Current decortication methods provide hemp or flax fiber in a tangled mess with significant damage to the individual fibers. FibreWerks has team invented a patent pending decortication process that mimics the manual peeling of bark, in ribbon form, from the woody inner core (hurd, shive) of a hemp or flax stalk. Our early stage process invention presents a radical departure from the current decortication approaches that sacrifice fiber quality for high throughput, as it produces hitherto unrealizable, high-quality, undamaged fibers in ribbon form for high-value biocomposite applications. The new process feeds rows of cut, unretted, and dried stalks downward through a set of rubber-coated pinch rollers to crush and flatten the stalk, and then into a stationary knife wedge to split the crushed stalk in half. A second set of pinch rollers (with larger diameter bottom roller) diverts the half stalk sideways thereby breaking the tip of the hurd/shive stem and starting the bark-peeling process. A symmetrical set of rollers repeats this step for the other stalk half. The wedge rapidly descends out of the way so that the peeled hurd/shive stem moves downward unhindered to be ground up below (e.g., for animal bedding, hempcrete). The bark with undamaged fiber exits on both sides of the machine, where it can either be left as a continuous ribbon or cut to customer-defined lengths, e.g., via an oscillating serrated blade or rotating cutter.
