Description
Technical Field
[0001] This utility model relates to the field of astragalus black tea production technology, specifically a fermentation device for astragalus black tea production with a turning mechanism. Background Technology
[0002] Astragalus black tea is a tea beverage that combines astragalus and black tea. The production process of astragalus black tea is relatively simple. Usually, astragalus and black tea are mixed in a certain proportion and then fermented, which requires the use of fermentation equipment.
[0003] Existing fermentation equipment is usually simple in structure. As tea leaves tend to pile up during fermentation, the tea leaves are easily heated unevenly, which also reduces the mixing and oxygen exchange between the tea leaves and the fermented tea.
[0004] To overcome the aforementioned defects, existing technology (Chinese patent application number: 202323076066.2, application date: November 14, 2023) discloses a novel uniform stirring device for black tea fermentation. This novel uniform stirring device uses a servo motor to drive a transmission belt to rotate. The transmission belt, through a driven wheel, drives a flipping rod to flip the black tea and black tea liquid. This flipping mechanism allows the bottom black tea and black tea liquid to be flipped, preventing the upper black tea from failing to fully absorb the black tea liquid, thus preventing a decline in black tea quality. One end of the inlet pipe is secured with a sealing ring via a ring-shaped locking block. Rotating the hollow rod and pulling the I-shaped rod through the opening causes a spring to return, causing one end of the I-shaped rod to engage with one side of the inlet pipe. This allows users to quickly disassemble and assemble the inlet pipe and delivery pipe using a quick-release mechanism to clean any residual black tea liquid inside, improving work efficiency.
[0005] While existing technologies can solve the problem of stirring black tea and black tea liquor, the rigid structure of the rotating blades can easily cause physical damage to the black tea leaves, such as breakage and tearing. This damage not only reduces the integrity of the black tea but may also affect the fermentation effect and final quality. Furthermore, black tea and black tea liquor are prone to remain or adhere to the inner wall of the device, and it is impossible to effectively scrape off the remaining or adhered black tea and black tea liquor, which can easily lead to uneven fermentation or contamination, thereby further reducing the utilization rate and fermentation efficiency of the black tea.
[0006] Therefore, we proposed that a fermentation device for producing Astragalus black tea with a turning mechanism can effectively solve the above problems. Utility Model Content
[0007] The purpose of this invention is to provide a fermentation device for producing Astragalus black tea with a turning mechanism, in order to solve the problem that the rigid structure of the turning rods in the current novel uniform stirring devices mentioned in the background art can easily cause physical damage to the black tea leaves, such as breakage and tearing. This damage not only reduces the integrity of the black tea, but may also affect the fermentation effect and final quality of the black tea. Furthermore, black tea and black tea liquor are easily left or adhered to the inner wall of the device, and it is impossible to effectively scrape off the leftover or adhered black tea and black tea liquor, which can easily cause uneven fermentation or contamination, thereby further reducing the utilization rate and fermentation efficiency of the black tea.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0033] Please see Figures 1-7 The present invention provides the following technical solution:
[0034] Example 1: To address the issue that the rigid structure of the rotating blades in modern uniform stirring devices can easily cause physical damage to black tea leaves, such as breakage and tearing, this damage not only reduces the integrity of the black tea but may also affect the fermentation effect and final quality. Furthermore, black tea and tea liquor tend to remain or adhere to the inner wall of the device, making it difficult to effectively scrape off the residue, which can lead to uneven fermentation or contamination, further reducing the utilization rate and fermentation efficiency of the black tea. (See attached...) Figure 1 and attached Figure 4 The system includes a base 1, with support plates 2 fixedly installed on the top of the front and rear sides of the base 1. A groove 13 is formed inside the support plate 2, and a sliding rod 17 is movably connected to the inner wall of the groove 13. A rotating seat 3 is fixedly connected to the top of the sliding rod 17, and a fermentation tank 4 is installed on the inner top of the rotating seat 3. A feed pipe 5 is fixedly connected to the top of the left side of the fermentation tank 4, and a discharge pipe 6 is fixedly connected to the bottom of the left side of the fermentation tank 4. A guide plate 23 is fixedly installed on the inner bottom wall of the discharge pipe 6, and a servo motor body 7 is installed on the top of the discharge pipe 6. A stirring rod 8 is fixedly installed on the output shaft of the servo motor body 7 via a coupling. Stirring blades 9 are symmetrically fixedly installed on the outer wall of the stirring rod 8, and connecting rods 10 are symmetrically fixedly installed on the outer wall of the stirring rod 8. A scraper 11 is fixedly installed at the outer end of the connecting rod 10. The stirring rod 8 and the stirring blades 9 are tightly fitted together, and the stirring blades 9 are made of silicone.
[0035] The astragalus black tea to be fermented is manually added to the fermentation tank 4 through the feed pipe 5 by the staff. After an appropriate amount of astragalus black tea is added to the fermentation tank 4, when it is necessary to agitate the astragalus black tea in the fermentation tank 4, the staff starts the servo motor body 7 through the external control board. The output shaft of the servo motor body 7 drives the stirring rod 8 to rotate in the fermentation tank 4, causing the stirring rod 8 to drive the two stirring blades 9 to rotate. The stirring blades 9 agitate the astragalus black tea in the fermentation tank 4, promoting mixing and oxygen exchange, which is beneficial to the fermentation process. 9 is made of silicone, which is soft, heat-resistant, and corrosion-resistant, and will not damage the astragalus black tea. At the same time, as the stirring rod 8 rotates, it drives the scrapers 11 connected to each connecting rod 10 to rotate. The design of the scrapers 11 can closely fit the inner wall of the fermentation tank 4, thereby effectively scraping off the astragalus black tea residue or adhering to the inner wall, preventing the accumulation of black tea on the inner wall of the fermentation tank 4, avoiding uneven fermentation or contamination, improving the utilization rate and fermentation efficiency of black tea, thus achieving effective turning and scraping of astragalus black tea, ensuring the smooth progress of the fermentation process and the full utilization of black tea.
[0036] Example 2: The astragalus and black tea can be further mixed and stirred, as shown in the attached document. Figure 1 -Attached Figure 3 and attached Figure 5 -Attached Figure 7 A baffle 12 is fixedly installed on the front of the support plate 2. An arc-shaped seat 14 is fixedly installed on the back of the support plate 2, located on top of the base 1. A worm gear 15 is fixedly installed on the outer wall of the arc-shaped seat 14. Grooves 16 are formed inside the front and rear sides of the rotating seat 3, and the grooves 16 are fitted onto the outer wall of the support plate 2. A rotating motor body 18 is provided on the left side of the rotating seat 3. A worm gear 19 is fixedly installed on the output shaft of the rotating motor body 18 through a coupling. A support cylinder 21 is rotatably connected to the top right side of the base 1. An extension rod 20 is movably connected inside the support cylinder 21. A fixed ring plate is rotatably connected to the top of the extension rod 20, and the fixed ring plate is fixedly connected to the fermentation tank 4. A spring 22 is fixedly installed on the top of the extension rod 20. The worm gear 15 and the worm gear 19 are meshed, and the worm gear 15 is set as a semi-circular arc structure. The worm gear 15 is fixedly connected to the arc-shaped seat 14. The groove 16 is rotatably connected to the support plate 2, and the groove 16 is integrated with the rotating seat 3. The rotating seat 3 is tightly fitted with the slide rod 17, and the slide rod 17 is slidably connected to the slide groove 13.
[0037] While the astragalus black tea in fermentation tank 4 is being agitated by the stirring blade 9, the operator starts the rotating motor body 18 via an external control panel. The output shaft of the rotating motor body 18 drives the worm gear 19 to rotate counterclockwise or clockwise. The worm gear 19 meshes with the worm wheel 15, causing it to rotate. Simultaneously, this rotation drives the rotating seat 3 to rotate left and right on the support plate 2 via the groove 16. As the rotating seat 3 rotates, the sliding rod 17 slides within the corresponding groove 13, increasing the stability and guidance of the rotating seat 3. This causes the rotating seat 3 to slide along a predetermined trajectory, thereby rotating the installed fermentation tank 4. During the rotation of the fermentation tank 4, the extension rod 20 connected to the fixed ring plate moves within the support cylinder 21. At the same time, the extension rod 20 stretches the spring 22, increasing the stability of the rotation of the fermentation tank 4 and preventing the fermentation tank 4 from shaking or tilting due to inertia or external force during the rotation. This ensures the smoothness and safety of the rotation, allowing the fermentation tank 4 to further mix and turn the astragalus black tea, thereby further improving the uniformity and efficiency of fermentation.
