official extraction help thread

Migrated topic.
Generic 5% white vinegar that I bought a few days ago. If its just plant impurities then it shouldn't really be an issue right? Other than maybe making the vapor a little rougher. Also should i be leaving the solvent in the lime-bark mix while i wait for the next solvent pull?

Got a question on upping yields

I recently observed an extraction of 100g shredded acacia acuminata root bark
5 vinegar acid cooks "PH around 3" were reduced to 600ml then added to a 1L bottle
30G salt was dissolved in 100ml water and added
60G Na0H was dissolved in 200ml water and added to a PH >12
bottle was put into a slow cooker half full of water on low to keep it all warm
5x 60ml shellite pulls done over an hour each flipping or rolling every 15 minutes but never shaken
2x 50ml xylene pulls were then done cold out of the water bath but otherwise the same method.

Shellite pulls were evaporated over a fan until about half was gone, and it looked milky. Then, it was put into the freezer. 36 hours later, it was removed & there were 360mg of pure white crystals after evaporation.
Xylene pulls were put into a food dehydrator for a few hours @70c until a goldish oil remained that smelt of new shoes, this was removed and agitated while cooling with the tip of a razor, and the oil soon "15 minutes or so" transitioned from a liquid to an orangish powder "dmt+nmt"? weighing 170mg

total yield was 0.53% not bad for the first time but less than expected.

Current thoughts are to do the same thing but use a pressure cooker @12psi for the 5 acid cooks & blend the bark as much as possible "Last time 0 processing was involved"
any other tips would be greatly appreciated.

I've heard somewhere that some root bark sellers will remove fibers from the bark then sell the "shredded" stuff as mostly just fiber, giving it a lower yield. This is just speculation though.
 
That does kinda check out or more appeals to my self-confirmation bias that it's not me lol...
2'nd extraction is underway with 3 changes decided on

1. 3 Freeze/thaw cycles before starting
2. Powder/grind as much as possible
3. Pressure cooks instead of normal boils

While attempting to powder the bark it was noticed that very little was happening, Blender, coffee grinder then immersion blender was tried without much success at all.
It just seemed like for lack of a better word "coconut husk".

Onto the 5th cook now so I'll report back if anything changes.

Yea, it really shouldn't look like just coconut fibers, you should getting whole bark chips or cut up pieces of bark. The fibers alone can't really be "powdered" easily like the bark itself can, which makes it even more difficult. I recommend finding a more honest seller if you can, they are still out there, or buy powder from them if you can't. I hope you'll be able to still get some yield out of it.
