said. " In addition, our multi-fuel technology CleanBake ovens
can be fitted with electric elements or hydrogen burners
to further lower or eliminate the carbon footprint without
any change to developed product baking profiles. "
Joakim Nordell, export sales manager, Stewart
Systems, a Middleby Bakery company, explained that
the precise location of the burners along the pan path
in a conveyorized oven generates energy efficiency and a
uniform baking profile. He said Stewart's Chevron burners
supply a gradual and even heat distribution around
the pan and product. Correct airflow in the oven also affects
baking consistency.
" We recommend longer runs of the same product
to maximize efficiency rather than short and multiple
changeovers, " Mr. Nordell said. " It's also important to
follow maintenance schedules and ensure the oven and
its combustion system are well-tuned. "
On new or existing ovens, Mr. Nordell pointed out
that utility monitoring systems may also alert operators
of unusually high gas consumption that may be caused
by running exhaust fans too high, burners needing
cleaning or untuned burners, which all result in excessive
heat and wasted gas.
Mr. Menardo said TP Food Group's ovens can integrate
burners capable of diluting a fraction of hydrogen or liquid
propane gas in the standard fuel used, leading to greater
efficiency and environmentally friendly operations. The
company also offers electric inline and spiral ovens that can
rely on renewable energy. In cyclothermic ovens, he added,
heat recovery systems reuse exhaust gases to bake products,
while spiral ovens can integrate air impingement technology
to maximize the use of preheated air.
Moreover, spiral and multideck ovens provide additional
options to lower energy consumption.
" Typically, these ovens feature a single burner heating
up a flow of thermal oil feeding a set of pipes placed
in a properly insulated baking chamber, " Mr. Menardo
explained. " With such oven designs, operators can efficiently
achieve high oven springs by using less than 8
kW per square meter of thermal energy. "
He said even more savings can be achieved in thermal
spiral ovens by minimizing the size of the infeed and
outfeed sections of the baking chamber together with
reducing oven belting exposed to the outside environment.
TP Food Group's ovens can also install automatic
product detection and monitoring systems that regulate
the oven steaming system used for creating many specialty
and artisan breads and rolls.
Gemini Baking Equipment has added various turbulence
features in all zones of its ovens to provide an even
bake color and avoid weak and lightly baked sidewalls
in panned products, noted Jerry Murphy, the company's
vice president of sales.

In a conveyorized oven, the burners' location along the pan path
generates energy efficiency and creates a uniform baking profile.
Sosland Publishing Co.
He said its most recent innovation, a Quad turbulence
zone, is comprised of four, 3 hp Siemens balanced recirculation
power packages mounted in each turbulence zone
on opposite sides of the oven for enhanced convective
baking. Gemini/WP tunnel ovens also offer gap control
where oven temperatures are lowered to manage heat
flash when products aren't in the oven.
