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 brushes or the like. In this way, work is performed that removes the material from the exterior of the seeds. A pre-conditioner may be used to prepare the seeds for introduction and a linter off-take chute may be used to remove linters. Other embodiments are presented.
