Abstract:
A method for the concentration of solutions, comprising the steps of:feeding a continuous stream of a solution 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 solution and with an opening for the discharge of a final product, a heating jacket for heating said internal wall of said tubular body to a predetermined temperature, 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 solution to form a dynamic and tubular thin layer in which the solution 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, anddischarging continuously a stream of a concentrated solution.
