The Sunkist® CAB-G2 Grading Unit is a high speed, high-resolution electro-mechanical computer vision system. The computer vision system analyzes the complete surface of the fresh citrus fruit for a variety of quality attributes. These attributes include:

  • Blemish (Defect) - light, medium, dark & total scar
  • Color - average color, darkest green, or lightest color, peak color, variegation
  • Size - average diameter, characteristic diameter or volume
  • Shape - Aspect ratio and roundness
  • Weight - 4-point weighing

All functions use nominal values for setting break points that are determined by running test fruit and adjusting these values accordingly.
