QWET oil extraction

[Gray Wolf]

hello again, gray wolf


when you say "cold boil"...what is that..?
butane...boiling off at room temps...?


and how would the vacuum set up work..
whats it do...? function..?


thanks

Boiling under vacuum. As the atmospheric pressure is lowered using vacuum, the boiling point drops.

Here is an ethanol boiling point under vacuum chart, which I believe originally came from Skyhighler.

thanks again pal....
you are a wealth of information, my friend...


so how would one set up a vacuum situation
to cook their extract....?


is this all professional grade equipment and big $$$ to accomplish....or is there some kinda home remedy one could MacGyver.....?


also, any pictures would definitely help...
thanks,


as an after thought, look at this contraption made in china
cheap, cheap.....stainless steel still (for closed loop recovery)
its a still....copper tube winding inside...complete about $250 CAN for the 12L one....check it

Thanks for the good thoughts brother!

Yup, it is a gin, but still works good for the purpose, don't it?

How much additional wax are you recovering between the first and second filtration?

Oily and strong is about how our's typically turns out with no vacuum finish, also with a slight sweet background taste from residual ethanol. Faster to reach FDA residual solvent standards with vacuum, in addition to moderate heat.

hey there greywolf


in this post I keyed in on slight sweet taste by residual ethanol
after extraction, ....awesome


can you elaborate somewhat on this...
what kind of sweet overtone is expected...?


and does this added flavor also smell like it,
when burned up in a spliff...?


also, what kind of ethanol are we talking, I know I hear everclear a lot....
but im way up north in Canada, not in an igloo way up north....haha....but in Canada none the less...


what ethanols would I have at my disposal ?


im after flavor....with a decent yield
im always using pure bud,
ive only done several small batches in the experiment stage


thanks so much

Any subtle differences compared to using the ISO? Will it taste more of buds this way? I only used pretty old cindy buds 5 years maybe older on previous qwiso attempts. Was thinking to try this since I have some ever clear and the rest of the stuff handy.

I would do the open BHO for a trial but don't have a pump or vac chamber....

It will be fore smoking purposes as well.

got to love, smoking purposes....ahaha
im in brother....lol

Usually winterizing lowers the monoterpene content, so it tastes more diterpene "hashy."

hi again SIR Grey,




can you roughly outline the winterizing process for me
I use ISO not ethanol, im up in Canada and cant get everclear 190 proof, so for the time being stuck with ISO 99


I thought ive read before somewhere along the line
that a winterizing process can change the color to deep amber red color...is that true..?


and how would one accomplish this at home....lol

This is a photo of my latest batch of Everclear dabbage. I'm posting it because it was made with a much longer wash than the conventional 3 minute rinse, this one soaked for over an hour in the freezer and it wasn't even all that good material (mediocre flower which had already been ground and cold sifted for trichomes) and I used a shitty filter and yet still these nice clear, relatively pale (shows up looking a little darker in the photo than it does in IRL), fully melting, very potent & tasty and nowhere near FECO/RSO dabs result. My freezer is a little colder than average so maybe thats the difference, but I pull substantially larger returns with longer washes and it doesn't seem to impact the quality terribly.
I was once told by an inebriated skunkpharmer that the processes happening during a cold ethanol wash are a function of the temperature, so maybe one day we will have a chart or function that correlates freezer temperature to wash time.
I dub this new tek Long Soak Ethanol AKA LSE (not because it deserves it's own name, but because LSE is a cool name)

nice looking stuff...


and yes LSE, is a cool name (acronym)

Those Chinese units are are refluxing stills.

It also adds a sweet aroma, but both are subtle.



We use 190 proof Everclear or 200 proof reagent grade.

ok, not sure about refluxing, but do I want to reflux
ISO extracts, and/or utilize a technique similar to this in essence a closed loop,
to recover alcohol and control fumes during the process of extraction...?

that sounds very yummy....lol


so in a perfect world, I would want to stretch out as far as possible the use of ethanol
as it is roughly 300% more $$$ then ISO 99,
so a closed loop set up for recovery...do I got that right ?


also, would it be best to do the intial extraction in my ISO 99, lets say
evap off the ISO, then redisolve in the 190 proof ethanol (frozen)...
then evap that in a closed loop recovery set up to recycle the 190 proof ethanol.....do I got that right ?


something similar to this process, will give me a more pure
nice color, and a sweeter tast and smell while burning ?


thanks so much

A simple pot still will only reach around 120 proof on the first pass, so must be run multiple times to purify to 190 proof, which is the azeotropic balance between ethanol and water.


A refluxing still allows you to go directly to 190 proof.

Isopropyl has a lower dielectric constant than Ethanol, so you can remove some waxes from an Iso extraction winterizing with ethanol, but not as profound as winterizing a non polar solvent extraction like butane.

ok cool, thank you GW


so different topic,
how would you set up a home made vacuum assist
in straining off material from extract...


I just do the basic coffee filter routine, sometimes with an added activated charcoal (food grade bone char) rinse...


it takes forever to filter extract...
there has to be a better way, my man
so lets have it...lol


any pictures would be great too...


thanks a lot

I use a Buchner funnel. https://www.youtube.com/watch?v=1JygPCD8bKE


You can speed up the process by using a small paint brush to brush the filter surface during the process, to keep it from blinding.

now that IS a very good tip...

so that works eh...

@Gray Wolf was that BS ever resolved or do you have an NDA from the settlement?
