Abstract:
Thin-layer drying curves of shelled corn were determined at 40, 50, 60 and 70 °C and 'high' relative humidity, for a moisture range from 21 to 12%, dry basis. Simulation of the experimental drying curves was performed by means of Fick's second law for diffusion out of a sphere, with constant diffusion coefficient. An accurate fitting of the experimental data was obtained assuming an equilibrium value given by the desorption isotherm of grain (static equilibrium moisture content). A reasonable agreement was also found between the dynamic equilibrium moisture content (obtained from the drying data) and the static one. A criterion was proposed, based on the monolayer moisture content, where the static equilibrium moisture content accurately fits the experimental drying curves. © 1991 Academic Press Limited.
