Using the BD747

Postby crow » Thu May 31, 2012 1:16 pm

ok I'm doing astrip run with the new burner . I built a kilm which was useless as it couldn't draw anough air and trapped the flame anyway its good now but I'm a bit worried how much is too much heat . I've turned it right down but its still making the bottom of the keg glow red is the stainless ok that hot

If nothing gives I'm in love . fill up a 600ml jar while typing Edit spirit is around 70 ABV EDIT 2 had to turn it down some more struggle to get 100 % vapor knock down now getting 60 ABV at 100 ml in 18 seconds does this sound ok for a strip run

Ok whats the consensus on a good ABV to cut of at on a strip I normally go for 15 to 20 % sound about right ? never thought to ask so I just went a bit lower than normal in the past EDIT ok an hr in and I'm down to 30 ABV and thats with the burner turned right down had to use a bit more water to get knock down re thinking about re circulation now EDIT 2 My over view of this burner is that it is fucking fantastic , all done in two hrs and if I hadn't of wussed out may have been over in one . Don is a dead set no bullshit legend and his burner is the bomb period ^:)^ , can and will recommend :handgestures-thumbupleft:

I was told to stop at 20%. I guess you're going to have to increase the cooling power to compensate.

Did the low wines came out nice and clear at such a fast rate?

hoping someone would ask that before me I'll take some convincing to pack mine away this burner is stiffy material , turned fully up the flame is near 1 mtr high :shock: and hot enough to hammer weld with

burning the wash to the base of the boiler is a big concern
