Tea Colour Separator

Tea Quality Grading and Color Separation System



  • Tea grading according to color in low-grown area tea estates/factories.
  • This is very much necessary for factories producing tea for auctions in the international market, whose concern is mostly on the appearance of the tea samples.
  • For factories concerned with low investment for this kind of machine rather than imported ones (Imported price Rs. 10M – 20M).


  • High-resolution CCD camera for color detection
  • High-speed FPGA based electronics for processing
  • Mechanical system with high-speed valves and stainless steel channels

Technical Description

The machine operates on the principle of identifying different types of tea particles based on color and separating them by activating a pneumatic actuator system. The system captures images of moving tea particles through a Charged Coupled Device (CCD) high-speed camera and processes that image data using Field Programmable Gate Array (FPGA) and advanced electronic systems.
