GRUNWALD GMBH
GRUNWALD GMBH – a family-owned German mechanical
engineering company, located in Wangen im Allgäu
with more than 190 employees and reliable partner
for dosing, filling and packing.
GRUNWALD GMBH is leading supplier of format flexible
cup and bucket filling machines for filling various products
in prefabricated packaging materials (cups, buckets,
trays, similar containers, jars).
GRUNWALD filling techniques allow for a quick and flexible
response to the manifold requirements of the markets at
any time. Since 2019 all GRUNWALD machines are peroxidefree.
requirements for observing maximum hygiene levels in the
production of dairies and the food industry. Up-to-date
machine technology guarantees a reliably higher product
safety and combines maximum possible flexibility with
maximum performance and reduction of running costs on
the basis of maximum hygiene standards at the same time.
The biggest advantage of this guaranteed reliable, certified
and peroxide-free sterilisation system is not using any
chemicals which means it is free of peroxide. Therefore it
respects all the health of the machine operators to a large
extent and does not have any impacts on the environment.
In addition the issue with the overdosing of chemicals has
been solved!
The pulsed light high-performance UV(C) sterilisation
was tested by several independent German institutes and
they also confirmed its effectiveness. They certified that
this UV(C) sterilisation was an ultra-modern and efficient
alternative sterilisation procedure which presents no health
hazards and which gives reliable service without using
peroxide and guarantees maximum sterilisation rates.
Ultraclean sterilisation for cups and buckets
The pulsed light high-performance UV(C) sterilisation rate for
cup filling machines was well tried and tested over the past
few years. In the meantime it has been further developed
and now it can also be used on rotary-type and inline bucket
fillers for handling buckets up to 20 litres. A sterilisation
rate of at least LOG4 is guaranteed for buckets from 1 to 10
litres. In addition this procedure can be generally applied for
all standard cups and lids used by the food industry.
The central point of the hygiene concept developed by
GRUNWALD is the guaranteed reliable sterilisation system of
pulsed light high-performance UV(C) sterilisation. It varifiably
guarantees a sterilisation rate of at least LOG4 for cups,
buckets and lids. With this procedure the packing materials
are sterilised with pulsed UV(C) radiators and not with H2O2.
The next GRUNWALD-ultraclean (UC)
machine generation
Meanwhile the development engineers have implemented
the next stage of the GRUNWALD ultraclean (UC) concept:
GRUNWALD-FOODLINER 20.000 UC. The 10-lane inline cup filler –
an intelligent filling and packing machine
• in ultraclean (UC) design with peroxide-free hygiene concept
• maximum hygiene standard and at the same time maximum
speed (sterilisation rate ≥ LOG 4 at 40 cycles/min.)
• fully-automatic tunnel cleaning
• highest possible flexibility
• up-to-date, fully integrated industry 4.0 solution guarantees
maximum process reliability in order to entirely avoid production
downtimes.
