Frigoscandia GC51 Spiral Freezer

• Freezing prepared meals and ready-to-eat products.
• Processing poultry, meat, and seafood items.
• Handling bakery products such as bread, pastries, and desserts.
• Freezing fruits, vegetables, and other IQF (Individually Quick Frozen) goods.
• Used in large-scale food production lines requiring continuous freezing.

Typical capacity

For this class of equipment, throughput can range from 500 kg/hr to several tonnes/hr, depending on product type and freezing requirements.

Power supply

Commonly requires a 3-phase industrial electrical supply, typically 400V, 50Hz, with significant power draw for refrigeration compressors and motors.

Refrigerant type

Units of this vintage typically used refrigerants such as R22, though many have been retrofitted to more modern, environmentally compliant alternatives like ammonia (NH3) or CO2.

Footprint

Spiral freezers require substantial floor space and significant vertical clearance due to their multi-tier design; exact dimensions vary by configuration.

Belt width

Units like the GC51 commonly feature belt widths around 500mm, suitable for a variety of product sizes.

Maintenance

Regular maintenance is crucial, including belt cleaning, refrigeration system checks, and component lubrication, often facilitated by features like belt wash and hot gas defrost.

Temperature range

Typically operates at freezing temperatures down to -35°C to -40°C in the freezer chamber.

• What are the benefits of a spiral freezer?

  Spiral freezers offer continuous, high-volume freezing in a compact footprint, making them efficient for production lines requiring significant throughput while maintaining product quality.

• What is hot gas defrost?

• Why is a belt wash system important?

• Can this type of freezer handle different product types?

• What should I consider regarding installation?

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.
