Meaning CIP (Cleaning-In-Place) & SIP (Sterilisation-In-Place)


CIP (Cleaning-In-Place) colloquially refers to the cleaning of mostly industrial systems on site. When cleaning on site, there is no disassembly of individual components, the entire system or the entire container. With the help of CIP cleaning, complete production plants including valves, pumps, pipes, sight glasses, sensors, etc. can be freed from product residues, usually through a multi-stage cleaning system and with different rinsing processes and cleaning substances. This cleaning process allows for an economical and time-effective cleaning on site. CIP cleaning is mainly used in hygiene-critical industrial sectors such as the pharmaceutical, food and beverage industries. Frequently, constantly changing production processes require fast and reliable cleaning. The cleaning effectiveness can be controlled with the help of sampling and sensors before and after cleaning.

The SIP (Sterilisation-In-Place) cleaning process extends the CIP cleaning by an additional sterilisation and is run over the same set-up. This sterilisation takes place after the CIP cleaning; in the procedure described above, this subsequent sterilisation was also listed. Sterilisation removes any microorganisms that may still be active from the system. Sterilisation usually takes place at a temperature of +140°C, cleaning is done with saturated clean steam, the effectiveness of this cleaning is significantly increased by the addition of chemical disinfectants.
