I am wondering if it is possible to use a large short path evaporator to recovery solvent and concentrate our oil all at once instead of a standard thin film evap and then going to a short path. I am looking at the larger industrial types and not the glass table tops. Something in the range of 10-30 sqft. We are still working on our output volumes from extraction. We will though have a already concentrated oil ethanol mix from our extraction along the lines of what you would have if you did 3 cold washes with the same ethanol.
You need a consult. Not being rude, just trying to help.

Oh boy… well all the info is in the forum
Don’t people use FFE for large evap and concentration
Yes you can use the spd-7 that way. There’s a post about it a couple days ago I posted.
I guess it would clean itself before the run!
Thin film is used to separate the cannabinoid fractions. Falling film is a high output solvent recovery. Short path distillation is also used to separate the cannabinoid fractions. You can use a SPD head as a “pot still” without any reflux to pull your solvent from your tincture but it’s not very efficient.
The problem we have found with falling film is clean up. Yes everything needs a clean process but I have heard falling is worse. The larger short path use the same thin film and have a vapor outlet as well as the residual and distillate. So the benchtops I get they don’t work but on the larger units is there a possible use.
Question is has anyone used an industrial size before and what did it do?
I’d rather see you buy @spdking 's summit spd 7 with a peristaltic dosing feed pump and a stainless steel heat exchanger skid teed off to a diaphragm pump then switch over to normal spd procedure.
