question would this work

The main thing would be to have the inlet pipe for the aqueous phase extending inside the column a little way below the outlet port for the naphtha. Silicone would be good for pipes that need to be flexible, but the chemical compatibility and resistance of the particular cure type of the silicone should be checked beforehand - iirc, platinum cured is best. Polypropylene may also be acceptable where semi-rigid pipes would be OK.

Overhead stirring would be a lot simpler, indeed!

The principle of the design is just that naphtha gets drawn slowly up a pipe while denser, more viscous, basic sludge drops down through it. Getting the balance correct in there is about 90% of the job. I've cobbled together a few things over the years, but not this one. It became apparent that the operational parameters of any given design sometimes can be surprisingly unforgiving! It would be great if you managed to make prototype, especially with the help of your glassblower friend.

yea i have to reach out he’s a friend of a friend or hey always take the 2-3 couple hour classes learn. get equipt with equipment. boom.

So, that's a distillation set-up… Second from right is the Liebig condenser. If the inner tube was thinner, it would be a matter of slicing off the whole thing just above the lower water inlet spigot and then - somehow - breaking off the inner tube at about an inch below the level of the upper spigot.

That seems impracticable, so it would be necessary to first detach the outer tube (cut or melt) nearer the top, close enough to the spigot but not too close to reattach it, after cutting off the inner tube at the desired length by melting and and pulling it out to form a bit of a nozzle, not too narrow if bark sludge is being pumped through it.

The upper ground glass joint would need a gas inlet adapter for attaching the inlet pipe. You could use the vacuum receiver adapter (bent thing on the left above the red clips) along with a stopper for this, but a dedicated gas inlet adapter would be better. [Edit: I've noticed, the cut of bottom end of the condenser could be reworked into an inlet adapter.]

I should probably make a sketch, eh? If you're still interested in the counter-flow column, that is. I appreciate, we've veered quite wildly away from domestic appliances and into laboratory glassblowing instead, and I'm not sure how well glass from Temu would hold up to that treatment - good job you know a glassblower.

yea if you could sketch it out. my boy will figure out the rest. and get a proto back here within a short period of time( meaning as soon as possible which means don’t know a ETA) haha. will def work on making it happen

yes temu is a site i browse quite often for some reason. i have gave it chances with some items its. 50/50 so far. meaning some things are actually good and some are crap

Here it is, I've tried to make it as self-explanatory as possible as well as corresponding to the written scheme, above.

Steps 5, 6, 7 are the rework of the cut off bottom section into an inlet adapter. An option for step 5 would be to chop off the top ground glass joint and replace it with the spigot from the bottom, but that's a bit fiddly.

Step 7 is that the leftover spigot could be joined onto the narrower inside tube of the cut off bottom section if it seems it would maka a better hose connection, but you'll likely want to avoid an additional pinch point if you're pumping sludge through it.

Good luck, further questions are welcome - and remember, this is a fun idea where I can't guarantee that it absolutely will work straight from the drawing board!

PVC will leach plasticizers, you have to be aware of how that may affect your application. Fine for a proof-of-concept, less good for a finished product.

It's worth noting that you would need secondary containment when running this, in case any of the pipes come loose. A large tote box would do. You don't want to be squirting either of the two liquids around the room.

A further thought for consideration - given the flow rates of the two liquids needing to be fairly low, there's a time constraint that directly impacts how worthwhile this whole idea would be when compared with, say, just stirring the mixture with a spoon.

A further consideration is the hold-up volume, that is to say, just how much of the liquids would be sitting in the pipes. Spoons win again on this count!

It's beginning to feel like the idea has little more than novelty value :LOL:
I hope that discussing the design process has been of value all the same.

yea totally. i was just going to make a prototype. not use it. but you sparked my brain i just need a overhead stirrer and i totally understand your reasoning. cost time and bulk brief case hahaha plays a role too and space. another question since your around. regular buchner sep funnel set up vs buchner w/ vacuum and sep funnel setup? idea is to decant faster i suppose or pump into a seperate glassware not worrying about small drops of base. heat in a water bath then let cool pour into büchner funnel with filter into sep funnel. sep funnel into (or into another sep funnel drain, swirl settle separate) water wash glassware. then pull

With the simplified scheme, I don't really see the need for lab gear at all. I suppose just a sep funnel would make it easier to separate the washed naphtha from the wash water. Buchner seems superfluous and makes one more thing to wash up!

okay so. pretty much just pull to a glassware then heat water bath transfer to media bottle while cooling add 110°-125° F water to sep funnel pour room temp nps into sep funnel swirl say for 10-30seconds settle sep into dish. i mean my buddy’s setup now is pretty much that with out the sep funnel he just added it to his equipment so gunna try what you have mentioned. thanks traveler

here i go again. your concept but for washing would be legit. run it with a insta hot water system set at like 120 some how pump the saturated solvent threw the water to wash it. mmmmm

hey would this work in the factory of organic extraction category ?

Nice bit of kit, good for solvent recovery but arguably overkill for the home extraction lab. Maybe useful for stripping solvent off crude extracts of plant material, so it would be good to have if processing a large number of candidate plants.

say 500 of a candidate plant would strip some nice crystallines with some nps.

More that you'd reduce down to a smaller amount of crude extract for further purification, but not excluding crystal formation if you're lucky. Getting crystals back out of the evaporation flask might be annoying, though 😁

transformer always coming threw. i’m glad 🙂 i have this space 🪐 to throw my questions off in the air trying to think of a machine i can just add what i need to it and do everything flip the switch on like a krispy cream donut factory. come back and there’s a glass dish of that lovely

If you're after something that's basically automatic, consider building a supercritical CO2 extractor.
