Mixing and Granulation - GEA Pharma Systems

Understanding& ControllingYour Process•ControlsIn order to ensure safe, efficient operation of the unit, the systemis controlled through an industrial computer Human-MachineInterface (HMI), with all functions deriving from a plc controller.This design allows the control interface to becompletely washed down during productchangeover. Furthermore the HMI may be upgradedto allow processing with flammable organicsolvents, in an ATEX Zone 1/21 area. Completing theATEX Zone 1/21 upgrade, flammable gases may beprevented from entering the controls enclosure inthe base of the Laboratory PMA-Compactmachines by purging with compressed air.The physical safety of the operator is assured withthe use of safety locks and proximity sensors toprevent access to the bowl and discharge when theequipment is operating.Binder addition and end point determination maybe controlled through the HMI, manual control orfully automated, recipe control for the unit.Data acquisition can be delivered through a 21 CFRPart 11 compliant, on-board data capture devicerecording critical parameters throughout the processand allowing information downloads through anEthernet connection.Aeromatic-Fielder can supply standardised andbespoke SCADA interfaces, utilising software, suchas iFIX from GE Fanuc Automation, to providedata collection, management and recipe drivenprocesses, fully compliant with FDA 21 CFR Part 11.8
