We try to leave around a foot of room on average. Ill admit that sometimes it does get to that over boiling level.
That was the case with me. Not often but when tank way full was my thinking. Then i set the sieve higher and nver had issue after. Im not alchol guy but happened to me in roto vape puking ovet a couple times when winterizing.
Whats ir thoughts on the 180 temp? That doesnt darken the oil?
I made an extenstion up if u can see in pic?

The reason that were cooking at the 180 is to process our runs in an hour and a half. We do large batch runs. Average single run is usually around 120lbs of biomass or higher.
This is our recovery set up. The reactors are daisy chained. Left one does the bulk of the pull down. We transfer to the one on the right to finish the pull down on before we pour. Recovery runs to those two skinny desiccant towers. We only pull recovery on one vessel at a time so both of those towers are active on either reactor at any given time.
what pump are you using to pump the water @ 180f?
Those moleseives look small for runs that size. Some people here have talked about running expansion columns prior to sieve to catch any hash that makes it over.

Pro tip from the wizard yesterday…
Or you could read of Liquid separator instead of molecular sieve
…And just put one in front of rather than instead of your molseives.

Thats not a bad idea at all. Thank you!
Ill definitely be looking into this. Thanks for the links man.
I can see the extension on it. We have quite a bit of length between our reactor and our towers. That’s one of the reasons this is driving me nuts.
I believe they’re ground fos? I’m not exactly sure. Ill have to check.
use larger lines/piping to your condenser to keep yor vapor velocity down

Whats the hexane for? Are u recovering the hexane or are u saying it’s your chilling fluid?
Also that light behind your vapor manifold is kinda sketchy

Your seives look a lil lower than ur pot? Im pretty stoned atm. A continual slope upwards with the lines. Doesnt have tob verticle like i did. If im seeing correctly lol length isnt issue i found in my case it was the upward slope and most likely from when i allowed collection to get to high in tank.
Nice setup for sure.
How long a run take ?
Im setbup to run 120lb at a time. I isualy run about 60lbs. I need better pump or do hybrid system. This passive is catching my attention

It’s commonly referred to as bumping. You’re letting your reactor get too full before you begin recovery. Either your solution is too cold and foaming excessively, or too hot and recovering too aggressively.
If you just had a small amount building up over time I’d be more inclined to believe it was the result of an improperly setup mol sieve.

We used the hexane and alcohol to flush the condenser/clean it. Trying to prevent a wax build up inside of the plates.

We run recovery as we push into our reactor. We’ve definitely done some bumping here and there. What concerns me is that even with a lower level in our reactor we still seem to run into the issue even with a fresh set of vapor lines, valves, and desiccat towers hooked up.
I can try a shorter Line to maybe apply more of a gradual slope to the setup for sure.
Thanks man. Yours looks really clean itself. From the time we start pitching solvent to the time we kill our recovery and our ready to pour on 120lbs its an hour and a half give or take 5 mins.
Passive recovery really changed the game in our overall production. We almost instantly doubled from using cmep pumps and 2 MVP pumps.
We run 1/2” currently on our recovery setup. You think jumping up to 1” would be better?

go 1.5 and add a shelltube above your first evaporator

I have hard pipe 1.5 going to manifold for each pump to 3/8 for ea of 4 trs21.
2 pumps for ea 3/8 line.
Iv herd 3/8 coil cools better than a half ?
Depends on pump.
I think slope is key . my vertical 1.5in to seive only adds up to around 24in. But u do need enough rise to be more than what possible burbs over
