Identification: Clean-In-Place (CIP)

Clean-In-Place (CIP)

Many manufacturing facilities require (CIP) systems to clean tanks, pumps, valves, filters, heat exchange units as well as the process piping. The use of CIP increases plant efficiency, improves safety and ensures product quality. However, achieving these benefits requires monitoring and control of the CIP process to optimize heat, cleaning agents and water consumption.

CIP Optimization

Precise process interface detection with a single channel NIR absorption based photometer (optek AF16-N or AS16-N) is typically installed at the CIP return points where it is beneficial to measure the exact interface on rinse water. Inline photometers can also be used to monitor the sanitizer concentration to control the CIP process, for validation routines, and in some cases, to monitor the residual after cleaning.

Sanitizer Concentration

Chemical concentration has always been a difficult measurement using traditional conductivity sensors. Changes in pH, temperature, or other unexpected compounds can all affect conductivity devises. To compensate for these issues, plant operators often overdose chemicals to ensure adequate sterilization, then extend line flushes to ensure it is removed.

Sanitizer Optimization

By installing an optek UV / VIS or NIR absorption sensor on the feed line, exact concentrations are monitored, optimizing performance, while reducing chemical usage. These sensors are also compensated to eliminate any influence from turbidity or the presence of other compounds. In addition, with immediate response times, sanitizer and water usage is greatly reduced.
