**Publication abstract:** For determination of drying kinetics of Thompson seedless grapes a suitable experimental
unit for online measurement was designed and fabricated. The drying characteristics of oil
emulsion pretreated grapes were measured using ambient air under controlled air
temperatures (50 to 80ºC) and velocity (0.25 to 1.00 m/s) conditions. Out of the three models
considered (Page’s, Single term and Two term exponential) Page’s model was found to be
the most suitable for describing the drying behaviour of the grapes. The dependence of drying
constant K of the Page’s model on process variables (Temperature and Velocity of Air) was
analyzed using Arrhenius and Power Equations. It was found that the Arrhenius Equation
gives better values of K than the Power Equation. It is also found that the dependence of
another drying constant N of the Page’s equation on the process variables can not be
described in terms of Arrhenius or power Equations.
