What are the advantages of an ammonia-based spiral freezer?

Ammonia is a highly efficient refrigerant, offering excellent thermodynamic properties and lower operating costs compared to some synthetic refrigerants. It is also environmentally friendly with zero ODP and GWP.

What maintenance is typically required for a spiral freezer?

Regular maintenance includes belt inspection and cleaning, lubrication of moving parts, checking refrigeration system pressures, and general sanitation. Compressor service is also a key aspect.

Can this type of freezer handle different product types?

Yes, spiral freezers are versatile and can handle a wide range of products. The key is adjusting belt speed, temperature, and product gap to suit specific freezing requirements.

What safety considerations are there with an ammonia system?

Ammonia is a toxic and flammable gas, requiring strict safety protocols, leak detection systems, proper ventilation, and trained personnel for operation and maintenance. Compliance with relevant safety standards is crucial.

What is the typical lifespan of a used spiral freezer?

With proper maintenance and refurbishment, a well-built spiral freezer can have a long operational life, often exceeding 15-20 years. The condition of the compressor and belt system are key factors.

Typical Specifications

Typical capacity: Throughput for this class of equipment commonly ranges from 500 kg/hr to several tonnes/hr, depending on product and dwell time.
Power supply: Units of this type typically require a 3-phase industrial power supply, commonly 400V, 50Hz, with significant current draw for refrigeration compressors and motors.
Refrigerant type: This unit uses ammonia (NH3), a common industrial refrigerant known for its efficiency and environmental profile, requiring specific safety protocols.
Belt width: For this category, belt widths typically range from 600mm to 1500mm, influencing product throughput and size.
Product gap: The product gap, or height between tiers, commonly varies from 80mm to 150mm, accommodating different product thicknesses.
Construction material: Spiral freezers for food processing are typically constructed from stainless steel for hygiene and corrosion resistance.
Footprint: The footprint for a spiral freezer can be substantial, often requiring a dedicated area of several square metres, depending on the number of tiers and belt length.
