<p>A filtering appliance for cleaning cooking oil in a food fryer is designed and dimensioned for single-handed portable use in "hand-gun" fashion. The appliance has an elongate casing means (10) with a hand grip (14) at one end adjacent a pump-and-motor assembly (21, 34). An intake nozzle (11) conducts oil to be cleaned to a cartridge style filter (29) made by stacking annular elements (30, 31) cut from a commercially available filter material of fibrous mat forming a matrix holding particulate filtering media. The filter (29) is axially spring loaded to accommodate yielding of the filter material. The appliance discharges into the food fryer through a duct (15) outside the casing means (10). Thus, the oil is re-circulated to achieve cleaning.</p> |
