    摘要: A continuous process for the granulation of alcohol- and water-moist carboxymethyl cellulose (CM) produced by standard methods, wherein the CMC still moist with adhering aqueous alcohol is continuously introduced into a stirring unit, of which the length-to-diameter ratio is greater than 1 and of which the radial stirring elements are mounted on a shaft extending longitudinally in the stirring unit, and is taken up by the stirring elements, which rotate at a peripheral speed of at least 2 m/sec, being percussively size-reduced, and at the same time is brought into contact with steam flowing in countercurrent, and after a residence time of at least 1 minute, is discharged from the stirring unit and dried in the usual way.
