The invention discloses a laminate film-forming aerobic
fermentation tank, which comprises a tank body, a top cover, a laminate, a baffle plate, a baffle plate with a hole at bottom, an overflowing plate, a flow
guide tube, a
feeding tube, an exhaust tube, an air inlet tube, an air exhaust tube, an air supply
system, a
feed pump and an on-line acidity detection apparatus. The invention also discloses a
fermentation method of the laminate film-forming aerobic
fermentation tank. In the invention, the technical problems of large floor area, low fermentation efficiency, noncontinuous production, difficult
fermentation condition control, instable product quality and poor product
flavor of the prior air are solved. The fermentation tank and the fermentation method have the characteristics of ensuring the integrity of bacterial membrane in fermentation liquor, increasing dissolved
oxygen, retaining high product
flavor, along with small floor area, high yield, short fermentation period,
continuous production, stable equipment operation, stable and controllable quality, convenience for cleaning and the like.
