In many countries of the world, the use of solar energy in the agricultural area to preserve vegetables and fruits has shown to be practical, environmentally responsible approach. Solar heating systems to dry food crops can improve the quality of the product, while reducing wasted produce. The study is to calculate changes in the weight of the product without removing it from dryer. Experiments were calculated to study the effect of process parameters (temperatures, thicknesses) on the drying kinetics of potatoes and papaya slices. In the drying kinetics using direct solar cabinet dryer and the influence of weather parameters such as ambient air temperature, cabinet temperature on drying of potato and papaya slices were evaluated. It was observed that the drying process was characterized by a decrease in the moisture ratio with time. Initially, a higher drying rate was obtained followed by slower moisture removal rate. Increased drying rate and decreased drying time were observed with increase in the dryer temperature. In this study the selected product was investigated by direct solar cabinet dryer. During drying, it was observed that the temperatures inside the solar cabinet were increased to 40oC & 41oC when the maximum ambient temperature was only 30oC & 32oC. The papaya and potato slices of 3, 4 and 5 mm thicknesses could be dried and 67.38, 69.25, 71.5% wet basis moisture loss, respectively 67.75, 71, 73% moisture loss. The drying rate also increased in Direct solar cabinet drying when compared to open sun drying in which drying rate get increased while the radiation increased. By analyzing the samples with ANOVA overall samples shows maximum acceptability of the product in all the parameters.
