Description

Yellow water pit wall circulating device Technical Field The utility model relates to the technical field of strong aromatic white spirit brewing equipment, in particular to a yellow water pit wall circulating device. Background Yellow water, also called yellow serofluid, is a fermentation byproduct specific to solid state fermentation of white spirit. In the fermentation process, a microecological system formed by protease, saccharifying enzyme, esterifying enzyme and other enzymes and various microorganisms in distiller's yeast is used for decomposing macromolecular substances such as protein, starch and the like in the brewing raw materials to generate micromolecular components such as reducing sugar, amino acid and the like and various aroma components such as aroma precursor substances, alcohol and the like, and the supersaturated moisture in the fermented grains entering a pool and the moisture generated by aerobic respiration of saccharomycetes are permeated to the bottom of a pit together, so that the formed tan or brown turbid liquid with special smell is yellow water. Yellow water contains rich substances with fragrance, such as organic acid, higher alcohol, lower fatty acid ethyl esters and the like, and has certain correlation with the formation of characteristic fragrance of strong aromatic white spirit, so Huang Shuibei is considered as a high-quality raw material for developing brewing resources. Meanwhile, the yellow water plays an important role in maintaining the mutual relation between pit mud bacterial groups and fermented grains bacterial groups, bacterial groups in the yellow water can infiltrate into pit mud along with the yellow water to influence the pit mud bacterial groups, and anaerobic bacteria with flagella in the pit mud bacterial groups can enter the fermented grains along with the yellow water to influence the fermented grains bacterial groups, such as clostridium, rumen bacteria and the like. Meanwhile, the yellow water is high in acid and anaerobic in special environment and rich in nutrient components derived from fermented grains and pit mud, so that the yellow water can be used as a natural screening culture medium to provide a favorable growth environment for brewing and aroma-producing flora in white spirit fermentation, a special micro-ecological system is formed, and the yellow water plays an important role in ageing and maintenance of the pit mud. Therefore, yellow water is also called as 'high-quality liquid pit mud', and is an executor of 'perpetual vintage'. In the same strong aromatic pit, because of the unidirectional flow and aggregation of yellow water from top to bottom, the quality of white spirit produced by the bottom fermented grains is obviously superior to that of the upper fermented grains, and simultaneously the aging speed and quality of pit mud at the lower part of the pit are also obviously superior to those of pit mud at the upper part. At present, on the premise of unchanged basic process and yield, how to improve the quality of upper-layer wine and how to accelerate the aging of pit mud in a new pit is two common technical problems in the whole white spirit industry. The existing yellow water circulation equipment is characterized in that yellow water at the bottom is directly poured into fermented grains from the top of the fermented grains, and macromolecular organic acid, mud odor and water-soluble impurities in the yellow water can seriously influence the quality of the fermented grains, so that the defect is quite obvious. Therefore, a yellow water pit wall circulating device is provided. Disclosure of utility model It is an object of the present utility model to provide a yellow water pit wall circulation device that solves or at least alleviates one or more of the above-mentioned and other problems of the prior art. In order to achieve the above purpose, the main technical scheme adopted by the utility model comprises the following steps: The yellow water pit wall circulating device comprises a pit wall sprayer, wherein the pit wall sprayer comprises an annular pipe, and the bottom of the annular pipe is communicated with a plurality of spraying pipes for spraying to the inner wall of a pit; The collecting tank is arranged at the bottom of the pit, and the upper end of the collecting tank is communicated with the inner bottom of the pit; The liquid inlet of the water pump is communicated with the lower end of the interior of the collecting tank through a first pipe fitting, and the liquid outlet of the water pump is communicated with the liquid inlet of the cellar wall sprayer through a second pipe fitting. In the yellow water pit wall circulating device, the annular pipe is a square annular pipe, two liquid inlet pipes are communicated with the annular pipe, and the two liquid inlet pipes are distributed at the top of the diagonal part of the annular pipe. According to the yellow water pit wall circulating device, the spraying pipe com
