Typical Specifications

Typical capacity

Throughput for this class of equipment typically ranges from 100 kg/hr to over 1000 kg/hr, depending on product and tunnel length.

Power supply

Units of this type commonly require a 3-phase electrical supply, typically 400V, 50Hz.

Cooling medium

Most cooling tunnels utilise refrigerated air circulation, often with a dedicated chiller unit.

Belt width

Common belt widths for food processing cooling tunnels range from 400mm to 1200mm.

Construction material

For food contact and hygiene, units are typically constructed from food-grade stainless steel.

Temperature range

Cooling tunnels are generally designed to achieve product temperatures ranging from ambient down to approximately 0-5°C, depending on the cooling system.
