NFM color sorting machine by TOMRA

The NFM field color sorting machine is a robust and reliable harvester mounted sorter which performs effective color and foreign material sorting.

The NFM sorting machines are high performance machines that are simple to operate with low running costs. The NFM provides excellent sorting, even in the most difficult environments with dirt, dust and vibration. These field sorters can deal with hot, cold and wet weather while maintaining the quality of the harvest.


By automating its tomato processing lines with TOMRA’s NFM field sorting machines, Serkka Farms was able to increase its output enormously and watch labor cost drop dramatically. Read their story.

In-plant & harvester sorting

Key features

Sensor Technology

The produce is spread uniformly on to the infeed belt and is scanned in free fall by a camera positioned at the end of the conveyor belt. A few milliseconds later one type of material will be rejected by intelligent finger ejectors, while the good produce continues its way along the harvester.

Product Benefits

  • Significant labor reduction
  • Increased throughput
  • Increased yield
  • Proven technology for better quality sorting

Advanced Sorting Criteria

The NFM can sort multiple food applications by the following sorting criteria:

  • Size
  • Color
  • Defect
  • Foreign materials/objects
