Goss gas Pressure
J-ROD
Would anyone that is using or has used a goss bp-3 on a Roaster Rob type roaster be willing to share what kind of gas pressure they have ran? I'm looking to roast in the 2.5-5 pound range finished. Just trying to decide whether to get the Goss regulator or one of those 30 psi types.... I've only roasted electric so I don't know. I do not want to reinvent a very well balanced wheel, just to use what I have locally available. Thanks in advance!

Jarrett, I can't help you with the Goss, but I have a Sieverts and homemade burner about the same size and I run mine at 1-3 psi. The orifice determines the pressure range. If the flame comes out the burner and then silently turns upward the pressure is too low. If the flame is long, blue, well-formed and makes a whoosing sound, it is just right. If the flame sounds like a jet engine and the base of the flame is outside the burner, the pressure is too high.

If the "just right" flame is too hot or too cold for your roasting, then change the orifice size.

hope this helps, Dan
1 pound electric sample roaster, 3 pound direct-flame roaster, both handmade; modified Mazzer Mini grinder, LaSpaziale Vivaldi II automatic espresso machine. When the electricity goes out I make vacpot coffee from beans ground on my Zassenhaus hand grinder, and heat the water with a teakettle on the gas range.

Thanks for sharing your experience! I will (hopefully) get to testing this weekend. If I will be operating in the 1-5 psi range that would be great. I just want to have enough power for steep ramps..... Sounds like 30 psi is plenty.
