7. POST-SAMPLING CLEANING
Immediately after the sample is taken the valve must be cleaned, before the product dries up inside the
valve, making it much more difficult to clean at a later stage.
16. After having taken the sample remove the
top cap and place it in alcohol
17. Connect the Recirculator’s supply hose to
the valve’s top port
18. Squeeze the hand pump completely 3-4
times to flush the valve chamber
This step is similar to Step 8.
The purpose is to flush the valve chamber and remove any product residues from the sampling process.
In this way you minimize the amount of product being circulated during the CIP process (steps 9-10).
At the same time, you should clean and disinfect the caps and make them ready to use for plugging the
ports (unless you use “new” re-useable caps, in which case you discard the used caps).
19. Connect return hose to lower port
20. Squeeze hand pump 2-3 times to circulate
the cleaning agent in the sampling valve
This is a step similar to Step 9 and 10, providing a CIP after the sampling.
Depending on the level of contamination and the hygiene requirements Steps 19-20 may be skipped.
The product being remove from the valve chamber and ports is suspended or dissolved in the alcohol
during CIP.
Your hygienic requirements and your actual application are determining factors as to whether the alco-
hol may be reused for the next CIP and if so, for how many times.
