Abstract

This study focuses on a drying system consisting of a flat air solar collector coupled longitudinally to a drying chamber in the climatic conditions of tropical regions and the case of Togo was presented. The study was carried out using mathematical models obtained by writing the laws of energy conservation in the different components of the system. Simulations were achieved using experimental measurements of daily solar radiation and ambient temperature on a typical day in Lomé (Togo). The results highlight the importance of solar radiation and the use of fins on the performance of the drying system. It reveals that an optimal range of solar daily radiation for the proposed insulator for drying is 400 W/m2 to 1000W/m2, with an ambient air speed of 1.5 m/s to 4.5 m /s and a temperature variation of 20°C to 45°C.
