Koppens SVR400 Spiral Freezer

• Freezing of bakery products such as bread, pastries, and cakes.
• Rapid freezing of prepared meals and convenience foods.
• Processing of poultry, meat, and fish products to extend shelf life.
• Freezing of fruits, vegetables, and other IQF (Individually Quick Frozen) items.
• Chilling and freezing of dairy products like ice cream and desserts.

Typical capacity

Throughput varies significantly based on product type, temperature, and dwell time, but units of this class are designed for continuous high-volume freezing.

Power supply

Typically requires a three-phase industrial electrical supply, commonly 400V/50Hz in the UK, with specific amperage requirements for the compressor and motors.

Refrigeration system

Units often integrate or are supplied with a dedicated refrigeration plant, commonly using refrigerants like Freon 507 or similar HFCs, or sometimes ammonia for larger industrial applications.

Belt width

Commonly features belt widths ranging from 400mm to over 1000mm, influencing product throughput and size compatibility.

Number of tiers

Spiral freezers typically have multiple tiers (e.g., 10 to 20), maximising freezing capacity within a compact footprint.

Product gap

The vertical product gap between tiers commonly ranges from 50mm to 150mm, determining the maximum height of products that can be processed.

Footprint

While offering high capacity, spiral freezers are designed to be space-efficient, with a relatively compact footprint for their output, often requiring a dedicated area for installation.

• What are the main advantages of a spiral freezer?

  Spiral freezers offer continuous, high-volume freezing in a compact footprint, making them highly efficient for industrial production lines. They are versatile for various product types and sizes.

• What maintenance is typically required for a spiral freezer?

• Can this type of freezer handle different product types?

• What are the common refrigeration types used with these units?

• 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.
