Roji with the hash church shout out! 2nd place with the rosin tech, congrats bro!

I have not seen much of the Rosin in person, but has anyone such as Roji who has done this tech in there free time run any quantitative tests to find out a real percentage of adulterants in Rosin? Obviously this is a technique and depending on your skill I have seen product ranging from that massive, pretty slab a few posts back to somewhat less impressive... Has anyone winterized some of this stuff just for curiosities sake to see if any fats/lipids get picked up in the process? I realize that no solvent means that most people are all in, but from a medical perspective I have met folks who smoke decarbed, winterized oil for the ease on there lungs and I wonder where this process falls on that spectrum. After all, even terpines are added expectorants into the mix and are not ALWAYS a good thing depending on your consumer.

from what i have experienced so far its always been very smooth. I think its probably as smooth as a winterized bho, but with more flavor/ terpenes by far.

So the past week I've made a few observations. The less press time the buds get the more of a shatter you are going to get. It also seems to retain more terps. For me and my press Im seeing 350f for 5 seconds as the sweet spot for shatter. Soilgrown uses 325f for 2 seconds. The differences may be strain or batch specific. Now saying that, I have also done some 30 second presses @ 350f that spewed huge oil blobs that were a little darker and had a little less odor but were still very strong full melt dabs. This routine would be good for patients just trying to harvest oil for medicine as opposed to rec dabs. There have been tests done on 30 second presses that showed relatively low decarb, but having lower terps.
I can see production pressing as having grades of heat/time exposure. 3 second, 5 second, 15 and 30, potentially.

Below are pictures of a 1 gram pellet I made and pressed. It shows the first 5 second press, the subsequent 10 second press and a final 15 second press. The pellet being exposed to a total of 30 seconds of pressure. Total yield was approx 15%. You will notice I have placed a tri-clamp end cap on my base. This is for maximizing the pressure applied to the bud pellet. I'm pretty much breaking the parchment now due to the extreme pressure.

I'm curious how that guy with the big golden slab got all the spent material off of it? Is it as easy as freeze and scrape? Roji how are you collecting it together? Freeze, ruffle parchment into a pile and heat, press/roll into those little patties?

I'm all for it if we can make a patty like in that pic in one press! But yeah it'd be nice to regain my investment on the cls but for people like me that might take years lmfao!

I'll definetly sit and watch the R&D developed and maybe I'll have a good idea or two to contribute. Good job roji, if this blows up we all might remember your name when we're old and long forgotten.

Admittedly I could have spent more time cleaning it up more before collecting. Buuuuut here's the new cool. Pressing the oil through a 25mu bubble bag screen wrapped in parchment/ptfe...

Oh good! I hate the 25 micron bag. It's fucken pointless, only gathers trichrome stalks and impedes your drainage immensely. Well sweet I got a few of those from 20 gallon bags, they about 18 inches wide I imagine.

Ok so just figure me how to 18 inch wide presses with the best efficiency, then figure out how this will work great with trim instead of flower, and I'll come bring you some grant money and a big American hug! I got a friend in calgary, sounds like a fun road trip?!?!? Hit eugene, then portland, then seattle, then vancouver, and round off the extraction tour at my friends brewery in calgary!!!

Hell ya, c'mon up .
The pressed weed coin deal in pic one and 2 will be an avenue to using viable trim, I'm sure of it. I'm also sure there is fancy heat presses with all the bells and whistles to make this tech more efficient. Something like THIS

i still think the cylindrical plunger is the best bet. then you prevent the puck of weed from spreading, and all the oil can leach out easily. also could put a fair bit into a strong tube setup to press at once i bet.
