Direct-fired ovens

Innovation in Food Engineering

Intense, controlled baking, ideal for thin dough products

Features of direct-fired ovens

The Termopan by Insertec DF oven is designed for processes requiring immediate, direct and powerful heat transfer. Using an open-flame burner system without heat exchangers, it reaches high temperatures from the very first section of the tunnel, making it ideal for products that require thermal shock, a crispy base and precise control over the final colour.

Heat is transferred directly from the burners to the product, primarily through radiation and natural convection, ensuring intense baking from the very beginning of the process.

The Termopan by Insertec DF is equipped with upper and lower burners distributed across different zones, each independently controlled to regulate temperature, colour and humidity.

Advantages of the Termopan by Insertec DF

  • Controlled thermal shock from the start of the baking process
  • Uniform colour and a crispy base, thanks to independent zone control
  • Stable temperatures of up to 350°C, with precise adjustments in each section
  • No heat exchangers involved (reduced maintenance)
  • High energy efficiency, with optional heat recovery

Engineering validated through thermal simulation

At Termopan by Insertec, we analyse the behaviour of heat and the product in each baking section.
This enables us to:

  • Adjust flame intensity and distribution to suit the product.
  • Assess the thermal impact on the internal structure and surface.
  • Define baking profiles tailored to speed, format and the desired moisture level.

The flame is not improvised. It is calculated.

Products suited to this baking method

  • Flatbreads: pita, naan, focaccia, tortillas and lavash
  • Industrial pizzas, par-baked pizzas and ready-to-eat pizzas
  • Crackers and certain baked snacks
  • Soft breads (in certain production lines in Latin America and the USA)
  • Certain types of biscuits (to develop a firm base)
