Drying simulation of corn with tempering
This work presents a diffusion model and experimental investigation of corn drying with tempering. The model solves numerically the diffusion equation for a hygroscopic porous solid consisting of two concentric spheres (starchy endosperm and pericarp) with different shell thickness and relative resi...
