Freezing equipment

Linde has for many years been actively involved in developing cryogenic freezing technologies

Our numerous freezers meet the needs of a variety of applications. Modern freezer designs use the latest control programs to increase efficiency while meeting stringent hygiene standards.

The Linde CRYOLINE® Family

Cryogenic freezing and cooling of foodstuffs using liquid nitrogen and carbon dioxide is a well established technology that has been enhancing food processing for many years. The CRYOLINE® family of food chilling equipment meets these modern requirements. To see what will work best for you, please review the information contained in the specific food product or freezer pages.

Advantages of cryogenic freezers:

• Fast in-line freezing and cooling, thus preserving flavour
• Higher quality of the frozen product compared with slower methods
• Reduced drip loss on defrosting
• Less dehydration resulting in a higher yield
• Lower space requirements
• Different types of freezers available to suit the requirements of different foodstuffs

Equipment benefits:

• Most equipment delivered 'ready to run'
• Only a few days generally needed to install equipment
• Most standard equipment available off the shelf
• Standard equipment is available for rent or sale in most countries
• Low maintenance design
• The equipment is easy to use and requires no special knowledge
• Training for key staff given on start up

CRYOLINE® CF

The CRYOLINE® CF is a cryogenic food cabinet freezer, suitable for small batch operations where food trolleys are manually loaded.

It provides great flexibility for a variety of food products as well as short and long retention times. The freezer is available in several models and sizes and can operate with liquid nitrogen (LIN) or carbon dioxide (LIC).

CRYOLINE® CS

The CRYOLINE® CS is a cryogenic self-stacking spiral freezer. Providing a high production capacity within a small space, it is suitable for a wide range of food products.

The CRYOLINE CS is targeted at medium volume customers with typical achievable production rates of 1,200–2,400 kg/h (2,600–5,300 lb/h)*.

CRYOLINE® CW

Easily switching between IQF (individually quick frozen) mode and standard flat belt tunnel freezer, the CRYOLINE® CW is a versatile multi-purpose cryogenic freezer.

It utilises the CRYOWAVE controllable vibration technology that provides adjustable agitation for optimum IQF foods, while also providing the ability to perform as a standard tunnel for many other food types of differing shapes and sizes. The freezer is available in various models and belt widths with typical achievable production rates of 500–2,700 kg/h (1,100–6,000 lb/h)*.

CRYOLINE® MT

The CRYOLINE® MT is an in-line continuous tunnel freezer, which uses either liquid nitrogen (LIN) or carbon dioxide (LIC), depending on your food product and production needs.

It is modular in design, enabling you to expand production by adding additional tunnels for a longer freezing production line. It is available in several models and belt widths with production rates of 200–2,500 kg/h (440–5,500 lb/h)*.

CRYOLINE® PE

This is the only cryogenic freezer designed to produce formed food shapes. Processors interested in portion control of frozen ingredients for sauces, purees, soups and other liquid food products can achieve weight proportioning and unique logo imprints.

The CRYOLINE® PE is perfectly suited for processors servicing the food service and ready meals industries as well as consumer markets.

CRYOLINE® SC

For products which are difficult to handle, the CRYOLINE® SC in-line tunnel freezer uses a patented disposable foil belt. The unit can easily freeze or cool liquid and/or marinated products, or alternatively harden soft products (e. g. fillets of fish or chicken) prior to final freezing.

Because the belt is disposable, it is possible to change products during the production cycle without having to clean the belt. Another advantage over mesh belts is that the foil is smooth, which is perfect for processing soft foodstuffs as it ensures no belt marks.

CRYOLINE® SI

The CRYOLINE® SI is a nitrogen immersion freezer that conveys the food product through a nitrogen bath for quick IQF freezing. It is designed for high-volume IQF (individually quick frozen) applications, such as cooked poultry, diced meats and prawns.

Immersion freezers expose the product directly to liquid nitrogen to get a rapid crust freeze to lock in product yield and reduce cooking losses. This ensures that there is little clumping and that only a few product particles stick to each other and the belt.

CRYOLINE® TI

The CRYOLINE® TI is a high performance freezer utilising top-down impingement technology. This modular flat belt freezer delivers more than twice the heat transfer rate of standard tunnel freezers and reduces the required footprint by 40 %.

Using liquid nitrogen (LIN) as a cooling agent, CRYOLINE TI is suitable for a wide range of non-IQF products with a typical capacity range of 1,500–2,500 kg/h (3,300–5,500 lb/h)*.

CRYOLINE® XF

The CRYOLINE® XF is built for large capacities from 2,500 to 7,500 kg/h (5,500-16,500 lb/h)*. Its patented technology delivers twice the heat transfer rate of commercial spiral freezers, making it twice as powerful.

The CRYOLINE XF provides a smaller footprint, a higher production capacity and is more efficient than standard cryogenic spiral freezers. It is suitable for high temperature and high moisture products, e. g. cooked poultry, seafood and prepared meals.
