Clean-In-Place (CIP) is the proven method for cleaning the internal surfaces of process equipment—without disassembly or relocation.
In food, beverage, dairy, juice, brewery, and pharmaceutical production, CIP is used to wash product-contact surfaces such as pipelines, pumps, valve bodies, tanks, and heat exchangers with controlled flow, temperature, and chemical concentration.
A well-designed CIP system delivers repeatable hygiene, reduces downtime, and minimizes the risk of secondary contamination because cleaning occurs in a closed, contained loop.
Nanjing Hjchem Equipment Co.,Ltd supplies CIP Cleaning Systems from 100L to 5000L, engineered for stable flow velocity, reliable heating, and scalable automation—so you can match cleaning intensity to your product, soil load, and regulatory requirements.
Why CIP matters in real production (not just in theory)
A typical CIP system includes:
Chemical preparation tanks (alkali tank, acid tank, hot water tank, and optional recovery tank)
Pumps, pipelines, valves, fittings
Heating components (steam/electric + heat exchanger options)
Control cabinet (HMI/PLC available for automated systems)
CIP performance is not only “chemical cleaning.” It is a combination of:
Mechanical action: maintaining sufficient flow rate and turbulence to create impact and shear on residues
Thermal action: hot water and heated cleaning solutions improve soil removal and sanitation
Chemical action: controlled dosing of alkaline/acid solutions to dissolve organic and inorganic fouling
Time control: repeatable step durations to ensure consistency across shifts and batches
When these four factors are managed by a robust CIP design, you gain measurable benefits: faster changeovers, reduced labor, lower water/steam/chemical consumption, safer operation, and longer equipment life—especially compared with manual dismantling and open cleaning.

Note: The above specifications are standard. Nanjing Hjchem Equipment Co.,Ltd can design and manufacture customized CIP systems based on your requirements. Please inform us if you have special needs.
Our CIP Cleaning System platform is modular and can be configured to suit your plant layout and process complexity:
Structure: integrated (combined/skid) or split (separated modules)
Heating: steam heating or electric heating
Control level: manual, semi-automatic, or fully automatic
Capacity: 100L / 500L / 1000L / 2000L / 3000L / 5000L, support customization
If your factory needs cleaning while production continues, multi-circuit CIP is the key. Depending on line design, we can support one to four cleaning circuits so you can clean different zones simultaneously or perform “production + cleaning” workflows to shorten total CIP time and improve responsiveness.
Advantages of Nanjing Hjchem Equipment Co.,Ltd CIP design
1.Closed-loop hygiene to reduce re-contamination
Our CIP cleaning is executed through sealed process equipment and pipelines. By keeping the cleaning route enclosed, you reduce exposure to the environment and significantly cut the probability of secondary contamination—an important operational reality for beverage and pharmaceutical-grade hygiene.
2.High automation for repeatability and audit readiness
Fully automatic CIP can automatically monitor, dose, discharge, display, and adjust cleaning media. Key parameters—time, pH, and temperature—can be automatically switched and regulated step-by-step. All operations can be recorded, supporting GMP-oriented documentation and traceability.
3.Lower operating cost through practical engineering
A compact, space-saving system reduces installation footprint and simplifies maintenance. For higher-end automation, using pneumatic diaphragm pumps for transferring concentrated acid/alkali can improve reliability and reduce maintenance frequency—directly lowering life-cycle cost.
4.Designed around cleaning effectiveness (flow velocity + heat)
Cleaning flow is not a “nice-to-have.” It is the mechanism that creates turbulence and mechanical action. Our systems are engineered to maintain the flow conditions required to generate effective impact and cleaning results. Heated cleaning solutions further improve cleaning and disinfection outcomes.
Frequently Asked Questions (FAQ)
1.What is a CIP cleaning system used for?
It cleans product-contact surfaces inside tanks, pipelines, pumps, valves, and heat exchangers without dismantling equipment.
2.Why is flow rate important in CIP?
Flow rate ensures sufficient velocity and turbulence, creating mechanical impact that improves residue removal and cleaning effectiveness.
3. Can I clean while production continues?
Yes. With multi-circuit designs (2–4 circuits), zones can be cleaned in parallel and cleaning can be coordinated with production.
4. What control modes are available?
Manual, semi-automatic, and fully automatic. Fully automatic systems can monitor and adjust time, pH, and temperature and keep operation records.
5. What capacity should I choose—100L or 5000L?
It depends on your circuit volume, number of lines, cleaning time targets, and whether you need parallel cleaning zones. We can size it from your P&ID.
6.Which industries commonly use CIP?
Food and beverage, dairy, juice, brewery, and pharmaceutical processing—anywhere hygiene and repeatability are critical.
