Abstract
Based on liquid diffusion model a two-dimensional finite element simulator
was developed for the drying of wheat. Simulations were carried out
for the drying of a single wheat particle in a novel rotating jet
spouted bed. The effects of the choice of the geometric model for
the wheat kernel, the temperature and flow rate of the drying air
on the moisture removal rate as well as kernel temperature were investigated.
Numerical experiments showed that the accuracy of the model geometry
chosen has great influence on the computed moisture removal rate
partly because of the way the moisture published diffusivity correlations
were obtained. Sample results are presented and discussed.
