Description

도축혈액을 이용한 액상비료 제조 방법{Method for manufacturing liquefied fertilizer using butchery blood}TECHNICAL FIELD The present invention relates to a method for manufacturing liquid fertilizer using slaughter blood,

본 발명은 가축을 도축할 때 발생되는 도축 혈액을 이용하여 액상비료를 제조하는 방법에 관한 것이다.The present invention relates to a method for producing a liquid fertilizer using slaughter blood generated when slaughtering livestock.

일반적으로, 가축을 도축하는 도축장에선 도축 혈액[축혈(畜血)] 가죽, 분뇨, 오수 등의 폐기물이 다량 발생하고 있다. 여기서 축혈(선지)은 일부가 식용으로 사용되고 있으나 대부분이 폐기물로 처리되고 있으나 혈액에 COD 및 BOD가 높아 폐수처리 방법으론 한계가 있다. 해서 도축장에서 발생하는 다량의 축혈을 삶아서 폐기물로 매립이나 소각에 의존하여 처리되고 있다. 최근 들어 폐기물로 매립하는 대신에 액체 비료를 만들기 위한 시도가 이루어지고 있다. 대한민국 등록특허공보 제10-1100850호 등을 참조할 수 있다. 그러나 기존 비료 제조 방법으로는 도축 혈액에 대한 발효에만 그칠 뿐, 그렇게 생산된 액상 비료에 세균이 번식하고 부패 되어 악취로 인해 농민들의 사용이 어렵다.Generally, slaughterhouses that slaughter livestock have a large amount of wastes such as slaughter blood, leathers, manure, and sewage. Here, some of them are used for edible purposes, but most of them are treated as waste, but the method of treating wastewater is limited due to high COD and BOD in blood. It is processed by relying on waste landfill or incineration by boiling a large amount of sausage from the slaughterhouse. In recent years, attempts have been made to make liquid fertilizers instead of landfilled. Korean Patent Registration No. 10-1100850, and the like. However, conventional methods of producing fertilizer are only fermentation for slaughter blood, and it is difficult for farmers to use the smell because the bacteria grow and corrode in the liquid fertilizer produced.

본 발명의 목적은, 응고된 도축혈액을 미립자로 분쇄하여도 응고되기 이전의 혈액으로 돌아오지 않는다. 해서 미립자 된 도축혈액의 발효촉진과 발효의 균일성을 높이고 발효된 액상 비료 내에서 세균이 번식하여 상기 액상 비료가 부패하여 사용하기에 부적합해지는 것을 막을 수 있는, 도축 혈액을 이용한 액상 비료 제조 방법을 제공하는 것이다.It is an object of the present invention to provide a method for producing a microorganism which does not return to the blood before coagulation even when the coagulated slaughter blood is pulverized into fine particles. Thereby increasing the uniformity of fermentation of the slaughtered blood of microparticles and improving the uniformity of fermentation and preventing bacteria from propagating in the fermented liquid fertilizer to prevent the liquid fertilizer from being spoiled and unsuitable for use, .

상기한 과제를 실현하기 위한 본 발명의 일 실시예와 관련된 도축혈액을 이용한 액상 비료 제조 방법은, 응고 된 도축 혈액을 분쇄하여 물 20~100중량%와 구연산을 첨가하고 혼합물의 온도가 50~65℃를 상승하면 단백질 분해 효소를 넣고 도축혈액과 물과 효소의 혼합물의 온도를 50℃ 내지65℃ 범위 내로 유지하고 발효의 균일성과 발효의 효율을 높이기 위해 교반기 및 에어로 4~6시간의 교반 과정을 거치고 발효가 완료되면 발효혈액 내에 있는 세균 및 더 이상 발효되지 않도록 천연 방부제인 구연산 및 솔빈산을 첨가하여 액상 비료를 생산하는 단계를 포함한다.In order to accomplish the above object, there is provided a method for producing liquid fertilizer using slaughter blood according to one embodiment of the present invention, which comprises pulverizing solidified slaughter blood, adding 20 to 100% by weight of water and citric acid, When the temperature is elevated, the protease is added, and the mixture is maintained at a temperature of 50 to 65 ° C for a mixture of slaughter blood, water and enzyme. To increase the uniformity of the fermentation and the efficiency of fermentation, a stirrer and aeration are performed for 4 to 6 hours And after the fermentation is completed, the bacteria in the fermentation blood and citric acid and sorbic acid, which are natural preservatives, are added to prevent further fermentation to produce liquid fertilizer.

상기와 같이 구성되는 본 발명에 관련된 도축혈액을 이용한 액상 비료 제조 방법에 의하면, 도축 혈액으로부터 제조된 액상 비료 내에서 세균이 번식하여 상기 액상 비료가 부패하며 냄새가 나는 것을 막을 수 있다.According to the method for producing liquid fertilizer using the slaughter blood according to the present invention, bacterial propagation in the liquid fertilizer produced from slaughter blood can prevent the liquid fertilizer from being corrupted and smelling.

또한, 발효를 높이기 위해 물과 효소를 넣고 교반하고 효소는 혈액 중에 포함된 단백질을 분해함에 있어 리쿠아나제 또는 브로멜라인은 종래의 다른 프로티아나제를 사용하는 경우 보다 적은 양으로써 발효 시간도 대략 절반으로 단축할 수 있게 된다. 이는 비료 제조 설비의 운영 효율을 높여서, 비료 제조 가격을 낮출 수 있게 하는 점에서 유용하다.Further, in order to increase the fermentation, water and enzyme are added and stirred, and the enzyme decomposes the protein contained in blood. Ricuanase or bromelain has a smaller fermentation time than that of other conventional proteinases It is possible to shorten it by half. This is useful in increasing the operating efficiency of the fertilizer manufacturing facility, thereby lowering the fertilizer production cost.

도 1은 본 발명의 일 실시예에 따른 도축혈액을 이용한 액상 비료 제조 방법을 설명하기 위한 순서도이다.FIG. 1 is a flowchart illustrating a method of manufacturing liquid fertilizer using slaughter blood according to an embodiment of the present invention. Referring to FIG.

본 발명의 바람직한 실시 예에 따른 도축혈액을 이용한 액상 비료 제조 방법에 대하여 첨부한 도면을 참조하여 상세히 설명한다. 본 명세서에서는 서로 다른 실시예라도 동일 유사한 구성에 대해서는 동일 유사한 참조번호를 부여하고, 그 설명은 처음 설명으로 갈음한다.A method for manufacturing a liquid fertilizer using slaughter blood according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. In the present specification, the same reference numerals are assigned to the same components in different embodiments, and the description thereof is replaced with the first explanation.

도 1은 본 발명의 일 실시예에 따른 도축 혈액을 이용한 액상 비료 제조 방법을 설명하기 위한 순서도이다.FIG. 1 is a flowchart illustrating a method of manufacturing liquid fertilizer using slaughter blood according to an embodiment of the present invention. Referring to FIG.

본 도면을 참조하면, 액상 비료를 제조하기 위한 원료로서 도축혈액이 준비된다(S1). 도축혈액은 도축장에서 소, 돼지, 가금류 등을 도축하는 과정에서 발생되는 부산물이다. 이러한 도축혈액은 수집되어, 냉장 보관(S2) 한다.Referring to this figure, slaughter blood is prepared as a raw material for producing liquid fertilizer (S1). Slaughter blood is a by-product of slaughtering cattle, pigs, and poultry in slaughterhouses. The slaughter blood is collected and stored in the refrigerator (S2).

냉장 보관된 도축 혈액을 분쇄(S3)하고 미립자 된 혈액에 심줄이 있어 여과(S4) 한다. 도축 혈액은 분쇄 및 여과되어 미립자가 된다. 도축 혈액은 미립자 될 수록 다음 단계(S5)에서 발효가 원활해진다.The refrigerated slaughter blood is pulverized (S3), and there is a tendon in the particulate blood (S4). The slaughter blood is pulverized and filtered to become a particulate. As the slaughter blood becomes fine particles, the fermentation becomes smooth in the next step (S5).

도축혈액을 발효탱크(S5)로 이송하고 발효성과 효율을 높이기 위해 물 또는 탱크의 세척수 20~100중량%과 구연산를 첨가하여 도축혈액과 물과 구연산이 혼합 되도록 교반하면서 발효탱크내 온도가 50℃ 내지65℃가 되도록 가열한다. 상기 혼합물의 온도가 50℃ 내지65℃가 되면 발효효소를 첨가하고 4~6 시간을 교반하면서 발효 시킨다. 상기 효소로는 리쿠아나제(Liquanase) 또는 브로메타인이 사용될 수 있다. 상기 리쿠아나제와 브로메타인은 역가가 높아 도축 혈액을 발효시키는 능력이 우수하다. 구체적으로, 상기 효소는 25℃에서 pH가 5.60이고, 점도는 20.1 CPS이며, 생균수(Viable count)는 100/G인 것일 수 있다. 상기 효소는 상기 미립자 된 도축 혈액의 중량 대비 0.25 중량% 내지 0.5 중량% 범위 내의 양으로 첨가될 수 있다. 상기 효소의 양이 0.25 중량% 미만이면, 도축 혈액에 대한 발효 시간이 길어지는 문제가 있다. 또한, 상기 효소의 양이 0.5 중량%를 초과해도, 위 발효 속도가 의미 있게 증가 되지는 않는다.The slaughter blood is transferred to the fermentation tank (S5), 20 to 100% by weight of washing water of water or tank is added to the fermentation tank (S5), and citric acid is added to the slaughter blood, 65 C < / RTI > When the temperature of the mixture reaches 50 ° C to 65 ° C, the fermentation enzyme is added and fermented for 4 to 6 hours with stirring. As the enzyme, liquanase or bromethine may be used. The above-mentioned ricuanazides and bromethanes have high potency and are excellent in the ability to ferment slaughter blood. Specifically, the enzyme may have a pH of 5.60 at 25 ° C, a viscosity of 20.1 CPS, and a viable count of 100 / G. The enzyme may be added in an amount within the range of 0.25% by weight to 0.5% by weight based on the weight of the microparticulated slaughter blood. If the amount of the enzyme is less than 0.25% by weight, the fermentation time for the slaughter blood becomes long. Furthermore, even if the amount of the enzyme exceeds 0.5% by weight, the above fermentation rate is not significantly increased.

상기 리쿠아나제 및 브로메타인을 이용한 발효에 있어서, 상기 발효탱크 내에 수용된 도축혈액과 효소의 혼합물은 50℃ 내지 65℃ 범위 내로 유지되어야 한다. 상기 혼합물의 온도가 50℃ 미만이면 정상적인 발효가 어렵고, 65℃를 초과하면 발효 시간은 단축될 수 있으나 고온으로 인해 미생물이 죽으므로 발효효과가 줄어들어 단백질 분해가 되지 않아 아미노산으로 전환율이 적어 아마노산 함유율이 낮아진다. 본 발명자는 시험을 통하여, 리쿠아나제 및 브로메타인의 효소로 사용하는 경우에 상기 혼합물와 온도를 55℃ 내지 56℃ 범위 내로 유지하는 것이 발효 성능을 높이고 발효 시간을 단축하는데 유용함을 파악하였다. 상기 발효탱크의 온도를 유지하기 위해서, 상기 발효탱크의 몸체는 삼중탱크로 제작하여 중피와 내피 사이에 온수를 공급하여 발효탱크에 열을 공급하고 열 공급 방법으로는 보일러를 거치 한다.In the fermentation using the above-mentioned ricinase and bromethine, the mixture of the slaughter blood and the enzyme contained in the fermentation tank should be maintained within the range of 50 ° C to 65 ° C. If the temperature of the mixture is less than 50 캜, normal fermentation is difficult. If the temperature exceeds 65 캜, the fermentation time may be shortened. However, since the microorganisms die due to high temperature, the fermentation effect is reduced, . The inventors have found through testing that it is useful to maintain fermentation performance and to shorten the fermentation time by maintaining the temperature of the above mixture within the range of 55 ° C to 56 ° C when it is used as an enzyme of ricinase and bromethine. In order to maintain the temperature of the fermentation tank, the body of the fermentation tank is made of a triple tank, and hot water is supplied between the skin and the inner skin to supply heat to the fermentation tank.

발효를 효과적으로 수행하기 위하여 상기 발효탱크에 미립자 된 도축 혈액과 물 및 효소를 한 번에 다 넣지 않고 균주의 활성을 위해 물 또는 탱크 세적수를 상온에서 활성 시킨 후 도축혈액을 두세 번 나누어서 넣는 방법을 사용할 수 있다. 예를 들어, 도축 혈액의 전체 양 중 절반을 먼저 상기 발효탱크에 넣고 교반한 후에, 도축혈액의 전체 양 중 나머지 절반을 상기 발효탱크에 추가로 넣고서 전체적으로 교반할 수 있다. 그에 의해 도축 혈액 전체 중 일부에 대한 먼저 진행하는 이유는 발효성 균주를 증식하는 것이며, 해서 부분적으로 발효가 진행된 도축혈액에 나머지 새로운 도축 혈액이 추가되어 함께 발효되게 되는 것이다.In order to effectively perform the fermentation, a method of activating the water or the tank water in the fermentation tank at room temperature for the activity of the strain without feeding the slaughtered blood, the water and the enzyme all at once, and then slaughtering the blood two or three times Can be used. For example, after half of the total amount of slaughter blood is first placed in the fermentation tank and stirred, the remaining half of the total amount of slaughter blood may be further added to the fermentation tank and stirred as a whole. Therefore, the reason for first proceeding to some of the whole slaughter blood is to proliferate a fermentation strain, so that a new slaughter blood is partially added to the slaughtered blood that has been partially fermented and fermented together.

발효된 도축혈액내 유리 아미노산 함량을 높이기 방법으로 액정상 펩타이드 나노 구조체로 전환을 위해 초음파 또는 진공농축기를 설치하여 유리 아미노산 함량을 높인다.In order to increase the free amino acid content in fermented slaughtered blood, an ultrasound or vacuum concentrator is installed to convert it into a liquid crystal peptide nanostructure, thereby increasing free amino acid content.

발효된 도축혈액은 아미노산을 함유한 상태로서 발효탱크(S5) 또는 완제품 탱크(S7)에서 구연산 및 솔빈산을 첨가하므로 살균 된다.The fermented slaughter blood contains amino acids and is sterilized by adding citric acid and sorbic acid in the fermentation tank (S5) or the finished product tank (S7).

이러한 살균에 의해서, 아미노산을 함유하는 액상 비료는 살균 처리가 된다. 상기 살균 처리는 세균이 살아 있거나 미발효 되어 잔존된 성분이 발효되면서 액상 비료가 부패되고 심한 냄새를 제거하고 예방하기 위함이다.By such sterilization, the liquid fertilizer containing the amino acid is sterilized. The sterilization treatment is to sterilize the liquid fertilizer and to remove and prevent the bad smell when the bacteria are alive or not fermented and the remaining components are fermented.

상기 발효된 액상비료에 2차로 천연 방부제를 첨가하여서 더 이상의 발효를 억제함으로써 포장 후에도 발효되면서 가스가 발생되어 액상 비료가 든 병이 부풀어 오르고 냄새가 나는 것을 방지한다. 냄새가 나지 않아 소비자가 취급하기 원활하며 상기 액상 비료가 뿌려진 채소는 발육을 촉진시키고 과일은 성장과 과일의 당도를 높여주는 역할을 한다.By adding a second natural preservative to the fermented liquid fertilizer, the fermentation is further inhibited by further inhibiting the fermentation, so that gas is generated while being packaged to prevent the bottle with liquid fertilizer from swelling and smell. The smell does not occur so that the consumer is able to handle it smoothly. The liquid fertilizer is sprayed with vegetables to promote the growth, and the fruit grows and increases the sugar content of the fruit.
