Protein Sorting of Grains
Sorting grains based on their raw protein content allows for upgrading a portion of a grain batch from feed to food quality.

By Linda Rosager Duve

Barley and wheat grains can be sorted with an NIR-T sorting system (Near Infrared Transmission), which illuminates the grains with infrared light and thereby determines their relative raw protein content. The illuminated grains are divided into two batches based on a predetermined threshold value for sorting. The mobile system, which the Innovation Center for Organic Agriculture has helped test, has a capacity of approximately 4 tons per hour. This corresponds to sorting about 22,000 grains per second.

Sorting out grains with either a high or low raw protein content is both technically and practically feasible for batches of wheat and barley, respectively. This means that the new protein sorting system may help you save part of a grain batch, if its quality is on the borderline, to be approved for food use in the future.

Gl. Buurholt are experts in cleaning, dressing, and handling seed grain.
We have built all our machinery as mobile units. We travel from farm to farm and process the grain so that it is ready for sowing. We have equipment for seed grain, silo cleaning, dehulling, protein sorting, and flour production.
