Abstract
An ice-making machine includes an ice-forming mold in a food zone of the ice-making machine; a refrigeration system including a compressor, a condenser, an expansion device, and an evaporator in thermal contact with said ice-forming mold, thus producing a combined evaporator and ice-forming mold; and a bulkhead wall separating an equipment compartment from the food zone. A bulkhead space is located between the bulkhead wall and the combined evaporator and ice-forming mold. The bulkhead space is part of the food zone. Air in contact with ice being formed by the ice-making machine can circulate to the bulkhead space. A source of antimicrobially active gas and an air circulation system that causes the antimicrobially active gas to circulate through the bulkhead space. In use, the antimicrobially active gas flows though the bulkhead space to thereby distribute the antimicrobially active gas throughout the bulkhead space, thus inhibiting growth of microbiological contaminates.
