Abstract
A biomass cooking device including: a treatment vessel having an biomass inlet adapted to receive biomass material to a processing chamber of the vessel, a biomass outlet adapted to discharge from the processing chamber the biomass material processed in the vessel, an extraction region of the vessel and a liquids outlet to the extraction region to discharge dissolved hemi-cellulosic material extracted from the biomass material in the processing chamber; a piston press in the cooking vessel defining a moveable wall of the processing chamber, wherein the piston press moves to reduce the processing chamber and thereby compress the biomass material; and a screen plate in the vessel forming a barrier between the processing chamber and an extraction region of the vessel, the screen plate having apertures to pass the dissolved hemi-cellulosic material through the screen plate from the processing chamber to the extraction region.
