Description

난방용 재생연료 및 그 제조방법{Regenerative solid fuel for heating and the producing method thereof}Regenerative solid fuel for heating and the producing method thereof

본 발명은 난방용 재생 연료에 관한 것으로서, 보다 구체적으로는 곤충의 분변토를 이용하여 에너지 효율 및 비용 효율이 우수한 재생 목재 연료를 제조하는 방법 및 제조된 재생 목재 연료에 관한 것이다.The present invention relates to a renewable fuel for heating, and more particularly, to a method for producing a recycled wood fuel having excellent energy efficiency and cost-effectiveness using insect feces, and to the manufactured recycled wood fuel.

기존의 에너지 개발은 사람들에게 환경을 저해하는 요소 중 하나로 인식돼 왔다. 산업혁명 이후 인류가 계속해서 사용해왔던 석탄에너지가 그러하고, 그 이후에 사용하기 시작한 석유에너지도 마찬가지이다. 에너지를 얻기 위해 이른바 화석연료를 사용하기 시작했고, 화석연료 사용으로 인해 자연은 점점 오염됐다. Conventional energy development has been recognized by people as one of the factors that harm the environment. The same is true of coal energy, which has been continuously used by mankind since the Industrial Revolution, and petroleum energy that has been used since then. They began to use so-called fossil fuels to obtain energy, and the use of fossil fuels made nature increasingly polluted.

석탄이나 석유, 원자력과 천연가스 등 오늘날 대표적으로 사용되고 있는 화석연료들은 나무에 비해 우월한 에너지를 만들어낸다. 인류는 화석연료들을 사용하면서부터 급속도로 성장했고, 삶이 윤택해진 것 또한 사실이다. 그러나 이러한 화석연료들은 사용할 때마다 오염을 가지고 오며, 무리한 채취활동으로 인하여 자연을 파괴하기도 하였다. 산업혁명이 시작된 이후 200년 동안은 인류 역사상 환경오염이 가장 심했던 시기이기도 하다.Fossil fuels used today, such as coal, oil, nuclear power and natural gas, produce superior energy to wood. It is also true that mankind has grown rapidly since the use of fossil fuels, and life has improved. However, these fossil fuels bring pollution whenever they are used, and nature has been destroyed due to excessive extraction activities. The 200 years since the start of the Industrial Revolution were also the most severe environmental pollution in human history.

인간의 삶이 조금 더 나아지는 데에 초점이 맞춰졌던 과거와는 다르게 인간의 가치와 자연의 가치에 초점이 맞춰지는 지금, 화석연료에 대한 회의적 시각이 늘어나기 시작하였다. 하지만 이미 포화된 에너지 사용량을 줄이기엔 어려움이 있으며, 그렇다고 당장 화석연료를 사용하지 않고 대체할 다른 대체에너지를 용이하게 얻을 수 있는 것도 아니다.Unlike in the past when human life was focused on making life a little bit better, now that the focus is on human values and the values of nature, skepticism about fossil fuels is starting to increase. However, it is difficult to reduce the already saturated energy consumption, and that does not mean that other alternative energy can be easily obtained without using fossil fuels right away.

이에 대체 자원 개발에 대한 논의가 이루어지기 시작했고, 더불어 기름값이 급속도로 올라갔으며 기후 협약 체결 등 다양한 정책적 압박으로 새로운 에너지 개발에 박차를 가하게 되었다. 이러한 단점을 극복하기 위해서 화석연료를 대체할 에너지를 찾기 시작했고, 그것이 바로 신재생 에너지라고 할 수 있다.As a result, discussions on the development of alternative resources began to take place, along with the rapid rise in oil prices, and various policy pressures, such as the signing of climate agreements, spurred the development of new energy. In order to overcome these shortcomings, they started looking for energy to replace fossil fuels, and that is what they call renewable energy.

신재생 에너지가 차세대 자원으로 각광받고 있는 이유는 화석연료와는 다르게 환경오염이 심하지 않고, 안정적으로 에너지를 생산할 수 있기 때문이다. The reason that renewable energy is spotlighted as a next-generation resource is that, unlike fossil fuels, it does not cause severe environmental pollution and can produce energy stably.

하지만 이러한 신개념의 신재생 에너지는 개발 단가가 비싸고 초기 설치비용이 비싸기 때문에 효율이 좋지 않고 또한 진입장벽이 높다는 문제가 있다. However, this new concept of renewable energy has a problem in that the development cost is high and the initial installation cost is high, so the efficiency is not good and the entry barrier is high.

이에 따라, 기존의 화석연료의 문제점을 해결하면서 에너지 효율 및 비용 효율이 우수한 대체 에너지에 대한 전 세계적인 요구가 증대되고 있는 실정이다.Accordingly, there is an increasing worldwide demand for alternative energy with excellent energy efficiency and cost efficiency while solving the problems of the existing fossil fuels.

본 발명은 상기한 바와 같은 시대적 요구에 부응하기 위해, 기존의 폐자원을 이용하여 용이하게 제작할 수 있어 비용 효율이 우수한 한편, 기존의 화석연료와는 다르게 환경오염의 문제가 없는 신재생 에너지원을 제공하는 것을 발명의 목적으로 하고 있다.In order to meet the needs of the times as described above, the present invention provides a new and renewable energy source that can be easily manufactured using existing waste resources and thus has excellent cost efficiency, and does not have a problem of environmental pollution, unlike conventional fossil fuels. It is an object of the invention to provide.

상기한 바와 같은 목적을 달성하기 위해, 본 발명은 곤충의 사육과정에서 얻어지는 분변토 및 식용곤충의 식품화 가공 과정에서 얻어지는 가공 부산물을 이용하여 제조된 연료용 펠릿을 제공하는 것을 특징으로 한다.

갈색거저리는 거저리의 일종으로 대한민국에서도 자생하는 딱정벌레류이다. 성충의 크기는 사람 새끼손가락 손톱급으로 작으며 이름처럼 갈색 계열의 색을 띠는 곤충이다. 갈색거저리 성충과 유충은 식물성 물질인 곡류나 채소 등을 먹으며 발육 기간이 3~4개월로 길다. 그리고 열악한 환경에서도 생존능력이 강한 곤충으로 먹이가 없거나 온도의 변화가 심해도 생존할 수 있으며, 이러한 생물학적 특성으로 연중 실내 대량 사육이 가능한 곤충종이다. Brown mealworm is a type of mealworm, a type of beetle that is native to Korea. The size of the adult is as small as that of a human little finger nail, and as the name suggests, it is an insect with a brownish color. Brown mealworm adults and larvae feed on plant substances such as grains and vegetables, and their growth period is as long as 3 to 4 months. In addition, it is an insect with strong viability even in a harsh environment, and can survive even without food or severe temperature changes.

갈색거저리는 잡식성으로 대부분의 농업부산물을 먹이로 발육시킨다. 일반적인 사료로 밀기울(소맥피), 미강(쌀겨), 옥수숫가루 등이 많이 사용되며 이것에 단백질 성분(어분, 콩가루, 비타민, 이스트 등) 및 기능성 성분을 혼합하여 먹이로 공급하기도 한다. 최근 대량 사육을 위해 다양한 부산물(볏짚, 작물 수확 후 남은 부산물, 남은 음식물 사료 등)을 이용한 사육이 시도되고 있다.Brown mealworm is omnivorous and develops most agricultural by-products as food. As general feed, wheat bran (wheat bran), rice bran (rice bran), and corn flour are often used, and protein ingredients (fish meal, soy flour, vitamins, yeast, etc.) and functional ingredients are mixed and supplied as food. Recently, for mass breeding, breeding using various by-products (rice straw, by-products left after harvesting crops, leftover food feed, etc.) has been attempted.

갈색거저리유충(고소애)을 식용으로 가공하기 전에 1~2일간 먹이를 주지 않고 방치하여 장속의 배설물을 모두 배설할 수 있도록 한다. 생체를 끓는 물에 데치거나 찜통에서 폐사시킨 후 건조되는 것을 막기 위해 물과 함께 얼려 냉동(-20'C) 보관하면 외부형태 및 색채가 훼손되지 않게 장기 보관할 수 있다.Before processing brown mealworm larvae (Gosoae) for food, leave them without feeding for 1 to 2 days so that all excrement in the intestines can be excreted. After blanching the living body in boiling water or dying it in a steamer, it can be stored for a long time so that the external shape and color are not damaged by freezing it with water and storing it frozen (-20'C) with water to prevent it from drying out.

살아있는 유충이나 죽은 신선한 유충을 열풍건조, 동결건조, 원적외선 건조 등의 방법을 사용하여 건조한 충체를 원형 그대로 또는 분말로 가공하여 냉장 및 냉동 보관할 수 있으며, 갈색거저리유충(고소애)은 단백질(50%)뿐만 아니라 지방(33%)도 풍부한데 불포화지방산을 다량 함유하고 있어 혈관질환 및 성인병 예방에 도움을 준다. 추가로 탄수화물(9.3%)도 포함되어 있다. 식재 외에 약재로도 사용되는데 기침, 가래, 조혈, 중풍치료에 효과가 있는 것으로 알려져 있다. Live larvae or dead fresh larvae can be refrigerated and frozen by processing the dried worms in their original form or into powder using methods such as hot air drying, freeze drying, and far-infrared drying. ) as well as fat (33%), it contains a large amount of unsaturated fatty acids, which helps to prevent vascular diseases and adult diseases. It also contains carbohydrates (9.3%). In addition to food, it is also used medicinally, and is known to be effective in treating cough, phlegm, hematopoiesis, and stroke.

본 발명은 갈색거저리의 사육 과정에서 얻어지는 분변토를 포함하는 것을 특징으로 하고 있다. 곡식의 부산물을 먹고 자란 갈색거저리 애벌레의 분변토는 건조가정을 통해 수분을 제거해주면 쌀겨와 비슷한 양태로 연소한다. The present invention is characterized in that it contains fecal soil obtained in the process of breeding brown mealworm. The fecal soil of brown mealworm larvae grown on by-products of grain burns in a manner similar to rice bran if moisture is removed through drying.

도 1의 (b) 및 (c)를 살펴보면, 갈색거저리의 분변토를 건조시킨 후 여기에 불을 붙여보면, 불꽃을 내며 연소하기보다는 작은 불씨가 번지는 형태로 타들어가는 것을 확인할 수 있는데, 한번 불이 붙으면 쉽게 소화되지 않고 연속적으로 이어지며 타들어가는 형태로 연소된다. 이러한 연소방식은 옛부터 아궁이 문화가 발달한 우리나라에서 나무와 함께 주 난방원료로 사용해온 쌀겨와 같은 연소방식이다. 이는 장시간 은은한 열기를 제공할 수 있는 연소방식으로서, 매우 효율적인 열에너지 발생방식이다. 1 (b) and (c), if you light the fecal soil of brown mealworm after drying it, it can be confirmed that it burns in the form of a small flame spreading rather than burning with a flame. If this sticks, it is not easily extinguished, continues continuously, and is burned in a flammable form. This combustion method is the same as rice bran, which has been used as the main heating material together with wood in Korea, where the furnace culture has been developed since ancient times. This is a combustion method that can provide gentle heat for a long time, and is a very efficient heat energy generation method.

본 발명의 재생 연료인 펠릿은, 식물을 주식으로 하는 곤충의 사육과정에서 얻어지는 분변토에, 식용곤충의 식품 가공시 얻어지는 가공부산물인 오일을 적당량 섞어서 반죽한 후 굳혀서 제조할 수 있다. 예를 들어, 식용곤충을 1~2일 정도 절식시켜 내장을 비운 뒤 계속 절식 시키거나 별도의 장치를 이용하는 등의 방법으로 폐사시킨 뒤, 세척 및 건조 후 저온압착 방식으로 탈지하여 얻어지는 오일을 사용할 수 있다. 분변토와 오일은 약 7~9:1~3의 비율로 혼합하여 반죽할 수 있으며, 바람직하게는 분변토와 오일을 8:2의 비율로 혼합하여 펠릿을 제조한다. 곤충 분변토와 곤충 오일을 혼합한 반죽은 적당항 형태로 빚어낼 수 있으며, 본 발명에서는 폭보다 길이가 긴 기둥 형태인 것이 바람직하다.The pellet, which is a renewable fuel of the present invention, can be prepared by mixing an appropriate amount of oil, which is a processing by-product obtained during food processing of edible insects, with fecal soil obtained in the process of breeding insects, mainly plants, and kneading the mixture. For example, you can use the oil obtained by fasting edible insects for 1 to 2 days, emptying their intestines, and then continuing fasting or using a separate device to kill them, and then wash and dry them and then degrease them using a low-temperature compression method. have. The fecal soil and oil can be kneaded by mixing in a ratio of about 7 to 9: 1 to 3, and preferably, the fecal soil and oil are mixed in a ratio of 8: 2 to prepare pellets. The dough mixed with insect fecal soil and insect oil can be made into a suitable shape, and in the present invention, it is preferable to have a columnar shape having a length longer than the width.

본 발명에서는 또한 상기 펠릿을 폐목과 혼합하여 제조되는 재생연료를 제공한다. 예를 들어, 본 발명의 일 실시태양에 따르면 상기 재생연료는 산림에서 얻어지는 장작용 폐목에 길이방향으로 홈을 내고 그 내부에 기둥 형상의 펠릿을 삽입하여 고정시킨 것을 특징으로 한다(도 2).The present invention also provides a renewable fuel produced by mixing the pellets with waste wood. For example, according to an embodiment of the present invention, the renewable fuel is characterized in that a longitudinal groove is made in a long-acting waste wood obtained from a forest, and column-shaped pellets are inserted therein to be fixed (FIG. 2).

이하에서는 보다 구체적인 실시예를 통해 본 발명을 상세히 설명하고자 하나, 하기의 실시예는 본 발명의 범위를 제한하는 것은 아니다.Hereinafter, the present invention will be described in detail through more specific examples, but the following examples do not limit the scope of the present invention.

[실시예][Example]

1. 분변토1. fecal soil

갈색거저리 유충(밀웜) 사육 농가로부터, 사육과정에서 얻어지는 분변토를 입수하였다. 경기도 화성에 위치한 갈색거저리 유충(밀웜) 사육농가로부터 분변토를 입수하였으며, 해당 농가에서는 밀기울과 미강 만으로 밀웜을 사육하였다. 입수한 분변토는 볕이 잘 들고 통풍이 잘되는 곳에서 24시간 동안 골고루 건조시켰다.
