How long does it take the everclear to evaporate?

No, longer in the freezer isn't a problem. Longer is actually better, but there are diminishing returns.

That's such a crazy cold vacuum environment. At 29.5 hg. Does the liquid splash all over the place in the chamber?
I've done 60F vacuum boils. And tend to get lots of splashing..
P.s. I was so fortunate enough today to meet a fellow oil maker that has really studied the skunk farm recovery systems. I really do fancy the closed system!

Interestingly, under vacuum alcohol doesn't rapidly boil, but mostly just evaporates as a gas from the surface, as the gas is not produced from sub surface heating.
If you degas the alcohol solution carefully first, by just holding at vacuum until the violent bubbling stops, 115F and -29.5 leaves only the occasional bumping from the alcohol, when a point of nucleation sudden release a large bubble.
We mostly cold boil in a Pyrex casserole dish with a sheet of DS tempered glass sitting on top. The bumping bubbles will deposit on the glass and not the chamber walls. It drys there and is easy to remove.
A closed system is definitely the way to go from a safety and cost per gram to process standpoint. It is refreshing to see the idea catching on like wild fire, with Mk IIIA's going out to the four corners and a lineup behind the Mk V prototype. Best yet, there is a plethora of bright minds taking the idea and working hard to develop it to the next level. Both from an equipment design standpoint, but the process as well.
Would this technique also work with dry material pulled out of the extraction contraption?
My thought would be to mix x amount of product with x amount of alcohol to get a product that I could then winterize per the specs you've listed?
I would likely strain the mixed solution thru a coffee filter as well?

Fadedawg, would you please elaborate on your setup for cold boiling? Are you capturing the alcohol as it evaporates and condensing it? Does it pass through the pump, would a special pump be necessary because of that?
Thanks

A good question, which I deferred to biotech Pharmer Joe, who says atmospheric pressure would affect decarboxylation rates, but couldn't offer any empirical numbers.

We found around 48 hours about the point of diminishing returns, but it doesn't damage the product to do it ten times that long. I've forgotten jars of solution in the freezer for months, and still produced pristine material when I finished it off. In those cases, the wax was already coating the bottom of the jar, as opposed to hanging in suspension.

Not as long as the alcohol isnt too low, it is still evaporating in there.... very slowly... so... yea id draw the line @ 3 days depending on batch size

I put a lid on the jar of alcohol and oil in the freezer, so evaporation is nil.

air flow helps. you can hook a vacuum pump to a cold condenser to trap the alcohol before it gets to the pump and reclaim the alcohol. that speeds things up for sure.
hope this helps.

Ok so I have been getting all my Equipment together....
- CLS
- Vacuum Chamber w/ Vac and Cold Trap
- Heating Mat for Chamber (low temp and NOT full vac i know sir
) - Büchner funnel & Flask
Should i get a secondary cheaper pump to do the Everclear vac with or with the Cold Trap keep my Big Boy Pump ok? I don't mind getting a HFT cheap one just to do the Everclear vacuum with i just don't want my 7cfm Pump to get fucked up i got a good one so i could use it with a Oven when i upgrade. Also there should be no left over taste right?
Thank you GW you are a King Among Kings sir. I always share you site when people ask me about CLS or anything that has to do with Extraction at my Smokeshop.

No. At least 48 hours, but longer works. After a month in the freezer, most of the waxes will settle to the bottom of the container, instead of being suspended through out.

So i think I'm ready to try your method. Now I have a question about vacuuming of the 190 proof everclear?

A faucet aspirator will work for vacuum filtration. Unless you have a chemical duty pump, vacuum filtration dilutes your gear case and shortens pump life.

Hi fadedawg, can you point out a place where i can find more info on this? Such as equipment . TIA

You can do it in a vacuum oven in a casserole dish, covered by a sheet of glass, but the most common way is thin film techniques like the rotovape:
