太陽熱을 利用한 食品乾燥에서 silica gel의 活用效果 = Effect of silica gel on food dehydration of onion by solar energy

다국어 초록 (Multilingual Abstract)

This experiment was carried out to elucidate the drying characteristics of onion and dehumidifying effect of air using the silicagel and to reuse it by solar collector.
The results were summarized as follows.
1. It takes 14 hours to regenerate to silicagel of 8% moisture content from saturated silicagel conditions of 28℃ temperature and 55% relative humidity.
2. When sample was recycled through solar collector, the result of drying was 1/2 times more efficient than that of mat drying.
3. Average thermal efficiency of solar collector was 25% during the experimental period.
4. Browing extent was reduced to 1/2 times at heated air blow drying system using drying chamber.
