Abstract
The best drying conditions can be selected by using mathematical modeling of herb drying processes. Development of mathematical models for drying Centella asiatica leaves is the major goal of the current study. At temperatures of drying of 50, 55, and 60 C, the drying behavior of Centella asiatica leaves was examined. The drying data were fitted to the eight thin-layer models. Non-linear regression evaluates the accuracy with which validated mathematical models fit the data. By evaluating R2, reduced chi-square, and RMSE between the observed and predicted moisture ratios, the performance of various models was evaluated. The analysis of the drying curve of Cetella asiatica leaves revealed that the Midilli-Kucuk model was the most. accurate.
