Chunmee green tea is one of the most famous and best exported green teas of China. Its leaves are thin and arched like "eyebrows", so that it is known as "precious eyebrows" in China. The quality requirements are extremely high, as it is in high demand in the markets of North and West Africa, and Europe. It is a constant challenge for the tea processors and exporters to retain the uniform and needle shaped Chunmee curl and to remove the yellow flakes, dark stalks and other foreign matter. The traditional labor-intensive hand sorting or mechanical screening physically cannot meet the export requirements. Optical sorting chunmee green tea has become a new yardstick for exporter to securing high tea grading, high tea throughput, and best profitability in export.
The Difficulty of Chunmee Green Tea Processing
Chunmee has its own unique appeal involving its look and taste. But when harvesting, pan-firing and rolling, a few defects do get in the mix:
Mismatched Shapes: Broken leaves, flat pieces, and half-unfolded fragments disrupt the uniformity of the “eyebrow” look.
Discoloration: Yellow flakes, burnt leaves and brown stems may change the color and taste of the vibrant, green cup.
Impurities: Micro-impurities like hair, stone, thread, insect or dust is very strictly rejected by international import regulations (such as EU, FDA standards).
But Manual Inspection is NOT enough… It’s too slow, too expensive, and too prone to human error. That’s where advanced optical sorting can come in and change your production line.
How Optical Sorting Technology Changes Chunmee Green Tea Processing
Today, CCD and AI-based color sorters are likened to “superman eyes” which can detect thousands of tea leaves in a second. With optical sorting chunmee green tea methods incorporated in your plant, you will gain access to the latest generation of sorting technology:
1. Dual Color & Shape Recognition
Chunmee is however not just a matter of colour filtering, its unique arched shape needs to be retained. High end optical sorters are based on field proven CCD technology (Resolution up to 5340+ pixels) combined with intelligent AI algorithms which can detect not only based on colour but also on morphology. It then immediately identifies the:
The perfect curved eyebrow shape.
Flat, broken, or tiny pieces. .
Annoying yellow flakes and stalks.
2.Purging of the Brews to Remove Hidden Noise
The advanced sorters, equipped with multi-spectral or NIR (Near-Infrared) technology, are capable of detecting and removing non-tea items—such as pieces of plastic, string, insects, stones, etc.—that are of the same color as tea leaves but have different material density.
3. High processing traffics and low processing damage rate
Our highly sophisticated chute systems are engineered to float the rolled leaves over the sensors. High precision high speed jet solenoid valves ejectors jet a micro-pulse of compressed air High precision high speed jet solenoid valves ejectors when they spray a micro-pulse of compressed air can throw out the defected material smoothly and do not harm the surrounding material Chunmee sheets If not the soil is detected, a micro-pulse of compressed air is thrown to the soil which is directed to the reject chute.
