Gronemeyer Spiral Cooler

• Cooling of baked goods such as bread, pastries, and biscuits post-oven.
• Chilling of confectionery products like chocolates and sweets.
• Reducing the temperature of prepared meals and ready-to-eat food items.
• Cooling of packaged goods to extend shelf life or prepare for further processing.
• Temperature reduction for various non-food industrial products requiring controlled cooling.

Typical capacity

Throughput for a twin spiral cooler of this class can vary significantly, often ranging from 500 kg/hr to several tonnes/hr, depending on product and cooling requirements.

Power supply

Units of this type commonly require a 3-phase industrial power supply, typically 400V, 50Hz, with varying amperage based on motor and refrigeration load.

Footprint

Spiral coolers are designed for compact cooling, but a twin-drum system will require a substantial floor area and significant headroom, typically several metres in height.

Belt width

Common belt widths for industrial spiral coolers range from 150mm to over 1000mm, influencing product size and throughput.

Tier count

The number of tiers on a spiral system can vary widely, typically from 10 to 40 tiers per drum, dictating residence time and cooling capacity.

Temperature range

This equipment is designed for cooling applications, typically reducing product temperature from ambient or elevated levels down to chilled temperatures, often above 0°C.

Construction materials

Food-grade spiral coolers commonly feature stainless steel construction for hygiene and durability, particularly for product contact surfaces and the cabinet interior.

• What is the primary benefit of a twin spiral cooling system?

  A twin spiral system offers increased cooling capacity and potentially greater operational flexibility within a relatively compact footprint compared to a single large spiral or linear cooling lines.

• How is the cooling medium typically supplied to a spiral cooler?

• What maintenance is typically required for a spiral cooler?

• Can this type of cooler handle different product types?

• What factors influence the cooling time for products in a spiral cooler?

• Is a skid-mounted system advantageous?

Spiral freezers are valued in food processing for their compact footprint and efficient product handling. Buyers typically appreciate their gentle freezing action, which preserves product quality and texture. When purchasing used equipment, inspection of the spiral belt condition and refrigeration system performance is essential. The stainless steel construction generally resists corrosion well in demanding environments. Common considerations include maintenance costs and spare parts availability, though reliability across production runs remains a noted strength.
