New extraction technique? Rosin tech?

[heady blunts]

i usually do an ethanol wash.

it's kinda expensive but i feel confident i get a complete extraction.

the hash i get from that goes into my edibles and topicals---products that won't suffer from the diminished terpene levels.

edit: that's cut up rosin wafers in a half gallon mason jar. i don't worry about quick wash or keeping anything low temp for these extractions. i fill with 190 proof grain alcohol to cover the material, shake it a few times, then strain into another mason jar. i then carefully evaporate the ethanol (fire safety is important! the vapors can easily ignite if i act like an idiot). when i'm left with my concentrate, i add my desired amount of carrier oil (ususally coconut, it's very versatile), and decarboxylate. for decarbing i follow gray wolf's method and heat in an oil bath at 250*F until the bubbles change form, indicating all the carboxyl groups have been separated.

i use the resulting activated infused coconut oil make most of my products.

Wow looks like the rebel insignia from star wars. Thats effin sweet!

Already invented paperless, just didn't realize there were so many people willing to throw good money after something that can get knocked together for under 100 bucks..

Especially with these longer press times people are using..

So were you just yanking our chains or??? We would love to hear more if you got time.

Been pressing the kief i made, getting around 30% yield at 200* for 1 min. Slightly less yield than the hair iron but the cooler temps have way more flavor. Had some help today so we pressed out 70 grams of rosin...

 

[hash head]

can compressed air alone be used as a solvent? say put into a cls for example?

Is anyone using a lab press? Some of them have adjustable heated platens.

I was thinking of buying a used one similar to this. I believe it has two sets of 12" x 12" plates with 30 tons of pressure. Any thoughts or suggstions?

 

[50YardLine]

lol, that would do the trick.

It's overkill, and will take up a ton of room. However, you could squish a car with that thing.

Operates similar to the one I am putting together. I don't see a reason just from the picture it wouldn't work very well.

Edit: the only problem I see is the oil has nowhere to run off, without continuing to heat. I overcame this with my first press with buying a smaller steal plate, 1/4"x5"x5", and that lifted the material enough where the oil ran off and had room to cool. Good luck.

Pressed some bubble at around 220 last night

old squished rosin chips cut up a bit and thrown into a lb of butter. I believe it was around 62grams of rosin chips

Been squishing Jack Herrer the last couple days. Above average yields, and some of the best tasting oil I have made myself. If you can get your hands on some, I suggest squishing it.

I agree. I grew king klones black jack last year and it came out awesome. Very high yield and nice light blonde rosin. It comes out very runny and difficult to collect but the flavor is incredible. I definitely recommend it.

 

[overgrowit]

50YardLine, I was thinking it was overkill also, but after looking at the math it might not be enough psi.
12" x 12" plate is 144 square inch. 30 tons(60,000lbs) divided by 144 = 416.6 psi

Maybe a smaller plate like you said, would allow for more psi and a place for the oil to go.
I just don't know if the original heated platens would transfer the heat to smaller added on plates.


TheWhitLotus, looks tasty! What kind of press you using?

 

[thewhitelotus]

thank ya! im using a 6ton hydraulic press and manually heating plates. Been trying to buy heated plates but having difficulty finding anyone with a quick turn around! this damn cash is burning a hole in my pocket......need heated plates!!!!

 

[blastfrompast]

there are platen blue prints out there now, I believe the last quote to have a machine shop make them was $150...

Or go to a steel shop, and buy some raw materials and make ur own with a bit of ingenuity..and ptc heaters

 

[Ringodoggie]

Since we are talking about rosin in this thread, I have a question about rosin.

Why are we not using a soldering iron for dabbing rosin? I have a beautiful Weller adjustable station that seems perfect for this task. I'm not sure what the tips are made from but perhaps a custom tip/dish that fits onto a standard soldering iron.

?????? Is there a reason why I have not heard of this before? It seems perfect.

So about that paperless collection you say you already invented? Been dying to hear more please.

OK, sorry about the slightly off-topic question above but I did a little shopping so I'll share what I bought.

I have been using 6" x 6" square platens and simply putting the package close enough to the edge so that the rosin could flow freely out of the heating zone while still not allowing the package material itself squeeze out. This was fine while I was experimenting with different packages but, at this point, the round puck seems to be working well for me so I am going to keep in that direction.

With that in mind, I saw a set of commercial platens that looked nice. They were round and just slightly larger than the chip that remains after pressing one of my pucks. That seemed logical so I bought these...

3" in diameter and 2" thick. $15 for top and bottom platens.

To heat them, I am trying a couple things. First is the tried and true cartridge heater. We have already discussed how the specs require that the tolerances to be very tight for optimum performance but I will hand drill it and if the cartridge heaters get hot and heat the aluminum plate, then they work for their intended purpose. For under $10 each, I bought an assortment of flavors. Progress, not perfection.

The second thing I am trying for heating is a band heater. This is the first I have seen of these and I have not heard anyone else mention them so I don't know how well they work but.... we will find out.

Unfortunately, this stuff is direct from China so it will be a few weeks before experiments can begin.

What I am wondering is if I will actually get more yield or a different quality by allowing the rosin to escape from all the way around, rather than pushing it all one direction as I am doing now.

 

[Hashmasta-Kut]

What you could be hoping for is both being higher.

id assume whatever method gets the rosin away from the heat source as quick as possible would improve quality

Will ask again has anyone tried extracting through a tube with compressed air? I ask because there was talk of making rosin without heat or a press and this is what I guessed people might be doing.. Can compressed air (liquid nitrogen and oxygen) be used as a solvent? Can a large air compressor be used to extract oils by filling a tube with liquid air and releasing through a filter similar to the bho process?

this came up in discussion before and i recall that the conclusion was it wasn't possible due to oxygen inability to dissolve THC.
