Interpretive Summary: A new model (24-D) lint cleaner for use in cotton gins is now available commercially but sound research data on its cleaning efficiency is not available. This study was conducted to establish the cleaning efficiency of the new lint cleaner which is equipped with a 24-in. diameter cleaning saw compared to a standard lint cleaner equipped with a 16-in. diameter cleaning saw (16-D). The new lint cleaner was 48% more efficient than the standard lint cleaner and produced bales of higher monetary value and less damage. Use of the new lint cleaner by industry will increase bale value at least $3.00 per bale. Higher values can be obtained with selective use of the more efficient cleaner.

Technical Abstract: A saw-type lint cleaner equipped with a 16-in. diameter cleaning saw cylinder was compared to one with a 24-in. diameter saw cylinder individually and in combination. Based on Shirley Analyzer lint foreign matter content, the 24-D lint cleaner removed more foreign matter than did the 16-D lint cleaner either when used alone or in combination with another 16-D lint cleaner. The amount of material removed per bale by the 24-D lint cleaner was about 1-lb more than that removed by the 16-D lint cleaner. The 24-D lint cleaner had a higher cleaning efficiency than did the 16-D lint cleaner either when used alone or in combination with a 16-D lint cleaner. From a classer's leaf grade standpoint, the 24-D was about 1/2 leaf grade better than the 16-D. In terms of improvement in the color of the cotton, there was essentially no difference between the 24-D and the 16-D. The 24-D produced bales with a higher monetary value than the 16-D. The 24-D lint cleaner is superior to the 16-D lint cleaner in terms of cleaning efficiency and bale value. This study represents the response of two cottons grown near Stoneville, MS; other cottons may respond differently.
