CLEANING IN PLACE
During the nineties the CIP'able bag filter concept was developed and it is
now becoming more and more the norm that these filters are fitted in the
exhaust systems from spray dryers, either together with cyclones in series, or
as the only means of powder separation and environmental control.
Niro
A/S has now developed the next generation of CIP'able / sanitary bag filters,
SANICIP™. These filters will give a large number of advantages in the operation
of the bag filter itself and the spray dryer in general. The spray dryer will
operate more economically with savings in energy consumption, lower noise
level, better control of finer particles and higher yield of raw materials,
meaning less effluent.
Secondary advantages include reduced space
requirements for a plant of the same capacity and less maintenance.
This new bag filter is unique and includes new features such as
internal CIP of the bags (patent pending) making it possible to reduce water
and chemical consumption and a newly developed purge air system (patent
pending) allowing CIP of the clean air plenum of the filter and also reduction
in the time it takes to dry out the filter bags.
