ABSTRACT:
The invention relates to a molecular distillation apparatus of the type comprising a metallic conical rotor (12) rotatably driven and fed in its center with a liquid to be distilled, a vacuum bell (10) defining an enclosure housing the cone and means for inductively heating the rotor which are located beneath and in proximity to the latter.
According to the invention, the heating means comprise at least two concentric inductors (100a, 100b, 100c) supplying different thermal power densities to homologous regions of the rotor and an inner inductor (100a) supplies a greater thermal power density to the rotor than the power density supplied to the rotor by an outer inductor (100c).
The invention also relates to a process for manufacturing an assembly of a rotor and inductors for such an apparatus.
