Abstract

This study is concerned with performance analysis of solar drying system for red chili. Red chili was dried to final moisture content of 10% w.b from 80% w.b in 33h using this system. In this study, energy and exergy analyses of the solar drying process were performed for red chili. Using the first law of thermodynamics, energy analysis was carried out to estimate the useful energy gained from the collectors. However, exergy analysis during solar drying process was estimated by applying the second law of thermodynamics. The specific energy consumption (SEC) was 5.26kWh/kg. The values of evaporative capacity and improvement potential were from 0.13kg/s to 2.36kg/s and 0W to 135W, respectively. The efficiencies of the solar collector, drying system, pick-up, and exergy were 28%, 13%, 45%, and 57% respectively, at an average solar radiation of 420W/m2 and a mass flow rate of 0.07kg/s.
