ABSTRACT:
A method for filtering edible oils utilizing a backwashable filter assembly. A filter system having at least two filter assemblies may be utilized to remove bleaching clay and/or nickel catalyst from oil being processed for human consumption. The filter assemblies may be connected in a series and tandem manner to provide continuous and uninterrupted filtering of the edible oil. Each filter assembly preferably comprises multiple, substantially cylindrical filter elements having a porous filter medium which may be formed from polyaramid fibers. The filter elements are designed to withstand the elevated temperatures used in edible oil processing and for ease of cleaning during backwashing.
