Abstract:

Several processes in the food industry, such as leaching and drying are usually controlled by internal diffusion. In many cases these processes have been interpreted on the basis of constant diffusion coefficients calculated through a series solution of Fick's second law which converge rapidly for large values of time. This work presents a numerical solution of Fick's second law for various types of concentration dependence of the diffusion coefficient. The results indicate that the above mentioned conventional treatment of experimental data, may not be sufficient to establish whether or not the process is characterized by a constant or variable diffusion coefficient.
