Food cooking apparatus having continuous cleaning properties and process for producing same

Abstract

Abstract AN IMPROVEMENT IN THE PROCESS FOR PRODUCING AN ADHERENT CERAMIC COATING ON A METAL SUBSTRATE USED IN FOOD COOLING APPARATUS, THE COATING HAVING THE CONTINUOUS CLEANING PROPERTY OF DIMINISHING ACCUMULATION OF CARBONACEOUS RESIDUE WHICH RESULTS FROM THE EXPOSURE TO GREASE SPATTERS AT ORDINARY OPERATING TEMPERATURES, CAN BE EFFECTED BY: APPLYING TO THE SUBSTRATE IN INITIMATE CONTACT WITH EACH OTHER AN ENAMELING COMPOSITION COMPRISING ALKALI-BEARING GLASS FRIT PARTICLES, ABOUT 1/2 TO 25% HALIDE BASIS WEIGHT OF SAID GLASS FRIT, AND ABOUT 2-75 PARTS, PER 100 PARTS OF SOLIDS IN SAID ENAMELING COMPOSITIONS, OF PARTICULATE ELEMENTAL METAL SELECTED FROM THE GROUP CONSISTING OF ALUMINUM, MAGNESIUM, HIGH ALLOYS OF EITHER, AND MIXTURES OF THE SAME; HEATING THE RESULTING DEPOSIT IN A HEATING ZONE UNITL IT FORMS, BY INTERACTION OF THE FRIT AND THE PARTICULATE METAL, AN INTEGRAL, POROUS, SORPTIVE SURFACE STRUCTURE CONTAINING CRYSTALLINE DEVITRIFICATION PRODUCTS; THEN ARRESTING SAID INTERACTION IN A COOLING ZONE BEFORE SUBSTANTIAL COALESCENCE OF THE STRUCTURE OCCURS. COOKING OVEN WALLS, FIXED OR REMOVABLE PANELS, BROILER PANS AND RACKS INCORPORATING THE RESULTING COATED METAL SUBSTRATES CAN BE MADE.
