Working Principle of the Tea Colour Sorter Machine

A tea colour sorter machine is core equipment in tea processing that achieves efficient impurity removal and quality improvement.Using photoelectric recognition and intelligent sorting technology, it accurately removes impurities without damaging delicate tea buds.Below we explain its working principle in five core systems.

1. Feeding & Uniform Distribution System

The feeding system consists of a swing hopper, vibrating feeder, and chute.Tea materials first enter the vibrating feeder, where they are fully dispersed into a single, even layer on the chute.This stable, uniform flow enters the detection zone at a constant speed, reducing both misidentification and tea breakage, laying a solid foundation for high-precision sorting.

2. Photoelectric Detection System

As the “eyes” of the tea color sorter, the photoelectric system includes a stable light source, background plate, and high-resolution CCD lens.The lens captures colour, shape, and texture data from each tea leaf and converts light signals into electrical signals.The background plate acts as a reference for qualified tea, creating a clear contrast with stems, yellow leaves, and other impurities.

3. AI Intelligent Recognition System

The collected data is sent to the AI system, the “brain” of the tea sorting machine.Using deep-learning algorithms, the system compares real-time data with preset high-quality tea models, accurately identifying tea stems, discoloured leaves, broken leaves, and foreign materials.It is specially optimized for fragile tea to reduce mis-sorting and protect tea integrity.

4. Pneumatic Sorting System

Once impurities are detected, the control system activates high-speed air nozzles.These precise air jets gently blow impurities into the reject bin, while qualified tea continues into the good product bin.The nozzle design is specially calibrated for tea to ensure strong removal accuracy without damaging tender buds, making the tea color sorter machine ideal for high-grade tea processing.

5. Operation & Maintenance System

To ensure long-term stable performance, the machine is equipped with an automatic glass cleaning system and user-friendly touchscreen panel.The auto wiper keeps the lens dust-free, maintaining detection accuracy.Multiple built-in sorting modes allow quick adjustment for different tea types, making operation simple and efficient.
