Simulation Shrinkage and Stress Generated During Convective Drying of Carrot Slices

Abstract

The moist sample shrinks during drying and the non-uniformity shrinkage involves stresses in the body. The aim of the present work is simulating deformations and drying-induced stresses of carrot slice during a convective drying. The effect of shrinkage on the heat and mass transfer profiles were considered. Non-constant physical and thermal properties were also incorporated in the model and the Experimental conditions were as follows: a drying temperature of 333 K, relative humidity of 11% and air velocity of 1.2 m/s
