[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0017] Example

[0018] Referring to Figure 1, an embodiment of this utility model provides a continuous kneading and shaping tea processing device. The device includes: a working cylinder 1, a discharge sieve cylinder 2 coaxially connected inside the working cylinder 1, and a kneading component connected inside the discharge sieve cylinder 2. The kneading component includes a temperature controller and a multi-layer kneading disc assembly, the outer circle of which has protrusions and grooves.

[0019] It should be noted that the tea processing device provided in this embodiment of the invention includes a working cylinder 1, a discharge sieve cylinder 2, a temperature controller, and a multi-layer kneading disc assembly. During tea processing, the temperature controller, the multi-layer kneading disc assembly, the discharge sieve cylinder 2, and the working cylinder 1 are installed sequentially. Tea leaves are placed into different multi-layer kneading disc assemblies, and then the multi-layer kneading disc assemblies are rotated. The tea leaves are kneaded through the meshing and squeezing between the protrusions and grooves. During the kneading process, the temperature is monitored and controlled in real time by the temperature controller to ensure that the tea leaves maintain their appropriate quality and shape at a suitable temperature. Specifically, high temperature aids shaping, while low temperature inhibits enzyme activity, preventing excessive oxidation that could affect color and aroma. Optionally, the working cylinder 1 and the discharge sieve cylinder 2 are coaxially connected. This design facilitates equipment maintenance and cleaning, and allows for the replacement of different specifications of the discharge sieve cylinder 2 according to the processing needs of different types of tea. The inner wall of the discharge sieve cylinder 2 is polished to reduce frictional resistance and improve the flowability of the tea leaves within the cylinder. The multi-layer kneading disc assembly can achieve simultaneous or individual multi-layer kneading, and can also achieve multi-stage kneading of tea leaves, thereby enabling the processing of various types of tea leaves. This solves the problems of unstable tea leaf kneading and shaping effects and limited application range in existing technologies.

[0020] Furthermore, the multi-layer kneading disc assembly includes at least a first kneading disc assembly 3 and a second kneading disc assembly 4 arranged in parallel and at intervals. Both the first kneading disc assembly 3 and the second kneading disc assembly 4 contain kneading discs 5. The first kneading disc assembly 3 contains two interlocking kneading discs 5, and the second kneading disc assembly 4 contains four interlocking kneading discs 5. Figure 1 is a cross-sectional view of the structure of this application, showing the arrangement of the kneading discs 5. This arrangement ensures that the tea leaves receive uniform force during kneading, avoiding localized over- or under-pressure, while simultaneously achieving the propulsion, crushing, and shaping of the tea leaves.

[0021] Furthermore, both the protrusions and grooves are spiral-shaped, and the spiral directions of two adjacent kneading discs 5 are opposite. The spiral protrusions and grooves effectively increase the contact area between the kneading discs 5 and the tea leaves, further enhancing the kneading effect.

[0022] Furthermore, both the first kneading disc group 3 and the second kneading disc group 4 are connected to an isolation box 6 at their bottom, with the outer circle of the isolation box 6 in contact with the inner wall of the discharge sieve cylinder 2. The contact between the outer circle of the isolation box 6 and the inner wall of the discharge sieve cylinder 2 serves to provide support and isolation, preventing leakage of tea leaves during the kneading process.

[0023] Optionally, the isolation box 6 has a through hole 10, through which the upper layer of tea leaves can enter the lower layer for further kneading. Layered pressure ensures even stress distribution throughout the tea leaves, reducing over-kneading and under-kneading, improving kneading efficiency, and shortening processing time. This multi-stage kneading process is suitable for various tea types; for example, light pressure on tender leaves preserves their integrity, while heavier pressure on coarse, older leaves promotes pectin extraction. It also allows for flexible control of oxidation levels, making it suitable for green tea, oolong tea, and pu-erh tea, resulting in a more tightly rolled and uniform tea leaf. A sealing cap is electrically connected to the through hole 10, and its opening and closing are controlled electronically.

[0024] Furthermore, the discharge screen cylinder 2 is provided with a first discharge hole group 7 and a second discharge hole group 8. The diameter of the first discharge hole group 7 is larger than that of the second discharge hole group 8, and the first discharge hole group 7 is located above the second discharge hole group 8. Through the above-mentioned design of the graded discharge hole group, tea leaves of different specifications can be automatically graded and discharged after kneading, thereby reducing the workload of subsequent screening processes. In addition, the diameter of tea particles usually gradually decreases as the kneading time increases. Through the discharge hole groups with different diameters, the production and discharge of tea leaves of different qualities can be realized. Specifically, the first discharge hole group 7 is located above the first kneading disc group 3, and the second discharge hole group 8 is located above the second kneading disc group 4. It should be noted that after the tea leaves are kneaded into granules, they can be blown up by the wind and extended into the air outlet pipe of the discharge screen cylinder 2, blowing the air outlet of the air outlet pipe out of the discharge screen cylinder 2. Alternatively, air can be blown into the discharge screen cylinder 2 from the outside, so that the tea leaves can be blown out of the discharge screen cylinder 2 through the first discharge hole group 7 or the second discharge hole group 8 and enter the working cylinder 1.

[0025] Furthermore, the temperature controller includes a temperature sensor connected to the kneading disc 5 and a circulating cooling pipe connected inside the isolation box 6, which is connected to an external cooling system. The temperature sensor connected to the kneading disc 5 is used to monitor the temperature changes of the tea leaves in real time during the kneading process and feed the data back to the control system. The circulating cooling pipe is located inside the isolation box 6 and connected to the external cooling system to regulate the temperature during the kneading process. When the temperature is detected to be too high, the control system activates the circulating cooling pipe, and the cooling medium flows evenly through the circulating cooling pipe to cool the kneading disc 5 and its surrounding area, ensuring that the temperature during the kneading process is always maintained within a suitable range. When the temperature is detected to be too low, the control system stops the operation of the circulating cooling pipe to avoid over-cooling and affecting the quality of the tea leaves. The circulating cooling pipe is arranged evenly along the circumference of the isolation box 6 to ensure that the cooling medium can flow evenly inside the isolation box 6, thereby achieving precise temperature control of the kneading disc 5 and its surrounding area. The introduction of the temperature controller enables precise temperature control during the kneading process, avoiding a decline in tea quality due to excessively high or low temperatures, and further improving processing quality.

[0026] Furthermore, multiple drivers are connected inside the isolation box 6. The output ends of the drivers are connected to the kneading discs 5 to provide rotational power to the kneading discs 5. The number and position of the drivers are configured according to the number and arrangement of the kneading discs 5 to ensure that each kneading disc 5 can operate independently and maintain synchronization. The arrangement of the drivers in this embodiment not only improves the operating efficiency of the kneading discs 5, but also enhances the overall stability of the equipment.

[0027] Furthermore, the working cylinder 1 and the discharge screen cylinder 2 are detachably connected, allowing the working cylinder 1, which receives tea leaves, to be easily removed, and also making the cleaning and maintenance of the equipment more convenient. Specifically, the connection is either threaded or snap-fit. After prolonged use, the user can easily disassemble the discharge screen cylinder 2 for thorough cleaning, preventing residual tea leaves from affecting the quality of the next processing. This design also allows users to replace the discharge screen cylinder 2 with different specifications according to different types of tea, thereby expanding the application range of the equipment. In addition, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
