In the present work, the effects of some parametric
values on the thin layer drying process of ginger slices were investigated.
Drying was done in the laboratory by using cyclone type convective dryer.  The drying air temperature was varied as 40,
50, 60 and 70 ˚C and the air velocity is 0.8, 1.5 and 3 m/s. All drying
experiments had only falling rate period. The drying data were fitted to the
twelve mathematical models and performance of these models was investigated by
comparing the determination of coefficient (R2), reduced chi-square (χ2) and
root mean square error (RMSE) between the observed and predicted moisture
ratios. Among these models, drying model developed by Midilli and Kucuk model
showed good agreement with the data obtained from the experiments.
