Abstract

Mathematical model of potato slices under process-based temperature and humidity integration control of tilted tray air impingement drying were investigated under different parameters. Results indicated that the Weibull distribution function simulated the drying curves of potato slices under PDTHIC drying well. The coefficient of determination ranged from 0.989 to 0.999, the root mean square error was in the range of 1.04×10-2 to 2.57×10-2, and the derivate square ranged from 1.25×10-4 to 7.15×10-4. The scale parameter α is related to both the humidity control parameters during the earlier stage and the medium stage. The shape parameter β decreased in the range of 0.811~0.964 with the increase of constant humidity, whereas fluctuated in the range of 0.836~0.987 and had no regulations with the changing of the values of humidity control time. The estimated moisture effective diffusivity of potato slices under different drying conditions calculated by scale parameter α ranged from 1.664×10-9m2·s-1 to 2.371×10-9m2·s-1, and the values of geometric parameters Rg was calculated in a fluctuant way in the range of 2.575~5.351.
