Decorticating method for separating bast from core of forage chopped kenaf or the like

摘要

A method of decorticating short lengths, typically three to five inches of material such as kenaf to separate bast from core and which has been harvested by a chopper harvester of the type used for harvesting stripped corn stalks. Material is subjected to abrading by a saw blade roller and travels down a screen for treatment by a combing action which results in separation of substantially all core from bast. The core passes through the screen and the bast is swept over the end of the screen onto respective collection conveyors.
