For this purpose, the solution of liquid diffusion equation was fitted to the experimental moisture ratios for drying air temperatures between 40 and 60 degrees C and velocity 1.5 m s(-1). In order to make a comparison, the predictions of liquid diffusion equations for a spherical and finite cylindrical geometry were also fitted to the experimental results. Modeling was performed by selecting the diffusion coefficients in diffusion equations in such a manner as to minimize the sum of the squared differences between the experimental results and the theoretical predictions. It was found that the liquid diffusion model, based on a prolate spheroid geometry, explains single-layer drying behavior of rough rice well. It was also found that the model, based on a prolate spheroid geometry, has better agreement with the experimental results than the other geometries.en10.1007/s00217-007-0593-0info:eu-repo/semantics/closedAccessRiceDryingThin-LayerLiquid DiffusionProlate SpheroidParboiled Paddy ComponentsArticle2264787793Q2WOS:0002525400000192-s2.0-38349169229Q2
