ABSTRACT:
A warewasher such as a domestic dishwashing machine has a first recirculating path for recirculating wash and rinse fluids through nozzles which spray the fluid onto food ware items in the wash chamber of the warewasher. Fluid is also circulated from the wash chamber through a soil collecting circuit which conducts fluid to a soil collector where soil is filtered from the fluid before it is returned to the wash chamber. The soil collector quickly removes food soil debris from the fluid on its first passage through the soil collecting circuit and holds it for discharge into the warewasher drain system when the fluids are subsequently drained from the warewasher. A drain pump impeller is used to perform the dual functions of draining liquid from the chamber and recirculating fluid through the soil collecting circuit. In its preferred form, liquid passing through the first recirculating path is preliminarily filtered thereby preventing soil particles from being recirculated and redeposited onto the food ware items. In such preferred form of warewasher, soil removed from the ware can only enter the soil collecting circuit, and by being captured on its initial pass, is prevented from being reduced in particle size, thus minimizing turbidity of the water.
