Abstract
In this work, the model of particles for microwave drying by means of assisted force convection for blueberry leaves is described. A one-dimensional particle model is made in the direction of the thickness of the leaf. Only the phases of water during drying are considered. The mass and energy equation in the particle model develops. The effective diffusivity and the Arrhenius equation for the water phase (liquid and vapor) are considered in the mass equation. The energy equation considers the Lambert-Beer equation. The simulation is performed for different cases of microwave powers (100, 300, 400 W) and temperatures (50, 60 and 70 °C) The activation energy and the pre-exponential factor in the Arrhenius equation are taken from the kinetic analysis prior to this Work The temperature and mass profiles for some experimental and theoretical cases are compared, and it is observed that the model considered gives good results of adjustment between the experimental and the theoretical.
