Abstract :In this study, the drying characteristics of okra were determined at the different air temperatures and air velocity. In the experiments, air temperatures and air velocities as parameters were used at 40 oC, 50 oC, 60 oC, 70 oC and 1 m/s, 2 m/s, respectively. The data obtained were evaluated with STATISTICA statistical program. Increasing of air temperature and air velocity was caused to increase of drying velocity on okra. As a result of Newton Model, Root Mean Square Error insert ignore into journalissuearticles values(RMSE); values between 0.011318 and 0.025491, chi square values insert ignore into journalissuearticles values(X2); between 0.000131 and 0.000109, and the modeling efficiency insert ignore into journalissuearticles values(EF); values between 0.998841 and 0.989590 were determined. Also in the Page Model, RMSE, X2 and EF values changed between 0.002414 and 0.012642, 0.000005 and 0.000183, and 0.998127 and 0.999929, respectively.
