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...

Multipass drying was simulated to evaluate the effect of tempering on drying process.

The effect of the initial moisture for tempering and the number of drying passes on the net drying time were analyzed.
