DETAILED DESCRIPTION

[0031] The present invention will be further described below with reference to the accompanying drawings.

[0032] like Figure 1-Figure 5As shown, the embodiment of the present application proposes a cellar structure for brewing liquor, including a cellar, the cellar including a cellar bottom 2 and a side wall 1, the cellar bottom 2 is provided with a base structure, a concave yellow water collection pit 12 is provided at the center of the upper surface of the base structure, and a water collection ditch 10 is also provided on the upper surface of the base structure, the water collection ditch 10 extends from the peripheral side of the upper surface of the base structure to connect to the yellow water collection pit 12, the bottom of the yellow water collection pit 12 is lower than the bottom of the water collection ditch 10, and the water collection ditch 10 is inclined downward toward the yellow water collection pit 12; the water collection ditch 10 and the yellow water collection pit 12 are both provided with cellar walls 9, the cellar walls 9 are higher than the upper surface of the base structure, and the cellar walls 9 are provided with a plurality of channels. There is an infiltration gap; the above-mentioned cellar wall 9 divides the upper surface of the above-mentioned base structure into a cellar mud part and a water collection part which are separated from each other. The above-mentioned water collection part includes the above-mentioned water collection ditch 10 and the above-mentioned yellow water collection pit 12 which are interconnected. The upper surface of the above-mentioned base structure is inclined downward from the above-mentioned cellar mud part toward the above-mentioned water collection part; the above-mentioned cellar mud part is filled with a cellar mud layer 8 and the above-mentioned cellar mud layer 8 is flush with the upper end of the above-mentioned cellar wall 9. The above-mentioned infiltration gap is used to allow the yellow water in the above-mentioned cellar mud layer 8 to infiltrate into the above-mentioned water collection part; the upper opening of the above-mentioned water collection part is covered with a filter plate; it also includes a yellow water pipe 7, one end of the above-mentioned yellow water pipe 7 extends into the above-mentioned yellow water collection pit 12, and the other end extends to the position of the above-mentioned side wall 1. The yellow water pipe 7 can collect the yellow water in the yellow water collection pit 12 to the outside.

[0033] First of all, it should be stated that the cellar wall 9 separates the cellar mud layer 8 from the water collection ditch 10 and the yellow water collection pit 12, and at the same time, the infiltration gap is set to allow the yellow water to flow from the cellar mud layer 8 into the water collection ditch 10 and the yellow water collection pit 12, which can retain the traditional craftsmanship of the traditional stone cellar mud bottom and improve the flavor and quality of the liquor; and the upper surfaces of the water collection ditch 10 and the base structure are set with a slope, which can make the yellow water more efficiently flow into the yellow water collection pit 12, and use gravity to accelerate the yellow water to converge to the central yellow water collection pit 12, reduce yellow water retention and residue deposition, and improve the drip cellar efficiency; by setting a filter plate, the lees are prevented from falling into the water collection ditch 10 and the yellow water collection pit 12; and the setting of the yellow water pipe 7 further improves the drip cellar efficiency.

[0034] The pool bottom 2 is formed by manually compacting plain soil, and the sidewall 1 is built with bluestone strips to form a stone cellar. The base structure includes a concrete leveling layer 3, a waterproof layer 4, a fine stone concrete protective layer 5, and a concrete base plate 6, which are laid sequentially from bottom to top. The concrete leveling layer 3 is specifically a 100mm thick C15 concrete leveling layer 3, the waterproof layer 4 is a 1.5mm thick polyethylene polyester polymer waterproof membrane, the fine stone concrete protective layer 5 is a 50mm thick C25 fine stone concrete protective layer, and the concrete base plate 6 is a large C30P8 steel fiber concrete slab. Polypropylene fiber concrete slabs can also be used to ensure sufficient crack resistance. The base structure forms the stone cellar floor as a whole, which has high stability and waterproof performance. At the same time, the concrete base plate 6 can also be replaced with a base plate built with strips of stone, and the joints are filled with environmentally friendly materials for sealing.

[0035] To further improve the efficiency of dripping, the aforementioned drainage ditches 10 are arranged in multiple intervals along the circumference of the yellow water collection pit 12. These can be cross-shaped, star-shaped, or well-shaped. Multiple drainage ditches 10 can increase the efficiency of yellow water collection, and an anti-clogging filter is required at the intersection of the multiple drainage ditches 10 and the yellow water collection pit 12. Furthermore, a food-grade stainless steel pipe can be buried at the bottom of the drainage ditches 10. The pipe is provided with holes to facilitate the flow of yellow water through the suction of an external pump. Furthermore, the inner wall of the groove is coated with a hydrophobic material to reduce the flow resistance of the yellow water.

[0036] In this embodiment, the extension portion of the pit mud portion toward the water collection portion has a downward slope, and the slope direction is set according to the actual situation. In this embodiment, the slope between the pit mud portion and the above-mentioned water collection portion is 4%, and the slope range can also be set according to actual conditions. That is to say, by setting the inclined slope, the yellow water flows along the slope toward the water collection ditch 10 and the yellow water collection pit 12 under the action of gravity, thereby improving the yellow water collection efficiency.

[0037] The above-mentioned cellar wall 9 is made of multiple solid bricks. The above-mentioned seepage gap includes the gap left at the mortar joint between two adjacent solid bricks. Solid bricks can be used in this embodiment and are built with cement mortar. The mortar joints must not be full to form a seepage gap so that the yellow water can naturally penetrate the yellow mud. In addition, a single brick is laid on the top of the drainage ditch and the yellow water collection pit 12 to form a slot to clamp the stainless steel cover.

[0038] The above-mentioned filter plate includes a filter screen layer 13 and a cover plate layer 11 connected in sequence from bottom to top. The above-mentioned cover plate layer 11 is provided with through holes. That is to say, in this embodiment, a layer of 20-mesh stainless steel filter screen is first laid on the drainage ditch and the yellow water collection pit 12, and then a 2mm thick, 250×700 stainless steel cover plate is laid, and through holes are drilled on the cover plate. The combination of the filter screen layer 13 and the cover plate layer 11 can block the wine ditch outside the yellow water collection pit 12 and ensure the smooth flow of yellow water in the drainage ditch 10 and the yellow water collection pit 12.

[0039] This embodiment also proposes a method for constructing a cellar structure for liquor brewing, comprising the following steps:

[0040] S1: compacting the yellow mud layer of the pool bottom 2; the yellow mud layer is generally plain soil, and the compaction method generally adopts manual compaction or mechanical compaction.

[0041] S2: The side wall 1 is built with stone blocks; the side wall 1 is built with multiple bluestone blocks and cement mortar, with two blocks in each layer and one block in each layer. When laying the blocks, first retreat and then advance, and fill the mortar joints. Use waterproof cement mortar to point the joints.

[0042] In this embodiment, the stone blocks are 300mm wide and 300mm high, with each layer consisting of two straight and one diagonal blocks. During masonry, the blocks are laid with a back-and-forth approach, leaving space for the concrete base slab 6. The mortar joints must be full, using a 1:2 waterproof cement mortar. The back-and-forth approach means that when laying the wall, the wall at the structural column will extend a certain distance at regular intervals and then retract, alternating until the top of the wall is reached. This "back-and-forth" approach increases the contact area between the structural column and the wall, thereby improving the stability of the overall structure.

[0043] S3: The above-mentioned base structure is laid on the upper end of the above-mentioned pool bottom 2, and the above-mentioned yellow water collection pit 12 is concavely set in the center of the above-mentioned base structure. Specifically, a concrete leveling layer 3 is poured on the rammed earth at the upper end of the above-mentioned pool bottom 2, and a waterproof layer 4 is laid on the above-mentioned concrete leveling layer 3. The edge of the above-mentioned waterproof layer 4 is turned up and extended to the preset position of the above-mentioned side wall 1. A fine stone concrete protective layer 5 of a preset thickness is poured on the upper end of the waterproof layer 4, and waterproof cement mortar is applied to the connection between the above-mentioned pool bottom 2 and the side wall 1. It is smoothed and compacted, and then a concrete bottom plate 6 is poured. The upper surface of the concrete bottom plate 6 is provided with a slope, which is a slope that is tilted downward toward the center on all sides to ensure that the yellow water can stably flow toward the collection ditch 10 and the yellow water collection pit 12 under the action of gravity.

[0044] S4: Lay the above-mentioned yellow water pipe 7, the lower end of the yellow water pipe 7 extends into the yellow water collection pit 12, and the upper end of the yellow water pipe 7 extends out of the cellar; specifically, the yellow water pipe is laid along the cellar wall and bottom plate in a corner of the cellar and extends into the yellow water collection pit 12, and a ground chuck interface is made at the ground. The chucks of multiple adjacent cellars are concentrated in the same corner to form a yellow water collection pipeline network, thereby achieving high efficiency in yellow water collection.

[0045] S5: The cellar wall 9 is installed on the upper surface of the base structure, and the filter plate is installed to cover the upper opening of the water collection portion formed by the cellar wall 9. The cellar wall 9 is built using solid bricks and cement mortar. The mortar joints are not full to form the above-mentioned seepage gap, and the top layer of the cellar wall 9 is reserved with a slot for limiting the position of the filter plate. In this embodiment, a brick-built cross ditch is preferably built in the middle of the cellar for collecting yellow water. M10 solid bricks and M7.5 cement mortar are used for masonry. The mortar joints must not be full to form a seepage gap, allowing yellow water to naturally penetrate the yellow mud. A single brick is laid on the top of the drainage ditch and yellow water collection pit 12 to form a slot to hold the cover layer 11 and ensure the stability of the cover layer 11 after installation.

[0046] S6: Fill the above-mentioned cellar mud part with two layers of cellar mud 8 of preset thickness, compact the lower cellar mud layer 8 mechanically, and compact the upper cellar mud layer 8 manually to ensure the density of the cellar mud and improve the quality of the liquor.

[0047] The filter plate, cover layer 11, yellow water pipe 7, etc. mentioned in this embodiment are all made of food-grade materials to ensure the quality of liquor fermentation.

[0048] In summary, the embodiment of the present application proposes a cellar structure and construction method for liquor brewing, which retains the stone cellar mud bottom fermentation process, inherits the requirements of ancient brewing methods, and improves the quality of liquor; the cross ditch at the cellar bottom adopts a structure with four sides sloping toward the central water collection well, and uses gravity to accelerate the yellow water to converge to the central yellow water collection pit 12, reducing yellow water retention and residue deposition, and improving the efficiency of dripping. In addition, the construction process of "first building the side wall 1 and then pouring the concrete bottom plate" is adopted, so that the concrete is fully embedded in the stone gap to form an anchoring effect, which greatly improves the integrity of the cellar and effectively suppresses the risk of shrinkage and deformation. The overall solution takes into account the stone cellar mud bottom fermentation, efficient dripping and enhanced cellar structure stability, providing an innovative solution for cellar process optimization.
