  • Fryer filtration arrangement
    Publication number: 20020092803
    Abstract: A fryer filtration arrangement includes an oil drain pan and associated filter assembly. The filter assembly may be removably connected to the pan by a friction fit coupling arrangement. The pan may be positioned in latch-free movable drawer. The fryer vat may be shaped such that particulate matter settles therein along a substantially linear region and oil circulated during a filtration operation may flow along the substantially linear region to push the settled particulate matter to the pan and filter assembly.
