We recently purchased a Nufab grain cleaner with neighboring farmers. The main idea is to grade out-of-spec grain to ensure it meets delivery standards and value add to our produce before it leaves the farm gate. Cleaning seed for planting is also an advantage. The 6 screen grain cleaner has a high capacity and is capable of grading all the grains we grow – from canola to fababeans. (click on pics below to enlarge) See Nufab Industries for more info.
