Yeah I’m kind of addicted to the forum lol. Everytime I see a new notification it’s a little shot of dopamine.
I’m kind of intruiged with what might be possible with the supersaturated etoh solution this way. What kind of extracts it might be suitable for.
What’s your thought for rinsing your biomass, or if there’s any issue with residual cannabanoids the more washes that go on?
So I’ve started using a separate vessel next to the main extraction vessel to do a last soak in after the first panda wash. My op goes:
Dunk bags in etho for 10 minutes.
Drain and put in panda for 5 min.
Take out and soak in second vessel 2 min.
Spin 5 minutes in panda.
It helps with several pandas to keep it going. The damn spout is so fragile it breaks on the slightest contact, but a forum member is working on a solid fix for that, I’m told.
I managed to rewash 45lbs at least though 5 gal. I definitely feel i got something out of it. But I’m actually, once i get material, going to separately roto the rewash to figure out how much it yields.
Edit:(cause I’m high)
Until i can do a full 50lbs/5 gal extraction with the rewash, I won’t wholly know how much really is saturation. I’m relying on ecodyst to have the correct information, I will try and confirm the data.
I also would like to do a true side by side cryo and room temp on this, tbh.
Reedit: well damnit. It looks like things are really good for you. Why in the name of the fuck are we trying to get them out again? Am i reading this wrong? This sounds like they should be beneficial?
"During the last years, an increasing interest to anthocyanins, as natural colorants in food industry and anti-oxidants in medicine is observed. These compounds have positive effects on different diseases, including cardiovascular, ophthalmic, inflammatory, and neurological ones, as well as cancer and diabetes "
So I took last night as a small experiment some very dark oil from old material, about 30 g of it. I threw it in some heptane and I should mention I had earlier prepared a Buchner with T5 on the bottom then layer of food grade carbon then silica 60 and another T5 later. I’m sorry to say that there was only limited color improvement, not brown black now but it’s all brown and dark still. Not really with showing… I’m amazed at others colors here. I do however note that the lost biologist uses 200 proof as does the Instagram account posted above. I use 190 and I am stuck in the Reds and oranges usually. This material is not intended for distillation. I’m considering trying Magnesol next & technical rather than food grade carbon
Also does anyone else get brown terpenes out? They’re dark so I worry about them contaminating color. Whenever I re distill my alcohol for reuse I end up with a bunch.
You say you made a t5 filter bed but put carbon on top?
What kind of carbon are tou using granules or powder?
Would have been more effective if you mixed the carbon with the heptane solution and mixed the shit out of it. The t5 filter bed would have caught any carbon particles and it would allow the carbon some longer residence time. You may as well also add some t5 to that solution just for good measure and then just pour that over your t5 filter bed.
I stopped using heptane because it turned things red/ orange. Maybe try and take that out of the equation once to see if there is a difference?
I think someone said acivated alumina catches reds
My carbon is simple active charcoal from coconuts, a food supplement brand. Here is the yellow ethanol solution from above dried down, this one did not get heptane. Note two shades of color, the lighter one went through a carbon and t5 filtration. both color suck! I usually skip heptane just want to see if I could improve some real ugly stuff @Renchi
I saw that acabout activated alumina but it didn’t seem to be a ingredient in the CRC tech. There’s a lot of choices of powders and qualities this could get really expensive real fast
Have you considered the acidity of the carbon you’re using may be causing the extract to darken? Do you neutralize the ph of the carbon before you use it? Or does it come activated but ph neutral?
i
I do but I’m not putting any heat in the system. I I try to be sparing with it and I have gotten some decent lighter orange extract’s while using it. If I decarb I get super dark red though. It does a great job on greens if I get any of those
Regarding the activated alumina, it’s interesting to note renchis results above with only Magnesol T5 and carbon. I thought that he’s getting really close to everything including all carotenoids so I was considering picking up some Magnesol and neutral carbon for that reason. But I noticed the AA seems cheap so I could add that to
When you guys say bentonite, that’s bentonite clay? Longer soaks if that in cold ethanol wash is best?
I’m on the same path as you renchi, to figure out how many soaks are possible in room temperature ethanol but still making nice cartridges like you ended up with, nice job.
Thanks, brother. Yeah, it’s the never ending quest. Lol. Tbh, i feel like the room temp saturation soak is the way to go. But until i can do side by side comparison, I’m still guessing. Hopefully it aligns itself up
Use hardwood based charcoal! Coal & coconut & bamboo aren’t very effective for color pulling (ran experiments with all 4 types). Charcoal is pretty much only good for greens tho!
Sorry about the double posting. Just been way out of it lately.
I have all my extract suspended in methanol now 6:1, and it’s still very black after washing over alumina (on top of a generous B80 clay layer and celite). I was told this crude was run through a wiped film once and it was ethanol extracted, though I wasn’t told if it was cold etoh or room temp. By the looks of it, it almost looks like a hot ethanol wash. Surprisingly I pulled a ton of green with the fats. It seems the B80 pulled some green as well. I was thinking of running it through carbon while in methanol, but I’d really like to see how it comes out after evaporating the methanol, dissolving in heptane 4:1, and running through a CRC column under positive pressure. Here’s pics of what I pulled with the methanol dewax below. The green layer felt VERY greasy between my fingers, so I’m pretty sure it was waxed and fats that I pulled.
Looks like a solid cleanup so far!
