I’d like to eventually convert my extractor to run ethanol instead of butane.
I could use nitrogen to push cryo ethanol through my material columns. Then I can use nitrogen to attempt to dry my columns. Then, I can vac my columns to dry even further with my diaphragm pump. Lastly, I can inject steam from bottom of columns to completely dry the columns of ethanol.
Any thoughts?
Edit: Are there any specific types of gaskets needed?
(Sorry if this has been posted somewhere I didn’t find anything)
It could work, make sure all your seals are compatable. Upgrade your recovery side with the 1" or better tube, ditch the fiterdryer instead use this.

Place it in the solvent tank fill it with mol seives . I wouldent inject any steam, better to pass it through then column jacket to bake it dry.
you may want to add a condenser as well .
Same way you do in a rotovap at 80f, by pulling a vacuum.
Recovery tank? Yeah, I probably plumbed it back to my recovery tank, the object of the game was to make the boss think I was using butane. We were not licensed to. So I didn’t
Could have dropped it straight into an ever clear bottle. But that’s cause I had the condenser in the wrong spot
go check out BizzyBee’s ethanol gear. It’s essentially identical to his hydrocarbon gear. he’s even back-ported his falling film to his hydrocarbon rigs.
I dont think you will be able to recover your solvent the way u want to. I wouldnt waste time with leaving the material In the column and trying to recover the alcohol that way. A Centrifuge will be your buddy. You will be leaving alot of cannabinoids on the leaf matter if u recovered ur solvent from soaking leaves, or u would be wasting a bunch of alcohol rinsing your material if u still wanted to go that route without leaving much behind.
It takes me 5 minutes to unload the column and pack it again with a sock and a 30 minute soak time. It takes me 10 minutes with 2 pandas to get 95-97% of my solvent back from the 6lb trim column. I think youd be spending much more time then 10 minutes trying to pull vac and heating ur column.
If ur trying to keep it cold as u can, it makes no sense to pull vac on ur column and heat it, to get the last bit of alcohol out.
FYI I use 100 micron filter socks and 1" piping. 1/2" could clog if a Nug fell out of the sock, havent had any issues with my 1" drain port.
