Modeling convective and intermittent drying of agricultural products
The purpose of this work is to quantify the energetic interest of convective and
intermittent drying process of natural products. This drying mode has been achieved
within a climatic blower. This laboratory device permitted us to achieve several tests for
different conditions of drying for apples, carrots and peppers. This study permitted to
appreciate the capacity of the model to describe the different drying periods. In the
continuous case, a variation of the air velocity permitted us to find the most economic
velocity for the drying of thin layer products. In the intermittent case, the numerical
simulation profiles give us more information on what happens really to the product
during periods of stop. Besides, the drying kinetics at the retaking increases with the air
temperature. Then, we gain in energy and in global drying time.
