APPARATUS FOR MOLECULAR DISTILLATION Russian patent published in 1996 - IPC

FIELD: chemical engineering. SUBSTANCE: apparatus for molecular distillation with a rotor placed between evaporator and condenser, possessing roll-type grinding members and applience to fix rolls with their axles, is improved in the following. Roll-fixing applience is made in the form of mounts, each of them being provided with slates arranged along vertical axis. Mounts are further provided with front and back stop members interacting with slates and having keepers embracing the rolls, which are placed on radially mouvable individual axles. Clearance between a slate and a front stop member is less than that between a slate and a roll, and rolls of adjacent mounts are shifted along vertical axis to half distance between the rolls. EFFECT: increased capacity and reliability of apparatus because of excluding friction between the rolls.
