So I’m most likely gonna obtain a couple of dephlegmators at some point and I’m going to make a pot still with cls parts to make eho.
The thought I had was that if I set the water on the jacketed base/boiling flask for 86°f and use a dephlegmator going upwards diagonally and that was also set for 86°f, would I need a larger cold dephlegmator as the condenser or can I use the same size dephlegmator as the hot dephlegmator?
I figure using a hot dephlegmator and raising the vapor temps before it hits the cold one would make it distill quicker for some reason
Why would you use a dephlegmator at all if you’re not trying to reproof? Unless you are trying to reproof, then you need to pack that column; but the packing might be enough reflux to remove a few % water.
If it’s just solvent removal run that shit on a tiny path to a big condenser for high efficiency.
What I don’t understand about FFE is how does the oil leave the dephlegmator? Does the heat make it drip down? I know the basic principals of how a standard one for juice manufacturing works, which is pretty much the one @Future built in his open source FFE thread but the video I watched never really explained how anything leaves the hot condenser. Or is the heat from that dephlegmator just making it distill quicker?
Ditch the vapor recompression, for a simple evaporator you will not need to employ that.
simply preheat the feed and spray down the throat of a heated tube and shell. You can build the evaporator as a current or counter current unit, that determines the placement of the condenser.
see the image for current vs counter current.
The principal is relatively simple, heat one tube and shell to boil the feedstock, separate the vapor from the entrained resin, then condense the vapor with the other tube and shell. As this is occurring you will need pump out the resin and condensed solvent out of the system.
