As a starting point, the theoretical fundamentals related to the drying process and a transport phenomenon during drying was carefully explained. Drying experiments using the three different temperatures and two drying air velocities were performed for the sugar cubes with 3% of the initial moisture content. Thus, on the basis of drying curves the regression analysis was made to obtain diffusion coefficient. Thereafter the 2D simulation of one sugar cube was modeled by using the computational fluid dynamics (CFD) software ANSYS FLUENT. Through this step, the temperature distribution and velocity field of drying air were analyzed. Drawing on analogy of the heat and mass transfer research, the experimental and numerical results were compared. The findings support the calculation of the basic dimension of a belt dryer.
