Description
본 발명은 난황유의 제조방법에 관한 것으로, 더욱 상세하게는 난황을 반숙 건조하여 작업시간을 최소화함과 더불어 입자상으로 분쇄한 후 이단 착유하여 착유과정의 부하를 최소화하고 난황유의 추출량을 증대시킬 수 있도록 함을 목적으로 한 것이다.The present invention relates to a method for producing yolk oil, and more particularly, to minimize the working time by semi-dried yolk, while pulverizing into granules and then double-milking to minimize the load of the milking process and increase the extraction amount of yolk oil. The purpose is to.
일반적으로, 난황유는 계란의 노른자로부터 추출한 것으로, 인체에 유익한 레시친이 다량 함유되어 있는 것이다.In general, egg yolk oil is extracted from egg yolk and contains a large amount of lecithin, which is beneficial to the human body.
상기한 바와 같이 레시친이 다량 함유되어 있는 난황유의 추출방법으로는 오래 전부터 전통적으로 사용되던 소초법과, 별도의 용매를 사용하여 추출하는 용매추출법이 사용되었으나, 상기한 바와 같은 난황유의 추출방법은 난황유의 색이 변색되고 용매의 추출을 위한 복잡한 공정을 거쳐야하는 등의 문제점이 있었다.As described above, as a method of extracting yolk oil containing a large amount of lecithin, a cowweed method, which has been used for a long time, and a solvent extraction method using a separate solvent, have been used. There have been problems such as discoloration and a complicated process for extraction of the solvent.
이에, 계란으로부터 난황을 분리하는 할란공정과, 착유시 난황유의 원활한 착유를 위하여 효소를 첨가하여 반응시키는 효소처리공정과, 상기 할란공정에서 분리된 난황을 분무건조와 가열처리를 통하여 건조하는 건조공정과, 상기 건조공정에서 건조된 난황을 분말상태로 분쇄하는 분쇄공정과, 상기 분쇄공정에서 분말상태로 분쇄된 난황가루를 착유기로 착유하는 착유공정으로 이루어진 난황유착유방법을 통하여 난황유를 추출하였다.Thus, a process for separating egg yolk from eggs, an enzyme treatment step for adding enzymes for smooth milking of egg yolk milk during milking, and a drying step for drying the egg yolk separated in the egg process by spray drying and heat treatment Egg yolk milk was extracted through a yolk milking method comprising a milking step of pulverizing the yolk dried in the drying step into a powder state and a milking step of milking the yolk powder pulverized in the powder state in the grinding step.
그러나, 상기한 바와 같은 종래의 난황유 추출방법은 추출공정에서 난황유의 원활한 추출을 위한 효소처리공정을 거쳐야 하므로 그 작업시간에 상단한 시간이 소요되고, 분쇄된 난황이 분말상태로 분쇄되어 착유기의 호퍼에서 서로 뭉쳐져 착유기로의 원활한 공급이 이루어지지 않으며, 착유스크류에 의한 착압과정에 있어 분말상태의 난황이 스크류와의 사이에서 미끄럼이 발생하여 착압이 원활하게 이루어지지 않아 착유효율이 저하되는 등의 문제점이 있었다.However, the conventional yolk oil extraction method as described above has to go through the enzymatic treatment process for the smooth extraction of yolk oil in the extraction process, so it takes a long time in the working time, the pulverized yolk is pulverized into a powder state hopper of the milking machine In the process of pressing by the milking screw, the yolk in the powder state slips between the screw and the milking efficiency is not made smoothly. There was this.
또한, 상기한 바와 같이 분말상태의 난황이 원활하게 착압되지 않아 스크류의 크기를 길게 형성하므로서 착유기에 과부하가 걸려 수명이 단축되는 등의 문제점이 있었다.In addition, as described above, there is a problem that the yolk in the powder state is not smoothly pressed and the size of the screw is formed to be long, thereby overloading the milking machine and shortening the lifespan.
이에, 본 발명은 상술한 문제점을 해결하기 위하여 창출한 것으로, 할란공정을 통하여 분리된 난황을 반숙하고, 이를 건조한 후 입자상으로 분쇄하며, 분쇄된 난황을 재차 건조하고, 이를 이단 착유하여 난황으로부터 난황유를 추출할 수 있게 한 것이다.Thus, the present invention was created to solve the above-mentioned problems, the ripened egg yolk separated through the harlaning process, dried and pulverized into granular, dried crushed egg yolk again, milking it two-stage from yolk yolk To be able to extract.

이하, 본 발명에 의한 난황유의 제조과정을 설명하면 다음과 같다.Hereinafter, the manufacturing process of the egg yolk oil according to the present invention will be described.
상기한 바와 같이 할란공정(1)과 반숙공정(2), 1 차 건조공정(3), 분쇄공정(4), 2 차 건조공정(5), 1 차 착유공정(6), 분쇄이송공정(7), 2 차 착유공정(8) 및 불순불분리공정(9)으로 이루어진 본 발명에 의하여 난황유를 추출하고자할 경우에는 우선 할란공정을 통하여 계란으로부터 노른자를 분리하고, 상기 할란공정에서 분리된 노른자 즉 난황을 반숙공정(2)을 통하여 70~100℃의 온도로 3~4 분동안 가열하여 반숙한다.As described above, the harlan process (1) and the semi-preparation process (2), the primary drying process (3), the pulverization process (4), the secondary drying process (5), the primary milking process (6), and the grinding conveyance process ( 7), in the case of extracting egg yolk oil according to the present invention comprising the secondary milking step (8) and the impurity separation step (9), first, the yolk is separated from the egg through the harlaning step, and the yolk separated in the harlaning step In other words, the yolk is heated by heating at a temperature of 70-100 ° C. for 3-4 minutes through the half-boiling process (2).
그리고, 상기 반숙공정(2)을 통하여 반숙된 난황을 1 차 건조공정(3)을 통하여 수분함량이 5% 이하가 되게 60~80℃의 온도로 가열 건조하고, 상기 1 차 건조공정(3)에서 수분함량이 5% 이하로 건조된 난황을 분쇄공정(4)에서 좁쌀 내지 쌀알 크기의 입자상태로 분쇄하며, 상기 분쇄공정(4)을 통하여 좁쌀 내지 쌀알 크기의 입자상태로 분쇄된 난황은 2 차 건조공정(5)을 통하여 수분함량이 2% 이하가 되게 160~180℃의 온도로 가열 건조하여 난황유의 착유를 위한 준비를 완료한다.Then, the dried yolk, which has been subjected to the half-boiling process (2), is heated and dried at a temperature of 60 to 80 ° C. such that the moisture content is 5% or less through the primary drying process (3), and the primary drying process (3). Egg yolk dried at 5% or less in water content is pulverized to granules of rice to grain size in the crushing process (4), and yolk crushed to grains of millet to rice grain size in the crushing process (4) is 2 Through the drying step (5) to heat the moisture content to 160 ~ 180 ℃ to 2% or less to complete the preparation for milking the yolk yolk.
상기한 바와 같은 공정을 통하여 좁쌀 내지 쌀알 크기의 입자상태로 분쇄 건조된 난황을 1 차 착유공정(60)의 스크류형 착유기(60) 호퍼(61)에 투입하고 160~180℃의 온도로 가열하면서 30~40초 동안 착유하여 난황유를 추출한다. 이때, 호퍼(61)를 통하여 투입된 난황이 입자상태이어서 서로 달라붙지 않고 부드럽게 유동되며 스크류에의 의한 착압도 용이하게 이루어지고 난황으로부터 약 8~10%의 난황유가 추출되게 되는 것이다.The yolk pulverized and dried in the form of granules to the size of grains of rice through the process as described above is introduced into the hopper 61 of the screw-type milking machine 60 of the first milking process 60 and heated to a temperature of 160 ~ 180 ℃ Milk for 30-40 seconds to extract yolk oil. At this time, the yolk introduced through the hopper 61 is in the form of particles, so that they smoothly flow without sticking to each other, and the pressure is easily made by the screw, and about 8 to 10% of the yolk oil is extracted from the yolk.
또한, 상기 1 차 착유공정(6)에서 8~10%의 난황유가 착유되어 배출되는 꽈배기 상태의 난황묵편을 분쇄이송공정(7)을 통하여 0.5~2㎝ 크기로 분쇄 이송하는데, 이때, 스크류콘베어(70) 브레이드의 높이를 0.5~2㎝로 형성하므로서 연속하여 꽈배기형으로 배출되는 난황묵편이 2 차 착유공정(8)의 호퍼(81)에 용이하게 공급될 수 있게 분쇄되는 것이다.In addition, in the primary milking process (6), 8 ~ 10% of the yolk oil is discharged by milking and discharged in the pretzel state yolk jelly pieces through a grinding conveying process (7) to the size of 0.5 ~ 2cm, screw conveyor (70) By forming the height of the braid to 0.5 ~ 2cm, the yolk yolk pieces continuously discharged in a pretzel type are pulverized so that they can be easily supplied to the hopper 81 of the secondary milking process (8).
그리고, 상기 분쇄이송공정(7)을 통하여 0.5~2㎝ 크기로 분쇄 이송된 난황묵편은 2 차 착유공정(8)의 스크류형 착유기(60)에서 150~180℃의 온도로 가열되면서 2 차 착유되게 되는데, 이때 난황으로부터 15~20%의 난황유가 추출되게 되는 것이다.Then, the yolk yolk pieces crushed and conveyed to a size of 0.5 ~ 2 ㎝ through the crushing conveying process (7) is heated to a temperature of 150 ~ 180 ℃ in the screw-type milking machine (60) of the secondary milking process (8) At this time, 15 to 20% of egg yolk oil is extracted from egg yolk.
한편, 상기 1 , 2 차 착유공정(60,80)에서 착유되어 집유통(62,82)에 집유되는 난황유는 6cc/㎠.sec의 통기도를 갖는 여과포(91)에 의하여 일차적으로 불순물이 걸러져서 집유탱크를 거쳐 원유저장탱크(93)에 냉각 저장되거나 또는 2cc/㎠.sec의 통기도를 갖는 필터프레스(92)에 의하여 불순물은 최종적으로 깨끗이 완벽하게 제거될 수 있는 것이다.Meanwhile, egg yolk oil, which is milked in the primary and secondary milking processes (60, 80) and collected in the collecting tanks (62, 82), is first filtered out by the filter cloth (91) having an air permeability of 6 cc / cm 2 .sec. Impurities may be finally completely and completely removed by the filter press 92 having a ventilation of 2cc / cm 2 sec or stored in the crude oil storage tank 93 via a collecting tank.
이상과 같이 불순물이 분리된 난황유는 완제품저장탱크(94)에서 냉각 저장되는 것이다.The yolk oil from which impurities are separated as described above is cooled and stored in the finished product storage tank 94.
따라서, 본 발명은 난황을 반숙 가공하여 건조하므로 작업시간이 단축되고, 분쇄공정을 통하여 입자상으로 분쇄공급하므로서 착유공정에 있어서 유동성과 착유성이 향상되는 한편, 이단 착유를 통하여 난황유를 추출하므로 난황유의 추출량이 극대화되며, 착유기의 과부하가 방지되는 매우 유용한 것이다.Therefore, in the present invention, the working time is shortened because the yolk is semi-processed and dried, the fluidity and milking performance is improved in the milking process by pulverizing and supplying the granular powder through the grinding process, and the yolk oil is extracted through two-stage milking. The extraction amount is maximized and the overload of the milking machine is very useful.
