Baijiu fermenting tank and building method

Abstract

The invention discloses a baijiu fermenting tank and a building method. The problems that for a general fermentation pit, pit mud is prone to aging, and for a returned mud fermentation method, due to the fact that the mud quantity in fermented grains is too large, distillation is affected are solved. The baijiu fermenting tank comprises a fermentation pit, a pit cover, a pit cavity, a waterproof layer, a fermentation pit liquid containing interlayer, a yellow water tank and a U-shaped tube, the fermentation pit is internally provided with a pit mud permeable barrier, the portion between the pit mud permeable barrier and the inner wall of the fermentation pit is the fermentation pit liquid containing interlayer which is shaped like an inverted truncated triangular pyramid, and a pit edge seal ring is arranged on the top of the fermentation pit liquid containing interlayer. According to the fermenting tank, the pit mud is rich in a large amount of beneficial microbiota, and generation of aroma-producing substances of distiller's grains is increased; a functional bacteria culture solution is added into a pit cover liquid containing cavity and the fermentation pit liquid containing interlayer, after a main fermentation period is completed, the functional bacteria culture solution permeates the distiller's grains through the permeable barrier, a biochemical reaction of generating ester from acid and alcohol is completed, the content of aroma-producing ingredients of strong-flavor baijiu is further increased, and a baijiu body style is highlighted.

Description

technical field [0001] The invention belongs to the field of liquor brewing, and in particular relates to a cellar for liquor fermentation. Background technique [0002] Most of the existing fermentation tanks are made by digging a square pit on the ground. The cellar pool generally consists of a cellar cavity, a waterproof layer, and a cellar wall. When mature, the cellar wall is formed by attaching bamboo sticks to the waterproof layer. At the same time, a yellow water layer is set up at the bottom of the pool (separating the grain grains from the yellow water). As the grain grains are fermented, the height of the grain grains will decrease with the passage of fermentation time, causing the upper cellar wall to lose moisture without grain grains, resulting in the loss of activity or death of microorganisms in the pit mud. A large number of microorganisms in the pit mud seep into the yellow water with the yellow water, causing the pit mud to age. At the same time, due to...
