Abstract: The drying characteristics of ginger slices were compared with the different drying temperature and thickness by drawing drying curve by changing the moisture in the drying process of ginger slices. The results showed that the higher the drying temperature, the faster the rate of drying ginger, and the entire drying process in a falling rate drying stage. When the slice thickness is 2 mm and the drying temperature is 60 ℃, the drying rate and Deff are better, which is suitable for practical production.
