Heinen Spiral Freezer

• Rapid freezing of bakery products such as bread, pastries, and cakes.
• Efficient freezing of prepared meals, pizzas, and convenience foods.
• Processing of various meat, poultry, and fish products.
• Freezing of fruits, vegetables, and other delicate food items.
• Suitable for high-volume production lines requiring continuous freezing.

Typical capacity

For this class of equipment, throughput can range from 500 kg/h to several tonnes per hour, depending on product type and dwell time.

Power supply

Units commonly require a 400V, 3-phase, 50Hz electrical supply, with total power consumption varying based on compressor and fan motor sizes.

Refrigerant type

While this unit was last used on Ammonia, spiral freezers are also commonly configured for refrigerants such as CO2 or Freon, depending on system design.

Product gap

Typically, product gaps for this type of freezer range from 80mm to 150mm, allowing for various product heights.

Belt width

Common belt widths for industrial spiral freezers are between 600mm and 1200mm, influencing overall throughput.

Footprint

The footprint for a spiral freezer can be substantial, typically requiring a floor area of 10m x 10m or more, depending on the drum diameter and number of tiers.

Construction material

Units of this type are almost exclusively constructed from stainless steel for hygiene and durability in food processing environments.

• What are the advantages of a spiral freezer over other freezing methods?

  Spiral freezers offer continuous, high-volume freezing with a compact footprint relative to their capacity. They are efficient for products requiring longer dwell times and provide consistent product quality.

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

• What maintenance is typically required for a spiral freezer?

• Is it possible to change the belt configuration (e.g., North-South to East-West)?

• What are the considerations for installing a used spiral freezer?

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.
