nfm sorting machine by tomra

The NFM field 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, simple to operate and have low running costs. The NFM provides excellent sorting, even in the most challenging environments with dirt, dust, and vibrations. These field sorters can deal with hot, cold, and wet weather while maintaining the harvest quality.


By automating its tomato processing lines with TOMRA NFM field sorting machines, Serkka Farms increased its output enormously and watched labor costs drop dramatically. Read their story >

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
