Description
Technical Field
[0001] This utility model relates to the field of brewing cellar technology, specifically a cellar with temperature control effect. Background Technology
[0002] Brewing fermentation pits are a crucial component of the fermentation vessels in the solid-state fermentation process of baijiu (Chinese liquor). They are primarily used for the saccharification and fermentation of grains. Simply put, a fermentation pit is a pit dug in the ground, into which grains are buried for saccharification and fermentation. After fermentation, the grains are dug out and distilled to obtain baijiu. The construction of fermentation pits is dependent on the terrain, soil quality, and other inherent conditions. Different types of baijiu have different requirements for their pits. For example, strong-aroma baijiu typically uses mud pits, with the bottom and sides lined with yellow mud. These pits have a rich microbial community, producing abundant aroma components such as ethyl hexanoate and ethyl butyrate. However, during grain fermentation, the temperature inside the pit is difficult to control. Usually, the temperature inside the pit is adjusted by changing the overall temperature of the workshop, but this method makes it difficult to maintain the temperature inside the pit, reducing its practicality.
[0003] For example, a brewing cellar described in patent CN221235568U includes a cellar body and a sealing structure. The cellar body is sealed by the sealing mechanism to prevent air leakage. However, when the cellar is sealed, it is difficult to regulate the temperature changes inside the cellar. This will affect the metabolism of microorganisms, the generation of alcohol and aroma substances, and the quality and flavor of the liquor during subsequent fermentation. At the same time, the existing technology does not have an anti-clogging device when it is necessary to drain the yellow water in the cellar. As a result, the fermenting grains in the cellar can easily clog the drain outlet during the yellow water drainage process, reducing the practicality of the cellar.
[0004] Based on this, a cellar with temperature control is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0026] In one embodiment, such as Figures 1-5 As shown, a fermentation tank with temperature control includes a fermentation tank 1. A sealing cover 11 is connected to the top of the fermentation tank 1. A sealing strip 14 is fixedly connected to the outer wall of the sealing cover 11. The outer wall of the sealing strip 14 is engaged with the inner wall of the fermentation tank 1. An inlet 12 is fixedly connected to the upper surface of the sealing cover 11. An outlet 13 is fixedly connected to the upper surface of the sealing cover 11 away from the inlet 12. A temperature sensor 15 is installed in the inner cavity of the fermentation tank 1. Circulation pipes 16 are evenly arranged in the inner cavity of the fermentation tank 1. The inlet of the circulation pipe 16 is inserted into the inner wall of the inlet 12. The outlet of the circulation pipe 16 is inserted into the inner wall of the outlet 13. A flow control valve 17 is installed on the inner wall of the circulation pipe 16 near the outlet 13. A stirring mechanism 2 is installed in the inner cavity of the fermentation tank 1. A pressure relief mechanism 3 is installed on the upper surface of the sealing cover 11. An anti-blocking mechanism 4 is installed on the side wall of the fermentation tank 1.
[0027] In this embodiment, the sealing cover 11 and sealing strip 14 can ensure the sealing of the inner cavity of the fermentation tank 1. Then, the temperature in the fermentation tank 1 can be controlled by the temperature sensor 15, circulation pipe 16 and stirring mechanism 2 to avoid the temperature in the fermentation tank 1 being affected by the external weather and causing a large temperature difference. Subsequently, the gas generated in the fermentation process in the fermentation tank 1 can be discharged by the pressure relief mechanism 3, and the yellow water in the fermentation tank 1 can be discharged by the anti-blocking mechanism 4.
[0028] In an optional embodiment, such as Figure 2As shown, the stirring mechanism 2 includes a first motor 21. The outer wall of the first motor 21 is fixedly connected to the upper surface of the sealing cover 11. The output end of the first motor 21 is fixedly connected to a rotating shaft 22 through the outer wall of the sealing cover 11. The rotating shaft 22 is located in the inner cavity of the fermentation tank 1. A heating rod 23 is fixedly connected to the inner wall of the rotating shaft 22. Heat-conducting rods 24 are evenly distributed on the outer wall of the rotating shaft 22. By starting the first motor 21, the rotating shaft 22 and the heat-conducting rods 24 are driven to rotate, thereby stirring the grain in the fermentation tank 1 and making the grain fermentation more thorough. During the stirring process, when it is necessary to raise the temperature in the fermentation tank 1, the heating rod 23 is activated to heat the rotating shaft 22 and the heat-conducting rods 24, thereby raising the temperature in the fermentation tank 1.
[0029] In an optional embodiment, such as Figure 2 and Figure 4 As shown, the pressure relief mechanism 3 includes a sealed box 31. The bottom end of the sealed box 31 is fixedly connected to the upper surface of the sealed cover 11. An air inlet pipe 33 is fixedly connected to the bottom end of the sealed box 31. The outer wall of the air inlet pipe 33 penetrates the outer wall of the sealed cover 11 and communicates with the inner cavity of the fermentation tank 1. A float 35 is slidably connected to the inner wall of the sealed box 31. A one-way valve 34 is fixedly connected to the inner cavity of the sealed box 31 near the air inlet pipe 33. A sealing plug 32 is provided on the inner wall of the sealed box 31 near the float 35. During fermentation, the generated gas enters the sealed box 31 through the air inlet pipe 33. When enough gas enters the sealed box 31, it pushes the float 35 to move upward. The position of the float 35 in the sealed box 31 can be observed through the scale on the outer wall of the sealed box 31. When the float 35 moves to a sufficient height, the sealing plug 32 can be opened to relieve pressure and discharge the gas in the sealed box 31. Under the action of the one-way valve 34, outside air cannot enter the fermentation tank 1.
[0030] In an optional embodiment, such as Figure 2 and Figure 4 As shown, the outer wall of the sealed box 31 has a scale, and the scale is transparent. The position of the float 35 inside the sealed box 31 can be observed through the scale so that pressure can be released when needed.
[0031] In an optional embodiment, such as Figure 2 and Figure 4 As shown, the connection between the air intake pipe 33 and the sealing cover 11 is sealed by a sealing ring to prevent air leakage.
[0032] In an optional embodiment, such as Figure 2 and Figure 5As shown, the anti-clogging mechanism 4 includes a drain pipe 41. A solenoid valve is installed in the inner cavity of the drain pipe 41 near the fermentation tank 1. A filter screen 42 is slidably connected to the inner wall of the drain pipe 41. A pull rod 43 is inserted into the inner wall of the filter screen 42. The outer wall of the pull rod 43 is slidably connected to the inner wall of the drain pipe 41. A spring 44 is movably sleeved on the outer wall of the pull rod 43. One end of the spring 44 is fixedly connected to the outer wall of the drain pipe 41, and the other end is fixedly connected to the outer wall of the pull rod 43. When the filter screen 42 needs to be replaced, the pull rod 43 is pulled to extend the spring 44, so that the outer wall of the pull rod 43 is no longer inserted into the inner wall of the filter screen 42. Then the pull rod can be pulled to remove the filter screen 42 from the inner cavity of the drain pipe 41 for replacement.
[0033] In an optional embodiment, such as Figure 2 and Figure 5 As shown, a protective box 45 is fixedly connected to the inner cavity of the drain pipe 41 via a fixing plate. A second motor 46 is rotatably connected to the inner wall of the protective box 45. The output shaft of the second motor 46 is rotatably connected to the inner wall of the drain pipe 41. A driving bevel gear 47 is fixedly connected to the outer wall of the second motor 46 located within the inner cavity of the protective box 45. A driven bevel gear 48 meshes with the outer wall of the driving bevel gear 47. A shaft is fixedly connected to the axis of the driven bevel gear 48. The outer wall of the shaft is rotatably connected to the inner wall of the protective box 45. A shaft is fixedly connected to the outer wall of the shaft. The scraper 49 has its outer wall in contact with the outer wall of the filter screen 42. When it is necessary to drain the yellow water in the fermentation tank 1, the solenoid valve in the drain pipe 41 is opened, allowing the yellow water in the fermentation tank 1 to be discharged through the drain pipe 41. During the discharge process, the filter screen 42 filters the water to prevent the grain in the fermentation tank 1 from being discharged. During the discharge process, the second motor 46 is started, which drives the active bevel gear 47 and the driven bevel gear 48 to mesh, driving the shaft and scraper 49 to rotate synchronously, thereby cleaning the outer wall of the filter screen 42 and preventing blockage.
[0034] In an optional embodiment, such as Figure 2 and Figure 5 As shown, a pull rod is fixedly connected to the outer wall of the filter screen 42. The filter screen 42 can be quickly pulled out or pushed in by the pull rod, making it convenient to replace or install it.
[0035] The above embodiment discloses a fermentation pit with temperature control. During the grain fermentation process in the fermentation pit 1, a temperature sensor 15 monitors the temperature in the fermentation pit 1 in real time. During fermentation, depending on the different fermentation stages, the system selects whether to stir the grain in the fermentation pit 1. The first motor 21 is activated, driving the rotating shaft 22 and the heat-conducting rod 24 to rotate, thereby stirring the grain in the fermentation pit 1 to ensure more thorough fermentation. During stirring, when it is necessary to raise the temperature in the fermentation pit 1, the heating rod 23 is activated to heat the rotating shaft 22 and the heat-conducting rod 24, thus raising the temperature in the fermentation pit 1. When it is necessary to lower the temperature, the liquid inlet 12 is connected to the output end of the water pump. The outlet 13 is connected to the inlet of the coolant tank. A water pump then pumps coolant from the inlet 12 to the circulation pipe 16, which then returns the coolant to the coolant tank. This circulation pipe 16 cools the fermentation tank 1. Through real-time monitoring by the temperature sensor 15, combined with the heating rod 23 and circulation pipe 16, the temperature in the fermentation tank 1 can be freely controlled, preventing large temperature differences from affecting the fermentation of the grains. During fermentation, the generated gas enters the sealed box 31 through the air inlet pipe 33. When enough gas enters the sealed box 31, it pushes the float 35 upwards. The float 35 can be observed through the scale on the outer wall of the sealed box 31. Inside the sealed box 31, when the float 35 moves to a sufficient height, the sealing plug 32 can be opened to release pressure and expel the gas from the sealed box 31. Under the action of the one-way valve 34, outside air cannot enter the fermentation tank 1. Subsequently, when it is necessary to drain the yellow water from the fermentation tank 1, the solenoid valve in the drain pipe 41 is opened, allowing the yellow water in the fermentation tank 1 to drain out through the drain pipe 41. During the draining process, the filter screen 42 filters the water, preventing the grain from being discharged from the fermentation tank 1. During the draining process, the second motor 46 is started, driving the active bevel gear 47 and the driven bevel gear 48 to mesh, causing the shaft and scraper 49 to rotate synchronously, thereby cleaning the outer wall of the filter screen 42 to prevent clogging. Afterwards, when it is necessary to... When replacing the filter screen 42, pull the lever 43 to extend the spring 44, so that the outer wall of the lever 43 is no longer inserted into the inner wall of the filter screen 42. Then, pull the pull rod to remove the filter screen 42 from the inner cavity of the drain pipe 41 for replacement. In summary, the sealing cover 11 and sealing strip 14 can ensure the sealing of the inner cavity of the fermentation tank 1. Then, the temperature sensor 15, circulation pipe 16 and stirring mechanism 2 can control the temperature in the fermentation tank 1 to avoid the temperature in the fermentation tank 1 being affected by the external weather and causing a large temperature difference. Subsequently, the pressure relief mechanism 3 can release the gas generated in the fermentation tank 1 during fermentation, and the anti-blocking mechanism 4 can drain the yellow water in the fermentation tank 1.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
