FOERFARANDE OCH APPARATUR FOER BEHANDLING AV CELLULOSAHALTIGT MATERIAL

METHOD AND APPARATUS FOR THE TREATMENT OF A CELLULOSE-CONTAINING MATERIAL A b s t r a c t Disclosed is a method for the treatment of a cellulose -containing material basically comprising the steps of continuously charging the material together with the solution of reagents into a working chamber and repeatedly machanically compacting the same by means of the cooperation between an inner and an outer working bodies, the outer working body enclosing the inner working body and defining in combination therewith the aforesaid working chamber. The step of repeatedly mechanically compacting the material is effected by imparting to one of the working bodies wobbling and rolling over the other working body through a layer of the material treated, the aforesaid wobbling and rolling being produced by the rotation of a mass unbalanced with respect to the axis of rotation and coupled ratably to one of the working bodies. Also disclosed is an apparatus for practising the above method, which comprises a housing, a rotor made in the form of a body of rotation arranged inside the housing and defining in combination therewith a working chamber, a means for charging the cellulose-containing material together with the solution of reagents into the aforesaid working chamber, a drive shaft and its driving gear. Mounted on the drive shaft are unbalanced masses, 9 while the shaft itself is rotatably coupled to the rotor or to the housing, a portion of the surface of the rotor being designed for repeatedly mechanically compacting the material treated.
