Abstract: A grease extractor incorporating a plurality of oblique baffles disposed within a barrel in angularly displaced relation with a longitudinal axis of the barrel. The oblique baffles intercross with each other at the longitudinal axis and are arranged in spaced and angularly displaced relation with each other so as to define within the confines of the barrel a plurality of congruent flow paths extending generally spirally about said longitudinal axis. When the grease-laden fumes are drawn into the grease extractor, they are forced to follow said flow paths as whirling about the longitudinal axis to move at ever-changing velocities, whereby the grease particles entrained in the fumes are subject to centrifugal action during the substantially entire course of flow to impinge continuously on the oblique baffles and the inner surface of the barrel to be deposited thereon.
