CO2 Derived Hemp Terpenes

BDT makes me sad…

I wonder if really high grade hemp or certain strains don’t have the grassy notes mentioned.

Whoa buddy. You better be careful with them. I wouldn’t just run them without very tight persmeters. And the right equipment.

Not exactly sure what you are saying. I wasn’t suggesting to run terps through a short path, I was bringing up the question of if that would degrade the terpenes or not.

I prefer to use selective parameters to pull transparent gold fractions that do no require filtration, water removal or other post processing.

That’s the advantage of CO2 being a tunable solvent. Seems like people forget that and try to do a bunch of post processing work instead of designing a more efficient extraction method.

Any input to share on parameters temps to achieve this? We get close but always have water/hydro come through in the fraction.

Fixed the post to make it answer its self

Low pressure, low density, supercritical phase. I have achieved no hydrosols on an Eden and more easily a Thar.

Are you suggesting every time you change strains you have to change your extraction parameters? Because this was not my experience. With tight control of parameters, I would get consistent results like pictured below.

When the input material is exceptionally dry and grinds into a finer particle size, I may get a smaller cloudy fraction. Depending how much, I just toss it into the transparent fraction and it dissolves well.

In my unprofessional opinion, this is an example of terpenes done right.

And this would be parameters that were not selective enough resulting in larger fractions of contamination. If your terps look like this, you may need to adjust your parameters or stop extracting boof with little to no terps to begin with.

Ever run an apeks? I think our issue stems from the separator temp not having independent control from material column.

I have never run an Apeks but that is a flaw in the design in my opinion. What pressure and temp is your separator? To get more selective terpenes 110F is a good general number, you can go lower if you are worried about more delicate terps.

Those last two fractions can be filtered with a centrifuge filter

So your terpene extraction parameters do not extract any water from the biomass?

Could you run fresh frozen and still get those clean fractions?

Correct. I have a video on my IG @Tpurp7 showing a terp collection.

I have never run fresh frozen but was really interested in hooking up a chiller to my extraction column and trying.

I think I can make sauces like the bho and solventless bois but never got the chance to go full send on my crazy experiments.

What state are you in? I’m a class c processor in Michigan with awesome co2 terps

Need that

My whole point was to use more selective parameters to get a high quality product right out the machine and avoid the production time and product loss required to refine them.

I do suspect even with really selective parameters you still got a few of the heavier terps “locked” in the lipid fraction. But in my opinion, unless you are making an unwinterized CO2 HTE, those terps may be goners.

Not saying my way is the only way, I just found it to be the most beneficial model for me so far, in terms of efficiency and product quality. Especially, when you are limited to cheap centrifuges that do not even work or no centrifuge at all.

If you have a larger cloudy fraction that isn’t too fatty, you can syringe filter it. I typically had such a small fraction of cloudiness that I would mix it in with the larger transparent fraction and you couldn’t even notice.

If you got pics and data on heavy lipid terp fractions being cleaned up I would love to check it out. I have never used a refrigerated centrifuge, so I do not personally know if it is worth the time and effort to recover those remaining lipid locked terps or how well it would do so.

This is frankincense terpenes extracted at 20f@ 500psi. The terpenes out of the separator had a murk to them that settles out as a golden resin with 48 hrs in the freezer.

I have cleaned up alot of cannabis terps this way but it definitely takes alot longer.

Do you think having a jacketed extraction column is critical for clean LowD supercritical terp runs?

It’s nearly impossible for me not to see a 10-20f delta on the inlet to outlet of my unjacketed extraction vessels.

Filling the vessel for a LowD terp run is difficult also, keeping the inlet temperatures high enough not to expose the biomass to liquid Co2 is a slow process.

All the machines I have run had jacketed vessels on everything; extraction vessel, separators and accumulator/recycler and I can’t imagine running a machine without jacketed vessels.

If I remember correctly, my inlet temp was slightly warmer than my outlet temp but I focused mainly on my outlet temp for extraction purposes. If I saw outlet temp was too high, I would adjust.

On the Eden, all the vessels were jacketed. I would preheat my machine ahead of time and have the separators and accumulator already filled and ready to go with CO2. My extraction vessel I would pack with cannabis right before I was ready to run and start the machine right after. This is because I did not want my cannabis baking in the vessel before extraction. I would close my extraction vessel and use the CO2 already present in the loaded machine instead of from a fresh cylinder to run my extraction. If I remember correctly my E.V temps would drop once it was under a load of CO2 so I would set them slightly higher to compensate for this.

On dual extraction vessel machines, you can have one vessel empty and “prime” your machine with the empty vessel and switch over to the cannabis once the vessels are up to temp and the pump has had a chance to “warm up”.

What density are you looking at? I run a thar and have found density around 0.33 g/cm3 to work well, but have struggled.to constantly maintain that throughout a whole run. I still need to filter once on most of the collections

What did you use the frankincense terps for? That would be interesting combined into a 1:1:1 thc:cbd:cbg tincture with cannabis terps also in it

Also what kind of yield did you get?

We sale them on our website and also use them for formulations. Frankincense terpenes are excellent for your skin when diluted with a carrier oil.

I have personally formulated vape products with the frankincense and I can attest to the fact that it has a strong mood lifting effect.

The vape I formulate with the frankincense was mainly used as a experiment to see how long I could avoid getting the last round of covid. I would take one pull of the cap every morning after brushing my teeth while basically everyone around me had covid. Long story short I never got sick and I started to use it to help those that were sick get to feeling better.

The yield can vary wildly depending on the quality of the frankincense. I buy the best frankincense I can find and can pull 5% pulls from it.
