Sorry if this has been answered...
But has anyone tried fresh frozen qwiso?

I leave everything in the freezer overnight and pour the et on it, wait a few seconds(putting alcohol etc away) and then shake for 20 to 30 seconds, pour through a strainer and then into a coffee filter and back into the freezer to finish draining through the filter. It works great this way but if I do a long wash(put alcohol on and put in freezer for few minutes) with the same filtering the oil comes out dark green.

Ya... its a stripper... we just want to get the trichs separated from the plant matter quickly .. without leaching the booze into the leaves and pulling chloro

I think two bears says he leaves it on there overnight and then somehow seperates the green out with a filter in the freezer

Not knocking his method but thats just extra steps... i like quick. I dont want to turn it into an all day project

here is my last batch shook for 25 sec but took about another 25-30sec to leak thew the filter

ps the cuts are only in the pic so u can get a side by side I did not chop it or cut it in any way it just came out powder ish

How long are your washes? Some people do 6 15 second washed.

I Do one Wash of 85-90 seconds. My yield with the one Wash is 17.2-24.5% yield.

I don't get a massive amount of clorophyll but i do winterize the liquid to filter out the clorophyll fats lipids and solids.

I haven't been extracting for some time, but I previously did liquid butane extractions in a Dewar flask. This was a slower extraction method but yielded a cleaner product. I didn't agitate and washings were about 15 minutes time, with the third being extended to 25.

I should also add to my previous post and be clear that this "3 washings" deal is not a hard and fast rule.

For instance, every extraction procedure at my current job calls for a single extraction, but the criteria are different.

I think three washings is a good rule of thumb (at least two, you expect to get diminishing returns in full effect by the third and it may not be worth the hassle or the solvent) for this product.

If you were to very finely mill the material first to a powder consistency you could very likely get away with one in an industrial setting without feeling too bad about loss of yield.

@GT21 what's your opinion on how much bud can a gallon of ethanol strip?

Would really need to determine this experimentally, and it will vary based on the amount of actives and the amounts of co-solutes.

In any case, for every molecule that enters the solvent, the favorability for the next molecule to do so is reduced. Solubility follows an equilibrium driven regime.

experiment..totally. 1 gallon..1 lb..good starting point

To follow up on that, actually, for a full extraction you generally want to have an excess of solvent around relative to what is needed to remove the compound of interest.

If you're approaching saturation you are reducing efficiency (both time to extract and total yield).

I'd go small scale and do a bunch of runs in tandem.

Extract 20 grams (well ground) with increasing amounts of solvents. 100 mL, 200 mL, 400mL, maybe up to 1L and then evaporate the solvent off and check your yields.

Should give you a good indicator.

ya I get that..half filled jars or so..then after each strip it starts to strip less effectively. I think if it's semi-ground up in a giant jar and strip all at once would be best

Thats why i changed from 1 lb to 1/2... you really want to get good contact on the material
