Unitherm XL Spiral Oven

• High-volume cooking of poultry, red meat, and fish products.
• Baking and roasting of various food items, including pastries and vegetables.
• Processing of ready meals and convenience foods requiring consistent heat treatment.
• Industrial-scale cooking where continuous throughput and uniform product quality are critical.

Typical capacity

For this class of equipment, throughput can range significantly, with larger units commonly achieving several tonnes per hour, depending on product type and cooking requirements.

Power supply

Industrial spiral ovens typically require a robust three-phase electrical supply, commonly 400V or 415V, 50Hz, often with significant amperage draw.

Heating medium

Units of this type commonly utilise steam, thermal oil, or direct gas firing for heat generation, offering flexibility in operational costs and heat transfer efficiency.

Belt width

Belt widths on XL models are typically substantial, often ranging from 800mm to 1200mm, accommodating a wide array of product sizes and volumes.

Footprint

Spiral ovens are designed for high capacity in a relatively compact footprint compared to linear ovens, but still require significant floor space and vertical clearance for installation and maintenance.

Temperature range

Operating temperatures commonly range from 80°C to over 250°C, providing versatility for various cooking processes such as roasting, baking, and steaming.

• What are the primary benefits of a spiral oven over a linear oven?

  Spiral ovens offer a significantly larger cooking surface within a smaller footprint, enabling higher throughput and more efficient use of factory space. They are ideal for continuous, high-volume production.

• What kind of maintenance is typically required for a spiral oven?

• Can these ovens handle different product types?

• What utilities are needed to operate a spiral oven?

• Is specialist installation required?

Ovens and sterilizing ovens hold strong reputations for reliability in laboratory and pharmaceutical settings. Buyers typically value robust construction and consistent temperature control. When purchasing used equipment, inspectors should verify heating element condition, temperature calibration accuracy, and chamber integrity. Common strengths include durability across extended operational lifespans and cost savings versus new models. Industry sentiment favours models from established manufacturers with documented maintenance histories. Thermal uniformity and energy efficiency remain key purchasing considerations.
