In an airbased solar collector, the heated air flows naturally or by a fan into the drying chamber where the crops are placed. In a waterbased solar collector, there is a heat exchange between water and air in a drying chamber. As a result, hot air will remove moisture and dry crops. The nonconcentrating type has low concentration ratio.
