Koppens CFS 600mm Spiral Freezer

• Rapid freezing of bakery products such as bread, pastries, and cakes.
• Processing of prepared meals, including ready meals and individual components.
• Freezing of various meat, poultry, and fish products.
• Handling of fruits and vegetables, both whole and processed.
• Suitable for high-volume production lines requiring continuous freezing.

Typical capacity

For a 600mm belt and 19 tiers, throughput can typically range from 500 kg/hr to over 2000 kg/hr, depending on product type, temperature, and dwell time.

Power supply

Units of this class commonly require a 3-phase electrical supply, typically 400V, 50Hz, with varying amperage depending on motor sizes and auxiliary components.

Refrigerant compatibility

This unit was last used with ammonia, which is common for industrial freezers due to its efficiency. Other refrigerants may be compatible with appropriate modifications.

Product gap

A 90mm product gap is suitable for a wide range of products, from relatively flat items to moderately sized bulk goods.

Construction material

All stainless steel construction is standard for food processing equipment, ensuring hygiene, durability, and corrosion resistance.

Footprint

Spiral freezers, while efficient in their use of vertical space, typically require a significant floor area, which varies with the number of tiers and belt length.

Maintenance requirements

Regular cleaning, belt inspection, and lubrication of moving parts are typically required to maintain optimal performance and hygiene.

• What does 'without refrigeration plant' mean?

  This means the freezer unit itself is offered, but the external compressor, condenser, and associated pipework for generating the cold are not included. Buyers will need to source or integrate their own refrigeration system.

• Is a brand new belt a significant advantage?

• Can this freezer be used with refrigerants other than ammonia?

• What kind of products is a 600mm wide belt suitable for?

• 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.
