tightly concentrated then under certain conditions it can aid with the stripping of the material from the plug up to the point of its condensation the processing chamber is not depicted in fig2 however the processing chamber is shown schematically in fig3 by the supply worm 8 and the subsequent downstream disperser 7 the supply of the fibrous paper material can advantageously proceed over an angle u03b1 of approximately 45 u00b0 with respect to the perpendiculars as shown in fig2 thus an optimal trajectory of the friable material in the upper region of the processing chamber 6 arises whereas the rotors 3 have pulverization elements 4 on their periphery in fig1 and 3 the rotors can also be fixed on the face of a modified rotor as shown in fig4 in this event paddles 10 for example can be mounted on the shaft of the rotor to eddy the friable material in fig4 and 5 a type of pulverization tool is shown that has pulverizing elements 4 39 provided on the face and paddles provided on the rotor shaft 12 the fibrous pulp that is peeled off is taken up the paddles 10 that are fastened to the same rotor 12 they are whirled in a peripheral direction and hurled into the region above the rotor 12 at the same time the superheated vapor enters the processing chamber 6 from below via a plurality of vapor lines 5 39 since in.
