Description

Technical Field

[0001] This application relates to the field of black tea processing, and in particular to a black tea processing screening device. Background Technology

[0002] Black tea, a fully fermented tea, is made from suitable new tea leaves through a series of processes including withering, rolling (or cutting), fermentation, and drying. During processing, black tea undergoes a chemical reaction centered on the enzymatic oxidation of tea polyphenols, resulting in significant changes to the chemical composition of the fresh leaves. Tea polyphenols decrease by more than 90%, while new components such as theaflavins and thearubigins are produced. Aroma compounds increase significantly compared to fresh leaves. Therefore, black tea is characterized by its red color, red liquor, red leaves, and sweet, mellow taste. After harvesting, black tea often contains many impurities, which reduce its quality. Therefore, these impurities need to be removed before processing.

[0003] The existing publication number CN217342294U discloses a screening device for black tea processing, including a base plate, a support column fixedly mounted on the top of the base plate, a baffle fixedly mounted on the support column, a compression spring mounted above the baffle, the compression spring sleeved on the support column, a pressure ring slidably mounted above the compression spring, a support frame fixedly mounted on the top of a positioning plate, a hydraulic cylinder fixedly mounted on the support frame, a push rod fixedly mounted at the output end of the hydraulic cylinder, and one end of the push rod passing through the positioning plate being fixedly connected to the corresponding crossbar. First, different types of black tea are placed in the corresponding sieve frames, and then the hydraulic cylinder is started. The hydraulic cylinder drives the push rod to move up and down reciprocally, and the push rod drives the crossbar to move up and down, thereby achieving the purpose of vibrating the sieve frame, so as to screen different types of tea at the same time. The screening efficiency is high. After continuous vibration, the tea is blocked in the sieve frame, while the impurity particles fall into the impurity collection box, which greatly reduces the cleaning burden of the staff.

[0004] In view of the above-mentioned existing technology, tea leaves are placed in a sieve frame and the sieve frame is moved up and down by the extension and retraction of a hydraulic cylinder to achieve sieving of tea leaves. Although the efficiency of sieving tea impurities is improved, the sieved tea leaves are blocked in the sieve frame. When taking out the tea leaves, it is necessary to pour out the tea leaves in the sieve frame one by one, which increases the workload of tea sieving and requires more labor costs. In order to solve the above problems, a black tea processing screening device is proposed.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0006] To address the aforementioned issues, this application provides a black tea processing and screening device.

[0007] The black tea processing and screening device provided in this application adopts the following technical solution:

A swinging component is provided on one side of the support to drive the multiple rotating frames to swing at the same time. Each rotating frame is rotatably provided with a sieve bucket for black tea screening and a rotating component to drive the sieve bucket to rotate.

[0009] Preferably, the swing assembly includes gear two, gear three, gear four, rack, and electric actuator. Gear two, gear three, and gear four all rotate on one side of the bracket and are respectively fixed to the ends of the plurality of rotating shafts away from the rotating frame. The rack slides on one side of the bracket, and the electric actuator is fixed on one side of the bracket. The telescopic end of the electric actuator is fixed to the rack, and the rack meshes with gear two, gear three, and gear four simultaneously.

Compared with related technologies, this not only helps to improve the screening efficiency and quality of tea, but also allows the swinging component to drive the sieve bucket to tilt after screening, so that the screened black tea can slide out naturally without the need for manual pouring out the tea leaves one by one in the sieve bucket, effectively reducing the workload after tea screening and lowering labor costs.

[0024] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0025] This application discloses a screening device for processing black tea. (See also...) Figure 1-6 A black tea processing and screening device includes a base 1. Two supports 2 are fixedly mounted on the top of the base 1. Multiple sets of connecting shafts 3 and rotating shafts 4 are rotatably mounted on the side of the two supports 2 that are close to each other. Rotating frames 5 are fixed at the ends of the multiple sets of connecting shafts 3 and rotating shafts 4 that are close to each other. A swing assembly is provided on one side of the support 2 to drive multiple rotating frames 5 to swing simultaneously. The swing assembly includes gear 2 11, gear 3 12, gear 4 13, rack 14, and electric push rod 15. Gear 2 11, gear 3 12, and gear 4 13 all rotate on one side of the support 2 and are fixed to the ends of the multiple rotating shafts 4 away from the rotating frames 5. The rack 14 slides on one side of the support 2. The electric push rod 15 is fixed on one side of the support 2. The telescopic end of the electric push rod 15 is fixed to the rack 14. The rack 14 meshes with gear 2 11, gear 3 12, and gear 4 13 at the same time. When the electric push rod 15 is activated, it pushes the rack 14 to slide back and forth, causing gear 2 11, gear 3 12, and gear 4 13 to rotate in both directions at the same time, thereby causing the corresponding rotating frames 5 to swing.

[0026] Each rotating frame 5 is equipped with a sieve 6 for screening black tea and a rotating assembly for driving the sieve 6 to rotate. The rotating assembly includes a gear ring 7, a motor 8, a gear 9, and a mounting frame 10. The gear ring 7 is fixed to the outside of the sieve 6, the mounting frame 10 is fixed to the top of the rotating frame 5, the gear 9 rotates on the top of the rotating frame 5, and the motor 8 is fixed to the top of the mounting frame 10. The rotor end of the motor 8 is fixed to the gear 9, and the gear ring 7 and the gear 9 mesh. When tea leaves are placed into the sieve 6, the motor 8 is started to rotate the gear 9, which in turn causes the gear ring 7 and the sieve 6 on it to rotate. In conjunction with the swing of the rotating frame 5, dynamic screening of black tea is achieved in the sieve 6, which helps to improve the screening efficiency and quality of tea leaves. After screening, the electric push rod 15 is started to tilt multiple sieve 6, which facilitates the natural discharge of the screened black tea leaves, reducing the workload after tea leaf screening.

[0027] Reference Figure 4 , 5 Multiple sieve hoppers 6 are equidistantly arranged along the vertical direction of the support 2. The sieve holes of each sieve hopper 6 gradually decrease in size from top to bottom, realizing multi-stage fine sieving of black tea. The uppermost sieve hopper 6 removes larger impurities and tea fragments. As the black tea moves downward, it passes through increasingly fine sieve holes, eventually obtaining high-quality black tea with uniform particle size. The bottom of the upper sieve hopper 6 extends into the lower sieve hopper 6 to avoid tea splashing during sieving. Each of the multiple sieve hoppers 6 has a discharge port 19 on one side. The length of each discharge port 19 gradually decreases from top to bottom, ensuring that black tea of ​​different particle sizes can automatically flow out from the corresponding discharge port 19, reducing subsequent manual sorting work and further reducing labor costs.

[0028] Reference Figure 1 , 6 The base 1 has a groove 18 on the top for the receiving box 16 to slide. The receiving box 16 is used to receive tea leaves. A handle 17 is provided on one side of the receiving box 16. Pulling the handle 17 makes the receiving box 16 slide along the length of the groove 18, which facilitates cleaning the tea leaves in the receiving box 16 and makes it easy to quickly replace or clean the receiving box 16.
