Description

Technical Field

[0001] This utility model relates to the field of brewing cellars, specifically a structure for an interconnected baijiu fermentation cellar group. Background Technology

[0002] Traditional baijiu fermentation pits typically employ an independent, closed structure, lacking effective interconnection between pits. This leads to difficulties in collecting the yellow water (a liquid byproduct produced during fermentation), resulting in resource waste and environmental pollution. Current technologies often treat the yellow water through manual extraction or simple diversion, which is inefficient and prone to contamination with impurities from the mash, affecting its quality. Furthermore, the mud in traditional pits lacks stability, resulting in uneven distribution of microbial communities, which negatively impacts baijiu fermentation and flavor compound formation.

[0003] Some improved fermentation pits have attempted to optimize yellow water collection by adding drainage ditches or water collection devices, but the following problems still exist: poor interconnectivity between pits, completely sealed partitions hinder the interaction of microorganisms and flavor substances between pits, which is detrimental to improving fermentation quality; the bonding strength between the pit mud and the wall is low, and it is prone to falling off after long-term use; yellow water collection is incomplete, and yellow water is prone to stagnation or leakage. Therefore, there is an urgent need for a fermentation pit structure that can efficiently collect yellow water while promoting the interaction of microorganisms between pits and improving fermentation stability. Utility Model Content

[0004] The present invention addresses the problems mentioned in the background art by providing an interconnected structure for a group of fermentation pits for baijiu (Chinese liquor).

[0005] To achieve the above objectives, the present invention adopts the following technical solution.

[0006] An interconnected baijiu fermentation cellar group structure includes a waterproof base slab, outer walls, partition walls, and enclosure walls. The outer walls, partition walls, and enclosure walls are all built on the waterproof base slab. The enclosure walls are set on the inner side of the outer walls. Multiple horizontal and vertical partition walls intersect each other to divide the rectangular fermentation area inside the enclosure walls into several fermentation tanks distributed in a grid-like array.

[0007] The inner wall of the fermentation tank is attached with a layer of side wall mud. The waterproof bottom plate inside the fermentation tank is successively set with a layer of yellow clay filling and a layer of bottom mud from bottom to top.

[0008] Both the partition walls and the surrounding walls adopt a perforated wall structure with a solid lower section and a perforated upper section. The perforated section is a wall with several evenly spaced cross-shaped perforations. The perforations are filled with clay and bamboo strips are inserted vertically. The inner ends of the bamboo strips on the surrounding walls extend into the clay layer on the side walls, while the two ends of the bamboo strips on the partition walls extend through the clay filling and into the clay layer on the side walls.

[0009] Furthermore, each fermentation tank has a yellow water collection tank embedded in the bottom mud layer, with the top surface of the yellow water collection tank flush with the top surface of the bottom mud layer. Each fermentation tank in the Nth column has interconnected yellow water ditches, and the yellow water collection tanks in the Nth and N+1th columns are connected to the yellow water ditches in the Nth column, where N is an odd number.

[0010] Furthermore, the yellow water collection tank includes a tank body, a fixed cover, and a flip cover. The fixed cover is fixed to the top of the tank body, and the flip cover is hinged to the fixed cover. The fixed cover and the flip cover form a cover to close the tank body. Filter holes are evenly opened on the fixed cover and the flip cover. A drain pipe is provided at the bottom of the tank body, and the tank body is connected to the yellow water ditch through the drain pipe. A handle is provided on the flip cover.

[0011] Furthermore, the two side walls of the yellow water ditch are a solid wall and a ditch wall, respectively. The ditch wall is built on a waterproof base plate and located inside the solid wall. The ditch wall is higher than the yellow clay filling layer. A cover plate is installed on the top of the yellow water ditch, with both ends of the cover plate overlapping the top of the ditch wall and the solid wall.

[0012] Furthermore, the bottom of the yellow water ditch is filled with a layer of yellow clay, which has a slope.

[0013] Furthermore, the trench wall is made of solid bricks, and the outer wall is made of concrete.

[0014] Furthermore, a layer of bluestone slabs is provided on the top of the outer wall, partition wall, and enclosure wall.

[0015] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0016] This invention utilizes a linked design of a yellow water collection tank and a continuous yellow water ditch to achieve centralized diversion of yellow water from multiple fermentation pits. Only an extraction point at the end is needed to recover yellow water from the entire row of pits, significantly reducing labor costs. The sloping yellow clay bedding layer and closed cover design at the bottom of the yellow water ditch ensure directional gravity flow of yellow water while preventing impurities from mixing in and evaporation losses. The partition walls and surrounding walls adopt a perforated wall structure, with pit mud filled in the perforations and bamboo strips inserted. This ensures structural stability and extends the bamboo strips to the side wall pit mud layers of adjacent pits, enhancing microbial communication between pits and promoting cross-pit migration of microbial communities and exchange of flavor substances. The grid-like fermentation tank layout combined with the perforated walls forms a three-dimensional interconnected fermentation micro-ecological system, improving the consistency of baijiu flavor. The embedded combination of the side wall pit mud layers with bamboo strips and perforated walls enhances the adhesion of the pit mud and prevents it from falling off. The openable lid design and filter hole structure of the yellow water collection tank facilitate cleaning impurities and maintenance, extending equipment life. The waterproof base plate, yellow clay filling layer, and pit mud layer at the bottom of the pit effectively prevent groundwater infiltration and maintain fermentation humidity. This utility model solves the problems of difficult collection of yellow water and inconsistent microbial activity in traditional pits through its interconnected structure, providing an efficient and stable fermentation environment for the production of high-quality baijiu.

The perforated section 202 is a wall with several cross-shaped perforations 2021 evenly spaced. The perforations 2021 are filled with pit mud and bamboo strips 2022 are inserted vertically. The inner end of the bamboo strips 2022 on the enclosure wall 3 extends into the pit mud layer 5 on the side wall. The two ends of the bamboo strips 2022 on the partition wall 2 pass through the pit mud filling and extend into the pit mud layer 5 on the side wall.

[0028] Specifically, each fermentation tank has a yellow water collection tank 4 embedded in the bottom mud layer 6. The top surface of the yellow water collection tank 4 is flush with the top surface of the bottom mud layer 6. Each fermentation tank in the Nth column has interconnected yellow water channels 10. The yellow water collection tanks 4 in the Nth and N+1th columns are all connected to the yellow water channels 10 in the Nth column, where N is an odd number. The yellow water collection 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 to close the tank body 401. Filter holes 40 are evenly opened on the fixed cover 402 and the flip cover 403. 4. A drain pipe 406 is provided at the lower part of the tank body 401. The tank body 401 is connected to the yellow water ditch 10 through the drain pipe 406. A handle 405 is provided on the flip cover 403. The two side walls of the yellow water ditch 10 are a solid wall 201 and a ditch wall 8, respectively. The ditch wall 8 is built on the waterproof base plate 13 and is located inside the solid wall 201. The ditch wall 8 is higher than the yellow clay filling layer 7. A cover plate 9 is provided on the top of the yellow water ditch 10. The two ends of the cover plate 9 overlap the top of the ditch wall 8 and the solid wall 201. A layer of yellow clay cushion 11 is filled at the bottom of the yellow water ditch 10. The yellow clay cushion 11 has a slope. A bluestone slab layer 12 is provided on the top of the outer wall 1, partition wall 2, and enclosure wall 3.

[0029] In this embodiment, the ditch wall 8 is a solid brick wall with a width of 120mm; the outer wall 1 is a concrete wall with a width of 250mm; the partition wall 2 and the enclosure wall 3 are constructed of solid bricks with a width of 240mm; the bluestone slab layer 12 is 30mm thick. The yellow clay filling layer 7 is 500mm thick, the bottom mud layer 6 is 300mm thick, and the side wall mud layer 5 is 130mm wide. The yellow water ditch 10 is 200mm wide, and the cover plate 9 is made of bluestone slabs or solid wood planks, with a thickness of 80mm and a width of 350mm. The cover plate 9, the ditch wall 8, and the solid wall 201 form a closed yellow water ditch 10. The yellow water collection tank 4 is made of stainless steel and is 300mm high. The spacing between the individual cross-shaped grommets 2021 is 120mm + 240mm + 120mm.

[0030] The yellow water collection tank 4 is the core container for collecting yellow water in the fermentation tank. The cover formed by the fixed cover 402 and the flip cover 403, through the filter holes 404, can intercept impurities in the mash, improving the efficiency and quality of yellow water collection, and also facilitating access for maintenance by opening the flip cover 403 via the handle 405. A sloping yellow clay bedding layer 11 is installed at the bottom of the yellow water ditch 10, using gravity to guide the yellow water to flow directionally to the yellow water extraction point. Since the yellow water ditches 10 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.
