Optimisation of the granulation and drying process depends on efficient and
effective cleaning. Automation of the cleaning process ensures repeatability,
allows validation and minimises down-time. In recognition of the fundamental
role played in today’s advanced powder processing industry by automated
clean-in-place procedures GEA Pharma Systems and Aeromatic-Fielder™ has
developed a unique approach to CIP.
Shaft seals provided in a “cartridge” design for easy removal
and replacement
The shaft seal symbolises, the many developments
that the PMA has seen over its existence. The PMA-Advanced™ High Shear
Granulator utilises a cartridge-mounted seal system that exhibits
excellent performance for efficacy, clean-down and wear-life, without the need
to purge compressed air through the seal and into the process. Maintenance
benefits include rapid replacement and condition monitoring.
Clean line discharge valve
The circular discharge chute
design is based on “quick exit” and clean drop of granule with minimum “hang
up” surfaces. The discharge valve has evolved to ensure the minimum of surfaces
are exposed to the product, making it simple to clean, either manually or as
part of a CIP recipe.
Concealed Services (optional)
The Filter system can be
mounted in the hinge mechanism with exhausted air passing through the centre of
the hinge. This creates a less cluttered working space with fewer hoses being
run in the process area to the machine. Furthermore pneumatic pipework for
actuators and other similar services may also be run through the hinge.
CIP* and WIP
All the high shear granulation systems can
be supplied with a wide range of washing-in-place and fully automated
cleaning-in-place options. CIP features include a combined vacuum cover seal
which prevents product leaks, lifting impeller, automated spray head and filter
cleaning, and internal O-ring seals. *CIP patent
