Abstract

Frying apparatus including a fry pot and a filter system operable during a cleaning cycle for dislodging food particles which cling to the fry pot and for removing food particles suspended in the cooking oil is disclosed. The filter system includes a shower apparatus which discharges jets of cooking oil along the interior side surfaces of the fry pot to dislodge food particles clinging thereto. The cooking oil is drained into a drain pan, strained through a filter and means are provided for pumping the filtered cooking oil back to the fry pot where it is discharged through the shower apparatus. Food particles are continuously separated from the cooking oil as it is conveyed from the fry pot through the filter into the drain pot. In a preferred embodiment, a control circuit is provided for automatically turning off the fry pot heaters when the cooking oil is drained during the filter cycle. The control circuit includes means for locking the fry pot heating system in the off condition when the draining operation occurs. Reset is accomplished by first turning the fry pot off and then back on to insure that the operator exercises positive control before the heating system is energized.

In a fry pot of the type having an interior side surface formed by the union of first, second, and third planar surfaces, the first planar surface having an edge which cooperates with the remaining interior side surfaces to define the mouth of the fry pot, the second planar surface projecting laterally from the first planar surface into the fry pot thereby defining a ledge, and the third planar surface being disposed intermediate the ledge and the floor of the fry pot, and wherein a fluid coupling member having a discharge port is mounted through the third planar surface beneath the ledge, the combination with the fry pot of a removable shower apparatus for insertion into the fry pot to discharge jets of cooking oil along the interior side surfaces, the shower apparatus comprising:

a continuous tubular member having an inlet port for receiving a flow of cooking oil and having tubular side sections which are laterally displaced with respect to each other in conformance with the lateral displacement of the interior side surfaces of the fry pot, the tubular side sections being substantially coextensive with the lateral peripheral dimensions of the corresponding fry pot interior side surfaces for permitting nesting engagement of the shower apparatus with the fry pot, each tubular side section having at least one outlet port for discharging a jet of cooking oil into the adjacent interior side surface of the fry pot;
a transverse tubular section interconnecting a pair of the tubular side sections in fluid communication;
and,
a coupling member connected in fluid communication with the transverse tubular section, the coupling member including a rigid body portion and a conduit formed therein, the conduit including an inlet port formed at one end of the coupling member and a laterally projecting flange portion disposed intermediate the inlet port and the transverse tubular member, the inlet port and flange portion being arranged to permit registration of the fluid coupling member with the inlet port concurrently with engagement of the flange portion with the ledge as the shower apparatus inserted into the frypot.
