Hmmmm....

There's also the cylindrical, mug heat presses. Not really suited to the task, but maybe spark some ideas for further designs.

Yes! Yes! more like this!

i saw a youtube vid of a guy comparing heat presses and saying cheap ones have less/ less evenly distributed elements in them, and he used his laser heat sensor or whatever those are to show the differences in evenness of temperature on his expensive one compared to a cheaper one. was a large difference he said, the middle only having the right temperature on the cheaper rig i think.

$23,000, but has dual auto panels and big surface area. Large ptfe sheet on base, 25 micron screen, even thin layer of chopped dank bud, press... Loading other side while pressing, then clearing matieral off/removing screen, and collecting from ptfe sheet.

Says 120 psi operating pressure, not sure exactly how much force that translates into. Although the thought about getting much higer pressure (and thus allowing lower temps) seem worth looking into. More experimentation on a smaller scale to dial in pressure/heat/time ratios and best ways of loading/holding materials (25 micron screen) and material variables (dryness, whole buds or broken down or slight grind?).

Although the Stalhs auto opening one looks solid for these smaller batches, at $1,500 for the 16"x20".

Digital pressure readout, easy adjustment...

Actually this one looks pretty legit as well:

Maybe something similar to this method? Heated screw press. I want to see some piles of "cookies" like that. @ 8min 35sec just imagine. Willy wonka style lol! https://www.youtube.com/watch?v=yvq6IS8EP3w

On these sublimation heat presses, do they only heat from the top side? If that's so, it should make a tremendous difference if also heated from below, or would that just get to hot.

Gave this a try today. My first attempt. first off I started with wax paper it only took me one try to relise that wax paper is a no no. parchment paper is what you need.

After that things went smooth.

First off i started with making keif out of some trim from a mix of indoor plants.

starting material



and the Keif


I then weighed it up ( it was 2.5 before I snaped the pic so for easier math Im saying I started with 2.5 not 2.4)


set flat iron to 340 and stated pressing with both my hands as hard as i could. and ended up with this


not easy to tell from the pic but there was 3 distinct quality's i could see. the center had the dark dryer material that got tossed to the side. (it did have a lot of gooey texture to it, also I could visually see a bunch of the honey like material covering over the top so i decided to do a seconed run with it later.)

the seconed quality was very gooey and a nice golden color where it was thiker it looked a little like honeycombs. Made this
