Research Project: Examining Gin Stands and Lint Cleaners to Improve the Quality of Upland Cotton

Location: Cotton Ginning Research

2013 Annual Report


1a.Objectives (from AD-416):
To improve the quality of upland cotton by changing the operating parameters of gin stands and lint cleaners.


1b.Approach (from AD-416):
Gin stands and lint cleaners are two of the principal machines used to convert raw seed cotton into marketable products of fiber and cottonseed. Improving these machines to produce a higher-quality fiber will make upland cotton more desirable and more competitive in the world market.


3.Progress Report:

This Agreement is a continuation of work that attempts to remove seed coat fragments (SCFs) from ginned lint on a saw-type lint cleaner. Preliminary testing was conducted on a newly designed air knife attached to the first (of five) lint cleaner grid bar. The air knife is intended to help remove seed coat fragments from ginned lint by blowing the fragments out of the lint stream and into the trash stream. The air knife was tested at three air pressures. Video from a high-speed camera showed that the air knife appeared to remove some seed coat fragments. A formal test will verify if this is true. This research will be the basis for a future journal publication.
