Description

Technical Field

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

[0002] In tea processing, fermentation (or "piling") is a key step in forming the unique quality and flavor of post-fermented teas such as black tea and Pu'er tea. Traditional tea fermentation often uses natural piling or manual turning, which is greatly affected by environmental temperature and humidity, making it difficult to control the uniformity of fermentation. In addition, it is labor-intensive and difficult to ensure hygiene.

[0003] To overcome the shortcomings of traditional methods, various tea fermentation devices have emerged in the existing technology. These devices typically include a closed or semi-closed fermentation chamber and are equipped with a simple turning mechanism, such as fixed rotating blades or rake teeth, for stirring the tea leaves inside the chamber. However, these devices generally suffer from the following drawbacks: the turning mechanism of existing devices is often fixed in one position or can only move in one direction, such as rotation or translation. This results in inconsistent turning effects on tea leaves in different areas and at different depths within the fermentation chamber. Tea leaves located in the middle, bottom, and corner areas of the chamber are prone to accumulating and compacting due to insufficient turning, causing local over- or under-fermentation and seriously affecting the uniformity of the overall fermentation quality. Therefore, a tea fermentation device for tea processing is proposed to solve the aforementioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a tea fermentation device for tea processing, which addresses the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a tea fermentation device for tea processing, including a fermentation box, wherein the fermentation box is used to provide a relatively closed fermentation space for tea, and its bottom is provided with support legs for supporting the fermentation box, and further includes: A turning mechanism is installed inside the fermentation box to turn the tea leaves during the tea fermentation process; A moving mechanism is located outside the fermentation tank and connected to the turning mechanism, used to drive the turning mechanism to move its position inside the fermentation tank during the operation of the turning mechanism; A shaking mechanism, located inside the fermentation box, is used to shake and disperse the tea leaves during the turning process; The turning mechanism includes through holes on the outer walls of the front and rear sides of the fermentation box. Each through hole has multiple arc-shaped grooves spaced vertically at the bottom of its inner wall. A cylindrical slider is slidably installed in the through hole. The two cylindrical sliders are rotatably connected by the same rotating shaft. The rotating shaft is arranged horizontally along the fermentation box, and its two ends pass through the corresponding through holes.

[0006] Preferably, the outer wall of the rotating shaft is fixedly fitted with a fixed sleeve, and multiple turning rods are fixedly connected at equal intervals along the circumferential direction on the outer wall of the fixed sleeve. The turning rods are located inside the fermentation box and are used to move and turn the tea leaves when the rotating shaft rotates. The cylindrical slider is designed to work with the arc-shaped groove, allowing the rotating shaft to move up and down along the trajectory of the arc-shaped groove during rotation, thereby changing the turning height of the turning rod inside the fermentation chamber.

[0007] Preferably, the inner wall of the fermentation box is provided with an arc-shaped plate, which is arranged in accordance with the movement trajectory of the turning rod, and the arc-shaped plate is hinged to the turning rod, so that while the turning rod rotates and turns the tea leaves, it drives the arc-shaped plate to rotate and adhere to the inner wall of the fermentation box, thereby scraping off the tea leaves attached to the inner wall surface.

[0008] Preferably, the moving mechanism includes a track fixedly connected to the outer wall of the fermentation tank and arranged along the through hole direction. A slider is slidably arranged on the track. Two L-shaped rods are fixedly connected to one side of the slider. An L-shaped sleeve is movably connected to the other end of each L-shaped rod. An installation block is fixedly connected between the two L-shaped sleeves. The installation block is rotatably connected to one end of the rotating shaft, so that when the slider moves along the track, it can drive the rotating shaft to move inside the fermentation tank. A motor is installed on the installation block. The output end of the motor is connected to the rotating shaft to drive the rotating shaft to rotate.

[0009] Preferably, a gear is fixedly sleeved on the outer wall of the rotating shaft, and a rack corresponding to the gear is fixedly installed on the outer wall of the fermentation tank. The gear and the rack mesh with each other. A sliding groove is opened on the front side of the rack, and a movable rod is slidably installed in the sliding groove. The movable rod is fixedly connected to an L-shaped sliding sleeve. A spring is sleeved on the outer wall of the L-shaped rod for pushing the cylindrical slider downward to abut against the arc-shaped groove. A fixed post is fixedly installed above the rack. A sliding sleeve is slidably sleeved on the outer wall of the fixed post, and a tension spring is sleeved on the outer wall of the fixed post for pulling the rack to maintain meshing with the gear.

[0010] Preferably, the shaking mechanism includes a separation plate slidably disposed within a rectangular through hole at the bottom of the fermentation tank. Multiple push rods are fixedly connected to the bottom of the separation plate, and a rectangular slider is fixedly connected to the bottom of each push rod. A partition is disposed inside the fermentation tank, and side plates are fixedly connected to the partition. The separation plate slides between the side plates. Multiple limiting posts are fixedly connected between the bottom of the inner wall of the fermentation tank and the partition. The rectangular slider is slidably sleeved on the outer wall of the limiting posts, and a second spring is sleeved on the outer wall of the limiting posts to provide a restoring elastic force after the separation plate is subjected to force.

[0011] Preferably, an installation groove is provided below the partition, and a baffle one and a baffle two are provided in the installation groove. The baffle one is fixedly connected to the bottom of the rectangular slider, and the baffle two is fixedly connected to the bottom of the inner wall of the fermentation tank. The baffle one and the baffle two are fitted together to block the installation groove.

[0012] Preferably, the inner walls of the fermentation box are respectively provided with arc-shaped gathering plates on both sides to guide the tea leaves during the operation of the turning mechanism and the shaking mechanism; the fermentation box is also provided with an arc-shaped rod in the shape of a U-shape, and the inner wall of the arc-shaped rod is provided with a bristle barrier to block the position of the through hole and prevent the tea leaves from overflowing along the through hole.

[0013] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. The tea fermentation device for tea processing uses a turning rod that can move up and down and rotate on its own in the turning mechanism. Combined with the moving mechanism, the entire turning mechanism is driven to move back and forth laterally along the box. This makes the turning action not limited to the same plane and position. The turning rod can turn and flip the tea at different depths and horizontal positions in the fermentation box, effectively breaking the static accumulation of tea leaves. This greatly improves the uniformity of contact between tea leaves and air, avoids the problem of over-fermentation or under-fermentation in some areas, and thus significantly improves the overall fermentation quality and consistency.

[0014] 2. The tea fermentation device for tea processing uses a hinged lever to drive an arc-shaped plate to move against the inner wall of the fermentation box. While turning the tea, it can continuously scrape off the tea residue attached to the inner wall, preventing the tea from sticking to the box wall for a long time, accumulating, or even deteriorating. This reduces the frequency and workload of cleaning and maintenance, helps to maintain a clean and stable fermentation environment inside the fermentation box, and ensures that the tea fermentation process is not adversely affected by residues.

[0015] 3. The tea fermentation device for tea processing features arc-shaped gathering plates on both sides of the fermentation chamber. These plates guide and gather the tea leaves in the central area of ​​the chamber when the tea is turned and shaken, effectively preventing the tea leaves from accumulating in the corners and forming fermentation dead zones. At the same time, the U-shaped arc rods at the through holes and the bristles on their inner sides form a flexible sealing barrier, which effectively blocks the tea leaves during turning and shaking, preventing them from overflowing from the fermentation chamber through the through holes of the moving mechanism. This ensures the sealing of the fermentation space and improves the safety and reliability of the equipment operation. Attached Figure Description

The arc plate 37 is set in accordance with the movement trajectory of the turning rods 36 and is hinged to the turning rods 36, so that the turning rods 36 drive the arc plate 37 to flip when rotating, thereby scraping off the tea residue attached to the inner wall surface of the fermentation box 1 while turning the tea leaves. A moving mechanism 4 is provided on one side of the outer wall of the fermentation box 1. The moving mechanism 4 is used to drive the turning mechanism 3 to move its position inside the fermentation box 1. The moving mechanism 4 includes a track 41 fixedly connected to the outer wall of the fermentation box 1. The track 41 is arranged in the transverse direction along the through hole 31 of the fermentation box 1. A slider 42 is slidably connected to the track 41.

Springs 49 are sleeved on the outer walls of the two L-shaped rods 43 to push the slider 33 down and abut against the arc groove 32, so that the rotating shaft 34 can move up and down. The L-shaped sliding sleeves 44 move down, causing the mounting block 45 to move down, and pushing the mounting block 45 fixedly connected between the two L-shaped sliding sleeves 44. The mounting block 45 is rotatably connected to one end of the rotating shaft 34, so that the movement of the slider 42 can drive the rotating shaft 34 to move as a whole. A gear 46 is fixedly sleeved on the outer wall of the rotating shaft 34. A rack 47 corresponding to the gear 46 is provided on the outer wall of the fermentation tank 1. The gear 46 and the rack 47 mesh with each other to convert the rotational motion of the rotating shaft 34 into linear movement along the direction of the track 41. A movable rod 48 is fixedly connected to one end of the two L-shaped sliding sleeves 44 away from the L-shaped rod 43. The movable rod 48 slides in the groove opened on the front of the rack 47.

Inside the fermentation box 1, a shaking mechanism 5 is also provided. The shaking mechanism 5 is used to disperse the tea leaves during the turning process. The shaking mechanism 5 includes a separation plate 51. The separation plate 51 is slidably connected in a rectangular through hole opened at the bottom of the fermentation box 1. Four corners of the bottom of the separation plate 51 are fixedly connected with push rods 52. The bottom of the push rods 52 is fixedly connected with rectangular sliders 53. Inside the fermentation box 1, a partition plate is provided, and two side plates are fixedly connected inside the partition plate. And the separation plate 51 is located inside the side plates and slides. A plurality of limiting columns 54 are fixedly connected between the bottom of the inner wall of the fermentation box 1 and the partition plate. The rectangular sliders 53 are slidably connected to the outer wall of the limiting columns 54. A second spring 55 is sleeved on the outer wall of the limiting columns 54, which is used to provide a reset elastic force after the push rods 52 are stressed. Below the side plate, an installation groove is provided, and the rectangular sliders 53 are located inside the installation groove and slide. Among them, a first baffle 56 and a second baffle 57 are provided inside the installation groove. The first baffle 56 is connected below the rectangular slider 53. The second baffle 57 is fixedly connected to the bottom of the inner wall of the fermentation box 1. The first baffle 56 and the second baffle 57 are in contact with each other, which is used to block and isolate the installation groove. Inside the fermentation box 1, two arc-shaped gathering plates 6 and arc-shaped rods 7 are also provided. The two arc-shaped gathering plates 6 are respectively arranged on both sides of the inner wall of the fermentation box 1, which are used to guide the tea leaves during the turning and shaking processes, so as to concentrate the tea leaves towards the middle area of the fermentation box 1 and prevent the tea leaves from accumulating in the corner areas of the box body. The arc-shaped rod 7 is in a shape of a Chinese character 'hui'. And a hair blocking member 8 is provided on the inner wall of the 'hui'-shaped arc-shaped rod 7. The hair blocking member 8 is used to block the tea leaves during the turning and shaking processes of the tea leaves, so as to prevent the tea leaves from overflowing along the through hole 31.

[0020] Working principle: When in use, first put the tea leaves to be fermented into the inside of the fermentation box 1. The fermentation box 1 provides a relatively closed fermentation space for the tea leaves. The supporting legs 2 are used to support the fermentation box 1 to keep it stable during the working process. During the tea leaf fermentation process, start the motor 413. The output end of the motor 413 drives the rotating shaft 34 to rotate around its own axis. When the rotating shaft 34 rotates, the fixed sleeve 35 fixedly sleeved on its outer wall rotates synchronously. A plurality of turning rods 36 equidistantly arranged on the outer wall of the fixed sleeve 35 make circular motions around the rotating shaft 34, so as to stir and turn the tea leaves inside the fermentation box 1, making the tea leaves continuously loose and avoiding local accumulation. During the rotation of the turning rods 36, since the turning rods 36 are hinged to the arc-shaped plates 37, the turning rods 36 will drive the arc-shaped plates 37 to rotate synchronously when rotating, so that the arc-shaped plates 37 move along the surface of the inner wall of the fermentation box 1, thereby scraping the tea leaf residues attached to the inner wall of the fermentation box 1, reducing the accumulation of tea leaf residues and keeping the fermentation environment clean. At the same time, both ends of the rotating shaft 34 cooperate with the arc-shaped grooves 32 in the through hole 31 through the sliders 33, so that the rotating shaft 34 can move up and down along the trajectory of the arc-shaped grooves 32 during the rotation process, thereby changing the turning height of the turning rods 36 inside the fermentation box 1 and improving the coverage range of the tea leaf turning. While the rotating shaft 34 continues to rotate, the gear 46 fixedly sleeved on the outer wall of the rotating shaft 34 meshes with the rack 47 fixedly installed on the outer wall of the fermentation tank 1, converting the rotational motion of the rotating shaft 34 into linear movement along the track 41. This drives the entire turning mechanism 3 to reciprocate along the through hole 31 inside the fermentation tank 1. During the movement of the turning mechanism 3, the slider 42 on the track 41 moves synchronously. The slider 42 drives the mounting block 45 to move as a whole through the L-shaped rod 43 and the L-shaped sliding sleeve 44, so that the rotating shaft 34 does not move inside the fermentation tank 1. The tea leaves are turned over at the same position to avoid insufficient turning in a local area for a long time, thus improving the overall fermentation uniformity. At the same time, spring 49 is sleeved on the outer wall of L-shaped rod 43, which provides continuous downward elastic force to slider 33 during the movement of the turning mechanism 3, so that slider 33 always abuts against arc groove 32 and through hole 31, ensuring the stability of the vertical movement of rotating shaft 34. Meanwhile, tension spring 412 provides tension to rack 47, so that rack 47 always maintains meshing with gear 46, ensuring the continuity and reliability of the movement process of turning mechanism 3. While the turning mechanism 3 turns the tea leaves, the shaking mechanism 5 inside the fermentation box 1 works simultaneously. When the turning rod 36 moves the tea leaves, the tea leaves exert a squeezing effect on the separating plate 51, causing the separating plate 51 to slide up and down in the rectangular through hole at the bottom of the fermentation box 1. The push rod 52, which is fixedly connected to the bottom of the separating plate 51, moves accordingly. The push rod 52 drives the rectangular slider 53 at its bottom to slide along the outer wall of the limiting post 54 and compress the second spring 55. When the external force decreases, the second spring 55 releases its elasticity, pushing the rectangular slider 53 and the push rod 52 to reset, causing the separating plate 51 to vibrate back and forth, thereby shaking the tea leaves piled up at the bottom of the fermentation box 1, making the tea leaves more loose during the turning process, and further improving the uniformity of oxygenation of the tea leaves. The baffle 1 56 and the baffle 2 57 are set in close contact to form a barrier for the installation groove, preventing the tea leaves from entering the installation groove and ensuring the stability of the movement of the shaking mechanism 5. During the operation of the turning mechanism 3 and the shaking mechanism 5, the arc-shaped gathering plates 6 set on both sides of the inner wall of the fermentation box 1 guide and gather the tea leaves, causing the tea leaves that are turned and shaken to gradually concentrate in the central area of ​​the fermentation box 1, preventing the tea leaves from accumulating in the corners of the box. At the same time, the arc-shaped rod 7 with a U-shape and the bristle 8 set on its inner wall block the position of the through hole 31, preventing the tea leaves from moving towards the through hole 31 during the turning process, preventing the tea leaves from overflowing the fermentation box 1 along the through hole 31, and improving the stability and safety of the device during use.

Many methods and approaches exist for implementing this technical solution; the above description is merely a preferred embodiment of the invention.
