Abstract
Description
Technical Field
[0001] The invention relates to the technical field of wine cellar maintenance, and in particular to a wine cellar sealing treatment method. Background Art
[0002] Sealing mud (cellar skin mud) plays a vital role in liquor brewing, especially in the cellar sealing stage. Its main function is to seal the cellar to prevent outside air from entering, thereby providing a stable environment for the fermentation process. At the same time, the sealing mud provides rich nutrients for the microbial community in the cellar, promotes the growth and fermentation of microorganisms, and ultimately improves the flavor and quality of the liquor. The beneficial ingredients in the sealing mud, such as acids, alcohols, esters, amino acids, etc., can effectively support the activities of microorganisms, promote fermentation and produce the aroma substances required for the wine. This process not only ensures the unique flavor of the wine, but also avoids the problems of burning and leakage through its good water retention and viscosity, further optimizing the winemaking environment.
[0003] Although the role of sealing mud cannot be underestimated, in actual application, the use of sealing mud also faces some technical difficulties, especially the problem of bacterial plaque in a humid environment. In traditional liquor brewing, sealing mud often produces mildew on the surface, especially in the rainy season, when the increased humidity provides a breeding ground for the growth of mold. Aerobic microorganisms such as mold will spread rapidly on the surface of sealing mud, causing an imbalance in the microbial community, thus affecting the fermentation process and the final wine quality. The occurrence of this mildew not only destroys the microbial ecological environment of the sealing mud, but may also produce unpleasant odors, and in severe cases even affect the taste and aroma of the liquor.
[0004] In order to solve the problem of bacterial plaque, many liquor companies have adopted strict cellar sealing management measures, including controlling the temperature and humidity of the cellar, increasing ventilation, and regularly checking the sealing of the cellar. However, these measures can only slow down the formation of bacterial plaque, and cannot fundamentally prevent the growth of mold on the surface of the cellar sealing mud. Although some companies carry out cleaning and maintenance after sealing the cellar, these measures cannot completely eliminate the impact of bacterial plaque, especially in seasons with heavy humidity or when management is not in place, the problem of bacterial plaque is still serious. This phenomenon not only affects the quality and output of the wine, but may also increase the production costs of the company.
[0005] Another problem faced by the prior art is the treatment method for moldy cellar mud. Usually, moldy cellar mud needs to be replaced or sterilized to prevent the further spread of mold and negative impact on wine quality. However, existing treatment methods such as directly replacing the cellar mud or using chemical fungicides can usually only temporarily solve the problem and may have a greater impact on the microbial community. The existing technology also fails to provide an effective means to prevent the formation of bacterial plaque without affecting the balance of the microbial community.
[0006] In addition, some alternative methods to cellar sealing mud, such as stainless steel covers or cellar cloth sealing, also have certain limitations. Although stainless steel covers can provide a good sealing effect, there may be problems with material quality and welding during use, and even food safety risks. Especially during long-term use, the corrosion of metal materials may affect the quality of the wine. Although cellar cloth sealing can isolate the air and create a good fermentation environment, its sealing and durability are easily damaged, and it requires regular maintenance and replacement, which increases maintenance costs. Overall, the existing alternatives have not been able to fundamentally solve the problem of plaque formation on the surface of the cellar sealing mud, nor have they been able to reduce costs or improve effects while improving efficiency.
[0007] Therefore, although the industry has taken a variety of measures to reduce the formation of bacterial plaque on the surface of the cellar mud, these measures still have many shortcomings, especially in terms of long-term effectiveness, cost control and protection of wine quality, there is still much room for improvement.
[0008] In view of this, the present invention is proposed. Summary of the invention

[0020] In an optional embodiment, the viscous soil is yellow, purple or red viscous soil without impurities and pollution.
[0021] In an optional embodiment, the method for preparing the concentrated yellow mud aqueous solution comprises:
[0022] Take yellow clay, dry it, and then crush it to obtain clay particles;
[0023] The concentrated yellow mud aqueous solution is prepared by utilizing the clay particles.
[0024] In an optional embodiment, the concentrated yellow mud aqueous solution is prepared by using the clay particles, comprising:
[0025] The second hot water is added to the clay particles, and the mixture is sealed and soaked for no less than 24 hours to obtain the concentrated yellow mud aqueous solution in a slurry state.
[0026] In an optional embodiment, the second hot water, in winter, is water with a temperature not lower than 90°C;
[0027] In seasons other than winter, water with a temperature not lower than 85°C is used.
[0028] In an optional embodiment, the mass ratio of the clay particles to the second hot water is (1.3-3):1.
[0029] In an optional embodiment, the step of adding a second hot water to the clay particles, sealing and soaking for no less than 24 hours to obtain the slurry-like concentrated yellow mud aqueous solution further comprises:
[0030] Adding the microbial inhibitory component in a weight fraction of 0.1 to 5 into the concentrated yellow mud aqueous solution;
[0031] and / or, the weight fraction of the microorganism inhibitory component contained in the microorganism inhibitory solution is 0.1 to 5;
[0032] In an alternative embodiment, the microbial inhibitory component comprises potassium metabisulfite.
[0033] In an optional embodiment, the concentration of the microbial inhibitory component in the concentrated yellow mud aqueous solution, and the concentration of the microbial inhibitory component in the microbial inhibitory solution, are positively correlated with the temperature of the weather and the organic matter content in the cellar sealing mud.

[0041] Compared with the prior art, the present invention has the following beneficial effects:
[0042] (1) By preparing a concentrated yellow mud water solution and adding microbial inhibitory components, or spraying a microbial inhibitory solution containing microbial inhibitory components alone, the growth of bacteria or mildew on the surface of the cellar mud can be effectively avoided. The cellar-drag treatment method of concentrated yellow mud water creates an environment that inhibits the growth of bacteria by isolating the organic matter inside the cellar mud from contact with the air. This not only keeps the high-quality components of the cellar mud intact, but also significantly reduces the impact of microorganisms such as mold on the surface of the cellar mud, avoiding the formation of bacterial plaque. Compared with traditional methods, especially the cellar sealing treatment method using stainless steel covers or cellar cloths, the use of concentrated yellow mud water provides a more natural and safe antibacterial measure, and can also improve the stability of the microbial community during the winemaking process to a certain extent.
[0043] (2) The addition of antibacterial agents only acts on the outer surface of the sealing mud and will not interfere with the stability of the microbial community inside the sealing mud. This design ensures that the intrinsic quality of the sealing mud is not damaged, and the microbial community can continue to play its positive role in the winemaking process, such as producing alcohol, acid, ester and other aromatic substances, and improving the flavor and quality of the wine. At the same time, external antibacterial protection can effectively avoid the appearance of surface plaque, further ensuring the stability of the wine quality after the wine cellar is closed.
[0044] (3) The coating treatment of the cellar sealing skin layer provides an additional protective layer for the cellar sealing mud. This step can effectively prevent interference from the external environment, further strengthen the sealing effect of the cellar sealing mud, avoid excessive changes in air and humidity from adversely affecting the cellar environment, and provide more stable microbial growth conditions for the winemaking process. Through this series of measures, the effect of the cellar sealing treatment is more stable, which not only helps to increase the yield and quality of the wine, but also reduces the quality fluctuations caused by changes in the external environment.
[0045] In summary, the cellar sealing treatment method provided in this application, through the innovative combination of cleaning, antibacterial, cellar dragging and coating layer treatment, provides an efficient, stable solution that can improve the quality of wine cellar management, effectively avoids the problem of bacterial plaque, and improves the sealing of the cellar sealing mud and the quality of the wine body.

Obviously, the drawings described below are some implementation methods of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.
[0047] Figure 1 It is a schematic flow chart of the sealing method of a wine cellar in an embodiment of the present application. DETAILED DESCRIPTION
[0048] The embodiments of the present invention will be described in detail below in conjunction with the examples, but it will be appreciated by those skilled in the art that the following examples are only used to illustrate the present invention and should not be considered as limiting the scope of the present invention. If no specific conditions are specified in the examples, the conditions are carried out according to normal conditions or the conditions recommended by the manufacturer. If the manufacturer of the reagents or instruments used is not specified, they are all conventional products that can be obtained commercially.
[0049] refer to Figure 1 The present application provides a wine cellar sealing method, comprising:
[0050] Step S1, cleaning the original cellar mud of the wine cellar, and preparing cellar sealing mud and concentrated yellow mud aqueous solution respectively;
[0051] Step S2, using the cellar-sealing mud to perform a cellar-sealing treatment on the wine cellar, and using the concentrated yellow mud aqueous solution to perform a cellar-scratching treatment on the surface of the cellar-sealing mud after the cellar-sealing treatment, so as to form a cellar-sealing skin layer coated on the surface of the cellar-sealing mud; wherein the concentrated yellow mud aqueous solution contains a microbial inhibitory component; and / or, in the cellar-scratching treatment, spraying a microbial inhibitory solution containing the microbial inhibitory component alone;
[0052] Step S3, using a covering layer to coat the surface of the cellar sealing skin layer.
[0053] As mentioned above, cellar mud (also known as cellar skin mud) is a special soil material used to seal the cellar during the liquor brewing process. Its main function is to seal the cellar to prevent the entry of outside air and moisture, thereby providing a stable and closed environment for the growth and fermentation of microorganisms during the brewing process.
[0054] In the above-mentioned step S1, the original pit skin mud is cleaned, and the cleaning method may include:
[0055] Clean the old cellar mud in the cellar, remove the cellar mud that is aging, contaminated (including but not limited to mold, dregs, blackening, rancid odor, etc.) or no longer suitable for winemaking, and ensure the thoroughness and safety of the cleaning.
[0056] As mentioned above, after the cellar sealing mud is treated, the concentrated yellow mud aqueous solution is mainly used to coat the surface of the cellar sealing mud, that is, to form the outside of the cellar sealing skin layer.
[0057] Specifically, concentrated yellow mud water is used for cellar dragging treatment, and by coating the outer surface of the cellar sealing mud, the following purposes are achieved:
[0058] (1) Isolate from contact with air and organic matter: The coating of concentrated yellow mud water forms a protective film to prevent the organic matter inside the sealing mud from direct contact with the outside air, thereby inhibiting the invasion of external bacteria and mold, and effectively avoiding the formation of bacterial plaque on the surface of the sealing mud.
[0059] (2) Antibacterial effect: If microbial inhibitors are added to the concentrated yellow mud water, they can effectively inhibit the reproduction and growth of miscellaneous bacteria through their action on the surface of the cellar sealing mud, further ensuring the cleanliness of the surface of the cellar sealing mud and the stability of the wine cellar environment.
[0060] In short, the application of concentrated yellow mud water is mainly to strengthen the protection of the surface of the cellar sealing mud, prevent the formation of bacterial plaque, and ensure the sealing of the cellar and the stability of the fermentation environment.
[0061] In the above, in step S2, two processing methods are included, specifically including:
[0062] Method (1) The concentrated yellow mud aqueous solution contains microbial inhibition components:
[0063] In this scheme, microbial inhibitory components are added to the concentrated yellow mud water solution and coated on the surface of the cellar mud through the cellar dragging treatment. The coating formed by the concentrated yellow mud water can effectively isolate the external surface of the cellar mud from contact with the air, reduce the invasion of external moisture and microorganisms in the air into the cellar mud, and thus inhibit the growth of mold and other aerobic microorganisms. By mixing the antibacterial agent with the concentrated yellow mud water, the microbial inhibitory components can continue to inhibit the growth of miscellaneous bacteria on the cellar surface. The hydration of the concentrated yellow mud water and the antibacterial agent work together to maintain the cleanliness of the cellar surface for a long time, reduce the production of mildew and miscellaneous bacteria, and thus avoid affecting the fermentation process and the quality of the wine.
[0064] In addition, the thick yellow mud water itself has good sealing properties. Through its coating, the sealing effect of the cellar mud is further enhanced, while maintaining the stability of the internal environment of the cellar, which helps to improve the fermentation quality and taste of the wine.
[0065] Method (2) Spraying the microbial inhibition solution containing microbial inhibition components alone:
[0066] In this solution, the microbial inhibitor solution is sprayed on the outer surface of the sealing mud alone. The spraying treatment can accurately apply the antimicrobial agent directly to the surface of the sealing mud, especially in areas with high humidity or mold growth. The spraying method is flexible, and the spraying amount and spraying frequency can be adjusted as needed to ensure sufficient antimicrobial effect at critical moments. Compared with the cellar dragging treatment of concentrated yellow mud water, spraying the antimicrobial solution can deal with local plaque problems more quickly, avoiding mold growth caused by excessive humidity or temperature changes, especially when the seasons change or the environment changes greatly.
[0067] Since the microbial inhibition solution only acts on the outer surface of the sealing mud and does not enter the interior of the soil, it does not interfere with the microbial community inside the sealing mud and can maintain the balance of microorganisms and the health of the fermentation environment.
[0068] Method (1) can form a continuous protective layer on the surface of the sealing mud by using an antibacterial agent together with a concentrated yellow mud aqueous solution, which can effectively inhibit the formation of bacterial plaque and avoid the trouble of frequent treatment. It is suitable for long-term management after the entire cellar is sealed. Method (2) focuses on local precise control and is particularly suitable for microbial problems that arise during the cellar sealing process or in the early stages of fermentation. It can respond flexibly in the late stage of cellar sealing or in high humidity environments, and has a good ability to deal with temporary mildew problems or bacterial plaque in certain special areas.
[0069] The two methods are not mutually exclusive. In fact, they can be used in combination according to different actual conditions to maximize the inhibition of plaque formation and ensure the stability of the microbial community during the winemaking process, which is conducive to improving the quality and stability of the wine.
[0070] It should be noted that microbial inhibition components can be added to concentrated yellow mud water or clean water, and the solution containing potassium pyrosulfite can be sprayed or covered on the surface of the cellar sealing mud through a sprayer or mop to prevent bacterial plaque from forming on the surface of the cellar sealing mud. In addition, other methods can be used, the core of which is to apply the solution or mixture of potassium pyrosulfite to the outer surface of the cellar sealing mud (cellar cap), and these methods can prevent the growth of bacterial plaque on the surface of the cellar sealing mud.
[0071] During the cellar cleaning and dragging process, potassium metabisulfite can be added to the concentrated yellow mud water and covered on the outer surface of the cellar sealing mud by dragging the cellar. The prepared potassium metabisulfite solution can be sprayed on the outer surface of the cellar sealing mud. These two methods can be used alternately. In case of work errors and the potassium metabisulfite added to the concentrated yellow mud water fails to meet the requirements, the potassium metabisulfite solution can be sprayed on the outer surface of the cellar sealing mud to compensate.
[0072] In summary, in this embodiment, the microbial inhibitor potassium metabisulfite can also be prepared into a solution and sprayed on the outer surface of the cellar-sealing mud with a sprayer, which is implemented separately from the cellar-dragging process with concentrated yellow mud water. The specific operation method can be selected according to the actual situation, whether to add it into the concentrated yellow mud water to drag the cellar, or to spray it on the outer surface of the cellar-sealing mud with a sprayer. The implementation method can be flexibly selected according to the actual situation, and even the two methods can be flexibly combined for use.
[0073] In the above, the surface of the cellar sealing layer is coated with a covering layer, wherein the covering layer can be a non-toxic plastic film or a chemical fiber cellar special cloth or other materials.
[0074] In order to prevent the cellar skin from drying out and cracking due to rapid evaporation of moisture, after the cellar sealing skin layer is constructed, a layer of non-toxic plastic film or chemical fiber cellar-specific cloth is covered on the surface to form a covering layer, which can effectively keep the mud skin moisturized and prevent it from drying out and cracking.
[0075] Furthermore, in step S1, the method for preparing the cellar sealing mud comprises:
[0076] Step S11, selecting viscous soil, soaking the viscous soil in first hot water to make it flocculate or dissolve, and then obtaining a mixed mud material.
[0077] The above-mentioned sticky soil is yellow, purple or red sticky soil without impurities and pollution. Specifically, local yellow or purple sticky soil without impurities, pollution and little humus can be selected, and attention should be paid to sealing and stickiness.
[0078] After the sticky soil (such as yellow sticky soil, i.e. yellow mud) is mixed and soaked with the first hot water (such as boiling water), the particles in the yellow mud are flocculated or dissolved under the action of the first hot water, so that the hard soil clumps in the yellow mud become soft.
[0079] Put the selected sticky soil (such as yellow, purple, and red sticky soil without impurities or pollution) into the first hot water for soaking. This process can not only flocculate or dissolve the hard lumps in the soil, making the soil softer and easier to handle, but also kill the bacteria and microorganisms that may exist in it through high temperature. The core purpose of high temperature sterilization treatment is to ensure that the microbial community in the sealing mud is controlled, avoid the growth of bacteria, and ensure the stability of the microbial environment during the fermentation process.
[0080] Step S12, performing high-temperature sterilization treatment on the mixed mud material using the first hot water to obtain a sterilized mixed mud material.
[0081] As mentioned above, high temperature sterilization is carried out during the preparation of the cellar mud, with the purpose of killing bacteria, microorganisms and other undesirable components in the mixed mud by high temperature, so as to ensure that the quality of the cellar mud meets the use standards. For example, boiling water is used to ferment the cellar mud, thereby killing bacteria and weak microbial cells in the cellar mud, and rejuvenating the dominant microbial community.
[0082] The temperature of the first hot water needs to be no less than 90°C. This high temperature requirement is to ensure that potential microorganisms and bacteria in the mud are effectively killed. The higher the temperature, the faster the death rate of microorganisms. Therefore, hot water above 90°C can quickly penetrate into the soil and effectively sterilize bacteria, fungi and other microorganisms in the soil.
[0083] During the high-temperature sterilization process, the first hot water heating is used. In this step, the raw cellar mud is mixed with boiling water (temperature not less than 90°C) and subjected to high-temperature heating treatment. The high temperature of boiling water can effectively kill the miscellaneous bacteria and weak microorganisms in the cellar mud, especially the possible pathogens, molds and other microorganisms that are not conducive to the fermentation of liquor, thereby providing a cleaner and more stable microbial environment for the subsequent brewing process. The first hot water treatment not only kills bad microorganisms, but also promotes the rejuvenation of the dominant microbial community in the cellar mud to a certain extent. After high-temperature treatment, the high-quality microorganisms in the cellar mud are protected, and the harmful microorganisms are eliminated, which can ensure that the active microbial community in the cellar mud has a positive effect on the fermentation process of liquor and promotes the production of aromatic substances in the winemaking process.
[0084] The high temperature of the first hot water can ensure that the bacteria, molds and other microorganisms that may exist in the mud are quickly killed, ensuring that the mud is clean and suitable for the growth of microbial communities. This step is completely consistent with the above-mentioned high-temperature sterilization treatment, and its purpose is to eliminate potential sources of contamination and stabilize the fermentation process.
[0085] In addition, the step of fermenting the cellar mud with boiling water not only removes the bacteria, but also ensures the wetness and flexibility of the mud through temperature regulation, laying the foundation for the subsequent cellar sealing treatment. After this step, the texture of the cellar mud is more suitable for the needs of wine fermentation.
[0086] Step S13, using a beating device to process the sterilized mixed mud material until it is soft and cooked, thus obtaining the cellar-sealing mud.
[0087] As mentioned above, the beating equipment, that is, the equipment for beating the cellar skin mud, is a kind of equipment specially used to process soil materials, and is often used to break up, mix and adjust the physical properties of the mud. For the production of cellar sealing mud, the main functions of the beating equipment include: stirring the sterilized mixed mud to evenly distribute its internal components, avoiding any lumps or uneven mud clumps, and ensuring that the cellar sealing mud has a consistent texture; through proper beating, the wetness and viscosity of the mud can be controlled to meet the standards required for cellar sealing - that is, "wet but not thin" and without hard lumps of dry mud; the beating equipment uses mechanized power to make the mud softer and without gaps, thereby enhancing its sealing effect. This process is called "beating to softness", which means that the texture of the mud has reached a level that can fit tightly to the surface of the wine cellar, and at the same time it is not too wet or dry.
[0088] The above-mentioned beating until soft and mature means that the clay material reaches certain physical properties through the processing of the beating equipment, including:
[0089] (1) No lumps: The hard soil lumps in the mud are broken up and there are no large pieces of dry mud, ensuring the uniformity and density of the sealing mud.
[0090] (2) Moist but not watery: The moisture content of the sealing mud should be moderate, neither too dry nor too wet, maintaining appropriate viscosity and workability.
[0091] (3) No gaps: After being beaten, the mud can fit tightly onto the surface of the wine cellar, forming a tight closed layer to ensure a good sealing effect.
[0092] The "beating" step ensures that the sterilized mixed mud becomes softer and has good sealing properties. This is one of the key steps in preparing the sealing mud, ensuring that the sealing mud can effectively cover the surface of the wine cellar and achieve the effect of sealing and antibacterial. At the same time, this process also provides the basis for the subsequent sealing operation to provide appropriate materials and ensure the stability of the winemaking environment.
[0093] In short, the "beating equipment" in step S13 is used to further process the sterilized mixed mud material to make it soft and suitable for cellar sealing. By "beating until soft and mature", the final cellar sealing mud will have the required wetness, softness, viscosity and density, ensuring that it can provide an ideal sealing effect during the cellar sealing process.
[0094] Furthermore, in step S1, the method for preparing the concentrated yellow mud aqueous solution comprises:
[0095] Step S14, taking yellow clay, drying it and then crushing it to obtain clay particles.
[0096] The yellow clay mentioned above may be slightly acidic yellow clay that is golden yellow, has strong viscosity, contains less sand, and contains less heavy metal ions such as iron and calcium.
[0097] The above-mentioned drying process can be natural drying in the sun, or drying by a drying device, so as to obtain clay particles.
[0098] As mentioned above, the yellow clay can be crushed by crushing equipment or manually to obtain clay particles. The particles can be in a fine powder state.
[0099] Step S15, using the clay particles to prepare the concentrated yellow mud aqueous solution.
[0100] Furthermore, the step S15, using the clay particles to prepare the concentrated yellow mud aqueous solution, comprises:
[0101] Step S151, adding a second hot water to the clay particles, sealing and soaking for no less than 24 hours, to obtain the concentrated yellow mud aqueous solution in a slurry state.
[0102] The second hot water can be prepared at different more suitable temperatures according to different seasons. Specifically, in winter, water at a temperature not lower than 90° C. is used; in seasons other than winter, water at a temperature not lower than 85° C. is used.
[0103] The mass ratio of the clay particles to the second hot water is (1.3-3): 1. For example, the mass ratio may be 1.3: 1, 1.5: 1, 2: 1, 2.5: 1, 3: 1, and the like.
[0104] Furthermore, the step S151, adding a second hot water to the clay particles, sealing and soaking for no less than 24 hours to obtain the slurry-like concentrated yellow mud aqueous solution, further comprises:
[0105] Method (1): adding the microbial inhibitory component in an amount of 0.1 to 5 weight fraction to the concentrated yellow mud aqueous solution;
[0106] Method (2): The weight fraction of the microorganism inhibitory component contained in the microorganism inhibitory solution is 0.1 to 5.
[0107] In the above, two methods are provided to add microorganism inhibition components, wherein the microorganism inhibition component may include potassium pyrosulfite.
[0108] Furthermore, the concentration of the microbial inhibitory components in the concentrated yellow mud aqueous solution, and the concentration of the microbial inhibitory components in the microbial inhibitory solution, are positively correlated with the temperature of the weather and the organic matter content in the cellar-sealing mud.
[0109] For example, in method (1), if the weather temperature is high, more of the microbial inhibitory component can be added, and if the weather temperature is low, less of the microbial inhibitory component can be added; if the sealing mud is rich in organic matter and microbial communities, more of the microbial inhibitory component can be added, and if the sealing mud is low in organic matter, the amount of the microbial inhibitory component such as potassium metabisulfite can be reduced.
[0110] For example, in method (2), the concentration of the potassium pyrosulfite solution is increased when the weather temperature is high, and the concentration of the potassium pyrosulfite solution is reduced when the weather temperature is low; and the concentration of the potassium pyrosulfite solution is increased when the sealing mud is rich in organic matter and microbial communities, and the concentration of the potassium pyrosulfite solution is reduced when the sealing mud is low in organic matter.
[0111] Furthermore, the cellar dragging process in step S2 includes:
[0112] Step S21, within the first to eleventh day after the cellar sealing treatment, the concentrated yellow mud aqueous solution is applied to the outer surface of the cellar cap of the cellar using a cellar dragging tool every day to form a protective film layer.
[0113] From the first day to the third day, the cellar is cleaned at least once with a wooden trowel; wherein the cellar cleaning includes: cleaning the cellar sealing mud with the wooden trowel, and beating the deformed part of the cellar with a wooden palm. The wooden trowel, also known as the mud trowel, is a construction tool used for surface treatment of materials such as plastering, mortar, and cement.
[0114] As mentioned above, the cellar should be mopped with thick yellow mud water once a day from 1 to 11 days after sealing, and the cellar should be cleaned once with a wooden trowel in the first three days. If the cellar is deformed, use a wooden palm to pat the cellar to avoid empty layers, depressions and cracks in the cellar. If the cellar is sunken or collapsed, the cellar should be cut and repaired in time to maintain the cellar shape and keep it aligned horizontally and vertically with the surrounding cellars. And clean the cellar every day. Among them, the wooden palm, also known as the mud palm, is a traditional hand tool, mainly used in construction or mud and water operations, especially a tool for smearing, leveling or roughening walls, floors and other building surfaces.
[0115] The cellar dragging is to use a tool (such as a mop) to evenly cover the concentrated yellow mud water solution on the outer surface of the cellar cap of the cellar, forming a layer of concentrated yellow mud water slurry protective film on the outer surface of the cellar cap to keep the outer surface of the cellar cap moisturized and prevent the cellar cap from drying and cracking.
[0116] The cellar cleaning is to clean the cellar sealing mud with a wooden trowel, and to pat the deformed cellar parts with a wooden palm to avoid empty layers, depressions and cracks in the cellar, and at the same time to promptly cut and repair the sunken and collapsed cellar caps to maintain the cellar shape and keep it horizontally and vertically aligned with the surrounding cellars.
[0117] Furthermore, the step S3, after coating the surface of the cellar sealing skin layer with a covering layer, further comprises:
[0118] Step S4, checking the cellar for deformation every day;
[0119] Step S5: If the cellar is deformed, use a wooden shovel to flatten the deformed part of the cellar.
[0120] As mentioned above, the cellars should be inspected every day, specifically to check for any deformation. If the cellars are deformed, they should be flattened with a wooden paddle in time. Damaged films should be replaced in time. The cellar surface hygiene should be inspected every day and cleaned every week.
[0121] The present invention is further described below by means of specific examples, but it should be understood that these examples are only used for more detailed description and should not be construed as limiting the present invention in any form.
[0122] Example 1
[0123] In this embodiment, the preparation and subsequent management of the cellar sealing mud with a fixed addition ratio of microbial inhibitors in the hot season were carried out.
[0124] 1. Experimental methods:
[0125] (1) Environmental conditions: Hot season temperature: 20-32℃.
[0126] (2) Preparation of sealing mud:
[0127] A. Clean the old cellar skin mud: Clean the old cellar skin mud in the cellar, remove the cellar skin mud that is aging, contaminated (mildew, with dregs, blackened, with a rancid smell, etc.) or no longer suitable for winemaking, and ensure the thoroughness and safety of the cleaning of the old cellar skin mud.
[0128] B. Use boiling water to soften the cellar mud: Use boiling water to soften the old cellar mud that has been cleaned.
[0129] C Add high-quality yellow mud: Choose local yellow or purple-red sticky soil that is free of debris, pollution, and little humus. After breaking it, soak it in 90℃ boiling water to soften the hard lumps in the yellow mud, and add it to the old cellar skin mud that has been soaked in boiling water.
[0130] D. Add high-quality old cellar mud, old cellar mud culture solution, high-quality yellow water, ethanol, wine tails and other materials according to the proposed formula.
[0131] E. Evenly mix the processed cellar mud, yellow clay and other added materials, beat them into a soft state with a cellar mud machine, and then seal the cellar.
[0132] (3) Preparation of concentrated yellow mud water:
[0133] Select high-quality slightly acidic yellow clay that has been dried, removed from impurities and broken into pieces, pour in boiling water above 85°C, yellow clay: water = 1.8:1 (weight ratio), cover and soak for 24 hours. Add potassium pyrosulfite equal to 1 weight of the total weight of the concentrated yellow mud water to the concentrated yellow mud water, stir evenly, and make the concentrated yellow mud water into a muddy state.
[0134] (4) Cleaning and dragging the cellar:
[0135] From 1 to 11 days after sealing the cellar, use concentrated yellow mud water with 1% potassium pyrosulfite to mop the cellar once a day. Use a wooden trowel to clean the cellar once in the first three days. If the cellar is deformed, use a wooden palm to pat the cellar to avoid empty layers, depressions and cracks. If the cellar is sunken or collapsed, cut and repair the cellar in time to maintain the cellar shape and keep it aligned with the surrounding cellars horizontally and vertically. Clean the cellar every day.
[0136] (5) Covering with plastic film:
[0137] After the cellar mud has hardened and the cellar cap has taken shape after 12 days of sealing, apply a thick layer of concentrated yellow mud slurry with 2% potassium metabisulfite (yellow mud: water = 2.5:1) on the cellar cap, and tap the bottom of the cellar with a wooden palm to fix the cellar shape. Then cover the cellar mud with a layer of non-toxic plastic film or chemical fiber cellar-specific cloth to keep the mud skin moisturized and prevent it from drying out and cracking.
[0138] (6) Post-storage management of sealing mud:
[0139] Check the cellar every day for any deformation. If the cellar is deformed, flatten it with a wooden paddle in time. Damaged film should be replaced in time. Check the cellar surface hygiene every day and clean it every week.
[0140] 2. Experimental results:
[0141] After completing the above steps, on the 60th day when the mash is about to be taken out of the cellar, the outer surface of the cellar sealing mud was checked and no bacterial plaque was found.
[0142] Example 2
[0143] In this embodiment, a scheme of adding potassium metabisulfite to concentrated yellow mud water at a non-fixed ratio in the hot season was investigated.
[0144] 1. Experimental methods:
[0145] Based on Example 1, the addition ratio of potassium pyrosulfite, a microbial inhibitor, was adjusted. Since potassium pyrosulfite needs a process to decompose, the ratio of potassium pyrosulfite added to the concentrated yellow mud water in the early stage is relatively high. If potassium pyrosulfite is not added to the concentrated yellow mud water on a certain day of cellar dragging in the later stage, it can also ensure that bacterial plaque will not grow on the surface of the cellar sealing mud.
[0146] 2. Parameters of different schemes and experimental results:
[0147] The details are shown in Table 2.
[0148] Table 1. Scheme and results of adding potassium pyrosulfite to concentrated yellow mud water at non-fixed ratio for high-quality cellar sealing mud in hot season
[0149]
[0150] analyze:
[0151] (1) Potassium metabisulfite can effectively inhibit the growth of bacterial plaque on the surface of the cellar mud at different addition ratios. Whether at high or low concentrations, as long as it is properly added during the critical period after cellar sealing (the first 11 days), it can effectively prevent the formation of bacterial plaque. This shows that potassium metabisulfite, as a microbial inhibitor, has a significant effect in cellar sealing treatment.
[0152] (2) It is feasible to add potassium metabisulfite in a non-fixed ratio and it can be flexibly adjusted. In different schemes, the addition ratio of potassium metabisulfite changed significantly within 11 days after cellar sealing, but the final results showed that there was no bacterial plaque on the outer surface of the sealing mud. This shows that in the early stage of cellar sealing, the growth of bacterial plaque can be effectively controlled by flexibly adjusting the addition ratio of potassium metabisulfite without the need for fixed ratio addition. This flexibility provides greater convenience for actual operation and can be adjusted according to specific circumstances (such as weather changes, the initial state of the sealing mud, etc.).
[0153] (3) Different schemes have different addition ratios of potassium metabisulfite, but the effects are equivalent. Scheme 1: From the 1st day to the 11th day, the addition ratio of potassium metabisulfite varies between 0.5 and 2, showing a high degree of flexibility. Scheme 2: From the 1st day to the 11th day, the addition ratio of potassium metabisulfite varies between 0.2‰ and 1.5‰, with a larger range of variation, but it is equally effective. Scheme 3: From the 1st day to the 11th day, the addition ratio of potassium metabisulfite varies between 0.2 and 3, with the largest range of variation, but the effect is still good. Scheme 4: From the 1st day to the 11th day, the addition ratio of potassium metabisulfite varies between 0.1 and 5, with the widest range of variation, but it is equally effective.
[0154] (4) Post-management (such as daily inspection of cellar deformation, timely flattening, and covering with plastic film) is crucial to the sealing of the cellar mud and the quality of the wine. Although the addition of potassium metabisulfite plays a key role in the early stage of cellar sealing, post-management measures (such as daily inspection of cellar deformation, timely flattening, and covering with plastic film) are also important links to ensure the sealing of the cellar mud and the quality of the wine. These measures can effectively prevent the sealing of the cellar mud from affecting its sealing due to deformation or cracking, and further ensure the stability of the wine cellar and the quality of the wine.
[0155] Example 3
[0156] In this embodiment, a non-fixed concentration potassium pyrosulfite solution spraying scheme in the hot season was used for investigation.
[0157] 1. Experimental methods:
[0158] On the basis of Example 1, potassium pyrosulfite is not added to the concentrated yellow mud water, and there is no obvious water mark on the surface of the cellar sealing mud. The potassium pyrosulfite can be sprayed on the outer surface of the cellar sealing mud with a sprayer to inhibit the reproduction of aerobic microorganisms on the outer surface of the cellar sealing mud and prevent bacterial plaque from growing on the surface of the cellar sealing mud. Since potassium pyrosulfite has a decomposition process, the potassium pyrosulfite solution sprayed in the early stage has a high concentration, and the potassium pyrosulfite solution may not be sprayed in some days in the later stage, which can also ensure that bacterial plaque does not grow on the surface of the cellar sealing mud.
[0159] 2. Parameters of different schemes and experimental results:
[0160] The details are shown in Table 2.
[0161] Table 2. Spraying scheme and results of non-fixed concentration potassium metabisulfite solution for high-quality cellar mud in hot season
[0162]
[0163] Example 4
[0164] In this embodiment, a scheme of adding potassium metabisulfite to non-high-quality pit mud in hot season was investigated.
[0165] It should be noted that the organic matter content in ordinary cellar mud is not only lower than that in high-quality cellar mud, but also has far fewer types. The possibility of bacterial plaque growth on the surface of the cellar mud is much smaller, so the amount of potassium metabisulfite used can also be slightly reduced.
[0166] Experimental results:
[0167] The details are shown in Table 3.
[0168] Table 3. Potassium pyrosulfite addition scheme and results for non-high-quality cellar mud in hot season
[0169]
[0170] analyze:
[0171] Spraying potassium metabisulfite solution at different concentrations can effectively inhibit the growth of bacterial plaque on the surface of the cellar mud. Spraying potassium metabisulfite solution at non-fixed concentrations is feasible and can be flexibly adjusted according to specific circumstances. Different schemes differ in the concentration of spraying potassium metabisulfite solution, but the effects are equivalent and can effectively prevent the formation of bacterial plaque. Post-management measures (such as daily inspection of cellar deformation, timely flattening, covering with plastic film, etc.) are crucial to the sealing of the cellar mud and the quality of the wine. These conclusions provide an important reference for cellar sealing in actual production, which helps to improve the management quality of wine cellars and ensure the quality and stability of the wine.
[0172] Example 5
[0173] In this example, the preparation and subsequent management of the cellar sealing mud with a fixed potassium metabisulfite addition ratio in winter were investigated.

[0178] B. Use boiling water to soften the cellar mud: Use boiling water to soften the old cellar mud that has been cleaned.
[0179] C Add high-quality yellow mud: Choose local yellow or purple-red sticky soil that is free of debris, pollution, and little humus. After breaking it, soak it in boiling water above 90℃ to soften the hard soil lumps in the yellow mud, and add it to the old cellar skin mud that has been soaked in boiling water.
[0180] D. Add high-quality old cellar mud, old cellar mud culture solution, high-quality yellow water, ethanol, wine tails and other materials according to the proposed formula.
[0181] E. Evenly mix the processed cellar mud, yellow clay and other added materials, beat them into a soft state with a cellar mud machine, and then seal the cellar.
[0182] (3) Preparation of concentrated yellow mud water: Select high-quality slightly acidic yellow clay that has been dried, removed from impurities and broken into pieces, pour into boiling water above 90°C, yellow mud: water = 2:1 (weight ratio), cover and soak for 24 hours. Add 0.5% of the total weight of concentrated yellow mud water potassium pyrosulfite to the concentrated yellow mud water, stir evenly, and make the concentrated yellow mud water into a muddy state.
[0183] (4) Cleaning and mopping the cellar: mop the cellar once a day with concentrated yellow mud water with 0.5% potassium pyrosulfite added from 1 to 11 days after sealing the cellar. Use a wooden trowel to clean the cellar once in the first three days. If the cellar is deformed, pat the cellar with a wooden palm to avoid empty layers, depressions and cracks. If the cellar is sunken or collapsed, cut and repair the cellar in time to maintain the cellar shape and keep it aligned with the surrounding cellars horizontally and vertically. Clean the cellar every day.
[0184] (5) Covering with plastic film: After the cellar mud has hardened and the cellar cap has taken shape after 12 days of sealing, apply a thick layer of concentrated yellow mud slurry (yellow mud: water = 2.5:1) with 1% potassium metabisulfite added to the cellar cap, and tap the bottom of the cellar with a wooden palm to fix the cellar shape. Then cover the cellar mud with a layer of non-toxic plastic film or chemical fiber cellar-specific cloth to keep the mud skin moisturized and prevent it from drying out and cracking.
[0185] (6) Post-storage management of sealing mud:
[0186] Check the cellar every day for any deformation. If the cellar is deformed, flatten it with a wooden paddle in time. Damaged film should be replaced in time. Check the cellar surface hygiene every day and clean it every week.
[0187] 2. Experimental results:
[0188] After completing the above steps, on the 60th day when the mash is about to be taken out of the cellar, the outer surface of the cellar sealing mud was checked and no bacterial plaque was found.
[0189] Example 6
[0190] In this embodiment, a scheme of adding potassium metabisulfite to concentrated yellow mud water at a non-fixed ratio in the cold season was investigated.
[0191] 1. Experimental method: Based on Example 5, the addition ratio of the microbial inhibitor potassium pyrosulfite was adjusted, with specific reference to Table 4.

[0193] Table 4. Scheme and results of adding potassium pyrosulfite to concentrated yellow mud water at a non-fixed ratio for high-quality cold-season cellar sealing mud
[0194]
[0195] Through the experimental results of Example 6, the following conclusions can be drawn: Potassium metabisulfite can effectively inhibit the growth of bacterial plaque on the surface of the cellar mud at different addition ratios. It is feasible to add potassium metabisulfite in a non-fixed ratio, and it can be flexibly adjusted according to the specific situation. Different schemes differ in the addition ratio of potassium metabisulfite, but the effects are equivalent, and they can effectively prevent the formation of bacterial plaque. Post-management measures (such as checking the deformation of the cellar every day, leveling it in time, covering it with plastic film, etc.) are crucial to the sealing of the cellar mud and the quality of the wine. These conclusions provide an important reference for the cellar sealing process in actual production, which helps to improve the management quality of the wine cellar and ensure the high quality and stability of the wine.

[0197] In this example, a spraying scheme of potassium pyrosulfite solution with non-fixed concentration in the cold season was investigated.
[0198] 1. Experimental methods:

The potassium metabisulfite can be sprayed onto the outer surface of the cellar-sealing mud with a sprayer to inhibit the reproduction of aerobic microorganisms on the outer surface of the cellar-sealing mud and avoid the growth of bacterial plaque on the surface of the cellar-sealing mud. Please refer to Table 5 for details.

[0206] 1. Experimental methods:
