Abstract
In this study, thin layer drying of tomato slices under open sun drying and double slope solar dryer was conducted. The drying effect on exergy loss, exergetic efficiency, dryer efficiency, pickup efficiency, energy utilized, thermal and drying chamber efficiency has been obtained. It has been observed that the solar dryer with double slope had more efficiency than the open sun drying. The exergy loss range from 1196.82 to 11,758.18 kJ/kg having an average value of 6302.47 kJ/kg, the exergetic efficiency varied from 67.19% to 81.17% with an average value of 70.20%, respectively. The value of pickup efficiency varied from 10.89% to 14.33% with an average value of 12.22% with the dryer efficiency varying from 11.58% to 44.76% with an average value of 25.76%, respectively. The energy utilized ranged from 19.23 to 76.73 kJ/s with an average value of 55.2 kJ/s, the thermal efficiency is said to be varied from 5 to 14% and the drying chamber efficiency is said to be range from 9.70 to 77.52% with an average of 57.48% for the entire duration of the experiment. A comprehensive evaluation yielded that the double slope solar dryer was best suited for drying the samples.
