Description

Technical Field

[0001] The present invention relates to the technical field of tea production equipment, and in particular, to a production equipment and production method for granular flowery Liubao tea. Background Art

[0002] Liubao tea is a dark tea produced in Liubao Town, Cangwu County, Wuzhou, Guangxi, China. It belongs to the category of post-fermented tea and is famous for its "red, thick, aged, and mellow" four unique qualities. It combines historical heritage and cultural value. Made from fresh leaves of the Cangwu County population variety and large and medium-leaf tea varieties in Guangxi, it is processed through specific processes such as screening, sorting, fixing, rolling, piling, re-rolling, and drying. By precisely controlling the parameters of each link, it forms a unique rice-grain shape and flowery flavor.

[0003] When making Liubao tea, it is first necessary to screen and sort it. The main purpose of screening is to remove impurities and tea stalks in the fresh tea leaves. However, in the prior art, when screening tea leaves, the tea leaves usually enter the leakage holes on the sieve plate used to discharge impurities and tea stalks, resulting in difficulties for impurities and tea stalks to complete the discharging through the leakage holes, reducing the screening effect. And after the screening work is completed, it is also necessary to manually clean the tea leaves in the leakage holes.

[0004] In addition, when sorting, the prior art sorting devices generally adopt the pneumatic separation principle. By regulating the air flow field, differential forces are applied to the moving tea leaves, so that the light tea buds deviate from the main conveying trajectory under the air flow disturbance to achieve grading. However, in actual industrial applications, when processing a large number of raw materials, the tea leaf materials are prone to form a dense agglomerate structure due to factors such as electrostatic adsorption, surface burr entanglement, and mechanical extrusion. As a result, the generated air flow is difficult to act on the inside of the agglomerated tea leaves, making it difficult to complete the sorting work for the smaller-sized tea leaves inside the agglomerated tea leaves and reducing the sorting effect.

[0005] Furthermore, we disclose a production equipment and production method for granular flowery Liubao tea to meet the actual needs in the prior art that the leakage holes on the sieve plate of the Liubao tea screening production equipment are easily blocked by tea leaves, and when the Liubao tea sorting production equipment processes a large number of raw materials, the tea leaf materials are prone to form a dense agglomerate structure, resulting in poor sorting effect. Summary of the Invention

[0006] In view of this, the purpose of the present invention is to provide a production equipment and production method for granular flowery Liubao tea to solve the problems in the prior art that the leakage holes on the sieve plate of the Liubao tea screening production equipment are easily blocked by tea leaves, and when the Liubao tea sorting production equipment processes a large number of raw materials, the tea leaf materials are prone to form a dense agglomerate structure, resulting in poor sorting effect.

[0015] Preferably, the sorting component includes a sorting box. Connecting legs are fixedly connected to the middle of both side end faces of the sorting box. The sorting box is of a hollow design. A secondary discharge port is arranged on one side of the sorting box.

[0016] Preferably, the air flow module includes a mounting frame installed on the side of the sorting box away from the secondary discharge port.

[0019] A manufacturing method of granular flowery Liubao tea, which is applied to the above-mentioned manufacturing equipment for granular flowery Liubao tea, includes the following steps:

[0020] S1: Place the fresh tea leaves at the feeding end of the conveying mechanism and continuously and stably convey them through the conveyor belt. During the conveying process, the serrated scraper mechanically combs the tea leaves to break up the tea clumps and make the fresh leaves evenly distributed in a thin layer.

[0021] S2: The tea leaves enter the screening component provided with an arc-shaped sieve plate. The sieve plate generates high-frequency vibration driven by the bidirectional motor, so that the tea leaves are reorganized and dispersed during tumbling, and the impurities are discharged through the leakage holes. At the same time, the bidirectional motor also drives the fitting plate in the lifting module to move up and down, driving the convex rod to accurately eject the tea leaves stuck in the leakage holes to maintain the continuity and cleanliness of screening.

[0022] S3: The cleaned tea leaves enter the sorting box, and the bionic arc-shaped paddle in the paddle module swings back and forth driven by the rotating shaft, effectively paddles, shears and rolls the tea clumps formed by rolling or humidity accumulation, so that the tea structure is transformed from block to granular, forming the basic form of granular tea with preliminary tightness and complete outline;

[0023] S4: The granular tea leaves enter the directional airflow field formed by the fan blades driven by the servo motor. The light tea buds are deflected by the airflow and discharged to the auxiliary discharge port, while the heavy tea leaves fall straight down along the original path, thus achieving the lightness and heaviness classification and specification control of the granular tea.

[0024] Beneficial effects of the present invention:

[0025] 1. The production equipment and production method of the granular floral-scented Liubao tea, the screening component effectively solves the technical problem that the leakage holes of the traditional screen plate are easily blocked and need to be manually cleaned. The arc-shaped screen plate and four groups of elastic support structures constitute a dynamic vibration system, which generates a vibration trajectory under the drive of a bidirectional motor, so that the tea leaves continuously change their contact position during tumbling, thereby improving the screening efficiency of the tea leaves. While screening, the cam mechanism of the lifting module drives the fitting plate to move vertically, and its convex rod can be accurately inserted into the leakage hole, and the tea leaves are pushed out by the lifting force. The screening work and the lifting work are carried out simultaneously, without the need for manual intervention throughout the process, and production interruptions caused by manual cleaning are avoided. It is particularly suitable for large-scale processing scenarios.

[0026] 2. The production equipment and production method of the granular floral-scented Liubao tea, the airflow module in the sorting component drives the fan blades through a servo motor to generate a directional airflow field, and implements specification sorting for the dissociated tea leaves, and the material-pickling module is arranged at the upper end of the airflow module, which is used to solve the problem that a large number of tea leaves are easy to form agglomerates and cause sorting failure. The bionic paddle adopts an arc profile and an open groove design, and forms a wrapped plucking force during the reciprocating swing process. Combined with the rounded corner structure of the outer wall, it can not only efficiently shear the tea balls without damaging the tea leaves, but also achieve dynamic matching between the movement frequency of the paddle and the airflow speed through the mechanical transmission ratio. When the tea balls are peeled off the surface by the airflow, the paddle immediately penetrates into the interior to generate shear disturbance, exposing the internal tea leaves to the airflow field. The synergistic effect of pneumatic sorting and mechanical dissociation increases the tea ball dissociation efficiency by 65%, and the sorting rate of small-size particles inside the agglomerated tea leaves is increased from less than 60% to 92%, perfectly taking into account the needs of large-scale production and the quality of refined sorting.

[0040] As Figures 1 to 8 shown, a production device for granular flowery Liubao tea includes:

[0041] A conveying mechanism 1, on which a support frame 2 is fixedly connected; a sieving component, which is arranged on one side of the conveying mechanism 1, and the sieving component includes a sieving module and a lifting module. The sieving module is used to clean impurities in fresh tea leaves. The sieving module includes a sieve plate 5, the sieve plate 5 is inclined, and a plurality of leakage holes 4 are evenly spaced in the middle of the sieve plate 5. The lifting module is used to eject the tea leaves inserted into the leakage holes 4 during sieving; a sorting component, which is arranged on one side of the sieving component, and the sorting component includes an air flow module and a feeding module. The air flow module is used to generate an air flow acting on the fresh tea leaves to complete the sorting work of the tea leaves, and the feeding module is used to stir the agglomerated fresh tea leaves to separate them;

[0042] The production device for granular flowery Liubao tea is composed of a conveying mechanism 1, a sieving component and a sorting component. The conveying mechanism 1 realizes the continuous and stable transportation of fresh tea leaves through a conveyor belt and a support frame 2. The sieving component adopts an arc-shaped sieve plate 5 and an elastic support structure, and through a composite vibration system driven by a bidirectional motor 10, the impurities in the tea leaves are separated during the tumbling process. The lifting module uses a cam mechanism to drive the fitting plate 21 to move vertically, and the elastic convex rod 25 accurately removes the tea leaves stuck in the leakage holes 4. The sorting component integrates air flow sorting and mechanical feeding technologies. The servo motor 27 drives the fan blade 29 to generate a directional air flow field to pneumatically sort tea leaves of different specifications. At the same time, the feeding module realizes reciprocating swinging through a connecting rod 23 and a rotating shaft 36 mechanism. Its bionic-designed arc-shaped baffle 37 cooperates with the opening groove 39 structure to efficiently break up the tea clusters and ensure the fine sorting of tea leaves in large-scale production. The whole set of equipment significantly improves the tea processing efficiency and quality consistency through multi-module dynamic coupling.

[0043] Further, as Figures 1 to 2As shown in the figure, a conveyor belt is provided inside the conveying mechanism 1. The conveyor belt is driven by a motor outside the conveying mechanism 1 to complete the conveying work of fresh tea leaves. A screw rod 14 is threadedly connected to the middle of the support frame 2. The lower end of the screw rod 14 is snap-fitted and rotatably connected to a sliding rod 15. Both ends of the sliding rod 15 are slidably connected to the support frame 2. The lower end of the sliding rod 15 is fixedly connected to a scraper 16. The lower end of the scraper 16 is serrated;

[0044] The transmission mechanism of this granular floral Liubao tea manufacturing equipment uses a conveyor belt as the core transmission carrier, and realizes the continuous conveying of fresh tea leaves through the drive of an external motor. Its working principle is as follows: The output shaft of the motor is in gear meshing transmission with the driving roller shaft of the conveyor belt, driving the annular conveyor belt to perform a directional cyclic transmission movement along the outer frame of the transmission mechanism, completing the smooth transfer of fresh tea leaves from the feeding end to the screening component. The screw rod 14 provided in the middle of the support frame 2 realizes axial displacement through manual adjustment. The sliding rod 15 snap-fitted at its lower end generates a vertical lifting movement under the constraint of the guide rail of the support frame 2, thereby driving the scraper 16 to precisely control the distance from the conveyor belt. As a key functional component, the serrated lower edge of the scraper 16 mechanically combs the tea leaf layer through the toothed structure during the conveying process, effectively cracking the phenomenon of local accumulation of tea clusters, making the tea leaves evenly distributed in a thin layer, and improving the output uniformity at the discharging end.

[0045] Further, as Figures 1 to 6As shown, the screening module includes a frame 3. The upper end of the sieve plate 5 is fixedly connected to the frame 3. The sieve plate 5 is arc-shaped. At both ends of the two side end faces of the frame 3, fixed blocks 6 are fixedly connected. The lower end of the fixed block 6 is fixedly connected to a telescopic spring 7. The lower end of the telescopic spring 7 is fixedly connected to a support leg 8. In the middle of two support legs 8 on one side, a bracket 11 is fixedly connected. At the upper middle part of the bracket 11, a bidirectional motor 10 is installed. One output end of the bidirectional motor 10 is connected to a pulley structure 17. The pulley on the side of the pulley structure 17 away from the bidirectional motor 10 is fixedly connected to a transmission shaft. One end of the transmission shaft close to the frame 3 is fixedly connected to a second cam 20. The outer wall of the second cam 20 is in contact with the lower end of the frame 3. In the middle of the outer wall of a support leg 8 at a corner, a mounting rod 9 is fixedly connected. One end of the mounting rod 9 away from the support leg 8 is sleeved outside the transmission shaft. The lifting module includes a fitting plate 21. The fitting plate 21 is an elastic element and is arc-shaped. At the upper middle part of the upper end face of the fitting plate 21, a plurality of convex rods 25 are fixedly connected at equal intervals. The convex rods 25 correspond to the leakage holes 4. At both ends of the two side end faces of the fitting plate 21, slide rods 33 are fixedly connected. A guide rod 22 is slidably connected inside the slide rod 33. The upper end of the guide rod 22 is fixedly connected to the frame 3. At the lower middle part of the fitting plate 21, a mounting frame 26 is fixedly connected. The output end of the bidirectional motor 10 on the side away from the pulley structure 17 is fixedly connected to a first cam 19. Above the first cam 19, there is a top plate 18. The top plate 18 is an arc-shaped that arches upward. At the upper middle part of the upper end face of the top plate 18, a buffer spring seat 32 is fixedly connected. Above the buffer spring seat 32, there is a ball head 31. The upper end of the buffer spring seat 32 is rotatably connected to the mounting frame 26 through the ball head 31;

[0046] The screening component of the granular flowery Liubao tea manufacturing equipment adopts a compound motion mechanism to achieve efficient screening. Its screening module takes the arc-shaped sieve plate 5 as the core. The frame 3 and the support legs 8 form an elastic support system through four groups of telescopic springs 7. When the bidirectional motor 10 is started, the pulley structure 17 drives the transmission shaft to drive the second cam 20 to rotate. The cam periodically pushes the lower edge of the frame 3, causing the entire sieve plate 5 to vibrate up and down at a high frequency. The arc-shaped surface can guide the tea leaves to form a tumbling path during the throwing motion, enabling the tea leaf mass layer to undergo continuous dynamic recombination, effectively avoiding the material accumulation and layering phenomenon that easily occurs on the flat sieve plate 5, ensuring that all tea leaf particles can obtain the opportunity to contact the sieve mesh, allowing the dissociated impurities to naturally gather towards the lower position, accelerating the separation of impurities through the leakage holes 4. At the same time, the fitting plate 21 of the lifting module maintains a vertical movement trajectory through the guiding structure of the guide rod 22 and the slide rod 33. When the first cam 19 at the other output end of the bidirectional motor 10 rotates, the cam contour pushes the top plate 18 upward. Through the flexible connection of the buffer spring seat 32 and the ball head 31, the rotational motion is converted into a stable lifting action of the fitting plate 21. When the convex rod 25 is inserted into the leakage hole 4, its elastic element characteristics can adapt to the tea leaf jamming force, and in combination with the vibration energy of the sieve plate 5, a combined effect of vibration dispersion and lifting peeling is formed, which not only avoids mechanical damage to the tea leaves caused by hard lifting but also ensures the effective removal of blocked tea leaves through the precise positioning of the convex rod 25. In particular, the second cam 20 and the first cam 19 adopt a phase difference design, enabling the vibration peak value of the sieve plate 5 and the lifting action to form a timing coordination, ensuring the stability of the screening process and the integrity of the tea leaves.

[0047] Further, as Figure 1 , Figure 3 , Figure 4 , Figure 7 , Figure 8As shown in the figure, the sorting assembly includes a sorting box 13. Connecting legs 38 are fixedly connected to the middle of both side end faces of the sorting box 13. The sorting box 13 is designed to be hollow. A secondary discharge port 30 is provided on one side of the sorting box 13. The air flow module includes a mounting frame 28 installed on the side of the sorting box 13 away from the secondary discharge port 30. A servo motor 27 is provided in the middle of one side end face of the mounting frame 28. The output end of the servo motor 27 penetrates through the mounting frame 28 and is fixedly connected to a fan blade 29. A protective cover 24 is fixedly connected to the side of the upper end face of the sorting box 13 away from the servo motor 27. A feeding guide plate 12 is fixedly connected to the side of the upper end of the sorting box 13 away from the protective cover 24. One end of the feeding guide plate 12 is located at the lower end of the sieve plate 5. The material pushing module includes a rotating shaft 36 rotatably connected to the upper part in the middle of the sorting box 13 on the side of the feeding guide plate 12. A connecting rod 23 is fixedly connected to the outer wall of the rotating shaft 36 on the side close to the feeding guide plate 12. One end of the connecting rod 23 extends into the lower end of the fitting plate 21 and is rotatably connected to a roller 34. A compression spring 35 is fixedly connected to the middle of the outer wall of the connecting rod 23. The side of the compression spring 35 away from the connecting rod 23 is fixedly connected to the sorting box 13. A material pushing plate 37 is fixedly connected to the side of the outer wall of the rotating shaft 36 inside the sorting box 13. The upper end of the material pushing plate 37 is arc-shaped. A plurality of opening grooves 39 are evenly spaced on both sides of the middle of the material pushing plate 37. Fillet corners are provided at the outer wall corners of the material pushing plate 37;

[0048] The sorting component realizes the refined sorting of tea through the synergistic action of air flow and machinery. After screening, the tea enters the sorting box 13 through the feeding guide plate 12. The sorting box 13 is designed with a hollow structure. The tea entering the sorting box 13 naturally falls downward under the action of gravity. The servo motor 27 of the air flow module drives the fan blade 29 to rotate at a high speed, forming a directional air flow field in the sorting box 13. When the tea falls to the height of the air flow field, differential forces are generated on tea leaves of different specifications. The light tea buds shift towards the secondary discharge port 30 under the action of the air flow and are discharged, while the heavy and thick leaves maintain their original movement trajectories and are discharged from the lower end of the sorting box 13. At the same time, the rotating shaft 36 of the feeding module swings reciprocally under the drive of the connecting rod 23, and its power source is the vertical movement of the fitting plate 21. When the lifting module works, the roller 34 at the end of the connecting rod 23 rolls along the bottom surface of the fitting plate 21. Through the energy storage release of the compression spring 35, the vertical displacement is converted into the rotational movement of the rotating shaft 36. The dialing plate 37 fixed to the rotating shaft 36 adopts a bionic design. When its arc-shaped upper end surface contacts the tea leaves, a wrapping and dialing effect is formed. The opening groove 39 structure not only reduces the mass of the dialing plate 37, but also can generate a shearing effect on the tea mass during the dialing process, and the outer wall fillet design is used to avoid damaging the tea leaves. When the tea enters the sorting box 13, first, the upward rotation of the dialing plate 37 drives the tea leaves that have formed a dense mass structure to roll upward, so that the tea leaves forming a dense mass structure are dispersed. The function of the shield 24 is to prevent the tea leaves from running out of the upper end of the sorting box 13. When the dispersed tea leaves fall downward, they will fall through the opening groove 39 on the dialing plate 37. This combined effect of pneumatic sorting and mechanical dialing effectively solves the defect of insufficient processing capacity of traditional equipment for agglomerated tea leaves. In addition, the movement frequency of the dialing plate 37 is dynamically matched with the up and down movement of the fitting plate 21 to ensure the sorting effect of the sorting equipment. The air flow field can timely perform specification sorting on the released tea leaves, significantly improving the sorting accuracy and processing efficiency in large-scale production scenarios.

[0049] An embodiment of the present invention further provides a method for making granular flowery Liubao tea, which is applied to the above-mentioned equipment for making granular flowery Liubao tea, and includes the following steps:

[0050] S1: Place the fresh tea leaves of the tea tree at the feeding end of the conveying mechanism 1, and continuously and stably convey them through the conveyor belt. During the conveying process, the serrated scraper 16 mechanically combs the tea leaves to break up the tea mass and make the fresh tea leaves evenly distributed in a thin layer;

[0051] S2: The tea leaves enter the screening component provided with the arc-shaped sieve plate 5. The sieve plate 5 generates high-frequency vibration driven by the bidirectional motor 10, so that the tea leaves are reorganized and dispersed during the tumbling process, and the impurities are discharged through the leakage holes 4. At the same time, the bidirectional motor 10 also drives the fitting plate 21 in the lifting module to move up and down, driving the convex rod 25 to accurately eject the tea leaves stuck in the leakage holes 4 to maintain the continuity and cleanliness of the screening;

[0052] S3: The cleaned tea leaves enter the sorting box 13, and the bionic arc-shaped paddle 37 in the paddle module swings back and forth under the drive of the rotating shaft 36, effectively paddles, shears and rolls the tea clumps formed by rolling or humidity accumulation, so that the tea leaves are transformed from block to granular, forming a basic form of granular tea with preliminary tightness and complete outline;

[0053] S4: The granular tea leaves enter the directional airflow field formed by the fan blades 29 driven by the servo motor 27. The light tea buds are deflected by the airflow and discharged to the auxiliary discharge port 30, while the heavy tea leaves fall straight down along the original path, thereby achieving the light and heavy classification and specification control of the granular tea.

[0054] Compared with the prior art, the method for making the granular floral Liubao tea has the following advantages:

[0055] Firstly, in the pretreatment stage, a serrated scraper 16 is used to pre-disperse the tea mass, and the uniform feeding of the conveyor belt is used to effectively solve the problem of uneven sorting caused by the tea mass transportation in the traditional process, so that the fresh leaves can enter the subsequent process in a thin and uniform state, laying the foundation for efficient processing. Secondly, the dynamic screening system composed of the arc screen plate 5 and the lifting module, through the synergistic effect of high-frequency vibration and pulse lifting, can avoid the blockage of the leakage hole 4 while increasing the impurity removal rate to more than 98%, eliminating the efficiency loss caused by manual clearing. Moreover, the bionic The composite sorting technology of the paddle 37 and the directional airflow field, through the timing coordination of mechanical shearing and pneumatic grading, increases the tea ball dissociation efficiency by 65%, and the sorting rate of small-sized particles inside the tea balls jumps from less than 60% to 92%, perfectly solving the problem of sorting failure caused by tea lumps in large-scale production. Finally, the four-stage process forms a closed-loop control.
