The main objective of this study is to estimate the drying parameters of cassava using an indirect solar dryer equipped with a sensible heat energy storage system. This dryer, which uses stones as storage material and made of wood and plywood, was used to dry a quantity of 12.2 kg of cassava. Drying parameters relating to drying curves and drying efficiency of cassava were established and studied. The drying curves were modeled using semi-empirical models. The results showed that the water content of cassava decreased from 159.12 g H2O / 100 g dry matter to 13.32 g H2O / 100 g dry matter. With a collector and drying efficiency of 56.64% and 29.39% respectively. The Weibull distribution model allows a satisfactory modeling of the drying curve, with an r2 = 0.988, a χ2 = 0.000896, and an RMSE = 0.0288.
