Osmotic dehydration and convective drying of coconut slices: Experimental determination and description using one-dimensional diffusion model

Wilton Pereira da Silva [et al.] - Nama Orang;

Mass migrations in coconut slices during osmotic dehydration and drying are described using a diffusion model with boundary condition of the third kind. The osmotic dehydration experiment was performed at 35Brix (water and sucrose) and 40 C. The convective drying experiments were performed at 50, 60 and 70 C. The one-dimensional solution of the diffusion equation for an infinite slab was coupled with an optimizer to determine the effective mass diffusivities D and convective mass transfer coefficients h of the five processes studied. The analyses of the obtained results
indicate that there is a good agreement between each experimental dataset and the corresponding simulation using D and h determined by optimization.
