Pasteurising with the highest efficiency
Better safe than sorry
Product safety is a core issue in marketing your beverage. Only safe processes and a reliable shelf life that
meet the demands of the trade and
of your supply chain guarantee the
continuous success of your products.
Pasteurisation is very often procedure
number one when it comes to preservation of the just filled products. Individual programmes for all products
and container types make sure the
product will be optimally preserved
and handled gently throughout the
process. The LinaFlex tunnel pasteuriser offers a pasteurisation process
with precise PU control and an efficient use of resources. You will get a
pasteuriser configured in single or
double-deck form that is specifically designed to meet your operational requirements. For example, it will
be equipped with conveyors which
are adapted to the properties of the
containers. The quick installation of
the modular pasteuriser is another
plus for high-performance production plants.

Method of operation
Tunnel modules
The tunnel modules are divided into
temperature zones which allow gentle heating and cooling of the containers before and after pasteurisation. The spraying system with
snap-in spraying nozzles jets the
containers with water that has been
tempered exactly for the treatment
zone involved. So the containers are
treated uniformly and systematically
with an economical use of water.

CHESS heating system
The patented CHESS heating system
allows for running the pasteuriser extremely economically. Only one
heat exchanger supplies the individual zones of the pasteuriser with hot
water. A buffer tank collects the overflow and returns it to the pasteurisation zones via the heat exchanger.
This closes the water cycle, thereby
slashing the heating-up times for
the individual zones and saving vast
amounts on energy and water consumption.

Conveyors
Conveyor and transport systems
Two conveyor variants which are
optimally adapted to the conditions
in the pasteuriser guarantee safe
and gentle transport for each type
of container.
■■ All conveyor belts are made of
durable materials and low on
maintenance and wear.
■■ Narrow transfer areas at the container infeed and discharge points
ensure a streamlined product flow.
■■ The high-performance plastic rollers at the bottom reduce friction
to such an extent that only one
main drive is required.
■■ The Marathon Belt and Ironman
Belt conveyors can be retrofitted to
existing pasteurisers.
krones LinaFlex
Marathon Belt
■■ Stable and robust structure thanks
to its stainless steel frame
■■ Plastic body with excellent transfer
properties
■■ High stability with respect to
chemicals
■■ Extremely long service life and low
wear due to minimum friction
■■ Best results for all container types
Ironman Belt
■■ Stainless steel conveyor
■■ Special enhancement of the tried
and tested Marathon Belt
■■ Guarantees smooth and safe
pasteuriser operation even with
increased probability of broken
glass
■■ Robust stainless steel dead plates
for a short and gentle container
infeed and discharge
■■ The open surfaces allow for a
proper water flow, thus preventing
clogging with dirt
PU control PUC3
PUC3 PU controller
Maximum product safety - under all
circumstances: The dynamic PUC3 PU
controller makes sure the required PU
values will be accurately maintained
even during production interruptions
or in the event of a machine stop.
■■ The PUC3 calculates the PU values
in real-time and, at the same time,
generates a preview of the expected results.
■■ The thermal properties of the
product, the spraying temperature,
as well as the conveyor speed are
considered for PU calculation.
■■ The system allows for product
change on-the-fly in the
pasteuriser.
■■ Retrofitting new products
is facilitated thanks to the
Windows-based system.

Your benefits
krones LinaFlex
■■ Uniform and precisely defined
■■ Hygienic general conditions
■■ Save your resources
■■ Short installation times thanks to
heat transfer
Thanks to the fine-tuned spraying
system, the product is safely pasteurised at every position in the
pasteuriser. The PU logger system
can be used for documenting this
continuously uniform condition.
Water and energy requirements
are decisive pasteurisation factors.
With LinaFlex you set this parameter to a low level. In addition, customer-specific cooling concepts
and heat recovery concepts in the
pasteuriser maximise the saving
effects – with maximum pasteurisation precision.
■■ Quick maintenance
You can access all pasteurisation areas quickly and without
any tools. The large maintenance
openings at the individual zones
and the accessibility of the spraying water system from above
allow to quickly complete all operation and maintenance tasks. The
double-deck pasteuriser also offers
good access with the lateral catwalks.
Clean Design manifests itself in
many details: Spraying pipes with
automatic reversible flow capability, sloping surfaces in the tanks
and an automatic central draining feature guarantee maximum
hygiene in the LinaFlex.
modular structure
Thanks to the modular design,
your plant will soon be ready for
operation after the new pasteuriser has been installed. And that,
of course, is a vital factor for your
production planning.
