CRYOLINE® SC Super Contact Freezer

It uses a disposable plastic film which acts as the conveyor belt travelling through the freezing tunnel over cryogenically refrigerated plates. These plates operate at -196 °C, rapidly and effectively freezing the contact surface of the product, while the tunnel environment is cryogenically cooled by liquid nitrogen to reduce the entire product temperature.

The consolidated features of this freezer technology deliver products free from belt marks and wrinkles which can be easily handled for further processing. Due to the nature of the belt, soft, wet or sticky products can be managed without product deformation or adhesion – even liquids can be frozen with ease. As the belt is disposable, the freezer can be quickly and efficiently cleaned at the end of production, minimising expensive delays.

Process overview

The CRYOLINE® SC™ is a contact freezer which removes the heat from the product by contact with the cold plates. The gas generated by the vaporisation of the liquid nitrogen is then exhausted to the atmosphere.

As the temperature of the exhaust is controlled, the amount of cold extracted safely from the nitrogen can be optimised according to the production demands. High-speed fans circulate the cold gas atmosphere inside the tunnel and help to freeze the upper surface of the product.

Typical products

• Small or diced product such as pizza topping
• Flat fish
• Marinated or wet products
• Viscous fluids
• Powdered products from hot processes i.e. gravy granules, chocolate powder
• Premium quality products where belt markings may be an issue
