Mathematical modeling of convective drying: Lumped temperature and spatially distributed moisture in slab

Abstract

The present study describes the modeling and simulation of the drying process. The model considers<br><br>fundamentals of the drying process and takes internal resistance to moisture into account. The main<br><br>connotation of this study regards the possibility of employing a new analytical method for simultaneous<br><br>heat and mass transfer. The proposed model considers the evaporative heat transfer at the surface of<br><br>product. The validation of the model is made with a set of numerical and experimental results reported<br><br>in the literature for carrot sliced in slab form. The results reveal that there is nearly perfect match<br><br>between the temperature and moisture obtained by the analytical model and the numerical solution.
