Description

Solid-state fermentation pit helpful for improving quality of liquor produced from strong aromatic white liquor

Technical Field

The utility model relates to a making wine technical field specifically is a solid state fermentation jiao chi that helps improving strong aromatic white spirit and produce wine quality.

Background

The strong aromatic white spirit has high sale share in the white spirit market, is the most common type of the aromatic white spirit, is mainly distributed in Sichuan, Sulu Yu Wan and other areas, and has important influence on the development of the white spirit industry on the yield and quality. The main body fragrance ethyl caproate of the strong aromatic Chinese spirits is prepared by esterification reaction of caproic acid generated by caproic acid bacteria and ethanol generated in the fermentation process, and the caproic acid bacteria is used as an important functional microorganism in pit mud and plays an important role in forming the flavor of the strong aromatic Chinese spirits. The quality of the pit mud affects the quality of the strong aromatic Chinese spirits, and the quality of the pit mud not only depends on the physical and chemical indexes of the pit mud, but also depends on the types and the quantity of the beneficial pit mud functional bacteria in the pit mud, the metabolic capacity of the products and the reasonable proportion of the nutrient components. The quality of making of strong aromatic white spirit and the ageing and the maintenance of cellar mud are directly related to the excellence of cellar pool building, and traditional cellar pool that strong aromatic white spirit made and used, its defect and drawback mainly have: in the production process of the Luzhou-flavor liquor, the phenomena of pit mud falling and aging often occur in a pit, pit mud falling and mixing into fermented grains can cause mud odor of pit mud to be brought into the liquor during liquor distillation, and the quality and style of the Luzhou-flavor liquor are seriously influenced; the problems of breakage or collapse and the like of the pit wall between the adjacent pit pools exist, the yellow serofluid of the adjacent pit pools is communicated or underground water permeates into the pit pools to influence sealed fermentation and the like; the contact area of pit mud and grain mash is limited, the maintenance of pit mud, especially the maintenance of pit mud on the pool wall is complicated and difficult, and in the process of maintaining the pool wall by using caproic acid bacterial liquid, due to factors such as unreasonable slope design of the pool wall and the like, the caproic acid bacterial liquid is easy to cause over-fast downward flowing and cannot well permeate into the pit mud on the pool wall.

Chinese utility model patent CN 105695299B proposes a strong aromatic white spirit fermentation cellar and building method thereof, the material of cellar for storing things pond is regarded as to the stereoplasm brick that has open-top pit in the cellar for storing things pond, is equipped with the cavity in the wall brick, and all splendid attire has the cellar for storing things mud in the pit of stereoplasm brick and the cavity. This kind of strong aromatic white spirit fermentation jiao chi can reduce and play in a wretched state when playing in a wretched state instrument and operating personnel to the destruction and the damage of cellar for storing things mud, but the setting of stereoplasm brick has reduced the thickness of bottom of the pool cellar for storing things mud and the area that contacts with the grain unstrained spirits, is unfavorable for the adherence of cellar for storing things mud microorganism and inhabits and flourishes etc. has certain negative effects to the improvement of producing wine quality.

Chinese utility model patent CN102807949A discloses an ecological aromatic type daqu wine cellar of making, the cellar for storing things wall lacing wire is selected to use the bamboo to construct in characterized by cellar for storing things pond, and the environmental protection is safe corrosion-resistant, and the cellar for storing things wall of building is difficult for collapsing, is favorable to the growth of cellar for storing things mud microorganism and cellar for storing things mud mature. The utility model discloses a cellar for storing things pond compares some adjustments with traditional cellar for storing things pond in the aspect of the pool wall slope, but, the inside grain unstrained spirits of the cellar for storing things pond of this cellar for storing things pond still is limited with the area of contact of cellar for storing things mud, and corresponding processing is not done in building of pool wall, still exists the pool wall cellar for storing things mud of cellar for storing things pond and adheres to and the difficult scheduling problem of maintenance, and does not realize the interior collection etc. of cellar for storing things pond of making wine yellow serofluid. The utility model discloses a select red silt soil, old cellar for storing things bacterial liquid, yellow serofluid, cauda etc. as the mixture, common misce bene makes cellar for storing things wall mud, make the physicochemical environment and the microbial community in newly-built cellar for storing things pond reach old cellar for storing things pond level, make newly-built cellar for storing things pond be old and mature fast in the short time, though adopt the bamboo as cellar for storing things wall lacing wire, but the intensity and the infiltration scheduling problem of pool wall do not solve between the adjacent cellar for storing things pond, probably there is the collusion of yellow serofluid between the adjacent cellar for storing things pond, lead to the scheduling problem that collapses of cellar for storing things wall.
