Hi there, I operate a brewery in Brazil and we are experiencing some issues with boilover, our kettle has a total volume of 16 bbl and we boil 14 in order to end with a volume of ~12 barrels.
We can not, under any circunstance, evaporate more than 3,5% per hour due to boil over. As soon as we increase the steam trying to achieve that rate boilover becomes an issue.
We have already tried to boil with the whirpool on, trying to move the fluid away from the heating source, but that only increased a little and is not very effective in trying to get our evaporation rate up to 7-8% as intended.
We are considering using fermcap, as an anti-foam, but we also do contract brewing and some brands are not very happy with that idea claiming it might affect the quality of the final beer. Also, looking at some kettle designs - specifically with the internal heater, I started to wonder if circulating through the CIP balls would help avoiding the boil over.
Would be very interested in hearing your thoughts on the matter.
Cheers
Bruno
