Sunkist®  CAB-G4 Blemish, Color, and Size Optical Grading System

The Sunkist®  CAB-G4 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.

  • The mechanical carrier is a patented spool / lifter / movable solenoid assembly unit that operates at a constant speed of 10 pockets per second per lane.
  • Multiple 2,4, 6 or 8 lane frames, up to 24 lanes, can be integrated and programmed to perform the functions of a single machine.
  • The system utilizes a Microsoft Windows®  platform for a fast/friendly operator interface, and elaborate reporting capabilities with over 20 reports to choose from.
  • Technical support utilizing PC Anywhere®  software, which allows for service support via modem line.
  • Custom reports using standard Crystal Reports®  data dictionary.
  • Sales Office PC possibility for exporting of data in Excel format.
  • Each lane is integrated with the multiple lane system.
  • Fruit can be sorted by Blemish, Color, Size, Variegation, and Long-Stem.
  • This information is transmitted to a host computer that allows an operator to interface with the system.
  • The operator chooses the various grading values to determine distribution of fruit on the multiple fruit drop points.
