Peeling decorticator for producing undamaged natural fiber from bast fiber plants

A plant stalk decorticator comprising:

• a frame;
• a pair of feed rollers attached to the frame, the pair of feed rollers are arranged abutting one another along a substantially horizontal axis with a line of contact therebetween, the pair of feed rollers are configured to receive a plant stalk in the line of contact and at least partially flatten and feed the plant stalk below the pair of feed rollers in a substantially vertical orientation;
• a splitting wedge attached to the frame and 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 the plant stalk fed from the pair of feed rollers into two plant fiber stalk halves;
• a first pair of peeling rollers attached to the frame, the first pair of peeling rollers are arranged adjacent one another substantially parallel to the substantially vertical axis and are positioned below the pair of feed rollers and laterally from a first side of the substantially vertical axis;
• and
• a second pair of peeling rollers attached to the frame, the second pair of peeling rollers are arranged adjacent one another substantially parallel to the substantially vertical axis and are positioned below the pair of feed rollers and laterally from a second side of the substantially vertical axis such that the first pair of peeling rollers and the second pair of peeling rollers are substantially symmetrical about the substantially vertical axis;
• each of the first and second pairs of peeling rollers are configured to receive a respective one of the plant fiber stalk halves from the splitting wedge and separate the plant fiber stalk half from the respective other one of the plant fiber stalk halves thereby forming plant fiber bark sections.
