  • In this study, peeling test of the Altari radish on kimchi pre-processing system for mechanization was performed with the longitudinal plane peeling type with wider cutting blade than that of the peeled chip's. To determine the optimum cutter shape to match this plane peeling type, the peeling tests depending on variable cutting speed, rake angle and blade angle using the blade with thickness as 2 m and width as 50mm were performed, and the patterns of the peeled chips and peeling resistances were investigated. As the result of the tests, the rake angle of the blade with clean peeled surface of the Altari radish was over $45^{\circ}$, and the blade angle and rake angle with the minimum peeling resistance was $20^{\circ}\;and\;60^{\circ}$, respectively. The optimum peeling conditions were; the peeling speed 0.2m/s, blade angle $20^{\circ}$ and the rake angle $60^{\circ}$, and the peeling resistance of each blade was 15 N.

  • The chestnut is a well-known and important forest product in Korea. The annual production of chestnut is about 100, 000tons and its cultivating area is 80, 000ha. However, the peeling process of outer and inner skins of chestnut is very difficult due to hardness and adhesiveness of chestnut skin. The peeling process of chestnut was operated by manual work and the performance of chestnut peeling machine is very low. The purpose of this study is to develope the prototype of new chestnut peeling system. The hardness of chestnuts was tested with six different drying conditions and its range was from 949$g/mm^2$ to 2, 149$g/mm^2$. The hardness of chestnuts was decresed gradually during the drying process. The chestnut peeling Process includes sorting, storage, drying, outer skin cutting, flame peeling, continuous frictional skin peeling, and inner skin cutting operation. The developed chestnut peeling system consists of outer skin cutter, flame peeler, continuous frictional skin peeler and inner skin cutter. The system can peel domestic chestnuts at 150$kg/hr$ with peeling rate of 78%.

  • This study was conducted to determine the optimum blade shape for peeling Altari radish. To figure out the required peeling force according to various angles of blade and rakes of peeling cutter, two peeling tests such as circumferential peeling and longitudinal peeling of Altari radish were carried out. Based on the pretest results, which performed to investigate the applicability of the optimum shape of cutter and to find out the cutting pattern according to the lapse of days after harvesting the radish, the peeling depth and width of the blade were fixed at 2 mm and 10 mm. From two methods of circumferential and longitudinal peeling test, the angles of rake and blade as cutter shape factors were affected on peeling force. But the peeling speed was not affected on it under the safety speed as 0.2 m/s, without blade vibrating on peeling operation. The rake angle was more effective factor than the blade angle, and the optimum angles of blade and rake were 10$^{\circ}$ and 55$^{\circ}$ respectively. The cutting surface by the longitudinal peeling was more smooth than that by the circumferential peeling. There was no problem in peeling work during 4 days after harvest because the freshness of the Altari radish was maintained.

  • SUS bars such as 304, 316 series have been widely used to manufacture the adapters and fittings, which include many hexagonal bolts and nuts. The purpose of this study is to investigate the characteristics of heat conduction of SUS bar according to rotation of cutting tool. Temperature distribution in SUS bar can be achieved by using numerical analysis of heat conduction, thus it may be of help to the optimal operation of peeling machine. As the results, as the rotation of cutting tool is increased, both maximum cutting temperature and depth of heat conduction are decreased. Moreover as the angle of SUS bar is increased, it shows that maximum cutting temperature is decreased, on the other hand, depth of heat conduction is increased.

  • 탈피 방법에 따른 감자류와 당근의 탈피효율과 제품의 품질을 연구하였다. 재료의 구형도와 중량이 탈피효율에 미치는 영향을 조사하였으며, 탈피 후에 표피 조직감의 변화를 Rheometer로 측정하고 세포조직의 변화를 비교하였다. 연마형 회전식 기계적 탈피의 조건은 감자는 300rpm에서 90초, 고구마는 300rpm에서 70초, 당근은 300rpm에서 60초 이었다. 탈피 손실율은 재료의 구형도와 중량에 의해 영향을 받았다. 알카리 탈피의 최적조건은 10% NaOH 끓는 용액에서 감자는 90초, 고구마는 300초 이였으며 당근은 6% NaOH 끓는 용액에서 60초 이었다. 탈피에 의한 표피 조직감의 변화는 Rheometer의 절단력 실험에 의해 명확히 나타났고. 이것은 광학현미경을 이용하여 관찰된 표피 조직 변화현상으로 설명될 수 있었다. 알카리 탈피에서 일어나는 표피 조직의 변화현상은 표면 세포내의 전분입자의 호화와 밀접한 관계가 있음을 알 수 있었다.

  • An Altari radish pre-processing system, which feasible to process automatically such operations as leaf and root tail cutting and root peeling, for kimchi production was accomplished based on the foregone serial studies. In this study, the performances of the developed prototype machine, considered as a commercializing level, were analyzed and evaluated. The prototype machine attached Tiny PLC automatic control system was performed the sequent function as the rate of successful peeling was more than 98% for the Altari radish less than 70 mm diameter of a radish. The operating efficiency of this was 9 see/each, 128 kg/h, and it means as much as $5{\sim}6$ times that of a woman labor's. The sanitation and taste of the mechanized-processed Altari radish kimchi was almost same as that of the handmade. And they were suitable for manufactory of kimchi as the both short term ripening and storing kimchi. Developed machinery with one peeling device and two peeling devices that compared with hand processing, it was analyzed that the break-even yearly working days were 28 days and 19 days, and the break-even yearly processing amount were 28,700 kg, 32,400 kg, respectively.

  • 작약의 양질약재 생산을 위한 기초 자료를 얻고자 건조과정중 박피시간별 절단과 무절단 그리고 열풍건조 온도를 달리하여 시험한 결과를 요약하면 다음과 같다. 박피시간이 길어질수록 건조시간은 통뿌리보다 절단한 것이 건조온도가 단축되었으며, $30^{\circ}C$에서 $60^{\circ}C$까지의 건조온도에서 건조온도가 상승할수록 온도상승의 효과는 감소하였다. 작약의 주 약용성분인 paeoniflorin 함량은 무박피 절단형태로 열풍온도 $30^{\circ}C$에서 건조한 작약이 3.48%로 가장 높은 함량을 유지하였고, 120분 박피후 통뿌리로 $60^{\circ}C$에 열풍건조한 작약은 2.29%로 건조과정중 많은 양이 손실되어 가장 낮게 나타났다. 건조작약의 외부색택은 통뿌리로 $60^{\circ}C$에서 열풍건조했을 때 흑갈색으로 변하는 정도가 가장 심했다. 따라서 작약 수확후 건조과정 중 건조시간 단축과 약효성분 그리고 색택면에서 건조전의 처리 방법은 무박피 절단형태가 장시간 박피 원형형태보다 우수한 것으로 판단된다.
