Technical Field
[0001] This utility model relates to the technical field of strong-aroma baijiu brewing equipment, and in particular to a yellow water cellar wall circulation device. Background Technology
[0002] Yellow water, also known as yellow slurry, is a unique fermentation byproduct of solid-state fermentation in baijiu (Chinese liquor). During fermentation, the micro-ecological system composed of various enzymes such as proteases, saccharifying enzymes, and esterifying enzymes, as well as various microorganisms, in the yeast decomposes macromolecules such as proteins and starches in the brewing raw materials, generating small molecular components such as reducing sugars and amino acids, and various aroma components such as aroma precursors and alcohol. Along with the supersaturated water in the mash and the water produced by the aerobic respiration of yeast, this liquid seeps down to the bottom of the fermentation pit, forming a brownish-yellow or turbid liquid with a special odor, which is called yellow water.
[0003] Yellow water contains abundant organic acids, higher alcohols, and lower fatty acid ethyl esters, which contribute to aroma and flavor. These substances are related to the formation of the characteristic aromas of strong-aroma baijiu, thus making yellow water a high-quality raw material for brewing. Simultaneously, yellow water plays a crucial role in maintaining the relationship between the microbial community in the fermentation pit mud and the microbial community in the mash. Microorganisms in the yellow water seep into the pit mud, influencing its microbial community. Conversely, flagellated anaerobic bacteria in the pit mud, such as Clostridium and rumen bacteria, enter the mash along with the yellow water, affecting its microbial community. Furthermore, the highly acidic and anaerobic environment of yellow water, along with its rich nutrients derived from the mash and pit mud, allows it to serve as a natural selection medium, providing a favorable growth environment for the aroma-producing microorganisms during baijiu fermentation. This creates a unique micro-ecological system that plays a vital role in the aging and maintenance of the pit mud. Therefore, yellow water is also known as "high-quality liquid pit mud" and is the executor of the "ten-thousand-year-old mash" process.
[0004] Within the same strong-aroma fermentation pit, the unidirectional flow and accumulation of the yellow water from top to bottom results in a significantly higher quality liquor produced from the bottom layer of mash compared to the top layer. Simultaneously, the aging speed and quality of the pit mud in the lower part of the pit are also significantly better than that in the upper part. Currently, under the premise of unchanged basic processes and output, how to improve the quality of the upper layer of liquor and how to accelerate the aging of the pit mud in new fermentation pits are two common technical challenges for the entire liquor industry. Existing yellow water circulation equipment directly pours the bottom yellow water into the mash from the top. The large-molecule organic acids, muddy odor, and water-soluble impurities in the yellow water severely affect the quality of the liquor, with very obvious drawbacks.
[0005] Therefore, a circulating device for the walls of yellow water cellars is proposed. Utility Model Content
[0006] The purpose of this invention is to provide a yellow water cellar wall circulation device, thereby solving or at least alleviating one or more of the above-mentioned problems and other problems existing in the prior art.

[0027] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0028] Please refer to Figures 1 to 3 As shown, an embodiment of this utility model provides a yellow water cellar wall circulation device, including a cellar wall sprayer 1, a water pump 2, and a collection tank 3;
[0029] Among them, the cellar wall sprayer 1 includes an annular pipe 101, and the bottom of the annular pipe 101 is connected to several spray pipes for spraying onto the inner wall of the cellar 11.
[0030] The collection tank 3 is located at the bottom of the pit 11, and the upper end of the collection tank 3 is connected to the inner bottom of the pit 11.
[0031] The inlet of water pump 2 is connected to the lower end of the inside of collection tank 3 through the first pipe fitting, and the outlet of water pump 2 is connected to the inlet of cellar wall sprayer 1 through the second pipe fitting.
[0032] When in use, the yellow water produced by fermentation in the pit 11 flows naturally into the collection tank 3 at the bottom. The water pump 2 draws the yellow water out of the collection tank 3 through the first pipe fitting, and then transports it to the ring pipe 101 of the pit wall sprayer 1 through the second pipe fitting. It is then sprayed directionally onto the inner wall of the pit 11 through the spray pipe to form a circulation path.
[0033] Among them, water pump 2 is a portable water pump.
[0034] In this embodiment, a filter screen 301 is provided at the upper part of the inside of the collection tank 3.
[0035] When the yellow water in the fermentation pit 11 flows into the collection tank 3, the filter screen 301 intercepts impurities such as mash particles and sediment, preventing them from entering the circulation system and causing pipe blockage or spray nozzle 1041 blockage, thus ensuring the purity of the yellow water and the stability of system operation.
[0036] In this embodiment, the annular tube 101 is a square annular tube, and two liquid inlet conduits 105 are connected to the annular tube 101. The two liquid inlet conduits 105 are distributed at the top of the opposite corner of the annular tube 101.
[0037] The square annular pipe 101 is adapted to the rectangular structure of the pit 11. The diagonally arranged liquid inlet pipes 105 allow yellow water to be injected into the annular pipe 101 from both ends at the same time, forming a counter-flow to ensure that the yellow water is evenly distributed in the annular pipe 101 and avoid uneven spraying caused by uneven local pressure.
[0038] In this embodiment, the spray pipe includes a first outlet pipe 102, a valve 103, and a second outlet pipe 104. The upper end of the first outlet pipe 102 is connected to the lower end of the annular pipe 101. The valve 103 is installed at the lower end of the first outlet pipe 102. The second outlet pipe 104 is connected to the lower end of the valve 103. The bottom of the second outlet pipe 104 is sealed. The side wall of the second outlet pipe 104 is provided with a spray nozzle 1041 facing the inner wall of the pit 11.
[0039] The yellow liquid in the annular pipe 101 flows into the first outlet pipe 102. After the flow rate is adjusted by the valve 103, it enters the second outlet pipe 104. Due to the bottom seal, the yellow liquid can only be sprayed directionally onto the inner wall of the cellar 11 through the spray nozzle 1041 on the side wall, forming a liquid film flowing along the wall surface, thus avoiding direct spraying into the mash.
[0040] In this embodiment, the first pipe includes a first conduit 4 and a second conduit 6. The lower end of the first conduit 4 is connected to the lower end of the inside of the collection tank 3, and the upper end of the second conduit 6 is connected to the inlet of the water pump 2. The second conduit 6 and the first conduit 4 are connected by a first quick connector 5.
[0041] The first quick connector 5 enables quick disconnection between the first conduit 4 and the second conduit 6, facilitating equipment installation and maintenance. After the water pump 2 starts, under negative pressure, the yellow water in the collection tank 3 enters the water pump 2 sequentially through the first conduit 4, the first quick connector 5, and the second conduit 6, completing the yellow water extraction process.
[0042] In this embodiment, the second pipe fitting includes a three-way pipe 7, which is connected to the outlet of the water pump 2. Both outlets of the three-way pipe 7 are connected to a third conduit 8, and the upper end of the inlet conduit 105 is connected to a fourth conduit 9. The third conduit 8 and the fourth conduit 9 are connected to each other through a second quick connector 10.
[0043] The pressurized yellow water from pump 2 is diverted through a three-way pipe 7 to two third conduits 8, and then transported through a second quick connector 10 and a fourth conduit 9 to two inlet conduits 105, finally being injected into the annular pipe 101. This structure, through its dual-channel design, ensures that the yellow water enters the spray system quickly and evenly.
[0044] The above setup also has other functions, such as when yellow water needs to be added, loosening the first quick connector 5, separating the first conduit 4 and the second conduit 6, then inserting the second conduit 6 into the container containing yellow water, starting the water pump 2, thereby realizing the function of adding yellow water to the pit 11.
[0045] When it is necessary to remove all the yellow water from the pit 11, loosen the second quick connector 10 to separate the third conduit 8 and the fourth conduit 9, and then start the water pump 2 to extract all the yellow water concentrated in the collection tank 3 from the pit 11.
[0046] The foregoing description illustrates and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the present invention's conception through the foregoing teachings or related technical or knowledge. Any modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
