Just got my paws on 2 Perlick Gas Blenders built into a rig coming from a set of CO2 and Nitrogen regulators. Stout Heaven here I come! 75/25, 60/40 - I'll be able to adjust to whatever the recipe is best served with!
Image is below courtesy of Annapolis Homebrew. They retail for about $300 each. Snagged a pair along with all regulators and distribution for less than 300... You set the incoming Nitrogen at 30SCFM and the incoming CO2 at 15SCFM for a perfect 75/25 beer gas (with both primary regulators set at 40psi matched).
the key is the INLET gas pressure coming from the two independent primary regulators has to be matched. For the Perlick you match them at 40psi.
There of course has to be flow...... In a very low flow situation, the orifices are not going to be able to proportion the gas properly because the flow will not be high enough to be effected by the restriction. This is going to work for pressurizing a keg initially, but once it's pressurized and the flow drops to near zero it isn't going to proportion the gasses properly.
