Abstract

In this study we have elucidated the suitable drying model for the far infrared drying of taegeuk ginseng. Thin layer drying tests of taegeuk ginseng were conducted at 3 temperature levels of 45, 55, and 65°C, and 3 taegeuk ginseng size levels of large, medium, and small. Four thin layer drying models were used to estimate drying curves. The goodness-of-fit of the drying models were evaluated using the coefficient of determination (R2), root mean square error (RMSE), mean relative deviation modulus (Pe), and reduced chi-square (χ2). In the mean time, the influences of drying temperature and taegeuk ginseng size on drying behavior were also determined. The results revealed that the Page model, which can describe the far infrared drying behavior of taegeuk ginseng with a great accuracy, was the best model to fit adequately most of the drying conditions for the far infrared drying of taegeuk ginseng.
