Sunkist® CAB – G4.5 Ultimate Grading Technology

The Sunkist® CAB-G4.5 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, aspect ratio, roundness, variegation and canker identification.
  • Color – average color, darkest green, or lightest color, peak color.
  • Size – average diameter, characteristic diameter, or volume.
  • ‘Leader’ Sensor – DECAY (Clear Rot), Stem and Navel detection.
  • Weight – 4-point weighing
