Description

TECHNICAL FIELD

[0001] The utility model relates to food processing equipment field, concretely is a stainless steel cover cellar. BACKGROUND

[0002] In the brewing process of baijiu, it is necessary to seal the fermented grains into a pit cellar so that microorganisms can grow and reproduce better in an anaerobic environment. However, the traditional pit sealing with mud has the problems of poor on-site hygiene, high labor intensity of employees, moldy and heavy odor of the fermented grains, and other common industry problems.

[0003] Meanwhile, in the process of saccharification and fermentation, yeast converts sugar into alcohol and carbon dioxide. The carbon dioxide is continuously produced and accumulated in the cellar, causing the pressure in the cellar to gradually increase, which affects the activity of enzymes and the stability and quality of fermentation. In the prior art, in order to avoid the influence of excessive carbon dioxide on the saccharification and fermentation process, an exhaust hole is reserved when using a stainless steel cover to seal the cellar. The exhaust hole is manually opened to exhaust air after a certain period of sealing. However, due to the large number of cellars, it is difficult to supervise and manage, which occupies a large number of human resources and causes misplacement and leakage of exhaust air, affecting the quality and yield of the final baijiu. SUMMARY

[0004] To solve the above problems, the utility model provides a stainless steel cover cellar, which realizes automatic exhaust to avoid misplacement and leakage, and stabilizes the quality and yield of baijiu.

[0005] The utility model provides a stainless steel cover cellar, which comprises a cellar body with an open top, a cellar sealing cover covering the opening, and a one-way exhaust valve penetrating through the sealing cover and communicating with the inside of the cellar body. The one-way exhaust valve comprises an air inlet pipe with one end penetratingly fixed to the sealing cover and the other end forming an expanded section, an exhaust pipe with a diameter larger than that of the air inlet pipe, one end of the exhaust pipe being connected to the expanded section with a larger diameter, and a floating ball arranged in the expanded section and having a diameter larger than that of the air inlet pipe and smaller than that of the exhaust pipe.

[0006] According to the technical scheme, in the brewing process, carbon dioxide and other gases are continuously produced in the cellar body and enter the one-way exhaust valve through the air inlet pipe. When the air pressure in the cellar body and the exhaust pipe is less than the sum of the atmospheric pressure and the gravity of the floating ball, the floating ball is in a closed position. At this time, the floating ball abuts against the expanded section to form a sealed environment in the inside of the cellar body. When the air pressure in the cellar body and the exhaust pipe is greater than the sum of the atmospheric pressure and the gravity of the floating ball, the floating ball rises, the gas passage is opened, and automatic exhaust of the stainless steel cover cellar is realized. This avoids the problems of misplacement and leakage that may occur in manual exhaust. At the same time, the automatic exhaust mode also makes the exhaust of the stainless steel cover cellar more flexible, ultimately ensuring the stability of the quality and yield of baijiu.

[0007] In an optional technical solution, the one-way exhaust valve further comprises a sealing plate arranged at one end of the exhaust pipe away from the flared section; and the opening is arranged at the exhaust hole of the sealing plate.

[0008] According to the technical solution, by arranging the sealing plate at one end of the exhaust pipe away from the flared section, the foreign matters are effectively blocked from entering the inner cavity of the exhaust pipe, ensuring the smoothness of the pipeline and reducing the possibility of foreign matters entering the pit body during the exhaust process, causing the pollution of the fermented grains. By arranging the exhaust hole at the opening of the sealing plate, the exhaust pipe can always be in communication with the external atmosphere, achieving the automatic exhaust of the stainless steel cover pit while blocking the foreign matters and reducing the manual supervision.

[0009] In an optional technical solution, one end of the exhaust pipe away from the flared section is a clamping assembly joint; and the sealing plate is clamped with the exhaust pipe through the clamping assembly joint.

[0010] In an optional technical solution, the one-way exhaust valve further comprises a clamp fixed with the clamping assembly joint and the sealing plate in a detachable form.

[0011] According to the technical solution, the sealing plate is clamped with the exhaust pipe through the clamping assembly joint, which can more conveniently complete the installation or dismounting of the sealing plate, ensure the circumferential sealing of the sealing plate and the exhaust pipe, facilitate the regular cleaning of the inner part of the exhaust pipe or replacement of parts, and reduce the operation and maintenance cost.

[0012] In an optional technical solution, the stainless steel cover pit further comprises an exhaust detection module connected with the exhaust hole and used for detecting the gas discharged through the exhaust hole in real time.

[0013] According to the technical solution, by arranging the exhaust detection module to detect the composition of the gas discharged from the stainless steel cover pit, the metabolic intensity of the microorganisms in the stainless steel cover pit is monitored, thereby assisting in judging the sealing property of the stainless steel cover pit, reducing the risk of oxygen infiltration to destroy the anaerobic environment or foreign matters entering the stainless steel cover pit to cause the pollution of the fermented grains.

[0014] In an optional technical solution, the stainless steel cover pit further comprises a temperature sensor arranged through the sealing pit cover and connected to the inside of the pit body.

[0015] According to the technical solution, by arranging the temperature sensor connected to the inside of the pit body to detect the temperature inside the pit body, the influence of the temperature on the activity of the microorganisms is avoided, and the exhaust condition of the stainless steel cover pit can also be monitored through the temperature change inside the pit body, reducing the loss of the wine quality and yield caused by the failure of the automatic exhaust valve.

Detailed Implementation

[0019] 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.

[0020] Figure 1 This is a schematic diagram of the structure of the stainless steel covered cellar 100 provided in the embodiments of this application. Figure 2 This is an enlarged structural schematic diagram of the one-way exhaust valve provided in the embodiments of this application, with reference to... Figure 1 and Figure 2 As shown, the stainless steel covered cellar 100 provided in this application includes: a cellar body 101 with an open top, a cellar cover 102 covering the opening of the cellar body 101, and a one-way exhaust valve 103 penetrating the cellar cover 102 and communicating with the interior of the cellar body 101.

[0021] Among them, such as Figure 2 As shown, the one-way exhaust valve 103 consists of an inlet pipe 1031 and an exhaust pipe 1033. One end of the inlet pipe 1031 is fixed to the sealing cover 102, and the other end forms a flared section 1032. The diameter of the exhaust pipe 1033 is larger than that of the inlet pipe 1031, and it is connected to the larger diameter end of the flared section 1032. The inlet pipe 1031 is connected to the interior of the pit body 101, and the exhaust pipe 1033 is connected to the outside atmosphere. A float 1034 with a diameter larger than that of the inlet pipe 1031 and smaller than that of the exhaust pipe 1033 is also installed inside the flared section 1032. When the float 1034 abuts against the wall of the flared section 1032 under the action of gravity, a sealed space is formed between the interior of the pit body 101 and the inlet pipe 1031, preventing circulation with the outside atmosphere.

[0022] The stainless steel cover cellar pool 100 provided in the embodiments of the present application is used to place raw materials such as fermented grains into the stainless steel cover cellar pool 100, and then seal the cellar pool body 101 by the cellar cover 102. At this time, the floating ball 1034 is in abutment with the pipe wall of the flared section 1032 under the action of gravity, and is in a closed position. External air cannot enter the inside of the cellar pool body 101 through the exhaust valve, thereby providing a good growth space for anaerobic bacteria and inhibiting the growth and reproduction of mold and other aerobic bacteria.

[0023] Microbial metabolism releases a large amount of carbon dioxide. In the process of brewing fermentation, the large amount of carbon dioxide continuously released causes the internal gas pressure of the cellar pool body 101 to rise. When the internal gas pressure of the cellar pool body 101 rises to the sum of the atmospheric pressure and the gravity of the floating ball 1034, the gas in the cellar pool body 101 lifts the floating ball 1034 away from the closed position. At this time, the inside of the cellar pool body 101 no longer forms a sealed space, and the internal gas pressure of the cellar pool body 101 is greater than the external atmospheric pressure. Under the action of the pressure difference, the carbon dioxide and other gases accumulated in the cellar pool body 101 are discharged from the stainless steel cover cellar pool 100 through the one-way exhaust valve 103, so that the internal pressure of the cellar pool body 101 is reduced. When the internal pressure of the cellar pool body 101 is reduced to below the rated pressure, the floating ball 1034 returns to the closed position under the action of gravity, and the inside of the cellar pool body 101 forms a sealed space again.

[0024] Through the above-mentioned embodiments, in the process of brewing fermentation, if the internal gas pressure of the cellar pool body 101 is greater than the sum of the atmospheric pressure and the gravity of the floating ball 1034, the floating ball 1034 in the one-way exhaust valve 103 is lifted by the internal gas pressure of the cellar pool body 101. At this time, the inside of the cellar pool body 101 is under positive pressure, and the accumulated carbon dioxide and other gases are discharged to the outside of the stainless steel cover cellar pool 100 through the one-way exhaust valve 103, so that the carbon dioxide in the cellar pool body 101 can be discharged in time, avoiding the problem of affecting the fermentation quality and liquor yield caused by the excessive internal pressure or high carbon dioxide concentration of the cellar pool body 101. At the same time, the one-way exhaust valve 103 realizes automatic exhaust under the action of the pressure difference between the inside and outside of the stainless steel cover cellar pool 100, so that the sulfides, aldehydes and other undesirable volatile substances in the inside of the cellar pool body 101 are discharged from the stainless steel cover cellar pool 100 in time, reducing the possibility of producing odors during the fermentation process of the liquor body, further stabilizing the liquor yield, and avoiding the wrong discharge and leakage caused by manual exhaust through the reserved exhaust hole 1036.

[0025] When the air pressure inside the cellar body 101 is lower than the sum of the atmospheric pressure and the gravity of the floating ball 1034, the floating ball 1034 returns to the closed position, forming a sealed space inside the cellar body 101 again, and isolating the outside atmosphere, avoiding a large amount of oxygen and other gases entering the inside of the cellar body 101, and ensuring the stability of the wine quality and yield. The above-mentioned embodiments also realize automatic exhaust and automatic closing of the exhaust valve, without the need for manual opening and closing of the reserved exhaust hole 1036, freeing human resources, and also avoiding the problems of excessive pressure inside the cellar body 101 caused by incorrect or incomplete exhaust, and a large amount of external air entering the inside of the cellar body 101 due to failure to close the exhaust hole 1036 in time, thereby improving the yield of the wine quality. At the same time, it also reduces the loss of volatile flavor substances such as alcohol and lipids caused by long-term opening of the reserved exhaust hole 1036 or exhaust valve, and ensures the richness of the wine yield and body flavor.

[0026] As a preferred embodiment of the present application, the end of the exhaust pipe 1033 away from the flared section 1032 is also provided with a sealing plate 1035, and the center of the sealing plate 1035 is provided with an exhaust hole 1036.

[0027] By providing the sealing plate 1035 at the end of the exhaust pipe 1033 away from the flared section 1032, the possibility of foreign matter entering the exhaust pipe 1033 and causing blockage of the exhaust pipe 1033 is reduced, further ensuring that the stainless steel cover cellar 100 can realize stable automatic exhaust, and also avoiding the problem of foreign matter entering the inside of the cellar body 101 during the exhaust process, causing pollution of the fermented grains. At the same time, the exhaust hole 1036 is provided in the center of the sealing plate 1035, so that the exhaust pipe 1033 can always be in communication with the outside atmosphere, blocking foreign matter while realizing automatic exhaust of the stainless steel cover cellar 100, reducing manual supervision.

[0028] As a preferred embodiment of the present application, the end of the exhaust pipe 1033 away from the flared section 1032 is a clasp assembly joint 1037, and the sealing plate 1035 is clamped with the exhaust pipe 1033 through the clasp assembly joint 1037. After the clasp assembly joint 1037 is clamped with the sealing plate 1035, it is further fixed by a detachable clamp 1038.

[0029] Through the above-mentioned embodiments, the clamping assembly joint 1037, the sealing plate 1035 and the clamp 1038 cooperatively form a circumferential seal, which can effectively prevent external dust, foreign matter and the like from entering the inner cavity of the exhaust pipe 1033, ensuring the smoothness of the exhaust pipe 1033, thereby further realizing stable automatic exhaust. At the same time, the clamp 1038 and the sealing plate 1035 are fixed in a clamping and detachable manner, which improves the convenience of the workers when they maintain or repair the stainless steel cover cellar 100 and the one-way exhaust valve 103. Even if foreign matter enters the exhaust pipe 1033 through the exhaust port when the stainless steel cover cellar 100 is sealed, the installation or removal of the sealing plate 1035 and the clamp 1038 can be more conveniently completed, which facilitates the regular cleaning of the inside of the exhaust pipe 1033 or the replacement of parts, and reduces the operation and maintenance cost of the stainless steel cover cellar 100.

[0030] As a preferred embodiment of the present application, the exhaust hole 1036 of the one-way exhaust valve 103 is also provided with an exhaust monitoring module (not shown in the figure), which can detect the gas discharged through the exhaust hole 1036 in real time.

[0031] Through the above-mentioned embodiments, the composition and pressure of the gas discharged from the cellar body 101 are detected in real time, the metabolic intensity of the microorganisms in the cellar body 101 is reflected by monitoring the carbon dioxide concentration in the discharged gas, and at the same time, whether the distiller's grains in the cellar body 101 are contaminated by miscellaneous bacteria is judged by monitoring whether the gas contains hydrogen sulfide or mercaptan gas. That is, whether the cellar body 101 is in a normal fermentation environment is judged according to the detected results, the temperature and humidity and other parameters in the cellar body 101 are timely adjusted and optimized, the metabolism of microorganisms is promoted, and the interference of miscellaneous bacteria is reduced, thereby further improving the quality and yield of the wine.

[0032] Although the exhaust detection module is connected with the exhaust hole 1036 in the embodiments of the present application, the present application is not limited thereto, and the exhaust detection module is arranged through the cover 102 to detect the composition and pressure of the gas in the cellar body 101 in real time, which should also be included in the protection scope of the present application.

[0033] As a preferred embodiment of the present application, the stainless steel cover cellar 100 further comprises a temperature sensor (not shown in the figure) arranged through the cover 102, which is connected to the inside of the cellar body 101 to detect the temperature in the cellar body 101 in real time.

[0034] Through the above-mentioned embodiments, the temperature sensor is arranged to detect the temperature inside the pit body 101 in real time, and the pressure inside the pit body 101 is judged according to the temperature inside the pit body 101, so as to judge the working state of the one-way exhaust valve 103, avoid the failure of the one-way exhaust valve 103 or the blockage of the exhaust pipe 1033 to cause the loss of the quality and yield of the wine. At the same time, according to the data collected by the temperature sensor, the heat preservation or cooling measures of the stainless steel cover pit 100 can be dynamically adjusted, so that the temperature inside the pit body 101 is maintained within a range conducive to the efficient metabolism of microorganisms, the fermentation efficiency is improved, and the problem of incomplete fermentation or off-flavor caused by temperature fluctuations is also reduced.

[0035] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
