ABSTRACT
In this paper, we present a study of convective drying for wet agricultural product by hot air. The system used is a tunnel dryer, it works with different sources of energy (solar, gas, electric), and has been conceived to dry several agricultural products. This system operates in open loop for adjustable air in temperature and velocity. The objective of this work is to establish a mathematical model describing the phenomena of heat and mass transfer at the product layer and in the air. The drying process is simulated under real operating conditions based on a thin layer model and experimental drying kinetics.
