Rosin Technique....Easy DIY Solventless

nopartofme

Over the falls, in a barrel
So I took a break from pressing for a bit, since I'd been pressing like a maniac for a few days there. Yesterday I did something a little different. Rather than pressing and dabbing one at a time, I pressed out about 1.5 grams of herb in four pucks and loaded up all the rosin into my V2 S3 oil cartridge before heading out for the night.

Anybody who follows the V2 thread knows that I've soured on the S3 overall, but the oil cartridge is the best cart of the three IMO (doesn't taste very good though). It felt wrong putting all those terps in a poor tasting vape. But I've gotta say, the pressing took me all of ten minutes tops and I had enough rosin in my pen to last me all night. Nice!

I've been thinking about optimizing puck size, meaning the diameter of the herb post-pressing. This is tricky because I figure it depends on the amount of pressure available. But, I'm thinking minimizing puck size might be a good aim for folks who are using a hair straightener, and/or don't have a pollen press or something like it, and/or can't maximize pressure for one reason or another? My thought is that a larger puck may end up soaking up its own rosin or so, if the pressure is not great enough to match.

I figure that is where pre-pressing your nugs comes in handy: higher density should mean smaller pucks? Which should mean that re-absorption and incomplete extraction should be minimized. Combined with the theory of larger (diameter) pucks needing more pressure, it's as if you can mathematically add pressure to the equation before-hand with a polin press in order to get away with less pressure during extraction. :science:

This is all theoretical, as I don't have a means of mechanically pre-pressing my flowers yet so I can't test it out. It would be interesting to do an experiment something like:

A) Press 1g nug in hair straightener
B) Break up 1g nug into quarters or thirds and press each fraction individually in hair straightener
C) Pre-press 1g nug into a disc, then press in the hair straightener

Then compare the yields, of course. While C should have the clear advantage over A, I'm curious how much better B might also be versus A, and how close it might come to C?

"Hashmasta-Kut" posted this on another forum I visit sometimes and it may answer some of your questions:

Hashmasta-Kut said:
got some numbers:

1.00 grams starting material, quite damp

0.16 grams yielded on first press in 5 tiny pressed balls in a hair press at 270 for 7 seconds or so.

.74 grams bud weight at that point, showing 0.1 grams of moisture escaped as steam. giving initial bud weight at .90 grams

second press gave approx. 0.02 grams. bud weight dropped to 0.70 shows 0.02 more grams of moisture escaped as steam, gives final bud weight calculation sans moisture at 0.88 grams, with 0.18 grams of extract yielded, gives 20.45% yield. or if you include the moisture it was 18%. this was with an OG cross, it is Highend(blueberryxrene)x ogkushS1 bred in Israel.
__________________

So i have done my 1 gram test 4 times now with the same product and got the exact same results every time, well within i would say +- 0.01 grams. and the last time i did the test i only broke the gram up into 3 pieces roughly 0.33 each, and it yielded exactly the same as 5 pieces at roughly 0.20 each. i got 0.16 on first press 4 times in a row now, and around 0.01 to 0.02 on second press, which is beginning to look like a waste of time.

Once people figure out how to extract on a massive scale efficiently.
I have seen so many new ideas of heated presses in this last week alone I have no doubts! I feel like I am in a race against time to finish mine. I figured out my scraper attachment design today, I just need some shop time to build it now. The last hurdle is how to heat? Piece of cake!

There are so many posts about how much more effective rosin is as a medication compared to bho and how much cleaner the nail stays with rosin over BHO. Add in the higher CBD's and flavors and bye bye BHO!

Edit: just from one small FB post alone.
its hard to beat the buzz from well made rosin.=== find rosin provides me with a more full sprectrum high that i dont get from from the butane exracts.===rosin has a way superior buzz then bho nuff said===Full spectrum ====Bho is garbage nothin medicates me like the rosin

You got me. Don't try and press your buds between the hot asphalt and a drum roller :D

My street is being repaved next week. I wonder if the workers would let me lay out whole rolls of parchment on the hot asphalt. We could just follow the steamroller down the block collecting rosin in its wake. The whole neighborhood could bring out their stashes for rosining! :freak:

That sounds like the beginnings of a new holiday: Rosining Day.
Kinda has a nice ring to it. Happy Rosining Day.
I can see it now...

Think they mean that they got that 96g slab then put did a butane run of the crushed chunks and got 56g of bho. Kind of an impressive slab, but obviously not super effective if you're getting ~60% extra return still left in the remains.

Just a quick update on this one. Either he has gotten better or there was a typo or somethings going on...
Larry said:
As for my returns, well my larry bubba gets about 18-20% rosin or bho..my sweetskunk gets about 15-18% but my cali big bud gets about 12% ...i have rerun all my pressed nugs thru closed loop system and always got another 5-8% additional concentrates.

And this was interesting.
Larry said:
1 ton over 1"x1" is monsterious psi but very insignificant spread over 1'x1' area...I.don't use the whole 5 tons..i'm more interested in sq/Inch area and the psi exerted over that area..

Any math guys know how to convert say 5 tons of force? spread out over 576 square inches converted to pounds per square inches? I'm not sure its even possable from the google search info I found?

Not sure if long or short tons, or what measurement is even being used as "tons" by the press maker? I suck at math!

2000 pounds per ton =10,000 lbs
10,000lbs ÷ 576in = 17.36 lbs/sq.in. [pounds per square inch]


I think, someone check my math. :rolleyes:

be that the case im using at max about 8lbs per sq inch .... ironicly having a large dude standing on a tiny plate would equal ruffly the same pressure as a large press on a 2ftx2ft plate.

Thank you!..So if there is six(2x3) square inches on a hair press and say we put most of our weight on it, say 150 lbs, thats roughly 25 lbs per square inch. that means were getting more pressure with the hair press than a 5 ton press with 24x24" plates. hmm

edit:
Don't beat yourself up over yields.
He went from pressing only 40% rosin out of the material to getting 92-95% of it out. Thats either a huge improvment or an error?

Edit #2: I got some "test" nugs being delivered as I type this. Soon I will be rolling some rosin in a heated roller press for science!

error I think... I find it difficult that by weight he was getting that much from dry cured material unless ... he was starting with wet weight. or adding something.... like distilled water to accelerate the process. I mean I could see getting that high if he was going from a wet weight cause then he is also getting all the hydrosols and waxes from the plant as well... well... maybe we need to do some general math in here to make sure we all actually know how to calculate percentages
:rofl:

this is the point where the mind meets the ego. where is the error? in calculation or belief?

edit: ive been playing with much lower temps and man is that where the yield is at. 275 is todays lucky number I will show that off later... this is some of the last of the purps and I managed to get some purple rosin out of one of the buds!... photos is shit but there is an obvious different in color... all of it is the same strain and it is devine! the rosin thats purple is nothing like the smell or vape of it... its as if in that one press I managed to squeeze out the last bit of true floral aroma that was left and it is... ugh... devine.

Maybe we are confusing yield % with total extraction %. A few weeks back he ran 1.5lbs (680g) and got back 96g (total rosin extraction) or 7% (edit 14.12%) yeild? leaving 56g recovered from butane closed loop. ya math is wrong somewhere..
Now He says he getting whatever 12%-20% yeild at almost 95% total rosin extraction. leaving only 5-8% left for butane closed loop extraction. Pretty impressive if it's not an error.

Edit: I need math class. My bad

"i have rerun all my pressed nugs thru closed loop system and always got another 5-8% additional concentrates." Seems like if the decimal was off on the 56g bho after rosin, that would be right in the 5-8% range off 96g...

edit: yea, so 95% of the yield was rosin, I guess...

I think you figured it out. ..Thanks.

So my first attempt at rolling rosin in my press was an utter failure! Not as easy as I thought it was going to be. I rigged up 2 halogen lights behind each roller and warmed it up for 20 mins or so, checking the temp with a laser temp gun every few minutes. At what was reading around 200f I balled up a bud and forced it into the rollers. Instanly I heard the death sizzle and smelled my rosin vaporizing, WAY TOO HOT!!! The bud was stuck to each roller and i watched whatever oil quickly dissapear.

Question? How can I accuratly measure the temp of something that is shiney without painting it black or using a melt stick? any thoughts?

I kinda thought the heating part was going to be the "piece of cace" part. lmao..

What about going old school and just holding a meat thermometer to the surface? Good old touching stuff!
Hmmm. Old School..lol I still feel I am going to have serious issues with the bud sticking to the rollers but maybe at lower temp it wont. less pressure also. Trial and error!

I'm rooting for you, I hope rollertek is the next DVD, not Betamax lol. Hopefully once you get good extraction down the buds will be dry enough to fall off? Maybe some kind of rake setup with tines to flick them off if not...
Thank you sir!

@darkrom The meat thermometer seemed to get me in the ball park. It only reads to 220f but i'm guessing I was at least 260f on the dial. I only ran one .3 bud and was running out of time for the day and here is the result on the roller. It does look better in person than this pic. This was also less pressure as I was pulverizing them from too much pressure. No bud sticking issues this round. There is hope!!!.

Edit: Not sure I will invest too much more time in these rollers as they are just steel rollers and the moisture is already giving me rust issues. Heated teflon rollers and probably some UHMW or Delrin scrapers are in my future I think.

Edit2: Bamm, Teflon heat shrink roller covers!! This is like a roller coaster of emotions... LMAO

someones got his thinking cap on!!! I like the shrink on covers. once you have your machine tuned that bud should just fall off every time cause its dry and oil free. ive only been getting one good compression out of each of my pucks cause im getting... lol ... 75% of all the rosin in the flower [im not talking specific strain yield]

but I know haters still exsist...

dabs smashed! lavender strain! totally uncollected

I apologize if you thought I was hating?. Far from it! I seriously struggle with math at times and I just wanted to clear things up and get us/me on the same page. You kick ass at this.

nope;) wasnt referencing you as a hater at all! I actually love the direction you have gone... I originally thought that a roller press would work but it was outside my realm of diy. ive gone with a press type but the commercial applications for what you have come up with are very high I think...

I reported my own psi wrong yesterday actually...

so I was calcuting max output of weight being 300lbs and the plates are in fact 6x6in but heres what I didnt factor... the pressure isnt over the 6in area cause im not running but 1 puck at a time with a starting diameter of about 1/2" and a final of a little more than an inch... so its more like im using a full 300lbs max force so yea...

I noticed your temps and actually applied it to my setup as well [well im at 250 and its produces a much much more terp filled rosin! omg!

I remember back when I first started making bho everyone was hung on yield too... but then we all collectively realized that percentages make little difference when quality is higher!

:love:I love rosin tech:love:
