The invention discloses a packing tower type continuous surface fermentation device which comprises a packing tower, a filler material, a plurality of partition boards, an air inlet, an air outlet, a blower, a first recirculation pump, a second recirculation pump, a feed valve, a discharging valve, an outlet valve, an inlet valve, an on-line acidity detecting instrument and a collecting tank. The invention further provides an implementation method of the packing tower type continuous surface fermentation device. According to the invention, the problems of difficulty in protecting the integrity of bacterial fibrous membrane, large occupied area, long fermentation time, high labor intensity, incapability of carrying out favorable fermentation parameter control and continuous automatic production and the like in the conventional surface fermentation technology, and is characterized in that the structure is simple, the operation is easy, the production period is short, the product quality is excellent, raw material supply is convenient, the bacterial fibrous membrane can be kept perfectly, and fermentation liquor is in effective contact with the bacterial fibrous membrane.
