Abstract:
Pulp processing equipment used to produce high-quality recycled pulp with little damage to fibers, high brightness and low residual ink by means of a force selectively acting on fiber surfaces during the process of recycling waste paper is disclosed. Moreover, fiber surfaces are modified by means of a force acting on only the fiber surfaces to obtain high-quality pulp and to render harmless dirts deteriorating pulp quality. A jet system is provided having one or more nozzles for jetting an aqueous slurry containing a material comprising cellulose into a vessel.
