Method for preparing probiotics

Abstract

The invention discloses a method for preparing probiotics. An equipment system for preparing probiotics used by the preparation method comprises a fermentation tank, a filter device, a freeze-drying device, a pulverizator and a stirrer, wherein the freeze-drying device comprises a cryogenic refrigerator and a freeze dryer; a temperature sensor of the freeze dryer is fixed on the lateral wall of a material tray, and positioned at the middle position in the up-and-down direction of the lateral wall of the material tray; a probe end of the temperature sensor is arranged inside the material tray; one end, facing to the outer side of the material tray, of the temperature sensor is connected with a cable; the other end of the cable is connected with a cable joint and then connected with a joint of a temperature measurement and control system of the freeze dryer. The preparation method comprises the steps of preparing a culture solution, sterilizing, inoculating, filtering and concentrating, carrying out freeze drying, crushing and mixing. The freezing step of the material is carried out in the cryogenic refrigerator when the probiotics are prepared while the drying process of the material is carried out in the freeze-drying device, so that energy consumption is reduced; the production efficiency is improved.

Description

[0001] This application is a divisional application of the invention patent application with the application number 201110459650.9 and the application date is December 31, 2011, and the invention name is "fermentation tank, equipment system for preparing probiotics and method for preparing probiotics". technical field [0002] The invention relates to a method for preparing probiotics. Background technique [0003] 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. [0004] 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...

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

[0011] 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 the highly active bacteria cannot be fully screened out in the next sieving process, which greatly reduced productivity

[0012] When diluting and mixing the pulverized and sieved materials, the existing process adopts the method of spiral stirring, which has the problem of uneven stirring of the materials, resulting in the loss of some viable bacteria, which affects the final yield, and the cleaning of the propeller blades is also troublesome.
