Brewer's Yeast Rapid Fermentation Method and Its Application

Abstract

The invention relates to a rapid fermenting method of beer yeast and its application, belonging to the technical field of beer brewing technology. The method comprises the following steps: pre-expansion: the yeast is subjected to primary expansion and secondary expansion in sequence; third-level expansion: adding nutrient-enhanced wort during the third-level expansion, and when the yeast in the expansion solution reaches 40 When the temperature is 80 million / ml, the temperature is lowered to -2-5°C, and the expansion medium is refrigerated for use; for expansion and use: activate the above-mentioned yeast in the refrigerated expansion medium for use; starting fermentation production: the above-mentioned activated yeast The expansion liquid is mixed with the expansion wort, and enters the fermentation tank for starting fermentation production. The above-mentioned rapid fermentation method for brewer's yeast, by adding nutritionally enhanced wort during the expansion of the three-stage expansion tank, and strictly controlling the growth of the number of yeast during the expansion of the three-stage tank; The activation treatment ensures the activity of the yeast after large-scale production, thus effectively solving the problems of easy performance degradation and short storage time of yeast in the workshop.

Description

technical field [0001] The invention relates to the technical field of beer brewing technology, in particular to a rapid fermentation method for brewer's yeast and its application. Background technique [0002] In the daily production process of the beer industry, there will be a shortage of yeast, especially in the peak production season, there will be a temporary increase in the production plan or other reasons resulting in a shortage of yeast in the workshop, which will affect the smooth completion of the production plan and even cause the market to be out of stock. [0003] When there is a shortage of yeast in the workshop, if the expansion of yeast is restarted, it needs to be expanded from the test tube stage in the laboratory, and it will take about 8 to 9 days to expand to the fermenter, which will affect production and market supply; Eliminated high-generation yeast or abnormal yeast production will adversely affect the flavor quality of beer because the yeast perfo...

Problems solved by technology

[0004] Based on this, it is necessary to address the above problems and provide a rapid fermentation method for beer yeast, which can realize rapid fermentation and effectively solve the problem of beer quality caused by the continuous use of high-generation yeast or abnormal yeast in the production of original beer enterprises when yeast is in short supply. Adverse effects, not only to ensure product quality, but also to ensure the normal supply of the market
