Abstract :
    Mentha leaves were dried in hot-air drying using 3 different air temperatures (60, 70 and 80°C) with velocity of 1 m/s. In this study, measured values were compared with predicted values obtained from twenty one thin layer drying theoretical/ semi empirical/ empirical equations. Also a novel model of kinetics of thin layer drying is tested in this study. Models with highest coefficient of correlation (R^2) values were chosen as the best models. According to this, the introduced model showed the best coefficient of correlation for all of temperatures.
