The invention relates to a
system and a method capable of preventing
microbiological contamination during
inoculation of microbial
fermentation, belonging to the technical field of microbial
fermentation. The
system comprises an inoculating
bottle and a
fermentation tank, wherein a rubber plug is arranged in the
bottleneck of the inoculating
bottle, a first through hole is formed in the middle ofthe rubber plug, a gland is arranged at the outer side of the
bottleneck, the gland tightly presses the rubber plug into the
bottleneck, and a second through hole concentric with the first through hole is arranged in the middle of the gland; the fermentation tank comprises a tank body and a sealing cover arranged on the tank body, a material supplementing
pipe is arranged on the sealing cover, a material supplementing valve is arranged on the material supplementing
pipe, a first short joint and a second short joint connected in sequence are arranged between the material supplementing valve andthe sealing cover, an inoculating valve is arranged between the first short joint and the second short joint, a latex hose sleeves the
tail end of the second short joint, an
insertion head made of astainless
steel tube sleeves the
tail end of the latex hose, the
insertion head made of the stainless
steel tube is inserted in the first through hole and the second through hole, and an emptying valve is further arranged on the sealing cover. With the
system and the method provided by the invention, the problem that
microbiological contamination easily occurs during
inoculation of microbial fermentation can be solved.
