I do a light fractions pass and I still get distillate that looks like the above picture. Anyone have any tips or tricks to clear it up and or stop it from happening? For information on what I do and end up like this. I ethanol extract, evaporate it down to a ratio ~1:10 or ~1:7. It is then winterized, filtered, and decarbed. Then its distilled at 145C 250mtorr for a light fraction pass. Then on a disitllate pass, I run at 170C and 150 mTorr. I know the temperature is high but I’ve been limited by how low the vaccum pump can go.
Yo i run my temp at 190 to 195 with only 100 microns lowest I can go till my pumps are rebuilt and I had the same issue before and honestly I couldn’t tell you why I don’t have that issue anymore, but I did start to do a warm winterization then a cold one then I would scrub with fuller earths sigma Aldrich, solvent direct sells it as sd boost or ab boost as well then I just make sure that my system is super clean and the flask I use is clean and just run it and bam never have had that issue im sure this doesn’t help but this is my story lol amd some pros are going to get on here and help you out figure the issue more scientifically lol.
I did and while the large amount of answers are that it’s a winterization issue, I also see replies about terpenes, distillation settings, poor filtration and so on.
What kind of rig? Your temps should match your feed rate, nothing else. Thermodynamics and heat transfer, brother.
Also, have you checked this thread?
It’s likely that the streaks and cloudiness are due to impurities (heads/tails) making it into your target fraction.
Might as well tack this on as well since I linked that thread, vacuum levels are not as important as a lot of people think. One can achieve >95% TAC with >250mT.
I tested a bit of raffinate to confirm this. The difference is negligible, i.e. 1% vs 3% difference between 50mT and 250mT. I can usually hit NDs now though.

I did not see that thread. It looks like it has some good information. Thank you!
