Description

Technical Field

[0001] This invention relates to the field of tea processing technology, specifically to a multi-machine linkage aroma tea color sorting, impurity removal and grading production line and its impurity removal and grading method. Background Technology

[0002] During the tea picking process, tea leaves often become mixed with impurities such as tea fruits and tea buds. During the initial and final processing, even more harmful impurities such as stones, plastics, metals, clods of earth, and cigarette butts can be introduced. For health and food safety reasons, it is necessary to remove these impurities, especially the harmful ones. The most common method for removing impurities from tea is manual sorting, which is labor-intensive and inefficient. Furthermore, due to individual differences among personnel, it is difficult to guarantee the consistent effectiveness of impurity removal.

[0003] With the widespread research, development, and use of color sorters in my country, many large and medium-sized tea enterprises now use them for impurity removal. This improves the efficiency and automation of tea impurity removal, reduces manual labor, and to a certain extent ensures the stability of impurity removal. Existing color sorters can solve the problems of labor-intensive, time-consuming, and ineffective tea refining and sorting operations, improving efficiency and quality while reducing costs. For high-quality green tea, the stem removal rate can reach over 95%, with a mis-picking rate of about 8%. Although this is still slightly lower than meticulous manual stem picking, the stem picking efficiency can reach over 300 kg / h, more than 300 times higher than manual stem picking, significantly improving labor productivity. However, existing technologies all use single color sorters, resulting in low output, which cannot meet the high-volume tea production requirements of large and medium-sized tea enterprises. Some tea enterprises have tried using multiple single color sorters simultaneously to solve the high-volume problem. However, this solution, because it only uses a single machine, requires coordinated production and a large investment of manpower, making it less cost-effective and failing to address the high-volume requirements and tea grading issues. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-machine linkage tea color sorting, impurity removal, and grading production line and its method. By setting up multiple color sorters and supporting conveyor connection equipment, and utilizing the interconnected communication between the control cabinets of each device, it can be operated with one button for multi-machine linkage or used individually, enabling flexible production and adaptable to varying tea production demands. Furthermore, due to its high level of automation, only necessary personnel are required at the combing machine and finished product packaging area; the remaining processing is automatically completed by intelligent equipment, saving labor and improving production efficiency and equipment utilization. In addition, the inclusion of a secondary color sorter allows for graded output of tea, enabling the separate sale of different grades and improving economic benefits. The impurity removal and grading efficiency is high, with a large processing capacity of up to 1000 kg / h, significantly improving labor productivity and effectively reducing tea production costs.
