Patent ID: 6837969

Claim:
A method for concentration for liquid mixtures, comprising the steps of: feeding a continuous stream of a liquid mixture into a turbo-concentrator comprising a cylindrical tubular body which has an internal wall, a horizontal axis and which is equipped with an opening for an introduction of the liquid mixture and with an opening for the discharge of a final product, a heating jacket for heating said internal wall of said tubular body, and a bladed rotor rotatably supported in said cylindrical tubular body where said bladed rotor is rotated at circumferential speeds variable from 30 to 50 m/s, centrifuging the liquid mixture to form dynamic and tubular thin layer in which the liquid mixture is maintained in a state of turbulence by the blades of said bladed rotor, advancing said dynamic and tubular thin layer to said discharge opening of the turbo-concentrator, causing said dynamic and tubular thin layer to flow substantially in contact with said heated internal wall to the discharge opening, and discharging continuously a stream of a concentrated liquid mixture.
