Pilot-Scale Milling Room

The mill, which was completely renovated in 2009, is capable of milling flour, durum semolina and whole wheat flour.  Pilot-scale or test-scale quantities of bread wheats (Hard Red Spring, Hard Red Winter and Hard White) can be milled into flour for quality and test baking/processing evaluations. Durum wheat can be milled into semolina or flour for pasta quality evaluation.

Pilot Swing Mill

NCI’s pilot-scale mill can process test-scale quantities of flour, durum semolina and whole wheat flour.

Process rate - 180 lbs./hr. wheat to first break. Optimal sample size is 300-400 lbs.  180 pounds minimum with an additional 120 pounds of wheat to warm up the Mill.

• Hard wheat target: 75% flour extraction
• Durum target: 75% extraction — 55% semolina and flour. 

Cleaning system includes a Buhler Classifier with aspiration, and a Buhler Color Sorter.  Temper using a batch system that allows multiple samples for same-day processing and optimal sample identity.

Mill consists of 18 6-inch Creason roll stands with various grinding actions, a Great Western Sifter, and 3 Buhler purifiers.  Milled product conveyed to the top floor, and gravity fed to the next processing step using Kice pneumatics.

Mill consists of a long break system with five break passages separated into course and fine breaks from 2nd Break with a bran grinding roll.  Purification system includes 3 purifiers divided into 6 purification passages. Reduction system includes 1 Sizing passage and 8 Reduction passage including 2 tailing and 6 middlings.

  • Extraction data reported.

  • Ash, protein, and rheological testing is available upon request.

  • Baking or pasta performance upon request.

  • Mill has a batch flour mixer for flour blending and enrichment addition.

  • Mill has a small bagger for easy packaging of large quantities of flour and semolina.

Buhler MLU-202 Laboratory Flour Mill

NCI can mill smaller, laboratory-scale samples of 2 to 50 pounds in its Buhler MLU-202 Laboratory Flour Mill. The Buhler Lab Mill uses a six-roll system to make refined flour products. NCI can mill a wide variety of grains that include hard spring wheat, hard winter wheat, barley, rye and ancient grain varieties.
