Color Sorter – Grain and Seed Sorting

color sorter grain seed sorting

Color Sorter


Features dual view cabinets. Customized infrared light and camera assembly can be installed for special material. The latest 3 linear color CCD camera and FPGA processing system in addition to the high-speed electromagnetic ejector have been adopted in the machine, and also the multi-color touch screen has been installed therein, so it is a high-tech product combined with technology of optics, electronics and pneumatic NIR is an optional device. The machine can automatically reject contaminant or colored grains, featuring high sorting accuracy, great efficiency, simply operation, easy maintenance, compact structure and elegant appearance. The sorter is now in the leading position among the industry.

Advanced Vision System:

  • Specially designed optical to reduce shadow and distortion.
  • High speed, sensitive CCD camera with 2048 pixel resolution to detect tiny spot defects.
  • Optional NIR (Near Infrared) to detect foreign material with same color.

Intelligent software and Powerful Digital Image Processing:

  • 4th Generation FPGA + high speed DSP to deliver sorting algorithms.
  • Customized color model to support sophisticated defect processing including Spot, Area, Size defects.
  • Support multiple sorting modes to minimize product change over time.
  • Bi-chromatic (visible + NIR) sorting to support Light, Dark sort on both visible and NIR wavelengths, which cover all kinds of defects and foreign materials.

User Friendly Operation:

  • High resolution touch screen with user-friendly graphics.
  • Real time monitor of machine status.
  • Easy software upgrade with USB.

Optimized Ejection:

  • Fast valve response to ensure accurate ejection on defects.
  • Specially made ejectors and optimized timing for low carryover, reduced air consumption.
  • Dual air supply for stable air pressure under high defect sorting.
  • Optimized blow time to reduce good rice carried over into reject (R model).
