Title: Rolf Bertil Reinhall: Innovator in Fiber Processing Technologies
Introduction
Rolf Bertil Reinhall is a notable inventor based in Lidingo, Sweden. He has made significant contributions to the field of fiber processing, holding a total of 4 patents. His innovative methods have advanced the way fibrous materials are processed, particularly in the production of pulp.
Latest Patents
One of Reinhall's latest patents is a method of producing fiber pulp by grinding fibrous material in a steam environment. This invention involves a grinding apparatus equipped with discs that rotate relative to one another within a casing. The process maintains superatmospheric pressure by introducing steam along with the vegetable material through a central inlet. The material and steam then pass radially outward through the interspace defined by the discs. Upon leaving this interspace, the ground pulp is exposed to a non-condensable gas, which imparts desired properties to the final product.
Another significant patent is a method of dispersing a bleaching agent into a stream of fibrous cellulosic pulp material. In this process, a stream of disintegrated fibrous pulp and steam under pressure undergoes an instantaneous pressure reduction as it passes through a throttling nozzle. A liquid solution of a bleaching agent is then mixed with the stream, resulting in a uniform dispersion of the bleaching agent into the fibers.
Career Highlights
Throughout his career, Reinhall has worked with various companies, including Defibrator AB. His work has focused on enhancing the efficiency and effectiveness of fiber processing technologies.
