The invention relates to a turbomixer-extruder machine, with a single rotating screw 1 of helical flights, characterised in that the fixed barrel 2 of the extrusion chamber is provided with a plurality of zones with sets of hydrodynamically profiled directing blades 3, extending beyond the internal surface of the extrusion chamber, it being possible for their angle of action to be varied by driving from the outside and for them to be substituted by others, so as to give the profile suitable for the viscosity of a substance (mass) being worked, and in that, in the zones 4 where the directing blades are located, the flights of the screw have a lower height and act as radial- and axial-action blades. <IMAGE> |
