaline component such as potassium (k) is added together with water to hydrolyze the protein to a solid organic product such as animal blood, fish by-product, fish carcass, fish by-product and the like, and the protein The amino acid liquid fertilizer is characterized in that the lysase and hydrolyzed chymotrypsin for hydrolysis of the ester bond, followed by pressurized heating to liquefy the workpiece. Potassium, along with potassium sulphate, is also a source of cauliflower.

이하, 본 발명을 상세히 설명하면 다음과 같다. 본 발명에 의한 비료는 유기질 아미노산 액상비료로서, 다음과 같이 제조된다.Hereinafter, the present invention will be described in detail. Fertilizer according to the present invention is an organic amino acid liquid fertilizer, is prepared as follows.

먼저, 동물의 피(血) 또는 어류 폐기물,생선 부산물, 어류 사체등 피 가공물을 반응탱크에 넣고, 물과 함께 칼륨, 또는 수산화칼륨등 강알칼리를 첨가한다.First, animal blood or fish wastes, fish by-products, fish carcasses, and the like are put in a reaction tank, and strong alkalis such as potassium or potassium hydroxide are added together with water.

이때 물은 반응탱크에 담은 피 가공물이 잠길 정도로 붓는다.At this time, water is poured to the extent that the workpiece in the reaction tank is submerged.

상기 알칼리 성분으로는 화학 비료의 주성분인 칼륨이나 수산화칼륨을 이용하는 것이 바람직하다. 이러한 강알칼리는 유기물의 단백질을 가수분해시키는데, 그 사용량이 크게 제한 받지는 않으나 비교적 많은 양을 사용하게 되면 최종 생성물인 유기질비료가 강한 알칼리성을 나타내게 되므로 바람직하지 않다.As said alkali component, it is preferable to use potassium and potassium hydroxide which are main components of a chemical fertilizer. Such strong alkali hydrolyzes the protein of the organic matter, but its amount is not greatly limited, but if a relatively large amount is used, the organic fertilizer as a final product shows strong alkalinity.

또한 알칼리성분을 적게 사용하는 경우에는 단백질의 가수분해가 느리게 진행되므로 후술하는 가압 가열과정에서 가수분해가 촉진되도록 상대적으로 높은 압력과 높은 열을 가하여 장기간 처리하여야 하므로 비경제적이다. 바람직하게는 순도 48 ~ 51중량%의 칼륨 등을 사용하는 경우에는 유기물의 중량에 대해 3~8중량%로 혼합한다.In addition, since the hydrolysis of the protein proceeds slowly in the case of using less alkali component, it is uneconomical because it needs to be treated for a long time by applying relatively high pressure and high heat to promote hydrolysis in the pressurized heating process described below. Preferably, when using 48-51 weight% potassium etc. of purity, it mixes with 3-8 weight% with respect to the weight of organic substance.

칼륨 또는 수산화칼륨 등 강알칼리성분을 이용한 가압 가열로 가수분해시 강 산 으로 단백질을 분해하는것보다 동물성 단백질이 분해 되면서 발생하는 아미노산의 손실을 막을 수 있다Pressurized heating using strong alkalis such as potassium or potassium hydroxide can prevent the loss of amino acids caused by the breakdown of animal proteins rather than the breakdown of proteins with strong acids during hydrolysis.

그리고 상기 알칼리 성분과 더불어 첨가되는 키모트립신은 단백질분해효소로서, 단백질을 가수분해시킴과 동시에 유기물의 에스테르결합을 신속하게 가수분해한다. 따라서 이러한 키모트립신에 의해 단백질이 가수분해됨은 물론이고 에스테르화합물인 지방이 가수분해된다.In addition, the chymotrypsin added together with the alkaline component is a protease, which hydrolyzes a protein and at the same time rapidly hydrolyzes an ester bond of an organic substance. Therefore, the protein is hydrolyzed by the chymotrypsin as well as the fat, which is an ester compound.

한편, 동물성 지방은 상온에서 굳어지는데, 상기 피 가공물 중의 지방이 분해되지 않고 최종 생산물인 액상비료에 존재하게 되면, 액상비료를 토양에 분무할 때, 굳어진 지방에 의해 제대로 분무할 수 없게 되고, 액상비료를 엽면 시비시 식물의 모공을 막아 고사 시킬 수 있다.On the other hand, the animal fat is hardened at room temperature, when the fat in the workpiece is not decomposed and present in the liquid fertilizer of the final product, when spraying the liquid fertilizer into the soil, it can not be properly sprayed by the hardened fat, Fertilizer can clog the pores of the plant when fertilized.

그러나 본 발명에서는 칼륨 등과 키모트립신에 의해 지방이 가수분해되므로 상온상태에서도 용이하게 분무할 수 있어서 제품의 품질이 향상된다. 이러한 키모트립신은 그 사용량이 크게 제한 받지는 않으나 피 가공물 중량의 0.3~0.5중량% 로 혼합한다.However, in the present invention, since the fat is hydrolyzed by potassium and chymotrypsin, it can be easily sprayed even at room temperature, thereby improving product quality. Such chymotrypsin is not limited in a large amount, but is mixed at 0.3 to 0.5% by weight of the workpiece.

이와 같이 칼륨 또는 수산화칼륨등 알칼리와 키모트립신을 첨가한 다음, 가압 가열처리하는데, 전술한 바와 같이 알칼리와 키모트립신을 첨가하여 단백질과 지방을 가수분해시키므로 비교적 낮은 온도에서 단시간 처리하여도 피 가공물을 효과적으로 액상화시킬 수 있다.In this way, alkali and chymotrypsin, such as potassium or potassium hydroxide, are added, followed by pressurized heating treatment. As described above, alkali and chymotrypsin are added to hydrolyze proteins and fats. It can be liquefied effectively.

이때 바람직하게는 피 가공물을 약 120~130℃에서 2~ 4기압에서 약 30분~1시간 처리하는데, 이와 같이 가압 가열처리하면 알칼리와 키모트립신에 의해 유기물의 단백질과 지방 성분이 분해되어 액상화된다. 또 이과정에서는 있을지도 모르는 병원성세균등 미생물의 완전 사멸로 병균의 전염성을 완전 배제한다.In this case, preferably, the workpiece is treated at about 120 to 130 ° C. for about 30 minutes to 1 hour at 2 to 4 atmospheres. In this case, the pressure and heat treatment decomposes the organic and protein components of the organic matter by alkali and chymotrypsin to liquefy. . This process also completely eliminates infectious diseases by killing microorganisms such as pathogenic bacteria that may be present.

따라서 가압가열처리 후에 제조된 아미노산 액상비료는 첨가된 칼륨 등에 의해 강 알칼리성을 띠게 되므로 황산칼륨 등 산을 혼합하여 약 알칼리화시켜 토양을 알카리화시키지 않도록 하며, 사용시 적당량을 물로 희석시켜 농도를 조절 하여 엽면 시비한다.Therefore, the amino acid liquid fertilizer prepared after the pressurized heating treatment is strongly alkaline due to the added potassium. Therefore, the mixture is weakly alkalized by mixing acid such as potassium sulfate to avoid alkalizing the soil. do.

한편, 필요에 따라서는 동물의 피(血) 등을 이용해 액상의 비료를 제조시, 상기 물과 알칼리, 키모트립신 대신에 전술한 바와 같이 제조된 유기질 아미노산 액상 비료를 소정량 첨가하고 동일하게 가압 가열처리 할 수도 있다. 이와 같이 하는 경우에는 피가공물에 기 제조된 액상비료를 한 차례 혼합하면 되므로, 물과 알카리, 키모트립신을 각각 별도로 투입하여야 하는 번거로움이 없으며, 칼륨이나 키모트립신 구입에 소요되는 추가비용을 절감할 수 있다.On the other hand, if necessary, when preparing a liquid fertilizer using animal blood or the like, a predetermined amount of the organic amino acid liquid fertilizer prepared as described above in place of the water, alkali, chymotrypsin is added and pressurized heating in the same manner. You can also handle In this case, since the liquid fertilizer prepared beforehand is mixed with the processed product once, there is no need to separately input water, alkali and chymotrypsin, and further reduce the additional cost of purchasing potassium or chymotrypsin. Can be.

이상에서와 같이 본 발명에 의하면, 동물의 피(血)나 어류부산물 등을 이용하여 제조되므로 원가가 절감될 뿐만 아니라 칼륨(k)과 키모트립신을 첨가하여 단백질과 지방을 분해시킴으로써 비교적 낮은 온도에서 단시간 가압 가열하여 제조되는 새로운 유기질 아미노산 액상비료를 제공할 수 있다.이러한 본 발명에 의한 유기질비료는 천연비료이므로 화학비료와는 달리 장기간 사용하여도 토양을 황폐화시키지 않고 각종 미네랄성분을 비롯한 다양한 아미노산 성분이 함유되어 있으므로 농작물의 성장을 촉진시킬 뿐만 아니라 냉해를 방지하고 농작물의 풍미를 높이며, 농작물의 착색을 좋게 한다. 또한, 위의 원료를 이용한 성분들은 장기간 발효시키지 않아도 단시간 내에 비료화 할 수 있어서 피(血)와 어류 사체를 효과적으로 재활용할 수 있으므로, 어류 사체의 매립으로 인한 환경 오염을 방지 할 수있다.As described above, according to the present invention, since it is manufactured using animal blood or fish by-products, the cost is not only reduced, but also potassium (k) and chymotrypsin are added to decompose proteins and fats at a relatively low temperature. It is possible to provide a new organic amino acid liquid fertilizer prepared by pressurized heating for a short time. Since the organic fertilizer according to the present invention is a natural fertilizer, various amino acid components, including various mineral components, without damaging the soil even after long-term use, unlike chemical fertilizers It not only promotes the growth of crops, but also prevents cold damage, increases the flavor of crops, and improves the coloration of crops. In addition, the components using the above raw materials can be fertilized in a short time even without long-term fermentation can effectively recycle blood and fish carcasses, it is possible to prevent environmental pollution due to landfilling of fish carcasses.
