Description

Technical Field

[0001] This utility model relates to the field of sheet material device technology, specifically a flexible composite functional sheet material device for wall surface treatment. Background Technology

[0002] The core of strong-aroma baijiu brewing relies on the "solid-state fermentation in mud cellars" process. The cellar walls, as the key carriers for microbial habitation and flavor substance generation, directly determine the quality of the liquor through their "microbial activity, moisture stability, and structural integrity." Functional microorganisms such as caproic acid bacteria and butyric acid bacteria that inhabit the cellar walls can metabolize and generate flavor substances such as ethyl caproate. Generally, mineral-rich yellow mud is used directly to build the cellar walls, relying on naturally enriched microorganisms to form "cellar mud microbial community".

[0003] Regarding the aforementioned technologies, the applicant believes that during the operation of traditional yellow mud cellars, fluctuations in temperature and humidity, pH imbalances, or improper cellar maintenance can easily lead to the loss of moisture through the cellar walls during fermentation. This results in a dry environment for microorganisms, a decrease in the number of microorganisms, and consequently, excessive acid production during fermentation, leading to a decrease in the alcohol yield. Utility Model Content

[0004] The purpose of this utility model is to provide a flexible composite functional sheet device for wall treatment, in order to solve the problem mentioned in the background art that when working with traditional yellow mud cellar walls, due to temperature and humidity fluctuations, pH imbalances, or improper cellar maintenance, moisture in the cellar wall is easily lost during fermentation, resulting in a dry microbial habitat, a decrease in the number of microorganisms, and thus excessive acid production and a decrease in alcohol yield.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a flexible composite functional sheet device for wall surface treatment, comprising an outer insulation layer and an inner insulation layer, wherein the inner insulation layer is disposed inside the outer insulation layer, a first degradation nutrient layer is disposed inside the inner insulation layer, and a second degradation nutrient layer is disposed inside the first degradation nutrient layer.

[0006] By adopting the above technical solution, during the fermentation process in the pit, the substrate materials of the two nutrient layers will slowly degrade with temperature. The second nutrient layer degrades first, releasing basic nutrients into the pit mud through the breathable micropores on the inside of the sheet, quickly replenishing the nutrients lost due to water loss. The first nutrient layer degrades in the middle of the degradation of the second nutrient layer, releasing targeted nutrient components to maintain the activity of microorganisms in the deep pit mud.

[0007] Preferably, the feature is that: both ends of the inner side of the outer insulation layer are provided with fixing plates, and the interior of the fixing plates is uniformly provided with reinforcing ribs.

[0008] By adopting the above technical solution, the strength of the fixing plate can be improved.

[0009] Preferably, the outer insulation layer has two layers, and the outer insulation layer is made of graphene insulation film.

[0010] By adopting the above technical solutions, the thermal insulation performance of the sheet material can be improved.

[0011] Preferably, the fixing plates are provided in two sets, and the fixing plates are symmetrically distributed about the outer insulation layer.

[0012] By adopting the above technical solution, the sheet material can be easily fixed.

[0013] Preferably, the fixing plate has uniformly spaced mounting holes inside, and an elastic support frame is provided on the inner side of the fixing plate.

[0014] By adopting the above technical solution, the thermal expansion and contraction of the cellar wall can be accommodated, allowing the sheet material to adhere to the cellar wall.

[0015] Preferably, the second degradable nutrient layer is made of a starch-chitosan composite matrix.

[0016] By adopting the above technical solution, the nutrient loss caused by moisture loss in traditional yellow mud pit walls can be quickly replenished, providing sufficient metabolic raw materials for caproic acid bacteria. On the other hand, the nutrient supply promotes the proliferation of caproic acid bacteria, thus maintaining a stable density of caproic acid bacteria in the pit mud.

[0017] Preferably, the first degradation nutrient layer is made of sodium alginate-humic acid microspheres.

[0018] By adopting the above technical solution, butyric acid bacteria can be provided with exclusive metabolic raw materials to promote their proliferation. On the other hand, B vitamins can be supplemented to maintain microbial enzyme activity and reduce the decline of the microbial community caused by nutritional deficiencies.

[0019] Preferably, the inner insulation layer is made of closed-cell flexible polyurethane foam.

[0020] By adopting the above technical solution, heat exchange between the cellar wall and the outside world is effectively blocked, avoiding temperature deviations inside the cellar caused by external temperature fluctuations.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] By installing a fixed plate, an external insulation layer, a second degradation nutrient layer, and a first degradation nutrient layer on the inner wall of the fermentation pit, the insulation layer can prevent temperature fluctuations inside the pit from causing deviations. Subsequently, when the fermentation humidity in the pit changes, the first and second degradation nutrient layers will gradually release nutrients under the influence of temperature, which can extend the activity cycle of the pit mud and significantly improve the production effect of the pit and the stability of the wine quality.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] Please see Figures 1 to 4 This embodiment provides a technical solution: a flexible composite functional sheet device for wall treatment, including an outer insulation layer 2 and an inner insulation layer 7. The outer insulation layer 2 has two layers and is made of graphene insulation film. The inner insulation layer 7 is disposed inside the outer insulation layer 2 and is made of closed-cell flexible polyurethane foam. It effectively blocks the heat exchange between the cellar wall and the outside world, and avoids the temperature deviation inside the cellar caused by external temperature fluctuations. It has a balanced moisture-proof and breathable properties, which can block the intrusion of external moisture into the cellar wall, while retaining a small amount of breathable channels, so as not to affect the weak gas exchange required for the respiration of microorganisms inside the cellar. It can also bend and fit the arc-shaped cellar wall synchronously with the sheet, and does not soften or deform after long-term contact with the cellar wall environment.

[0031] The No. 1 degradable nutrient layer 5 is bonded to the inside of the inner insulation layer 7 with food-grade environmentally friendly adhesive. The No. 1 degradable nutrient layer 5 is made of sodium alginate-humic acid microspheres, which have stronger temperature sensitivity and biodegradability, meet food-grade safety standards, and are specially loaded with butyric acid bacteria exclusive carbon source and B vitamins. The matrix has a honeycomb microstructure to achieve slow encapsulation and release of nutrients. During operation, the No. 1 degradation nutrient layer 5 adheres to the inner wall of the fermentation pit along with the sheet material, and is located outside the No. 2 degradation nutrient layer 4, forming a "stepped nutrient release" layout. When the fermentation in the pit enters the middle stage, the sodium alginate gel begins to degrade under continuous temperature, and its honeycomb microstructure gradually disintegrates, slowly releasing the butyric acid bacteria-specific nutrients loaded inside. The released nutrients penetrate into the deep layers of the pit mud through the breathable micropores on the inner side of the sheet material. On the one hand, it provides butyric acid bacteria with specific metabolic raw materials to promote their proliferation; on the other hand, it supplements B vitamins to maintain microbial enzyme activity and reduce the decline of the microbial community caused by nutrient deficiency. At the same time, this nutrient combination can also indirectly inhibit the reproduction of miscellaneous bacteria in the deep pit mud, ensuring the microecological balance of the pit mud. Ultimately, it forms a synergy with the No. 2 degradation nutrient layer 4 to achieve the full-cycle and full-depth maintenance of the activity of pit mud microorganisms, ensuring the stability and mellowness of the wine's flavor.

[0032] The second degradable nutrient layer 4 is bonded to the inside of the first degradable nutrient layer 5 with food-grade environmentally friendly adhesive. The second degradable nutrient layer 4 is made of starch-chitosan composite matrix, uniformly loaded with hexanoic acid bacteria activator and nitrogen, phosphorus and potassium micronutrients, and the matrix has micron-level pores pre-set inside to provide channels for nutrient release. During operation, the No. 2 degradation nutrient layer 4 is attached to the core microbial habitat layer on the inner wall of the fermentation pit along with the sheet material. When the pit enters the fermentation stage, the starch-chitosan composite matrix slowly undergoes enzymatic hydrolysis and swelling under the action of temperature, initiating a controllable degradation process. During the degradation process, the pores inside the matrix gradually expand, and the loaded caproic acid bacteria activator and nitrogen, phosphorus and potassium nutrients continuously permeate into the pit mud through the breathable micropores on the inner side of the sheet material. On the one hand, this quickly replenishes the nutrients lost due to moisture loss in the traditional yellow mud pit wall, providing sufficient metabolic raw materials for caproic acid bacteria. On the other hand, the nutrient supply promotes the proliferation of caproic acid bacteria, keeping the density of caproic acid bacteria in the pit mud stable. At the same time, the inhibitory effect of the nutrient layer on miscellaneous bacteria ensures that caproic acid bacteria always remain in the dominant bacterial group, ultimately laying the microbial foundation for the stable production of high-quality baijiu with high ethyl hexanoate content in the pit.

[0033] The overall effect achieved in Embodiment 1 is as follows: The second degradation nutrient layer 4, built into the device, uses a starch-chitosan composite matrix as a carrier and is loaded with caproic acid bacteria activator, nitrogen, phosphorus, and potassium micronutrients. The first degradation nutrient layer 5, composed of sodium alginate-humic acid microspheres, possesses the characteristic of "temperature-responsive controllable degradation": During the fermentation process in the pit, the matrix materials of both nutrient layers will slowly degrade with temperature—the second degradation nutrient layer 4 starts degradation before the first degradation nutrient layer 5, releasing basic nutrients to the pit mud through the breathable micropores on the inner side of the sheet, quickly replenishing the nutrients lost due to moisture loss; the first degradation nutrient layer 5 starts degradation in the middle of the second degradation nutrient layer 4, releasing targeted nutrient components to maintain the activity of deep pit mud microorganisms. Finally, through the "stepwise nutrient release" of the two nutrient layers, the activity cycle of caproic acid bacteria and butyric acid bacteria in the pit mud can be extended; at the same time, the components released by the nutrient layers can also improve the micro-ecological environment of the pit mud and inhibit the reproduction of lactic acid bacteria, acetic acid bacteria, and other miscellaneous bacteria. It effectively solves the problems of insufficient nutrient supply and decreased microbial activity in traditional cellar walls, and significantly improves the production efficiency of cellars and the stability of wine quality.

[0034] Example 2

[0035] The fixing plate 1 is fixedly connected to both ends of the inner side of the outer insulation layer 2. There are two sets of fixing plates 1. The fixing plates 1 are symmetrically distributed about the outer insulation layer 2. The reinforcing ribs 6 are fixedly connected evenly inside the fixing plate 1. The mounting holes 3 are opened inside the fixing plate 1. The elastic support frame 8 is fixedly connected to the inner side of the fixing plate 1. The elastic support frame 8 is made of stainless steel corrugated pipe and can adapt to the thermal expansion and contraction of the cellar wall.

[0036] The effect achieved by the entire second embodiment is that by inserting the installation rod into the interior of the pre-embedded part of the cellar wall through the installation hole 3, the device can be tightly installed on the inner wall of the cellar.

[0037] Working principle: By inserting the mounting rod into the interior of the pre-embedded part of the cellar wall through the mounting hole 3, the device can be tightly installed on the inner wall of the cellar.

[0038] Secondly, the device's built-in second degradation nutrient layer 4 uses a starch-chitosan composite matrix as a carrier and is loaded with hexanoic acid bacteria activator, nitrogen, phosphorus, and potassium micronutrients. The first degradation nutrient layer 5 is composed of sodium alginate-humic acid microspheres and has the characteristic of "temperature-responsive controllable degradation": during the fermentation process in the pit, the matrix materials of the two nutrient layers will slowly degrade with temperature. The second degradation nutrient layer 4 starts to degrade before the first degradation nutrient layer 5, releasing basic nutrients to the pit mud through the breathable micropores on the inside of the sheet to quickly replenish the nutrients lost due to water loss. The first degradation nutrient layer 5 starts to degrade in the middle of the degradation of the second degradation nutrient layer 4, releasing targeted nutrient components to maintain the activity of microorganisms in the deep pit mud.

[0039] Finally, through the "step-by-step nutrient release" of the two nutrient layers, the activity cycle of caproic acid bacteria and butyric acid bacteria in the cellar mud can be extended. At the same time, the components released by the nutrient layers can also improve the micro-ecological environment of the cellar mud and inhibit the reproduction of miscellaneous bacteria such as lactic acid bacteria and acetic acid bacteria. This effectively solves the problems of insufficient nutrient supply and decline in bacterial activity in traditional cellar walls, and significantly improves the production effect of the cellar and the stability of the wine quality.
