High-efficiency continuous film-sieving self-suctioning type liquid vinegar fermentation device and process

The invention discloses a high-efficiency continuous film-sieving self-suctioning type liquid vinegar fermentation device and process, and belongs to the field of brewing devices. The high-efficiency continuous film-sieving self-suctioning type liquid vinegar fermentation device comprises a tank body, a cold water pool, a mother liquor sieving circulation pipeline and a wine liquor feeding device. The high-efficiency continuous film-sieving self-suctioning type liquid vinegar fermentation device is characterized in that the tank body is internally provided with a spiral cooling pipe, one end of the spiral cooling pipe is communicated with a cooling water pipe entering the lower part of the tank body, and the other end of the spiral cooling pipe is communicated with a cooling water pipe entering the upper part of the tank body; the cooling water pipe is communicated with the cold water pool to form a cooling water pipeline; the cooling water pipeline is provided with a circulating pump for driving cooling water to circulate; the lower part of the tank body is provided with the mother liquor sieving circulation pipeline to be communicated with the inner part of the tank body; the upper end of the tank body is provided with an air inlet pipe which is internally provided with the wine liquor feeding device; and the lower end of the tank body is provided with a motor for driving a stator and a rotor in the tank body to rotate. The high-efficiency continuous film-sieving self-suctioning type liquid vinegar fermentation device disclosed by the invention has the advantages that the structure is reasonable, the operation is simple, and continuous vinegar discharging and continuous sieving of strong thalli of acetic bacteria are maintained, so that electrical-energy waste at the separation interval is reduced.
