Comprising the superposition of a taper rotor (18) and an equally tapered stator (19), with refining faces directly facing each other, thereby, defining a refining zone which receives the material to be defibered, properly impregnated with vapor, from where this material leaves defibered and free of both vapors, that is, the vapor first introduced with the wood chips and the vapor generated during the defibering operation, with said rotor (18) consisting of a hub (20) as the means for attaching it to the motor drive shaft (16), interconnected by radial fins (21) to a hollow frustum housing (22-23), and also provided, at the smaller diameter end, with a front cover (24) featuring vapor passage holes (25) positioned between chip breaking blades (26), additionally, said rotor delimitates an internal sub-chamber (14) that accommodates a turbine formed by suction blades (15) rotating together with the rotor (18), for the suction of the vapor introduced and generated inside the refining chamber, with a separate side outlet (13) for the return and reclamation in equipment's continuous cooker.
