Freezing preserves raw or prepared foods to allow them to be stored for an extended period. Placing food in a frozen state slows decomposition by converting residual moisture to ice, inhibiting the growth of most bacterial species, and locking in important sensory attributes like taste, color and essential nutrients.

The objective of all cryogenic tunnel freezers is to quickly freeze or cool products in an efficient manner using a cryogenic liquid.

Sub-zero treatment of steel can alter the phase structure to help achieve improvements in quality and finished parts performance.

Airgas Inc., Radnor, Pa., discussed the efficiency of its FreezeRight™ IQF cryogenic freezer by processors of individually quick frozen (IQF) products at the Boston International Seafood Show.
