Description

Technical Field

[0001] This utility model relates to the field of tea scattering machine technology, specifically a tea scattering machine for black tea production. Background Technology

[0002] Processing fresh tea leaves into finished tea requires multiple processing steps. After certain processing steps, fresh tea leaves need to undergo sun-drying, which involves exposing the tea leaves to sunlight to remove moisture and solidify the components within the tea. Furthermore, the quality of the sun-dried tea is closely related to the evenness with which the tea leaves are spread out during the sun-drying process.

[0003] In existing technologies, tea leaves are typically loosened manually and then scattered onto a drying area for spreading. However, manual loosening and scattering of tea leaves involves human contact, which can easily contaminate the leaves. Furthermore, manual scattering is unstable and cannot precisely control the uniformity of the spread, thus reducing tea quality and resulting in low production efficiency. Therefore, we propose a tea leaf scattering machine for black tea production. Utility Model Content

[0004] In view of the shortcomings of existing manual tea leaf spreading and scattering methods, which are prone to contamination due to human contact with the tea leaves and have poor stability, this utility model provides a tea leaf spreading machine for black tea production. It has the advantages of improving production efficiency, avoiding tea leaf contamination, and improving the quality of tea production, thus solving the problems mentioned in the background art.

A receiving box with an arc-shaped bottom is tightly attached to the bottom of the hopper, and a scattering box is connected to one side of the receiving box. The bottom of the scattering box has a trumpet-shaped structure. Support legs are symmetrically connected to the outer walls of both the hopper and the scattering box. A symmetrically arranged adjusting baffle is connected to the hopper through a third rotating shaft. The two adjusting baffles have an upward-facing V-shaped structure. One end of the third rotating shaft extends through to the outside of the hopper and is fixedly connected to a first motor. A fourth rotating shaft is rotatably connected inside the receiving box.

[0027] In summary, this tea leaf scattering machine for black tea production, when in use, has multiple rotating rollers 21 rotatably connected to the operating table 11 via a second rotating shaft 15. A conveyor belt 2 is connected to the outside of the rotating rollers 21, and a receiving tray 1 for receiving the material is placed on the conveyor belt 2.
