question about temperature

Putting older posts here. Going to try to keep the novice forum pruned about 90 days work. The 'good' old stuff is going to be put into appropriate forums.

question about temperature

Post by cornlikr »

I've built a 5 gallon stainless pot still to be run on propane, and working on a 15 gallon. I've read to not worry about thermometers and go by taste for the cuts. My question is how do you gauge how much heat to apply to the pot so it doesn't puke? I would think you could fire it harder on heat up and then cut it back, but I'm not sure when, and what I should cut it back to. Forgive me if this has been covered elsewhere.

Experience (and only fillin' yer boiler 1/3 full on a strippin' run) is how to prevent pukin'. Pukin' durin' a spirit run doesn't matter much anyways, as it's gonna get run again. Pukin' is almost non-existant durin' spirit runs.

Heat up the boiler with as much heat as ya want, but keep touchin' yer layne-arm to moniter how close the still is to bein' ready. Once the layne-arm gets too hot to touch ya know the vapour will hit the condencer any second.

Boiling chips of some kind (to break up bubbles) more head space and listen to how hard it's boiling

Yep, that's exactly what I find too, holy. Within minutes.

Kinda off topic, but was watching a food channel show from Iceland. With thier geothermal steam system, a cook took 5 gallons of water in a steam kettle from tap to boiling in 7 seconds, yes, SEVEN SECONDS :shock: My calculator had a heart attack when I tried to figure BTU's.
It is the very things that we think we know, that keep us from learning what we should know.

Yeah, I've seen that same program... Hard to believe until you see it happen... My first thoughts drifted towards distillation... Would really speed up both stripping and spirit runs... :mrgreen:
