Hybrid stills.

Bubble-Pot? Pot-Column? Bubble- Packed column? Don't know quite what it is?
Here is the place for the weird and the wonderful.

I agree, it would however be a "heads up" if you were otherwise distracted logging info., shuffling jars etc.. I for one haven't run my hybrid that often and until it becomes more or less instinctual any tips I can gleen from others experience I'll sock away. ;)

As much as we don't (or shouldn't) rely on temp to make the tails cut, we shouldn't rely on fog to make cuts either.


What about those of us that don't use thermometers? :mrgreen:

Use the nose, it always knows

You didn't need me to tell you that PP.

I think fogging is a handy tool. It would be interesting to see it you get repeatable and/or predictable results that you could make cuts by.

:shock: Whaaaat? :mrgreen:

I agree if we could get it to that point. It would be a neat tool to have.

I am not thinking this will ever be exact science but more of a reference....to see in the distilling process...

I don't have 10 sight glasses to observe with... but i think if i did i would place a couple above the deflagmator and prior to the condenser just to see how and when they do fog up in relation to whats coming out in the parrot.. but i am thinking more or the fogging when H20 vapor hits somewhere near the end or the run might be a set point in the H20/ethanol ratio...


of course chilling the lens or sudden temp changes or cold weather could and would effect the fogging due to the changing dew point on the glass, and a hot or heated glass would never fog...

so some variables do exist in this

Mine is pretty damn hot when it fogs up at the end of a run? So I'm not sure what was ment by that statement?

If the glass is warmer than the gas within will never fog up... the dewpoint is in the gas not on the surface of the glass. If the glass is colder as if from outside air cooling it more rapidly than the housings then condensate would form on the glass inside surface...

Ok I got you now. Hotter then the gas inside the column. Which it will never be hotter. Because its being heated by those vapors. And it will always be cooler outside the column.

Sory just wasn't picking up what you were laying down.

I'm all good here... Knew it was dryer at the start more ABV as it depletes more water vapor hence the fogging ... but at what point does it fog is the 64,000 dollar question

Sorry if I am get this to far off topic!


Don't worry about it Ben. This thread is all off topic to what I originally posted it for. But is becoming very good with all the different talk about these stills.

Bent,

And thats repetitive regardless of running speed? On those two set ups?

I gotta ask, can anyone say what the fog is? That is, whats its composition?

Is it a small fraction of the tails (like methonol and acetone are some of the fores). Maybe something before or after the fussel oils?

It seems to clear once the water vapor appears

EG I would think its whatevers in the area at the time. I would think mainly water. Methanol should be gone by the end of the run. And mine stays fogged up till after I shut it off and it cools.

just finished a TPW run with 4 plates & a 500mm ss scrubby packed 4" section on top. ended up with about 10l hearts @95% :D

Like my previous run this one also fogged the site glasses from the bottom up. Was still pulling 95% when the top glass started to fog. Pulled about 1l from then until it hit 20%.

Seems like tails also get pretty well compressed using these units.

Gotta say I'm a happy camper :)

edit" - forgot to add, I agree with Prarie - I think it's mostly water as before fogging started alcohol "legs" were running down the glass. soon after i could see droplets forming on the inside of the t (on the stain) fogging would start on the glass & droplets then formed on the glass.

So CD when the fog formed using your unit were you in tails already or just getting ready to start them...

IF it repeats next few runs you may have a reference point to somewhat go by...

Hi FS,
Just like the last run, hearts were still coming out when the bottom plate started to fog. I collected some more before swapping jars as the alchometer was still reading 95% & clean smelling product was coming out. After that, Tails took a bit longer to come through i.e. while the 2nd then 3rd plate fogged. It was pretty quick once the top plate fogged, then the ABV dropped real quick but I only got about 1l from 94% - 20%.

reckon you're right re reference, but with 21l voddie on hand after yesterday - it might be a little while before i need to do another run. Doesn't mean i don't want to or will :lol: it'll have to wait till i got some fermenter space free - unless i buy another fermenter....

CD,
I think you may see something similar regardless of what product your running as long as you using a similar set up... Keep monitoring it...

It's sometimes hard to keep meaningful results when its a while in between.

I would think it would be lower then 40%. I'm thinking 10% or so. But I have nothing to base this on other then a gut feeling.

What makes you think 40%? Just curious.

I'm wishing I would have added that liquid takeoff at the plate.

Hi FS,

using the hybrid purely for neutral so far. drinking some ATM & happy as.

Gotta admit I haven't run it as a 4 plater yet - ran out of time. Next time I'm home the rum and ujsm should be ready. Interested to see if a similar result occurs then. Thinking about running some of the rum through the hybrid for a white.

Will keep everyone informed as I'm documenting each run ATM until I get the hang of different setups.
Cheers

Hybrid stills are generally a combination of pot and column stills interlinked with piping, instruments and diverter valves. Simple pot stills for example will produce more robust flavours than a hybrid still- pros and cons with each. Greater control over flavour and aromatics in a hybrid still. Hybrid stills in theory are more efficient in terms of yield than simple pot stills. Hybrid stills are, from my experience, cheaper to buy.
