Patent number: 8123909Abstract: A papermaking raw material processor capable of reforming pulp in papermaking a process using cavitation includes a first pump 5 jets jet liquid and second pump 6 jets suspension containing; e.g., pulp fibers into a processing unit inside which cavitation is generated by generation of a jet stream. Inside processing unit 2, 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 4, except for a part of it fed to downstream steps, while the suspension is processed, as circulated between processing unit 2 and second tank 6.Type: GrantFiled: November 2, 2006Date of Patent: February 28, 2012Assignee: Nippon Paper Industries Co., Ltd.Inventors: Isao Onodera, Keigo Watanabe, Shisei Goto, Yohji Tuji, Takeshi Iimori

Patent number: 8043473Abstract: The object of the present invention is to provide a process for producing deinked pulp from recovered paper containing stickies while preventing excessive reduction in the size of stickies, lowering the COD of effluents, and producing deinked pulp with a smaller residual ink content. In the ink detachment stage of the process for producing deinked pulp from recovered paper containing stickies, an anhydride of crystalline layered silicate is added, preferably in an amount of 0.1-1.5 weight % of absolute-dry pulp, and a deinking treatment is performed at a pH of 7.0-9.9. In the present invention, the deinking treatment is performed in a weakly alkaline to neutral region which is generally said to be effective in reducing the amount of stickies but less effective in ink detachment and, yet, deinked pulp having a smaller amount of residual ink can be produced.Type: GrantFiled: March 21, 2008Date of Patent: October 25, 2011Assignee: Nippon Paper Industries Co., Ltd.Inventors: Chie Yuzawa, Hisashi Iwabuchi, Yasuyuki Kamijo, Shisei Goto, Takeshi Iimori
