We do freeze the tubes too but have never freeze the butane; been wanting to try that.
We've had good experience with blasting until fluid starts to come out. Then stop blasting until the fluid stops then repeat until fluid is clear. (You want to keep the can sealed on the tube to keep the suction in the tube.)
This leaves basically no "excess" butane in the collection chamber and manages the use of the butane very well.

you need to be sure and set up some side by side runs.. its well worth it to invest the extra time to see the results..
please, i dont think im crazy. try it out, throw some cans of butane in the freezer at least over night... should get plenty chilly, (put your freezer on coldest setting!)
need to be using exact same material for each test though, along with exact same packing density..
just make the runs completely identical, i would still recommend you insulate/freeze both tubes/runs, just change the butane source, (cold/room temp)
compare! give us results!
i kind of want to test again... but i already did, someone else pleaseeee.
if i dont have chilled tane, i dont blast... its worth the wait :]
i swearrrr the cold helps.. i have a hands free blasting system, so im not even sure if the rate at which it pours out is slower than room tem por not.. i just goo, and judge by sound of can.. after each can, i let it sit still pluggin hole , i spray first one, let it run out, wait about 2 minutes..
spray 2nd one, let it run out, basically wait till it gets pretty down far my tube.. wait about 4 minutes.. once i have tane exiting my tube, its pretty much a simple blast through with my last can..
if i could freeze my packed tubes, i def would.. but thats no option, i would need a huge freezer..
so i got with wrapped tubes., chilled cans..

I don't blast, my butane is traveling through a closed loop system. At the beginning of the extraction the butane entering the system is too cold for my thermometer to read (lower than -27F). The result of the extraction is a product with consistency similar, but not nearly as brittle, as the result of an EtOH winterization.
Anyways what I have gotten out of this entire thread is that extreme chilling of butane will only decrease dissolution rate, and does not cause less wax to be dissolved like I hoped was the case.
For exact knowledge you need to extract the same material at different temperatures and to make a comparison of the %% of separated waxes.
In my amateur experiments with thermos and freezer I saw flakes of wax immediately after the dissolution of the "warm" BHO in ethanol, but they did not appear on dissolution of -20C BHO.

i wished it was the case to man i was looking at those dry ice extractors

This isn't all about winterizing, but the subject of deep cold comes up over and over again throughout the video. I know allot of you don't have the glassware to do things like grape alcohol reclaim distillation but there's enough in there to give you a glassgasm or at least tek engorgement. It brings up allot of subjects fadedawg is covering in recent threads, like cryo freezing solvent before blasting. Im wondering if super cold extractions + dewax tek would be enough to get you more terps with less fat that maybe Absolute's arn't as coveted absolutely.

What a coincidence!! I just watched this last night. I noticed the distinct omission of information relating to their blasting process, but I did see that they have a huge collection of glass tubes so I am assuming their primary extraction is with canned butane.... Tek engorgement is right, I never even heard of a turbo molecular vac pump but now I want one too! But first things first, gotta get me one of those cryogenic freezers
Does anybody know whats so special about the grape alcohol they use? Regardless of what it was distilled from, isn't EtOH just EtOH?

I know your not serious about that cryogen freezer Im not sure but I think he spoke out of term. I didn't think cryo was -50c I thought it was way way colder.
I have one of these small unit's more like a cryogenic beer pitcher than a cryo freezer and wayyyyy cheaper. In the meantime for most 5 bux worth of dry ice and a bottle of ethanol will do same job just more fiddly.

I don't think -50c is technically cryogenic but you will be hard pressed to find a freezer that passes -80c, even in generously equipped biotech labs. For true cryogenic work I believe they are using liquid nitrogen.
Unfortunately you are right that cryogenic freezer is out of my budget
I just got a chest freezer though LOL so I can pretend 
Btw if you do super cold extraction the waxes precipitate in the butane and can be filtered out. The principle is similar to winterizing in the freezer overnight. Usually when people blast in an open ended tube the temperature of the solvent does not get as low as it would as leaving a container of EtOH in freezer overnight.
When I extract with dry-ice temp butane there is a lot visible waxes clumping in the collection vessel, so I believe chilled extraction is indeed a better way to get less fats and more terps. The reason being that to purge out EtOH (Boiling pt = 78C) you will lose a lot more mono/diterpenes than you will purging out butane(BP = -1C).

Does Dewaxing work with all non polar solvents, im wondering why winterizing to get the fatty's was the rage six months ago and now they fall out with allot less work by just getting colder. It would seem if the tube and butane were cold enough they should of never made it pass the coffee filter on the tube, It must be the evaporative cooling that's taking the butane pool colder than it was in the tube itself. I've tried dewaxing with another non polar that's more stable at room temp and it didn't precipitate anything at -50c. I dunno if it's where butane stands between polar and non polar that gives it that capacity. Seem's like dewaxing it more a window of opportunity but you never know if you got it all.

So what temps are people getting down to in the pool of butane for the waxes to fall out. I let my solution sit for 3 hours and nada, i watch a youtube video and he's just spooning it out by the ball. Then again i ran a pound last night through the winterizize stage and only got back maybe a gram of fats, that's why i wondered if in my case there not making it out of my tube because im pouring -50c fluid. I wish this shit was googlable but it's also exciting how raw and hand to hand the knowledge is.
Like would it work with hexane or it carbon simplicity that allows it. I guess before winterizing the dude that just did large loads and removed by fluke had the smoothest product. Those waxes make for great foot cream, but i dunno how long a filter full of wax keeps.
