ABSTRACT:
A method and system for filtering cooking oil in cooking vessels is disclosed. In accordance with the method and system, there is provided a collection vessel for collecting filtered oil, a filter member for filtering contaminants and particulate matter from the cooking oil, and a centrifugal pump apparatus which includes an impeller, an impeller discharge, and a flexible conduit having an inlet end connected to the impeller discharge and an outlet end. The filter member is supported in relation to the collection vessel so as to be in position to receive oil to be filtered, and then to discharge filtered oil into the collection vessel. The centrifugal pump apparatus is adapted to be placed directly in the cooking vessel so that at least the impeller thereof is in direct contact with the oil to be filtered, and the outlet end of the flexible conduit is arranged to be in position to discharge oil pumped therethrough into the filter member. When the centrifugal pump apparatus is operated, the impeller is rotated to thereby pump oil from the cooking vessel through the flexible conduit into the filter member. Also in accordance with the present invention, filtered cooking oil can be returned to the cooking vessel by simply removing the centrifugal pump apparatus from the cooking vessel, placing it in the collection vessel so that the impeller is in direct contact with the oil therein, and then operating the centrifugal pump apparatus to pump filtered oil from the collection vessel back into the cooking vessel.
