Abstract: Systems and methods for removing material, e.g., linters, from seeds, e.g., ginned cottonseeds, are provided. The systems and methods involve rotating the seeds in a rotatable drum having a plurality of longitudinal brushes. The centrifugal force created by the rotation of the drum and the plurality of longitudinal brushes urge the seeds against an interior surface of the drum that is lined with a brush insert. In this way, work is performed that removes the material from the exterior of the seeds. The material is removed using reduced pressure and the processed seeds are removed. The system may include a brush insert that is easily removed from the rotatable drum. Other systems and methods are disclosed.

Abstract: A device for removing foreign matter that collects on a cleaning bar in an apparatus for cleaning fibers of material. The device includes a scraper slidably mounted on a cleaning bar, such as a grid bar in a lint cleaner for scraping foreign matter and lint off the grid bar when the scraper slides along the length of the grid bar. The scraper includes a scraper bar that is in sliding contact with a top surface of the grid bar. The edges of the scraper may be sharp to improve the scraping efficiency. A scraper back plate extends from the scraper bar. The scraper and back plate are mounted on the grid bar using a guide block so that the scraper is slidable along a length of the grid bar. A guide rail may be mounted first on the grid bar to facilitate mounting of the scraper on the grid bar.

Abstract: A roller gin capable of producing lint substantially free of linter fibers utilizes a wall construction to prevent the seed from contacting the ginning roll, a ginning slot in the wall through which an airflow draws the fibers. A ginning roll adjacent the slot on the opposite side of the wall grasps the fibers along a nip point formed between the roll and wall proximal the slot and urges the fibers along a path on one side of the wall while the seeds are urged along a divergent path on the other side of the wall.

Abstract: An improved process and equipment for seed defiberization, for example cottonseed delinting, wherein the seed is defiberized by contact with particular abrasive surfaces. In one preferred embodiment, a conventional cotton-seed delinter is equipped with an abrasive faced cylinder instead of the conventional shaft mounted ginning saws. The abrasive cylinder comprises a shaft mounted cylinder of approximate gin saw diameter which cylinder has bonded or adhered to its facial surface an open pattern of about 40 to about 80 abrasive grit particles per square inch. The abrasive grit particles, preferably tungsten carbide grit, are sized to U.S. Sieve Series numbers of about 12 to about 40. Replacement of the ginning saws with the abrasive face cylinder requires modification to the delinter gratefall rake and seed seals to adapt their shape and clearance to the comparatively flat abrasive cylinder face.
