Currently, the cutting oil supply device is not equipped to cool the cutting oil. Therefore, additional cooling device should be connected to cool the cutting oil. This has the disadvantage of increasing the size of the device and reducing its cooling capability. To overcome these shortcomings, cooling coils are applied to the outside of the cutting oil filtering device to develop a heat exchanger filter for simultaneous coolant filtering and cooling to improve the compactness of the cutting oil supply device and cooling capability of the cutting oil. For the development of heat exchanger filter, flow and heat transfer analysis were performed. Due to the small heat transfer area of 10 cooling coils, less heat exchange occurred. In the 20 cooling coils, the coolant cooling coils prevented smooth flow of the cooling oil in the heat exchanger filter. The cooling efficiency of the 15 cooling coils were best, and the cooling temperature decreased non-linearly as the supply flow rate of the cutting oil increased.

우리밀의 소비촉진과 제면적성을 구명하기 위하여 국내육성 11품종 (조광밀, 그루밀, 은파밀, 탑동밀, 우리밀, 올그루밀, 알찬밀, 고분밀, 금강밀, 서둔밀, 수원 265호)과 수입밀 2품종(DNS(Dark Northern Spring Wheat), ASW(Australian Standard White))에 대한 제면 가공특성을 분석하였다. 삶은 건면의 조직감에서 탄력성은 국산밀이 0.59-0.79 범위이었으며, 수입밀은 0.55-0.57로 낮았다

우리밀 생산농가의 소득증대와 소비촉진을 위한 연구로써 국내 육성 11개 밀품종인 조광밀, 그루밀, 은파밀, 탑동밀, 우리밀, 올그루밀, 알찬밀, 고분밀, 금강밀, 서둔밀, 수원 265호와 수입밀인 DNS Dark Northern Spring Wheat) 및 ASW (Australian Standard White) 등에 대하여 반죽특성을 살펴보았다. 밀가루 반죽의 점착성은 조광밀이 81.8g으로 가장 컸으며, 국산밀의 평균이 54.0 g, 수입밀
