evaporate all the butane off outside, then I boil some water on the stove, or just below boiling point. the set the oil dish into the dish of boiling water and watch the oil bubble... essentially getting the bowl real hot.

you can also spread it out very very thin and put it in the oven at a very low temp (not sure exactly) and monitor it.

I have been doing it (wrong some would say) for years without a vacuum, and possible under purging. as have thousands of others. its not critical that you use a vacuum. I would estimate that if you do the very hot water trick to cook off the butane, it gets around 97% of it out. then if you put it in the oven or boiling water after all the visible butane is gone and its an oil not a liquid. it gets it to near 99% I would estimate. then the vacuum purge takes out that final 1 or 2% and makes it super pure.

time is pretty important, as well as keeping it constantly hot/warm (approx 100F), and thinned out over a large surface area. thin it out, put it in oven at 90-120F or so for maybe an hour or 2 (monitor it just in case) and see how that turns out. should be good enough to go by then (by my standards... im no hippy though. 98-99% is good enough for me)

^very helpful thank you, ill do the initial hot water baths outside, once again inside in a HWB and then in my oven.

one more q, when it comes to your extracting tube what dimensions do you prefer ? i have a .5" diameter x 1.5' length tube that i could cut down (probs only gonna make 1/4-1/2 o batch) but then i thought hmm maybe a smaller diameter and longer length would extract better. I have nothing scientific other than gut feeling to back this up. maybe since oil has to travel a greater distance... well idk. the right way to do this is test each tube side by side maybe ill just do that, unless anyone can lend expertise ?

 

[vacpurge]

I personally find that longer, skinnier tubes work better than a short fat fucker... it helps if you imagine it to the extreme. Imagine a 1 inch diameter tube thats 2 feet long.. would work great. now imagine a tube thats 2 inches tall but a foot in diameter.. basically looks like a frisbee.. it would suck. so with that theory.. skinnier + longer = better. .5" inside diameter might be a little small though.. its hard to say. it could work I suppose for small batches.

if its normal ol tube, which it kinda sounds like, I would recommend NOT using it. there is special plastics to be used.. or even better. glass or stainless steel.

while you dont have to invest in a fancy expensive vacuum pump, its very important that you got all the other right tools.

and I cant stress this enough. spray the butane, and evap it outside. no sparks, no nothing. dont flip any switches, no previously smoked, still smouldering cigarette butts. no friends showing up with a pre-lit fatty. no anything. even static electricity can cause a explosion. just be extremely cautious for 10 mins until the butane is evaporated and dissipated.

I just met up with a guy ive known for a while... and I never realized, but all the skin on his arms has been skin grafted. turns he blew up butane oil making it indoors once in a bathroom. melted his pants to his legs, extractor blew up the palm of his hand, ruined the house, it was bad. the fan was off, he turned it on after spraying several cans, and boom. the spark in the fan is what did it, it wasnt intrinsically safe, which is normal for a bathroom fan. it blew all the doors and windows out of the floor he was on, he said it lifted the fuckin roof and cracked the connection where the wall meets the ceiling. it can be some serious shit. do it safe and do it properly, and youll absolutely love it.

Our experiments support that diameters under an inch were more efficient than larger diameter single pass columns. They are easier to reliably pack so that the butane doesn't just find an easy way through and the injection end has better coverage. We still add a wadded up coffee filter in the injection end, to dissipate and spread out the butane flow.

 

[vacpurge]

I dont understand why you would want a wadded up coffee filter at the end though. seems like it would stop all the intense butane stream and just rely on drips??

what so you guys find best is for the exhausting end? my extractor has a screw on cap with 5 holes that are very very small. about the size of a small sewing needle and there is 5 of them. should I add more? plug some off? or what?

To reduce/minimize blowback when changing cans if you run open, in addition to spreading out the stream of solvents.

1 question, so for my 1st bho, i dont particularly wanna pay for a vacuum thing. would multiple courses of whipping/stirring and heating (performed in a gentle manner with the utmost care) be sufficient to remove most of the butane

My reasoning is that many people are unwilling to even spend the $150 on a pump, and would rather whip terrible hash oil than spend any money. Yuck. No thanks I don't want to try your "budder".

Told ya. People aren't willing to spend the money to be safe. To each his own, though.

Glad I can purge in a 6000 dollar commercial food vacuum sealing machine...

But if I couldn't, I'm sure I would make the cheap harbor freight 2 stage work for me. I blast into Pyrex, and love that I can just put the whole pyrex dish inside the cryo-vac machine

 

[vacpurge]

hmm. interesting. ill have to try the wadded up coffee filter thing next time. when I pull the butane can out, I pull out slowly and aim it away (here come the jokes) from the dish, there isnt usually any major pressure, but it does sometimes spray out a few tiny chunks. thats when using my small honey bee extractor.

I have a larger one "queen bee" that I can fit 120 grams in. it built up some MAJOR pressure. took 1 full can before anything even came out. that was a first. I was trying to be quiet and make the oil sneaky on my balcony, and when I pulled the 2nd butane can out, it sounded like a jet engine was starting off. so I pulled the next one off slowly, and it made a loud whistle sound. not cool. maybe the coffee filter trick would have worked. im not using that big extractor anymore though! small and skinny one works way better

I've been asked to perform an extraction service by some reputable people and they have been working w Eden Labs for 8 years. They asked me if I could extract caffiene w only co2 and water. So I said sure. The very first set of extractions I did showed them I knew what I was doing and it landed me work in a field doing what I love and yes get recognized by Eden as having skill in the art.

Hello brother Oilmkr, I just read your two starter threads and thought I recognized your style! Different names, different forums, eh?

SCFE CO2 extraction of caffiene form coffee beans is old news, so a little research may save you some experimenting.

Good to see that you are still extracting for hire, and trust you still have a sponsor funding your research? Have those CO2 SCFE commercial interests worked out as well as you were hoping?

Yeah these guys fund the R&D. They love the bitter kola extract and even get oil from me @ club prices! There is a whole lot of coffee extractions to go by, yet nothing on garcinia kola extract. UCLA is doing the 1st human study on the benefits of eating this extract. Wide claims like mmj, one claim is it gets it up for men. Another is it works equally as well on women. Its a very interesting product to work w and I get paid to play. I love my newly found career and it looks to be a great field to be in right now. Here was 5 lbs of plant matter that smelled just like coke.

i have never heard of bitter/kola extractions, ive barely heard of any extractions, you seem to be an extraction connoisseur.. do you have other journals in other threads/forums you can send me to to read? i feel you have mentioned/discussed plenty of good info across the web. could you please direct me in the right location! would much appreciate!

made some bubble hash today and it came out green. anyone know whats up with that? used a electric beater to mix for about 20 mins and used bubble bags.

I think you might have let the water warm up too much dude. Anything other than ice cold will leach chlorophyll into the water

 

[drolove]

had ice in it all the way through. some of the trim was pretty fresh. im thinking thats what it was.

Green is chlorophyll, which usually comes from overworking the material or using a beater with too much shear action.

It can also come from fresh green material that isn't frozen first, to lock up the cholorphyll in ice.

You might try freezing your fresh material longer, and letting your ice bath and material sit longer to chill down before starting the beating.

cool shit, thanks for the help on that guys!

Yo, I want to say what up to Roger and Eden Labs in Seattle, where my tap water sample smashed on their extract, and I did what they said couldn't be done, and pulled out a crystalline w just water and co2. They know me as the guy in Los Angeles who pulled a brown crystal powder and they have claimed to do just the same yet still no response to my numerous entries submitted. As cosub2 extractions. Wow I really went beyond my expectations w this youtube video I released over a year ago. None the less, Eden went back to the drawing board and am getting the attention of who I thought knew the biz. Thank you Eden Labs for your analysis.
