Aston Vacuum Cooling Chamber

• Rapid cooling of baked goods to extend shelf life and improve texture.
• Efficiently cooling cooked meats and prepared foods in a controlled environment.
• Pre-cooling fresh produce to reduce spoilage during transport and storage.
• Accelerating the cooling process for various food products post-processing.

Typical capacity

For this class of equipment, chambers can range from small batch units to larger industrial systems, typically accommodating multiple racks or trolleys of product.

Power supply

Commonly found on units of this type, a 3-phase electrical supply (e.g., 400V, 50Hz) is required for the vacuum pump and control systems.

Vacuum pump type

Typically, a robust rotary vane or liquid ring vacuum pump is integrated to achieve the necessary low pressures.

Chamber material

The internal chamber is commonly constructed from food-grade stainless steel for hygiene and durability.

Control system

Units typically feature a PLC-based control system with a user interface for setting vacuum levels, cooling times, and temperature monitoring.

Footprint

The footprint for a vacuum cooling chamber can vary significantly, from compact standalone units to larger walk-in systems, depending on capacity requirements.

• How does vacuum cooling work?

  Vacuum cooling works by rapidly reducing the atmospheric pressure within a sealed chamber, causing water within the product to evaporate at a lower temperature, thus drawing heat away and cooling the product quickly.

• What are the main benefits of vacuum cooling for bakery products?

• Is special training required to operate a vacuum cooling chamber?

• What maintenance is typically involved for this equipment?

• Can this unit be used for products other than bakery items?

Chillers and recirculating coolers are valued for reliable thermal management across industrial and laboratory applications. Buyers typically prioritise units with verifiable maintenance records and minimal corrosion, as cooling system integrity directly impacts performance. Key considerations include refrigerant type compatibility, pump condition, and heat exchanger cleanliness. Industry sentiment reflects strong durability when properly serviced, though used units require thorough pressure testing before deployment. Reputable manufacturers command higher resale value, reflecting confidence in longevity and spare parts availability.
