Liquid nitrogen systems offer a cost-effective alternative to traditional methods of food freezing and chilling - processing larger quantities faster, while occupying significantly less floor space. Available in a range of sizes, our systems are flexible enough to fit easily into existing production systems with a minimum of capital expenditure.

Tunnel Freezing and Chilling ("Inline" or "Continuous Process")

Tunnel freezers are the mainstay of our liquid Nitrogen systems. First introduced in 1965, the CRYO-QUICK™ tunnel range has a solution for all your production needs. It includes tunnels designed for stand-alone use or for integration into systems incorporating immersion freezers or other equipment from the growing family of CRYO-QUICK™ freezing systems.

Products typically frozen in tunnels are meat cuts, burgers, fish fillets, poultry products, seafood, bakery products, ice cream, appetizers, ethnic foods and ready meals.

Cryo-Quick®Z - Freezing's new frontier

Our revolutionary Cryo-Quick®Z tunnel offers 50% increase in food throughput capacity, up to 25% less liquid nitrogen consumption and significantly improved food quality. Combining two freezing technologies - the application of liquid nitrogen with indirect heat transfer - Cryo-Quick® Z can reduce typical variable costs between 10 and 15%.

Batch processing is the perfect solution for fast economic freezing or chilling of foods. Air Products has designed cabinet freezers to meet the stringent demand of cook-chill and cook-freeze processes.

These extremely flexible systems are ideal for food processors with batch or low volume freezing and chilling requirements.
