Frigoscandia Midget Spiral Freezer

• Freezing of bakery products such as pastries, bread rolls, and cakes.
• Rapid freezing of prepared meals and ready-to-eat food items.
• Processing of poultry, meat, and fish products for extended shelf life.
• Freezing of fruits and vegetables, maintaining texture and nutritional value.
• Chilling and freezing of dairy products like ice cream and desserts.

Typical capacity

For this class of equipment, capacities commonly range from 500 kg/hr to 1500 kg/hr, depending on product type and freezing requirements. This specific unit is advertised at approximately 600 kg/hr.

Power supply

Spiral freezers typically require a 3-phase industrial power supply, commonly 400V/50Hz in the UK, with varying amperage requirements based on compressor size and motor load.

Refrigerant type

Units of this type commonly utilise refrigerants such as Ammonia (NH3) or various HFCs (e.g., R404A, R507). Buyers should confirm the specific refrigerant used in this unit.

Belt width and tiers

Effective belt widths for midget spiral freezers are typically in the range of 300mm to 600mm, with the number of tiers varying to achieve desired dwell times. This unit features an 18-tier configuration with a 355mm effective belt width.

Product gap

The product gap, which dictates the maximum product height, is commonly around 40mm to 60mm for this type of freezer. This unit offers a 45mm product gap.

Footprint

Skid-mounted spiral freezers are designed for a relatively compact footprint compared to linear freezers of similar capacity, though exact dimensions vary significantly by model and tier configuration. Buyers should request specific dimensions for installation planning.

Construction material

The freezing tunnel and belt are typically constructed from food-grade stainless steel for hygiene and durability, with insulation panels commonly made from insulated composite materials.

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

  Regular maintenance includes belt cleaning and tensioning, inspection of refrigeration components, motor and gearbox checks, and ensuring proper insulation integrity. Gaskets and seals should also be periodically inspected and replaced as needed.

• Can this freezer be used for different products?

• What are the typical installation requirements?

• How does a 'skid-mounted in cabinet' design benefit operation?

• What should I consider regarding the 'compressor pack' being included?

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.
