Abstract
Description
Technical Field
[0001] This utility model relates to a green tea fixation roller, specifically a rotary green tea fixation roller, belonging to the field of green tea fixation technology. Background Technology
[0002] The fixation process for green tea is a key technique that uses high temperatures to destroy the enzyme activity in fresh tea leaves, prevent the oxidation of tea polyphenols, remove some moisture, and dissipate the grassy smell. It lays the foundation for the clear soup and green leaves of green tea. Rotary green tea fixation rollers are used when green tea processing needs to achieve continuous operation to improve efficiency, or to ensure that the tea leaves are heated more evenly and to avoid local scorching, especially when processing batches of fresh leaves in medium and large-sized tea processing plants.
[0003] The existing utility model patent with authorization announcement number CN218999440U discloses a rotary green tea fixing roller. By designing the roller, multiple mounting grooves are opened inside the roller, and rollers are movably mounted inside the mounting grooves. A rotating shaft is rotatably connected inside the roller, and a spiral blade is fixedly connected to the rotating shaft. This divides the originally large-diameter roller body into multiple smaller-diameter rollers, thereby reducing the amount of tea leaves inside the rollers, increasing the degree of tumbling of the green tea leaves, thus increasing the heat exchange rate, making the green tea leaves fixation more uniform, and increasing the fixing efficiency. Through the design of the housing, and the interaction between the first and second rotating blades, the force of the torsion spring on the second rotating blade is greater than... The force of the torsion spring acting on the first rotating plate causes the second rotating plate at the bottom of the box to press against the first rotating plate inside the groove. This creates a gap between the first rotating plate and the groove, through which the green tea leaves inside the box enter the drum. The leaves are then conveyed from one end of the roller to the other along the spiral blades. During this conveying process, the green tea leaves are tumbled and heat-exchanged. This process ensures that the amount of green tea leaves in each drum is consistent, thereby increasing the heat exchange rate inside the drum, making it heat evenly, and ensuring a uniform degree of processing. This process also helps to thoroughly release the grassy aroma of the green tea leaves.
[0004] While the aforementioned technical solutions can improve the efficiency of tea processing to some extent, their structural design makes cleaning extremely difficult and lacks a convenient cleaning structure. This leads to prolonged accumulation of tea residue, which significantly reduces the effectiveness of subsequent processing. Therefore, a rotary green tea processing roller is proposed here.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.
[0027] Please see Figures 1-5 This utility model provides a rotary green tea fixing roller, including a U-shaped base 1. A support block 2 and two auxiliary wheels 6 are fixedly connected to the upper surface of the U-shaped base 1. A turning roller 3 is arranged above the U-shaped base 1. The hollow structure in the middle of the U-shaped base 1 facilitates the heating of the turning roller 3 by a heat source below, thereby facilitating the fixing of the green tea inside the turning roller 3. Multiple obstructing strips are present inside the turning roller 3 to ensure uniform heating and fixing of the green tea. A drive motor 4 is fixedly connected to the inner wall of the support block 2. The output end of the drive motor 4 and the end of the turning roller 3 near the support block 2 are jointly fixedly connected to a rotating... An auxiliary ring 7 is fixedly connected to the outer surface of the column 5 and the turning roller 3. A convenient cleaning mechanism 8 is provided on the outer side of the turning roller 3. The convenient cleaning mechanism 8 includes a bracket 801. A support rod 802 is fixedly connected to the right side of the bracket 801. The inner wall of each auxiliary wheel 6 is in contact with the outer surface of the auxiliary ring 7. Four support columns 9 are fixedly connected to the bottom surface of the U-shaped seat 1. A support plate 10 is fixedly connected to the bottom end of each support column 9. The support column 9 raises the overall height of the equipment, making it easier to place the heating device below. The support plate 10 increases the contact area with the ground, lowers the center of gravity of the equipment, prevents the equipment from tipping over, and improves the overall stability.
[0028] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3The bottom end of the support rod 802 is fixedly connected to a counterweight 803. The inside of the turning roller 3 is provided with an assembly plate 808. The outer surface of the output end of the drive motor 4 is fixedly connected to a coupling 20. The inner wall of the coupling 20 is fixedly connected to the outer surface of the rotating column 5. The coupling 20 can buffer the vibration when the output end of the drive motor 4 is connected to the rotating column 5, reduce component wear, and at the same time ensure the stability and accuracy of power transmission, avoid unstable rotation speed of the turning roller 3 due to connection deviation, and ensure the blanching effect.
[0029] Please refer to this carefully. Figure 1 , Figure 4 and Figure 5 A connecting frame 809 is fixedly connected to the right side of the assembly plate 808. A drainage tube 810 is provided inside the connecting frame 809. The outer surface of the drainage tube 810 is fixedly connected to the inner wall of the assembly plate 808. A first anti-slip sleeve 13 is fixedly connected to the outer surface of the support rod 802. Several identical first anti-slip protrusions 14 are fixedly connected to the outer surface of the first anti-slip sleeve 13. The first anti-slip sleeve 13 and the first anti-slip protrusions 14 increase the friction between the hand and the support rod 802, making it easier for the operator to adjust the position of the support rod 802, avoiding hand slippage, and improving the safety and convenience of operation.
[0030] Please refer to this carefully. Figure 1 , Figure 4 and Figure 5 The outer surface of the drainage pipe 810 is fixedly connected to several identical nozzles 811. The outer surface of each nozzle 811 is fixedly connected to the inner wall of the connecting frame 809. A hard brush 812 is fixedly connected to the right side of the connecting frame 809. An assembly ring 11 is fixedly connected to the outer surface of the counterweight 803. Several identical assembly holes 12 are opened on the upper surface of the assembly ring 11. The assembly ring 11 and the assembly holes 12 facilitate the fixing of the counterweight 803 to the ground or other base, enhance the fixing effect of the counterweight 803, prevent the convenient cleaning mechanism 8 from shifting during operation, and ensure the stable operation of the cleaning work.
[0031] Please refer to this carefully. Figure 1 and Figure 3 The inner wall of the bracket 801 is fixedly connected to two support cylinders 804. Each support cylinder 804 is slidably connected to a guide rod 805. The left end of each guide rod 805 is in contact with the right side of the assembly plate 808. The bracket 801 is provided with a top plate 15. The inner wall of the top plate 15 is fixedly connected to an auxiliary bearing 16.
[0032] Please refer to this carefully. Figure 1 and Figure 3Each support cylinder 804 is equipped with a return spring 807 inside. The two ends of each return spring 807 are in contact with the inner wall of the support cylinder 804 and the right end of the guide rod 805, respectively. The inner wall of the bracket 801 is threaded with a hand-tightened threaded rod 17. The outer surface of the hand-tightened threaded rod 17 is fixedly connected to the inner ring of the auxiliary bearing 16. The auxiliary bearing 16 can reduce the friction between the hand-tightened threaded rod 17 and the top plate 15, making the rotation of the hand-tightened threaded rod 17 smoother. At the same time, it prevents the top plate 15 from rotating synchronously with the hand-tightened threaded rod 17, ensuring that subsequent adjustment operations can be carried out normally. By rotating the hand-tightened threaded rod 17, the top plate 15 can be moved, thereby adjusting the position of the guide rod 805 and the limit pin 806, which facilitates the adjustment of the fit between the hard brush 812 and the inner wall of the turning roller 3, adapting to hard brushes 812 with different wear levels, and improving the cleaning effect.
[0033] Please refer to this carefully. Figure 3 Each guide rod 805 has a fixed limit pin 806 at its left end. The outer surface of each limit pin 806 is in contact with the inner wall of the assembly plate 808. The outer surface of the hand-tightening threaded rod 17 is fixedly connected to a second anti-slip sleeve 18. The outer surface of the second anti-slip sleeve 18 is fixedly connected to several identical second anti-slip protrusions 19. The second anti-slip sleeve 18 and the second anti-slip protrusions 19 increase the friction between the hand and the hand-tightening threaded rod 17, making it easier for the operator to rotate the hand-tightening threaded rod 17, avoiding slippage, and improving the convenience of adjustment operation.
[0034] In use, the following steps are taken: First, fresh tea leaves are placed inside the turning drum 3. Then, the drive motor 4 is started. The drive motor 4 drives the rotating column 5 to rotate through the coupling 20. The rotating column 5 then drives the turning drum 3 to rotate. During the rotation of the turning drum 3, the auxiliary ring 7 on its outer surface contacts the auxiliary wheel 6 on the U-shaped seat 1. The auxiliary wheel 6 supports and limits the turning drum 3, preventing it from shifting and ensuring that the tea leaves are rolled evenly inside the turning drum 3. At the same time, a heating device is set below the turning drum 3 to use high temperature to destroy the enzyme activity in the tea leaves, thus completing the fixation process.
[0035] After the tea processing is completed, if it is necessary to clean the turning roller 3, the assembly plate 808 is placed inside the turning roller 3. The return spring 807 in the support cylinder 804 pushes the guide rod 805, causing the limiting pin 806 at the left end of the guide rod 805 to engage with the inner wall of the assembly plate 808, thus fixing the assembly plate 808. Next, the external water supply equipment is connected to the diversion pipe 810, and water flows through the diversion pipe 810 and sprays out from the nozzle 811. At the same time, the drive motor 4 is started again to drive the turning roller 3 to rotate slowly. The inner wall of the turning roller 3 contacts the hard brush 812 on the connecting frame 809, and the hard brush 812 scrubs the tea residue on the inner wall, thus cleaning the turning roller 3.
[0036] If it is necessary to adjust the fit between the hard bristle brush 812 and the inner wall of the turning roller 3, rotate the hand-tightening threaded rod 17. With the cooperation of the auxiliary bearing 16, the hand-tightening threaded rod 17 pushes the top plate 15. The top plate 15 presses the guide rod 805. The guide rod 805 drives the limit pin 806 to adjust the position of the assembly plate 808, thereby changing the fit of the hard bristle brush 812 to ensure the cleaning effect. After cleaning, rotate the hand-tightening threaded rod 17 in the opposite direction. The return spring 807 returns to its original position, and the assembly plate 808 can be removed for maintenance or storage. The design of the entire rotary green tea fixing roller effectively solves the problem that the lack of a convenient cleaning structure that can improve the convenience of cleaning leads to the long-term accumulation of tea residue, which greatly reduces the subsequent fixing effect.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
