Abstract
A plant stalk decortication apparatus and method are provided. The apparatus includes an alignment system in which a series of rotating spindles with blades attached to the spindles are positioned over a bed on which plant stalks are longitudinally aligned and conveyed by the blades. The apparatus also includes rollers and breakers downstream of the blades for crushing and breaking the plant stalks to cause the bast fibers and hurd to separate. The apparatus also includes a suction chamber that separates loose bast fiber from hurd chips formed by the breakers.
