Page model has been found to describe the kinetics of thin-layer drying of sweet potato slices
between 50oC and 80oC in a tray dryer. The two-term and logarithmic models displayed superior
correlation to rest five models. The time for achieving equilibrium moisture content was observed to
increase with thickness and mass of the slices and decrease with drying temperature. Blanching of the
sweet potato slices enhanced the drying rate. The quality of dried sweet potato as reflected by rehydration
ratios indicated that structure destruction increased with temperature. However, the
qualities of the dried slices were found to be good.
