ABSTRACT:
A cooking oil filter system comprises a pre-filter for removing relatively large particles from cooking oil and a second filter assembly connected to the pre-filter outlet for removing smaller size particles. A first, inlet manifold connects the drain outlets of a series of cooking vats to the pre-filter inlet, while a second, outlet or return manifold connects the outlet of the second filter assembly to an inlet on each of the cooking vats. Valves are provided in the inlet manifold path between each vat outlet and the pre-filter, and in the outlet manifold path between the second filter assembly and each of the vat inlets. A suitable control assembly controls opening and closing of the valves to control connection of each cooking vat into the oil re-circulating and filtering system.
