Advanced - Used Advanced Asfs 13,52-660/2300-200

Applications & Use Cases

• Individually Quick Freezing (IQF) of small to medium-sized food products such as berries, vegetables, and seafood.
• Freezing of bakery items like pastries, bread rolls, and dough.
• Processing of prepared meals, poultry pieces, and meat products to extend shelf life.
• Suitable for high-volume production lines requiring continuous freezing processes.

Typical Specifications

Typical cooling capacity

For this class of equipment, cooling capacities commonly range from 100 kW to over 500 kW, depending on product load and desired temperature.

Refrigerant type

Units of this type commonly utilise ammonia (NH3) due to its high efficiency and environmental profile, though other refrigerants may be found.

Evaporating temperature

Typically, evaporating temperatures for spiral freezers are in the range of -35°C to -45°C to achieve rapid freezing.

Belt width

Commonly, belt widths for industrial spiral freezers range from 600 mm to 1500 mm, influencing throughput.

Product clearance (GAP)

Product gaps are typically between 50 mm and 100 mm, dictating the maximum height of products that can be processed.

Footprint

Spiral freezers require a significant footprint; dimensions commonly vary based on belt length and number of tiers, but will always be substantial.

Power supply

Typically requires a three-phase industrial power supply, commonly 400V, 50Hz, with significant installed power for compressors and motors.

Frequently Asked Questions

• What is IQF freezing?

  IQF stands for Individually Quick Freezing. It's a method where each piece of food is frozen separately, preventing clumping and preserving texture, flavour, and nutritional value.
