Turn-key design and installation of a batching process for
a pharmaceutical manufacturer.

SUMMARY:

A programmable logic controller (PLC) was used to control the batch manufacturing process in a hazardous (Class 1, Division 2) location. A human machine interface (HMI) workstation and an operator interface terminal (OIT) were used to provide system status and allow operators to control the batch. 

DESCRIPTION:

The manufacturing process requires the sequential batching of a number of ingredients through various tanks, mixers and reactors. The PLC controls the sequencing of the batch as well as the various temperature, pressure and vacuum control loops used throughout process. The PLC interfaces with the HMI to prompt the operator at key points in the process. The HMI provides the operator with the means of entering batch sizes and recipe additions. 

All instrumentation was purchased by Kruse Controls, Inc. and installed as a turn-key project. The process equipment was all located in a hazardous (Class 1, Division 2) location. The entire system was validated for IQ, OQ and PQ qualifications.
