New extraction technique? Rosin tech?

[204andpost]

I'm using a 20 Ton from harbor freight with 5" X 2.5" plates at about 225 F for flowers. i can comfortably press between 5-10 grams of dried plant matter per press depending on the material with this size. Any more and I blowout my screens.

Here's a shot of my press before I swapped out the bottle Jack for a pneumatic over hydraulic Jack so I could use an air compressor to speed things up.

Inside the plates are flat coils. Two per plate. The initial heat up takes about 20-25 minutes.

I'm guessing that 50 micron should be the max?

204, can't you use less heat and more pressure? What sort of heat should be used with a 20 ton?

If I press below 200 I see a lower yields and more auto buttering.

225 F increasing the pressure gradually in stages works best for me. With flower. I fill my plates to capacity so as the oil is heated it escapes quickly to the sorounding cooler parchment. At lower temps the oil travels more slowly through the material and ends up spending more time in contact with the plates, in my experience.

The stability of my flower rosin is generally a tangible pull and snap with plenty of flavor and none of that vaporized /burnt popcorn flavor.

Interesting, I'm just worries about losing terps, but a slower flow having more contact with the plates doesn't sound great.

How about hash, what temps ya using with bubble or dry sift?

Thanks,

this makes scientific sense, since water boils at 220F. to avoid buttering watch the ambient RH. parchment does a pretty good job of getting some of the moisture up if you allow everything to cool before collection as well.

90-75 for flowers and fresh flowers

25 for headies and sifts

hash you want as low as you can go, and go a lil faster on the press after the initial contact ease in.

you have to realize that the heads will hot tolerate much heat for long, but the bags cant take the blasting in force.

7 grams of hash into a 25 micron 2x5 bag, i usually press out in a 5-10 count

Good info lyfespan.

HGO, I press my hash and dry sift at around 180-190F though lower is definitely possible. I actually use less pressure on my hash / dry sift presses and never reach the full force of the 20 ton. I don't have a gauge hooked up to my press so I can't say exact psi. It's more of a feel thing. Like lyfespan mentioned, you have to ease into it being careful not to press too hard and burst your filters.

We've been dry trimming over trim trays lately and pressing out the dry sift collected with really good results. Nice returns and flavor. Dabs really nicely.

This is my modified arbor press. Still needs a little tweaking though

I'm regularly getting 18%-25% yields with flower. This particular sour jack isn't very pretty but is easily giving me a 25% yield of golden terpy goodness

A 1.5 gram nug gave me .38 of very tasty rosin

I stumbled across a set of 3x3 heated platens for $320. I might go for it but as it currently stands, its working great!

I just got 27% pressing a gram with my hair iron and c clamp, one press, on some bubba kush.

 

[Lapides]

40% here with only my warm breath and a clothespin. Not telling you the holy rosin grail i Pressed tho.

 

[Ringodoggie]

Wow!!!! 25%.... 27%........40%.

I just got 80% having my fat ass wife sit on a bud and fart.

Talk about flavorful terpenes. Albeit, it tasted a little "nutty".

^^ too late. I already powder coated my wife's patens in green and slapped a sticker on her. Pics on IG

So I'm not sure how many people out there are using dies to pre-press pucks before squishing but I tried it and im sold

I stole a scrap part from work that is simply just a cylinder that slides fairly smoothly through another piece of metal

I just fill the hole with some trim and press the cylinder down to make a puck. I've found it improves yeild and reduces blowouts. As well as allows you to squish trim without a filter

Notice the little circle of parchment I put on the cylinder to keep material from sticking

 

[Hashmasta-Kut]

i dont approve of that shape for squishing. you want it to be at least as tall as it is wide to start. a compressed cone of some sort would be primo. I make balls or super dense short snakes that have about an equal thickness ratio width to height. A snake form is more efficient than what you are doing by far, just think about it

ps, not trying to be a dick, just trying to help.

 

[20sackzack]

For sure I appreciate your input hmk you da man. I dont really get how a snake would be more efficient for my 2 inch round plates though..

Btw I wasn't trying to say my puck shape is optimal, rather that pre pressing your material with a die improves efficiency and allows you to press loose trim without using a filter

I honestly have no idea what my yeild percentage is I just noticed an improvement after pre-pressing pucks

Like what do you know its not like you invented the HMK or something..... oh wait a minute

 

[McKush]

That wouldve been funnier if i had made it in before you 20. Hopefully everyone knows i jest

 

[20sackzack]

Lol this is the internet so I'm sure someone will be offended

To be honest heady blunt's press die is what inspired me to try this out. He mentioned he wanted his material to be about a half inch back from the edge all the way around for expansion so thats what I copied. I am getting low on buds and needed a way to squish trim. This works amazingly well for that

Also didn't really chose the shape of my die. It was just a scrap part laying around my shop that I thought would probably work and it did
