You know Zac lentz from illuminated extractors. I think he pumps his jackets full of lpg then recovers them to cool them. I think lpg at 5.3psi super heat is - 50c. So as you recovering it gets colder and colder I guess until the lpg is all recovered or maybe he refills it by injecting threw a orfice like a txv valve or maybe a prv completing the loop. Not sure but it’s really cool. I picture it like direct refrigeration with you material column jacket as your evaporator. I think he has found a way to reverse it and heat the columns too.

Subliminating dryice has me intrigued.
I’m gonna throw a bucket of dry ice in a spare 12x25 solvent tank then run a line to the jacket on the material column then pull vac from the other port on the column and see. I’ll use a vent valve on the 12x25 to sweep so nitrogen in to push the vapors threw and cause some turbulence. I’m tinkering today. It maybe get cold enough. Not sure how much ice it would take.
I had an idea where I was gonna put a lid on my recovery coil pot and direct the off gasses co2 into a radiator then outside. Then place the radiator on my booth intake vent to kinda provide some climate control for the booth.

Please use a prv on the vessel the dry ice is in 
no need for nitrogen
You will basically flash evaporate the dry ice
Would be nice if cold vapors would cool the ss faster than liquid yust like steam heats them faster than boiling water

Our tech maintains the liquid level at whatever temperature you are operating at. Standard system gets down to -80c in about 10 minutes or so and -50c is typically achieved in 3-5 minutes. The colder it gets, the more cooling capacity you get - which is the opposite of traditional technology.
Yeah we can generate heat as well on demand. None of our systems use a hot water heater anymore and I am really close to being able to run the entire system on nothing but itself.
We typicality see a +50c to -50c or a -50c to +50c transition in 5 minutes. U.S. Patent Pending.

Steam has more enthalpy than boiling water (superheat), but at the same time, sub-cooled liquid has less enthalpy than it’s vapor at the same temperature.
The other half to this is density of the gas and volume of the density.

That s what I was thinking
So now the question arises how much faster can cold vapors cool matter stainless steal biomass any matter
Think there is an interesting phenomena that can be exploited a crossover from freezedrying and steamdistillation with this
I ll start some r and d on this somehow like co2 dry ice more than Ln2 for terps
Darnit so much to do so little time

Yeah that’s forsure. It’s a old solvent tank we use for redesolves. It’s got prvs and gauges on the lid. I was lazy and not as energetic as after running a couple rounds so i didn’t attempt it. Well I was doing a couple runs today I threw 10lbs of dry ice pellets in a vacuum oven. I set the vac oven to 71f and ran a 3cfm vac it didn’t budge on temp. So 10lbs won’t even fight a 500w oven. I deffinatly don’t think it’s vapor would cool any kind of jackets now lol.
1 kg of dry ice is 509 liters of gas
So to try this you need a high cfm pump to pull out the sublimating gas and pull vacuum

I just used a 3cfm. It pulled vac. Not completely but it pulled down. I was expecting it to build pressure faster then I could vacuum it out but it made down there before it equalized out. After watching for bit I needed the oven back and gave up. You can deffinatly pull vac on dry ice in your oven tho just not completely.

Thx and interesting let’s yust update each other on findings
The concept of cold or hot vapors to cool or heat systems is a nice one

Forsure. Deffinatly keep ya posted. A little off subject but, Have you heard of using a coil in shell HX on you rig to cross you lines between you material columns and crc with the coil side and run you hot recovery vapors threw the shell. It works really well to precondense butane into a 50/50 vapor/liquid before you main condenser. It also heats up your extract exiting the material columns before it goes into the crc so you can ectravt cold but filter warm making the powder a bit more efficient and it also saves me 25 percent on dry ice. I used a 6" triclamp coil for solvent tanks with the dip tube cut off inside a 6x48 spool. 32ft half inch coil. Works amazing. Just thought I’d share. Boomtown is the one I got the idea from.

Let me throw this idea out to ya. Terp harvesting. Load up a column, heat the jacket to 120f then run a line to from the bottom of the material column to a coil in liquid nitrogen then from the coil to a diamond miner in the same ln2 pot as your coil then connect your vac pump to the miner. Slowly inject some nitrogen to sweep the material column pushing the warm terp vapors into the coil then into the miner for collection well still maintaining a vac. Then run the column and extract the rest.

Where I worked it was 60min soaks on co2 chilled material columns. I will say 90% of the time material being run was the culprit for problematic results. 10% of the time it was fresh frozen that had thawed and been refrozen. ice ice baby, no good.
Anyone know the best method of drying, and packing, and timing of column blast? I only have access to cured high quality buds. Right now I’m doing closed column with open blast into Pyrex, Mason, or Ptfe paper…. It’s always dark and it’s always a bit harsh. Doesn’t matter how many coffee filters, organic cotton, Ashless paper, and even cutting micron filter press sleeves and cutting them to make filters in a 3in Denard extension filter piece dividíng it (6 larger holes)
1.5in column with dewaxing sleeve.
Am I soaking it too long? (I’ve done gravity immediate blast and up to 20 mins soak. The two are both dark, with the latter giving me 25% of green gold brown oil color turning black once a couple inches thick.
TLDR best way to close column blast primo buds, and no residuals? I’m about to buy a CRC kit hahaha if I don’t figure this out
Green is generally a sign of water…
As you’re not recovering your solvent, you must be getting it in there with your “cured” buds…
Where did you acquire them?
How long ago were they harvested?
How have you stored them?
Are you using the dewaxing sleeve?
Warm butane will get the goods, but it’s not gonna hit your target.
How do you plan to get your saturated solvent through a CRC?
You’d be better off upgrading to a CLS so you have better control of your extraction first.
What temp are you purging off solvent?

honestly never really soak just run a bunch of gas through slow n cold never had any issues on return % and make some top shelf extracts
lore suggests it works better if you use liquid…
Are you using a CLS @N710ate?
