Shape Characterization for a Simple Diffusion Analysis of Air Drying of Grains

Abstract

ABSTRACT This work proposes a simple method to characterize which of the elemental geometries (slab, cylinder or sphere) would be a better approximation for the diffusion analysis of air drying of grains having “nonconventional shapes.” The method is tested with experimental drying data obtained for soybeans, rough rice, wheat and peanuts.
