fill Nestea ice tea in 0.5, 1.0, 1.5 and 1.75-litre containers. From the Contiform blow-moulding room,
the bottles are passed to each of the three PET- Asept lines. Each line has its own filler room, into which the empty bottles are passed through a “hole in the wall”, and from which the full bottles then leave through a small opening as well. Each of the PET-Asept lines features a volumetric VODM-PET filler, which is coupled to an isolator, a rinser and an aseptic capper in a small cleanroom, and receives the closures from a closure steriliser. The filled containers then arrive in the third separate hall, where the bottle flow is then divided into two tracks, each of which
leads to a
Polozova. “Contipure offers us a whole series of advantages. Firstly, we can do without the air conveyor, which means reduced bottle losses and complete elimination of air conveyor maintenance, plus enhanced microbiological quality of the product without the risk of recontamination. Secondly, we save on space, reduce our energy consumption in terms of compressed air for the conveyors and of steam for the filling function, and we can handle container production and filling with one operator instead of two.” The line comprises a Contiform S 20 with a Contipure module, a Modulfill filler with a Checkmat in a monobloc configuration, plus a Contiroll HS wrap-around labeller, a Variopac Pro packer for multipacks, and in terms of process technology a Contiflow mixer and a Varioflash pasteuriser.
The filling factory’s basic concept In the initial phase, the company started off with a Krones PET-Asept line, a Krones EHF (Enhanced Hygienic Filling) line and a Kosme line for large-size containers. In the late summer of 2007, these were joined by a second PET-Asept line. For the first three Krones bottling lines, four blow-moulding machines from the Contiform range, plus the associated preform hopper loading and feed systems, are installed together in a single room. Of these, two Contiform S16s work for the first PET-Asept line. The EHF line is supplied by a Contiform S18, and a Contiform S20 serves the second PET-Asept line, subsequently installed in November 2007. In 2009, Krones additionally installed a third PET-Asept line, which is principally used to

Sleevematic labeller with a Shrinkmat shrink-tunnel. The flows of labelled bottles
are then ‘‘
The design of the EHF line is very similar,
with just the following differences: the rinser- filler monobloc is not aseptic, but it is separated from the surrounding air by a cleanroom. The sole labeller used here is a Contiroll for wrap-around dress. In addition, a handle applicator has been integrated, and the Pressant palletiser operates in the single, not the duplex version. In comparison to the first one, the second
The filled containers then arrive in the third separate hall, where the bottle flow is then
merged again, and blown off. They now pass through a Sleevematic labeller, after which a Checkmat inspects the bottles for label placement and fill level before another Accuflow again creates some buffering time in order to assure the smooth functioning of the downstream Variopac PFS, in which 12-bottle shrink-packs are created. Filling and packaging has now been completed. The packs are conveyed to the block-type warehouse, at
the beginning of which a
Pressant Uni Duplex palletises them and a pallet wrapper secures the stack.
divided into two tracks, each of which leads to a Sleevematic labeller with a Shrinkmat shrink- tunnel.
PET-Asept line installed offers even more options: the possible range of format variants is greater. In addition, it can bottle both still beverages aseptically, and carbonated products non-aseptically. For this line, as for the third PET-Asept line, Krones was also responsible for the process technology, with the CIP system and the blending kit.
The Kosme line, finally, produces and fills in a separate part of the building 5-litre PET containers with still water at a speed
of 2,000 containers an hour. It consists of a Kosme large-mould blow-moulding machine, a compactly dimensioned rinser-filler-closer monobloc in a separate room, a handle applicator and a Kosme labeller. Here, too, fill level and label placement are inspected by a Checkmat HF. The Kosme Monocombi and Nastropack erect the cartons, pack them with bottles, and then seal them. An X04 palletiser loads the pallets, which are then wrapped.
