  • Patent number: 5247876
    Abstract: A deep oil fryer and filtration system is disclosed wherein the filtration system (B) is disposed within a cabinet (16) of a deep oil fryer (A) having a plurality of vats (10, 12, and 14). Filtration system (B) includes a drawer having a reservoir (20) and an adjacent utility compartment (40). A pre-filter (34) is disposed in a filter basket (30) received in reservoir (20) and spaced above a bottom wall of a reservoir by the legs (32). A drain outlet (28) from the reservoir delivers cooking oil to a pump (70). A flow line system which minimizes retention of cooking oil in the lines includes a reservoir outlet line (74), a filter inlet line (78), a filter by-pass line (80), and a return line (86). Whenever by-pass valve (82) is open and pump (70) is on, pre-filtered oil from filter (36) passes through filter inlet (50) and exits filter outlet (64) without passing through a filter element ( 48) to preheat the filter. The by-passed oil is returned to the cooking vat for rinsing out the cooking vat.
