Tea fermentation device and fermentation method

The embodiment of the invention discloses a tea fermentation device and a fermentation method. A rolling process and a fermentation process are combined, and multiple cycles of tea between a fermentation cylinder and a rolling disc are realized by virtue of a vibration material disc, so that continuous tea rolling is realized; a barrel-shaped fermentation cylinder is arranged, a water supply pipeand a gas supply pipe are arranged in an interlayer of the fermentation cylinder and are respectively connected to a temperature adjusting apparatus and a humidity adjusting apparatus, accurate control of the tea fermentation process in the inner cavity space of the fermentation cylinder can be realized, and a rolling disc can be driven to descend to cover the upper end of the fermentation cylinder under the driving action of a telescopic motor and a lifting connecting piece, so that implementation of the tea fermentation process is facilitated; meanwhile, a telescopic rod of the telescopic motor drives the fermentati
