Patent ID: 7681411

Claim:
A sanitary ice making system comprising: a sump pump with an internal impeller for drawing a vacuum, the pump having volute shaped inlet and an outlet; a sump pit holding a supply of water, the inlet of the pump being located within the sump pit and beneath the water line, whereby water is drawn into the inlet of the pump; an aspirating injector located immediately below the inlet of the pump; an ozone generator for generating a supply of ozone gas, an ozone transfer line interconnecting the ozone generator to the aspirating injector, a flow restrictor located along the length of the ozone transfer line for regulating the flow of ozone, whereby ozone is delivered from the ozone generator to the volute shaped inlet of pump via the aspirating injector such that ozone becomes entrained within water being drawn into the inlet of pump; an evaporator employed in creating ice; a water recirculation line coupled to the outlet of the pump, the water recirculation line routing ozonated water from the outlet of the pump and over the evaporator whereby the ozonated water is used in the formation of ice.
