  • Method and apparatus for drying disintegrated fiber mass
    Patent number: 4055903
    Abstract: A method and apparatus for drying disintegrated fiber mass or paper pulp comprising substantially free single fibers and wads or lumps of fibers. The disintegrated fiber mass is exposed to hot drying air or gas at a temperature of at least 180.degree. C. Free fibers are separated from the fiber mass during or after the drying process in order to avoid or compensate for excessive heating and drying of these free fibers. This facilitates a later grinding process in which the dried fiber mass is ground after addition of water.
