摘要:
Disclosed herein are methods, systems, and compositions for the pretreatment of biomass within seconds with low inhibitor formation. The pretreatment process is used to convert biomass to a fuel or other useful chemicals by subjecting the feedstock to a rapid retention time under pressure and temperature and/or chemical reactant. The system includes a continuously-operating valve discharge apparatus to discharge pretreated feedstock while maintaining uniform pressure on the pretreatment system.

System for the processing of organic waste and products, which is equipped with, at least, one cylindrical cavity (1) of treatment which is arranged with a loading area (12) and a unloading area (13) of waste and an entrance (14) and exit (15) of vapour. Inside the cylindrical cavity (1), dragging spindle (2) with direction of advance from the loading area to the unloading area is installed. The axis of the dragging spindle is equipped with mixing blades (11) which conform a mixing spindle with a direction of advance opposite to that one of the dragging spindle.
摘要:
A method and apparatus for conveying a cellulosic feedstock are disclosed. The apparatus, such as a holding tank, has a passage. At the outlet to the passage, a conveyance member is provided to convey the cellulosic feedstock laterally across the outlet. The conveyance member, e.g., at least one screw conveyor, may have a variable pitch along its length. The method comprises passing the cellulosic feedstock through an impregnation chamber to an outlet of the impregnation chamber; passing the cellulosic feedstock from the outlet of the impregnation chamber to an inlet of a holding tank; passing the cellulosic feedstock downwardly through the holding tank; maintaining a generally constant residence time in the holding tank; and subsequently subjecting the cellulosic feedstock to a hydrolysis process.

A material handling system 100 for moving material from a storage device 1 to a receiver comprises a counter rotating double screw feeder 3 extending from the storage device to the receiver. The counter rotating double screw feeder 3 comprises an outer screw feed member 4; an inner screw feed member 5; where the outer screw feed member being positioned in an outer screw feed member tube; and the inner screw feed member being positioned in an inner screw feed member tube. The material is feed from the storage device 1 to the process tube 6 via the outer screw feed member; the inner screw feed member removes gas and byproducts from the receiver.

Die Erfindung betrifft einen Doppelschneckendosierer für volumetrische und gravimetrische Dosieraufgaben. Dabei sind zwei horizontal parallel nebeneinander kämmend angeordnete Dosierschnecken (3, 11) vorgesehen, deren Lagerung (2, 12) und Antriebselemente (1, 13) horizontal gegenüberliegend angeordnet sind. Diese Doppelschneckendosierer sind für sehr kleine Förderstärken und anhaftende Schüttgüter vorgesehen, wobei die einzelnen Dosierschnecken (3, 11) Durchmesser von 2 bis 15 mm aufweisen.
摘要:
An apparatus and method for continuously dispensing dough for making bread, rolls, buns and the like by pressurizing and homogenizing the dough by a pair of open-flighted augers (42) in a tunnel (48) having minimal clearances so that the dough is provided with a uniform texture and density which permits a division into pieces having weights with tolerances within one-half of one percent.
