증기식 밤 박피기 및 밤 박피방법{Steam Chestnut Peeler and Peeling Method}Steam Chestnut Peeler and Peeling Method

본 발명은 밤외피제거기로 밤(생율)의 외피를 일차로 제거한 밤의 내피를 고온 고압의 증기와 압축공기를 이용하여 밤표면 과육에 상처를 주지않고 밤 내피를 완전히 제거하는 증기식 밤 박피기 및 이를 이용한 밤의 박피방법에 관한 것이다.The present invention is a steam balm peeler that completely removes the night endothelium without damaging the night surface pulp by using steam and compressed air of high temperature and high pressure to remove the inner skin of the chestnut (birth rate) as a night skin remover. And it relates to a night peeling method using the same.

우리나라 밤은 씨알이 굵고 과육이 단단하며 당도와 기타 영양성분의 함량이높아 크기와 품질면에서는 세계적으로 가장 우수한 밤이라고 알려져 있다. 그러나 우리나라 밤은 품종특성상 밤송이의 박피작업이 수작업으로 하기는 매우 어렵기 때문에 본 발명자가 개발한 국내산 밤의 외피 박피기(특허번호 제 0229733호, 1999. 8. 18 등록)를 사용하여 밤외피를 제거한 후, 본 발명의 내열성 고무마찰판, 고압분사노즐, 원통형 박피실, 상부덮개판, 실리콘 부착 배출판 등으로 구성된 증기식 밤 박피기에 공급한 다음 고온고압의 증기 및 압축공기를 분사하여 밤내피를 제거하는 장치에 관한 것이다.Korean chestnut is known to be the best chestnut in the world in terms of size and quality due to its thick grain, hard flesh, and high content of sugar and other nutrients. However, because Korean chestnuts are very difficult to carry out the peeling work of chestnuts due to the characteristics of varieties, the skins of chestnuts using the domestic skin peelers (patent number 0229733, registered on August 18, 1999) developed by the present inventors After removal, it is supplied to a steam chest peeler composed of a heat-resistant rubber friction plate, a high pressure spray nozzle, a cylindrical peeling chamber, an upper cover plate, a discharge plate with silicon, and the like by spraying steam and compressed air at a high temperature and high pressure. A device for removing.

세계의 년간 밤 생산량은 45만톤에 달하며 이중 10만톤 규모를 생산하고 있는 한국은 중국에 이어 세계 제2위의 밤 생산국으로 알려져 있으며 년간 1억불 규모의 수작업으로 박피한 밤을 일본에 수출하고 있다. 유럽의 주요 밤 생산국은 이태리, 터어키, 스페인 등으로서 이들 지역의 밤은 박피작업이 매우 쉬운 품종으로 대형의 LPG 화염식 박피장치를 사용하여 박피밤을 가공하여 마론 그랏세, 밤 캔디, 밤 퓨레 등의 고부가가치 밤 가공제품을 생산판매하고 있다. 국내산 밤은 품질과 크기가 우수하나 밤내외피가 밤 과육 표면에 강하게 접착되어 있어 기계적인 박피작업이 매우 어려우므로 지금까지 국내 대부분의 밤 박피작업은 절단칼을 이용한 수작업에 의존하고 있다.The world's annual chestnut production reaches 450,000 tons, of which the country produces 100,000 tons, which is known as the world's second largest producer of chestnuts after China, and exports $ 100 million of hand-sewn chestnuts to Japan each year. The major European chestnut producers are Italy, Turkey, and Spain. Chestnuts in these regions are very easy to peel, and large-size LPG flame-repellents are used to process the peeled chestnuts, such as marron grasse, chestnut candy, and chestnut puree. Produces and sells high value-added chestnut processed products. Domestic chestnuts are excellent in quality and size, but since the inner and outer skins are strongly adhered to the chestnut pulp surface, mechanical peeling work is very difficult, so most of the chestnut peeling works in Korea have depended on the manual work using cutting knife.

종래의 밤 박피장치는 절단칼이 고정된 원통형 실린더 내부에 밤 원료를 넣고 하부 원판을 고속으로 회전하여 밤 내외피를 동시에 절단하여 제거하는 회전절단식 밤 박피장치와 LPG 열원을 이용한 화염식 밤 박피장치등이 있으나 아직 실용화되지 않고 있다. 회전절단식 밤 박피장치는 원통형 내부에 다수의 절단칼날이 고정되어 있고 하부에 회전원판이 있으므로 밤 원료가 들어가 고속으로 회전하면서 밤내외피가 동시에 절단되는 원리를 사용하고 있다. 그러나 밤 박피작업 처리용량이 적으며 밤 내외피가 동시에 절단되어 박피작업 과정중 중량 손실량이 50%로 매우 높은 단점이 있다. 화염식 밤 박피장치(특허제 0229734호, 1999. 8. 18 등록)는 LPG 열원을 이용하여 700℃ 이상의 고온의 연소실 내부로 원통형 회전연소장치를 설치하고 이 내부로 외피를 60℃에서 1시간 정도 건조한 밤 원료를 20-30초 동안 통과시켜 순간적으로 밤내외피를 연소시킨 후 연속 마찰식 밤내외피 제거기를 이용하여 밤내외피를 제거한다. 이것은 대량의 밤원료를 연속적으로 처리할 수 있는 장점이 있지만 평균 박피율은 70-80%로 비교적 낮으며 기계설비 규모가 크고 박피시 밤 표면과육이 고온으로 인하여 열침투 현상이 심화되어 고품질의 박피밤 생산이어려운 문제점이 있다.Conventional night peeling device puts chestnut raw material inside the cylindrical cylinder fixed to the cutting knife and rotates the lower disc at high speed to cut and remove the chestnut inner skin at the same time, flame-proof night peeling using LPG heat source There are devices, but they have not been put to practical use yet. Rotary cutting type night peeling device uses a principle that is cut at the same time the inner and outer skin at the same time while the raw material enters the rotation at high speed because a plurality of cutting blades are fixed in the cylindrical interior and there is a rotating disk at the bottom. However, the night peeling process is small and the inner and outer skins are cut at the same time, so the weight loss during the peeling process is very high as 50%. Flame chest peeling device (Patent No. 0229734, registered on August 18, 1999) installs a cylindrical rotary combustion device into the combustion chamber of 700 ℃ or higher by using LPG heat source, and the inside of the shell at 60 ℃ for about 1 hour. After passing through the dry chestnut raw material for 20-30 seconds, the chestnut shell is burned instantly, and then the chestnut skin is removed using a continuous frictional chestnut skin remover. This has the advantage of being able to process a large amount of chestnut raw material continuously, but the average peel rate is relatively low, 70-80%, and the size of the machine is large, and the skin penetration of the chestnuts at the time of peeling intensifies the heat penetration phenomenon due to the high temperature. Chestnut production has a difficult problem.

본 발명은 종래 회전 절단식 밤 박피장치가 갖고 있는 박피공정중 과대한 밤 중량 손실과 과육표면 손상을 방지하고 화염식 밤 박피장치의 박피율 저하, 박피밤표면의 열침투현상 심화, 기계설비 규모 과대 등의 문제점을 개선하고 자, 밤 원료의 외피부분을 밤외피제거기로 제거한 후, 내열성 고무마찰판이 설치된 원통형 박피실에 투입하여 고온고압의 증기와 압축공기를 일정시간 분사시켜 밤내피를 밤과육표면에서 분리시켜 박피율을 높이고, 박피시 밤 표면과육의 손상을 방지하며, 박피공정의 설비규모를 최소화하는데 있다.The present invention prevents excessive night weight loss and pulp surface damage during the peeling process of the conventional rotationally cut chestnut peeler, and reduces the peel rate of the flammable chestnut peeler, deepening the heat penetrating phenomenon of the peeled chestnut peeler, and equipment scale. In order to improve the problems such as overheating, the skin part of chestnut raw material is removed with chestnut skin remover, and then it is put into a cylindrical skin chamber equipped with a heat-resistant rubber friction plate, and sprays hot and high pressure steam and compressed air for a certain time to make chestnut skin flesh. Separation from the surface to increase the peel rate, to prevent damage to the surface flesh at the time of peeling, and to minimize the scale of the peeling process.
