Industries subject to compliance with the strictest hygiene standards, such as the food industry, have been converting for decades to cleaning-in-place (CIP) systems to clean their process equipment.
Due to the efficiency and reliability of the process in ultra-sensitive areas, the fields of application of CIP are constantly expanding.
What cleaning is in place? What are the benefits? How does the cleaning process take place in a CIP installation?
We will explain everything to you.
The main objective of a CIP system is that it achieves the desired level of cleanliness without any dismantling of the process equipment.
What cleaning is in place?
Clean-in-place (CIP)* refers to an automatic cleaning process for processing and production facilities. The industrial cleaning process is directly integrated into the equipment during their design (tanks, reservoirs, reactors, containers, etc.).
They are then washed without dismantling continuously or cyclically. The process is carried out thanks to the circulation of cleaning solutions in pumps, pipes, valves, etc., which distribute the solutions (cleaning solutions, rinsing solutions, disinfection solutions) on the various surfaces of the machines.
CIP systems exercise constant control of the parameters retained (time, action, concentration of detergent, temperature)** in the automated cleaning processes, which makes it possible to obtain constant professional cleaning performance.
CIP systems were already available around fifty years ago. Originally, they were used by professionals in the food industry where they quickly demonstrated their effectiveness. They also use the 1-product cleaning and disinfection unit as a fixed hygiene station .
They are subsequently introduced into many fields and many equally demanding and hygienic processing facilities: pharmaceutical industry, chemical industry, oil and gas industry, cosmetics, dairy, brewery, etc.

The benefits of a clean-in-place (CIP) system?
The professional advantages of using CIP are numerous:
- Reduces consumption of water, detergents, and disinfectants
- Manages all cleaning and decontamination functions…
- Reduces operating costs: cleaning, maintenance, energy, wastewater, etc.
- Allows intervention immediately after production
- Avoid heat loss
- Reduces water consumption
- Produces little waste
- Provides maximum cleaning efficiency
- Ensures minimal risk for operators
- Reduces microbial risk
- Guarantees compliance with the strictest hygiene standards
- Ensures faster setup times
- Improves production capacities
What are the steps of an automated clean-in-place (CIP) system?
The CIP differs according to the products treated and the degree of contamination of the installation. A complete cleaning process usually includes the steps outlined below.
- Pre-rinse to remove coarser dirt
- Cleaning with an alkaline product or detergent
- Rinse with water to remove the cleaning solution
- Wash with acid to remove scale deposits
- Rinse with clear water
- Drying if necessary Optional
- Filling the installation with a disinfection solution to kill microorganisms
- Rinse with water to remove the disinfectant cleaner
