Description

Technical Field

[0001] This utility model relates to the field of liquor brewing technology, specifically to a prefabricated cellar embankment module and a cellar. Background Technology

[0002] Baijiu is a traditional Chinese distilled spirit, and its unique flavor largely depends on the fermentation vessel—the cellar.

[0003] Traditional cellars, especially the cellar walls, are constructed on-site by manually ramming high-quality yellow mud in layers. However, this manual construction method presents several problems: the quality of the construction is difficult to quantify and control uniformly; the construction period is long; and the erection and dismantling of temporary formwork during construction results in material losses and resource waste. Utility Model Content

[0004] In view of this, the present invention provides a prefabricated cellar embankment module and cellar to solve the problems of long construction cycle, difficulty in quality control and waste of material resources in cellar construction.

[0005] Firstly, this utility model provides a prefabricated cellar embankment module, including a main body, which is prefabricated using a mold. The beneficial effects are: it significantly shortens the cellar construction cycle (from several months to several days), and by prefabricating in a factory mold, quality can be uniformly controlled, and waste of material resources can be reduced.

[0006] In one optional embodiment, at least one surface of the main body facing the interior of the fermentation pit is a microbial attachment surface. The beneficial effects are: the microbial community can decompose raw materials such as starch and sugars, promoting saccharification and alcoholic fermentation; the organic acids produced by microbial metabolism can also regulate the pH of the fermentation environment, stabilize temperature and humidity, and ensure continuous brewing; the synergistic effect of the attached microbial community and the minerals in the pit mud can enhance the taste of the baijiu; the microorganisms in the fermentation pit form a stable symbiotic system, mutually restricting and synergistically interacting. For example, lactic acid bacteria produce lactic acid, which can inhibit the reproduction of harmful bacteria, while dominant bacteria such as caproic acid bacteria maintain ecological balance through their metabolic products, ensuring brewing safety and quality consistency.

[0007] In one alternative implementation, the microbial attachment surface is a rough surface or a textured surface. The advantage is that it allows for the attachment of a larger microbial community.

[0008] In one optional embodiment, the main body is provided with at least one reserved channel for pre-installing ventilation and / or temperature measurement and / or irrigation pipelines and / or injecting bacterial solution; the interior of the main body has multiple micropores, one end of which communicates with the reserved channel, and the other end of which extends to the surface of the main body facing the inside of the fermentation pit. The beneficial effects are: increased microbial activity through ventilation and temperature control; injection of bacterial solution to artificially supplement microorganisms when their numbers are insufficient, ensuring sufficient microbial population, thereby enhancing the flavor of the baijiu and making it smoother and fuller; precise point-to-point installation according to the preset channels during module installation; and improved intelligence and controllability of the fermentation pit.

[0009] In one alternative embodiment, the interior of the body has a plurality of micropores, one end of which communicates with a pre-reserved channel, and the other end of which extends to the surface of the body facing the interior of the cellar.

[0010] In one alternative implementation, a connecting structure is provided at the bottom of the main body. The beneficial effect is that it increases the overall stability and integrity of the pit.

[0011] Secondly, this utility model also provides a cellar, including a foundation pit with an opening at the top; layers arranged along the inner and bottom walls of the foundation pit; and prefabricated cellar embankment modules disposed inside the foundation pit and connected to the layers, wherein two adjacent prefabricated cellar embankment modules divide the inner cavity of the foundation pit into a liquid storage chamber. Since a cellar including a cellar embankment prefabricated module has the same effect as a single prefabricated cellar embankment module, it will not be described in detail here.

[0012] In one alternative embodiment, the layer group includes: a subgrade layer; a subbase layer above the subgrade layer; a waterproof layer above the subbase layer; a cement mortar protective layer above the waterproof layer; and a waterproof roof slab above the cement mortar protective layer.

[0013] In one alternative embodiment, the prefabricated cellar embankment module is connected to the waterproof roof slab; and / or, a clay layer is provided at the junction of the prefabricated cellar embankment module and the waterproof roof slab; and / or, kiln mud is provided on the surface of the prefabricated cellar embankment module facing the inside of the cellar; and / or, a bluestone slab is provided on the top of the prefabricated cellar embankment module.

[0014] Thirdly, this utility model also provides a construction method for a cellar, comprising the following steps:

[0015] S1. Prefabricated cellar modules are produced in a standardized factory.

[0016] S2. Arrange the layers along the inner sidewall and bottom wall of the foundation pit;

[0017] S3. Lay out the layout of the foundation pit and divide it into multiple module positioning areas along the horizontal direction of the foundation pit;

[0018] S4. Within each module positioning area, multiple prefabricated cellar modules are assembled together and positioned within that module positioning area.

[0019] The beneficial effects are: modular production and installation significantly shorten the construction time of the kiln pits and improve construction efficiency; if a section of the kiln embankment is damaged, it can be replaced with a module of the same specifications, making maintenance convenient.

[0020] In one alternative implementation, in step S4, the two prefabricated modules of the kiln embankment are bonded together with an adhesive; and / or after step S4, the gaps are filled and smoothed with an adhesive; after the gaps are filled and smoothed, a layer of active kiln mud is applied to the surface of the kiln embankment facing the inside of the kiln.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Baijiu is a traditional Chinese distilled spirit, and its unique flavor largely depends on the fermentation vessel—the fermentation pit. Traditionally, the fermentation pits, especially the pit walls, were constructed on-site using high-quality yellow mud, layered and rammed by hand. However, this construction method has several drawbacks:

[0029] Highly dependent on manual labor and experience: The ramming process requires experienced master craftsmen to operate, which is extremely labor-intensive, inefficient, and difficult to quantify and control the quality.

[0030] The construction period is long: from selecting mud, treading mud, ramming and compacting to air-drying and curing, the whole process is time-consuming, which seriously restricts the construction speed of new pits.

[0031] Poor quality consistency: Because it is made by hand on site, the density and uniformity of different fermentation pits or even different parts of the same fermentation pit may vary, resulting in an unstable fermentation environment and affecting the uniformity of the quality of the liquor.

[0032] Resource waste: The need to set up and dismantle temporary formwork results in material loss throughout the process.

[0033] Therefore, there is an urgent need in this field for a new technology that can achieve standardized, industrialized production and ensure the core functions of the fermentation pit to overcome the above-mentioned problems.

[0034] The following is combined with Figures 1 to 3 The following describes embodiments of the present invention.

[0035] According to an embodiment of the present invention, referring to Figure 1 , Figure 2 Firstly, a prefabricated cellar embankment module is provided, including a main body 1. The main body 1 is formed by high-pressure pressing or casting of a special yellow mud material fermented with baijiu through a mold. Its cross-section is rectangular or trapezoidal, and its length can be set according to the standard cellar size.

[0036] In this embodiment, standardized production of cellar embankments is achieved by prefabricating the prefabricated modules using molds. This transforms traditional craftsmanship into industrialized production, ensuring consistent module size, density, and composition, and controllable quality, thus eliminating absolute reliance on the experience of individual craftsmen. It significantly reduces on-site construction time (from months to days), saving substantial labor and time costs, resulting in significant economic benefits.

[0037] At least one surface of the body 1 facing the interior of the pit 12 is a microbial attachment surface 2.

[0038] The microbial attachment surface 2 is a rough or textured surface. This design increases the surface area, facilitating the application and adhesion of kiln mud 4, and providing more habitats for microorganisms.

[0039] The main body 1 is provided with at least one reserved channel 3, which is used for pre-installing ventilation and / or temperature measurement and / or drip irrigation pipelines and / or injecting bacterial solution. In the process of baijiu brewing, microorganisms play a key role. When the number of microorganisms is insufficient, bacterial solution can be injected through the reserved channel 3. At the same time, the reserved channel 3 is used for ventilation and temperature measurement to provide a suitable environment for the injected bacterial solution to promote cultivation. Ultimately, this achieves microbial inoculation inside the prefabricated cellar module, which helps to optimize the microbial environment during the brewing process.

[0040] The reserved duct 3 can be arranged during the standardized prefabrication of the main body 1 in the factory, reducing on-site pouring, drilling and other processes, and shortening the construction cycle of the pit.

[0041] The number of reserved channels 3 can be one or more, and can be arranged according to the actual situation. Reserved channels 3 can be set as vertical channels or as inclined channels. When set as vertical channels, it is convenient to directly inject bacterial solution, ventilate, and measure temperature from the top of the pit, making construction simpler, and the installation and debugging of some equipment is also relatively easy during subsequent use. When set as inclined channels, it is possible to more accurately guide the flow of bacterial solution to specific areas according to the specific structure of the pit and the distribution requirements of microorganisms. At the same time, the inclined channels can reduce the possibility of blockage by debris to a certain extent.

[0042] The interior of the main body 1 has multiple micropores. One end of each micropore connects to a pre-reserved channel 3, and the other end extends to the surface of the main body 1 facing the interior of the pit 12. These micropores serve as crucial channels connecting the pre-reserved channel 3 to the surface of the main body 1 facing the interior of the pit. Microbial communities cultivated using the pre-reserved channel 3 pass through these micropores and attach to the surface of the main body 1 facing the interior of the pit 12. The micropores prevent the bacterial solution from being directly exposed to the pit environment, enabling the directional migration of the microbial community and reducing interference from the external environment on the initial microbial community.

[0043] A connecting structure is provided at the bottom of the main body 1. This connecting structure is a pre-reserved channel 3, which is used for quick, accurate positioning and firm connection between multiple modules. The connecting structure is a structure with the same material as the bottom of the kiln embankment on the concrete waterproof top plate. The structure has a protrusion with the same diameter as the pre-reserved channel 3 and a height of 3-5cm. The protrusion is adapted to the pre-reserved channel 3.

[0044] According to an embodiment of the present invention, in a second aspect, a cellar is also provided, referring to... Figure 3 It includes a foundation pit, layers, and prefabricated pit embankment modules. The top of the foundation pit is open; the layers are arranged along the inner and bottom walls of the foundation pit; the prefabricated pit embankment modules are set inside the foundation pit and connected to the layers, and two adjacent prefabricated pit embankment modules divide the inner cavity of the foundation pit into liquid storage chambers.

[0045] The layer group includes a plain soil layer 11, a subbase layer 10, a waterproof layer 9, a cement mortar protective layer 8, and a waterproof roof slab 7. The subbase layer 10 is located above the plain soil layer 11; the waterproof layer 9 is located above the subbase layer 10; the cement mortar protective layer 8 is located above the waterproof layer 9; and the waterproof roof slab 7 is located above the cement mortar protective layer 8.

[0046] The prefabricated cellar embankment module is connected to the waterproof roof slab 7.

[0047] A clay layer 6 is provided at the junction of the prefabricated cellar embankment module and the waterproof roof slab 7. The clay layer 6 can fit tightly against the waterproof roof slab 7 and the prefabricated cellar embankment module, playing a good role in connection and sealing.

[0048] The surface of the prefabricated cellar embankment module facing the inside of the cellar 12 is covered with kiln mud 4.

[0049] The top of the prefabricated cellar embankment module is fitted with bluestone slabs 5, which serve to reinforce and enhance the appearance.

[0050] According to an embodiment of the present invention, a third aspect also provides a method for constructing a cellar, comprising the following steps:

[0051] S1. Standardized production of prefabricated cellar embankment modules in a factory; within the factory, nutrient-rich and microbial-infused yellow mud material prepared according to a traditional formula is injected into specially designed molds and shaped through processes such as high-pressure pressing, vibration compaction, or vacuum extrusion. Then, after specific curing methods, standardized cellar embankment modules are formed. Specifically, this includes the following steps:

[0052] Module Design: Design a three-dimensional trapezoidal module with side height × bottom length × bottom width × top width of a mm × b mm × c mm × d mm. The module has at least one pre-set longitudinal circular hole with a diameter of r mm inside. The outer surface of the module is embossed using a mold to create a uniform textured surface.

[0053] Material preparation: Prepare yellow clay and other nutrients, mix them thoroughly, and set aside as mud.

[0054] Molding and Curing: The mixed clay is filled into a steel mold and pressed into shape under sufficient pressure. After the molding meets the demolding conditions, the module is demolded and subjected to standard curing.

[0055] S2. Arrange the layers along the inner sidewall and bottom wall of the foundation pit. In the foundation pit, arrange the plain soil layer 11, the cushion layer 10, the waterproof layer 9, the cement mortar protective layer 8, and the waterproof top slab 7 in sequence.

[0056] S3. Lay out the layout of the foundation pit and divide it into multiple module positioning areas along the horizontal direction of the foundation pit;

[0057] S4. Within each module's positioning area, multiple prefabricated kiln embankment modules are assembled and positioned within that area. Two assembled kiln embankment modules are bonded together using a special biocompatible adhesive to form the completed kiln embankment wall, ensuring a tight fit between the modules and the kiln bottom, and between the modules themselves. The biocompatible adhesive is a yellow clay adhesive, with a composition similar to the module's clay material.

[0058] S5. Fill and smooth the gaps with a special biocompatible adhesive; after filling and smoothing the gaps, apply a layer of active kiln mud to the surface of the kiln embankment facing the inside of the kiln 12, and carry out the standard "kiln maintenance" process to activate the microbial community and spread it to the entire kiln embankment.

[0059] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
