AB - A mathematical model describing unsteady simultaneous one-dimensional heat and mass transfer between gas phase and wet particulate material dried in a vibro-fluidized bed is presented in this paper. Heat and mass transfer between gas phase and particle surface are calculated
using well known expressions for the case of packed bed, while mixing of the particles is taken into account by means of the diffusion term in the differential equations, using an effective particle diffusion coefficient. Internal moisture transport is calculated on the basis of modified Luikov drying theory. A control volume numerical method is used for discretization of the coupled partial differential equations system. Results obtained on the basis of numerical simulation are compared successfully with corresponding experimental data using wet poppy seeds as the drying material.
