ABSTRACT:
A rack-type high capacity warewashing machine is designed to cleanse and sanitize foodware in a cycle time of the order of one minute and to accomplish sanitizing by heating the foodware with fresh hot water sufficiently to kill residual bacteria thereon. The method of operation of the machine includes a final rinse period in which fresh water at a temperature of at least 180.degree. F. (82.22.degree. C.) is sprayed over the foodware to remove residual soil and to heat the foodware surfaces to at least 160.degree. F. (71.11.degree. C.), followed by a dwell period in which the wet heated foodware is maintained in a substantially closed humid atmosphere to prolong the time during which the foodware surfaces remain above bacteria killing temperature and to cause a build-up of Heat Unit Equivalents to at least 3600.
