Ribbon-freezing method and apparatus

摘要

A method and apparatus for improved control of ice-crystal formation in solid and semi-solid organic materials during freezing in a bath containing a cruciferous-oil slush is disclosed. Ribbon racks are used both to separate the items being frozen from each other and to efficiently distribute the items across the bath. This separation and distribution of the items in a ribbon improves control of the rate of freezing by preventing brine shock when the items are immersed in the brine and preventing cumulative localized thermal exhaustion during the freezing process. The ribbon rack freezing apparatus is adjustable to accommodate the variations in dwell times and flow rates required by different materials.
