How are you pressing the trim , are you tumbling or dry icing first? Please share your technique on how you get those results!

happy to share! pressing trim is just that! squooshing my trim! i've squished sift and bubble but i'd call the result of either of those products hash rosin.

did you get a chance to watch the videos in this post? let me know what part you'd like to discuss!

i have a couple on IG showing how i do it. @sunfire_ranch coined the term burrito tech.

this is how i used to do it for my early model HMK press (quick clamp).

here's how i do it with t-sac brand paper tea bags and fold for my shop press (2"x3" steel bricks).

i did that envelope a bit too tight you can see it blows out a little. i recommend leaving a 1/4" of space for expansion.

We know from experimentation that moisture does affect yield, so work is definitely being done by water vapor, and the pressure and flow it creates.
It's an attractive hypothesis. But just observing a correlation between moisture and yield does not reveal a mechanism of action in and of itself. To state that work is definitely being done is a tremendous leap that is not supported by this data.

Water does not have to be boiling to create vapor pressure. Water will evaporate at room temperature, and although boiling water vaporizes faster, it's still far from an instantaneous process.

The chart below shows how vapor pressure ramps up with temperature. It shows that 80c water produces about half as much vapor pressure as boiling water, and should vaporize roughly half as quickly.

80c is 176f, and when we press at that temperature, the moisture content will work just the same as it does at higher temperatures, just half as quickly. This is why press times must be increased when using lower temperatures.

Do you have a science background? I ask because this entire statement is pretty misleading. This graph does not show time relationships - it shows boiling points under vacuum. Your statement that it would take twice as long to evaporate the same volume is demonstrably incorrect. A cup of coffee is about 80C. Put a cup of coffee next to a boiling pot (same volume of water). Time how long it takes the water to boil off. Now wait that exact same amount of time staring at the coffee. Do you really think the coffee would have evaporated completely before time is up??? This is not a linear relationship in time. The difference in vapor formation at 80C is orders of magnitude lower than at 100C. And this is an open system, so I don't see vapor pressure as terribly relevant.

I really want to know what's happening here. I would love the steam theory to be correct. I just haven't seen any convincing evidence for it. And I think there is some convincing evidence against it. I know some here really like the theory, so I'm going to go ahead and let this go for now.

On another topic, I love your vacuum extraction/condensation idea. A lot of what you claim here would be true in an evacuated environment. Are you going to build it?

If I have been in error then I apologize, but I have not meant to be misleading. I did not intend to give the impression that the graph I posted showed any data regarding time, I only wanted to illustrate the relationship between water temperature and vapor pressure.

That said, I will stand by my comments for now. I believe if you had 2 containers side by side- one kept at 80c and one kept at 100c, the cooler water would evaporate at 1/2 or 1/3 the rate of the hotter water. A cup of coffee doesn't evaporate quickly because it's losing energy as soon as it's poured- there is no heat being added to the cup, so the coffee quickly cools to the point where evaporation is negligible.

As far as vapor pressure being relevant, I believe it is. There's a reason that people pressing quantity are using burrito and enchilada techs. These techniques are simple ways of optimizing and directing the gas/liquid flow. The bubbles that come out with the liquid during a press are a mixture of vaporized water and terpenes, and generally dissipate to the atmosphere rather than being re-condensed. These vapors act as a propellant, pushing the liquids away to where they can be readily collected.

If you really want to know the evaporation rate of water in a low temperature rosin press (or, in other words, to test the "steam theory") there is a simple way to find out. Dry a cotton ball in an oven at 220, then weigh it. Moisturize it using a controlled humidity environment (if possible), then weigh it again. Press it like you would low-temp rosin, at 180f. After the press, weigh the cotton a final time and check to see if any water has condensed on the parchment. Calculate total percentage of moisture mass lost, making sure to note the temperature, press time, total starting moisture, and pressure, if known. Then report back, because I'd like to know what you find out.

I'm glad you like my vacuum press idea. I plan to build a working unit, but my resources are limited so it will take time.

Can any one point me in the right direction of good quality presses I'd prefer pneumatic, how would this do as a vacuumed heat press? Its a brand call freesub

Here's a video of it in action, looks like it's vacuum or pressing pressure, not both. For normal pressing, it would depend on how much force it delivers. Definitely looks cool and compact though.

collective knowledge doesnt care who came up with the idea first... if it did.... I assure you plenty of people in history would need to be replaced by the actual thinker who came up with the life expanding ideas they have been credited with.

Yeah I was wondering if that's how it worked. Anyone have ideas of reasonable priced press that gets up to 2.5k psi to 3k psi?

check out @710whip 's press. $550 pneumatic dual heated plates.

i encourage everyone to avoid any press that's modeled on shirt or hat presses. the big plate shirt presses are especially ill suited for pressing rosin IMO.

fwiw i spent $125 for a six ton shop press, several steel bricks, an electric single burner, and a pair of ove-gloves (already owned an IR gun). 2000psi on 2"x3" packets.

Shirt presses with one heated side are indeed no dice for rosin, even with both sides heated, we've seen that we don't get as much pressure as we would like ideally.

That 710whip pneumatic has other problems though. It requires a separate compressor, these are noisy as fuck generally (seriously, most compressors I've worked with are as loud as a lawn mower!) and are obviously an additional cost. Quieter models are surely available at additional cost though.

I would heartily recommend that people just do vise, shop press, bottle jack etc mods until a comprehensive all in 1 purpose made solution with no trade-offs appears on the market, with a strong warranty and consistent results behind it!

I'm in the process of putting together my vice press, got myself a high quality properly calibrated lab thermometer (costs more than the vice and cuni plates put together lol) to ensure that I squish at the right temps. Can't wait to not have to put so much effort into pressing flowers. ATM I squish them using a straight iron and lift my entire body weight above it by pressing my hands down on a heavy, flat implement on top of the straight iron so that my legs come off the ground and my entire body weight is brought down on the iron. This is the only way I can get enough pressure and if I do not balance properly, I can and have already injured myself one time!

It is crucial to get a proper squish setup for flowers IMO, mind you hash squishers will have no problems sticking to just a straight iron.

Do you have a link for it or are you talking about mr rosin press for pre order? I don't quiet trust myself on diy like that. I don't see pics for it either.

@herbivore21 I use a vice grip on an iron when I have no tane. My wife and I don't weight much.

I'd like to try rosin with a good setup where I can fine tune psi and heat for each strain so I can increase yields.

i didn't know that about the need for a separate pump for the 710whip mr rosin press. pneumatic is not ideal anyway IMO. i like being able to ease into a press with gradually increasing pressure rather than one punch at full force.

i highly recommend the shop press with steel bricks like i'm using. it cannot be outperformed for the price.

if i were going to spend any serious money i'd only give it to @hashtrodamas (@thehappybuddhapress) or @_goldash (@hardpress_co).

@heady blunts where do you source the steel bricks from? trying to decide if I should go that route or the CuNi route myself for use with a vise. I have absolutely zero complaints with the c clamp vise grips and straightener i am currently using, but the straightener has to die someday

i got mine at a local machinist/metal shop. called em up and asked if they could cut me four 2"x3" pieces of 1" cold rolled steel flatbar and they said, "can you get here before 4?" and charged me $20.

might be fun having several sizes to experiment with.

ooo another great tip from the icmag thread, from ganjapharmer, you can heat the steel bricks on an induction burner! you can even stack them.

for around $100 you can get a single induction burner with a digital temp controller. that would be pretty sweet.

i just got a $15 dollar solid electric burner and use my IR gun to check temp. IR is not super accurate on shiny surfaces (emissivity issues) but the cold rolled steel is pretty dark and the rolled faces are smooth but not shiny like the cut edges, so i temp off the face at an angle and get very consistent readings i feel are accurate enough.

The induction burner is a good idea, sounds like it would work better than a normal heating plate.

If you place the parchment on the plate first, you should get a more accurate reading and get around the emissivity issue.

What do you guys think of this shop press? I found out today no stores sell any presses. http://www.amazon.com/Hydraulic-Pre...d=1448420703&sr=1-18&keywords=pneumatic+press
Looks like a rebranded version of the one I'm getting soon and similar to @BoogerMan's press. Should work fine. If you're in the US you should probably check out Harbor Freight too. It's not something you'll fine in most consumer-focused stores but maybe try places that carry automotive tools or that cater more towards small business.

I've been vice squishing some delicious greasy clear pale white/yellow shatter in significant weight using my vise and another hair straightener! lol

Definitely getting enough pressure and I daresay slightly more than enough heat to get all of the goods out of my nugs in at least 20% yields and often 25-30%. This is not a bad way to pass time inbetween bubble runs. Goodbye initial extractions with solvents, hello solvents being reliquished to dewaxing (and even in that use their days may be numbered in the a future looking less and less distant) and sub-micron filtration, still got some new ideas that will render solvents redundant for at least one of these purposes.

Definitely not sharing more detail on this project until I do some more work and ensure safety and check some assumptions but you guys know where I'll be returning to to share first once I am sure it is good to share ;)

In the meantime, I am loving using a setup that can squish nugs in reasonable time and without risking injury now!

Still, I'm looking forward to cuni plates being added into the mix so that I don't have to be scared of accidentally sending another hair straightener to the big salon in the sky via my vise!

does anyone know where do get a quality bottle jack? my second harbor freight jack is already failing at the seals. the press frame is still in good shape so I just need a 4 or 6 ton jack that can be used often without breaking.
