GRUNWALD GmbH
Successful model „ultraclean (UC)
hygiene design” for the dairy industry
The up-to-date sterilisation system for maximum
hygiene level without the use of peroxide
Reliably high product safety and observance of the hygienic rules
regulated by law are one of the most important issues of Grunwald
in terms of the development of new machines. We successfully
implemented this in the past few years with various new machine
concepts by using the latest technology and innovative ideas. The
further development of the rotary-type and inline bucket fillers
has especially focused on the compliance with the maximum hygiene
levels, the health of the operators as well as the reduction
of the operational costs. In addition, it had to be considered that
trade and consumers increasingly demand extremely long shelf
lives for the products from the dairy and food industry – even
for highly sensitive products. These long shelf lives can only be
achieved if the products are filled at a guaranteed maximum hygiene
level and if techniques are used which reliably sterilise the
surfaces of food packages (cups, buckets, lids and film).
So far, the sterilisation with conventional, chemical methods such
as hydrogen peroxide was very reliable and widely used. Even if the
general trend has been towards a heavy reduction of cleaning and
sterilisation agents for several years this still means that chemicals
are used for the sterilisation of packing materials. The market
requirements for natural products, the avoidance of chemical additives
and the necessity to protect the environment inevitably
leads to putting into question this sterilisation system.
For dairy products:

GRUNWALD-FOODLINER 20.000UC in 10-lane design
with pulsed light high-performance UV(C) sterilisation
system and with integrated tray packer
UV(C) sterilisation is the alternative!
With the hygienic solution developed, Grunwald set new standards
in terms of hygiene several years ago and has already
offered an alternative for the sterilisation of all packaging materials
which is completely safe to use and does not represent any health
threat. The pulsed light high-performance UV(C) sterilisation used
verifiably guarantees a sterilisation rate of at least LOG 4 for cups,
buckets, lids and seal lids.
The sterilisation system works without the use of peroxide –
guaranteed and reliable. It has been demonstrably tested by
several, independent German institutes. They confirmed that
“it works completely without chemicals and it does not have any
impact on the environment and staff”. Thus also the problem with
the overdosage of chemicals has been solved when using pulsed
light high-performance UV(C) sterilisation! Another advantage is
