ABSTRACT

Tests were conducted over a three-year period to investigate the effects of various seed cotton cleaners, saw gin stands, and saw-type lint cleaners on the amount and size distribution of trash in cotton. Seed cotton cleaners and extractors effectively removed large trash particles from the cotton, but they were only marginally effective in reducing the amount of fine trash and pepper trash in the cotton. Saw gin stands tended to generate fine trash and pepper trash, especially if the seed cotton contained a significant amount of large leaf Saw-type lint cleaners, on the other hand, were highly effective in removing the finely divided trash created by the gin stand. Overall, the ginning process reduced fine trash and pepper trash counts by about 70 percent, small leaf by about 80 percent, and large leaf by 98 percent.
