About Northwest Seed Cleaning Service Inc.
Northwest Seed Cleaning Service is a mobile and stationary grain cleaning and grain conditioning company in Buxton, North Dakota with a stationary processing plant in Cummings, ND. Established in 1992, its first mobile cleaning rig was built that same year, consisting of a CRIPPEN DK-488 Air Screen machine and a CRIPPEN G-6846 Gravity Separator. At that time, it was primarily used for cleaning scab wheat from good wheat. With this rig, over three million bushels of scab wheat were cleaned from 1992-1994.
In 1995, after the scab wheat problem became less widespread, Northwest Seed Cleaning Service experienced a great quantity of volunteer barley in the wheat crop across western North Dakota and eastern Montana. A second rig was built especially for this separation using an IDEAL Cylinder Mill.
Then in 1996, Northwest Seed Cleaning Service built a third rig, consisting of a sieve, a cylinder, and a gravity mill to custom clean cereal grains for seed. In the fall of that year, a Crippen S-56 Stoner was added to adapt this unit for the custom cleaning of edible beans for market shipments and for seed.
Since 1996, Northwest Seed Cleaning Service has built two additional rigs similar to the third for in-house purposes as well as three others for customers.
Today, Northwest Seed Cleaning Service provides services for processing companies throughout the United States with all three of its seed cleaning rigs.
