1. Apparatus for continuously mixing a fluid processing medium with a pulp suspension comprising a cylindrical rotor including a planar radial face and a cylidrical axial outer surface, a housing surrounding said rotor, said housing including a pulp suspension inlet facing the center of said substantially planar radial face of said rotor and an outlet proximate to said cylindrical axial outer surface of said rotor, gap means for forming an annular gap between said cylindrical axial outer surface of said rotor and said housing along a predetermined portion of said cylindrical axial outer surface of said rotor, said planar radial face being free of mixing protrusions and allowing a substantially unimpeded flow of said pulp suspension to permit mixing of said pulp suspension at said gap means, processing medium inlet means for feeding said fluid processing medium to said pulp suspension inlet, and turbulence creating means located at the periphery of said planar radial face of said rotor so as to create turbulence in said pulp suspension at the entrance to said annular gap.
