CO2 when dumping yeast
« on: February 16, 2015, 04:14:13 pm »
How many of you with conicals hook CO2 to the top of the vessel when dumping yeast in order to avoid introducing oxygen?

I have done this. Not often, but I have done it.

One other thing - if you are harvesting yeast from the dump valve, a little pressure (2 PSI) on top makes the densest yeast come out. Once that is done the closed transfers to kegs go much faster, especially for the second keg if you have a 14.5 gallon conical.

I do, but be very careful with the pressure. I blew the lid office once and could have been injured. I built a low pressure regulator to ensure it never happened again.

Yes, over pressurizing a vessel can be very dangerous.

The Blichmann is rated at 3 PSI, I only use 2 when doing this.
