steam is pretty magical too. pulls out nasty smelling sterols and fragments of decomposed vitamins.

If by living you mean being a few thousand in debt, and not having food around the house, then yeah I guess you could say that....my teenage daughter is making more money working part time than I am.

It does slow the filtering process but overall it ends up being much less work. Once I have my continuous feed centrifuge, filtration will will be the least of my worries. However, a 6"x48" column makes for a good push-pull filter with the right filtration media for the time being.

What are people doing with the water and citric acid? Has anyone analyzed for % recovery of THC/THCA? Or compared citric to just water?

just rolling through oil refining steps.

i wouldn't put a more polar acidic compound in there and not expect loss.

not like i dumped a ton in there for fun or something.

i don't think the amounts i've ended up with afterwards led me to believe i was murdering cannabanoids, in terms of crude/distillate, i'd say less than with standard multistage winterization.

I saw a dude on IG say "you'll still see waxes everytime you do the process so good luck getting them all"

i chuckled a little.

water washes do great. thats kinda what i was getting at with my last pic. i know my losses are less with just steam, but it's time consuming to boil off water until i don't see anything in the condensate. i hit it with water to chase off terps anyways so there's always a steamer at some point.

pay to play, google or crack a book.

And by crack a book, I assume you are referring to Bleaching and Purifying Fats and Oils by Gary List, but please correct me if I am incorrect.

I appreciate your posting and having been using a similar method. This seems to be a reasonably simple purification step when used prior to or in combination with winterization. The downside is that the water reduces the proof of your alcohol making solvent recycle less effective.

Before discovering the acid-degumming process I have found strange gunk or gum in my rotovap and short path after performing a scrub with acid-activated carbon. The gunk was thick and black but could be washed to what I assume to be an insoluble grey gum. Interesting stuff! With the possibility of using washed waxes from winterization for lotions, soaps, and candles, what kind of uses could be found for separated cannabis gums?

it's used in nonstick sprays and as "anti-sludge" in fuel/oil treatments.

Yes, @ColumboLabs and @Future4200 on Instagram are documenting their trials with oil processing with a caveat that people remember we are processing resin, and not vegetable oil and that accommodations have to be made for that difference.

yes. res.....oleoresin and even more correctly still.... gummoleoresins.

far few nhp than some food oils, but more than some.

all of the "food oil" qualities desired are the same,

shelf stable (wont oxidize and change color/polymerize on ya),
no stank (deodorized with steam),
transparency(improved with shit removed)

and all of the contaminants are the same or similar and are removed with the same or similar processes.

if everyone abided the food oil refining steps.....well we'd all have good medicine! distillate wouldn't change colors. oh the smoothness.

Agreed, but then people couldn't pass off less refined products as "less potent" and convince people that "numbers don't matter because it's a shell game". Personally, I'm trying to promote clean, widely available and consumer friendly, which implies cheap so processing has to be efficient. I'm applying these methods to Supercritical CO2 oil that has been diverted from the process stream as "waste" so I can better understand the impact it's having. My products currently enter product formulation as a 98-99% cannabinoid by volume distilled oil typically high 80% delta-9 with some small percentage of CBD, CBG and CBC. I like being able to give the consumer a clear idea of what they're consuming and some sort of informed expectation. I don't want them to have to wonder what the other 30% of the mass they're consuming is. -_-
