That’ll do it
So I’d recommend valves to throttle your feed input and your vacuum levels; as well as your evaporator temperature.
It’s going to be a balancing act between those three variables to your evap rate. Probably take a few hours of fine tuning to decide how you want to run it.
It’s probably your cheapest evaporation per $ outside of scavenged heat exchangers. I think you could get 30lph of condensing before you run out of surface area

Is there anyway to reproof as you’re distilling? Like is it possible to always have a 190 proof ethanol return rather than a lowered alcohol content?

Would some bubble plates do it?

Yah pass your vapor over 4a beads…

If you add some packing into a column before it hits your condenser it should do the trick

Would a peristaltic pump be able to pump in a winterized mixture to the top of a FFE?
Yeah absolutely, I recommend vacuum but either works
Is there a specific kind of peristaltic pump you guys prefer? Also, what kind of tubing should I use?
It certainly has more tubes than the 6" one they sell. You will be limited by the 8" clamp’s pressure rating. This should be a non issue for a still.

I like santoprene. Should work well with your vacuum application as well.

Does anyone here have a filtration system set-up directly to their FFE?
Like something that filters a mixture to be winterized and carbon scrubbed does anyone have that kind of filtration system hooked up to their FFE?
Wait now I’m confused. Should I be using a smaller dephlegmator if I’m only using like a 6×14 collection pot (6×12 spool or jacketed spool with a jacketed 6×2 splatter platter) and a 6×18 recovery tank
I would maximize the condenser if your are shooting form the hip.

Beats doing the math…

Says you. The math is my favorite part.

Well what I’m wondering now is for my safety not just for efficacy. Is would I need to match the amount of vapors coming in from the main hot dephlegmator to a bigger collection pot or am I gonna be safe running a 6×6 main hot dephlegmator with a 6×14 collection pot?
That depends on your temps and your condensing abilities.
You’ve seen this graph a number of times.
What does it tell you about the pressure in your collection pot?
What will your system do if the defleg is set to 70C & you close off the recovery side. Assuming 100% propane?
You might not have seen this one as often…but you’ll need it to actually answer the question posed (first one doesn’t go high enough).
Hint: pretend you’re doing this in an ETS MEP which has PRVs set at 450PSI
