Claim:
Centrifugal rotary device for heating and/or vaporizing liquids, comprising a casing within which is positioned a truncated chamber having an inlet orifice, through which a liquid to be heated is introduced, and an outlet orifice through which heated liquid and/or vapour emerges, the truncated conical chamber of the casing having a lateral surface, a major base and a minor base, and being provided with opposing coaxial apertures formed in the major and minor bases respectively, and comprising a pair of hollow truncated conical rotors positioned coaxially one inside the other, with both rotors located inside the truncated conical chamber, this pair of rotors including an inner rotor adapted to rotate in a first rotation direction, having corresponding head and shell portions, fixed to the end of a first drive shaft passing through the aperture formed in the major base of the truncated conical chamber, and an outer rotor adapted to rotate in a second rotation direction opposite to said first rotation direction, having corresponding head and shell portions, fixed to the end of a second drive shaft passing through the aperture formed in the minor base of the truncated conical chamber.
