Cryogenic freezing

For cryogenic freezing, nitrogen is used in several forms—as a shower of liquid droplets, as a liquid bath for direct immersion, or as a cold gas. Carbon dioxide is used as a liquid or in solid snow" form. When used in a tunnel for 1QR applications, liquid carbon dioxide can freeze products at a temperature from -62 lo -78°C (-80 to 109°F). Fluorocarbons and halocarbons also have been used in conjunction with tunnel and spiral-type freezers thill are used in IQF methods. [Pg.685]
