Fermentation tank, equipment system for preparing probiotics and method for preparing probiotics

Abstract

The invention discloses a fermentation tank, an equipment system for preparing probiotics and a method for preparing probiotics. The motor of the fermentation tank is positioned under a tank body, and facilitates convenient tank opening cleaning as well as scale removing through magnetic stirring. The equipment system for preparing probiotics comprises the fermentation tank, a filtering device, afreeze-drying device, a comminuter, and a stirrer. Specifically, the filtering device is added with a heat exchanger, employs a ceramic membrane prepared from an inorganic ceramic material by a special technology, and can reach the purposes of separation, concentration and purification by means of crossflow filtration and pressure driving during using; and the freeze-drying device consists of a cryogenic refrigerator and a freeze dryer, the temperature sensor of which is fixed on the sidewall of a material plate. During preparing probiotics, the material freezing step undergoes in the cryogenic refrigerator, and the material drying process undergoes in the freeze dryer, thus reducing energy consumption and improving production efficiency.

Description

technical field [0001] The invention relates to a fermenter, an equipment system and a method for preparing probiotics. Background technique [0002] Probiotics refer to microorganisms that have medical and health effects on human and animal bodies by improving the balance of microorganisms and enzymes in the body, stimulating specific or non-specific immune mechanisms. [0003] At present, there are two main production processes of probiotic products, namely solid fermentation method and large tank liquid submerged fermentation method. The solid fermentation method is a fermentation method in which probiotics are inoculated on a solid medium for fermentation and cultivation. At present, most probiotic products in my country use this production method; its advantages are relatively extensive management, simple production process, and low investment. characteristics, but at the same time, it has the disadvantages of being easily polluted by miscellaneous bacteria, the content...

AI Technical Summary

Problems solved by technology

However, the freeze dryer is more expensive and consumes more energy during the drying process, so the processing cost is higher

[0010] When pulverizing the material obtained after freeze-drying, the pulverizer used in the existing pulverization process has the problem of uneven particle size after pulverization, so that high-activity bacteria cannot be fully screened out in the next sieving process, greatly reduced productivity

[0011] When diluting and mixing the pulverized and sieved materials, the existing technology adopts the method of spiral stirring, which has the problem of uneven mixing of materials, resulting in the loss of some viable bacteria, which affects the final yield, and the cleaning of the propeller blades is also troublesome.
