Frigoscandia GC 76

• Freezing of bakery products such as bread, pastries, and cakes.
• Processing of poultry, meat, and fish products.
• Freezing of prepared meals and ready-to-eat convenience foods.
• Handling of fruits, vegetables, and other delicate food items.
• Blast freezing of dairy products like ice cream and desserts.

Typical throughput

For this class of equipment, throughput can vary significantly, typically ranging from 500 kg/h to several tonnes per hour, depending on product type and desired freezing time.

Footprint

Spiral freezers like the GC 76 are designed for high capacity in a compact area. The exact footprint depends on the number of tiers and belt length, but they commonly require a substantial floor area and significant headroom.

Refrigerant type

Units of this type commonly utilise ammonia (R717) due to its high efficiency and environmental profile, as specified for this unit, or sometimes CO2 (R744).

Belt width

The '76' in the model name often refers to the belt width in inches, meaning approximately 1.9 metres, which is a common size for industrial spiral freezers.

Operating temperature

Typically operates at temperatures between -30°C and -40°C to achieve rapid freezing.

Construction material

The freezing tunnel and belt are typically constructed from food-grade stainless steel for hygiene and durability.

Power supply

Industrial units of this size commonly require a 400V, 3-phase, 50Hz electrical supply, with power consumption varying based on compressor size and operational load.

• What is an 'expanding belt' system?

  An expanding belt system, such as Frigoscandia's GyroStack, allows the belt to expand and contract as it moves through the spiral, preventing product damage and optimising space utilisation within the freezer.

• What are the benefits of a water belt washing system?

• Is R717 (NH3) refrigerant safe for food processing?

• What maintenance is typically required for a spiral freezer?

• Can this freezer handle different product types?

Spiral freezers are valued in food processing for their compact footprint and efficient product handling. Buyers typically appreciate their gentle freezing action, which preserves product quality and texture. When purchasing used equipment, inspection of the spiral belt condition and refrigeration system performance is essential. The stainless steel construction generally resists corrosion well in demanding environments. Common considerations include maintenance costs and spare parts availability, though reliability across production runs remains a noted strength.
