Before I start, yes I know I need to discuss with my chemical provider about the frequency of when to re-prep, but I'm reaching out to peers to see what their SOPs are regarding re-prep. Our current chemical process goes back to when we first started, 22 years ago, and instead of following the mindset of "that's how we always did it," I want to find out how to do it better and the most cost effective way so I can discuss with my provider about other practices within our industry. I'm most interested in FV and brewhouse CIP. Our process is as follows:
Brewhouse 120bbl, 4 vessel with internal calandria:
Caustic prepped to 100mS (2%) w/ added oxidizer in boil kettle
Rinse
PhosNit acid prepped to 16mS (.5%)
Rinse
This is done every 10-15 brews, depending on production needs.
FVs:
When beer is filtered, tank is purged of CO2 to about 1000ppm.
Caustic prepped to 70mS (1.5%)
Rinse w/ hot water.
PhosNit acid is ran every 4 turns of the tank. (this was recently implemented after discussing with several breweries who run a turn based system for acid on tanks.)
Our current process is to run Brewhouse CIP at the end of the week, then re-prep all chemicals for the start of the next week. What's everyone else doing? Are you all getting more out of your chemicals?
Thanks,
Aaron
