might try putting the 2nd element on at 25% to see what happens

When i first built my bubbler i had trouble with a dropping Abv through a run, much like a pot still.
In the end it came down to not quite enough reflux and in part running it outside in the cold night air. Too much heat was getting lost. Needed more heat.
Now i run a 2400w element flat out and the other partially on with a volt controller.
Perhaps your element isnt doing you any favours here either?


Hey Dans.brew :text-+1:
Thats also been the train of thought as the element has lost 200 watts in punch, so might try the 2nd element at 25%. Just need to change one thing at a time otherwise you loose track of what the final result is. Couple of things to work on. Can't do much else until "Dan" opens up Victoria.


:angry-banghead: :angry-banghead: 8-} :violence-smack:
Guess what. Looking at my notes. I see I put the 2nd element on when collecting the heads. (Yesterdays Run) Only at 25% and my ABV went from 85% to 90% it stayed at 90% until the tails came
So it is a heating issue.. More heat more reflux ratio and more ABV. Haven't in the past had to use the 2nd element on the heads etc. I think problem solved.

Good stuff... classic insight into how important note taking is in this hobby, especially if your looking for that superior spirit... all the little bits add up. :handgestures-thumbupleft:
You'll notice a bit of a jump in the flow down your downcommers now, i did.. all the stuff going down was what was more than likely holding your Abv down.

I realise your most likely using the mesh as a retainer for the rocks, but i recon it would be worth your time to make that change possible

gawd i need a new keyboard, my r is shot


RC AL Just did a feints run today (Spirit Run) Upped the heat. 1st Element 100% 2nd one 50% and plenty of water through the RC. Take off was about 2.7 LPH and got a consistant 90% from Foreshots to tails. If I upped the 2nd element to 60% flooded the top plate. I can live with 90%, but is your line of thought by changing the copper mesh to the top and scoria to the bottom I might not flood the top plate ?. Cheers

I cant guarantee anything there, the copper is a better conductor than scoria, so having it all at the top where the column is hottest just makes sense to me, plus the one less transition zone as I said earlier, not going to cost anything but time to try

Theres something amiss if you can only get 90% out of a 40% boiler charge, you may have to slow it down some more if the packing re-arrangement dosen't work out

What size is your scoria? - I finally found a rule of thumb for packing the other day in an industry pamphlet, the min size they recon is 10-12% of diameter, so It should be minimum 10-12mm for a 4" which seems to correlate to most of what i have researched from anecdotes from forums

:text-thankyoublue:
Scoria is 10mm. The frustrating part is from the onset when I first got the 4" Neutraliser I was getting 93% and it was as easy as falling off a log.
My boiler charge is 25% consistantly.
Someone suggested my alcometer might have been out, and the funny thing is I just broke the one I had been using all that time
i just got two replacements and they read the same.
I think I will just settle on 90% and save myself some anguish. :text-lol:

:text-thankyoublue:

I have just used guyross procedure and filled the plates with water, had a small drip coming out of the top glass on the T piece.
All fixed now.
This never showed up with a mirror.

Reflux for 30 mins on a spirit run, but by the time I adjust and get the heads takeoff correct it of course would be a bit longer.

I did find another issue.
How accurate are alcometers ? I thought that I had check accurately with another alcometer.
I have one with green wax and 2 with red wax. I think the one I have just started using. (greenwax) (broke my previous one)
is measuring 2% below what the other two are.
Measured them in water 2 red ones on zero, but the green on is measuring below zero.
Same brand and made in france.
Both the red ones measuring 92% green one 90%

I guess it is a bit like getting a new tape measure and comparing it to your old one. If it is not accurate it can lead to a world of pain.
We pay $10:00 for one of these and lol expect perfection. Shows how important it is to check
