Abstract: In this paper,the characteristics of microwave acing sweet potato were studied.The single-factor experiments were designed to study the effects of different loading quantity,power and thickness of the slice on water content rate,dehydration rate inacing sweet potato.The laws of dehydrating and power consumption were obtained.The mathematical model of microwave drying sweet potato slice was obtained .The experimental results were analyzed by the DPS software,showing the fitting equation with good statistical test results.

Key words: sweet potato(Ipomoea batatas), microwave drying, characteristics, model
