Vacuum decompression fermentation system for probiotic fermentation

Abstract

The invention relates to the technical field of biological fermentation, and discloses a vacuum decompression fermentation system for probiotic fermentation, the upper end of a fermentation tank close to the left side of a stirring mechanism is respectively connected with a nitrogen cylinder and a vacuum pump from front to back, and the upper end of the fermentation tank close to the right side of the stirring mechanism is respectively connected with a feeding mechanism and a pressure gauge from front to back; a heating mechanism is mounted at the front end of the outer side of the fermentation tank in an embedded manner. Fermentation liquid in the fermentation tank is stirred through the stirring mechanism, the distance between the dispersing assembly and the center of the fermentation tank can be adjusted through the distance adjusting frame in the stirring mechanism, so that stirring can be conducted in different ranges, the dispersing assembly can also stir and disperse the fermentation liquid, and the stirring effect is improved; liquid added into the fermentation tank can be preliminarily dispersed during feeding through the dispersion disc assembly, so that subsequent stirring is facilitated, the stirring blades can be protected through the protective cover, and the safety of the fermentation system is improved.

Description

technical field [0001] The invention relates to the technical field of biological fermentation, in particular to a vacuum decompression fermentation system for probiotic fermentation. Background technique [0002] Probiotics are a class of microorganisms, acquired microorganisms that, when taken in sufficient quantities, will have a beneficial effect on human health. Lactic acid bacteria is a general term for a class of microorganisms that can ferment carbohydrates to produce large amounts of lactic acid; a part of lactic acid bacteria are probiotics. Common probiotics include bifidobacteria, lactobacilli, and probiotic streptococci. Probiotics and their fermented products have a variety of physiological functions. Among them, the fermentation process of probiotics is one of the most important ways to increase the number of viable bacteria in fermented milk. [0003] The Chinese patent discloses a normal temperature vacuum decompression fermentation probiotic fermentation ...

AI Technical Summary

Problems solved by technology

[0003] The Chinese patent discloses a probiotic fermenter for vacuum and decompression fermentation at normal temperature (authorized announcement number CN111154617A). The telescopic rod drives one end of the body to shake up and down, so that the probiotics can fully contact and mix with the material. Through the setting of the oxygen exhaust port, vacuum pump and hose, the vacuum pump can transfer the oxygen in the inner cavity of the body through the connection between the oxygen exhaust port and the hose. Suction, the effect of vacuum fermentation, through the setting of the motor, stirring rod and stirring blade, the effect of automatic mixing of probiotics and materials is achieved, but the stirring range is small, and it cannot effectively mix various materials evenly. And the stirring device cannot be protected, which may easily cause damage to the inside of the fermenter
