Description

Technical Field

[0001] This application belongs to the field of tea processing technology, specifically a device for the fermentation of dark tea. Background Technology

[0002] Dark tea is a special type of tea in China, rich in various essential nutrients. It has a sweet and mellow taste unlike green tea and is popular for its thirst-quenching, weight-loss, and digestive benefits, making it a highly sought-after health supplement. The production process of dark tea typically involves pile fermentation. During this process, the tea leaves are turned over appropriately to ensure even mixing between the central and peripheral areas, resulting in more thorough and uniform fermentation.

[0003] For example, patent CN210054487U discloses a turning device for the fermentation of dark tea, including turning claws, spiral plates, a circular roller, and connecting shafts. The circular roller has a connecting shaft on each of its left and right sides. Left-handed and right-handed spiral plates are connected to the left and right sides of the outer surface of the circular roller, respectively. Turning claws with equal axial distances are connected to the spiral lines of the spiral plates, and the turning claws are located on the outer surface of the circular roller. The advantages are twofold: firstly, the flexibility of the rubber sheet on the turning claw's turning surface and the elastic deformation of its outer edge make turning the tea leaves gentler, helping to avoid damage and ensuring the quality of the tea; secondly, the turning device not only performs the required turning operation but also automatically forms a pile shape similar to the original fermentation pile after the turning process, eliminating the need for manual re-piling, saving labor and facilitating subsequent fermentation.

[0004] However, the pile-turning device for the fermentation of dark tea described in this application is difficult to control and detect internal gas data during the fermentation process, and may not be able to maintain the optimal production environment during fermentation. Utility Model Content

[0005] The purpose of this application is to provide a black tea pile fermentation device to solve the problem that the aforementioned pile-turning device for black tea fermentation is difficult to control and detect internal gas data during the fermentation process, and may not be able to maintain the optimal production environment during fermentation.

[0006] The technical solution adopted in this application is as follows: A black tea pile fermentation device includes a fermentation cylinder, a limiting ring rotatably connected to the surface of the fermentation cylinder, a support rod fixedly connected to the lower end of the limiting ring, a base fixedly connected to the bottom end of the support rod, a rear baffle rotatably connected inside the fermentation cylinder, a rotating shaft fixedly connected to the top end of the rear baffle, a venting pipe fixedly connected inside the rotating shaft, a filter screen provided on the surface of the rotating shaft near the rear baffle, multiple stirring blades fixedly connected to the surface of the rotating shaft, a front baffle rotatably connected to the surface of the rotating shaft at the front end of the stirring blades, a threaded groove provided at the front end of the interior of the fermentation cylinder, and a gas detection platform installed at the top of the front end of the venting pipe.

[0007] By adopting the above technical solution, during use, the hydraulic rod on the surface of the fermentation cylinder can drive the slide block to slide to the rear end, thereby driving the rotating shaft inside the slide block to move to the rear end of the fermentation cylinder. When the front baffle on the surface of the rotating shaft moves to the threaded groove, the front baffle can be held and installed inside the front end of the fermentation cylinder. Then, the feeding plate is opened to add black tea raw materials into the fermentation cylinder. The space between the rear baffle and the front baffle is used to place the black tea raw materials. During the fermentation process, the raw materials can be turned over using a stirring device. The gas generated during the production process can flow through the filter screen to the air inlet groove inside the rotating shaft. When it is necessary to detect the gas inside the fermentation cylinder, the gas in the air inlet groove can be extracted and analyzed using a gas detection platform and a vent pipe to understand the fermentation environment data inside the fermentation cylinder.

[0008] In a preferred embodiment, a slide block is rotatably connected to the front end surface of the rotating shaft, a sliding groove is provided at the front end of the base, a slide rod is fixedly connected inside the sliding groove, and a slide block is slidably connected to the surface of the slide rod.

[0009] By adopting the above technical solution, when the slide block slides inside the slide groove, it can drive the rotating shaft to move back and forth together, and the slide rod can improve the stability of the slide block when it moves.

[0010] In a preferred embodiment, a hydraulic rod is mounted on the surface of the base, and a slide is fixedly connected to the top end of the hydraulic rod.

[0013] By adopting the above technical solution, the first motor is started, and the first motor gear is driven to rotate through the motor shaft, which in turn drives the cylindrical gear and the fermentation tank to rotate.

[0014] In a preferred embodiment, a rotating shaft gear is fixedly connected to the surface of the rotating shaft and to the front end of the front baffle, and a second motor gear is meshed at the lower end of the rotating shaft gear.

[0019] By adopting the above technical solution, before fermentation, the sample container can be opened, and the sample black tea raw material can be added inside. The filter baffle can block the raw material in the sample container from entering the air inlet.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0023] In this application, during fermentation, a stirring device can be used to agitate the raw materials. Gases generated during production can flow through a filter to the internal air inlet of the rotating shaft. When gas detection is needed within the fermentation chamber, a gas detection platform and venting pipe can be used to extract and analyze the gas from the air inlet, thus providing data on the fermentation environment. Before fermentation, the sample container can be opened, and sample black tea raw materials can be added. A filter baffle prevents the raw materials from entering the air inlet.

[0030] Example:

[0031] Reference Figure 1-4 The fermentation cylinder includes a fermentation tank 1. A limiting ring 3 is rotatably connected to the surface of the fermentation tank 1. A support rod 4 is fixedly connected to the lower end of the limiting ring 3, and a base 5 is fixedly connected to the bottom end of the support rod 4. A rear baffle 21 is rotatably connected inside the fermentation tank 1. A rotating shaft 10 is fixedly connected to the top of the rear baffle 21. A vent pipe 12 is fixedly connected inside the rotating shaft 10. A filter screen 20 is provided on the surface of the rotating shaft 10 near the rear baffle 21. Multiple stirring blades 23 are fixedly connected to the surface of the rotating shaft 10. A front baffle 24 is rotatably connected to the surface of the rotating shaft 10 at the front end of the stirring blades 23. A threaded groove 16 is provided at the front end of the interior of the fermentation tank 1. A gas detection platform 13 is installed at the top of the front end of the vent pipe 12. The limiting ring 3 and the support rod 4 support the fermentation tank 1, allowing it to rotate within the limiting ring 3. The rotating shaft 10 inside the fermentation tank 1 can stir the black tea inside through the stirring blades 23. The rotation direction of the rotating shaft 10 is opposite to that of the fermentation tank 1, which improves the stirring effect. The threaded groove 16 at the front end of the fermentation cylinder 1 can be used to thread a front baffle 24. The front baffle 24 is located on the surface of the rotating shaft 10 and can rotate. The rotating shaft 10 can slide back and forth inside the fermentation cylinder 1, thereby driving the front baffle 24, stirring blade 23, and rear baffle 21 on the surface of the rotating shaft 10 to move into the fermentation cylinder 1. In use, the hydraulic rod 6 on the surface of the fermentation cylinder 1 can be used to drive the slide 7 to slide to the rear end, thereby driving the rotating shaft 10 inside the slide 7 to move to the rear end of the fermentation cylinder 1. When the front baffle 24 on the surface of the rotating shaft 10 moves to the threaded groove 16, the front baffle 24 can be held and rotated to install the front baffle 24 into the front end of the fermentation cylinder 1. Then, the feeding plate 17 is opened to add black tea raw materials into the fermentation cylinder 1. The space between the rear baffle 21 and the front baffle 24 is used to place the black tea raw materials. During the fermentation process, the raw materials can be turned over using a stirring device. The gas generated during the production process can flow through the filter screen 20 to the internal air inlet slot 28 of the rotating shaft 10. When it is necessary to detect the gas in the fermentation tank 1, the gas in the air inlet slot 28 can be extracted and analyzed using the gas detection platform 13 and the vent pipe 12 to understand the fermentation environment data in the fermentation tank 1.

A slide rod 9 is fixedly connected inside the groove 8, and the slide block 7 is slidably connected to the surface of the slide rod 9. The slide block 7 is used to limit the position of the rotating shaft 10. When the slide block 7 slides inside the groove 8, it can drive the rotating shaft 10 to move back and forth together. The slide rod 9 can improve the stability of the slide block 7 during movement.

[0033] Reference Figure 1A hydraulic rod 6 is mounted on the surface of the base 5, and a slide 7 is fixedly connected to the top of the hydraulic rod 6. Activating the hydraulic rod 6 can drive the slide 7 to move back and forth, thereby driving the rotating shaft 10 to move back and forth.

A first motor gear 18 is fixedly connected to the top of the first motor 19, and the cylindrical gear 2 is meshed above the first motor gear 18. When it is necessary to rotate the fermentation tank 1, the first motor 19 can be started, which drives the first motor gear 18 to rotate through the motor shaft, thereby driving the cylindrical gear 2 and the fermentation tank 1 to rotate.

[0035] Reference Figure 1 and Figure 4 A rotating shaft gear 11 is fixedly connected to the surface of the rotating shaft 10 and to the front end of the front baffle 24. A second motor gear 14 is meshed with the lower end of the rotating shaft gear 11. Rotating the second motor gear 14 can drive the rotating shaft gear 11 to rotate.

[0036] Reference Figure 1 A second motor 15 is mounted on the front end of the second motor gear 14, and a slide block 7 is fixedly connected to the front end of the second motor 15. When it is necessary to rotate the rotating shaft 10, the second motor 15 on the side of the slide block 7 is started, which drives the second motor gear 14 to rotate through the motor shaft, thereby driving the rotating shaft gear 11 and the rotating shaft 10 to rotate.

[0037] Reference Figure 4 An air inlet groove 28 is provided inside the rotating shaft 10 near the filter screen 20. A filter baffle 27 is fixedly connected to the rear end of the rotating shaft 10, and a sample container 26 is located at the rear end of the filter baffle 27. Before fermentation, the sample container 26 can be opened, and sample black tea raw materials can be added into the sample container 26. The filter baffle 27 can block the raw materials in the sample container 26 from entering the air inlet groove 28. During fermentation, if abnormal gas data is detected, the rear cover 22 and the sample container 26 can be opened to remove the sample black tea raw materials for testing and analysis.

[0038] Reference Figure 1 and Figure 3 A rear cover 22 is rotatably connected to the rear end of the fermentation cylinder 1, and a feeding plate 17 is rotatably connected to the surface of the fermentation cylinder 1. Raw materials can be added inside by opening the feeding plate 17.

[0039] The implementation principle of the dark tea pile fermentation device of this application is as follows: The rotating shaft 10 inside the fermentation cylinder 1 can stir the dark tea inside through the stirring blade 23. The rotation direction of the rotating shaft 10 is opposite to that of the fermentation cylinder 1, which can improve the stirring effect. The threaded groove 16 opened at the front end of the interior of the fermentation cylinder 1 can be used to thread a front baffle 24. The front baffle 24 is located on the surface of the rotating shaft 10 and can rotate. The rotating shaft 10 can slide back and forth inside the fermentation cylinder 1, thereby driving the front baffle 24, stirring blade 23, and rear baffle 21 on the surface of the rotating shaft 10 to move into the interior of the fermentation cylinder 1. In use, the hydraulic rod 6 on the surface of the fermentation cylinder 1 can be used to drive the slide 7 to slide to the rear end, thereby driving the rotating shaft 10 inside the slide 7 to move to the rear end of the fermentation cylinder 1.

[0040] When the front baffle 24 on the surface of the rotating shaft 10 moves to the threaded groove 16, the front baffle 24 can be held and rotated, and installed inside the front end of the fermentation cylinder 1. Then, the feeding plate 17 is opened to add black tea raw materials into the fermentation cylinder 1. The space between the rear baffle 21 and the front baffle 24 is used to place the black tea raw materials. During fermentation, the raw materials can be turned over using a stirring device. Gas generated during production can flow through the filter screen 20 to the air inlet groove 28 inside the rotating shaft 10. When it is necessary to detect the gas in the fermentation cylinder 1, the gas in the air inlet groove 28 can be extracted and analyzed using the gas detection station 13 and the vent pipe 12 to understand the fermentation environment data inside the fermentation cylinder 1. Before fermentation, the sample container 26 can be opened, and sample black tea raw materials can be added into the sample container 26. The filter baffle 27 can block the raw materials in the sample container 26 from entering the air inlet groove 28. During fermentation, if the detected gas data is abnormal, the rear cover 22 and the sample container 26 can be opened to remove the sample black tea raw materials for testing and analysis. When discharge is required, the front baffle 24 can be rotated by holding handle 25, and the slide 7 can be moved forward by activating hydraulic rod 6, pushing the raw material out through rear baffle 21. During the fermentation process, this device can sample and test the internal gas and raw materials, making it easier for staff to maintain the environment required for internal fermentation and improve production quality.
