Linde Cryoflex CTFA4-60 Cryogenic Freezer

• Rapid freezing of delicate food products such as berries, prawns, or prepared meals.
• Achieving individual quick freezing (IQF) for improved product quality and separation.
• Cryogenic treatment of small industrial parts like springs, nuts, and bolts to enhance material properties.
• Integration into continuous production lines requiring rapid sub-zero processing.

Typical throughput

Varies significantly based on product type and desired temperature, but units of this class are designed for continuous high-volume processing.

Operating temperature range

Typically from ambient down to -110°C or lower, utilising liquid nitrogen or carbon dioxide.

Conveyor belt material

Commonly stainless steel mesh, suitable for cryogenic temperatures and food contact.

Power supply

Typically 3-phase electrical supply for controls and conveyor drive; cryogenic gas supply (liquid nitrogen or CO2) is the primary energy input for cooling.

Footprint

Tunnel freezers of this type require a significant linear space, with the belt length being a primary dimension.

Refrigerant

Designed for use with cryogenic gases such as liquid nitrogen (LIN) or liquid carbon dioxide (LCO2).

• What are the main advantages of a cryogenic freezer over mechanical refrigeration?

  Cryogenic freezers offer significantly faster freezing rates, which helps preserve product quality, texture, and moisture content. They also typically have a smaller footprint for equivalent throughput and offer greater operational flexibility.

• What type of products are best suited for IQF cryogenic freezing?

• What are the primary running costs for a cryogenic freezer?

• Is special ventilation required for a cryogenic freezer?

• Can this type of freezer be used for non-food applications?

Blast freezers hold strong reputations for reliable performance in food processing operations. Buyers typically prioritise units with sturdy construction and consistent temperature control, as these directly affect product quality and shelf life. When purchasing used equipment, inspecting refrigeration systems, door seals and internal surfaces for wear is essential. Industry sentiment favours models from established manufacturers known for durability. Key strengths include rapid freezing capability, energy efficiency compared to older freezing methods, and adaptability to various food types. Proper maintenance history significantly influences buyer confidence in used units.
