Abstract
Abstract AN APPARATUS FOR REMOVING GREASE, OIL AND FAT FROM ARTICLES CONSISTS OF MEANS FOR BOILING A SOLVENT SO THAT THE VAPOR FILLS A CHAMBER IN WHICH THE COOL ARTICLES ARE PLACED. THE ARTICLES ARE SITUATED IN A ROTATABLE CYLINDER WHICH MOVES THE ARTICLES DOWN INTO THE VAPOR ZONE AND UP FROM THE VAPOR ZONE. THE CYLINDER IS OF SUCH A SIZE THAT IT NEARLY FILLS THE CROSS SECTIONAL AREA OF THE APPARATUS, THUS REDUCING THE LOSS OF SOLVENT FROM THE VAPOR ZONE.
