Description

Technical Field

[0001] The invention relates to the field of wine-making cellars, and in particular to a Luzhou-flavor liquor fermentation tank and a construction method thereof. Background Art

[0002] In the production of Luzhou-flavor baijiu (Luo-aroma liquor), traditional cellars suffer from poor geological adaptability in riverbed areas, inefficient yellow water collection, and insufficient cellar mud stability. The high groundwater level and soft soil in riverbed areas make cellars prone to settlement and cracking, with annual settlement exceeding 10 mm. This results in leakage rates as high as 20%-30% in traditional cellars. The acidic yellow water, with a pH of 3.5-4.5, is prone to corroding ordinary brickwork and creating an imbalance in the cellar mud microbiome, increasing the risk of off-flavors (earthy, musty, and pungent) in the resulting liquor. Traditional cellars use open pits or pipes to collect yellow water, resulting in an influx of more than 40% impurities into the mash, less than 50% yellow water utilization, and labor-intensive manual extraction, leading to volatilization losses of more than 15% in flavor compounds. Traditional cellar walls lack anchoring structures, leading to an average annual cellar mud shedding rate of 25%, a 30% reduction in the colonization rate of functional microorganisms (such as caproic acid bacteria), and isolation between cellars hinders microbial interaction, resulting in poor fermentation consistency (base liquor ester content deviation ≥15%).

8. The Luzhou-flavor liquor fermentation tank according to claim 1, characterized in that: The pressure top layer comprises a reinforced concrete pressure top layer, a stone bonding layer and a bluestone slab arranged from bottom to top.

9. A method for constructing a Luzhou-flavor liquor fermentation tank according to any one of claims 1 to 8, comprising the following steps: (1) Foundation pretreatment S1. Site selection and foundation pit excavation: Select a river channel area, excavate the foundation pit to a stable bearing layer with a depth of not less than 1.5m, and level the pit bottom; S2. Gravel backfill: Lay a 300mm graded gravel layer, compact it with vibration, and the permeability coefficient should not be higher than 1×10 -5 cm / s, S3. Loess tamping: Backfill the loess in layers, with each layer no thicker than 300mm. Sprinkle water until the moisture content reaches 18%, and roll until the compaction coefficient is no less than 0.

94. (2) Waterproof baseboard construction S1. Pouring of cushion layer: pouring 100mm thick C15 concrete cushion layer, with surface flatness deviation not exceeding 3mm; S2. Waterproof base: lay a 20mm thick 1:3 cement mortar leveling layer and maintain for 3 days; S4. Roll material laying: fully lay two layers of 1.5mm thick synthetic polymer waterproofing roll material, with an overlap width of not less than 100mm, and hot-melt weld the seams; S5, Fine stone concrete protection: pour 50mm thick C20 fine stone concrete layer, cover with waterproof membrane; S6. Construction of anti-seepage layer: tie double-layer Ø10@120 steel mesh, weld 3mm thick galvanized water-stop steel plate in the middle, pour 300mm thick C30 P6 anti-seepage concrete, vibrate and compact it, cover with film and maintain for 7 days; (3) Wall construction S1. Exterior wall construction: Support the formwork, tie a double layer of Ø12@120 steel mesh, embed a 3mm galvanized waterstop steel plate, pour 300mm thick C30 P6 anti-seepage concrete, and form the joint with the waterproof base plate anti-seepage layer into one piece; use 120mm thick MU15 shale solid bricks and M10 cement mortar to build the solid wall, with a vertical deviation of no more than 3mm; S2. Construction of eyelet wall: Build nine layers of 370mm thick solid bricks and five layers of 240mm thick solid bricks to form the first and second solid wall parts, then build the eyelet part. After every nine layers of 240mm thick eyelet bricks, add a layer of solid brick strip. The spacing of the cross eyelets from top to bottom is 120mm, 240mm, and 120mm. Fill the cross eyelets with pit mud and vertically insert Φ8 bamboo strips, leaving 30mm exposed. Top layer and sealing: Pour 50mm thick C25 reinforced concrete on the top of the wall with 3Φ10@150 reinforcement and scrape the surface flat; apply 40mm thick cement-based adhesive, lay 30mm thick bluestone slabs, and fill the slab seams with acid-resistant sealant; (4) Laying and maintenance of pit mud layer S1. Integrated construction of side walls and bottom: Build a 120mm thick solid brick ditch wall in the cellar, lay a 1% slope yellow clay cushion layer on the bottom of the ditch, add a cover plate on the top, fill the fermentation area in the cellar with a 500mm thick layer of yellow clay to form a yellow clay filling layer, then lay a 130mm thick side wall mud layer and a 300mm thick bottom mud layer in layers, and knead and compact the mud at the joints; S2. Moisturizing: Cover with sacks and spray with water for 30 days, maintaining humidity at 80%-85%; (5) Installation of yellow water collection system A foundation pit is excavated at the positioning point of the pit mud layer at the bottom of the pool, and the stainless steel tank body is buried, keeping its top surface flush with the pit mud layer at the bottom of the pool, and the drainage pipe is facing the yellow water ditch.
