Description

Technical Field

[0001] The utility model relates to the technical field of wine making, in particular to a mud-sealed cellar structure used in a manual wine making workshop. Background Art

[0002] In the process of brewing liquor, fermentation is an essential and important step. The solid-state method is the most commonly used fermentation method for brewing liquor, especially high-quality liquor. The process must provide a sealed fermentation environment to ensure anaerobic fermentation of the mash, which can not only avoid the waste of raw materials caused by the aerobic respiration of yeast consuming fermentable sugars, but also prevent harmful bacteria from invading the cellar and affecting the fermentation; in addition, the unique flavor substances of Luzhou-flavor liquor also rely on the participation of anaerobic functional bacteria in the cellar mud, and the sealed fermentation environment is also conducive to the domestication and enrichment of these bacteria.

[0003] The sealing of the cellar is the basis for ensuring the anaerobic fermentation environment. The traditional cellar sealing method is to wait for the mash to form a mash cap after entering the cellar, step on it tightly and pat it clean, then evenly spread a layer of Daqu on its surface, and then manually evenly cover it with a layer of sealing mud with a thickness of 10cm to 12cm. This cellar sealing method is called mud cellar sealing. In the process of sealing and opening the cellar, the sealing mud will be mixed with some mash and husks, which will reduce the sealing and water retention of the sealing mud in the long run, thereby shortening the service life of the sealing mud. In addition, the sealing mud is in contact with the air for a long time, and the bacteria inside multiply. After the cellar is sealed, the sealing mud is in direct contact with the mash, which affects the quality of the wine. This is one of the main reasons for the presence of foreign flavors in the base wine produced by the surface mash. Moreover, the cleaning and protection of the cellar after sealing is also relatively cumbersome. If the sealing mud is blown, cracked, or leaks air, it will directly affect the fermentation of the mash, and then affect the wine quality and yield.

[0004] In response to the shortcomings of mud cellar sealing, film cellar sealing and stainless steel sealing devices have been developed. Since the risk of plasticizers in film has been confirmed, this method has been eliminated. Due to the high density and hardness of stainless steel, stainless steel sealing devices are only suitable for modern mechanized winemaking workshops with uniform cellar shapes and sizes. For cellars with non-uniform shapes and sizes, and for winemaking workshops with traditional manual operations, the manufacturing cost of stainless steel sealing devices will increase significantly, and without mechanized assistance, it is impossible to transport large-mass stainless steel sealing devices on the production site. In addition, due to the smoothness of stainless steel itself and its difficulty in bending, there are limitations such as difficulty in the adhesion of cellar sealing mud. Utility Model Content

[0005] In order to overcome the above-mentioned shortcomings of the existing mud-sealing cellar method, the technical problem to be solved by the utility model is to provide a safer and lighter mud-sealing cellar structure for a manual wine-making workshop.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0007] The mud-sealed cellar structure used in a manual wine-making workshop comprises a mud-sealing layer covering the surface of mash in a cellar, the periphery of the mud-sealing layer being sealed to the edge of the cellar, and a cellar cover made of carbon fiber material, the shape of which matches the mash cap on the top of the mash, a cover edge being arranged around the cellar cover, the cellar cover cover being arranged on the top of the mash, the cover edge being overlapped to the edge of the cellar, and the mud-sealing layer covering the outer surface of the cellar cover.

[0008] Furthermore, the outer edge of the cellar cover covering the mash exceeds the cellar edge by at least 5 cm.

[0009] Furthermore, the width of the cover edge is 10-12 cm, which is the same as the thickness of the mud sealing layer.

[0010] Furthermore, densely distributed serrated grooves are provided on the outer surfaces of the cellar cover and the cover edge.

[0011] The beneficial effects of the utility model are as follows: by arranging a cellar cover made of carbon fiber material between the mash and the mud sealing layer, cracking of the cellar sealing mud caused by blowing and falling heads formed during the fermentation process can be avoided, harmful bacteria can be prevented from invading the mash to a certain extent, the sealing during the fermentation process can be enhanced, and the situation in which mud and water seep into and pollute the mash during daily cellar maintenance can be avoided; the cellar cover made of carbon fiber material is light in weight, high in strength, and strong in plasticity, and can be made into cellar covers of different irregular shapes according to the irregular-shaped cellars of traditional manual wine-making workshops, is easy to seal, and can be manually carried inside the workshop and recycled, which is convenient and quick.

[0016] The utility model is further described below in conjunction with the accompanying drawings.

[0017] It should be noted that if there are directional indication terms in the present invention, such as up, down, left, right, front, and back directions and orientation terms, they are for the purpose of facilitating the description of the relative position relationship between components, and are not for the absolute position of the related components or the position relationship between components. They are only used to explain the relative position relationship and movement of the components in a certain posture. If the specific posture changes, the directional indication will also change accordingly. If there are terms related to quantity in the present invention, such as "multiple", "multiple", "several", etc., they specifically refer to two or more.

[0018] like Figure 1-3 As shown, the mud-sealed cellar structure for a manual wine-making workshop of the utility model comprises a mud-sealing layer 3 covering the surface of the mash 2 in the cellar 1, the periphery of the mud-sealing layer 3 is sealed with the edge of the cellar 1, and also comprises a cellar cover 4 made of carbon fiber material, the shape of the cellar cover 4 matches the mash cap on the top of the mash 2, a cover edge 5 is arranged around the cellar cover 4, the cellar cover 4 is covered on the top of the mash 2, the cover edge 5 overlaps the edge of the cellar 1, and the mud-sealing layer 3 covers the outer surface of the cellar cover 4.

[0019] The use process of the utility model is as follows: when sealing the cellar, first check the quality and sanitary conditions of the mash 2, and after confirming that it is qualified, step on and pat the mash cap part on the top of the mash 2 according to the process requirements, and evenly sprinkle a layer of Daqu powder on the mash cap after stepping and patting to form it, and then cover the mash cap tightly with the cellar cover 4, and the cover edge 5 needs to be completely overlapped on the edge of the cellar 1. After confirming the seal, pour a sufficient amount of cellar sealing mud on the cellar cover 4, and evenly spread the cellar sealing mud to cover the entire cellar cover 4 to form a mud sealing layer 3, and the edge of the mud sealing layer 3 needs to exceed the edge of the cover edge 5.

[0020] The utility model can enhance the structural strength of the mud sealing layer 3 to a certain extent by adding a cellar cover 4 made of carbon fiber material between the fermented mash 2 and the mud sealing layer 3, and can avoid the cracking of the mud sealing layer 3 caused by the blowing mouth and the falling head formed during the fermentation process. At the same time, the fermented mash 2 is separated from the mud sealing layer 3, which can prevent muddy water from penetrating into and polluting the fermented mash 2, and can also prevent the fermented mash 2 from mixing into the mud sealing layer 3 and affecting the sealing and water retention of the cellar mud. The reason why carbon fiber is used to make the cellar cover 4 is that the carbon fiber material is relatively stable and will not bring in pollutants to affect the fermented mash 2. The material has strong plasticity and can be made into a shape that matches the fermented mash cap. At the same time, the overall rigidity is not high, and it is easy to ensure the sealing of its periphery and the edge of the cellar 1 under the compression of the mud sealing layer 3. In addition, the material is light in texture and can be convenient for manual handling and recycling.

[0021] When designing the cellar cover 4, in order to ensure that the cellar cover 4 can completely seal the mash 2, the outer edge of the cellar cover 4 covering the mash 2 should exceed the cellar ridge of the cellar pit 1 by at least 5 cm. The cellar ridge is the inner edge of the cellar pit 1. The edge of the cellar cover 4 exceeds the inner edge of the cellar pit 1, which can prevent the edge of the cellar cover 4 from pressing on the mash 2, causing a gap between the cover edge 5 and the edge of the cellar pit 1, and affecting the sealing effect.

[0022] When designing the cover edge 5, the preferred solution is that the width of the cover edge 5 is 10-12 cm, which is the same as the thickness of the mud sealing layer 3. In this way, when laying the mud sealing layer 3, workers can control the laying thickness of the cellar sealing mud according to the width of the cover edge 5, which is conducive to the mud cellar sealing operation to meet the process requirements. As for the thickness of the cellar cover 4 and the cover edge 5, they are designed according to the size of the cellar 1, and the structural strength is sufficient to ensure that the cellar cover 4 does not deform when placed.

[0023] Furthermore, densely distributed serrated grooves 6 are provided on the outer surfaces of the cellar cover 4 and the cover edge 5. The purpose of providing the serrated grooves 6 is to enable the cellar sealing mud to better adhere to the outer surfaces of the cellar cover 4 and the cover edge 5, while reducing the cracking of the mud sealing layer 3, enhancing the sealing during the fermentation process, and helping to increase the wine yield and improve the quality of the wine.

[0024] The utility model arranges a cellar cover 4 made of carbon fiber material between the mash 2 and the mud sealing layer 3, so as to avoid cracking of the cellar sealing mud caused by blowing and falling heads formed in the fermentation process, prevent harmful bacteria from invading the mash 2 to a certain extent, enhance the sealing performance in the fermentation process, and also avoid the situation in which mud and water penetrate into and pollute the mash 2 during daily cellar maintenance; the cellar cover 4 made of carbon fiber material is light in weight, high in strength, and strong in plasticity, and can be made into cellar covers 4 of different irregular shapes according to the irregular-shaped cellars 1 of traditional manual wine-making workshops, so as to easily ensure the sealing effect, and can be manually carried and recycled in the workshop, which is convenient and fast, and has good practicality and application value.
