thanks for the information and correct terminology.
Chances are you’re also using too much solvent.
How much biomass are you running through that 30gal of ethanol.
My math suggests you’re at about a kg/gal. You can get away with lb/liter at -20C
The links above might well get you where you need to be.
There is also a “buy a clue” option available…
thanks,
42 lbs of biomass through 30 gal of ethanal.
So less than a kg/gal…
Washed thusly: It washes the cannabis and then it washes the cannabis some more you can get more cannabinoids with less solvent.
If you read through all the threads linked above and would still like help putting the pieces together, hit me up via DM.
50lb with 15 gal ethanol. At -40C. Without a decent pump.
Halving the solvent used would help no?!?
how many times do you wash your biomass?
Have you not followed any of the links?
Wash and a rinse…
Have you calculated your extraction efficiency?
The rig pictured above was getting about 85% of available cannabinoids with ~12% TAC feedstock.
With the correct tooling you can manage considerably better
yes, I’ve reviewed the links provided. No, Have not calculated the extraction efficiency and not sure how htis is done.
42lb in 6lb out.
Brain dead “yield” is ~14%
Use potency on both input and output to see what you’re actually achieving… perform Mass Balance on your cannabinoids.
10kg biomass at 10% thc => 1kg of thc in your input.
1kg crude at 75% thc => 1000 x 0.75 = 750g in your output.
What was the efficiency of your cannabinoid recovery, expressed as a percent?
I suggest always using kg/g/mg for you cannabinoids, but given the way units cancel here, it doesn’t actually matter, so long as you use the SAME units for input and output.
Input mass x input potency
————————————— x 100
Output mass x output potency
Edit: and for continuity:
Follow the cannabinoids not the cadabinoids
Can you describe the difference between your wash process and the wash @Lincoln20XX documents for us?
WHY does it require less solvent?
Each 20 liter roto should be recovering 5 gallons an hr at proper temp and vacuum
I’m pretty close to that for about 4 hours of running, it tends to slow down as I start getting more crude oil collected in the fask. Thank you
notice anything you think might be worth implementing over in Optimizing your RotoVap ?
Things like prewarming your input, spraying into the evaporator? Emptying the evaporator without removing the flask?
Are your chillers slowing you down?
What could you do about that?
Don’t you think it’s totally flawed that no one calculates percent yield (correctly)??
Mass yields are very misleading imo
I know it’s extraction but I think everyone would benefit from uniform terminology
Nope, I reckon y’all should just follow the cadabinoids bro…
That is what I’m saying
