Carbon Infrared EmittersDisinfect Quickly and Reliably
All baking trays, conveyors and baking equipment in a
bakery must be hygienically perect at all times.
The elimination o mildew and ungal growth is always
the frst priority. Carbon inrared emitters CIR rom
Heraeus Noblelight disinect simply, quickly and saely.
That saves time, energy and costs.
Inrared radiation transers large amounts o energy
in a very short time. Inrared disinection is thermal
disinection, using controlled heat. The emitters direct
their heat precisely where it is required and or only as
long as needed. That prevents equipment as well as thebaked goods rom heat damage.
A study* at the Bremerhaven Institute or Food Technology
and Bioprocess Technology in October 2005 showed that
carbon inrared emitters kill germs reliably and practically.
In addition, thick spore layers, porous suraces and
dust particles pose no problem to the eectiveness o
carbon inrared. The deep-acting carbon inrared
radiation even penetrates porous materials and multi-layer
germ deposits.Carbon infrared emitters
disinfect baking trays and equipment.

Cost-effective disinfection
Disinection with carbon inrared emitters is reliable and
practical. The efcient emitters help to save time and
operating costs in bakery plants.
Extended maintenance intervals
Inrared heat also dries the carrying cloths used inbakeries. As a result, the useul lie o these carrying
cloths is signifcantly extended, considerably reducing
replacement costs. This saves maintenance costs and
time, especially when a bakery plant is operated around
the clock.
Requirements met
The studies showed that baking trays are disinected by
carbon inrared emitters at just 130140 C in less than
30 seconds. Depending on the emitter power, the
humidity and the desired speed, the germ reduction is
achieved within 10 to 30 seconds between 120 and
160C. By the use o carbon inrared emitters the
requirements o the EU hygiene regulations can be met.
The Technology
Carbon inrared emitters CIR combine the highly
eective heat radiation in the medium wave range
with the ability to provide sufciently high power densities.
Response times o the order o seconds provide or
extremely good controllability. Consequently, heat
is applied or only as long as required. Drying and
disinection cycles can be programmed and, in the event
o a conveyor belt stoppage, overheating o the baked
items or the baking plant itsel is prevented. The compactconstruction o an inrared system also allows retroftting
o inrared disinection into existing machinery.
Practically-based Tests
Experience has shown that it is benefcial to test the
material and application in conditions as near to those
ound in practice as possible. So the optimum emitter
or the heating process can be determined.
Heraeus Nobelight has established Applications Centres
to gather new knowledge though investigation and to
share experiences with customers. Only when you know
and understand the dierent applications can you use
inrared productively.
Technically qualifed personnel carry out the tests.Customers can bring along their own materials and
have access to an extensive results database, with over
500 documented tests with ood to provide design reerence
points. IR test modules are also available to allow on-site
tests to be carried out at customers own premises.

Baked rolls can be disinected immediately beore packing
by a short heating o the surace.
This extends shel lie and keeps the rolls resh or longer.
