The application belongs to the technical field of enzymology or
microbiology devices, and particularly relates to a
fermentation device for dry
choking yogurt production, which comprises a
fermentation tank, a connecting shell is fixed at the top end of the
fermentation tank, a speed
reducer motor is installed at the top end of the connecting shell, a feeding port is fixed at one side of the top end of the fermentation tank, an inner container is arranged in the fermentation tank, a plurality of micropores are arranged at equal intervals on the outer side of the inner container, a liquid
discharge pipe is fixed at one side of the bottom end of the fermentation tank, and a
discharge port is arranged at the bottom end of the fermentation tank; a stirring rod is arranged in the inner container, a plurality of connecting blocks are fixed to the outer side of the stirring rod, and a plurality of blades are rotatably connected to the outer side of the connecting blocks; the base material,
streptococcus thermophilus and
lactobacillus bulgaricus are fully mixed through the blades,
lactobacillus bulgaricus secretes
protease to perform enzymolysis on
casein to form a gel network, the blade structure is matched with the lifting adjusting
assembly, bidirectional material stirring of the base material can be realized without changing the stirring driving motor, and the mixing uniformity of the base material and the strains is improved.
