Vessel Cleaning Systems
Rapid, effective vessel cleaning
Greaves’ CIP (Clean–in–place) solutions are used by a growing number of manufacturers across industries.
CIP improves the equipment cleaning process to reduce lost productive time and ensure consistently high quality and hygiene standards.
CIP technology also increases safety by reducing operator intervention. The degree of automation can be engineered to meet client needs by use of fully programmable automated cycles.
Environmental impact can be dramatically reduced by recovery and reuse of cleaning/sterilising fluids.

Vessel Cleaning Systems FAQ’s
- CIP – “Clean-In-Place” i.e. the mixing system has its own in-built cleaning system, designed to clean all internal spaces including vessel surfaces and mixing tools.
- SIP – “Sterilise-In-Place” i.e. the mixing system has its own in-built sterilising system designed to sterilise all internal spaces including vessel surfaces and mixing tools.
- The CIP system sprays cleaning media under high pressure through at least one spray ball, two or more if a mixer is present.
- More challenging residual materials may require high pressure MultiJet spray heads which provide greater and more focused intensity of coverage.
- In many instances a hot water/detergent solution is effective. However, many food producers default to a hot caustic soda solution.
- IPA & Ethanol can be used in some applications and some chemical producers use MEK, toluene, acetone or xylene.
- ATEX compliance must be considered when using media containing flammable solvents.
- For effective cleaning, “Cleanability” of the contact parts within the process zone is vital.
- “Cleanbility” is a key consideration at design stage. It is important all contact areas are free from bacterial “traps” and are polished to a smooth surface finish to facilitate cleaning.
- Usually 2 to 4 depending on the product and hygiene level required.
- Greaves can supply CIP cleaning systems as required. It is important to identify this requirement at the outset so hygienic design principles can be applied to all aspects of the mixing system.
- Shadowing occurs if the system design allows mixer shafts or other components to obstruct the spray pattern in the vessel, thereby limiting the effectiveness of the CIP system.
- Riboflavin testing is commonly used to confirm the effectiveness of a CIP system. Riboflavin is a vitamin which is fluorescent when in solution.
- The vessel interior is coated with a dilute Riboflavin solution, then given a brief rinse by CIP. Observation by UV light confirms complete removal or otherwise.
