Abstract: Three different drying methods, namely, hot air drying, heat pump drying and heat pump-heat air combined drying, were used to dry the green tea, and the effects of drying methods on the quality of green tea were studied through the determination of vitamin C content of green tea and sensory evaluation. The results showed that the green tea made by heat pump-heat air combined drying was close to the green tea made by traditional heat air drying in sensory, and the green tea made by heat pump-heat air combined drying was close to the green tea made by pure heat pump drying in storage performance.
