how do you dry cbd isolate powder without using solvents?

What do you mean dry it without solvent? if there isnt solvent in it, it is by definition “dry”
Do you mean how do wash isolate? is it a yellow isolate and you want it white?

I mean removing the water. Solvents are dry if there isn’t water in them.
I was thinking of mixing CBD in toluene and brine wash then sodium sulfate then evap the toluene.
but really I’d rather have a way in which I don’t have smelly solvents to evaporate.
what I’m doing is putting the CBD between sheets of kitchen paper towels and air frying it at 30c, the fan is very strong but I don’t think it’s enough to really dry it.
How wet is it? I would just throw in vac oven

I don’t know but it only yields 75% pure delta 8 thc and 0% delta 9, with a zeolite tek. although I dry everything else correctly. So my guess is that my CBD is wet, actually it feels a bit wet between my fingers when I rub it.
I don’t have much stuff except a air fryer and jam jars, I don’t have a vac oven
I would make or buy some sort of dessicator. Get a drying agent like magnesium sulfate or sodium sulfate, put it in a large container, and then put your cbd in a smaller container inside.

thank you, I actually have sodium sulfate, is it strong enough to move the water from the CBD powder even if it’s not in direct contact?
Yeah it should work well. Just depends on how much water you’re trying to absorb

0-%d9 that s interesting
Are you running internal analytics or sending it away?
We test a lot of D8 and D9 compliance is intentional, so maybe a second opinion is warranted?

well, I’d rather have 75% d9 and 0% d8, lol
I sent it away, I’m not in north america
One cheap/accessible way to do it is get some silica gel kitty litter. Pretty common in supermarkets, marketed as “crystals” or whatever. The granules are big and often contain moisture indicator, just pick out the painted granules and crush the rest into smaller bits. If you use a coffee grinder, dump them into water after grinding, stir vigorously, wait 20s and pour away anything that’s still suspended in water. Do this a few times to get rid of microscale particles as those can harm you when inhaled and they will take flight just by normal handling and you cant see them. Dry the silica gel at 160C for 2.5h, you can do this over and over to regenerate it.
Then spread out whatever you want to dry on a sheet or plate as large as possible and place into an airtight container with the silica gel. The dryness you achieve depends on how water loaded the silica gel becomes, you can expect <50ppm if total water doesn’t exceed 1% of the silica gel mass which is pretty dry. Do note that silica gel will absorb that 1% just from indoor air in less than half an hour if left exposed. How long your drying takes depends on how well you spread out the product, maybe 24h for a 1mm layer.
If your solvent is dissicant compatible
Mix CBD with solvent and dry out with dissonant
That’s how I dry out dim+cbd over a bed of calciumchloride
Once dry I suck all out undervacuum or by means of pressure ( n2or argon)

do you mean dcm+cbd? Then adding calcium chloride.
But then how do you get rid of the solvent with the vacuum? It all gets collected with a cold trap?
No prior to the reaction ALL reagents need to be dry
Melting /cooking cbd is one way but I prefure to dissolve in the solvent needed with the cbd dissolved then placed on disssicabt to dry
Only caveat DO NOT get dissicant in the reaction vessel
So for salts I place a diptube 2 cm above the solid salt line and either suck out or place pressure on the vessel to get the dry solvent cbd mixture in the reaction vessel
