Traditionally, vegetables and fruits are dried outdoors in the sun without any protection against external pollutants or in direct dryers, causing very significant (nutritional and quantitative) losses. The objective of this work is to conduct a numerical simulation of a solar dryer in natural convection. For simulation, we use COMSOL software. The numerical resolution generated the heat flows in the system, the temperature field, the air velocity field and the pressure variation in the system. The variation of the temperature of 60°C in the dryer obtained by vacuum simulation is in line with the tolerated temperatures for the drying of fruits and vegetables.
