Abstract

This paper presents the modeling and experimental validation of an indirect solar drying chamber developed for mango dehydration under tropical climatic conditions. The system, designed at the Center for Studies and Research on Renewable Energies (CERER) and tested at the École Polytechnique of Dakar, has a drying capacity of 5 kg of mango slices arranged on three racks. A one-dimensional numerical model was developed to simulate heat and mass transfer during the drying process. The model integrates real-time climatic and thermal input parameters to reproduce the physical behavior of the dryer. Experimental validation focused on key variables, including air temperature, product temperature, relative humidity, mass loss, and shrinkage.
