Description

Technical Field

[0001] The utility model relates to the field of tea production and processing, in particular to a tea processing production line. Background Art

[0002] Tea processing, also known as "tea making", is the process of making various semi-finished tea or finished tea by processing fresh tea leaves through various processing procedures. Usually, tea leaves need to go through multiple processing steps such as withering, killing green, rolling, etc. before they can become tea. According to different processing processes, it can be divided into primary processing, fine processing, reprocessing and deep processing. Different processing techniques form different types of tea, and the quality of each type of tea depends on the coordination of the processing procedures.

[0003] Patent document with patent number CN117481232A discloses a fully automatic tea processing production line, which includes a lower conveying mechanism, an upper conveying mechanism, a kneading mechanism, a liquid discharge mechanism, a feeding mechanism and a discharging mechanism.
