ABSTRACT:
A low temperature conveyor rack-type dishwasher in which the ware-carrying racks are step-wise advanced through a scrapper module, a ware washing module and a rinsing and sanitizing module. The rinsing module has two compartments. In the first compartment fresh hot water at 140.degree. F., is sprayed onto the ware to wash off the detergent from the wash water. In the second rinsing compartment a predetermined volume of sodium hypochlorite is mixed with fresh hot water at 140.degree. F., for rinsing and sanitizing the ware. A tank is provided under each rinse compartment and the overflow from the second compartment is fed into the tank of the first compartment and the overflow from this tank is conveyed back to the scrapper to remove food soil from the screens in that module and to add fresh hot water to the tank underlying the scrapper.
