Hey guy’s need some input and advice, i am currently processing cbd distillate (80-95%) into isolate. Using the glg /future tek.
Using 2:1 as well as 3:1 pentane to distillate melting on hotplate with temp probe and stir bar to both 32c fully dissolved as well as 37c fully dissolved.
After a few days I get heavy crystalization .
Here is the issue when i scrape the beaker side walls i have clean crystals I can wash chilled pentane about -20 freezer dosnt go that low and our other is -79c too cold . crush into a pure white powder (90-99%) through lab tests trying to hit a min of 95%
Nnow the bottom is always a giant chunk but rinsing the same way dose not come out as clean. So I have been crushing those chunks and attempting to wash in pentane to remove impurities and color.
Only issue with that is I end up loosing some isolate or the color just dose not want to wash away with out multiple washes .
I have considered recrystalizing but due to time space and loosing more cbd to mothers milk/liquor it seems to be a bit of a wastefull process
Pour off your mother liquor, chase remaining shards out of container. Wash them with cold pentane. Then take it and crush it back up and deissolve and re crash. Your original crash wasn’t fully cleaned up prior - this is why some people wash the mix first to remove as much milk as possible in some cases. Anyways the point is. Recrash and each time your potency will climb. Then wash, crush and dry and boom.
Get a filter reactor, it has a removable bottom plate that is design for crystallization.
They are UL listed to C1D2 standard and they have a condenser for your pentane vapor, so you can recycle most of your solvent as well.
Thanks! This instagram post was from one of my friend in CO. They are getting 2 more 20L filter reactor in house.
Let me know if you want one in hands.
