Starfrost Tunnel Freezer

• Freezing of individual quick frozen (IQF) fish fillets, poultry pieces, and seafood.
• Processing of fruits and vegetables, maintaining individual piece integrity.
• Freezing of bakery products and pasta.
• Glazing of frozen products to prevent dehydration and improve presentation.

Typical capacity

For this class of hybrid tunnel freezer, capacities commonly range from 300 kg/hr to over 1000 kg/hr, depending on product type and freezing requirements.

Footprint

Tunnel freezers typically require a significant linear footprint, with lengths commonly ranging from 8 to 20 metres for industrial units.

Belt width

Belt widths for industrial tunnel freezers are commonly 800mm to 1200mm, influencing throughput and product size.

Power supply

Units of this type typically require a 3-phase industrial power supply, commonly 400V, 50Hz, with significant power draw for refrigeration compressors and motors.

Refrigerant

Modern industrial freezers commonly utilise refrigerants such as ammonia (NH3) or CO2, though some older units may use HFCs.

Construction materials

Components in contact with food are typically stainless steel (e.g., evaporator, belts), with insulated panels for the tunnel structure.

• What is a hybrid tunnel freezer?

  A hybrid tunnel freezer combines different freezing technologies, such as impingement and fluidised bed, to optimise freezing efficiency and product quality for various items.

• What are the benefits of a multi-tier belt system?

• What is a glazing system used for?

• What maintenance is typically required for a tunnel freezer?

• Can this type of freezer handle different product sizes?

IQF systems are highly regarded in food processing for their ability to freeze individual products uniformly whilst maintaining quality and texture. Buyers typically value machines with reliable refrigeration components and consistent belt speed control. When purchasing used equipment, inspecting freezing chamber condition, verifying temperature consistency, and checking refrigerant integrity are essential. Industry users appreciate their efficiency in handling delicate items and relatively low maintenance demands compared to alternative freezing methods.
