A configurable apparatus is operable for decorticating, comminuting and liberating fibers and hurd from hemp stalks and related materials using selective differential fragmentation. The apparatus is selectively configurable for processing different materials. The configurable apparatus includes a plurality of sides formed of hinged, segmented outer doors, a splined central rotating shaft extending longitudinally within the apparatus, and a plurality of matching splined processing rotors selectively spaced apart and coupled to the central rotating shaft, each of the plurality of processing rotors contained within a different processing chamber within the apparatus.

A plant stalk decorticator includes a pair of feed rollers arranged abutting one another along a substantially horizontal axis with a line of contact therebetween. A splitting wedge is positioned at least partially below the pair of feed rollers and aligned along a substantially vertical axis that is substantially centrally located in the line of contact between the pair of feed rollers, the splitting wedge is configured to split a plant stalk fed from the pair of feed rollers into two plant fiber bark sections. Symmetrical pairs of vertically stacked peeling rollers are positioned below the pair of feed rollers and laterally from either side of the substantially vertical axis. Each of the pairs of peeling rollers are configured to receive a respective one of the plant fiber bark sections from the splitting wedge and separate the plant fiber bark section from the respective other one of the plant fiber bark sections.
