Cleaning in Place (CIP)

Cleaning in Place involves the cleaning of the machinery and pipework using a mixture of chemicals, heat and water without dismantling or opening equipment.

Where or why would I use Cleaning in Place?  

Cleaning in Place (CIP) is commonly used in hygiene critical industries to clean a wide range of plant equipment without opening or dismantling the equipment. CIP is an efficient way to run manufacturing operations as equipment can be cleaned rapidly in between batches with minimal disruption.

Commonplace in food and beverage processing, CIP solutions are often a Critical Control Point (CCP) which must be monitored.

What are the most common sanitisers for use with Cleaning in Place systems?

There are a number of sanitisers and sanitising techniques used in Cleaning-in-Place solutions. Popular sanitisers include chlorine, chlorine dioxide, PAA and ozone. There is no industry-wide standard and the use of a sanitiser will vary depending on the producer, process, buyer and regulator.

Chlorine is a very low-cost sanitiser and is widely used for CIP systems. However, chlorine can corrode Stainless Steel in high concentrations and is a risk to personnel.

Chlorine dioxide is known to be an effective sanitiser for use in CIP systems, especially as it does not have many odour or taste implications for the final product. However as a slightly more expensive sanitiser, this does not have the same widespread usage as chlorine.

Ozone does not leave a residual or by-products after disinfection in CIP processes. The use of ozone may eliminate the need of some hot water cycles, reducing the amount of water used, and the energy costs associated with hot water.

PAA is a powerful oxidising agent with an oxidation capacity higher than sodium hypochlorite and chlorine dioxide and is comparable to the oxidative capacity of ozone.

What control procedures do I need for Cleaning in Place solutions?

Cleaning-in-place (CIP) involves precision techniques. Sanitiser levels must be within the correct range to ensure that the system can operate effectively and to safeguard the quality of the end produce. Many process control and HACCP procedures will prescribe the concentration and type of sanitiser to be used. The implementation of this process will require it to be recorded and acted on accordingly.
