Citation: Holt, G.A. 2004. Fiber quality preservation using the powered roll gin stand. IN: Proceedings of the Engineered Fiber Systems Conference, June 6-8, Greenville, SC. 2004. CD-ROM. Interpretive Summary: The powered roll gin stand was initially developed to regin cottonseed in order to remove as much residual lint as possible for the EasifloTM process. Various studies have been conducted evaluating its use in ginning seed cotton. In 2003, eleven cotton gins installed the power roll technology on eighteen gin stands. This paper reports on comparison studies conducted in three commercial cotton gins operating different makes and models of gin stands during the 2003-04 ginning season. The cotton gins were located in Arkansas, California, and Texas. Results showed the best performance was obtained on the same model of gin stand as the initial prototype evaluated at the USDA-ARS gin lab in Lubbock, Texas. Overall, the power roll technology shows great promise and should be optimized for different makes of gin stands currently in use. Likewise, the power roll gin stand's operational components make this gin stand a good candidate for real-time process control. The potential for this gin stand to perform "prescription ginning" is discussed.
Technical Abstract: The powered roll gin stand is a new saw-type ginning technology that has undergone numerous studies evaluating its use for ginning seed cotton. Past results have shown increased production and turnout without adversely affecting fiber properties. In some cases, improvements in fiber properties over a conventional gin stand were demonstrated. This paper reports on results from three recent field tests evaluating the technology on three different makes of gin stands. Current and planned future studies are also discussed, including the potential to use this technology for real-time process control of fiber properties.
