Is it viable to place combined cooks in to a large 'wide surface area' tub and leave for several weeks/months for natural evaporation?

This would save on energy expenditure and the smell that comes with reducing cooks.

Is there anything to do with physics that may hinder this? IE, tannins in the water not allowing standard evaporation rates?

The only problem I see here is possible contamination with bacteria, mold etc. over time. This might ruin some of the active components.

Technically speaking, the tea will boil slightly above 100 °C since there are dissolved salts in the water, rising the b.p. However, I don't think this affects evaporation rate in any significant way.

Fans and gentle heating will speed up the evaporation process significantly (water cools down by evaporation so slight heating adjusts for that).

One way people get around using lots of water is to use another solvent, such as alcohol, acetone. They use Soxhlet extractor to recycle the solvent needing less of it. Or they reflux the solvent instead of boiling large amount of it.

If you watch some extraction factories (for cannabis for example), you might see huge rotary evaporators. This is where they concentrate their extracts. Rotavaps are designed to make the evaporation very fast and efficient.

You can also use small amount of water, extract that and repeat the process instead of combining the cooks (cookings?).

Thanks for replying.

I was thinking pop a water purification tablet in there, or something else to that effect.

I always thought that the hotter the solution is and the more air moving around the surface will equate to faster evaporation.

Im curious about the Soxhlet extraction process as i primarily work with acetone/xyelene for fumarate conversion and want to remove unnecessary steps like boiling/reduction. However the Soxhlet is far too small for my requirements.
My greatest issues i want to decrease now is the pesky boil off/reduction phase, as well as the waste of acetone that occurs when salting dmt from xylene. I doubt the Soxhlet can seperate xylene and acetone. Is there anything that can? I am just evaporating acetone from my xyxlene and wasting it all so i can recycle the xyxlene.

Just in case ... have you considered STB? No boil, no mess, no waste of anything but lye when doing extraction=>mini-A(salting)/B(re-x)=>FASA

A fan is a highly effective way to dry things as well.

Im afraid this isnt viable, both because my material isnt not 1% (more like .05% if i'm lucky and so my volumes are greater as a result) and because of emlusion issues.

As in a fan on its own with out a heat source? yeah, although costly to run for many days/weeks because that's how long evaporation would take if the solution wasnt heated. Would probably equal out to be the same cost as setting it up over a boiler and using the fan for 5 hours.
