Hello F24K Friends,
Were in the process of bringing an Ethanol Extractor online, and I have some Questions and Concerns…
I was told the coldest our ethanol would be is -20 C on the first pass, and subsequent passes would be as “warm” as 0 C max. The unit requires a minimum of 30 Lbs of biomass and 30 gallons of solvent to run. Yes, there we have an industrial chiller. No, I don’t know why this Fiat sized machine can’t do better.
The idea is to be sure we pull all the desirable compounds along with the crap, to ensure a near 100% extraction of cannibinoids. In theory, this is great, but subjects my coworkers and I to some extensive winterization, filtration, and color remediation.
So, here are my questions/ concerns…
Where to put the carbon scrubber? I’ve read on the forums here some people do it pre winterization and some do it post. Is there a clear advantage to one or the other? More specifically, does it have to do with the initial quality of crude solution? IE, is easier to implement this strategy when starting with a more pure solution? and will I slow or clog the flow by attempting to scrub such a low grade crude oil prior to winterization?
What is the best way to stage the filtration to mitigate needing to change them as often? I should have access to 2 or 3 high pressure SS filtration vessels and can stage them either inline (which is the current set up, Large pore size to small) or in parallel depending on what should be most efficient. Here are my questions… For EHO post processing winterization what is the lowest micron you would suggest? I notice the 10 mic catches the majority of the fats and waxes. Is 100 too high? I believe the options are 100, 50, 25, 10, etc. With 3 vessels I was thinking of staging them in descending pore size, but hoping to catch more before the 10. The staging will obviously be predicated on what is deemed to be the correct/ appropriate sized final filter.
I really appreciate any advice, opinions, and or feedback!
