Description

Technical Field

[0001] This utility model patent belongs to the field of brewing equipment technology, specifically relating to a fermentation tank for stirring, temperature control, and liquid level measurement in brewing. Background Technology

[0002] The brewing process of wine is divided into two main parts: fermentation and distillation. Fermented winemaking refers to the fermentation of grains by microorganisms under aerobic or anaerobic conditions. It has a long history in my country. More than 5,000 years ago, the Chinese people developed a splendid winemaking culture. In the winemaking industry, raw materials need to be placed in fermentation containers and kept at a certain temperature for a long time so that the microorganisms in the raw materials can ferment rapidly. Fermentation tanks are equipment used for the fermentation process. They can provide precise control parameters, such as temperature, humidity, and oxygen supply. These conditions are crucial for the growth and metabolic activities of yeast or other microorganisms.

[0003] Existing fermentation tanks, such as the brewing fermentation tank disclosed in Chinese Patent (CN220685046U), include: a tank body for holding and fermenting raw materials; a temperature control and protection component located outside the tank body for controlling the temperature of the fermenting raw materials inside the tank and protecting the tank body during the fermentation process; and a stirring component located inside the tank for stirring and mixing the raw materials. Although this device can perform multi-angle stirring, it still has the following drawbacks in practical use:

[0004] 1. In industrial production, the fermentation tanks used for brewing are quite large, and can hold several tons of raw materials for fermentation at the same time. Stirring at multiple angles will increase the torque and wear on the drive shaft and drive motor, shortening their service life. If stirring is only done in the vertical direction, the wine will be affected by the force and rotate with the stirring rod, forming a vortex and causing a swirling phenomenon, which makes the mixing effect of the raw materials poor. At the same time, it is impossible to expel the fermentation gas in the fermentation material upwards, and it is also impossible to avoid the phenomenon of tank expansion.

[0005] 2. At the same time, the commonly used temperature monitoring devices are set at the bottom or top of the tank, but the huge tank body cannot guarantee the accuracy of the temperature measurement. In addition, the liquid level monitoring devices currently used will also cause monitoring errors due to the pressure deviation at different positions in the large fermentation tank.

[0006] 3. Currently, heat dissipation and temperature control of the tank are usually achieved through the tank itself and an independent temperature control device on each tank. However, the heat dissipation effect of the tank itself is not good. Moreover, during brewing, the factory usually contains multiple sets of fermentation tanks. If a temperature control device is installed on each set of tanks, it will undoubtedly greatly increase the investment in equipment and the cost of manual management.

[0007] To address the aforementioned issues, this paper proposes a fermentation tank for stirring, temperature control, and liquid level measurement in brewing. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. Example 1

[0034] like Figures 1 to 9 As shown, the existing technology in this embodiment has the following problems: The inventors found that in industrial production, the fermentation tanks used for brewing are quite large. Multi-angle stirring will increase the torque and wear on the drive shaft and drive motor, shortening their service life. If stirring is only done vertically, the wine will be affected by the force and rotate with the stirring rod, forming a vortex and causing a swirling phenomenon, resulting in poor mixing of raw materials. At the same time, it is impossible to expel the fermentation gas in the fermentation material upwards, and it is also impossible to avoid the phenomenon of tank expansion. Meanwhile, the temperature monitoring devices currently used are set at the bottom or top of the tank, but the huge tank body cannot guarantee the accuracy of the temperature measurement. Moreover, the liquid level monitoring devices currently used will also cause monitoring errors due to the pressure deviation at different positions in the large fermentation tank. Currently, the heat dissipation and temperature control of the tank are usually achieved through the tank itself and an independent temperature control device on each tank. However, the heat dissipation effect of the tank itself is not good. In addition, during brewing, the factory usually contains multiple sets of fermentation tanks. If a temperature control device is set on each set of tanks, it will undoubtedly greatly increase the investment in equipment and the labor management cost.

[0035] Therefore, the inventor provides a fermentation tank for stirring, temperature control, and liquid level measurement in brewing, including a tank body 1 and a base 2. The base 2 is installed at the bottom of the tank body 1, and a control cabinet 3 is installed at the front of the base 2. The tank body 1 is equipped with a stirring mechanism to prevent the liquid from forming a vortex and causing swirling during stirring. The upper left side of the tank body 1 is equipped with a liquid level detection device that can simultaneously monitor the pressure at different positions inside the large fermentation tank and a temperature detection device that can penetrate deep into the tank body 1 for detection. The outer wall of the tank body 1 is equipped with a Miller plate 4 that can dissipate heat based on the room temperature.

[0036] The control cabinet 3 is equipped with a processor 5, a display 6, control buttons 7, a power interface 8, and an audible and visual alarm 9. The processor 5 is electrically connected to the display 6, control buttons 7, power interface 8, audible and visual alarm 9, stirring mechanism, liquid level detection device, and temperature detection device. The power interface 8 provides power to the processor 5, display 6, control buttons 7, audible and visual alarm 9, stirring mechanism, liquid level detection device, and temperature detection device by connecting to a power source.

[0037] The Miller plate 4 in this structure allows the interior of the tank 1 to exchange heat with the factory through several semi-circular heat dissipation holes on its surface, thereby dissipating heat from the interior of the tank 1. In this way, the fermentation temperature inside the tank 1 can be controlled by adjusting the room temperature in the factory according to the heat dissipation efficiency of the Miller plate 4.

[0038] Its effects are as follows: By setting two sets of reversible stirring mechanisms in the tank 1, the device avoids the formation of vortices and swirling phenomena in the liquid during stirring, thereby improving stirring efficiency, making the mixing effect of fermentation materials better, and allowing fermentation gases in the fermentation materials to be discharged upwards more effectively, avoiding tank bloating; The liquid level monitoring device set on the outside of the tank 1 can balance the hydraulic pressure in the liquid level detection pipe 28 outside the tank with that inside the tank through hydraulic balance pipes 30 set at different heights, thereby ensuring that the liquid level in the liquid level detection pipe 28 is the same as that inside the tank, thus ensuring the accuracy of the detection value; The temperature monitoring device allows users to easily insert the temperature probe 33 into the tank 1 from different heights to measure the temperature, thereby facilitating the monitoring of the temperature of the fermentation materials inside the tank 1.

[0039] Furthermore, a feed inlet 10 is installed at the top of the tank body 1, a pressure detection device 11 is installed on the side of the feed inlet 10 on the tank body 1, and a slag discharge port 12 is installed on the top and bottom sides of the tank body 1.

[0040] Furthermore, the stirring mechanism also includes a drive motor 13, a stirring spindle 14, spiral blades 15, a positioning base 16, a platform 17, a small sun gear 18, planetary gears 19, a bracket 20, a large sun gear 21, a limiting structure, and a scraping structure. The drive motor 13 is installed at the bottom of the tank 1. The stirring spindle 14 is installed on the drive end of the drive motor 13. The spiral blades 15 are installed on the stirring spindle 14. The top end of the stirring spindle 14 is rotatably installed at the lower end of the positioning base 16, and the positioning base 16 is installed at the top inner side of the tank 1. A platform 17 is provided on the stirring spindle 14 below the positioning base 16. An installation groove 22 is provided between the base 16 and the base 17. A small sun gear 18 concentric with the stirring shaft 14 is provided on the base 17 below the installation groove 22. Three sets of planetary gears 19 are evenly rotatably installed on the lower surface of the positioning base 16 above the installation groove 22, and the inner side of the planetary gears 19 is meshed with the small sun gears 18. A bracket 20 is installed in the installation groove 22 outside the planetary gears 19, and the bracket 20 is meshed with the planetary gears 19 through the large sun gear 21 on its inner side. The outer side of the bracket 20 is rotatably connected to the inner wall of the tank 1 through a limiting mechanism. A scraping and stirring structure that is close to the inner wall of the tank 1 is provided at the bottom of the bracket 20.

[0041] This structure can provide power to the stirring shaft 14 via the drive motor 13, thereby driving the spiral blades 15 to stir inside the tank 1. At the same time, the small sun wheel 18 at the top of the stirring shaft 14 will transmit power to the planetary wheel 19 and change its direction of motion. The planetary wheel 19 will transmit power to the large sun wheel 21 inside the support 20 without changing the direction of motion of the large sun wheel 21. In this way, the rotation direction of the support 20 will be opposite to that of the stirring shaft 14. This will scrape off the material adhering to the inner wall of the tank 1 and form a force on the fermentation material opposite to that of the stirring shaft 14, thereby avoiding the overall swirling of the material caused by the formation of vortices and making the raw materials more thoroughly mixed.

[0042] Furthermore, the limiting structure also includes a limiting card 23 and a limiting groove 24. The limiting card 23 is set on the inner wall of the tank body 1, and the limiting groove 24 is set on the outer side of the bracket 20.

[0043] This structure, together with the mounting slot 22, allows the bracket 20 to rotate more stably within the tank 1.

[0044] Furthermore, the scraping and stirring structure also includes a stirring column 25, a scraper strip 26, and a stirring support rod 27. The stirring column 25 is installed at the lower end of the outer side of the support 20. The scraper strip 26 with a triangular end face is installed on the outer side of the stirring column 25 close to the inner wall of the tank 1. The stirring support rod 27 is connected to the inner side of the stirring column 25, and the inner end of the stirring support rod 27 is rotatably installed on the stirring main shaft 14.

[0045] The stirring column 25 and stirring support rod 27 in this structure can drive the fermentation material to be stirred in the opposite direction to the stirring main shaft 14. At the same time, the stirring support rod 27 can also provide support for the stirring column 25, while the scraper strip 26 can scrape off the material adhering to the inner wall of the tank 1, preventing the material from being squeezed and deformed when the stirring column 25 rotates.

[0046] Furthermore, the liquid level detection device also includes a liquid level detection tube 28, a liquid level sensor 29, and a hydraulic balance tube 30. The liquid level detection tube 28 is installed on the outside of the tank body 1 and its top and bottom ends are connected to the inside of the tank body 1. The liquid level sensor 29 is installed on the top of the liquid level detection tube 28. The liquid level detection tube 28 is connected to the tank body 1 from top to bottom through several hydraulic balance tubes 30.

[0047] This structure uses hydraulic balance pipes 30 set at different heights to balance the hydraulic pressure in the liquid level detection pipe 28 outside the tank with that inside the tank, thereby ensuring that the liquid level in the liquid level detection pipe 28 is the same as that inside the tank, thus ensuring the accuracy of the detection value.

[0048] Furthermore, a sample collection port 31 is provided at the bottom of the liquid level detection tube 28; this structure allows users to conveniently collect and observe the fermentation material inside the tank 1.

[0049] Furthermore, the temperature detection device also includes a temperature measuring port 32 and a temperature measuring probe 33. The temperature measuring port 32 is set on the outside of the liquid level detection pipe 28, which is parallel to the hydraulic balance pipe 30. The temperature measuring probe 33 is installed in the temperature measuring port 32 and its front end can pass through the hydraulic balance pipe 30 and enter the tank 1.

[0050] This structure allows users to easily insert the temperature probe 33 into the tank 1 at different heights to measure the temperature, thus facilitating the monitoring of the temperature of the fermentation material inside the tank 1.

[0051] Furthermore, the temperature measuring port 32 is provided with a sealing plug 34 and a locking screw 35. The sealing plug 34 is placed in the pipe opening outside the liquid level detection tube 28, and the locking screw 35 is installed on the outside of the pipe opening.

[0052] During temperature measurement, the locking sleeve 35 can be loosened to allow the sterilized temperature probe 33 to extend into and out of the tank 1. During this process, the temperature probe 33 is tightly wrapped by the sealing plug 34 to prevent leakage. Under normal conditions, the locking sleeve 35 can be tightened.

[0053] The working principle of this utility model is as follows:

[0054] The device incorporates two sets of counter-rotating stirring mechanisms within the tank 1 to prevent vortex formation and swirling of the liquid during stirring, thereby improving stirring efficiency, enhancing the mixing effect of the fermentation materials, and facilitating the upward discharge of fermentation gases, thus preventing tank bloating. A liquid level monitoring device located on the outside of the tank 1 uses hydraulic balancing pipes 30 positioned at different heights to balance the hydraulic pressure within the external liquid level detection pipe 28 with that inside the tank, ensuring the liquid level in the detection pipe 28 matches that inside the tank and guaranteeing accurate readings. A temperature monitoring device allows users to easily insert a handheld temperature probe 33 into the tank 1 at different heights to measure the temperature of the fermentation materials within the tank 1.
