Starfrost Spiral Freezer 2011

• Rapid freezing of bakery products such as bread, pastries, and cakes.
• Processing of prepared meals, pizzas, and other convenience foods.
• Freezing of various meat, poultry, and fish products.
• Chilling and freezing of fruits, vegetables, and other IQF (Individually Quick Frozen) items.
• Used in large-scale food production for continuous, high-volume freezing.

Typical capacity

For this class of equipment, capacities commonly range from 500 kg/hour to over 3,000 kg/hour, depending on product type and freezing requirements. The seller states approximately 1.2 tonnes per hour for this unit.

Belt width

Commonly found belt widths for spiral freezers are between 500mm and 1,200mm. This unit features a 560mm wide belt.

Number of tiers

Units typically feature between 10 and 40 tiers, influencing the total belt length and dwell time. This unit has 21 tiers.

Product gap

The product gap, or vertical clearance between tiers, commonly ranges from 50mm to 150mm. This unit has a 65mm product gap.

Construction material

Typically constructed from food-grade stainless steel for hygiene and durability, often with plastic or stainless steel belts. This unit features stainless steel construction with a blue Intralox belt.

Power supply

Units commonly require a 400V, 3-phase, 50Hz electrical supply, with varying amperage depending on compressor and fan motor sizes. Buyers should confirm specific power requirements with the seller.

Refrigeration system

Typically designed for use with ammonia (R717) or various HFC refrigerants (e.g., R404A, R507A). The specific refrigerant type and associated compressor package should be confirmed.

Footprint

Despite their high capacity, spiral freezers are designed for a relatively compact footprint compared to linear freezers of equivalent throughput. Dimensions vary significantly based on belt length and tier count.

• What is a spiral freezer used for?

  A spiral freezer is used for continuous, high-volume freezing or chilling of food products, providing a long dwell time in a compact footprint by moving products on a continuous belt in a helical path.

• What maintenance is typically required for a spiral freezer?

• Can this type of freezer handle different product sizes?

• Is this unit suitable for IQF products?

• What are the typical installation requirements?

• How efficient are spiral freezers?

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.
