OVENS
XE Oven includes a humidity-controlled
product zone. Additionally, maintenance
is simplified, as electric oven components
are easily replaced, eliminating costly
downtime replacing, cleaning and tuning
gas burners.
Mr. Johnson noted Werner & Pfleiderer,
which Gemini represents in North America,
will display the new Thermador-E electric indirect
gas-fired tunnel oven at iba. The oven's
modular electric heating element assembly
is designed to be a replacement for the gas
burner and combustion chamber in the current
W&P Thermador gas-fired ovens. Electric
heat can also be retrofitted in these ovens.
A hybrid or all-electric oven can reduce carbon dioxide
and nitrogen oxide emissions because only low or no
fumes are created.
Mecatherm
Fuel Free (RF3) Convection Oven combines convection
heating with radio frequency to reduce bake time by up
to 50% in products with high fat and high hydration.
Mr. McCally said this hybrid oven technology has
the potential to quickly compete at a similar operating
cost per unit of production output of traditional gasfired
ovens.
WILL THE EO, OR ELECTRIC OVEN,
BECOME THE EV, OR ELECTRIC
VEHICLE, OF BAKING? THAT
DEPENDS ON A HOST OF FACTORS.
At iba, Auto-Bake will demonstrate its all-electric
F3 Convection Oven. Other Middleby Bakery companies
like Sveba Dahlen will feature its high-temperature
electric Artista Deli tunnel oven, while Baker
Thermal Solutions will showcase its Rapid Bake tunnel
oven that combines impingement and radio frequency
heating.
Meanwhile, RBS will roll out its new Emithermic
XE Oven design at iba. Instead of ribbon burners, the
Emithermic XE Oven bakes using electric radiant heat
elements, high-radiant Thermatec panels and convective
heat.
" The Thermatec panels and electric heaters deliver
a more balanced heat to the product and impart the
high-radiant energy required to develop the flavor
and texture of the crackers, " Mr. Martin explained.
" For greater flexibility and control, the Emithermic

Racking up savings
The TP Food Group offers single and dual deck tunnel
ovens that are fully electric and come with baking
surfaces of up to 270 square meters (2,900 square feet).
Mr. Menardo pointed out the ovens come with steaming
sections, steam regulation systems, reliable belt transmission
systems, efficient insulation, air turbulence
systems, air/steam recouperation systems and separate
baking zones.
For artisan and mid-sized commercial bakeries, sustainable
electric rack ovens have been around for a long
time. Koenig Bakery Systems offers an electric version
of the Roto Passat SE rack oven.
In addition to reducing CO2
emissions, the electric
rack oven reaches its desired temperature quickly,
even when changing programs for different products,
said Christian Benedikt, group leader, oven design
for Koenig.
" Installation is very simple as compared to oil or gas
heating. You do not need a flue gas chimney for flue
gas, " he pointed out. " It's an almost maintenance-free
operation because the oven does not contain a burner.
This means faster commissioning and no need for annual
statutory inspections. "
At iba, Koenig will feature its Roto Passat SE with a
" Save Energy " option that offers greater energy efficiency
in a smaller footprint. Moreover, several rack ovens
can be connected with Koenig's newly developed Smart
Connect system.
" This means that ovens can be controlled digitally,
monitored and analyzed in the office by the operation
manager, " Mr. Benedikt said.
While many regulatory questions and operational
challenges remain when it comes to sustainability, the
opportunities are almost electrifying with the current
and emerging advances in emission-controlling and
energy-saving technology for ovens.
