Dewaxed Co2 Oil Without Winterization?

[gt pureweed]

Ah OK, so a little frozen CO2 in the yield is typical? Thanks for your insight, we're getting results similar to your picture, so I guess we're on the right track, I just wasn't expecting it because I hadn't seen anything like that prior and was alarmed to see a frozen solid block like that. Given the amount its mass dropped when we let it thaw, I was worried we were trapping and losing too much CO2.

What's the best way to get all that residual water vapor out of that? We've been using a vac oven, but it's been taking a lot longer than we'd hoped. Any alternatives? Rotovap?

Vac oven, Rotovap. or just warm it up in the oven without vac, then suck them out with a syringe with dispensing needle also works. The water should separate after some time once warm making it easier to deal with. You could also leave out @ room temp and after many days the water would evap off...but not very productive.

Awesome, thanks for the help, I really appreciate it.

Have you ever run fresh frozen through a CO2 extractor? I want to try it out since it should preserve more cannabinoids and terpenes but am worried the excess water will cause issues.

Freeze dry or bake to get the water out is the recommendation from Apeks. Bake if you if are making a decarb oil. Freeze dry if you are not.

With the right settings and some adjustments depending on the Separator numbers... but one can get the waxes in one chamber and the dewaxed (terpene rich oils) in the secondary separator. Gotta run cold, but not too cold other you make dry ice and will make an
@pureweed. I'm new here and new to co2, can you elaborate on what are the different psi's for the seperators? It seems all i pull out of my second seperator is water.

@califarmer5

Your extractor psi and temp is where you can control running subcritical or supercrital (sub meaning below and super meaning above, and in case its referring to one of the critical points for CO2 @ ~ 1088psi +88F). All systems are different and have minimum and maximum settings, so always consult the manual first. Subcritical gets lower yields but has less waxes/fats, supercritical gets higher yields but with more waxes/fats. The separation settings will vary based on the system. For Apeks they recommend trying to achieve around 250-350psi in your separator, whereas others may run @500psi, Generally it will be below (or you want it to be) 600psi as this allows for oil separation from the CO2 as it returns to a gas state. Which ever system you are on, this can generally only be adjusted by changing out the orifice and running a few runs and recording your data. Again consult the manual for the system in use.

Hey. Thanks for the quick reply.. I will try running lower psi in the separator and extractor and see what happens so far I cant say i have tried subcritical. So running sub and running seperator 1 @ 1000 for wax and seperator 2 below 250 will most likely give me two fractions? Otherwise seems you do great work thanks for the advice. As i progress i will post.

And does your water have more of milky look to it or an odor to it? If so its more than just water...those are hydrosols.

 

[califarmer5]

Yes i have been collecting them.. Whats the difference of terps vs hydrosols? Sorry im not a pro yet.

 

[gt pureweed]

Those hydrosols contain terps..usually high in pinene (which you would be able to taste and smell). That's a nice blend of water and terps, great for medicinal creams.

 

[califarmer5]

Cool man i figured, sometimes when i drop seperator 2 down i see some oils in the hydrosols too. Because i have two separators and not three, it would be harder for me i figure to pull waxes in one and oil in the other maybe not.. Its just a bunch of running it to learn lol.

 

[gt pureweed]

Yea, each machine is different. Record data every 15-30 minutes that's what taught us the most I'd say. Then try to control your different variables even down to the trim or material level. Isolate a single one and methodically make changes and record the results. 3 months of good data can lead to huge breakthroughs.

@gtpureweed
Thanks for the tips. Im going to do that. Keep my handy notebook. One more question if I may. Let me clarify you fractionate waxes on sep1 above 600 and sep2 oils below or at 250?
All while running in sub?

 

[gt pureweed]

I'm not able to really change to psi between the two separators, both are around 250-350psi...that's where each system is different, but yea try running subcritical in your extractor. Both of our systems have an extractor tube..then 2 separator tubes. Both Separator tubes run the same settings for our system.

The only thing you need to be careful about is oil carryover. When doing this, its a big risk to getting oil back into the gas booster or whatever pump system.

@gtpureweed. thanks for the tips once again.
I dont think my system runs subcritical.. I was running at 1k psi in extractor at 31c, and sep1 @ 400psi at 30c and sep2 @400psi at 26.c its hard to get lower seperator pressure cause under 5oopsi the seperators pressure stays unless i purge them manually when i start recovery. All i seemed to pull was ice, it was a true bummer, as i don't have interchangeability in my orifice i don't believe. I will just have to get my post processing skills down and work from there.

Interesting. I do not think the separation can be done at low pressure. To everybody else in the thread..It is interesting to see the partial fractionation, but it seems like you all have a major leap to produce the clear amber lol I could give you the secret, but it wouldn't be fair ^.^ not to mention non competes and such.

 

[gt pureweed]

some of this?

some of this?

Is this a subcritical extraction? Looks like the right stuff to me, but not the blood red I was getting. That aspect might depend on the weed itself and the extraction conditions but your separation is perfect! I did get purple oil from purps. It was soo nice. Also, did you vac off all the terps? Sad face :( Can you get this?

 

[gt pureweed]

Subcritical...oil in one separator...dry wax/crumble in the other. But it's gonna depend on the CO2 system, not all systems are designed the same.

Looking good, but still no amber. Where is this oil coming out of?? Cali?
