Improving Extraction Efficiency

[cyclopath]

You say you’re looking at cannabinoid recovery, then give raw yield…?!?

Edit: see you posted efficiencies while I was as typing …

30% of available cannabinoids…yeah, you need to do better.

Top or bottom fill?

I’m saying when we test our spent biomass we usually leave behind 2-4% thc. This varies with material consistency, incoming potency and strain dependent too.

You need to keep in mind pretty much every system on the market does the same overall process, it fills the material column with solvent and then it soaks for x amount of time, sometimes no soak at all and then it drains. There isnt anything novel about this step and your efficiency will not differ from any other system unless you do something different. like re-circulation or agitation. Luna does do one thing that’s somewhat novel and that is a pressure soak, after its done filling it will take the vapor from your collection and build pressure in your material column. This is an option you can set in your recipe, and we have found it does help keep the yields more consistent and slightly improved vs a static soak. it also speeds up the drain time and cuts the overall run time down.

Try extending your soak times. Try a third wash. Ideally you would use mass balance on your cannabinoids, but you can also get a reasonable approximation on “is this helping?” by recovering that third soak separately (makes exploring the search space cheaper if you don’t have in house analytics).
