New extraction technique? Rosin tech?

[redlaser]

I get less than 10% (more like 5%) from pressing flowers. If you're getting 20 - 25% pressing flowers then I am doing something wrong.

Usually I don't weigh it but I was squishing some high yielding cheesequake and from a gram got .2 grams back. This is using a cold pressed puck and the pot is not damp but almost needs to be dried out more because it spreads out a lot during pressing. when it's more dry on other strains like c99, visually the yield looks to be half of that, although it's lighter colored and I haven't actually weighed that yet. 90% of what I've squished has been Jack the Ripper and Cheesquake, both are equally good yielding

I get 15% or so with one strain, and a consistent accurately weighed 21% with another, an ogkush cross. I have gotten 25% with a third type, a stardawg cross. And this is with the vice grip c clamp and hair press tech. I did some yield tests the other day and can get 21% with pucks as large as 1.4 grams, repeatedly. i tried a couple smaller pucks around .9 grams and got the exact same yield.

 

[heady blunts]

that's solid data thanks HMK!

are you pressing the material more than once or are those numbers from single squishes?

 

[Hashmasta-Kut]

single squish numbers. second squish would give at most 3% more.

Cool, thanks. I never press twice. I tried it a couple times but I am just bagging the chips after one press for now.

At 5% I must be doing something wrong.

I am going to run a test using my hair straightener and my 1 ton arbor press. I did a few presses like that and I really liked the "feel" you have vs the A-Frame 6 ton press I usually use.

If I am still getting these low yields with both presses, I might be too moist or too dry. I keep all my pot in Boveda jars at 64 to 69% RH.

Or, my method of pressing pucks needs revised.

Or, my pot is just shitty. LMAO

Thanks again for all in input, gang.

try compressing your material more before putting it in the heated press.

the evenness and density of my pre-press prep makes a big diff in my efficiency i've noticed---evenly packed and tightly compressed material gives me the best yields per gram and the wafers come out nice and dry, not sticky at all.

i think oil gets trapped in the relatively large spaces between the material and does not have reason to keep on movin. then it just cooks there and makes the surrounding material a sticky mess. same thing happens if i wrap my filter material incorrectly, i end up with the sticky mess on the edges trapped in the excess material.

You know what man, you hit the nail on the head! I always pre-press, but for some reason I didn't for a couple nugs, and didn't even give it a second thought. Those were the only 2 nugs that night that came out that way and the only 2 I didn't pre-press. I agree with everything you said.

It all depends on the starting strain and the pressure and the heat. With a hair straightener you should be able to get around 10% from most any strain, but even with my pneumatic press and plates, sometimes I only get 7-10%. If that happens, that strain never gets put back into rotation

Some strains just don't press well...but that does not mean they are not worth keeping! I have a strain that presses VERY well, but it is not a heavy yielding plant. I have a couple strains that yield extremely well, look and taste phenomenal....but they don't Squish well. If you are only growing your buds to squish them, then I get your point. But just because a strain doesnt press well, doesn't mean it is not worthy of keeping. Some strains test low in THC, but the effects could be better than a strain that tests higher. I squish flowers daily, but I am not giving up quality strains that yield way more flower. I just won't waste my time Squishing them. To each is own.

I have a strain thats low yield, my lady smokes most of it but i press the odd bud for the nice flavor.

But, if you can get something that is super strong AND yields 25%, its super great

Hi all ,

Hi all ,

Greetings ,
I have been lurking on this thread for a bit and have been experimenting with pressing kief and flowers. I started with a hair iron - surprise! , but now a friend and I have put together a 6 ton press and are using it. For now we heat the platens with a torch to desired temp and we can get a few presses before it needs t be reheated.

I am posting because i have a few questions and was hoping I might find a bit of help to improve my tech.
1st has anyone used long skinny packets to press ? If so , what did you use to shape or press your material 1st. I think the ideal shape might be a long skinny rectangle as opposed to a circle - any ideas on this ?
I also am curious if anyone has a good plan for a DIY kief tumbler that can handle a 1lb or so at a time ? I have access to a good amount of trim and it seems making kief to press is the answer . As far as that goes what size screen would you suggest to use for making the kief I plan on pressing ?
Lastly where is the best place to buy screen or filter material for pressing? What king of screen material is working best for kief? I kept having blowouts using some unbleached coffee filters.

I sure appreciate any feedback and thank all of the people who have posted such great info here . I do not like solvent extracts but love this rosin so I really appreciate your help.

Thanks and sorry for such a long post

In my opinion for shape and size in our still primitive imo flattening tech to extract, circular is better for smaller squishes, say up to a gram maybe, but when you want to press more at once, a snake or rectangle as you say is most likely better for ease of complete leach. When i do 1.5 gram presses i roll it into a super dense short snake, about 3 times as long as it is thick.

Thanks for your reply Hashmasta ~

Thanks for your reply Hashmasta ~

I just got back from a friends house where my squish station is located. We have a 6 ton H.F. press and 2 steel platens we heat w a torch to between 180-200 F. We used coffee filters first but felt they soaked up too much rosin and blow out too easy so we switched to folding fine SS screen into packets. It works much better and doesn't blow out as easy. I had some 4 year old trim stashed in the frig and i made some dry ice kief an d pressed it and got 30% return on my squishes. Given is was so old an all it seemed pretty good and the kief was pretty coarse. I will try to post some pics.
thanks for all the inspiration.

BTW - we were gettiing a lot of shatter so my buddy had a idea to pull out an old infra red heat lamp he had an put the parch w rosin under it for a few seconds to warm it up . Sure enough it made the material pliable again and was then easy to collect. I also used it to hand compress the kief. I set a parchment paper with kief under it for 30 secs then rolled the kief in the parchment like a doobie and got a beautiful snake that was easy to package in a filter. The light heat made the kief easy to bond together and was a great trick !

Seems you guys are really getting into this whole rosin thing. Might try it but love me some pho and bho extracts a lot so not sure which way to turn at this point. Guess a wally world hair straightener and a clamp are easier and less expensive than a new cls.....how is the rosin itself vs dabs of bho or propane??

I really like this propane extract I just sampled amazing terps and its edible as well...

 

[the Falcon]

Yes!!

Yes!!

I am really getting into this ... I am new on this forum but have been active with pot for 30+ years. I believe this rosin is better than any other extract i have had. For one it is not harsh - bho and other solvent extracts make me feel like i got punched in the chest - this is smooth. Plus I for one don't like to use any petrochemicals to prepare something I am going to vape or smoke - just my preference - give it a whirl , you might be surprised!

soapstone platelets?

soapstone platelets?

Howdy, I've enjoyed following this thread and wondering if steatite (soapstone) has been tried as a possible platelet material? Don't see it mentioned anywhere. Soapstone has an excellent temperature retention characteristic. Thanks.

Does it handle high pressure well though, around 2,000-4,000 psi?

Good question. The property that enables soapstone to retain a steady thermal signature for upwards of 30 minutes, or so, is it's relatively high density. That same property might be attributable for it's innate ability to resist compacting/crumbling due to high pressure. As to the upper limits of soapstone's ability to handle higher pressures, I cannot say. Are you suggesting, however, that pressures in the range of 2,000-4,000 psi are necessarily required to extract rosin? How are you measuring psi values?

 

[Ringodoggie]

I think soapstone is a soft rock but would still take 10,000 -12,000 psi to crush
