A mixer-granulator, preferably a spiral path granulator, is combined with a pneumatic conveyor dryer in a process for converting a solution or suspension into a dried particulate product. In a preferred embodiment, the particles formed in the mixer-granulator show a non-equilibrium moisture distribution with an interior part of lower moisture content and a surface part of higher moisture content.

Process and apparatus for converting a solution or suspension into a

An agglomerating unit having a rotatable, conical, downwardly, narrowing section on the interior surface of which moistened powder is deposited. Close to said interior surface a stationary scraper is mounted. When the conical section is rotated the powder is dislodged from said surface by the scraper. A very efficient removal of powder is obtained whereby the risk of biological or chemical deterioration of the powder is reduced.

Agglomeration unit

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.
