摘要： A method of pulping wastepaper includes providing a pulping vessel with a rotor and at least one flow sensor to measure slurry flow within the pulping vessel. The pulping vessel is charged a slurry (wastepaper and water), the amounts of wastepaper and water being such that the slurry has consistency in the range of from 10% to 30%. The wastepaper charge in the pulping vessel is pulped at a pre-selected power level while monitoring poloidal slurry flow; water may be added when the poloidal flow falls below a predetermined lower threshold flow value to reduce viscosity and restore poloidal flow within the pulping vessel. Doppler velocimetry is a preferred method of monitoring pulp flow. In a particularly preferred construction the rotor has a variable power drive. The inventive method is especially useful for making high quality, high brightness furnishes from wastepaper which varies from batch to batch.

摘要： It is disclosed a process to transfer a ligno-cellulosic feedstock from a low pressure zone to a high pressure zone. A slurry the ligno-cellulosic feedstock is first provided, which is then subjected to a multi-step liquid removal process comprising draining by gravity at least a portion of the free liquid; removing a first portion of the capillary liquid in a low pressure zone by continuously compressing a stream of the ligno-cellulosic feedstock to reach a moisture content in a first target range; removing a second portion of the capillary liquid by shearing and compressing the ligno-cellulosic stream in a plug forming device, to form a ligno-cellulosic feedstock plug having a moisture content in a second target range at an outlet of the plug forming device connected to the high pressure zone. In the removal of the first portion of the capillary liquid, at least one first compression device continuously compresses the stream of the drained ligno-cellulosic feedstock to a first control pressure, while conveying the stream of the drained ligno-cellulosic feedstock in a flow direction of a belt filter press.

摘要： The invention relates to method and apparatus for pneumatic supply and discharge of liquid filled hollow pulp fibers, particularly as a preparatory step for passing the fibers through one or more a venturi tubes (52, 56). According to the invention the fibers are supplied into a feed chamber (12, 14, 16) by means of gas and packed by letting the gas pass through a permeable wall (34) of the feed chamber to an outlet (38). The gas surrounding the liquid filled fibers in the feed chamber is then pressurized to substantially above atmospheric pressure, and the fibers and the surrounding gas are discharged through another outlet (36) and passed through at least one venturi tube. A first venturi tube (52) may disintegrate bundles of fibers into parts, which are carried by a lower pressure gas flow (48) into a second venturi tube (56) splitting individual fibers longitudinally so as to open their lumen for further pulp treatment.

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.
