Electric Heated Tunnel Oven

Sveba Dahlen delivers electric tunnel ovens to customers all around the world. Each oven is based on a basic concept and then adapted to the customer’s wishes and requirements.

The ovens can be equipped with many types of belts, such as different kinds of wire mesh belts and solid steel belts. Electric heated ovens are produced in belt widths up to 4,2 m.

They are produced in two different basic models, depending on the baking temperature to be used. “Normal temperature ovens” of up to 350°C and “high temperature ovens” of up to 500°C are available.

    Air Flow Turbo Zone

    Effective baking with the Air Flow Turbo Zone. Air flow above the belt and / or with repeated vertically Turbo air flow through the belt. The zones can have individual settings for different recipes.
    HMI Control Panel with touch screen

    Tunnel Oven Control Panel

    The HMI control panel with touch screen is easy to overview and operate. Control the top and bottom heat in all zones, recipes, alarms and more. Get informative logs and do your software updates over the internet - quick and simple.

    Heating Elements

    Our own high quality, specially designed, heating elements which always is adapted to the customers production in sense of effect and quantity. By always adapt the elements to each case, the baking results always reaches highest quality.

    Energy efficient ovens

    In the electrically heated oven the heating elements are installed directly in the oven chamber and the oven is separate regulated in each zone for top and bottom heat. This means that power is only used in the different zones when and where.

    Two temperatures

    “Normal temperature oven” up to 350°C. “High temperature oven” temperature up to 500°C (932F).

    Multiple belt types and widths

    Available belt types: Wire mesh belt and Solid steel belt. Available belt widths: 0,5 m to 4,2m (1,64 ft to 13,78 ft).

    Options & Accessories

    • Continuous recipe change

      • Changing recipe continuously in a zone immediately when the zone is empty.
      • Changing recipe baking time immediately when oven is empty.
      • Available with automatic function and manual handling.
    • Steam Regulation

      • Steam regulation on /off by photocell, off delay when no indicated bread.
      • Steam regulation on /off like above plus adjusting kg steam / hour.
    • kWH-meter and heating status check

      kWH-meter including heating element status check. In each zone box there are current transformers on the main cable after the main switch.

    • Humidity measurement

      By using humidity sensors in the different zones the humidity parameter can be measured and controlled.

    • Rotating belt brush

      Pneumatically, liftable and rotating brush for regularly cleaning.

    • Thyristor controlled heat

      For a more accurate regulation, the heating elements can be controlled by thyristor regulation.

    • Motorized dampers and oven doors

      Recipe controlled damper and oven door positions.

    • Water spray at the outfeed

      Gives a shinier product and improves the crust.

    • Walkway on top of the oven
