Mint leaves are aromatic, almost exclusively perennial, rarely annual, herbs. Drying of mint leaves guarantees a longer shelf time while preserving its quality for use in pharmaceutical and food industries. In this study, the drying behavior of Mint leaves in a fluidized bed dryer (FBD) under different drying conditions (fixed, semi-fluidized and fluidized) and 4 temperature levels (30, 40, 50 and 60 °C) was investigated. The experimental data was assessed using semi-theoretical and experimental models. Finally, Page’s model was selected as the best model based on its R 2 , χ 2 and RMSE values. Findings showed that the effective moisture diffusivity of Mint leaves ranged between 0.91 × 10 –11 and 10.41 × 10 –11 m 2 /s. The activation energy was also between 60.82 and 65.59 kJ/mol. The results of statistical analyses also showed that drying time was significantly reduced with increasing air velocity (changing drying bed from fix bed to fluid bed).
