Abstract
Summary: Pick's law of diffusion (moisture flux proportional to the moisture gradient) for diffusion out of spheres was successfully applied to describe the drying of grain sorghum. It was found that the diffusion coefficient of water was independent of moisture content in the approximate range of 21–6% (dry basis) moisture content. An Arrhenius type temperature dependency of moisture diffusivity was found, the energy of activation being 7.5 kcal/g mol.Keywords
