Key Role and Case Analysis of Color Sorter in Tea Export Processing
2025-08-27In tea export processing, meeting strict international quality standards is crucial, and Tea Color Sorter has become an indispensable core equipment—outperforming traditional manual sorting in efficiency and accuracy, and complementing other specialized Color Sorter models like Rice Color Sorter and Grain Color Sorter in the food processing chain.
The Tea Color Sorter plays three key roles: first, it removes impurities such as yellow leaves, stems, and stones from tea, ensuring the purity of exported tea. Its advanced Optical Sorter module uses high-resolution cameras and AI algorithms to identify even tiny color differences, achieving a sorting accuracy of over 99.7%. Second, it classifies tea by color and tenderness, which is essential for exporting high-value teas like Darjeeling or Matcha. The Color Sorting Machine can divide tea into multiple grades according to preset standards, meeting the customized needs of different markets. Third, it improves processing efficiency—an automatic Tea Color Sorter can handle 5-10 tons of tea per hour, far exceeding the 200-300 kg per day of manual sorting.
A typical case is a Chinese tea exporter supplying to the European market. Previously, their manual sorting often missed subtle yellow leaves, leading to 15% of shipments being returned. After adopting the Tea Color Sorter with multi-spectral detection, the return rate dropped to less than 1%. The machine also helped them classify green tea into three grades, increasing the average export price by 20%. Another case involves a Sri Lankan black tea processor: their Optical Sorter-equipped Color Sorting Machine efficiently removes tea dust and broken leaves, ensuring the tea meets the UK’s strict "whole leaf" standard, boosting their market share by 12% in one year.
Compared with Bean Color Sorter or Nut Color Sorter, the Tea Color Sorter has a more delicate sorting mechanism to avoid damaging fragile tea leaves. This design detail further confirms its irreplaceable role in tea export processing.
