Cryogenic tunnel freezers can be used to individually quick freeze (IQF), crust-freeze, or freeze various foods and trayed products with a cryogenic gas in a continuous in-line process. Adjustable, high-speed internal fans, controllable gas injection and exhaust levels optimize the flow of cryogenic gases as foods move through the freezer on a conveyor.

Tunnel freezing is ideal for:

Prepared foods: Trayed foods, ready-to-eat meals, pizzas, stuffed pasta, specialty items, etc.
Baking: Rolls, pies, cookie dough and other dough products
Protein: Marinated chicken and turkey breasts, breaded poultry and fish fillets, burgers, filets and sausages, etc.

Individual Quick Freezing (IQF)

Sliced and diced poultry and beef, scallops, shrimp, pizza toppings; tortellini and other pastas.
