Verifying Spray Effectiveness Visual Inspection
After each CIP cycle, the process equipment should be visually inspected to verify that the CIP program cleaned the vessel thoroughly. If areas of the tank indicate incomplete cleaning or coverage, corrective action should be taken accordingly. (a) Verify that the spray ball is still in place. (b) Check the spray ball for plugged holes, and clean as necessary. (c) Verify that the spray ball is the correct one for the application. (d) Verify that the correct flow and pressure were obtained at the spray ball. If any flow restricting orifices are used to control the flow, verify that the correct restrictors are in place. Instrument Verification and Documenting Performance Additional instrumentation may be employed to verify and/or document that the CIP cycle performed as designed. A flow meter and pressure transmitter can document that the proper flow and pressure of CIP reached the spray ball. These parameters should be verified at start-up and compared with subsequent CIP cycles to ensure that proper flow and pressure are always achieved. Riboflavin Testing In critical cleaning applications, a test protocol involving a fluorescing agent such as riboflavin may be used to verify that all areas of the vessel receive proper coverage. Consult Sani-Matic for further information on this testing.
