ABSTRACT:
Elastic scraper for high-capacity continuous molecular evaporation and reactors with a wiped-off film, the scraper being in the form of a plurality of wiping segments mounted upon a wiping device having a plurality of circumferentially spaced parallel supporting rods which rotate with respect to the surface of the apparatus from which the film is to be wiped. The wiping segments are held from above by an elastic spring which connected them to their respective supporting rods. The supporting rods may be floatingly mounted, as by connecting segments which are mutually joined whereby to provide the supporting rods and the wiping segments supported thereby with limited concumferential movement with respect to the surface to be wiped.
