  • Patent number: 11369971
    Abstract: A method of manufacturing pulp using corn stalks may include cutting the corn stalks into pieces having a length of 10 to 60 mm, separating and discharging the cut corn stalks into rind and pith using a separation unit while crushing the cut corn stalks, pretreating the corn stalks by filtering the rind and pith of the corn stalks and flakes of the rind, removing a portion of hemicellulose of the rind, and cooking the rind from which the portion of hemicellulose has been removed, using caustic soda and sodium carbonate.
    Type: Grant

  • Patent number: 10857541
    Abstract: The present invention has developed, unlike a conventional technology, an apparatus and a technique for rind, inside and scrap separation, which has been the greatest impediment to the mass production of high-quality paper-making pulp, thereby enabling the production of high-quality pulp, enables produced, unbleached pulp to be used as a raw material for manufacturing industrial packaging paper because of the excellent strength of the pulp, allows bleached corn chemical pulp to be suitable for the manufacture of toilet and facial papers and tissues, and can be applied to various paper-making techniques by mixing pulps, having different characteristics, such as needle bleached chemical pulp, leaf bleached chemical pulp, and bleached chemical thermomechanical pulp (BCTMP).

  • Publication number: 20130276998
    Abstract: A pretreatment apparatus for removing pith from cornstalks and separating husks therefrom includes a casing that receives cornstalks in a free-fall manner through an upper side thereof and allows the corn stalks to be discharged through a lower side thereof, and a rotor inserted into the casing and rotating inside the casing to hit cornstalk chips. The rotor includes a shaft inserted into the casing to be rotated by external force, a cover member holding the shaft so as to allow rotation of the shaft therein and connected to the entirety or part of an open upper side of the casing, and a hitting unit formed on a circumference of the shaft and hitting the corn stalks input into the casing.

  • Publication number: 20080295982
    Abstract: Disclosed is a process for producing pulp utilizing bamboo, comprising finely cutting the bamboo into short segments and subjecting the cut bamboo to screening and washing processes to thereby produce dissolving pulp capable of achieving reduced consumption of chemical agents used during pre-hydrolysis and pulping processes and case of reaction, and having superior quality and high yield. Further, provided are also a process for producing fiber (dissolving) pulp utilizing bamboo, capable of preventing generation of dioxin by bleaching the pulp via ECF or TCF bleaching, and a pulp produced using the same.

  • Patent number: 7186316
    Abstract: Disclosed is a method for preparing paper pulp from cornstalks comprising the steps of cooking, washing, screening, thickening, bleaching, beating and drying performed under moderate conditions which have little noxious effects on the environment. By using cornstalks as raw materials for paper pulp, it becomes possible to replace import of wood raw materials, to save foreign currency, to increase rural income, and to make high quality paper.

  • Publication number: 20040256065
    Abstract: A new method for making pulp out of agricultural residue includes harvesting certain portion of plant stalk. The harvested plant stalk is bailed, transported and stored. At the mill, the plant stalk is chopped and goes through pulping process. The pulp is used to make varieties of papers with or without blending other wood based pulp.
