I am in need of your collective wisdom and guidance. I am in the midst of working on our manual CIP SSOP and cannot locate references for flow velocity and circulation times to validate or to provide to our auditors when they come in that provides rationale for our uses. I am sure we can use data logs such as negative test results, flow rate measurements, titration recordings, etc., but I am really looking for that "golden egg!" ...Or am I simply on a wild goose chase?
Background: New sauce line implemented that produces then freezes (nitrogen bath) various sauces for customers. Our CIP is manual. The flow velocity rate and circulation times used are as recommended by chemical manufacturer; however, when asked about references for recommendations, we are told this comes from years of experience and training in the industry, via email communique which I am not confident in printing and presenting to an auditor as reference. We are on the BRC track and produce both USDA and FDA items.
Links to previous threads regarding CIP that I have come across on the Forum have been helpful, but not definitive when it comes to establishing flow rates and circulation times. I would welcome and greatly appreciate any further guidance and direction!
IMEX, equipment suppliers do not automatically divulge core principles for their operational Validation Procedures since this is often competitive/confidential information except where perhaps legality factors are involved. Some procedures include "Rule-of-Thumb" formulae or spreadsheets involved which have been, long-term, developed internally.
Not my area of expertise but I seem to recall that some general basic validation requirements are covered in previous threads here which probably correlate to yr manufacturer's supplied procedures ? You may have to provide more specific quantitative information/process details as to what you are seeking to get more directly useful answers.Go to the full post
