Abstract
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.
Claims16
A process for deriving useful products from biomass comprising hurd, bark and bast, the process including the steps of;
- (i) sizing long stalks of the biomass,
- (ii) cutting the stalks of biomass longitudinally,
- (iii) generating a first product comprising hurd from the biomass using a rotating cutting member,
- (iv) generating a second product comprising bark from the biomass using a rotating cutting member, and
- (v) generating a third product comprising bast.
A decorticator for deriving useful products from long stalk biomass comprising hurd, bark and bast, the device including;
- a pair of rotating sizing members adapted to size the stalks when passed therebetween,
- a cutting head for cutting the stalks of the biomass longitudinally,
- a first rotating cutting member for removing a first product comprising hurd from the biomass,
- a second rotating cutting member for removing a second product comprising bark from the biomass, wherein a remaining third product comprises bast, and
- separate outlets for each of the first product, the second product and the third product.
The process of claim 15, further comprising pressing, drying, and pyrolyzing hurd or bark emerging from the counter current extractor to produce one or more of tar, wood vinegar, biodiesel, ethanol, hydrogen and biochar/graphene.
