The thin-layer drying behavior of vegetable wastes (as a mix of lettuce and cauliflower leaves) from wholesale market for a temperature range of 50--150 C was determined. Drying of this material was found to take part only in the falling-rate period. The experimental data were fitted to the simple exponential model and the Page model. Both models have good prediction capability. Effective diffusion coefficient varied from 6.03 x 10{sup {minus}9} to 3.15 x 10{sup {minus}8} m{sup 2}/s with an activation energy of diffusion of 19.82 kJ/mol. The temperature dependence of the effective diffusion coefficient was expressed by an Arrhenius-type relationship.
