Patent number: 7601243Abstract: System for conveying, mixing, leveling, and flaking dewatered pulp to produce pulp flakes suitable to be used in a dryer. The system produces a consistent flow rate of pulp and uniform pulp flakes in terms of pulp flake size and pulp flake moisture content. The system includes a rotating shaftless screw conveyor for mixing and conveying dewatered pulp. The system includes a belt conveyor. The pulp is deposited from the screw conveyor onto the moving belt conveyor through a chute. The system includes a rotary doctor. The pulp is leveled with the 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.Type: GrantFiled: May 19, 2008Date of Patent: October 13, 2009Assignee: Weyerhaeuser NR CompanyInventors: Ramon C DeZutter, Christopher Q Tveter

Patent number: 7396435Abstract: 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.Type: GrantFiled: September 29, 2003Date of Patent: July 8, 2008Assignee: Weyerhaeuser Co.Inventors: Ramon C. DeZutter, Christopher Q. Tveter

Patent number: 7306846Abstract: Discrete particles of cellulosic material are flowable and meterable. They are easily dispersible in an aqueous or a dry medium. The particles comprise singulated cellulose fibers that have been densified. The particles have a density of at least 0.3 g/cc.Type: GrantFiled: August 19, 2005Date of Patent: December 11, 2007Assignee: Weyerhaeuser CompanyInventors: Ramon C. Dezutter, Michael R. Hansen

Patent number: 6837452Abstract: A process for making singulated pulp flakes is provided. The process includes dewatering liquid pulp stock to a consistency of about 30 to about 50% solids. The process includes initial flaking to break up the dewatered pulp bundles into semi-uniform flakes having a median size of from about 3 to about 5 mm3 and a consistency of from about 33 to about 55% solids. The process includes drying the flaked pulp to a consistency of from about 85 to about 97% solids. The process includes flaking a second time to separate the flakes that may have bonded during drying. The product “singulated” flakes then go to a baler for packaging. In another embodiment, the process includes blending the liquid pulp stock with at least one adjuvant prior to dewatering.Type: GrantFiled: August 30, 2002Date of Patent: January 4, 2005Assignee: Weyerhaeuser CompanyInventors: Ramon C. Dezutter, Brian Wester, Robert A. Veleber, Michael R. Hansen

Patent number: 6811879Abstract: The present invention is directed to a new form of pulp that is a flake having a specific size, density, and wet dispersibility. The flakes are easy to meter in specified quantities when adding to cementitious products, because bulk quantities of the flakes flow well in conduits and other enclosed containers. The pulp flakes can supply sufficient cellulose fiber to an extrusion process due to the flakes' high fiber density. The pulp flakes have a wet dispersability that is comparable to some pulp sheets that have not been hammermilled. In one embodiment of the invention, a pulp flake is provided that has a wet dispersion of from about 60 to about 240 counts as measured by a standard British disintegrator. Another embodiment of a pulp flake has a density of from about 0.3 to about 0.7 g/cc. In one embodiment, the pulp flake has a size of from about 3 to about 5 mm3.Type: GrantFiled: August 30, 2002Date of Patent: November 2, 2004Assignee: Weyerhaeuser CompanyInventors: Ramon C.
