Wood fiber refining and deflaking method using specific refining members
A recently granted patent (Publication Number: US11965290B2) discloses a method for processing wood fibers involving deflaking and refining within a single refiner. The process includes utilizing a first pair of refining members with specific configurations, such as different heights of refiner bars and grooves, to effectively separate wood fiber bundles. The method further involves rotating the refining members relative to each other, supplying a wood pulp slurry through the refining space, and applying axial pressure to enhance the separation of wood fiber bundles passing through the defined gap.
Additionally, the patent claims specify various aspects of the method, including the longitudinal length of the second refiner bars, the configuration of the second member refiner bars, the zones for deflaking and refining within the refining members, and the application of axial pressure to maintain a specific gap for optimal separation. The method aims to efficiently process wood fibers by combining deflaking and refining in a single refiner, thereby improving the overall quality and characteristics of the processed wood fibers. This innovative approach to wood fiber processing could potentially lead to advancements in the pulp and paper industry, offering more efficient and effective methods for producing high-quality wood fiber products.
