Abstract:
A method for controlling the presence of microbial organisms in the interior of an ice conveyance system which comprises:in said ice conveyance system providing an ice maker, an ice receiver, an enclosed conduit through which ice can be conveyed between said ice maker and said ice receiver, and gas flow means for conveying said ice through said conduit; providing water for said ice maker; injecting ozone into said water; thereafter passing said ozone-containing water to said ice maker and causing said ozone-containing water to freeze within said ice maker to form said ice, such that said ice contains said ozone; and thereafter passing said ice containing said ozone from said ice maker through said conduit to said ice receiver; whereby as said ice resides in or passes through said ice maker, conduit and ice receiver, at least some of said ozone is evolved as gas from said ice cubes and disperses throughout interiors of said ice maker, conduit and ice receiver, therein contacting and killing microbial organisms which are present therein.
