Initial Fiber Quality Comparisons of the Power Roll Gin Stand to Three Different Makes of Conventional Gin Stands

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 article reports High Volume Instrument and Advanced Fiber Information System fiber property results from three field tests evaluating the technology on three different makes of gin stands. Results indicate the powered roll gin stand performed equal to or better than some of the conventional gin stands in processing rate, lint turnout, and/or some fiber properties. However, work remains to refine the technology so that it performs consistently on different makes of gin stands.

The Impact of Historical Gin Stand Technologies on Cotton Fiber and Seed Quality

“…In another study, ginning rates from 305 to 1,393 kg (1.4 to 6.4 bales) of lint/h did not significantly affect nep count for a gin stand rated at 1,043 kg (4.8 bales) of lint/h (Mangialardi et al, 1988). Holt and Laird (2007, 2008, 2010 conducted more recent studies on their patented powered roll gin stand to increase production and turnout without reducing fiber quality. The main operational components of the technology were the paddle roll that actively turned the seed roll and seed finger roll that presents unginned cottonseed back to the saw.…”
