a twin-flow process and single-flow

• a hot or cold twin-flow process both
for product processing and for bottling
on a dual filler.
Empirical feedback from actual
operations had confirmed that aseptic
inline blending offered very good
preservation of the pulp, excellent dosing
accuracy, and a high line output.
Special challenges
The project posed some rather special
challenges for Krones. During the retrofit
job, quite a few very deep-reaching
interventions were required in some
of the existing processes at Coca-Cola
HBC Eurasia and in the Krones lines
already in place. This could be assured
only by meticulous preparation and
ultra-thorough planning. Everyone
involved worked excellently together,
with several teams dovetailing for
smoothly maximised efficiency: Coca-
Cola HBC Eurasia and its operators,
the service personnel, and the experts
of pulp and juice. There must be no
more ice in the mixture, the temperature
should not be too low, and the mixture
has to be homogeneous. When the
slurry meets these criteria, the product is
released by the laboratory, heated up in
the pasteuriser, and cooled down again.
The pasteuriser’s output is approximately
two cubic metres an hour, which can be
individually set in each recipe. Through
cross-corrugated tubes, the slurry is
then gently and dependably heated up
in the shell-and-tube heat exchanger,
and delivered by screw-spindle pumps.
Minimised distances, few changes of
direction in the system, and elimination
of control valves in the product path
ensure that the product is handled with
maximised gentleness. After the slurry
has been heated up in the system, and
then cooled down again, it is passed to
the sterile tank, with a usable capacity of
10 cubic metres, installed near the filler.

from Krones Process Technology. A
tight delivery deadline and a minimised
commissioning timeframe upped the
pressure still further.
The kit was manufactured, tested at
Krones and delivered to site without a day
being wasted. And the commissioning
time for the entire system could hardly
have been shorter, at just three weeks. All
the deadlines stipulated beforehand by
Coca-Cola HBC Eurasia had to be met,
so that the product could be placed on
the Russian market in good time. The
paramount priority during the entire
process, moreover, was to ensure gentle
handling of the product and minimised
product losses.
How the pulpy products are
made
The pulp is delivered frozen in 180kg
drums. To enable it to be processed,
it first has to be thawed for around
24 hours. This is done inside the hall
at ambient temperature. The slurry is
required to exhibit defined proportions
