A machine was designed to separate the rind, pith, and leaves of corn stalk stalks with capacity of approximately 550 kg/h. To reasonably optimize variables of the machine operation, experiments were performed to evaluate leaf stripping and pith stripping effectiveness which was expressed as percentage. Leaf stripping was most effective with high speed and small clearance distance as machine settings with high moisture stalks. Pith stripping was most effective with high speed, small clearance distance, and larger numbers of blades.
