Zusammenfassung:	An improved method and apparatus for pasteurizing filled food containers having contents to be pasteurized includes spraying a heat transfer fluid onto the containers. As the contents increase in temperature, the flow rate of heat transfer fluid is decreased. The heat transfer fluid is at least about 20° F. hotter than the initial average temperature of the contents. In one embodiment, the temperature of the spent heat transfer fluid typically does not vary more than about 6° F. to 9° F.
