So, I won't get too deep into it, but MDARD was here to do an FDA full PC 3-day audit (during my xmas party, fun). Anyway, they have deemed it a requirement that we sanitize our fillers as just hot water washouts was not enough.
We have no CIP system and I'm thinking of using our kettles to heat water up in metal totes to flush through the system. Problem is, 2 of our lines are not rated for high temps and have a max of 180F allowed.
I need some more info/research links on time/temp relations for hot water sanitization. So far, I've found some conflicting info. Like:
- Temperature and duration: The water temperature should be maintained between 80-85°C, and the process should last for 15-20 minutes to ensure effective sanitization.
Which kind of conflicts with the info at the University of Minnesota which says: Water at 171°F (77°C) must be in contact with the surface for at least 15 seconds to be effective.
So based on the Uni page, I can just run water between 175/179F for 15 seconds to 'sanitize', but I'd like more research to back that up or disprove it.
