In The Shed Today

[Professor Green]

That's a great mill woodduck.

Cheers,
Prof. Green.

Yep it does a bloody good job and quick to boot. It's a commercial one I borrow off my mate every now and then. I mill some tucka for the pigs and sheep then run a few bags through for myself.

Was thinking as I was running WBAB through my reflux, if there is a correlation between vapour temperature in the reflux tower and the percentage alcohol collected.
Boiling points of the main parts of the vapour are alcohol at 78.37 and water at 100, so the vapour temp would be a calculation based on the percentages of each
Formula
Strength of distillate = -4.623209*vapour temp-462.320851

Nice calculations but, what if your input energy spikes or the temp of your cooling water changes, or passive reflux increases due to a breeze.. unfortunately, unless you ran your still in a complete vaccum then there’s no formula that could possibly control all the variables.

True, but when it is running smooothly the formula works!

Reckon a parrot will give a pretty good ABV indication straight off the still ;-)

[db1979]

It will vary with pressure. Pressure can be measured but this is far more complicated than it needs to be. As Sam said, just use a parrot.

Trying to run a 6" on only 3600w :angry-banghead: not gonna happen, no where near enough power. 3600 is only enough to reflux not for take off. Looks like it's gonna be a strip run now. Never leave power cords plugged in! Someone will turn it on and cook ya element :angry-banghead:

couple of hours in citric acid mix and a bit of a scrub came up 100%

Looks good Astro :handgestures-thumbupleft: is that a copper funnel? Did you build it or buy it?

Yes mate its a copper funnel, purchased it a few years ago now off this site

Sweet funnel is it pressed?

Spun by the looks

Could you run your 3600 flat out and use the controller on the 2400 element? Even if it were dialed right down

[woodduck]

The 2400w is buggered, I left it plugged in but the switch turned off and my workman turned it on thinking it was a different cord and cooked the element :angry-banghead:

I usually leave 2400 on and control 3600 but you've got a point there, the 2400 would give a smaller power increase/decrease wouldn't it giving me finer adjustment :-B :think:

spun mate, wish i had a few more

Nothing fancy but thought it might be handy for someone else at some time.
In my 1000 litre ibc I have a huge pond pump that I brought from masters when they were closing down, can't remember the exact specs but it pumps as good as town pressure. Anyway I found when I did a stripping run on my pot still using the ibc for cooling the output distillate was always very warm, I tried a strip run on town water and spent a bit of time playing with the water flow. Long story short at low flow I had a cooler distillate temp as the water spent more time in the condenser because it was moving slower.
So I brought one of these

it allows me to slow the flow of water out of my ibc, distillate temp is now cool to the touch no matter how hard I run the element on a strip run.

Putting my still together in is glorious entirety for the first time :happy-partydance:

Don't forget, pics or it never happened!
