Technical Field

The invention relates to a dairy product brewing fermentation system, and belongs to the technical field of dairy product preparation.

Background

The existing yoghourt fermentation equipment is a constant-temperature water bath kettle, and the specific process is as follows: sterilizing the inner container and the inner cover with boiled water, cooling, adding the bacteria powder and pure milk, stirring, covering the inner container with the inner cover, and placing into a water bath kettle. And adding water into the water bath kettle until the inner container is immersed into the water bath kettle, and fermenting at constant temperature for a certain time, so that the dairy product in the inner container is subjected to anaerobic fermentation to form the yoghourt. The existing yoghourt equipment has the following problems: (1) the cleaning work is required for each use, the disinfection of the fermentation vessel (inner container) only can be carried out by boiled water, and the effect is only disinfection, so that the sterilization cannot be carried out. (2) Dairy products need to be poured into a fermentation container from an aseptic package, and contact with air and the inner wall of the container, so that mixed bacteria pollution can be caused, and harmful substances can be generated due to mass propagation of harmful bacteria; and meanwhile, the shelf life of the prepared yoghourt is reduced. And (3) if the lactic acid bacteria fermented milk product consumes the lactose contained in the milk product, the fermentation process is very slow. Since a longer fermentation period would greatly increase the risk of contamination with infectious microbes, additional sucrose addition is required. In the prior art, a user adds cane sugar before fermentation, the addition amount is difficult to control, and the fermentation effect is influenced by excess or deficiency and even uneven dissolving and stirring. (4) The fermentation vessel is made of stainless steel, the fermentation vessel cover is made of food-grade plastics, and the fermentation vessel is limited by the requirement of high-temperature cleaning and cannot use rubber materials, so that the fermentation vessel is not tight in sealing, can only keep standing in the fermentation process and is difficult to carry out uniform mixing and stirring operation. (5) At present, the strain used for dairy fermentation is facultative anaerobe, and the fermentation does not need to be communicated with the outside or only needs trace oxygen. The prior art is not tight in sealing, and the risk of mixed bacteria pollution is increased due to excessive oxygen contact.

Another prior art: the powder-liquid separation technology is mostly used for probiotic beverages instead of fermented beverages, and four patents of application numbers 201721677285.8, 201721853875.1, 201822233348.1 and 201180053472.8 disclose a scheme of separating and storing bacteria powder and beverages and mixing the bacteria powder and the beverages during drinking; the scheme solves the problem that the stability and the survival rate of the bacterial powder are seriously reduced under the condition of high water activity, but the dairy fermentation process is not involved; the lactic acid bacteria used in the existing fermentation are facultative anaerobes, and the fermentation does not need to be communicated with the outside or only needs trace oxygen.

The drink and the bacterial powder have poor mouthfeel under the condition of only simple mixing, and meanwhile, the milk drink which is not subjected to the fermentation process has single nutrient component and does not contain abundant zymophyte metabolites in the fermented dairy product. Metabolites generated by fermentation of lactic acid bacteria, such as acid metabolites, exopolysaccharides, lactobacillin, gamma-aminobutyric acid and the like, play an important role in the aspects of regulating intestinal microecology, resisting tumors, regulating immunity, reducing blood cholesterol and the like, and are better in nutrition and functionality compared with a single drinking bacteria powder solution. In addition, single probiotics only act on intestinal flora in a mode of flora inoculation in the digestive tract after oral administration, yogurt is not used as a substrate for protection, and when the probiotics pass through the stomach, the probiotics are directly and quickly dissolved with gastric acid, and the probiotics are easy to inactivate. The milk product fermented by the live bacteria is easy to expire, so that the milk product is over fermented and rotten, the sales range of the milk product fermented by the live bacteria is limited by the coverage range of cold chain logistics, and the shelf life of the milk product fermented by the live bacteria is limited to be less than one week. Meanwhile, the process of self-brewing fermented yoghourt is complicated, the mixed bacteria pollution rate is high, and the selection of self-brewing fermented dairy products of consumers, especially consumers in remote areas, is restricted.
