Deep fat fryer
Abstract
Abstract A DEEP FAT FRYING UNIT HAVING A GLASS COOKING VESSEL ADAPTED TO HOLD A SUPPLY OF COOKING OIL. THE UNIT IS HEATED BY AN ANNULAR INFRARED RADIANT GAS BURNER ASSEMBLY WHICH HEATS THE OIL PRIMARILY BY INFRARED RADIATION PASSING FROM THE BURNER ASSEMBLY DIRECTLY THROUGH THE VESSEL WALL. THE BURNER ASSEMBLY IS ABOVE THE BOTTOM OF THE VESSEL SO THAT THERE IS A COOL ZONE AT THE BOTTOM OF THE VESSEL WHICH ELIMINATES BURNING FOOD SEDIMENT DEPOSITED THEREIN. THE RADIANT HEAT IS ABSORBED BY THE OIL IN AN ANNULAR ZONE ADJACENT THE VESSEL WALL AND THIS PRODUCES OIL CIRCULATION BY CONVECTION UPWARDLY ALONG THE WALL AND DOWNWARDLY AT THE CENTER OF THE VESSEL, BUT WITHOUT OVERHEATING THE OIL.
