Yeast activation system

Abstract

The invention provides a yeast activation system which comprises an activation tank, a compressed air inlet pipeline, a carbon dioxide inlet pipeline and a yeast output pipeline, and the inside of the activation tank is used for activating yeast; the compressed air inlet pipeline is used for supplying compressed air into the activation tank, and the carbon dioxide inlet pipeline is used for supplying carbon dioxide into the activation tank; the yeast output pipeline is used for being communicated with the fermentation tank so as to convey activated yeast into the fermentation tank. The yeast activation system disclosed by the invention can directly provide activated yeast into the fermentation tank, so that the problems of slow fermentation and poor microorganism control caused by directly putting the yeast into the fermentation tank are avoided. Meanwhile, the activation condition of the yeast in the yeast activation system is controllable, compared with propagation propagation of the yeast, the activation period is short, the activation procedure is simpler, the high activation efficiency of the yeast can be guaranteed, the activation yield can be correspondingly adjusted according to the fermentation requirement, and therefore the requirement for flexibility and variability of different varieties of beer is met.

Description

technical field [0001] The invention relates to the technical field of beer brewing, in particular to a yeast activation system. Background technique [0002] Activation of yeast is the restoration of yeast activity prior to introducing the yeast into the fermenter. Effective activation and protection of yeast in a dormant and dry state is not only a necessary measure for successful yeast activation and inoculation, but also the basis and guarantee for maximizing the potential of yeast to perfectly realize alcoholic fermentation. [0003] With the development of the domestic economy, people's pursuit of beer quality is increasing, and the demand for craft beer continues to grow. Compared with industrial beer, craft beer has less output, but more varieties and flexible styles. The yeast used for industrial beer fermentation is expanded from the laboratory to the expansion system for yeast propagation. The time for expansion and reproduction is long, usually about a week.
