Patent ID: 10300161

Abstract:
An ice maker includes an ice making unit comprising an evaporator connected to a refrigeration system, an ice holding bin, a sump, a pump, a drain valve, an ozonated water source, and a controller. The controller activates the ozonated water source supplying a first volume of ozonated water to the sump, thereafter activates the pump to circulate the first volume of ozonated water from the sump to the ice making unit, once a predetermined sterilization time has been reached, the controller turns off the pump and drains the first volume of ozonated water from the sump. The controller initiates an ice making mode, and activates the ozonated water source to supply a second volume of ozonated water to the sump, thereafter activates the pump to circulate the second volume of ozonated water from the sump to the ice making unit forming ozonated ice on the evaporator, and initiates an ice harvest mode to remove the ozonated ice from the evaporator and delivers it to the ice holding bin.
