“…Sahin et al (2002) developed an analytical method for the determination of drying time of multi-dimensional products. Sahin and Dincer (2005) developed a new analytical method for predicting drying times of irregular shaped multi-dimensional moist solids. Ruiz-López and Garcia-Alvarado (2007) proposed a model that provides a simple mathematical description for food drying kinetics and considered both shrinkage and a moisture dependent diffusivity.…”

The effects of different drying temperatures on the drying kinetics of tomato slices were investigated using a cabinet-type dryer. The experimental drying data were fitted best to the to the Page and Modified Page models apart from other theoretical models to predict the drying kinetics. The effective moisture diffusivities varied from 1.015 9 10 -9 to 2.650 9 10 -9 m 2 s -1 over the temperature range studied, and activation energy was 22.981 kJ mol -1 .List of symbols a, b, c, n Constants of models k, k 0 , k 1 Rate constants in models, h -1 MR Moisture ratio D eff Effective diffusivity (m 2 s -1 ) D 0Pre-exponential factor of the Arrhenius equation (m 2 s -1 ) E a Activation energy (kJ mol -1 ) LHalf-thickness of the slab in samples, m M t Moisture content, g water/g dry matter M e Equilibrium moisture content, g water/g dry matter M 0
