A solar dryer was used to dry Jew's mallow (Corchorus olitorius L.) and okra (Hibiscus esculentus L.). The drying procedure depends on using heated air of 60 degrees celius on average. The results revealed that the rate of drying was high in the first 3 hours and then slowed down during the remainder of the drying time. The duration of drying for both Jew's mallow and okra was on average 22.5 hours and 40 hours respectively, and the moisture removed during that period was about 72-75%. The quality of the dried product was acceptable to the consumer and was considered to be nutritionally satisfactory. The storage of dried products for 32 weeks at room temperature showed no adverse effect on quality or change in chemical composition. A technofeasibility study was carried out to determine the economic possibility of using this dryer in rural areas.
