Did You Know ... About Crust Freezing?

Cooked and dressed hamburgerQuickly freezing the outer surface of food products - also know as crust freezing - is just the beginning of the cryogenic freezing process for food. This action firms the product surfaces to reduce moisture migration and retain product shape & appearance. The product continues to lose heat and equilibrates to the target temperature. 

The Food Freezing Process in our Food Technology Laboratory
Praxair has performed over 12,000 tests to determine the freezing rate and thermal profile of a wide array of food products in our Food Lab over the last 45 years. We use that experience - stemming from all those analyses - to help improve your product quality and boost production.

Testing your product in our Food Lab is a great way to witness first-hand the benefits of freezing or chilling with liquid nitrogen or liquid carbon dioxide. The lab equipment is full-sized, production level systems – not models nor simulations nor analogs. In the lab, observe the simplicity of operation of our freezer systems, evaluate the quality of the product first hand, and learn about the science behind cryogenics. Download the mailer (325KB)
