Hey guys ! I’ve been purchasing CO2 extracted terpenes from a vendor and have been experiencing some cloudy product. We been working with this particular vendor for about 5 months now with no issues. Any way we can remediate the terpenes in house instead of sending them back to the lab. A friend mentioned a micron sift. Any suggestions would be appreciated!!!
Have you tried freezing and filtering it? Like a pseudowinterization of sorts.
I’ve dissolved a jar of rosin in 99% d-Limonene in place of ethanol, froze it, filtered, and removed the Limonene (takes an eternity btw) and it was transparent afterwards. I did not test the composition of the impurities afterwards so I couldn’t tell you how much I lost for cannabinoids but it definitely removed a great deal of lipids/waxes. I do not know if it would work the same with a full spectrum of terpenes but it seems like the least invasive thing to do. I prefer to keep cannabis terpenes in the freezer anyway.
I’ve sent back 2 kilos for post processing and recommended a freeze and filtration method. They’ve started today and hope to get some results back. Could the C02 density be to high? Maybe crank back 20 - 50 PSI per run while increasing temp by 1F. Appreciate the response.
Did you get an analysis residuals because your pic looks like a lot of thca got fractioned with the terps
I sent out a sample for analysis a few days ago and I am expecting CoA’s by tomorrow. I have a few formulations made in carts and after a few days the components set right on top of the atomizer. Makes me lean towards THCa.
CoA’s came back. 27% Thca with a total cannabinoid content of 33%.
Definitely THCa! Large percentage in mixture.
Looks like we have had some minor success in letting the solution sit at room temp. for about 2 weeks. This allows the THCa to separate giving us an ample amount of usable fractions. Check out the photo!
Using wet biomass would create a massive issue in the system. We run 5-12% moisture content.
What’s your opinion on the separation at room temp?
We plan on using a short path at a high vac and no heat for remediation to speed up the process.
I’ll be interested to hear how that goes
Co2 sauce, wow that’s pretty cool
Rather dark in concentration. I like tipping the jars In order to see the hue along the walls. These were achieved through natural separation over a period of a few months at 60-65F.
Maybe try spinning it down in a centrifuge? Just get one of those table top centrifuges that can spin 25-150ML test tubes. Any standard centrifuge for those sizes would probably work well. Just make sure to counterbalance your loads before spinning!
Appreciate the input! Waiting to see on short path remediation results. This would be a great alternative.
