| Abstract: | Bamboo shoots were dried with hot pump device to detect the effects of temperature, cutting thickness and pretreatments on the drying characteristics and the product rehydrating rates. Rapid drying and high quality were obtained in the bamboo shoots of thinner cut with preheating and high temperature, and high rehydrating rates were obtained in the products of thinner cut with high temperature and no preheating. When Logistic curve was used to coincide with the state distribution of the change of bamboo shoot water content along with the drying duration and power function was used to coincide with the state distribution of product rehydrating rates, decision coefficients ( r 2) were over 0.9725 and 0.9610, respectively. |
