두부제조용 대두건조분말 및 그 제조방법{A DRIED SOYBEAN POWDER FOR MANUFACTURING BEAN CURD AND THE METHOD FOR MANUFACTURING}Soybean dry powder for tofu production and its manufacturing method {A DRIED SOYBEAN POWDER FOR MANUFACTURING BEAN CURD AND THE METHOD FOR MANUFACTURING}

본 발명은 두부제조용 생콩을 이용한 건조상태의 대두건조분말 및 상기 대두건조분말에 첨가제를 첨가한 대두건조분말과 그 제조방법에 관한 것으로서, 더욱더 상세하게는 종래의 두부제조방법에 있어 생콩을 물속에 침수하고 물과 함께 분쇄하여 두유를 제조하고 두유에 응고제(간수)를 넣어 두부를 생산하는 과정에서 생콩을 침수하고 물과 함께 분쇄하여 두유를 제조하고 비지를 걸러내는 과정 없이 제조된 대두건조분말과 그 제조방법에 관한 것으로서 대량생산시 제조공정이 용이할 뿐만 아니라 생산시간을 단축하고 일반 수요자들이 가정에서 손쉽게 상기 대두건조분말을 이용하여 두부를 만들어 먹을 수 있도록 하기 위한 것이다. 또한 본 발명은 상기 대두건조분말 제조시 쑥, 깨 및 땅콩 등과 같은 첨가제를 첨가하여 분쇄하므로써 일반 수요자의 연령이나 취양에 따라 다양한 맛을 구비할 수 있는 대두건조분말을 제조할 수 있다.The present invention relates to a dry soybean dry powder using raw soybeans for tofu production and soybean dry powder to which an additive is added to the soybean dry powder, and a method of manufacturing the same. More specifically, in the conventional tofu manufacturing method, raw soybeans are placed in water. Soybean dried powder prepared by immersing raw beans and crushing with water to make soy milk and sieving sewage in the process of immersing and crushing with water to make soy milk and adding soy milk with coagulant (salt water). The present invention relates to a manufacturing method, which is not only to facilitate the manufacturing process during mass production, but also to shorten the production time and allow consumers to easily make and eat tofu using the soy dry powder at home. In addition, the present invention can prepare a soybean dried powder that can have a variety of tastes depending on the age or taste of the general consumer by adding and grinding additives such as mugwort, sesame seeds and peanuts during the manufacturing of the soybean dried powder.

종래의 두부제조공정에 있어서는 일반적으로 선별된 두부제조용 콩을 세척하는 세척공정과; 8시간 동안 침수하여 콩을 불리는 침수공정과; 상기 침수된 콩을 맷돌에 가는 분쇄공정과; 상기 분쇄공정을 거친 곱게 갈려진 콩에 물을 가하여 100 ℃ 정도 까지 가열하여 여과법을 이용하여 비지와 콩물(두유)을 분리하는 가공분리공정; 및 상기 분리된 두유에 응고제를 넣어 두부를 제조하는 두부생산공정으로 이루어져 있다. 이때 상기 가공분리공정에 있어서는 100 ℃까지 온도가 올라가는 과정에서 세균이나 효소가 작용하지 않도록 짧은 시간 내에 100 ℃로 끓이고 높은 온도에서 단백질의 열 변성이 일어나지 않도록 빨리 꺼내어 여과법을 이용하여 비지와 두유를 분리하는 것이 바람직하다.In the conventional tofu production process, the washing process for washing the generally selected tofu production soybeans; Immersion process called soybean by immersion for 8 hours; Grinding the soaked beans into millstone; Process separation step of separating water and soybeans (soy milk) using a filtration method by adding water to the finely ground soybean through the grinding step and heating up to about 100 ℃; And a tofu production process for preparing a tofu by putting a coagulant into the separated soymilk. At this time, in the process separation process, boils to 100 ℃ within a short time so that bacteria or enzymes do not work in the process of increasing the temperature up to 100 ℃ and quickly removes soy milk and soy milk using filtration to remove the heat denaturation of protein at high temperature. It is desirable to.

그러나, 상기와 같은 두부제조공정은 순차적으로 세척공정; 침수공정; 분쇄공정; 가공분리공정; 두부생산공정을 거쳐야 완제품인 두부를 생산할 수 있어 대량생산체제하에서는 두부제조시간이 많이 소요되어 적절하지 못하며, 그 공정 또한 복잡하여 비효율적이다는 문제점이 있었다.However, the tofu manufacturing process as described above is sequentially washed; Immersion process; Grinding process; Processing separation process; Tofu, which is a finished product, can only be produced through the tofu production process, so it is not appropriate due to the time required for manufacturing tofu under a mass production system, and the process is also complicated and inefficient.

특히, 상기 분쇄공정에 있어서는 콩이 열을 받게되면, 생산하고자 하는 두부의 맛이 떨어질 뿐만 아니라 수율도 낮게되는 문제점이 있었다. 따라서, 이를 해결하기 위해 물을 투입하여 냉각하고자 하는 노력이 있었으며, 이러한 공정은 정확한 수치 보다는 경험칙에 의거 그 물의 흐름을 조정하기 때문에 대량생산체제하에서 두부를 제조함에 있어는 적절하지 못하는 방법인 점이 또한 문제가 되었다. 그리고 상기 분쇄공정에 의해 제조된 콩의 입자는 일반적으로 8~15 ㎛ 정도이어서 완제품인 두부의 맛이 둔탁하고 부드럽지 못하게 하는 원인이기도 하였다.In particular, in the grinding process, when the beans are subjected to heat, not only the taste of tofu to be produced is reduced but also the yield is low. Therefore, to solve this problem, efforts have been made to cool water by adding water, and this process is not suitable for manufacturing tofu under a mass production system because the water flow is adjusted based on empirical rules rather than accurate values. It was a problem. In addition, the grains of the soybean prepared by the grinding process are generally about 8 to 15 μm, which is a cause of the taste of the tofu, which is a finished product, to be dull and soft.

또한, 상기 가공분리공정에 있어서 발생하는 비지는 단백질의 함량이 15~20 % 정도로 높아 초기에는 서민들의 일용식으로 널리 사용되었으나 경제적 안정이 회복된 이후로부터 현재까지는 널리 쓰여지지 못하고 폐기물로서 처리되고 있으며, 이때, 비지의 발생량은 수입콩으로 수분 85 %의 두부를 만들었을 때 수분을 함유한 콩 무게에 대비해 1.2 배 이상 정도나 되어 실제 두부수율이 낮아질 수 밖에 없는 문제점을 안고 있다.In addition, in the process and separation process, the busy business has a high protein content of about 15 to 20%, which was widely used as a daily food for the common people, but since the economic stability has been restored, it has not been widely used until now and is treated as waste. In this case, the amount of bean curd is about 1.2 times more than the weight of the soy-containing soybeans when the tofu with 85% moisture is made from imported soybeans.

한편, 이러한 두부제조공정때문에 일반 수요자들은 가정에서 두부를 만들기가 어려워 두부라는 상품이 널리 가계에서 흔히 찾을 수 있는 식품으로는 부적합하였고 또한 일반 수요자들도 각종 성인병에 유용한 콩의 중요성에 대해 인지하면서도 흔히 접하기 어려운 식품으로 전락할 수 밖에 없었다.On the other hand, it is difficult for general consumers to make tofu at home because of this tofu manufacturing process, so the product called tofu is not suitable as a food commonly found in households, and general consumers are also aware of the importance of beans useful for various adult diseases. There was no choice but to fall into food that was difficult to access.

본 발명은 이와 같은 문제점을 해결하기 위해 안출한 것으로, 두부 제조시 두부제조 공정을 간단히하여 대량생산체제하 적합한 두부를 제조하고자 하는 방법을 제공하고 더우기 두부수율을 높일 수 있도록 함과 아울러 가정에서 손쉽게 일반 수요자들이 두부를 만들어 먹을 수 있도록 하기 위한 대두건조분말을 제공하는 것을 그 목적으로 한다. 또한, 상기 대두건조분말에 쑥, 깨, 땅콩 등을 첨가하여 다양한 맛을 구비한 두부를 상용화 할 수 있도록 한 것이다.The present invention has been made to solve the above problems, to simplify the tofu manufacturing process in the production of tofu to provide a method for producing a suitable tofu under a mass production system, and to further increase the yield of tofu and at home easily Its purpose is to provide soybean dry powder for consumers to make and eat tofu. In addition, by adding mugwort, sesame seeds, peanuts, etc. to the soybean dried powder tofu to commercialize a variety of flavors.

따라서, 본 발명은 대량생산체제 및 널리 상용화될 수 있도록 하기 위해 미세한 대두분말을 제조하고, 이를 이용하여 손쉽게 두부를 제조하기 위한 것으로서 종래에 두부제조공정 중 생콩을 선별하는 과정과 이렇게 선별된 콩을 세척하는 과정과 8시간 정도 침수하여 콩을 불리는 번로로운 과정 없이 건조상태에 있는 콩을 바로 메시콘베어가 장착된 열풍 건조 살균기에 통과시켜 살균 및 이물질을 제거할 수 있어 두부제조공정이 단축되어 대량생산이 매우 용이하게 하였을 뿐 아니라 그 생산효율도 증대시킬 수 있는 것이다.Therefore, the present invention is to produce a fine soybean powder in order to be mass-produced and widely commercialized, and to easily prepare tofu using the same process for selecting raw soybeans during the tofu manufacturing process and the selected soybeans. Soybeans are washed for 8 hours and soaked in soybeans without passing through so-called soybeans. The soybeans can be directly passed through a hot air drying sterilizer equipped with a mesh conveyor to remove sterilization and foreign substances. This not only makes it very easy, but also increases the production efficiency.

또한, 종래에는 대두를 건조상태(생콩상태)에서 미세하게 분쇄할 수 있는 방법이 없어 물과 함께 일정시간 침수된 생콩을 맷돌 등의 분쇄기에 의하여 분쇄하면서 물을 투입하여야 하는데 이러한 두부제조방법 빠르고 미세하고 분쇄하기 어려운 점이 있었으며, 많은 양의 비지를 걸러 내야하기 때문에 두부수율 또한 떨어지게 되는 문제점을 해결하기 위해 본 발명은 도1.에서 제시된 건조원료분쇄장치 등과 같은 분쇄장치를 통하여 생콩을 분쇄하는데 상기 분쇄공정 전에 먼저 생콩을 액화질소가스에 의해 동결시켜 분쇄시 열발생을 억제하므로써 콩의 변질을 막을 수 있도록 하고 또한 동결된 콩을 사용함으로서 분쇄시 콩의 입자가 2~5 ㎛ 정도로 동결분쇄가 가능하도록 하여 상기에서 상술한 종래의 두부제조공정상 분쇄공정에서 발생하는 문제점을 해결할 수 있었다.In addition, conventionally, there is no method for finely crushing soybeans in a dry state (raw bean state), so water should be added while grinding fresh soaked beans with water by a grinder such as a millstone. In order to solve the problem that the tofu yield is also lowered because it has to filter out a large amount of busy paper, the present invention is to crush the raw beans through a grinding device such as a dry raw material grinding device shown in Figure 1. Before the process, the raw beans are frozen by liquefied nitrogen gas to prevent heat generation during grinding to prevent the deterioration of the beans. Also, by using frozen beans, the beans can be freeze-pulverized to 2 ~ 5 ㎛ during grinding. To solve the problems occurring in the grinding process in the conventional tofu manufacturing process described above I was able to connect.

또한, 상기 동결분쇄공정을 거친 두부는 종래의 둔탁하고 부드럽지 못한 맛을 내는 두부와 달리 연하고 부드러워 입맛을 더 높여 줄 뿐만 아니라 콩의 인체에 대한 유용성이 널리 알려진 사실로부터 종래에 두부가 일상생활에 쓰여지는 용도에 한정되지 않고 널리 일반 식품으로 상용화되어지는 것에도 부합된다 할 것이다.In addition, the tofu, which has undergone the freeze-grinding process, is soft and soft, unlike the conventional tofu, which has a dull and soft taste, not only increases the taste, but also the fact that soybeans have been widely used in humans in the past. It is not limited to the purpose used in the article, but also to be widely used as a commercial food.

또한, 본 발명은 종래의 두부제조공정 중 가공분리공정에 있어서 두부와 비지를 분리하는 과정으로부터 생콩이 미세하게 분쇄될 수 없어 비지에 묻어나 버려지는 량을 포함한 비지로서 버려지는 량이 많아 실제 두부수율이 적어질 수 밖에 없는 문제점과 상기 순차적인 공정으로부터 제조시간이 길어지는 문제점을 해결하고자 도2.에서 보여지는 바와 같이 두부제조용 콩을 메시콘베어가 장착된 열풍 건조 살균기에 통과하면서 80 ℃의 열풍이 콩의 외피에 가해져서 살균하고 이물질을 제거하는 살균제거공정과; 고속 로타리 박피기에서 콩의 외피와 콩의 눈을 제거하고 생콩을 여러 등분으로 분할하는 제거분할공정과; 액화 질소가스 투입구가 구비된 에어 제트 밀(AIR JET MILL)을 이용하여 콩을 미세분말로 분쇄하는 동결 분쇄공정;과 분쇄된 분말을 포집하여 포장하는 포장공정이 일련적으로 이루어져 있는 것을 특징으로 하고 있어 두부제조공정을 매우 단순화 하여 두부를 대량으로 생산할 때 상당한 두부제조시간의 단축으로 생산효율을 향상시킬 수 있고, 또한 상기 분말상태로 상용화 됨으로서 일반 수요자들이 널리 가정에서도 손쉽게 두부를 만들어 먹을 수 있도록 한 것이며, 본 발명인 대두건조분말을 의한 두부는 두부의 영양소가 손실되지 않아 영양과 맛 또한 종래의 두부보다 우수하다 할 것이며, 콩의 외피와 눈을 사전에 제거함으로서 실제적으로 두부수율을 높일 수 있도록 한 것에 본 발명의 목적이 있는 것이다.In addition, the present invention has a large amount of discarded as a bean containing the amount of raw beans can not be crushed finely from the process of separating the tofu and sesame in the process separation process of the conventional tofu manufacturing process to be buried in the bean curd actual actual tofu yield As shown in Fig. 2 to solve the problem that can not only be reduced and the production time from the sequential process is passed through the hot air drying sterilizer equipped with a mesh cone bearing soybeans tofu hot beans at 80 ℃ Sterilization removal process to sterilize and remove foreign substances applied to the outer shell of the; A removal and dividing process of removing the outer shell of the bean and the eye of the bean from the high speed rotary peeler and dividing the raw bean into several equal parts; Freeze grinding step of grinding the beans into fine powder using an air jet mill (AIR JET MILL) equipped with a liquefied nitrogen gas inlet; and a packaging process for collecting and packaging the powder pulverized This greatly simplifies the tofu manufacturing process, and when it is produced in tofu in large quantities, it can improve production efficiency by shortening the tofu manufacturing time. Also, it is commercialized in the powder state so that general consumers can easily make and eat tofu at home. Tofu by soybean dried powder of the present invention will not lose the nutrients of tofu, nutrition and taste will also be better than conventional tofu, by removing the skin and eyes of the beans in advance to actually increase the yield of tofu This is the purpose of the present invention.
