Apparatus for molecular distillation by induction heating.

摘要

Molecular distillation apparatus of the type including a conical metal rotor (12) driven in rotation and fed in its centre with a liquid to be distilled, a vacuum bell (10) defining an enclosure sheltering the cone and means for heating the rotor by induction which are situated below and near the rotor. According to the invention the means for heating include at least two concentric inductors (100a, 100b, 100c) providing homologous regions of the rotor with different heating power densities. The invention also relates to a process for the manufacture of a combination of rotor and of inductors for such an apparatus.
