trivial math…
10kg of biomass at 10% CBD =1kg of actual cannabidiol.
lets assume 85% extraction efficiency in that CUP, and a potency of 75% CBD on your crude.
…now your 10kg yields 0.85kg of actual CBD.
as the CBD is only at 75% you actually get 1.13kg of crude.
if that’s what you’re calling “CBD oil”, you’re done. understand that if you’ve used “hemp” at 10% CBD, your crude is now at 3-4% THC and is non-compliant.
Sorry, I should’ve used the term “CBD distillate.” I was in a rush and typing from my phone and didn’t realize how that could be an issue. Doh!
do you really think you’re the first one to need an answer to that question?
or the first to ask it on this forum?
it’s been answered.
more than once.
eg: Hemp Crude-Distillate Yields
or theoretical distillate yield?
and yeah, if you mean distillate, calling it “oil” doesn’t do anyone any favors.
have you figured out how you’re making “compliant” distillate yet?
because distillation is not going to get you there.
I use the search bar before asking any of my questions. I’ve pretty much been conditioned to do that spending so much time here.
I couldn’t find what I was looking for, but I’ll try again.
Yes, calling it “oil” over “distillate” was 100% my fault.
what exactly did you search for?
was it that “CBD oil” that messed you up?
Search results for 'distillate yield' - Future4200 seems to work well.
Were getting approx 800 grams of T free distillate from 15kg of biomass testing at about 12-15%
We do still have a little bit of fine tuning to do as our thc fractions have a little bit of cbd and cbc in them.
Hahaha, you’re cheeky 
I eventually realized I should use the word “yield.” Let this thread die now!
Thank you as always Mr. @Cyclopath.
No worries. Asking the correct question when you don’t know what you’re looking for is a non-trivial task.
While I can no longer claim to have read even 1/2 of what has been posted here, nor claim to remember even 1/2 of that, knowing the answer is here makes finding it easier, and cross linking related threads helps all of us.
Are you using chromotography equipment to fraction out the THC in the distillate? Or what method are you using?
Yes, were using a very manual form of chromatography, self packed 14L columns and collecting fractions manually and testing those fractions with our hplc.

Nvm. Saw your answer above.
Chromatography
You cheeky bloke you… 
I do CO2 extraction and process 13lbs a hit and harvest approximately 300 -350g in 2-2.5hrs.
Input and output potencies?
Follow the mass balance, or you don’t have any clue how much you’re leaving behind.
What do you mean by mass balance?
I get about 3.4g per pound per pecent
10kg of 10% CBD contains 1000g of actual CBD.
where is it when you’re done?!?
How efficient was it?
eg 454g of 10% biomass should contain 45.4g of CBD.
if you’re getting 34g of 100% CBD you’re at 34/45.4 => about 75% efficiency, and are leaving 25% of your target behind.
if however, that 34g of “CDB” is actually at 60% CBD (which is my guess at unwinterized CO2 crude), then you’ve only got 20.4gram of CBD and you’re looking at less than 50% extraction efficiency.
Would you be willing to share any thoughts on increasing efficiency? Thanks for the explanation as well!
change solvents: Ethanol v. CO2 v. Hydrocarbon.....Cage match 420
or add a co-solvent. Open source CXE retrofit for Co2 extractors
after first grabbing the terpenes. Refining Hemp Terpenes
which CO2 is apparently pretty good at.
head back over to CO2 extraction in an Apeks machine. and tell us more about what you’re currently doing.
