Description

Technical Field

[0001] This invention relates to the field of tea-frying equipment technology, and in particular to a secondary fixation process for Liubao tea after piling. Background Technology

[0002] Tea fixation refers to a tea-making process that uses high temperatures to destroy and deactivate the oxidase activity in fresh tea leaves, inhibiting the enzymatic oxidation of tea polyphenols and other substances, evaporating some of the moisture from the fresh leaves, softening the tea leaves, making them easier to roll and shape, and simultaneously removing the grassy odor and promoting the formation of a good aroma. This is essentially the traditional tea-frying process. Current fixation methods often still rely on traditional high-temperature fixation. Few teas require a second fixation, such as Liubao tea, which undergoes a second high-temperature fixation after fermentation to further improve the quality of the tea. This requires appropriate fixation equipment.

[0003] Existing fixation devices typically involve placing tea leaves in a high-temperature wok and continuously stirring them to achieve fixation. During this process, it's crucial to ensure even heating of the tea leaves. Because tea leaves are relatively fragile, the stirring frequency must be controlled based on the quantity of tea leaves to prevent damage to their integrity and quality. However, existing devices often only perform simple stirring, resulting in excessive piling of tea leaves afterward, failing to guarantee even heating. Furthermore, during the wok's rotation and stirring process, the tea leaves, containing a certain amount of moisture, adhere to the wok's inner wall due to the high temperature and humidity, leading to overheating and excessive drying. This can also affect the heating of other tea leaves, impacting the fixation process and compromising the overall quality of the tea. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the background art by proposing a secondary fixation process for Liubao tea after piling.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A secondary fixation process for Liubao tea after piling, comprising the following steps:

[0007] S1. Place the tea leaves into the rotating drum and close the lid. The motor drives the guide teeth to rotate. The rotation of the rotating drum is driven by the meshing effect between the guide teeth and the rotating drum. The tea leaves are stir-fried and de-enzymed by the heating effect of the rotating drum.

[0008] S2. Depending on the amount of tea leaves added, the lever drives the bushing to slide along the connecting shaft, forcing one of the differential gears to mesh with an adjacent transmission gear, ensuring that the turntable can rotate at different speeds depending on the amount of tea leaves. At this time, the transmission mechanism can achieve different rotation speeds. Different rotation speeds can be achieved by driving the connecting gear with the bevel gear, forcing the lever to turn the accumulated tea leaves at different frequencies.

[0009] S3. By connecting the air injection box and the conduit, and by spraying air onto the inner wall of the rotating drum through the air jet plate, the tea leaves adhering to the inner wall of the rotating drum are forced to fall off, preventing the tea leaves from being overheated and drying out, thus avoiding affecting the quality of the tea leaves. The tea leaves that still adhere to the inner wall of the rotating drum after the air jet cleaning are cleaned by a scraper and temporarily collected by a cleaning box, further ensuring the overall quality of the tea leaves.

[0010] S4. Air is blown into the interior of the connecting cylinder through the connector and the air groove. The surface of the connector and the push pin are cleaned by blowing air through the air port and the guide hole to prevent tea leaves from adhering.

At the same time, the connection between the flow port and the guide hole cleans the tea leaves adhering to the surface of the detonator, further ensuring the uniformity of heating of all tea leaves.

[0023] 3. Use a scraper to clean the tea leaves that still adhere to the inner wall of the rotating drum after the air jet cleaning. This prevents the over-dried tea leaves from hindering the heating effect of the rest of the tea leaves and prevents them from breaking and falling into the tea pile, thus affecting the overall quality of the tea.

[0024] In summary, this invention utilizes the rotating mechanism of the connecting cylinder to drive the paddle pins in the frying process, spreading and turning the accumulated tea leaves. Different frequencies of turning are achieved through the meshing of different differential gears and transmission gear supports, ensuring uniform heating and preventing damage to the tea leaves. A jet plate cleans the tea leaves adhering to the inner wall of the rotating cylinder using air jets, preventing overheating and damage. Air nozzles and guide holes further clean the tea leaves adhering to the paddle pins and the surface of the connecting cylinder, ensuring uniform heating of all tea leaves.

[0040] Reference Figures 1-12 A secondary fixation process for Liubao tea after piling, including the following steps:

[0041] S1. Place the tea leaves into the rotating drum 5 and close the cover 42. The motor 3 drives the guide tooth 4 to rotate. The meshing effect between the guide tooth 4 and the rotating drum 5 drives the rotating drum 5 to rotate. The tea leaves are stir-fried and de-enzymed by the heating effect of the rotating drum 5.

[0042] S2. Depending on the amount of tea leaves added, the lever 39 drives the bushing 9 to slide along the connecting shaft 8, forcing one of the differential gears 10 to mesh with an adjacent transmission gear 13, ensuring that the turntable 7 can rotate at different speeds depending on the amount of tea leaves. At this time, the transmission mechanism 14 can achieve different rotation speeds. The bevel gear 16 can drive the connecting gear 19 to achieve different rotation speeds, forcing the lever 17 to turn the piled tea leaves at different frequencies.

[0043] S3. Through the connection between the air injection box 21 and the conduit 22, and by spraying air onto the inner wall of the rotating drum 5 through the air jet plate 31, the tea leaves adhering to the inner wall of the rotating drum 5 are forced to fall off, preventing the tea leaves from being overheated and drying out, thus avoiding affecting the quality of the tea leaves. The scraper 33 is used to clean the tea leaves that still adhere to the inner wall of the rotating drum 5 after the air jet cleaning, and the cleaning box 30 is used to temporarily collect them, further ensuring the overall quality of the tea leaves.

[0044] S4. Air is blown into the interior of the connecting cylinder 15 through the connector 23 and the air groove 25. The surface of the connector 23 and the surface of the push post 17 are cleaned by blowing air through the air outlet 27 and the guide hole 29 to prevent tea leaves from adhering. The engagement effect between the toothed ring 36 and the mating tooth 37 drives the screw 34 to rotate. The threaded connection effect drives the push plate 35 to slide along the cleaning groove 32 to push the tea leaves collected inside the cleaning box 30.

[0045] Reference Figures 1-12 A device for the secondary fixation process of Liubao tea after stacking includes a base 1, a platform 2 hinged to the top of the base 1, a motor 3 fixedly connected inside the platform 2, a guide gear 4 fixedly connected to the output end of the motor 3 via a coupling, a rotating cylinder 5 meshing with one side of the surface of the guide gear 4, the rotating cylinder 5 rotatably connected above the platform 2, a guide plate 6 fixedly connected to the output end of the motor 3, a turntable 7 connected to one side of the guide plate 6 via a belt drive, a connecting shaft 8 fixedly connected to one side of the turntable 7, a bushing 9 slidably connected to the surface of the connecting shaft 8, three differential gears 10 sequentially fixedly connected to the surface of the bushing 9, the diameter of the three differential gears 10 increasing from the connecting plate 11 towards the turntable 7, a connecting plate 11 rotatably connected inside the rotating cylinder 5, a drive shaft 12 fixedly connected to one side of the surface of the connecting plate 11, three drive gears 13 fixedly connected to the surface of the drive shaft 12, the diameter of the three drive gears 13 decreasing sequentially from the turntable 7 towards the connecting plate 11, and the differential gears 10... It can mesh with the transmission gear 13. The transmission mechanism 14 is fixedly connected to the surface of the transmission shaft 12 near the connecting plate 11. The other end of the transmission mechanism 14 is fixedly and rotatably connected to the surface of the connecting plate 11. Two connecting cylinders 15 are symmetrically and rotatably connected to the other side of the surface of the connecting plate 11. The connecting cylinders 15 are rotatably connected to the inside of the rotating cylinder 5. The inside of the connecting cylinder 15 is fixedly connected with a bevel gear 16. The surface of the connecting cylinder 15 is rotatably connected with a lever 17. One end of the lever 17 passes through the inside of the connecting cylinder 15. The end of the lever 17 that passes through the inside of the connecting cylinder 15 is fixedly connected with a gear 18. Two adjacent gears 18 mesh with each other. The surface of one gear 18 near the bevel gear 16 is fixedly connected with a connecting tooth 19. The connecting tooth 19 meshes with the bevel gear 16. One side of the surface of the bevel gear 16 is fixedly connected with a rotating shaft 20. The rotating shaft 20 passes through the connecting plate 11. The end of the rotating shaft 20 that passes through the outside of the connecting plate 11 is fixedly connected to the transmission mechanism 14.

[0046] Depending on the amount of tea leaves placed inside the rotating drum 5, the sliding bushing 9 forces two differential gears 10 of different diameters to mesh with the transmission gears 13, enabling the connecting disc 11 to rotate at different speeds. At this time, the two connecting drums 15 rotate inside the rotating drum 5. Through the transmission effect of the transmission structure, the two rotating shafts 20 are forced to rotate while following the connecting drums 15. Thus, through the meshing effect of the bevel gear 16 and the three connecting gears 19, the several deflectors 17 on the surface of the connecting drum 15 are forced to rotate. When the connecting drum 15 contacts the tea pile, the rotating deflectors 17 spread and turn the tea pile, ensuring the uniformity of the tea leaves being heated and ensuring the effect of fixing.

[0047] An air injection box 21 is fixedly connected to the top of the base 2. Two conduits 22 are connected to the top of the air injection box 21. One end of one conduit 22 is connected to a connector 23. A baffle 24 is rotatably connected to the surface of the connecting plate 11. The connecting plate 11 and the baffle 24 are connected through each other. The connector 23 is fixedly connected to the baffle 24. Two symmetrical air vents 25 are provided inside the connecting plate 11. Two symmetrical air outlets 26 are provided on the side of the connecting plate 11 near the connecting cylinder 15. The air outlets 26 are connected to the inside of the connecting cylinder 15. One end of the air vent 25 is connected to the air outlet 26, and the other end of the air vent 25 is connected to the connector 23 through the baffle 24. The surface of the connecting cylinder 15 is provided with an air blowing port 27. One end of the air blowing port 27 is connected to the interior of the connecting cylinder 15. The interior of the connecting cylinder 15 is provided with a flow outlet 28. Both ends of the flow outlet 28 are connected to guide holes 29. The two guide holes 29 are located on both sides of the push post 17. A cleaning box 30 is fixedly connected to the surface of the baffle 24 near the connecting cylinder 15. One side of the surface of the cleaning box 30 is connected to an air jet plate 31. Another conduit 22 is connected to the cleaning box 30 through a connecting ring 46. A cleaning groove 32 is provided inside the cleaning box 30. A scraper 33 is fixedly connected to the top of the cleaning groove 32. The scraper 33 is slidably connected to the inner wall of the rotating cylinder 5.

[0048] The air injection box 21 delivers high-pressure air to the connector 23 and the cleaning box 30 through two conduits 22. The connector 23 is connected to the two ventilation slots 25 through the rotation of the connecting plate 11. High-pressure air is injected into the interior of the connecting cylinder 15 through the connection between the ventilation slots 25 and the air outlet 26. At this time, the high-pressure air inside the connecting cylinder 15 blows the tea leaves adhering to the surface of the connecting cylinder 15 through the air blowing port 27. At the same time, the high-pressure air inside the connecting cylinder 15 enters the guide hole 29 through the drain port 28 and cleans the tea leaves adhering to the surface of the pusher 17 through the guide hole 29. This can further ensure the uniformity of heating during the tea leaf fixation process.

[0049] The high-pressure air entering the cleaning box 30 is blown out through the jet plate 31. Since the tea leaves are subjected to high temperature and humidity during the withering process, they inevitably adhere to the inner wall of the rotating drum 5. The high-pressure air blown out through the jet plate 31 can clean the tea leaves adhering to the inner wall of the rotating drum 5, preventing the tea leaves from being overheated and over-dried, and further ensuring the uniform heating effect of the tea leaves. At the same time, the scraper 33 scrapes off the tea leaves that have not been blown off and collects them into the cleaning trough 32 through the cleaning box 30. This can prevent the over-dried tea leaves from always adhering, avoid the dried tea leaves from breaking and falling into the tea pile, and avoid affecting the overall quality of the tea.

[0050] A screw 34 is rotatably connected inside the cleaning groove 32. A push plate 35 is threadedly connected to the surface of the screw 34. The push plate 35 is slidably connected inside the cleaning groove 32. The end of the cleaning groove 32 away from the connecting ring 46 passes through the cleaning box 30. A gear ring 36 is fixedly connected to the inner surface of the rotating drum 5. The gear ring 36 is located on the side close to the drive shaft 12. A mating tooth 37 is rotatably connected to the surface of the connecting ring 46. The mating tooth 37 meshes with the gear ring 36 and is fixedly connected to the screw 34.

[0051] The rotation of the rotating drum 5 forces the gear ring 36 to drive the mating gear 37 to rotate, which in turn drives the screw 34 to rotate. Through the effect of the threaded connection, the push plate 35 can slide along the cleaning groove 32, pushing out the over-dried tea collected in the cleaning groove 32, making it easier to remove defective products.

[0052] The transmission mechanism 14 includes two transmission wheels 141 and two connecting wheels 142. The two transmission wheels 141 are fixedly connected to the surface of the transmission shaft 12, and the two connecting wheels 142 are symmetrically rotatably connected to the surface of the connecting disc 11. The transmission wheels 141 and the connecting wheels 142 are connected by belt drive.

[0053] The rotation of the drive shaft 12 can drive the connecting disc 11 and the drive wheel 141 to rotate. The rotation of the drive wheel 141 can drive the connecting wheel 142 to rotate through the transmission effect of the belt. While the rotating shaft 20 and the connecting wheel 142 rotate with the connecting disc 11, the connecting wheel 142 will rotate on its own, ensuring the normal operation of the shift post 17.

[0054] One side of each of the three differential gears 10 is slidably connected to a connecting block 38. A lever 39 is fixedly connected between the three connecting blocks 38. A slider 40 is hinged to the other end of the lever 39. A positioning plate 41 is fixedly connected to the top of the base 2. The slider 40 is slidably connected to the positioning plate 41, and the slider 40 can be engaged with the positioning plate 41.

[0055] The slider 40 drives the lever 39 to slide, which in turn drives the three differential gears 10 to slide through the connecting block 38. This forces the two differential gears 10 with different diameters to mesh with the transmission gear 13, thereby ensuring that the transmission shaft 12 achieves different rotation speeds. This ensures the spreading and turning effect of the connecting cylinder 15 and the lever 17 on the tea pile, and prevents the tea from being damaged due to excessively fast turning frequency, or prevents the tea from being heated evenly due to excessively low turning frequency.

[0056] A cover 42 is hinged to one side of the surface of the rotating drum 5. An opening 43 is provided through the surface of the cover 42. The opening 43 is inserted into the cleaning box 30. A telescopic column 44 is hinged to the top of the base 1. The other end of the telescopic column 44 is hinged to the bottom of the platform 2.

[0057] The telescopic column 44 extends and retracts, forcing the base 1 and the platform 2 to rotate. After stir-frying and blanching, the platform 2 rotates to force the opening of the rotating drum 5 to face downwards, facilitating the discharge of the blanched tea leaves. The cover 42 also prevents tea leaves from falling or foreign objects from entering the rotating drum 5 during the stir-frying process.

[0058] The surface of the baffle 24 is provided with a connecting groove 45, and the surface of the connecting plate 11 is fixedly connected with a connecting ring 46, and the connecting ring 46 is inserted into the connecting groove 45. The surface of the baffle 24 near the drive shaft 12 is fixedly connected to the base 2.

[0059] The connection between the connecting groove 45 and the connecting ring 46 ensures the stable rotation of the connecting plate 11. Furthermore, the fixed connection between the baffle 24 and the base 2 ensures the stability of the baffle 24 and prevents it from rotating with the connecting plate 11.

[0060] The working principle and usage of this invention are explained in detail below: In use, the first step is to put the tea leaves into the rotating drum 5 and close the cover 42. The motor 3 drives the guide tooth 4 to rotate. The meshing effect between the guide tooth 4 and the rotating drum 5 drives the rotating drum 5 to rotate. The rotating drum 5 can be heated to complete the stir-frying and blanching of the tea leaves. Depending on the amount of tea leaves put in, the lever 39 drives the bushing 9 to slide along the connecting shaft 8, forcing one of the differential teeth 10 to mesh with an adjacent transmission tooth 13. This ensures that the turntable 7 can rotate at different speeds depending on the amount of tea leaves. At this time, the transmission mechanism 14 can achieve different rotation speeds. The bevel tooth 16 can drive the connecting tooth 19 to achieve different rotation speeds, forcing the lever 17 to turn the piled tea leaves at different frequencies.

[0061] The second step involves connecting the air injection box 21 and the conduit 22, and using the air jet plate 31 to spray air onto the inner wall of the rotating drum 5. This forces the tea leaves adhering to the inner wall of the rotating drum 5 to fall off, preventing the tea leaves from drying out due to excessive heat and affecting their quality. The scraper 33 then cleans the tea leaves that remain adhering to the inner wall of the rotating drum 5 after the air jet cleaning, and temporarily collects them in the cleaning box 30 to further ensure the overall quality of the tea leaves. Air is blown into the connecting cylinder 15 through the connector 23 and the air vent 25, and the surfaces of the connector 23 and the push post 17 are cleaned through the air outlet 27 and the guide hole 29 to prevent tea leaves from adhering. The meshing effect between the toothed ring 36 and the mating tooth 37 drives the screw 34 to rotate, and the threaded connection causes the push plate 35 to slide along the cleaning groove 32, pushing the tea leaves collected inside the cleaning box 30.

[0062] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0063] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
