CIP system covers numerous operations that combine to adequately clean all or part of a process system without having to take the system apart.
CIP systems pump cleaning, rinsing, and sanitizing solutions down the same piping channel as the product to remove product grime from interior surfaces.
CIP systems vary significantly in setup, capacity, quality, and degree of automation.
They also differ by industry. Variations in product attributes and regulatory concerns across diverse sectors affect the design of a CIP system.
We control the CIP systems design at Cedar Stone by generating just enough heat to do the job.
Explaining The CIP System
CIP (Clean-in-Place) systems aim to clean and disinfect production machines and tools without removing them from use.
The procedure entails a chain of operations in which chemicals, heat, and water are used to clean the insides of storage tanks, pipes, and other machinery from buildups of dirt, debris, and microorganisms.
The Basic Stages Of A CIP Are As Follows:
- The apparatus is given preliminary water rinsing to remove any substantial dirt or debris.
- A cleaning solution with an alkaline detergent is sent through the machinery to dissolve and remove protein, fat, and oil residues.
- Water is used as an intermediate rinse to eliminate any trace of cleaning solution from the apparatus.
- An acidic cleaning solution is run through the machinery to get rid of minerals and other inorganic buildups.
- The process is finished by giving the tools one last water rinse to eliminate any trace of the cleaning agent.
- Circulating a sanitizing solution through the apparatus containing chlorine or peroxide kills any leftover bacteria.
- The next step is to rinse the equipment with water to eliminate lingering sanitizer.
Automated CIP systems achieve standardized and efficient cleaning using programmable logic controllers (PLCs).
The process may be tracked and tweaked as required to ensure the apparatus is thoroughly scrubbed and sterilized.
Many industries and pieces of machinery have unique cleaning needs, and the CIP method may be adjusted accordingly.
To What Four Tenets Does CIP Adhere?
1. Temperature
For proper system heating, the CIP circuit return header must be used for tracking and monitoring CIP temperatures.
Standard temperatures for CIP systems range from around 160°C to 350°F. It indicates the source header’s temperature is even greater after leaving the CIP. While developing a plan, it’s important to keep the temperature in mind.
As additional heat is introduced into a CIP system, the temperature rises. Solubility increases with temperature, making cleaning more effective at higher degrees.
This may be the case for certain applied disciplines, but when a system’s temperature rises, new complications emerge.
Accidental cavitation at pump inlets due to virtually uncontrolled boiling raises safety concerns.
A hammer will be in your pipe system if the pressure drops and the water suddenly turns to steam.
Carbonic acid is produced when moisture and condensation undergo an unintended phase transition, and this acid eats away at the pipe wall, shortening its lifespan.
As a system is heated to higher temperatures, its enthalpy, heat, and entropy, or disorder, increase.
Bring back that pressurized liquid, operating at 312°F and 80 psi. The fluid may escape at atmospheric pressure if a leak or break appears in the pipe system conveying it.
2. Chemical Concentration
The chemical concentration is often measured using a mix of metered dosage and conductivity sensors.
CIP systems use closed-loop mixing to achieve and maintain a desired chemical concentration in the solution before activating washing cycle timers.
The system’s conductivity is essential for removing any remaining chemicals before the final rinse.
Certain compounds don’t easily dissolve, even at near-boiling conditions. For this reason, it is crucial to pick the right chemicals when creating CIP systems.
Each method must be universally used. Commercial CIP systems often employ something considerably more potent to break down soils than daily soap.
3. Mechanized Intervention
Allowing components to come into contact with a hot CIP solution is usually inadequate, even if a thorough soak may loosen many soils.
Removing dirt from surfaces requires a mechanical activity, such as scrubbing.
The most common manifestations of this phenomenon are turbulence in the pipe flow and cascade in the containers.
To get into the specifics of turbulent flow would be beyond the scope of this essay, but suffice it to say that a velocity of at least five feet per second is required for efficient scrubbing action.
4. Duration
The CIP framework’s fourth and final pillar is time. It could provide good outcomes if you give a system enough time to work, even if it’s well-designed.
As expected, spending too much time on anything has a monetary cost. There is another important reason why blanket solutions seldom work.
