What is tea sorting in tea processing?

Tea sorting is a crucial part of the tea production process, where foreign materials and inconsistencies are removed to ensure the quality and safety of the final product. As tea moves from raw leaves to finished products, various sorting technologies are employed to handle different impurities and defects. Techik provides advanced solutions for tea sorting, tackling both the common and more challenging impurities with innovative technology.

Tea Processing and Sorting Overview

1. Initial Sorting During Raw Tea Processing:
When fresh tea leaves are processed into raw tea, color sorters play a vital role in the initial removal of impurities. They effectively eliminate discolored leaves, tea stems, and larger foreign objects, addressing approximately 90% of the sorting challenges during this phase.

2. Remaining Challenges in Fine Tea Processing:
The remaining 10% of sorting issues often involve micro-impurities such as insect fragments, hair, and other tiny foreign materials. These are particularly difficult to manage in traditional tea processing and present a significant challenge for maintaining the quality of finely processed tea.

Techik’s Tea Sorting Solutions

To overcome these challenges, Techik offers a comprehensive solution that combines multiple technologies to address both the initial and more complex sorting tasks throughout tea production.

1. Raw Material Pre-Sorting:
Techik’s color sorting machines specialize in detecting and sorting out foreign objects, discolored leaves, and other visual defects. By utilizing visible light technology, these machines can differentiate between normal and irregular tea leaves, shapes, and impurities. This step effectively resolves 90% of sorting issues, ensuring the removal of the most prominent defects early in the production process.

2. Fine Processing Sorting:
For the remaining 10% of more subtle impurities, Techik’s Ultra-High-Definition Color Sorter steps in. This machine is equipped with advanced vision technology, capable of detecting micro-impurities like hair or small fragments that are difficult for the human eye to catch.
Additionally, Techik’s X-Ray Inspection Machine plays a critical role by utilizing density-based detection. X-Rays penetrate the tea leaves, identifying foreign objects that are invisible on the surface. This technology can detect both high-density objects, like stones, with a success rate of 99.99%, and lower-density materials, such as tiny fragments, with an accuracy of 99.5%.

3. Final Product Inspection:
As a final step before packaging, Techik’s machines ensure that any remaining impurities or defects are removed. The combined use of color sorting and X-Ray technology detects foreign objects, missing leaves, and defects, ensuring that the product meets the highest quality standards. Techik’s solutions can also assist in weight control by providing auxiliary support for weight inspection.

Techik’s Advanced Sorting Machines

1. Color Sorting Equipment:
Techik’s color sorters utilize visible light technology to identify surface differences in tea leaves. By scanning for color, shape, and surface irregularities, the machines efficiently sort out foreign materials and subpar leaves. However, these machines focus on external characteristics, so internal defects or color-similar impurities might escape detection. Techik’s Ultra-High-Definition Conveyor Color Sorter is especially adept at sorting micro-impurities such as hair, which can be hard to spot manually.

2. X-Ray Sorting Equipment:
Techik’s X-Ray machines provide a deeper level of detection by using X-Ray technology to penetrate the tea leaves and identify foreign objects based on density. These machines are capable of detecting a wide range of materials, from dense stones to fine low-density particles like small stones or fragments. The Techik Intelligent X-Ray Machine excels in sorting out foreign objects of various densities, ensuring superior quality control in tea production.

Techik’s sorting technology offers a comprehensive solution for tea processors, addressing both the common and complex challenges of tea sorting. By combining visible light-based color sorting and X-Ray density detection, Techik provides reliable, high-efficiency solutions that ensure a higher quality product. From raw material sorting to fine tea processing and final product inspection, Techik’s equipment delivers precise and dependable sorting that helps tea producers meet stringent market standards for safety, consistency, and quality.
