Abstract
A system and method for pasteurizing the surface of a food product includes a flame pasteurizing means arranged to transfer heat to an outer layer of the food product as it is carried by a cook belt. The flame pasteurizing means provides a medium that engulfs more than 50% of the surface area of the skin or outer layer and raises the temperature of the outer layer to at least 145° F. (about 62.8° C.). A washing means, arranged at an exit point of the flame pasteurizing means, removes the raised temperature outer layer and stops heat transfer to an adjacent inner layer of the food product. The pasteurized and washed product retains the same color and flavor as that of the unpasteurized product.
