Abstract | This article uses a liquid diffusion model to describe convective drying of whole bananas. The experiments were carried out with drying air temperatures at 40, 50, 60 and 70 degrees C. A two-dimensional numerical solution in generalized coordinates of the diffusion equation with boundary condition of the third kind, obtained through the finite volume method, was used to describe the process. A structured nonorthogonal grid was obtained by digitization of the photography of the fruit. In order to determine the thermo-physical properties, an optimizer was coupled with the numerical solution. The model proposed |
