A decorticating machine comprising modular drum assemblies of different tooth and surface patterns that are installed between pairs of left and right lower and upper rails is described. The modular drum assemblies (usually provided in upper and lower drum pairs) and the number thereof can be chosen based on the particulars of the type of stalk being processed.

A method and device for harvesting plants belonging to the family of hemp plants (Cannabaceae), in particular of the genus Hemp, with which the harvesting and separation of the individual plant parts is made possible without damaging the individual plant parts. In particular, during harvesting, the hemp stems are pulled downwards by a pair of rollers and the flowers are pulled backwards through a chain gap, whereby the flowers are stripped from the stems.

There is provided a device, process and system for decortication of biomass comprising hurd, bark and bast, such as long stalk biomass. Typically, one or more of the bark, hurd or bast generated by the decortication process or decorticator device is fed to a downstream process or downstream device such as a counter current extractor. The liquid or fibre products of decorticator, or the decorticator in combination with the counter current extractor may be further processed into their components.

The method disclosed relates to the production of paper yarn from cellulose-containing plant species, in the textile sector, and particularly relates to obtaining a paper yarn by a wet spinning method using high or low purity cellulose raw material isolated from the wild plant species of Calluna Vulgaris.

A stem breaking apparatus includes a roller having unevenly spaced radial projections and is useful in a method of extracting bast fibers from a plant stem. The roller is one of a pair of intermeshed counter-rotating rollers between which the plant stem is passed to break the woody core of the stem for separation from the bast fibers. Pairs of adjacent projections are angularly spaced by a larger amount that the individual projections of each pair. The rollers provide a larger support span than conventional stem-breaking rollers, resulting in gentler breaking of the woody core and preventing or eliminating the kinks and inter-fiber splitting associated with conventional stem breaking. Pre-compression of the stems before breaking offers further advantages.

A system and method for producing bio composite materials by mixing pelletized plant fiber dust and virgin or recycled plastic. The system may comprise a reducer, a press, a dryer, a pelletizer, and a mixer. The reducer separates the fibers of the plant material and the press removes liquid from the separated fibers. The dryer further reduces the moisture content of the pressed fibers and generates dust which is extracted by sifting, screening, or another suitable method. The pelletizer compresses and/or treats the fiber dust with solutions, adhesives, or other processes that cause the fiber dust to adhere together. The fiber dust pellets are then mixed with virgin or recycled plastic to produce a bio composite material.
