CIP problem
(OP)
Hi guys!
I have a problem related to the foaming generation in NaOH 2% storage tank inside of small CIP system.
The alkal based solution is heated on 80oC, and after cleaning procedure, the foam is generated inside of the tank.
Has anyone encountered this kind of problem?
Do you have any recommendation where to start to come up with the solution?
Regards,
Ian.

The CIP is being used for raw milk process equipment cleaning. The piping between CIP plant and vertical storage tanks (50 m3 each) is DN50, and is 100 meters long.

My first guess would be to try something else that does not saponify the butter as well as NaOH. Milk is slightly acidic, so I see why NaOH was tried first. I bet you can find a proven solution by networking with others in the dairy industry.
Good luck,

In lieu of phosphoric acid cleaner I would take a look at Glycolic Acid from Dupont.
Both Dupont and Dow have outstanding technical support.
There are a lot of approved dairy cleaners, both acidic and basic, on the market you might want to look at them.

RE: CIP problem
I want to thank you for participating into this small discussion. I think that I finally found out the problems.
During raw milk separation process, some quantity of fat remained into the pipeline. In contact with caustic detergent, without proper rinsing, foam was generated.
But that was not the only problem. The one of the sealings of return pump was not tightened enough, so during recirculation, the air came into the solution. Combining both issues, foam was generated.
For now, we are dosing anti foam agent into caustic detergent tank.
I hope that this short email will help some of the members. Thank you all for support and taking part into discussion.
With kind regards,
Ian.
