How do you manage swabbing internal product surfaces of pipes conveying dry RTE product? Looking for options that involve not cutting out a dozen access doors for sampling!

How do you clean them?  At what frequency?

 

Is your micro sampling significantly more frequent than your cleaning cycle?

Hi Ananiah Blessing,

 

 

Welcome to the IFSQN forums

 

As G M has indicated you would swab after cleaning. With dry products, this may not be particularly frequent unless necessary for something like an allergen change.

 

A deterioration in product micro results would suggest an issue that warrants cleaning & swabbing. In powder manufacturing we used Microbial Trend Analysis (MTA) to determine levels of contamination and the need for cleaning. This is a better and more hygienic option IMO than breaking open equipment/plant to sample/swab.

 

Kind regards,
