  • Patent number: 5137493
    Abstract: A corn husking machine has a hollow cylindrical drum defined by a circumferential wall rotatable about a substantially horizontal longitudinal axis. The drum wall has at least one aperture therethrough which is suitable for unhusked ears of corn to pass through from outside the drum to the hollow interior of the drum. A station is affixed to an interior portion of the drum wall adjacent each aperture and extends into the hollow of the drum. Each station has two elongated rollers positioned side by side, which are rotated in opposite directions, so that at a nip formed by adjacent surfaces of the rollers, husks of unhusked ears of corn passed through the adjacent aperture are seized by the rotating rollers and stripped off the ears and pulled between and through the nip. The husks are collected in a central portion of the hollow of the drum. For husking ears of minicorn, the rollers have a diameter of from 1 cm to 3 cm and are rotated at a speed of from 20 rpm to 250 rpm.
