Graham Z3271 Steam tunnel

• Used for pasteurisation of packaged food products such as ready meals, sauces, or preserves.
• Suitable for sterilisation of containers or components in pharmaceutical or cosmetic industries.
• Commonly employed for heat-setting or shrinking of product labels or tamper-evident seals.
• Utilised in breweries and distilleries for post-packaging pasteurisation of bottled or canned beverages.

Typical throughput

Throughput for this class of steam tunnel is highly variable, depending on product size, dwell time, and steam temperature. Buyers should consult the seller for specific unit performance.

Power supply

Units of this type commonly require a 3-phase electrical supply, typically 400V, 50Hz, for the steam generator and conveyor drive.

Construction material

Equipment for food and pharmaceutical applications, such as this Graham unit, typically features a stainless steel frame and mesh belt for hygiene and durability.

Footprint

For a steam tunnel with a 3000mm belt length, the overall footprint will be longer than the belt itself, accommodating steam generation and control systems. Buyers should confirm exact dimensions with the seller.

Temperature control

Steam tunnels commonly offer adjustable temperature and dwell time to suit various product requirements and processing specifications.

Steam source

This unit includes a Hydromatik steam generator, which is typical for self-contained systems, eliminating the need for an external steam supply.
