Zingiber Roscoe (Ginger) Drying Kinetics and Statistical Examination

— This investigation has studied the drying kinetics of Zingiber Roscoe (ginger) with respect to moisture ratio vs. drying time and found that the temperature effect (33oC, 43oC, and 53oC) is more dominant than air velocity (1 m/s, 2 m/s, and 3 m/s). The drying rate of ginger has revealed substantial feature related to surface free water removal and bound water in material core. This study has also investigated the modeling of drying kinetics, i.e. the Newton, Page and Henderson-Pabis models. The results show that the Page modeling is the best fit model on the basis of statistical parameters, i.e. the R2 (coefficient of determinant), RMSE (root mean square error), and χ2 (chi-square). The Page modeling shows R2 value nearest to unity and lowest values of both RMSE and χ2 for all given temperatures (33oC, 43oC, and 53oC) and air velocities (1 m/s, 2 m/s, and 3 m/s)
