BOX-TYPE WAREWASHER INCLUDING HEAT RECOVERY SYSTEM FOR REDUCING AIR MOISTURE LEVEL AT THE END OF CYCLE

摘要

A box-type warewasher (10) includes a housing defining an internal treatment space (14) for receiving wares to be washed and a liquid sump (16) below the treatment space. A wash liquid delivery system includes a wash pump (18) having an input connected to the liquid sump and an output connected to deliver liquid to one or more spray nozzles (26) of the treatment space. A rinse liquid delivery system includes a rinse pump (24) for delivering rinse water to one or more spray nozzles (26) of the treatment space. A condensing system includes a heat exchanger exter-nal of the treatment space, and a blower (34) for moving hot moist air from the treatment space across the heat exchanger and back to the treat-ment space. A controller effects operation of each of the wash liquid deliv-ery system, the rinse liquid deliver system and the condensing system. The controller is configured for carrying out at least one ware cleaning se-quence in which: a wash spray operation is carried out by operating the wash pump,- subsequent to the wash spray operation a rinse spray opera-tion is carried out by operating the rinse pump,- and subsequent to the rinse spray operation a condensing operation is carried out by operating the blower.
