A constant level of air flow rate of 0.087 m 3 s -1 was used and constant dimensions for tilapia fillets of 80 x 30 x 5 mm of length, width and thickness respectively. Seven different widely used thin layer drying models were fitted to the experimental drying data of fresh tilapia fillets under different conditions using nonlinear fitting techniques. Four statistical parameters, including coefficient of determination, standard error, reduced chi-square, and root mean square error, were used to compare all models. The obtained results showed that the drying process took place in falling rate periods. The result also showed that average value of determination coefficient in exponential linear combination model was 0.9988, and standard error, root mean square error and corresponding reduced chi-square values were 0.106, 0.0096 and 0.0001, respectively, which indicated that “exponential linear combination model” is the best of studied models for describing drying curves of fresh tilapia fillets.

The drier was also equipped with three axial flow fans to supply air over the samples to carry the evaporated moisture. The passing air was adjusted at three different temperatures (40, 50 and 60 o C) and constant air velocity of 2 m/s.
