New extraction technique? Rosin tech?

[heady blunts]

i wonder if the clamps add pressure arithmetically like that. if so sweet!

the smaller 5x5 insert is money tho. that's definitely important. so let's say you're getting 1200lbs of force divided by 25 sq in then we're talking around 48 psi. who knows how accurate that is to your actual situation, but for the sake of the discussion, we can assume you're safely below the numbers being thrown around by sunfire and strait and rufiocraft (1000--2000psi ideal range).

i wish i've had an ounce of bubble to press! i work only with my own material and i've found the most efficient and cost effective way for me to make rosin is to squish our trim. i made myself some bubble a few months ago and squished all the non-full-melt. that makes up the majority of my hash rosin experience. the rest is from grinder keif and finger hash lol.

Yea, 48 psi.

Those other guys claim 1000-2000psi. However, is that the total pressure the press does? Or what the press actually applies per square inch?

I could say my press applies 1200lb per sq inch, but then that is distributed over the 5x5 plate, which really makes the pressure per inch 48.

I am guessing they are around 48 psi also, otherwise I would think bubble would be squirting out the sides....... Anybody know the actual PSI?

been out of the extraction game for a bit, absolutely fascinating what has evolved past few years.

gave a squishing a go last night with a hair straightener and hand clamps, amazing results and decent yield!

this whole time....all we had to do was squish the damn thing!

exciting stuff!

those numbers are real. like i said i use a 4 ton press.

1 ton = 2000 lbs

4 tons = 8000 lbs (force)

PSI (pounds per square inch) is based on the size of the packet force is being exerted upon, rather than the plates themselves. ideally your packet size (after squishing) is just a hair less than exactly the size of your plates.

i ususally make my packets 2 or 2.5 grams, that works best with my press ime. the 2 gram packet squishes out to a 2"x2" square.

2"x2"=4 square inches

8000lbs of force / 4 square inches = 2000 psi

when i do my 2.5 gram packets they are more like 2"x2.5" after squishing, so:

2x2.5= 5 sq in

8000/5= 1600 psi

my press is a little clumsy, so i rarely try to fit a full 3 gram packet in there, which if perfectly placed, should press out to 2"x3".

2x3= 6 sq in

8000/6= 1333 psi

all of those work great for trim. i get an average of 15% return on one press, then i ethanol wash the chips after i accumulate a half gallon mason jar full to extract any oil left behind.

i could further increase my efficiency by cold pressing the material before i put it in the rosin press. sunfire says he's settled on 1g per square inch of material he can pack before he gets blow outs, vs. my 0.5g/sqin limit i'm hitting with hand packing paper tea bags.

the guys doing large amounts per press and getting great yields of excellent quality rosin are staying within that 1k-2k psi range and scaling up the force of their presses to accommodate the size plates they want to use (which determines how much material per squish they can press). seems from their reports that over 2000psi you start to get declining returns. sunfire just posted a great theory about why this occurs on his IG. collapsing passageways to paraphrase.

so much of the efficiency and end quality are dependent on how i prepare the packets beforehand IME.

Nice! That is serious pressure. I would love to press some flowers with that.

My shirt press for sure leaves flowers with thc. I can get a solid three presses, and get a 8-10% return. However that is with GSC that tests around 25%+.

No doubt, your press would do a much better job on flowers. Really want to try a press like yours someday soon.

 

[Hashmasta-Kut]

If you have a system that can go to huge pressure, and has an area for the extract to runoff or collect outside the press area, I believe incrementally greater pressure would be great up to quite a high pressure, that way the passageways as sunfire put it wont be collapsed until its too late to trap oils. Slowly incremental pressure.

Just got a set of Medisun dies in. Will report back soon. My friend brought some over a couple weeks back and it was fantastic results, much better than even my hair iron. The extension bar really seemed to help too for the leverage.

I am new to the rosin game and recently purchased rosin tech eat press. I am interested to know what size pouches people are using.

 

[zootcity]

Where could i purchase some of those screens?

 

[50YardLine]

fresh headies has rosin bags in stock

Wow, and I thought dealing drugs was a high margin. I guess drug accessories just topped the charts. LMAO

Here guys... http://www.ebay.com/itm/10-yards-11...956450?hash=item46153be0e2:g:V8IAAMXQatBSb-TH

Has anyone tried this stuff? I have a roll that I use for sifting so I'll let you know but if you take this roll for under $50 and cut it into 3.5" x 5" and fold them over and stitch them and sell them at 10 for $25 and you'll turn that $50 investment into $1850.00. Why try to make the money on the cannabis... catch the wave (or should I say, ripples). LOL I love capitalism. LMAO

I have not pressed much hash or dry sift and I only tried screens a couple times and none of it worked out well for me. I'm sure it was user error but if one of you guru's who know how to use the screen properly tried this commercial silkscreen mesh (and it worked), it sure would save you a lot of money on bags and stuff.

Just tossing it out.

I use the yellow 220, the white is heavier material and holds on to more rosin. I use the white on my tumbler and made up screes for sifting. I refuse to pay those kind of prices for Rosin bags...

 

[50YardLine]

Drop in the bucket when doing bulk.

However I agree you guys, I am asking my brothers girl to sow me up a couple thousand. You can buy silk screen, which has different measurements for microns, and sow and cut them yourself.

I find the 32u best for bubble

90-220 is best for trim.

 

[EastCoast710]

anyone using the 250$ unit from rosin tech? is it worth buying?

 

[Babbabud]

yea you get more yield with bigger mesh because you are letting through more impurities imho..... and im pressing mainly keif but i see lots of ppl squishing bubble hash ... so what happens when you squish the 45 through a 220 screen ... seems like you might as well not bother using one. Ive been using the 25u either in the cloth or bags to get the best filtering i can ... im looking for oil not slurry . Most of what i squish comes from the 61 lpi screen ... but i have squished some bubble .

rufiocraft just posted a pic of a nice squish of 2.5 grams of flower at 220f and 3800psi.

i asked about the diminishing returns number and he said it's more like 4k in his experience.

 

[heady blunts]

filter material can be folded around the pressing material like a little gift, no pouch necessary.

even easier if you cold press your material first.

 

[Babbabud]

ive reused my squishing pouches prolly ten times each ... still in perfect condition

 

[GET MO]

anyone went with a t-shirt press? hows that work? Is it enough pressure? if not any way to modify it to add pressure?
