Description

Technical Field

[0001] This utility model relates to the field of liquor production technology, and in particular to a liquor brewing and fermentation tank. Background Technology

[0002] Maotai-flavor liquor originates from China's traditional brewing culture, especially represented by Maotai liquor from Guizhou Province. The brewing of Maotai-flavor liquor requires multiple processes. After the raw materials are processed and yeast is added, the raw materials need to be piled up and sealed to allow them to ferment.

[0003] A search revealed Chinese patent publication number CN219079428U, which discloses a fermentation tank for brewing Maotai-flavor liquor, relating to the field of Maotai-flavor liquor brewing technology. The tank includes a fermentation tank body, with a silicone pad abutting against the top of the fermentation tank body. A cover plate is fixedly connected to the top of the silicone pad, and a fixing block is fixedly connected to the bottom of the cover plate. A silicone sleeve is fitted around the outside of the fixing block. First nut blocks are fixedly connected to both sides of the fermentation tank body, with a fixing bolt threaded to the top of each first nut block, and a second nut block penetrating through the top of each fixing bolt.

[0004] However, in actual use, it was found that the temperature of the raw materials inside the fermentation tank could not be monitored in real time. If the temperature was too high, the yeast activity would be too strong, resulting in unpleasant flavors and aromas; while if the temperature was too low, the yeast activity would be inhibited, resulting in insufficient fermentation and affecting the taste of the liquor. Furthermore, during the fermentation process, excessive carbon dioxide would affect the characteristics of the liquor, such as causing microbubbles to rise, affecting the appearance and taste. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the existing technology of not being able to monitor the temperature of the raw materials inside the fermentation tank in real time and that excessive carbon dioxide will affect the taste of the liquor, and to propose a fermentation tank for brewing baijiu.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fermentation tank for brewing baijiu (Chinese liquor) includes a tank body and a sealing cover detachably connected to the opening of the tank body via a sealing assembly. The sealing cover is equipped with a gas detection sensor, and the detection end of the gas detection sensor extends to the bottom of the sealing cover. A measuring rod is fixedly connected to the inner wall of the tank body via a mounting rod. The measuring rod is equipped with a temperature sensor. A detection recorder is installed on the outer wall of the tank body, and the temperature sensor is electrically connected to the detection recorder.

[0008] To facilitate the sealing connection between the sealing cap and the tank, preferably, the sealing assembly includes a sealing gasket, a groove is provided on the inner wall of the tank, the sealing gasket is fixedly connected to the bottom of the sealing cap, and the sealing gasket cooperates with the groove.

[0009] To improve the sealing effect of the sealing cap, a first limiting block is fixedly connected to the outer wall of the sealing cap, and a second limiting block is fixedly connected to the outer wall of the tank body, and the two sets of limiting blocks are connected by locking bolts.

[0010] To facilitate the release of excess gas inside the tank, preferably, a vent pipe is fixedly connected to the sealing cover, and a pressure relief valve is provided on the vent pipe.

[0011] To facilitate temperature detection at different heights inside the tank, preferably, multiple sets of temperature sensors are provided, and these multiple sets of temperature sensors are equidistantly arranged on the measuring rod.

[0012] To facilitate support of the tank, preferably, the outer wall of the tank is fixedly connected with support legs.

[0013] Compared with the prior art, this utility model provides a fermentation tank for brewing baijiu (Chinese liquor), which has the following beneficial effects:

[0014] 1. This liquor brewing fermentation tank can monitor carbon dioxide concentration to better understand the progress of the fermentation process inside the tank and adjust relevant parameters in a timely manner. If the carbon dioxide concentration exceeds the safety threshold, the sensor can trigger an alarm to remind the user to take measures to release the pressure properly using the pressure relief valve, thereby preventing safety hazards caused by gas accumulation.

[0015] 2. This baijiu brewing fermentation tank uses multiple sets of temperature sensors arranged at certain intervals to measure temperature changes at different heights or in different areas, obtaining more comprehensive data. It monitors the temperature at different depths and in different areas of the fermentation liquid, thereby monitoring changes in the fermentation environment in real time. The temperature sensors are then connected to a detection recorder to record temperature data in real time, allowing for easy viewing of historical data and analysis of temperature change trends, thus enabling adjustments to the fermentation strategy.

[0016] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This invention can better understand the progress of the fermentation process in the tank and adjust relevant parameters in a timely manner. If the concentration of carbon dioxide exceeds the safety threshold, a pressure relief valve can be used to release the pressure reasonably, thereby preventing safety hazards caused by gas accumulation and improving the fermentation taste of baijiu. At the same time, it can also monitor the temperature of different depths and areas of the fermentation liquid, thereby monitoring changes in the fermentation environment in real time.

[0024] Example:

[0025] Reference Figures 1-4 A fermentation tank for brewing baijiu (Chinese liquor) includes a tank body 1 with an opening for feeding processed raw materials into the tank body 1 for stacking. A sealing cap 2 can be detachably connected to the opening of the tank body 1 via a sealing assembly. Support legs are fixedly connected to the outer wall of the tank body 1 for supporting the tank body 1.

[0026] To improve the sealing effect between the sealing cap 2 and the opening of the tank body 1, the sealing assembly includes a sealing gasket 10. A groove 9 is provided on the inner wall of the tank body 1. The sealing gasket 10 is fixedly connected to the bottom of the sealing cap 2, and the sealing gasket 10 cooperates with the groove 9. The cross-sectional area of ​​the groove 9 is smaller than the cross-sectional area of ​​the sealing gasket 10. Both are semi-circular, and the material of the sealing gasket 10 is silicone. The sealing gasket 10 can be pressed into the groove 9 to achieve a sealing effect.

[0027] An opening is provided on the tank body 1 to facilitate the input of processed raw materials, and a sealing cap 2 is used to achieve a seal. The sealing assembly consists of a sealing gasket 10 and a groove 9. The sealing gasket 10 is made of silicone material, which has good elasticity and sealing performance. The cross-sectional area of ​​the groove 9 is smaller than that of the sealing gasket 10, ensuring a stable sealing effect after being pressed into the groove 9, preventing gas and impurities from entering.

[0028] The first limiting block 3 is fixed on the outer wall of the sealing cover 2. Its main function is to ensure that the sealing cover 2 remains in place when closed and to prevent it from loosening due to vibration or external force. The second limiting block 4 is fixed on the outer wall of the tank body 1 and cooperates with the first limiting block 3. They are connected to each other by locking bolts 5, which can enhance the airtightness between the sealing cover 2 and the tank body 1.

[0029] It should be explained that, in addition to locking bolt 5, self-locking bolts or locking devices can also be used to maintain a locked state under high pressure, reduce the risk of loosening due to temperature changes, and make installation or disassembly more convenient.

[0030] In addition, a gas detection sensor 8 is provided on the sealing cap 2, and the detection end of the gas detection sensor 8 extends to the bottom of the sealing cap 2. The gas detection sensor 8 is a carbon dioxide detection sensor. The detection end of the sensor extends directly to the bottom of the sealing cap 2, which can effectively capture gas changes in the sealed container and monitor the fermentation status in real time.

[0031] This sensor is specifically designed to monitor the concentration of carbon dioxide produced during fermentation. The production of carbon dioxide is a hallmark of yeast fermentation, so monitoring its concentration is crucial for controlling the fermentation process and ensuring the quality of baijiu products.

[0032] A gas outlet pipe 6 is fixedly connected to the sealing cover 2, and a pressure relief valve 7 is installed on the gas outlet pipe 6. By monitoring the carbon dioxide concentration, the progress of the fermentation process in the tank 1 can be better understood, and relevant parameters can be adjusted in a timely manner. If the carbon dioxide concentration exceeds the safety threshold, the sensor can trigger an alarm to remind the user to take measures to release the pressure reasonably using the pressure relief valve 7, thereby preventing safety hazards caused by gas accumulation.

[0033] A measuring rod 11 is also provided inside the tank body 1 and is fixedly connected to the inner wall of the tank body 1 by a mounting rod. A temperature sensor 12 is provided on the measuring rod 11, and a detection recorder 13 is provided on the outer wall of the tank body 1. The temperature sensor 12 is electrically connected to the detection recorder 13, and multiple sets of temperature sensors 12 are provided, and the multiple sets of temperature sensors 12 are equidistantly arranged on the measuring rod 11.

[0034] The measuring rod 11 is fixed to the inner wall of the tank 1 by the mounting rod, which provides a solid support, allowing the temperature sensor 12 to make effective measurements in the appropriate position. The presence of the measuring rod 11 also allows multiple sets of temperature sensors 12 to be arranged at a certain spacing. Seven sets are used in this device for reference only, so as to measure temperature changes at different heights or in different areas, obtain more comprehensive data, monitor the temperature at different depths and in different areas of the fermentation liquid, and thus monitor changes in the fermentation environment in real time. The temperature sensor 12 is then connected to the detection recorder 13 to record temperature data in real time, so that historical data can be easily viewed, temperature change trends can be analyzed, and fermentation strategies can be adjusted accordingly.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
