Abstract
The invention is directed to a method and assembly for sanitizing foodware in a sanitizing zone of a high temperature warewashing machine. The method comprises providing a source of fluid sanitizing material that is effective to sanitize foodware and sensing the temperature of final rinse water being used to sanitize foodware disposed within the sanitizing zone during a final rinse operation of the warewashing machine. An actuating signal is produced when a sensed temperature of the final rinse water is outside the preselected sanitizing temperature range. A sufficient amount of the fluid chemical sanitizing material is then provided in the final rinse water to sanitize foodware disposed in the sanitizing zone when the sensed temperature of the final rinse water is outside a preselected sanitizing temperature range. The specific embodiment is directed to a warewashing pot and pan sink assembly.
