Abstract:

Thin layer drying behaviour of mint leaves was investigated in axial flow tray dryer at air temperatures of 45, 55 and 65°C. Five different thin layer drying models namely Newton, Page, Logarithmic, Diffusion approach and Henderson and Pabis models were fitted to experimental drying data. The highest adjusted R2 with the lowest standard square error (SSE) and root mean square error (RMSE) were selected as statistical criteria to evaluate how well the tested models fit the drying data. Diffusion approach model was considered to be satisfactory to represent the thin layer drying of mint leaves. Moisture diffusivity values were varied from 3.29×10-10 to 6.03×10-10 m2/s. The temperature dependent activation energy (Ea) was determined as 16.90 and 12.85 kJ/mol for control and blanched sample.
