Abstract: The feed system is for a continuous digester where at least two pumps are arranged in parallel in the bottom of a pre-treatment vessel and a liquid level of at least 10 meters is established. The system makes it possible to provide a feed system with an improved accessibility and more reliable operation, and to operate the main part of the pumps at optimal efficiency even if the production capacity is reduced.

Abstract: The feed system is for a continuous digester where at least two pumps are arranged in parallel at the bottom of a pre-treatment vessel. The transfer to the top of the digester takes place without a conventional top separator. The system makes it possible to provide a feed system with an improved accessibility and operational reliability, and to operate the main part of the pumps at optimal efficiency even if the production capacity is reduced.

Abstract: A tapered rotary feed valve is manufactured or refurbished for use in feeding materials into a high temperature environment, so as to reduce the time and expense of break-in operation, by shaping the tapered bore of the valve body at ambient temperature to have greater clearance around the rotor in a sector of the valve body that is cooler when the valve is at stable operating temperature. As a result, when the valve first reaches operating temperature after being manufactured or refurbished the rotor and the bore of the valve body nearly fit and can quickly wear in to fit each other closely.

Abstract: The feed system is for a continuous digester where at least two pumps are arranged in parallel at the bottom of a pre-treatment vessel. The outlets of the pumps are combined at a merging point before a common transfer line extends to the top of the digester. The system makes it possible to provide a feed system with an improved accessibility and operational reliability, and to operate the main part of the pumps at optimal efficiency even if the production capacity is reduced.

Abstract: A pulping apparatus includes a hollow mixing cylinder selected to retain a volume of pulping fluid and cellulose fibres therein. The mixing cylinder is journaled for rotation about a central axis oriented at approximately +20° from horizontal. In a preferred construction, the mixing cylinder is divided internally into at least two discrete mixing chambers configured to facilitate outward flow of defibred pulp from an infeed end of the cylinder to and outwardly from the outlet end. The mixing chamber adjacent the inlet end is delineated by an end cover which closes the inlet end, and by a first divider positioned across the cylinder interior. The next adjacent mixing chamber is delineated longitudinally by the distal-most divider of the end mixing chamber, and by a second further downstream divider spaced longitudinally therefrom. The dividers include at least one through-opening therethrough. The through-openings regulate the flow of pulp and fluid along the mixing cylinder, while maintaining minimum cellulose/fluid levels in each mixing chamber. The through-openings may be positioned in alignment with, or in an asymmetrical arrangement relative to the cylinder axis so as to move eccentrically relative thereto as the mixing cylinder rotates.

Abstract: The method and arrangement is for the feed of a chips suspension from one vessel to a subsequent digester in a continuous cooking process for the production of chemical cellulose pulp. The vessel has an inlet defined therein for the input of chips and an outlet defined therein for the output of a chips suspension. The chips suspension in the vessel has a first fluid/wood ratio established above a second fluid/wood ratio that is established at the bottom of the vessel. The second fluid/wood ratio is at least as great as, preferably greater than, the first fluid/wood ratio. After the output of the chips suspension from the vessel and before the chips suspension is placed under pressure for onwards transport to a subsequent digester, a fraction of fluid is withdrawn from the chips suspension, whereby a third fluid/wood ratio is established in the chips suspension.
