and installation of a spray dryer control system for a pharmaceutical
A PC-based control package and (HMI) workstation were used
to provide control of a spray drying process.
The PC-based control package is used to control product temperatures,
vessel temperatures, spray dryer pressure, start/stop control
of feed pumps, etc. All control loops and device interlocks
are programmed in the control package. The package interfaces
with separate I/O modules for control. The HMI provides system
status and the means to setup and control the process.
The entire system was validated for IQ, OQ and PQ qualifications.
