Pressurized Closed column extraction

I like to grind my buds with a coffee grinder and dry for a day or 2 under a ceiling fan. Don't believe there's much if any moisture left to freeze. Not sure why some are saying less cuts the better? I'm pretty sure that I'm allowing the chlorophyll to decompose more this way, but don't mind because I care more about yield than color. I also seal my stuffed tubes in bags before freezing at least 24 hrs. This way no moisture from the deep freeze can get into my material.

With that method I can get 112g into my 100g glass open tube. I run 2 cans of Newport through it. Then I use a straightened coat hanger just long enough to stick in the lil hole all the way down to barely touching my filters. Stir it up real well, flipping up and down banging with my palm to get my material moving around as much as possible. I do that between every can until butane coming out is totally clear. Then I remove filters, stirring and shaking from the big opened end of my tube. Filter it back up and proceed the same way until clear again. With all that extra work of making sure every speck of material has been stripped, I'd like to believe that my open blasting yields just as much as a closed tube or whatever you guys call these things. However, I definitely use WAY more butane! What do you think justugh?

Also I'm wondering how much you guys paid for this setup?

Peace be witcha brothers!

I think I paid under $180 for my set up

When we were still open blasting, we had our tubes made by a scientific glass house, which cost us $1 per inch, plus $10 to flare one end, dome the other, and give it a full anneal.

Know this thread is kind of old. But those of you experienced in using this extractor, after pulling the vacuum how do you go about putting in the butane? I am having an issue with having a 135g closed column pressure extractor but after I pull the vac and start adding the butane, I can only fit maybe 3/4 of a 400ml can in before it stops. I have a 4 cfm 2 stage pump if that helps any. Am I opening the valve too much when putting the butane in? Any help would be greatly appreciated.

It depends on how much you pack and how long you pull a vac I got the 180g setup and can get like 2 cans in sometimes 2 and a half

How long do you usually pull a vac? I tried to go by how the pump sounds like the video says but if I go by that it's almost like I pulled a full vac in less than 10 seconds. I regret not getting a gauge.

So when using this type of extractor does the whole 1 can an ounce rule go out the window, or am I supposed to do this repeatedly until I use the right amount of cans? Going from using like 4 cans for 112g down to 3/4th of a can seems I may be leaving a lot behind. Are you doing an ice bath as well?

Sounds like your packing to much man. I get like 50-85g with my 180g setup and get better yields than when I pack 100g into my tube, you have to leave room for the butane although the pressure will suck some in there has to be enough room I often find after the first can slows down closing the top and shaking the can and continue adding that can while slowly opening the bottom for more butane to flood in. I do not know for sure if this helps but I have gotten better yields this way for sure. And I try to pull at least a minute and a half vacuum pull on my setup.

Ah. Well I've put about 60 grams in the 130 and got the same results as far as how much butane I can fit in there. So now I've just been trying to research if what fits is enough. I still haven't found out if doing it this way changes the 1 can per ounce general rule. I tried frozen cans and extractor as well as material and none has changed how much butane I get in it. Meaning I'm still unable to even get one full can in. I'll keep trying. I blasted almost a p trim and got back like 12 grams. I abandoned the pressure step completely and just used it to open blast and got the same yield with a quarter of that so I'm really doing something wrong here and all the videos and reading I've been doing I haven't figured it out lol.
I even went and bought a different hose set up to be able to use the bottom valve like I've seen in all the videos ( I was using the top previously because that was the only type of hose I had. Thought that would change something but nope.

I feel you man. I've blasted only like 6 times since I got the closed column. 1 time I got 2 cans in. I think the first time.

I never over pack or compact the weed. Just enough to keep it uniform so very little compaction at all.

Next few times I was getting g like you said, half to 3/4 can. Then I would open and close a million times and sometimes even let out some pressure just to fit more tane in.

My yields on the first time were close to 20% the next couple times they were around 12%. So seems to me whatever causes the back pressure is effecting yields.

In all honesty, I'm just sick of using it. Some how, some shit happens I feel everytime. One time I kicked dirt into the tray cuz I forgot to close the valve before taking the tane can off. Almost def'd myself lol (yes I know that's my fault and not the extractor lol)

I just feel the videos you watch seem easy and yield a lot but in reality, it doesn't for whatever reason. I've tried less weed, longer pressurizing, ice ect ect.

Plus, I never seem to get really blonde or golden type of wax. No matter my material, it comes out golden but only when you look at it though a light. Looks brownish otherwise.

I was hoping for like honey color but still looks like open blast material at the end.

I used top quality buds and trim and I never let my tane sit in the extractor forever so don't know why that is happening.

Just some random thoughts of mine and letting you know there are more of us out there lol

Vaporized LPG is keeping the liquid LPG from entering, because your system is unvented.

Chill your column and butane below 0F before injecting, so everything stays liquid.

As far a quality and color. I don't advise soaking if you are concerned about color, because it increases both the pickup of ~C-30 plant waxes, and anthro cyanin plant pigments.

Yeah one can one OZ rule don't apply when you pressurize the tube for some reason less butane fits. Don't know the science behind it but it's one of the Advantages of using pressurized columns. You get the same solvent action with less butane applied. Good luck happy blasting.

Lol I would love to get two cans in at this point. But yeh it's beyond frustrating. What makes it worse is I've been only able to find one video online where someone actually putting butane in the column haha. Usually when I get stuck on something I can find video, instructions etc. I've had people tell me to pack it super tight, pack it loosely. Freeze the column but not the butane, freeze the column and butane, don't freeze anything, freeze everything.

I feel you on the color thing as well. I've been getting a brown color that looks good in the light lol. Figured it was the material but it was the same when I changed it.

Thanks for replying, I feel better knowing there are others with issues like this. I thought I was just a complete goof and couldn't get it right.

Thanks for the info. Good to know. Actually makes me feel better due to the amount I've spent on but am so far.

@g84mad Haha yea it sucks. I feel stupid. I've read and watches everything I can and still get fucked I feel. It's at a point where I'm going to try my hand in making full melt dry sift.

If you figure anything out or need to message me, feel free. I've made a ton if bone head mistakes that you could maybe learn from....lol...except blasting indoors and shit. I'm not that dumb. :)

@Fadedawg I've tried not letting it sit at all and when I do I've only waited about 5 mins and never got any green or dark looking shit, just never any of that really golden looking wax. Only gold when I look at it under light and I've tried spreading it as thin as possible. Sigh.

The pressure increases solvent power so if you leave your material in tube to long get darker oil. Higher yield but more junk imo. So I just use it to open blast with it now.

And for blow back put coffee filter on on butane port as well
