The mass is guided along a path which is largely free of abrupt turnings. An Independent claim is included for equipment carrying out the method. Screw rotors (3, 11) are mounted in bearings, leaving one end floating. Their outlet connections (10, 20) continue essentially in the axial direction of the screw rotors. Preferred Features: The outlet connections are conical. They are fitted axially or eccentrically with respect to the axis of the screw rotors. The bearings (6, 13) are located at the inlet ends of the screw rotors, which are heated. The steam supply (7, 15) is delivered to an internal chamber of the rotor and as appropriate, to the rotor spirals. Condensate drains (8, 16) leave from the screw stub shafts (6a, 13a) which are carried in the bearings. Screw rotors form parts of a system conveying mass (B) from heating equipment, or a steaming chamber (2) following it, to a cooling conveyor belt. The conveying system comprises an extraction screw (A) and a screw mixer (M) following it. The extraction screw may follow several screw mixers. Its spiral has a non-constant pitch. The diameter of the rotor (3) shaft of the extraction screw within the product chamber, is non-constant. |
