Hi all,
In trying to optimize our use of chemicals at the brewery, I've been reading a bit of research on the topic. Apparently, for cleaning CCT's, a solution of 1% NaOH might be enough to get it clean, if a proper pre-rinse has been executed.
I was wondering: what concentrations of caustic does everyone use for different parts of the brewery, in particular:
FV's
heat exchangers
bottling line
and with which frequency are they cleaned with caustic and acid? And why?
At the moment, we flush FV's with hot water, then pre-rinse with about 0,5% caustic (5 min cycle), then do our actual caustic cycle with 2% @ 70 degrees celsius, rinse with water, then PAA 0,5%. This same SOP goes for all in the brewery, minus the caustic pre-rinse.
I'd like to get the amount of caustic used down to a minimum, whilst keeping the quality of cleaning high.
Thanks & cheers,
Allard
