Hash oil machine!

THE MOON RULES --1 · voted for the moon

A while back swim and its buddies where in a pickle. They where so sick of blowing outrageos amounts of money on butane for THC oil extraction. For a good extraction they had to use at least (2) 5.82oz 165g cans of butane per 1/4, 1/2oz of cannabis. With mexican brick cannabis they would yeild on avaerage 500mg to 750mg of pure amber, honey colored oil, per 1/2oz, that had a smell of top quality cannabis. (there is no reason (unless economic reasons are of no concern) to use top quality cannabis for hash oil production other then bigger yeilds, but price versus oil conversion are not economical at all) Well the starting material is cheap, but the butane adds up. Plus prolonged exposure can make you feel pretty sick and high (not in a good way, brain damage high). So they came up with a machine that would be cheaper to run.

The machine consists of a propane tank (full of fresh propane)

A threaded metal elbow attachment that will attach to the propane valve, you want to face the elbow down. (hardware store, go to plumbing)

Just imagine your tank, with an elbow extention (with two threaded openings) conected to your valve, and the other part of the elbow facing down.

From the threaded elbow attachment get a steel pipe the same diameter of your elbow valve (roughly the same diameter as the propane valve)
Get a few feet of this tubing 3-5 feet. Get the top and bottom of the pipe threaded from your hardware store. If they ask any questions just say your building a custom BBQ, sounds stupid but it kept them quit.

So now you have your tank, your threaded elbow pointing down, connecting from the propane valve to your threaded steel pipe and now you have this long pipe pointing down.

Next get a steel cap to fit the threaded pipe

Take the threaded cap and drill a salt and pepper type design in it from the inside out.

Cut out some coffee filters place them in the cap, then stick some steel screen cut to fit ontop of the filter paper.

Get a big ceramic bowl and put on floor just under the end of the pipe with cap on.

Now all you have to do is fill the pipe with cannabis (fill it good, don't compact it, just fill it till its nice and firm) put the endcap on and turn on the propane and your in buissness!

You could also put a valve on the end of the steel pipe and attach the end cap to the valve so you could have two valves

Make sure you have a good table to put the tank on. You will need some phone books to adjust the hight as the ceramic receiving bowl fills with propane. Don't let the cap go into the collecting propane. Experiment on the flow of gas.

I don't think I need to point out that this must UNDER NO CIRCUMSTANCE BE DONE INSIDE! You will blow up "spun" style.

This is a very affordable way to get great hash oil that is very very good, from absoulute crap cannabis, for not that much money compared to little butane cans.

very clever idea but I must be missing something here.How does the gas condense in the pipe so that it drips out liquid?

It seems that a dual valved set up with a modified tank set up to deliver liquid into the pipe extractor would provide a residence time of any duration. This should greatly reduce the propane use and hopefully not dissolve everything else in the plant at the same time.

Must try this just for the hell of it.

How long does it take to pass thru the pipe per your setup?
Also are the oil dissolving properties of propane essentially the same as butane?

Have used pentane for other herb extractions which boils about 36deg. This is the low boiling petrol ether 30-45deg stuff.

Hi!

The cool things about using propane/butane are that

a) the "gas" (propane/butane) is already liquid when you buy a tank of it, it just becomes gaseous as soon as it is released from the pressure bottle (think about gas lighter refill, dude - that's the stuff we're talking about here, and not hydrogen or methane or HCl - which cannot be compressed into liquid form that easily... Wink

)

b) the speed at which the solvent passes through the "HPLC" column is amazing - it develops an enourmous pressure on its way down, and this causes it to travel downwards at the speed of 40cm/<1sec. Laughing

- and this leads us directly to the next point:

c) no dual valve setup needed, just a fine screen to catch fine plant matter. The "solvent" becomes gaseous anyway a few seconds after it has left the column - since it boils at below freezing point, and has a very low vapor pressure. Therefore it evaps immediately, and only pure hash oil with more or less boiling butane/propane will sprinkle/spray out of the exit valve.. Cool

d) maybe hexane is not; but butane (lighter refill) gas is very selective and produces clear, yellow oil - which is immediately ready to use (no solvent has to evap anymore)....

e) you could use a very fine exit valve, and spray the resulting finely vaporized oil directly onto low-quality weed to improve it "just a bit".... Wink

AFOAF of mine has done this with PU drain pipes with great success BTW, but please, please: do it only outdoors, on windy days - and avoid sparks like the pest....

This is a commercial demonstration video for a commercially available supercritical fluid extraction device (no names) - honestly I think this thing is a piece of crap Laughing

, but the video shows the technique quite well...

That honeybee extractor is shit, really makes me want to patent my machine before I see it on the pages of pot magazines for 100's of bucks. Afoaf has been doing butane extractions for a long times, ever since it blew up about 2 years ago you see all this cannabis that looks good but doesn't get you high, (pretend-ica).

Ok, OK IndoleAmine now I get it.
Sometimes it's the simple shit that gets me. Certainly wouldn't know I have a lot of refrigeration experience, now would you. Propane and R-12 are very close temp/press wise.

...........it develops an enourmous pressure on its way down, and this causes it to travel downwards at the speed of 40cm/<1sec. Laughing ..........

actually 1.33ft/sec is not much velocity at all as house plumbing is maybe 6FPS or so.Somehow I just couldn't see a few feet of dry plant powder as enough to develop any back pressure with a low viscosity gas. Still though, liquid introduced directly and allowed to sit a while has got to be a lot more effective!

.........do it only outdoors, on windy days - and avoid sparks like the pest.... ......

Think my wife would care if it was hooked to the frig and used for another run? Nahh, better use the garage for the condensing unit. I think only SNG/LNG refineries use propane as refrigerant anymore.

So MoonRules.......... what do you say to the patent examiner when he asks you.....what the hell is this damn thing for,,,,,,,LOL

Isn't R-12 really really carcinogenic? Please bee carefull bio, your tweaking of plans might give you cancer. I think I would definetly go with a herbal oil extractor for patent rights. For isolating essential oils. Would that even work? Can you extract essential oils with propane/butane? hmmm.... That would be great if you could extract oil out of pepper for piperine isolation. Would cut down the huge amounts of pepper needed. I dunno i'm dumb, and this probally wouldn't work at all.

IndoleAmine · Dreamreader Deluxe

With solvent extraction, most surely yes (some piperine xtraction methods use a soxhlet solvent extraction, so supercritical fluid extraction will extract piperine too I would say).

However, the commercial essential oil of pepper (piper nigrum) is made via steam distillation and I don't know if this will contain any piperine at all.

bio · Working Bee

Most any essential oil which is not very polar should dissolve well in the lower alkanes. Enflurage (sp) is still used for more delicate type oils which tend to dissipate or decompose at steam temp, like orange blossom. This is where they soak the plant in warm lard or tallow.

Pentanes (Bp 30-50) or Hexanes would be the best choice for solvent extraction of non-polars because it's easier to handle and recover than a gas. Use EtOH (96% min) preferably absolute for polar compounds.

The steam distillation method is most often used however and is very easy but takes a long time and requires a lot of heat and condensing surface to proceed at any reasonable rate. This in simplist form is just boiling the plant with water and condensing the steam. Even slightly superheated steam is way more efficient especially for higher boiling oils.

..................Isn't R-12 really really carcinogenic?........

Not too sure on this. Supposedly CFC's are carcinogenic but you would have a hard time breathing the stuff as it has to be used in a closed system.

My idea here was to use an R-12 condensing unit for recovery of the propane as the physical properties are fairly close. R-11 (Bp 23deg) would be a good extraction solvent but is not at all selective and would dissolve damn near anything similar to chloroform which I suppose is carcinogenic too. As long as these types of chemicals ,benzene for example also, aren't breathed on a continuous low level a whiff once in a while isn't going to harm you. Most are simply uninformed as almost all who developed leukemia for example were in a production/manufacturing environment for years breathing the stuff everyday. It's a damn shame the chem companies jacked up the benzene price to ridiculous levels taking advantage of the scare tactics promulgated. I doubt any chemist (with common sense) is ever going to be harmed by benzene especially now that the exposure limits are known. Whether or not they are right is another question.

They have scared the young students to the point that they would be terrified to even open a bottle of NaCN. Hell, I had to put an add in the f........g newspaper to notify the community where a kilo of it was located.
Enough on this, it pisses me off, I could go on and on.

Just a point, but these butane or propane extractions are not supercritical; they are boiling solvent extractions. The supercritical pressure for butane is several hundred psi. A supercritical fluid is a superior extraction solvent but to make one takes a lot of engineering.

Edit:

Critical temperature (Celsius) and pressure (bar)

Butane 152 37.96
Propane 96.6 42.5

(You can't do this in a PVC drainpipe).

IndoleAmine · Dreamreader Deluxe

Oh - I just thought, since it happens above butane's bp and under pressure....

(works awesome anyway! And together with ISOing certain resinous extracts, aahh....)

Any input on the piperine idea? Else The_Moon will have to start experimenting I guess - you hear me?...

Here's some info for moonrules.

Seems solvent extraction is necessary but maybe you could get your hands on some of this "Pipersin" stuff. Propane would work of course but is unsuitable I think for the amount of plant matter extracted to get any reasonable amount of piperine. After you cleave the stuff maybe the left overs (cyclic amine side) could be converted to the methprylon. Although a direct cyclization or pyridine hydrogenation is probably much simpler. Just stumbled on it so thought you might like to know what the byproduct could be used for..

All I could find on "pipersin"but it may well be a synthetiik of some use and OTC as well. Know any butchers maybe?

Tried to put three molecular mages in but they always go to the bottom of the page. Maybe they are there.

“Pipersin.”

TM for a substitute for oleoresin of black pepper. Officially recognized by USDA Meat Inspection Division for use under its supervision.

Ullmans excerpt....................

Pepper oil and pepper oleoresin are obtained from the black pepper Piper nigrum L. (Piperaceae). Pepper oil is produced by steam distillation of whole or crushed fruits. The oil is an almost colorless to bluish-green liquid with a characteristic odor, reminiscent of pepper, but without the pungency of the spice.

d2200 0.870 – 0.890; [a] D20 – 16 ° to + 4 °; solubility: 1 vol in 3 vol of 95 % ethanol; ester number: max. 11 .

The oil contains mainly monoterpene hydrocarbons (ca. 80 %), its main constituent being sabinene [3387-41-5] (20 – 25 %).

[img]

Pepper oleoresin is produced by solvent extraction and, unlike the oil, contains the principal pungent compound, piperine [94-62-2] , along with some essential oil.

[/img]

Pepper products are used for flavoring foods; pepper oil is also employed to a small extent in perfume compositions.

..................methylprylon.

[img]

(3,3-diethyl-5-methyl-2,4-piperidinedione).
CAS: 125-64-4.
C5NH4(O)2(C2H5)2(CH3).
Properties: Nearly white, crystalline powder; slight characteristic odor; bitter taste. Melting range 74–77C. Soluble in water; very soluble in alcohol, chloroform, ether, and benzene.
Grade: NF.
Hazard: Abuse may cause addiction.
Use: Medicine (sedative, hypnotic).

Could try using CO2 instead of propane, CO2 makes a very nice non-polar solvent and doesn't explode like propane. But hehe nice job.
