Fossil Free Electrical 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 & 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 350ºC and “high temperature ovens” of up to 500ºC are available.

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.

Options

  • 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.
     
  • 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. 
     
  • Motorized dampers and oven doors.
    Recipe controlled damper and oven door positions.
     
  • Thyristor controlled heat. 
    For a more accurate regulation, the heating elements can be controlled by thyristor regulation.
     
  • Water spray at the outfeed. 
    Gives a shinier product and improves the crust.
     
  • Walkway on top of the oven.
    Simplifies cleaning and service. 
     
  • Frequency inverters for the oven chamber exhaust fan(s). 
    Adjust the fan speed from the PLC screen. The system can be expanded for continuous under pressure / flow regulation.
     
  • Air Flow Turbo Zone.
    Frequency controlled speed. Individual setting for different recipes. Top heat turbo with air flow above the belt and/or with vertically Turbo air flow through the belt. 
     
  • Frequency controlled fan speed.
    Individual setting for different recipes. 
     
  • High power section in zone 1. 
    Add extra power heat elements in the first part of the bottom heat chamber. Controlled from PLC screen, and specified in the recipes.
     
  • kWH-meter including heating element status check.
    In each zone box there are current transformers on the main cable after the main switch.
