The up-to-date sterilisation system
for maximum hygiene
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.
Since at least the beginning of the meanwhile successful
actions for damages in the Monsanto proceedings in the USA,
many people have become aware that the production processes
of the food industry also bears many risks. It is an open secret
that the machine operators are exposed to a significant health
risk as long as peroxide is used for the disinfection of packaging
material. This is especially true for workers at the older cup and
bucket filling machines. The involuntarily bleached hair and eyebrows
of the workers operating these machines often show the
impacts of peroxide.
But what is going to happen if the first doctor attests the
health risks of peroxide? If the work council will demand to in-
