Various - BLAST FREEZER - 400m³

• Rapidly freezing large quantities of food products to preserve quality and extend shelf life.
• Quickly chilling or freezing prepared meals, baked goods, and confectionery items.
• Used in large-scale food processing, cold storage, and logistics operations.
• Freezing seafood, meat, and poultry products immediately after processing.
• Suitable for pharmaceutical or chemical processes requiring rapid temperature reduction.

Typical capacity

This unit is described as 400m³, indicating a substantial volume for high-throughput freezing operations. Buyers should confirm the exact usable internal dimensions.

Compressor type

Units of this class commonly feature robust industrial-grade compressor packs, such as the GEA Grasso twin compressor mentioned, designed for continuous operation.

Condenser type

Industrial blast freezers typically utilise high-capacity condensers, like the Baltimore VXC-185, to efficiently dissipate heat.

Refrigerant

The specific refrigerant used would need to be confirmed with the seller, but industrial systems commonly use ammonia (R717) or HFC/HFO blends.

Power supply

For this class of equipment, a three-phase industrial power supply (e.g., 400V, 50Hz) is typically required. Exact power consumption will vary.

Safety features

Advanced units often include integrated safety systems, such as the TYCO Nitrogen sprinkler system mentioned, for fire suppression.

Control system

Complete control panels and switchgear are standard for managing temperature, cycle times, and safety protocols.

• What is the typical footprint required for a blast freezer of this size?

  A 400m³ blast freezer will require a significant footprint, not only for the chamber itself but also for the external compressor pack, condenser, and associated pipework. Buyers should request detailed layout drawings.

• What kind of ongoing maintenance is typically involved?

• Can this unit be relocated?

• What are the typical installation requirements?

• Is specialist training required to operate this equipment?

Blast freezers hold strong reputations for reliable performance in food processing operations. Buyers typically prioritise units with sturdy construction and consistent temperature control, as these directly affect product quality and shelf life. When purchasing used equipment, inspecting refrigeration systems, door seals and internal surfaces for wear is essential. Industry sentiment favours models from established manufacturers known for durability. Key strengths include rapid freezing capability, energy efficiency compared to older freezing methods, and adaptability to various food types. Proper maintenance history significantly influences buyer confidence in used units.
