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.Field of SearchClosed circulating systemsAncillary to storage tank WITH PRECOAT ADDING OR APPLYING MEANS Valve controlled Spaced filters One within another Prefilt flow distributor or diverter Spaced wall-type element Medium within foraminous supporting container or sheath External cage-type support Spaced wall type, e.g., hollow leaf | |
