Key benefits

Exceptional ease of use

Our DR-M has new sorting software and hardware making it easier to operate with minimal line disruption and operational intervention.

Higher yield and consistent end-product quality

Available with 5 or 7 chutes, each featuring 64 high performance SortJet ejectors, Bühler's optical sorter DR-M provides accurate ejection at a high throughput.

Maximum profits for minimal investment

In addition to a minimal initial investment required, Bühler's DR-M has been designed to keep all running cost such as LEDs, maintenance and spare parts to a minimum with compressed air consumption reduced by up to 40%.

End-product quality up to 99.9%

Ultra-efficient RGB detection

White LED lighting provides bright, powerful light across the entire visible spectrum to ensure that the custom-built 2048 pixel RGB color cameras can see all color defects, including dark, white, red, and spot defects. A new sorting algorithm quickly reads the incoming data from the camera and efficiently determines which grains must be ejected.

Improve sorting performance

Integrated feed regulation

A consistent product stream is very important for wheat processing. Our integrated, tried and tested product flow system controls the speed and the amount of product ensuring an accurate and reliable product stream into and out the optical sorter.
