SANICIP II
Better efficiency, cost savings and easier maintenance
GEA has made a series of important
changes to its trusted
SANICIP bag filtration system
for food- & dairy spray dryers
in a long-term development
project that will provide valuable operational
benefits to users of the new equipment. The
new SANICIP II (patent pending) maintains
and controls the pressure drop through the
filtration bags more effectively by promoting
longer production times and reducing CIP
intervals. Combined with other advances,
such as easier maintenance and better space
utilization than its predecessor, bag life is
now up to 50 percent longer. These developments
add up to more reliable operation,
financial savings and a better working environment
for operators.
Following extensive studies with customers,
GEA identified key areas where design
modifications could be made in this new
generation of SANICIP technology. Using the
latest computational fluid dynamics (CFD)
techniques to optimize airflow within the
filter, GEA was able to reduce the length of
the filter bags from up to 7 meters to just 4.5
meters and, by reducing the diameter, and increasing
the number of bags within the filter
chamber, retained the total filtration surface
area of the system.
This fundamental change results in increased
practicality and efficiency while contributing
several additional benefits:
Shorter filtration bags and cages
Each filtration bag is supported by an internal
cage structure. The 4.5-meter cages are much
lighter in weight than their longer predecessors
making maintenance easier. Likewise,
the shorter cages can be fabricated as a sin-
