Abstract

Drying using a hot air chamber was tested on samples of belimbing dayak fruit (Baccaurea angulata). The drying experiments were performed at various air temperature drying (40 to 50oC). Drying kinetics of belimbing dayak fruit were investigated and obtained. Ten drying models were compared with experiments data belimbing dayak fruit drying. A new model was introduced, which is an offset linear logarithmic (offset modified Page model). The fit quality of the models was evaluated using the coefficient of determination (R2), Root Mean Square Error (RMSE) and Sum of Squared Absolute Error (SSAE). The result showed that the new model was comparable with two or three-term exponential drying models.
