Description

Technical Field

[0001] The invention relates to the field of green tea processing, in particular to a green tea finishing rolling and cutting machine. Background Art

[0002] Green tea finishing is a key link in optimizing the quality and functionality of tea through specific processes. Its core benefits include improving tea stability, enhancing the release efficiency of effective ingredients, and expanding application scenarios. During the finishing process, green tea needs to go through basic processes such as withering, rolling, and drying. As an important step in finishing, chopping mainly acts on physical structure changes: mechanical force destroys the cell wall of tea leaves, making internal active substances such as tea polyphenols, catechins, amino acids, etc. easier to dissolve, thereby increasing the leaching rate and total amount of nutrients during brewing, which is especially suitable for the development of instant tea products in fast-paced consumption scenarios. The chopping process can also standardize the morphology of tea leaves, facilitate mechanized packaging and quality control, reduce production costs, and promote the processing efficiency of tea particles in subsequent deep processing (such as extraction and freeze-drying). Precise control of the degree of chopping during the finishing process can balance the flavor and functional release of tea leaves. For example, moderate chopping can not only retain the fresh aroma of green tea, but also enhance the bioavailability of antioxidant ingredients, while excessive chopping may lead to excessive precipitation of bitter substances. In addition, the surface area of ​​green tea increases after shredding, which is conducive to full contact with other raw materials in complex processing such as scenting and blending, laying a physical foundation for the development of functional tea products (such as tea powder and tea extracts). Fine processing also uses high-temperature instantaneous sterilization, vacuum packaging and other technologies, combined with the compact form after shredding, to extend the shelf life of green tea and reduce storage space. From an industrial perspective, the shredding process enables the high-value utilization of tea scraps, reduces resource waste, and meets the needs of sustainable development. Overall, the shredding operation in the fine processing of green tea is an important technical node connecting traditional tea making technology with the modern food industry. It achieves quality optimization, efficiency improvement and product innovation through physical modification to meet diversified market needs.

[0003] In order to facilitate the chopping of green tea, a green tea finishing rolling and cutting machine is designed in the prior art, such as the Chinese patent with application number CN202120035556.X. The present invention discloses a fully automatic green tea finishing rolling and cutting machine, including a housing, an upper end surface of the housing is provided with a feed hopper, a first rolling and cutting roller and a second rolling and cutting roller are provided inside the housing, an outer side wall of the housing is fixedly connected to a support platform, a driving motor is fixedly connected to the support platform, an output end of the driving motor is fixedly connected to a first rotating shaft, a first rolling and cutting roller and a first toothed disc are sleeved on the first rotating shaft, a second rotating shaft is rotatably connected to the inner side surface wall of the housing, a second rolling and cutting roller and a second toothed disc are sleeved on the second rotating shaft, and a discharge port is opened on the housing below the first rolling and cutting roller. In the present invention, the driving motor is started to drive the first rolling and cutting roller and the first toothed disc to rotate, and the rotation of the first toothed disc drives the rotation of the second toothed disc, thereby driving the second rolling and cutting roller to rotate synchronously with the first rolling and cutting roller, and the spiral cutter cooperates with each other, so that the whole device has a good chopping effect.

The screened green tea cannot be conveniently collected for re-processing, and the green tea is piled up under the machine body after processing. After opening the lifting door, the processed green tea needs to be collected manually, which affects the production efficiency.

The primary sieve plate 3 is only used to prevent large pieces of green tea raw material from falling directly into the secondary sieve plate, so the aperture of the primary sieve plate 3 is larger than the aperture of the secondary sieve plate. After the green tea is cut, since the primary sieve plate 3 is a downwardly concave arc plate, the green tea falls into the secondary sieve plate below under its own gravity and the vibrator 22 abutting under the primary sieve plate 3. The screening accuracy of the secondary sieve plate can be controlled by replacing plate bodies 7 of different specifications, and the plate body 7 can be quickly locked and installed or unlocked and removed through the fixed card block 13 on its periphery and the card slot 12 on the movable frame 6, so that the user can take out the screened green tea from the downward depression of the plate body 7, and the second sieve plate is located inside the barrel 1.

The weighing plate 8 can weigh the weight of the processed green tea and transmit the weight information to the controller. When the weight reaches the set standard, the vibrator 22 and the drive motor stop working, and the lifting cylinder 24 contracts to drive the lifting door to open. After the lifting door reaches the top, the in-position sensor of the lifting cylinder 24 is triggered. After receiving the in-position signal of the lifting cylinder 24, the controller starts the pushing cylinder 23. The pushing cylinder 23 enables the pushing plate 10 to push the green tea out of the lifting door. The lifting door can be connected to other logistics lines outside to make the production process smoother and more efficient, or a collection device can be directly placed to collect the green tea.
