After drying, tea must be sorted and graded to produce the commercially specified leaf grades required by buyers and the bulk tea market. Tea sorting equipment includes: vibrating flat screens and rotary screens (sort by particle size — separating larger leaf grades from finer grades, dust, and broken particles); fibre extractors (remove light stem fibres and stalks from the tea — fibre reduces quality and is penalised in grading); stalk extractors (specifically target the coarser, denser stalks that remain after rolling and firing — their presence reduces the quality grade); optical colour sorters (inspect individual tea particles by colour and reflectance, detecting and removing off-colour particles — pale yellow particles from unfermented material, black particles from burnt leaf, or foreign material; standard in premium orthodox tea grading and in specialty or export-grade CTC tea); and dust and fine sifters (remove the finest particles below the minimum marketable size — the tea dust and fanning grades are separately packed for specific markets including mass-market tea bags).
Frequently asked questions
What are the standard international tea grades?
Tea grades are defined by the International Tea Committee and used in auction and export trade. Orthodox black tea grades include (from largest to smallest leaf): OP (Orange Pekoe) — whole rolled leaf; BOP (Broken Orange Pekoe) — broken leaf; BOPF (Broken Orange Pekoe Fannings) — finer broken leaf; D (Dust) — fine particles used for fast-brew bags. CTC grades are described differently: BP (Broken Pekoe), PD (Pekoe Dust), D (Dust). Green tea has different grading terminology (Gunpowder, Young Hyson, Chun Mee, etc.) based on rolling style and leaf appearance. The sorting machinery configuration produces different grades as separate outputs and must be designed for the specific grades your buyers require.
Do I need an optical colour sorter for tea processing?
An optical colour sorter is not essential for all tea processing operations — its justification depends on the target market and the quality premium available. For commodity bulk CTC tea sold at auction, screen sorting and fibre extraction are the primary sorting steps. For premium orthodox tea sold to branded tea companies or direct-to-consumer, an optical colour sorter can significantly improve the appearance and cup uniformity of the finished grade by removing off-colour particles. For export markets with strict quality specifications or food safety requirements (aflatoxin-contaminated material often has visual colour changes), colour sorting provides additional assurance. Evaluate whether the quality improvement justifies the capital cost for your specific market and product.
