RT Journal Article SR Electronic T1 Seed Cleaning: Improvements to the brush cleaning comb JF Native Plants Journal JO NATIVE PLANTS JOURNAL FD University of Wisconsin Press SP 38 OP 44 DO 10.3368/npj.11.1.38 VO 11 IS 1 A1 Barner, Jim H A1 Windell, Keith YR 2010 UL http://npj.uwpress.org/content/11/1/38.abstract AB An improved brush cleaning comb has been developed by the Missoula Technology and Development Center using an approach suggested by the USDA Forest Service’s Bend Seed Extractory. Brushing machines remove the awns (stiff, slender, sometimes barbed stalks) when grass seeds are cleaned. Rotating brushes cut off the awns by scraping the seeds against the brushing machine’s wire mesh mantle screen. The improved brush cleaning combs keep the awns from clogging the rotating brushes.
