  • Publication number: 20080010853
    Abstract: Dried, singulated cellulose pulp fiber is produced by introducing wet pulp steam and air into a jet dryer. The air is heated to a temperature of 250° C. to 600° C. Steam is injected at a nozzle pressure of from 344 KPa (50 psig) to 4,137 KPa (600 psig). The pulp is removed from the jet dryer and separated from the air. The product formed has advantageous properties such as low fines count, improved kink curl and twist, and high permeability.

  • Publication number: 20080001011
    Abstract: A pulp flaker is disclosed which has a housing with an inlet and an outlet and two rotors in the housing which are parallel to each other. A plurality of fingers are arranged circumferentially and longitudinally on each rotor and on rotation the fingers of one rotor pass interspaced between the fingers of the second rotor in the region between the rotors.

  • Publication number: 20050067121
    Abstract: Methods for conveying, mixing, leveling, and flaking dewatered pulp to produce pulp flakes suitable to be used in a dryer. Methods for producing a consistent flow rate of pulp, and, for producing uniform pulp flakes in terms of pulp flake size and pulp flake moisture content. A method includes introducing a dewatered pulp to a rotating shaftless screw conveyor. The pulp is deposited from the screw conveyor onto a moving belt conveyor through a chute. The pulp is leveled with a rotary doctor located above the belt conveyor to produce a substantially even rate of mass flow of pulp along a length of belt conveyor. Uniform and consistent quantities of pulp per unit time can then be fed from the belt conveyor to a pulp flaker that then translates into an even rate of pulp mass flow to the dryer.
