Abstract
Description
Technical Field
[0001] This utility model relates to the field of brewing cellars, specifically a structure for collecting and discharging yellow water in a baijiu fermentation workshop. Background Technology
[0002] In traditional solid-state fermentation of baijiu, the collection and discharge of the yellow liquid (rich in fermentation byproducts such as acids and esters) produced at the bottom of the fermentation tank is a crucial step affecting both liquor quality and production efficiency. Current technologies often collect this yellow liquid through pre-buried pipes or by digging pits in the corners of the fermentation tank, which has significant drawbacks.
[0003] High risk of leakage: earthen pits or ordinary brick-lined ditches are easily corroded by acidic yellow water, causing the yellow water to seep into the base of the pit. The acidity of the pit mud is too high, which destroys the microbial environment of the pit mud and affects the fermentation stability.
[0004] Many impurities are mixed in: the open collection method makes it easy for mash and cellar mud to fall into the yellow water, clogging the pipes and reducing the purity of the yellow water. Subsequent use (such as esterification liquid preparation) requires additional filtration, resulting in low utilization rate of yellow water.
[0005] Inconvenient to operate: The collection port has no effective sealing structure, the yellow water is exposed to volatile flavor substances, and manual extraction is inefficient and poses safety hazards;
[0006] Short structural lifespan: Traditional materials (such as ordinary bricks and ceramic pipes) are prone to pulverization due to long-term acid corrosion, requiring frequent maintenance and increasing production costs.
[0007] Therefore, there is an urgent need for a collection and discharge structure that is leak-proof, easy to maintain, and can ensure the purity of yellow water. Utility Model Content

A yellow water ditch is formed between the ditch sidewall and the cellar sidewall. A cover plate is installed on the top of the yellow water ditch. The two ends of the cover plate overlap the top of the ditch sidewall and the cellar sidewall embankment. The lower part of the stainless steel yellow water tank is connected to the yellow water ditch.
[0014] Furthermore, the thickness of the yellow clay filling layer is 500 mm, and the thickness of the pit mud layer is 300 mm.
[0015] Furthermore, both the cellar sidewall and the ditch sidewall are made of solid bricks, the ditch sidewall is 120mm wide, and the height of the ditch sidewall is greater than the thickness of the yellow clay filling layer.
[0016] Furthermore, the width of the yellow water ditch is 200mm.
[0017] Furthermore, the cover plate is made of bluestone or solid wood, and the cover plate is 80mm thick and 350mm wide.
[0018] Furthermore, the stainless steel yellow water tank includes a tank body, a fixed cover, and a flip cover.

The cellar side wall 1 is built on the waterproof base plate 2, and a yellow clay filling layer 5 and a cellar mud layer 3 are arranged sequentially from bottom to top on the waterproof base plate 2; the stainless steel yellow water tank 4 is embedded in the cellar mud layer 3, and the top surface of the stainless steel yellow water tank 4 is flush with the top surface of the cellar mud layer 3; a ditch side wall 6 is provided on the inner side of one of the cellar side walls 1 near the stainless steel yellow water tank 4, forming a yellow water ditch between the ditch side wall 6 and the cellar side wall 1, and a cover plate 7 is provided on the top of the yellow water ditch. The two ends of the cover plate 7 overlap the top of the ditch side wall 6 and the cellar embankment of the cellar side wall 1, and the lower part of the stainless steel yellow water tank 4 is connected to the yellow water ditch.
[0031] In this embodiment, the yellow water produced during the fermentation of raw materials in the baijiu fermentation tank is collected by a stainless steel yellow water tank 4 installed inside the baijiu fermentation tank, and then flows out of the stainless steel yellow water tank 4 into the yellow water ditch. Since the baijiu fermentation tanks in the baijiu fermentation workshop are distributed in an array, each baijiu fermentation tank is equipped with a stainless steel yellow water tank 4, and the yellow water ditches of several baijiu fermentation tanks in the same row are interconnected, collecting the yellow water from several baijiu fermentation tanks in the same row.
[0032] Specifically, the thickness of the yellow clay filling layer 5 is 500 mm, and the thickness of the pit mud layer 3 is 300 mm. The side walls 1 of the pit and the side walls 6 of the ditch are both made of solid bricks. The width of the ditch side wall 6 is 120 mm, and the height of the ditch side wall 6 is greater than the thickness of the yellow clay filling layer 5.
[0033] Specifically, the width of the yellow water ditch is 200mm, and the cover plate 7 is made of bluestone slab or solid wood board, with a thickness of 80mm and a width of 350mm. The cover plate 7, the ditch sidewall 6, and the cellar sidewall 1 form a closed yellow water ditch.
[0034] Specifically, the stainless steel yellow water tank 4 includes a tank body 401, a fixed cover 402, and a flip cover 403. The fixed cover 402 is fixed to the top of the tank body 401, and the flip cover 403 is hinged to the fixed cover 402. The fixed cover 402 and the flip cover 403 form a cover that seals the tank body 401. Filter holes 404 are evenly distributed on the fixed cover 402 and the flip cover 403. A drain pipe 406 is provided at the bottom of the tank body 401, and the outlet of the drain pipe 406 is connected to a yellow water ditch. A handle 405 is provided on the flip cover 403. The stainless steel yellow water tank 4 serves as the core container for collecting yellow water in the fermentation pit. It has strong acid corrosion resistance and a long service life. The fixed cover 402 and the flip cover 403 with evenly distributed filter holes 404 on the top of the tank can intercept impurities in the fermented mash, improving the efficiency and quality of yellow water collection, and also facilitate opening the lid for inspection and maintenance.
[0035] Specifically, a layer of yellow clay cushion 8 is filled at the bottom of the yellow water ditch, and the yellow clay cushion 8 has a slope. With the sloped yellow clay cushion 8 at the bottom of the yellow water ditch, gravity guides the yellow water to flow directionally to the yellow water extraction point. Inside the fermentation workshop, since the yellow water ditches of several baijiu fermentation tanks in the same row are interconnected, only the last fermentation tank in that row needs to have a yellow water extraction point.
[0036] The above description is a preferred embodiment of the present utility model, used to explain the technical solution of the present utility model, and is not intended to limit the present utility model. Those skilled in the art can make conventional modifications, equivalent substitutions and improvements within the spirit and principles of the present utility model, all of which are still included within the protection scope of the present utility model.
