Crust Freezers

For efficient slicing, the optimal temperature for ham and turkey logs is 21° to 25°F (-6° to -4°C) on the surface and 34°F (1°C) at the core. Unitherm’s patented crust freezing technology optimizes the condition of every log as an inline process.

Our Crust Freezers freeze the surface of every log to your specifications, using either Freon or ammonia at -40°F (-40°C). Our machine is the only vertical Crust Freezer on the market and the only one with a mechanical option, providing you with a powerful solution that’s less expensive, and has a smaller footprint than a traditional nitrogen or CO2 tunnel. This improves profitability and productivity while reducing operating costs.

Unique to the design of our Crust Freezer is a cleaning step that pasteurizes the freezer itself. This sterilization step ensures that the logs aren’t contaminated by particulate during the crusting process.

Our Crust Freezers are custom-built to your specifications.
