FIELD: transfer of wet pulp, its heating and/or mixing with liquid or gaseous agent. SUBSTANCE: device body 1 has feed hopper 2, which receives wet pulp. By means of flights of loading zone 4 of screw 3 pulp is fed to compacting zone 5. Additional compaction of pulp occurs in cavity 8 between the last flight of compacting zone 5 of screw 3 and inlet to mixing chamber 7. Portion of compacted pulp fed to mixing chamber 7 gets disintegrated by rotating disperser 6. Transport agent and, if necessary, chemical agent and/or superheated vapor are fed to mixing chamber 7. Disperser 6 mixes the pulp with components delivered to the mixing chamber. Homogeneous and uniformly heated mixture through branch-pipe 15 is fed to any section of production line. EFFECT: expanded suitability for processing. 5 cl, 3 dwg
