I like that…
Jacketed material column, filter stack, Short section of jacketed spool, flat cap
That would work great…how did I not think of that.
And I planned to have my plumbing set up so I can just vacuum down the jackets while running and then flood with hot water during recovery. Drain water back to reservoir before running column again.
That would be a really to put together I’m sure. And the vac jacket would totally work for keeping cold during the extraction
A good way to soak the material is by hooking up an expansion tank(25lb solvent tank on dry ice) on your lid to eat the vapors thus allowing the solvent to continue to flow in until its flooded. Then pause it to let it soak. Now you can flush through evenly with your solvent once all the material is saturated and push through.

That is a legit idea. The vapor will no longer be trapped in the column, allowing a full soak.
I was hoping much vapor was not making it into the column. The 6" column lives packed, on dry I’ve for at least 12 hours. I hope that when the chilled solvent gets to the column there isnt much vapor at everything is cold. I could definitely add a port to my 6" cap to vent to a 25lb tank.
I have a 6" collection lid, I had considered using it so I can see into the top of the column. But with no spray ball, I was worried about poor coverage. I thought I could machine and weld a diffuser right at the bottom of the dump tube indide the lid. That way I could shoot solvent down the center and get an even spread, and view the whole column flooding process.
Being able to view what is going on will be very useful. In my profession, we call this OQE, objective quality evidence.
I am 3/8 lines. I was thinking a half inch line would be nice, but then I need to get a new coil. My tank already has 1/2 valves on it.
I’d like that upgrade, but I’ve dumped thousands into my shed set up. One day. It is coming along though for a fools attempt at a big boy system.
My little machine is bidirectional and the times that I just started at the top and ran down did not yield as well as using the bidirectional feature to start at the bottom and fill to the top… let is soak a few and then switch to a downward flow
That may be suitable. I imagine combining a bottom flood, with @Waxplug1 tank idea to take all the vapor out of the column, would be very effective.
I am going to do a consultation for a local guy, who bottom floods, and then pushes from the top. We are going over the CRC process and application. So I will soon have some bottom flood experience, and I may move that direct on the 6".
If you have a dewax column u can expand into there as well. I use a manifold to send the vapors here and there 
Im probably wrong but the way I view lines is that it all goes in and out of a 1/4 at the butane tank. And my swagelok valves get pricey the bigger they are.
My butane leaves my dipstick at 3/8” and on my recovery side the butane re-enters my solvent tank through 2x 1/2” ports.
I’m confused by what you are saying. Are you talking about a carbon steel tanks fittings?
My valves on my tank a 1/2" valves, no 1/4" anywhere.
When I run 3" columns, my injection diameter is about 1/4" though as i have a .049 wall hard lined injection manifold for 3 columns in parallel.
Purge labs makes or imports them however you wanna look at it.
Yes, I dont even like the idea of using triclamp on a propane tank.
Dang, bummer.
Stainless tanks for life. Lol
Not saying I won’t use them for solvent storage, but besides that…
I did get rust in my old tank, now running a mol sieve
Hi,
are you weighing the material into the column?Where are you pulling your numbers for yield?
One thing I see with going up in diameter is the compaction of the material. Larger tubes cannot be packed as densely as smaller diameter tubes due to the amount the force you exert is spread out more.
true, the only factor that changed is the diameter of the column. The culprit is probably channeling. where are you pulling your yield #'s ?
Unfortunately, my yield numbers are coming from basic observations. Material weight in, extract yield out. No potency or anything.
I have experience running my 3 inch columns. Moving to a six inch column, I see my previously recorded data no longer predicts my yield for me.
Running my 6" side by side with my 3", same material, I see a loss. I think it has to do with channeling, and application of solvent to biomass…in my case anyway.
Have/can you throttle the output from your material tube, so as to create pressure shifts and differentials within the material tube?
There is a system that operates like a tumbler ,yes its kinda sketchy having 3 30+# rotating vessels filled with equal amounts of hydrocarbon
