Abstract
Abstract A DEEP FAT FRYER COMPOSED OF A FRYING VESSEL HAVING SIDE AND BOTTOM WALLS AND A HOOD. AN EXTERNAL HEAT EXCHANGER AND PUMP ARE CONNECTED TO THE VESSEL FOR HEATING THE FAT AND PASSING IT THROUGH THE VESSEL. A PROVISION IS MADE FOR INTRODUCING A SMALL AMOUNT OF MOISTURE INTO THE FAT AT THE POINT WHERE THE FAT ENTERS THE VESSEL TO DISTILL OFF UNDESIRED FAT BREAKDOWN PRODUCTS, THE MOISTURE IS PREFERABLY INTRODUCED AS STEAM THROUGH A MANIFOLD LOCATED AT THE INLET END OF THE FRYING VESSEL. AS THE STEAM ESCAPES, IT CARRIES AWAY THE PRODUCTS OF FAT DEGRADATION AND AT THE SAME TIME FILLS THE HOOD THUS LESSENING OXIDATION THAT WOULD OTHERWISE OCCUR ON THE SURFACE OF THE FAT.
