Abstract
A papermaking raw material processor capable of reforming pulp in papermaking a process using cavitation includes a first pumpjets jet liquid and second pumpjets suspension containing; e.g., pulp fibers into a processing unit inside which cavitation is generated by generation of a jet stream. Inside processing unit, a jet stream generates cavitation to carry out a reforming processing in which ink, or the like, is removed from the fibers by a blast resulting from collapse of cavitation bubbles generated there. The liquid after reforming processing is returned to second tank, except for a part of it fed to downstream steps, while the suspension is processed, as circulated between processing unitand second tank
