摘要： 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.

摘要： 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.
