ABSTRACT:
An improved apparatus for filtering frying oil in a cooker apparatus includes the steps of adding diatomaceous earth to oil in the cooking vessel; draining the oil into a drain pan; drawing the oil through a filter positioned in said drain pan, such that said earth is deposited on the surface of said filter; and returning said oil to the cooking vessel. Thereafter, the oil is filtered by the steps of draining the oil into said drain pan such that the earth is not disturbed to any substantial extent off of the surface of said filter; drawing the oil through said filter; and automatically returning said oil to the cooking vessel.
The improved apparatus includes attaching said drain pan and filter to said cooker apparatus and positioning a metallic plate between the drain opening of said vessel and said filter such that the oil drained into said drain pan is initially deflected to prevent disturbing the diatomaceous earth deposited on the surface of said filter.
