What’s New
GEA Niro invests heavily in research and development and strives continually
to find new and more efficient ways of satisfying its customer's needs. Here
are just a few examples of how Niro has led its market in recent years
The Wrap around separator
The traditional way of separating product vapours in a MVR evaporator is to
use a separator standing adjacent to each calandria in the system. Now GEA Niro
has developed a new system that reduces the plant footprint by up to 40%
without any increase in power or loss of separation efficiency.
GEA Niro has achieved this by using the wrap-around separator.
This fits around the base of the calandria and so occupies very little
additional space. This can make a significant difference to the size of the
building necessary especially when more than one effect is used in the
system.
The In-Line filter The In-Line filter is a very
simple addition to the plant that prevents the clogging of the distribution
system of the plant with waste solid matter during the daily CIP cycle.
The cleaning solution is fed into the filter tangentially to allow any
large contaminants to collect in the bowl. Small fines are trapped in the
stainless steel gauze that runs up the centre of the filter.
Sludge is
discharged intermittently from the filter bowl. As the filter is supporting a
25m water column the sudden drop of pressure caused by the discharge causes the
filter gauze to be backflushed allowing the accumulated deposit to fall into
the sludge bowl and be discharged in the next cycle.
The In-line
filter makes the daily CIP process much faster and more effective. As the
filter is never opened there is no risk of bacteriologic recontamination as
with other filters.
The Solution to Thermophilic Spore Build upGEA Niro
has solved the taxing problem of thermophilic spore build up during the
pasteurisation of milk prior to evaporation. The solution can be supplied on
new plant or as a retro-fit for existing installations.
Spores are
produced typically after 10-14 hours running time when conditions for bacteria
growth become unfavourable. Although they are not harmful in themselves their
presence is often used by large customers to provide an indication of the
quality of the management of a plant, a significant influence in the purchasing
process. The spores are extremely heat resistant and can reactivate themselves
when growth conditions again become favourable.
Through research, GEA
Niro has discovered that the spores build up during the pre-heating stage and
has developed a simple and cost-effective technique that eliminates the
environment in which these spores can form. Exactly how this is done is
commercially sensitive information however, if you want to know more please
