Verification of a novel Thin-Layer Drying Mathematical Model of air Dried Mint leaves

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 (R2) values were chosen as the best models. According to this, the introduced model showed the best coefficient of correlation for all of temperatures.
