Mechanical post-harvest processing devices for processing plant material by separating a desired portion of plant material from an undesired portion of plant material are shown and described. The mechanical post-harvest processing devices each include: a saddle having a plant material container-proximate region and one or more saddle openings a plant material container having one or more plant material container openings and an exterior surface proximate the saddle and circumferentially enclosing a post-harvest processing space and a rotary actuator mechanically connected to the plant material container and configured to rotationally drive the plant material container such that the plant material chamber rotates within the saddle. In some examples, a portion of the one or more plant material container openings and a portion of the one or more saddle openings overlap at one or more positions during rotation of the plant material chamber.
