Reflux Still For Small-Scale ETOH Reproofing

Do you pull azeo right off the wash or do a stripping run first?

Depends on the price of sugar which fluctuates. I’d say roughly $70-$80 (on the high end) though which includes sugar, yeast and yeast nutrients.

I have heard of people using corn syrup instead to try to offset the cost of sugar, but I’m unsure what ratio they use of corn syrup to get an equivalent amount of sugar in their wash as using straight up sugar. Or if they’re even really saving much money.

Yes I do, but you can do a few stripping runs first and run it that way. If you were making it to drink that’d be the way to go but for our purposes it isn’t necessary.

10 a gallon is much cheaper than 55 a gallon lol I might just go this route instead of buying 190 retail

If you have good column the 10% wash is fine to run to azeotropic without a stripping run. It’ll save you some time and $$ in energy cost. Though its easier to do a strip to rectification run especially when you’re first starting out.

Until you’re buying 1000gal at a time it’ll always be cheaper to make it yourself.

Look for any sugar source, malt extract, corn syrup, whatever’s cheapest per kcal!

I hear post extraction biomass is cheap…

haven’t figured out how to make liquor with it yet.
but I believe we’ve got a working assay for our cellulase(s) (glucose production), so we’re making progress.

Yup! You need to 140c steam + acid treat it to get it to an efficient extraction potential from what it heard? I’m sure you can get less results with lower steam temps.

I wonder how annoying the filtration would be

trying to avoid that route…using a biologists toolkit rather than a chemists.

the only reason we have peak oil is that the white rot fungi figured out how to eat dead trees. selection is a powerful tool. fungi, are supremely adapted to seeking new food sources.

I like where this is going :stuck_out_tongue_winking_eye:
Will I get my answers googling hemp cellulose fungi and digging around? Or am I going to need some more expertise digging up this answer? :slight_smile:

Is there any specifics white rot strains?

I’m gonna guess that query will simply bring you back here :wink:

I’m terrible with names, once you make them Latin, it gets worse. Paul Stametes has done some work on the subject, but did not seem interested in the hemp aspect when I tried pitching a joint effort on the subject. I was chatting with his nextdoor neighbor yesterday, and it might be an anti-cannabis thing. Dunno.

Convincing the feds that psilocybes are required to effectively scale cellulosic ethanol would be a major boost to the https://psi-2020.org campaign :slight_smile:

They are in fact a white rot fungus

Hhahaha, just called up my most fungally inclined friend. His thoughts; ā€œI think this kinda thing is only useful on scale… But you might as well just use sawdust if you’re after cellulose. But if you’re gonna put the time in to distill something you might as well just buy some barley or sugar and save yourself the headacheā€

So he thinks it’s doable. But there’s no shortage of cheap cellulose.

My fear was you’d Max out at 1-2% alcohol in your wash with some super rank smells and compounds going along for the ride.

In which case I’m turning spent hemp into fuel, which still seems like a win.

And there is a shortage of cheap fuel…

8 bubble plates might be too high for my basement ceiling lol might need to cut it down to 6 or 7 plates. Also im thinking about going to a 6" column not 4" for speed/throughput. this is for a single wall boiler

would not be getting that infusion pot Gin basket thing attached to the top

If you are looking to produce azeo, a packed column rather than plates is your best bet.

The boozer in me really wants that gin box that’s totally unnecessary for our application… Actually, that entire setup would be a great excuse to make the dreams of 19 year old me finally come true. On the company dime no less! :heart_eyes:

Side note, maybe someone with more experience running a coolant managed system can correct me, but that reflux condenser looks a little short to keep up with that size still…
