Dorin - Blast Freezer Pack

• Rapid freezing of food products such as meat, fish, and baked goods to preserve quality and extend shelf life.
• Quickly bringing down the temperature of prepared meals and ingredients in catering and food service operations.
• Freezing of pharmaceutical products and other temperature-sensitive goods requiring rapid cooling.
• Batch freezing of various items in industrial processing lines where speed is critical.

Typical capacity

For this class of equipment, blast freezers are designed for rapid temperature reduction, often handling batches from several hundred kilograms up to several tonnes, depending on product and cycle time.

Power supply

Industrial blast freezers commonly require a 3-phase electrical supply, typically 400V/50Hz in the UK, with significant amperage requirements for compressors and fans.

Refrigerant type

Units of this type commonly use HFC refrigerants (such as Freon, a brand name for various refrigerants) or increasingly natural refrigerants, depending on the system's age and design.

Temperature range

Blast freezers are typically capable of reaching temperatures as low as -35°C to -40°C, ensuring rapid freezing.

Footprint

A 'pack' system with separate evaporators, compressor, and condenser offers flexibility in installation, but the combined components can require a substantial plant room or outdoor space for the condenser.

Evaporator configuration

Large floor-mounted evaporators with multiple fans are common for high-airflow requirements in blast freezing rooms, ensuring even temperature distribution and rapid heat extraction.

• What is included in a 'Blast Freezer Pack'?

  A 'Blast Freezer Pack' typically comprises the main refrigeration components: evaporators (inside the freezer room), a compressor (the heart of the refrigeration cycle), and a condenser (which dissipates heat, usually located outdoors).

• Can this unit be used for a different room size?

• What does 'Freon' mean in this context?

• Are the sliding doors included with the refrigeration equipment?

• What is the significance of the 'Heating and Cooling Coils, yr 2000'?

• What are the 'two small evaps 4 fan for chiller room (searle)'?

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.
