Using Newly-Designed Lint Cleaner Grid Bars to Remove Seed Coat Fragments

Controlled-batt saw-type lint cleaners use grid bars to remove foreign material from cotton fiber such as leaf particles, motes, grass, bark, and seed coat fragments (SCFs).  A study was done to evaluate the effectiveness of newly-designed grid bars in removing SCFs.  The grid bars were tested on a full-size conventional lint cleaner.  The grid bars consisted of five experimental designs and a control.  Two cotton cultivars were used.  One of the cultivars was prone to having a fragile seed coat that breaks easily and contaminates lint with SCFs.  Fiber tests will determine which grid bar(s) removed the most SCFs.
