Abstract
A cylindrical focusing solar food dryer made with aluminum-laminated acryl film was demonstrated for the dehydration of agricultural product and its perfomance was analyzed with respect to the solar energy utilization and its scale-up technology. With one square meter reflector and a 74 cm copper pipe absorber, the heat exchange efficiency between air stream and absorber was 1.39 %. The installation of circular segment-baffle increased 33 % of the efficiency. In dehydration of radish-cut with this drier, 58 % of fuel consumption was saved. The relationship between reflector area and heat energy utilization was established for the scale-up purpose.
알루미늄-아크릴 필름을 사용하여 제작(製作)한 곡면(曲面) 집광장치(集光裝置)에 의(依)한 공기(空氣)의 가열(加熱)과 가열(加熱)된 공기(空氣)를 이용하여 농산물(農産物)의 건조(乾燥)에 이용(利用)하는 실험(實驗)을 통하여 다음과 같은 결과를 얻었다. 1. 공기(空氣)를 열(熱) 교환(交換) 매체(媒體)로 하고
