Frigoscandia GC42 Spiral Freezer

• Rapid freezing of bakery products such as bread, pastries, and cakes.
• Efficient freezing of prepared meals, pizzas, and ready-to-eat items.
• Preservation of seafood, including fish fillets, shrimp, and shellfish.
• Freezing of poultry products like chicken pieces, nuggets, and formed items.
• Processing of fruits and vegetables, maintaining texture and nutritional value.

Typical capacity

For this class of equipment, capacities typically range from 500 kg/hr to several tonnes/hr, depending on product type and desired freezing time.

Power supply

Units of this type commonly require a 400V, 3-phase, 50Hz electrical supply, with varying amperage requirements based on compressor and fan motor sizes.

Refrigeration system

Typically designed for use with ammonia (NH3) or various freon refrigerants, requiring an external refrigeration plant.

Belt width

Effective belt widths for Frigoscandia spiral freezers commonly range from 300mm to over 1000mm, influencing throughput.

Product gap

Maximum product gaps on units of this type typically range from 40mm to 100mm, accommodating various product heights.

Footprint

Spiral freezers are designed for a compact footprint relative to their belt length, but still require significant floor space and height clearance.

Construction material

Generally constructed from stainless steel for hygiene and durability in food processing environments.

• What maintenance is typically required for a used spiral freezer?

  Regular maintenance typically includes belt cleaning and tensioning, inspection of evaporator coils, fan motors, and bearings, and checking the refrigeration system for leaks and efficiency. A pre-purchase inspection is recommended.

• Can this type of freezer be reconfigured for different products?

• What are the typical installation requirements?

• How efficient are older spiral freezers compared to new models?

• What is meant by 'North-South belt configuration'?

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.
