INDUSTRIAL OVENS AND HANDLING SYSTEMS FOR THE GLOBAL BAKING INDUSTRY
Industrial ovens and handling systems for the global baking industry
A specialized process like baking is not easy to automate. So, building
a complete oven for a variety of products calls for more than just knowledge
of construction and process control. It demands intelligence, skill, an understanding
of the baking process, and a world of experience.
These are the strengths of Den Boer Baking & Handling Systems, and they have been
brought together in a new line of ovens: The Den Boer Multibake® Line.
The result of 100 years of oven-building experience
combined with worldwide product knowledge

ModularThe most important aspect of the new oven range,
with its four variants, is the modular design. This
enables an oven to be delivered relatively quickly-,
and exactly tuned to meet the demands of a specific
baking process. Because the modules are
entirely pre-assembled, considerable time can be
saved during installation. This means your new
oven is ready for use in next to no time.
Perfect BalanceThe new Den Boer Multibake® Line offers an
optimum price/quality ratio, and perfect control
of the baking process. As always, quality is a first
priority at Den Boer. The Den Boer Multibake®
Line: the perfect balance.
This oven could be constructed with
doors on the opposite burnersite.
Top and bottom heat individually
adjustable. 4-8 modulating burners
per module.
Vapour hood with labyrinth filters on
the outfeed side of the oven.
Den Boer Multibake® DThe Multibake® D oven is a directly heated oven. The required heat is created directly in the
baking tunnel by means of modulating multi-ribbon gas burners. Each top burner is equipped
with an electronic air valve to prevent cold air flow inside the oven baking chamber when the
burner is switched off.
ConstructionThe baking tunnel is divided into modules and guarantees
an even heat transfer to the product. The oven is constructed
completely with Corten steel and has a vapour-tight baking
tunnel which is divided into modular sections. The sections
are connected on a frame with a vapour-tight connection
between the sections.
Advantages• Top and bottum burners are individually controlled
(modulating).
• Moisture from the burners provides a positive influence on
the product development, taste, crust and structure.
Modulating burnersThe modulating burners design-consists of a specially rolled
and profiled pipe, fitted over its entire length with a stainless
steel corrugated strip burner bed. These control units
ensure ignition of the burner, gas valve control and flame
monitoring.
Insulation MaterialThe oven walls are heavily insulated with high-quality
materials. The high insulation value prevents costly heat
from escaping to the outside. With an ambient temperature
of 20¼C (68 ˚F), the exterior of the oven will never be hotter
than 43¼C (110 ˚F).
Each modulating burner is equipped
with a burner control unit, electrically
operated gas supply valve and ignition
pin which also serves as an ionization
pin.
Direct fired ovens can be constructed
with top and/or bottom convection.
Options: steam, gap detection and
energy management
Highly efficient heat flux by optional
use of infrared bottom burners in the
first baking zone.
Modules can be constructed
with doors to provide easy access to
the interior of the oven allowing easy
cleaning and safe access.
The plenums transport indirectly
heated hot air at high-speed
(impingement) to the top and
bottom of the products.
Vapour hood with labyrinth filters on
the outfeed side of the oven.
Den Boer Multibake® IThe Den Boer Multibake® I (Impingement) is an indirectly heated oven,
employing hot air transported at high speed to both the upper and lower
side of the product. This is accomplished using an industrial burner
coupled to a stainless steel heat exchanger.
Everything Independently AdjustableThe Den Boer Multibake® I is highly suitable for baking a
variety of products. This is possible because parameters
such as temperature, air speed and humidity can be set
independently from one another per baking zone.
The flexibility is increased further by the modular design
which allows installation to be completed quickly.
Advantages• Recirculation of air provides less energy and more control
of moisture.
• Significant reduction of baking time.
Moisture ControlThe drying speed of a product can be influenced by
adjusting the temperature, air speed and moisture content in
the oven. The moisture content of the air in the oven can be
increased by means of steam injection. The condensation
of the steam onto the product improves the heat transfer
to the center of the product and prevents drying out of the
outer layer. The oven can be fitted with automatic moisture
control in all zones, but is normally used in the first zone of
the oven.
Insulation MaterialThe oven walls are heavily insulated with high-quality
materials. The high insulation value prevents costly heat
from escaping to the outside. With an ambient temperature
of 20¼C (68 oF), the exterior of the oven will never be hotter
than 43¼C (110 oF).
The plenums are constructed with
specially designed nozzles. These
nozzles blow air at high speed into the
various baking zones. The height of
the plenums at the top can be
adjusted if needed, giving optimum
adaptability to each product.
Adding moisture during baking. The burner and heat exchanger are
combined in a compact unit. The air
to be heated for baking (process air)
is transported equally over the
heat exchanger by means of one fan.
The fan is equipped with a Corten
steel blower (frequency controlled).
Modules can be constructed
with doors to provide easy access
to the interior of the oven allowing
easy cleaning and safe access.
Radiator tubes in each module are
located underneath and above the
product conveyor.
Vapour hood with labyrinth filters on
the outfeed side of the oven.
Den Boer Multibake® RThe Multibake® R oven is designed with the cyclotherm principle or “heat wheel” system.
Heating is entirely indirect, using central burners outside the baking area.
The heat is transferred to the product by means of radiator tubes.
ConstructionThe baking tunnel is divided into modules and guarantees
an even heat transfer to the product. The oven is constructed
completely with Corten steel with a vapour-tight baking
tunnel which is divided into modular sections. The sections
are connected on a frame, with a vapour-tight connection
between the sections.
Advantages• Perfect oven for mono productions.
• No turbulence on top of the product.
Example of Radiator TubesThe baking tunnel is divided into modules of 2,2 mtr.
Radiator tubes for each baking zone are located underneath
and above the product conveyor. The radiator tubes are
connected to special distribution units for the supply and
exhaust of the recirculation of combustion gases.
Insulation MaterialThe oven walls are heavily insulated with high-quality
materials. The high insulation value prevents costly heat
from escaping to the outside. With an ambient temperature
of 20¼C (68 ˚F), the exterior of the oven will never be hotter
than 43¼C (110 ˚F).
Each distribution unit has its own
multi port regulator slide that operates
across the full width of the oven. Any
desired baking curve is possible in the
oven.
Higher and more heat transfer can be
created by applying ribbed bottom
tubes in the first baking zone.
Example of the cross-section of the
interior construction of the radiant
heating principle. Radiant heated
ovens can be constructed with top and
bottom convection.
Modules can be constructed
with doors to provide easy access
to the interior of the oven allowing
easy cleaning and safe access.
Free space underneath oven
construction.
Vapour hood with labyrinth filters on
the outfeed side of the oven.
The hybrid variant of the Den Boer Multibake® Line is a designcomprising multiple oven types
grouped in a single oven unit. In principle, any combination of the Multibake‘D’, ‘I’, ‘R’ and
even ‘HT’ modules can be assembled, allowing you to enjoy the unique benefits of each to
provide modularity and a perfect balance.
ConstructionThe baking tunnel is divided into modules and guarantees
an even heat transfer to the product. The oven is constructed
completely with Corten steel and has a vapour-tight baking
tunnel which is divided into modular sections. The sections
are connected on a frame with a vapour-tight connection
between the sections.
Advantages• A supreme control of baking practices.
• The combination of oven types ensures higher baking
quality and increased product uniformity.
Example of CombinationsThe baking tunnel is divided into modules of 2,2 mtr. for
each baking zone. As an example, an oven with a length of
total 18 modules can have 13 modules direct heated and 5
modules indirect heated.
Insulation MaterialThe oven walls are heavily insulated with high-quality
materials. The high insulation value prevents costly heat
from escaping to the outside.With an ambient temperature
of 20¼C (68 ˚F), the exterior of the oven will never be hotter
than 43¼C (110 ˚F).
Individually controlled exhaust valves
for an optimal baking result in the
several different zones and baking
practices.
Example of a transition from baking
practices.
The main control box only has one
central control system to monitor
manage, and maintain.
Den Boer Multibake® H
Flawless take-over at stone
floor execution.
Example of built in IR burners. Extended vapour hoods with grease-
extraction filter. To reduce baking
steam into the bakery to a minimum,
extended vapour hoods are fitted to
the oven infeed and oven outfeed.
Den Boer Multibake® HTThe Multibake® HT oven is a directly heated oven, the required heat is created directly in the baking
tunnel by means of infrared (IR) burners. There are different numbers of IR burners in each module.
In each module there are IR gas burners at the bottom side for the belt pre-heating.
Our high temperature ovens can be constructed as direct IR or indirect impingement.
ConstructionThe baking tunnel is divided into modules and guarantees
an even heat transfer to the product. The oven is constructed
completely with Corten steel and has a vapour-tight baking
tunnel which is divided into modular sections. The sections
are connected on a frame, with a vapour-tight connection
between the sections.
Advantages• Very short baking times.
• Less space required for the oven.
• Efficient and high output.
Pre-heatingThe burner intensity of the belt pre-heating will be
controlled by PLC as a separate baking zone.
The construction of the baking tunnel and the position of
the burners, guarantee an even and efficient heat transfer
to the product.
Insulation materialThe oven walls are heavily insulated with high-quality
materials. The high insulation value prevents costly heat
from escaping to the outside. With an ambient temperature
of 20¼C (68 ˚F), the exterior of the oven will never be hotter
than 43¼C (110 ˚F).
We engineer our take-over conveyors
with high temperature execution.
The product to be baked can be
transported by stone-belt, steel
plates or wire mesh.
Example of hatches with quick acting
closure.
