Modelisation et simulation d'un sechoir solaire diurne et nocturne

Abstract

In French Guiana, like in the countries of the African continent the access to the electrical energy is often a problem. For this reason, isolated agricultural farms requires the implementation of autonomous solar drying devices, easy to install and robust. We propose in this paper to present a solar dryer prototype to answer this problematic. The device is designed to dry agricultural products along day and night while maintaining a temperature and the air flow constant. The modelling of the dryer decomposed into subsystems using the nodal approach is also presented. The simulation results obtained are compared with experimental results and commented.
