A discharge assembly including: a chamber having an sidewall extending around a perimeter of the chamber, an open upper region, an flange coupling at an upper region of the sidewall and extending around the upper region and a bottom, wherein the chamber receives a rotating impeller; a plurality of discharge openings in at least one of the sidewall and bottom of the chamber; a plurality of valves each coupled to one of the discharge openings, and a plurality of nozzles each coupled to one of the discharge openings and downstream in the opening to the valve for the opening.

Assembly of nozzles and valves as discharge ports of a pressurized vessel and method for switching and replacing the nozzles and valves

A reactor apparatus including: an internal mixing chamber including a first chamber section having a cross-sectional area expanding from a biomass inlet to the internal mixing chamber to the a second chamber section; the second chamber section having a substantially uniform internal cross-sectional area from the opposite end of the first chamber section to a discharge end of the mixing chamber; the biomass inlet is coupled to a source of pre-treated biomass external to the reactor vessel, and a rotating mixing device in the internal mixing chamber and coaxial with an axis of the first chamber section.

High solids enzyme reactor or mixer and method

A method to process cellulosic material in a treatment vessel including: introducing the cellulosic material to a processing chamber of the vessel; adding heat energy or pressure to the vessel to hydrolyze the cellulosic material in the processing chamber and dissolve hemi-cellulosic from the cellulosic material; compressing the cellulosic material in the processing chamber; extracting the dissolved hemi-cellulosic material through a screen from the processing section; draining the extracted hemi-cellulosic material from the vessel; and discharging the cellulosic material from the vessel separately from the extracted hemi-cellulosic material.

Method for treating, pressing and washing biomass

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.

Apparatus and method for treating, pressing and washing biomass

The invention relates to a device for dewatering and defibrating ligno-cellulose material using a screw. It is primarily characterized by a defibrating element (9) directly adjoining the body (2') of a first screw.
