Abstract: Process for the purification of products of regenerated cellulose in which the regenerated cellulose product is passed through at least one washing segment where it is initially squeezed out with the aid of a squeezing element and then washed out with the washing water, passed in counter current, while simultaneously being deflected over deflection elements.

Abstract: 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.
