The Haas biscuit oven program allows the production of all kinds of hard and short dough biscuits, crackers and cocktail biscuits, swiss rolls or layer cakes. The most suitable oven type for a certain product and for certain production conditions can be selected from different baking systems. Moreover, it is also possible to combine two different oven systems to a hybrid oven. All ovens are available in working widths from 800 to 1600 mm. 
MULTIVARIANT OVEN - Technical Data
  • indirectly heated radiant oven
  • natural or liquid gas
  • 2.0 m long modules with efficient rock wool insulation, welded baking chambers of carbon steel bolted to each other
  • automatic ignition, burner monitoring and temperature control
  • optional addition of convection: the advantages of indirect radiant heating (good product development, universally applicable, high moisture possible) are combined with those of convection (shorter baing times, good drying, low baking temperatures, uniform product coloring)

CYCLOTHERM OVEN - Technical Data
  • indirect heating by natural or liquid gas or by heating oil
  • 2.0 m long modules with efficient rock wool insulation, welded baking chambers of carbon steel bolted to each other
  • automatic ignition, burner monitoring and temperature control
  • centrally arranged high-capacity burner in each control zone
  • heating of gases by a closed circulation system in the burner chamber; gases are passed through ducts into radiators above and below the baking band

GAS MULTI-BURNER OvEN - Technical Data
  • directly heated radiant oven
  • suitable for natural or liquid gas
  • 2.0 m long modules with efficient rock wool insulation, welded baking chambers of carbon steel bolted to each other
  • automatic ignition, burner monitoring and temperature control
  • 3-zone-burners (adjustable across the width) are specifically employed for uniform distribution of moisture and uniform product coloring across the width

ELECTRIC MULTI-BURNER OVEN - Technical Data
  • electrically heated by tubular radiators consisting of a stainless steel tube enclosing a ceramic body with embedded resistance heating wires made of highly heat-resistant material
  • 2.0 m long modules with efficient rock wool insulation, welded baking chambers of carbon steel bolted to each other
  • automatic ignition, burner monitoring and temperature control
  • infinitely variable thyristor control guarantees exact agreement of actual values with the set values
  • steam extraction and discharge adjustable by manually operated dampers (placed every 5 m)
