TUIG Indirect Gas Heated
Tunnel Oven
Sveba-Dahlen Indirect Gas Heated Tunnel Oven
High performance and reliability
– in a fl exible way
Oven zone – a Tunnel Oven can be
delivered in two, three or more zones.
Sveba-Dahlen’s tunnel ovens are very energy
effi cient, fl exible and user friendly. Well known
for their high performance, reliability and low
maintenance.
Our indirect heated tunnel ovens offer a
unique fl exibility and can produce all kind of
products. Band width is 2,5 meter and the
length of the oven is calculated to meet the
capacity need of the customer.

Energy effi ciency
The oven is very energy effi cient; the burners adapt their heat output
to the demand from each zone.
Reliability
When a burner fails in a “standard” oven with just one burner, then
the entire oven shuts down. In the Sveba-Dahlen oven only the top
or bottom heat of one zone fails.
Zone 3
The tunnel oven is divided into a number of
heat zones where each zone has a separate
regulation of top and bottom heat. This
provides a possibility for an optimal setting of
the heat curve for each product baked.
Easy to service and maintain
All components and functions such as fans, burners, electrical
cabinet, motors and drives are easy to access, inspect and to
service.
Zone 2
Zone 1
Quick
installation
The oven is built up
with modules; each
module is optimized
for transportation.
This means that the
production time and
installation time is
reduced to a minimum.

Separate burners
for top and bottom heat
With separate burners for top and bottom heat in each zone the
oven becomes very fl exible and gets a very fast reaction time
when adjusted for new products.

Flexible adjustment
Each zone is working independently since the temperature is set with
individual temperature regulators in the same way as an electric oven.
There is no need to adjust the temperature with dampers as on a tra-
ditional oven because the oven is set up at installation and there after
everything is controlled with the control panel.
User-friendly controls
The control panel is designed to give best overview and
simple control displaying baking time, temperature etc. Recipe
handling of process parameters, handling of alarms and data
logging is available as an option. Connection to a master
control system is another possible choice.
Full colour touch-screen together with conventional temperature regulators gives the operator total overview and control
of the baking process.

Indirect heating
The Sveba-Dahlen Indirect Gas Heated Tunnel Oven heating
channels are installed above and below the oven belt along the
entire oven.
Air turbulence
For many types of products, it is appropriate to use a
combination of radiant heat and air circulation. If so the oven
can also be equipped with turbo zones.
With air circulation, the baking time can be shortened, and
lower temperatures utilized. This also gives the sides of the
bread better colour, especially when baking with tins. By
controlling the speed of the drive motor, optimal turbo power of
the turbo fans can be obtained.
Inspection door
The ovens have inspection doors made of glass, with built-in
lighting for easy supervision of the baking process.
Stainless steel
We manufacture the outside exterior of the oven in stainless steel.
The materials in the oven chamber are specifi cally selected for
each oven, for the baking temperature and the product range. All
the ovens are insulated with rockwool to minimize the heat loss.
Belts and drive
Two different belt types are available as standard. The speed of the
belt is controlled by a frequency converter to maintain the exact
baking time. Longer ovens and ovens for heavy products are fi tted
with double drive rollers and double driving motors. The belt drive
and tracking system is designed for optimal reliability.
Exhaust damper
The exhaust damper is adjusted manually. A PLC control can be
selected as an option and with this option the exhaust damper
can be motor driven.
Steam system
In ovens built for connection to a steam generator, a part of
the fi rst oven chamber is provided with steam spreading boxes
made of acid proof stainless steel. Regulating indicator valves
with dial clocks are fi xed on the sides of the oven to set the
correct volume. Steam control with quantity control/photocell
control can be selected as an option.
Anything else?
We can also offer a number of options for example humidity
control. Please contact us with your requirements and we will
offer you a solution that works.
