Problems solved by technology

At present, the industrial production method of solid culture of probiotics is still limited to static culture and manual stirring, which is manifested by insufficient oxygen supply, high internal temperature of the piled material, uneven temperature, unstable humidity, and serious anaerobic fermentation, etc. conditions, resulting in aerobic probiotics with low viable count and poor activity
Although the number of probiotic spores may reach a certain level in the final product, the yield is not high
In addition, manual mixing of culture materials will lead to passive inhalation of bacterial spores into the respiratory system of operators, causing conditional disease
The accompanying problem is how to quickly dry the culture materials after the aerobic biological fermentation is completed at a lower temperature (≤50°C), which is also the current industrialized production of probiotic solid fermentation and the industrialization of various biopharmaceuticals and food fermentation fields. A big problem facing production

Description

technical field [0001] The invention belongs to the technical field of biological fermentation, and specifically relates to the factory-scale production of aerobic biological fermentation, such as the production of animal microbial feed additives, pharmaceutical biopharmaceuticals, food fermentation production, and related fields of solid fermentation culture production of aerobic flora. Background technique [0002] Probiotics can be made into various functional microbial preparations. The bacteria produced by probiotics during their metabolism are rich in important biologically active substances. As a new type of animal microbial feed additive, it has no toxic side effects, can promote animal growth, increase feed conversion ratio, improve animal digestive tract micro-ecological environment, and enhance animal immunity. From the perspective of bionics, how to cultivate aerobic probiotics with optimized conditions and high-efficiency solids, and how to quickly dry probioti...
