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.
