I am wondering if any of you have any clever scheme's for getting the most out of an A/B extraction.
I am doing veg oil extractions and I usually end up with about 10-15 good doses oral doses from 100g of plant matter (confusa or mimosa). I can't really measure my yields because I end up with acetate and have not been able to convert to a measurable freebase powder (it usually becomes goo after basing and extracting with acetone or naptha).
So I estimate my yields at probably around 1%, which is not bad but it would be great to reach a consistent 1.5 or even 2%. (I'm a bit jealous of others getting 2% from ATB and STB methods). ATB and STB don't work so well with veg oil because the plant matter absorbs so much of the oil, and increases the volume of the mixture considerably.
I think the limiting factor must be the acid phase. I usually use a decanting method rather than the standard 3x boils, since in theory you shouldn't need to boil powdered material. Boiling seems to create a very cloudy solution which takes much longer to settle. I usually boil the mix at the end of the decanting just to make sure i get everything out, but by then the water that comes out is murky but lacking the dark color of the initial decanting. Anyway, so boiling up acid water and then mixing that with the powdered plant matter and sucking off the supernatant with a baster once it has settled. I am using vinegar as the acid, usually starting with 250ml and then adding a dash with each subsequent wash.
In my next extraction i will try doing the standard 3x boil with some decanting after, using vinegar and also citric acid to maintain the acidity during the boil.
Any other ideas? Would the freeze-thaw idea but a good thing to try for improving the efficiency?
