Abstract:
The process of moisture extraction from unhusked Korean rice is modeled with the use of a diffusion model. The diffusion coefficient is determined, which makes it possible to reconstruct the dynamics of the moisture distribution in a cylindrical sack filled by rice. It is demonstrated that the results of calculations performed for different values of the initial humidity are in reasonable agreement with experimental data obtained in the case of drying of unhusked rice in an acousto-convective drier. Results testifying to significant intensification of acousto-convective drying as compared to natural drying are obtained.
Keywords:
acousto-convective drying of unhusked Korean rice, moisture extraction, coefficients of diffusion and moisture extraction.
