CIP cleaning with caustic only
Our CIP system is set up to sanitize during the last rinse cycle after acid wash. We only do acid wash once a week, the rest of the times we only wash with caustic. Should the sanitizer be applied after every caustic wash, or is it sufficient to do it only once a week after the acid wash?
Hi Anneke,
It is possible that washing with caustic only is adequate. This would depend on your product, the level of contamination you find after a caustic wash and the length of time between washes.
Microbiological tests on first product through plant and equipment should give an indication of any issues relating to ineffective cleaning.
Kind regards,
Tony

Thank you. We produce sorbet and clean the tanks after every blend with caustic. We are now looking into changing the programming to do a sanitizer wash after every caustic cycle as well. Generally we do not have a lot of micro problems with our water, but sanitizing might help to eliminate random micro counts picked up in our end product.
Hi Anneke,
Try Peracetic Acid, it is effective and does not need to be rinsed after use
