The invention provided a secondary-
fermentation black tea as well as a production method and a production device thereof. The process comprises the following steps: (1) picking up fresh tea leaves, inactivating the fresh tea leaves, spreading the fresh tea leaves for cooling so as to enable the
water content of the tea leaves to be 50-60%, rolling and
curling the fresh tea leaves into a strip shape, deblocking the tea leaves after rolling,
drying the tea leaves so as to enable the
water content of the tea leaves to be 88-90%, and then piling, dismissing and sifting so as to obtain primary-
fermentation black tea leaves; (2) putting the primary-
fermentation black tea leaves on pallets and brackets, placing the brackets in a fermenting room, providing steam so as to fill the steam among the tea leaves at a temperature which is controlled at 50-60 DEG C for 5-15 hours, and then stopping providing the steam, fermenting the tea leaves for 3-7 days in the sealed fermenting room, and after fermenting, performing airing, natural cooling and
drying so as to obtain secondary-fermentation black teat products. By virtue of twice fermentation, the black tea is clean and sanitary, is high in quality, is uniform in tea color, is better in quality, is fragrant in smell after being soaked in water, is savoury and mellow, has multiple health functions for a
human body and is a treasure in whole-
fermented tea.
