Rotary evaporator with magnetic heating

Abstract

A rotary evaporator with magnetic heating can be used in the fields of chemical heating, desalination and biodiesel synthesis and in the environmental remediation industries. The invention relates to a rotary evaporator that comprises a cylindrical rotor (1) that is made of metal (copper, aluminium, brass, stainless steel, galvanised steel, zinc, tungsten) and contains cavities in the surface (2) thereof. The cylindrical rotor (1) rotates together with a shaft (3) supported on bearings (4) of the tops, which bearings are fitted (5) by means of screws (6) and nuts (7) into the frame (stator) (5) in which they are located; or the rotary evaporator comprises permanent magnets (8) (ferrite, neodymium, samarium-cobalt, aluminium-nickel-cobalt magnets) attached to the outside of same or a copper wire spool (9) supplied with an oscillating current within a radiofrequency range from 1 KHz to 800 KHz (10). In these arrangements, the perforated rotor (1) ejects hot water and steam under pressure out of the rotary evaporator, through a valved duct (11). It thus produces a greater quantity of steam and heat by unit of time, because of the heating caused through magnetic induction by the magnets or copper wire spools located on the rotor, during the rotation of the rotor.
