Hello,
I am working on an automatic brewery that runs unattended until just before transfer to fermenter.
I thought of an way to prevent boil over and thought I would ask about it.
What if I take a lid for my boil kettle, drill small holes around the perimeter, cut a large duct size hole in the center, weld a stainless tube to the center hole forming a top-hat looking lid. Then run an exhaust fan to the pipe.
Air would be drawn in along the edges of the lid and pulled up the center pipe.
Foam would collect toward the center and maybe travel up the pipe a little, but not boil over.
Also, I was thinking out of curiosity if the draw of the fan would cause the foam to want to break earlier (sort of like when you pull the lid off of a boiling pasta pot, the foam breaks with the lower pressure).
What do you think?
