New extraction technique? Rosin tech?

just had a nice squish session today, hair straightener with clamp. Think i got about a gram out of 5 grams of small airy outdoor buds.

I find it funny how i run the same stuff, same technique, ect...and yet sometimes i get great results, sometimes just meh...lol. Best ive gotten so far was a small nug/bowl of abusive og that just dumped out a good size couple dabs, and it was neon yellow !!

stuff is goop at room temp though

still smokes great and tastes amazing...yum
 
Jointed - It's completely strain dependent. After extensive testing on my press, with a digital thermometer, timers, etc I can say that the RH of the starting material does make a difference, but only slightly. I can press 3 strains with the same conditions and get completely different yields and consistencies. I HATE these strains that press into liquid goop, such a PITA to collect. I find that leaving them out overnight to "dry" a bit seems to help and they're easier to collect with a big flat scraper the following day. From now on I'm only growing strains that press and collect easy with a good yield (Kosher Tangie.... mmmmmmmm best rosin flavor I've ever had in my life and I just got my hands on a clone :) )

I can collect almost any type of press extract with my big roller. If its super liquidy, use a razor to gently scoop most of it up, then use a large glass roller to roll up the rest. if you leave it overnight you are losing gooey terpenes.

OK, sorry about the slightly off-topic question above but I did a little shopping so I'll share what I bought.

I have been using 6" x 6" square platens and simply putting the package close enough to the edge so that the rosin could flow freely out of the heating zone while still not allowing the package material itself squeeze out. This was fine while I was experimenting with different packages but, at this point, the round puck seems to be working well for me so I am going to keep in that direction.

With that in mind, I saw a set of commercial platens that looked nice. They were round and just slightly larger than the chip that remains after pressing one of my pucks. That seemed logical so I bought these...

3" in diameter and 2" thick. $15 for top and bottom platens.

To heat them, I am trying a couple things. First is the tried and true cartridge heater. We have already discussed how the specs require that the tolerances to be very tight for optimum performance but I will hand drill it and if the cartridge heaters get hot and heat the aluminum plate, then they work for their intended purpose. For under $10 each, I bought an assortment of flavors. Progress, not perfection.

The second thing I am trying for heating is a band heater. This is the first I have seen of these and I have not heard anyone else mention them so I don't know how well they work but.... we will find out.

Unfortunately, this stuff is direct from China so it will be a few weeks before experiments can begin.

What I am wondering is if I will actually get more yield or a different quality by allowing the rosin to escape from all the way around, rather than pushing it all one direction as I am doing now.


OK, a couple things related to this post and another I made....

The collar heaters arrived today. I slipped them onto the round aluminum platens and attached a 110v plug.

Awesome... the cylinder of aluminum heated up amazingly fast. I did the first test without a dimmer and the cylinder measured 310F in the center of the point of pressure.

I put the unit on a fan dimmer (same as I use for the PTC heaters) and very easily adjusted the temperature down to a pleasant 230F - 240F.

No drilling. No milling. The collars a very adjustable so your cylinder diameter can be less than exact. Cheap. Easy. Less than 10 days from China to Central USA.

I give these an 8.5

And, not related to the post... the Olive Oil test was almost equally as successful. The oil was an excellent carrier. The big question now is... will it separate. I am going to try this again with Vegetable Glycerin. SkunkPharm had some problems getting Vegetable Glycerin to infuse with cannabis. Perhaps this method will achieve.

I will press 1 gram in olive oil and and give the result (orally) to one of my volunteers. Generally, a 1 gram treat (like a Firecracker or one of my classic "Everclear" drinks) will get them off. I'll see if the rosin from a 1 gram press will do the same to them. If so, capsulizing olive oil caps might be a nice option for some who like to medicate orally.

The one very successful oil press that I did do resulted in a rosin that was runny enough that when I folded the parchment in half and left it "on it's V" overnight, all the rosin and oil collected at the V. I'm sure if I add a little heat, I can get it to flow.

Are you doing any extra heating to decarb it?

Has anyone tried heated roll mills for squeezin?

What's this roller you speak of?

I was just pondering some ideas based upon roller designs like a lamination machine.

probably 5000lbs is the rated capacity not PSI.

if it were 5000 PSI then using their smaller plates (4"x6") you'd have a 120,000lb press or 60 ton capacity.

no C-frame press is gonna have a load capacity much higher than 3 or 4 tons. higher load ratings require A-frame or H-frame designs afaik.

i just pulled the trigger on one of these little beauties :biggrin: 10 tons of squishing power!

Been Squishing flowers daily for a few months, and sometimes bubble. From my experiments, I can tell that Rosin made from flower has non-visable contaminants in it. My tools stink like RESIN and the Rosin turns black on my tools when I vape. However, bubble hash only leaves Amber Rosin on my tools. I think of it is like when people water cure buds or trim before making edibles, the water is full of garbage/chlorophyll. After a few washes the water is clean. Making Rosin from flowers appears to also pick up unwanted substances. Don't get me wrong, I like pressing Nugs and my hope was to provide myself with a solvent less extract. The problem I see is the black RESIN produced by flower Rosin. Black reminds me of Carcinogens. So, in my personal opinion...flower Rosin is not as clean as we think. I am going to try to prove my theory by water curing a bit of flower and compare it to the same Nugs properly dried. I will share my results.

That looks like a good press heady and price! Do you have plates for it already or do you have to get new ones made up?

i've got an order in with mr. greyfox for heated platens.

that's a very beautiful machine pangea! what kind of preparation do you imagine doing for the pressing material to feed it through the machine? ideally you'd just hook a hopper up to something like that and let it roll.

breeder steeve was psyched on some of these alternative models for a while, but they seemed to all present issues for pressing bud. did you check out the screw style machines?

Ive been looking into a few different press styles and such for non rosining but with rosin still in the back of my mind. Screw styles seems like they'd be hard to collect your concentrate, and maybe tough to get it right with friction producing a lot of heat and compacting and shearing issues, non localized area's of reaction/uniformity of the forces, would produce not a good result imo, but im new to pressing so im just guessing.

Heard nothing but good things about mr.greyfox stuff, looking forward to your presses!

Well my dabber doesnt really produce black resin, and the reclaim i collect is a nice cherry red color, thats one thing i have noticed compared to reclaim from butane extract, flower rosin reclaim is a nicer red color.

but that is neat how bubblehash does that. is it only bubblehash, and not dry sift too?
