New extraction technique? Rosin tech?

[RulaTone]

rosin is not evap. and condense trick
its just a thermal release of oils by melting the wax membranes they are in.

that you post seems an old drawing, have a source?
seems just an apparatus for an other purpose, not specific to cannabis.
And the high temperature of evaporation of THC leads to partial degradation of the molecule itself, being a big and heavy one.
at the relatively low temps you make rosin there is very low degradation if all.

My chemist buddy and I discussed distillation and he didn't seem to think it was a good idea, either.

I did learn a couple new things today so I may as well share.

Regarding gathering this rosin off the parchment, I tested a nitril glove. If I dab the spot quickly, it sticks to the glove. If I press and hold and remove slowly, the rosin comes off the glove and sticks to the parchment. Worked fair.

I tried a rubber ink roller and it didn't do shit.

Considering the pressure we used, much of this stuff looks like it's soaked/pressed into the parchment so I may never recover that. No big deal. Live and learn.

Another thing I tried was folding the parchment in half with the foil side facing out and putting it in the hot sun. It's 85F and sunny today so that foil should hit 100F+. I thought it might just run down and gather at the fold. Well, the bad news is that it didn't run down to the fold. The good news is that this shit makes an awesome sticky bug trap. I got a bumble bee, a couple gnats, a fly and some odd bug of unknown species who managed to wiggle his way out and staggered down the deck railing. I'll bet that little fucker is high as a kite. LOL He's just sitting there shaking his head and licking his antennae. LOL

On the smoking front, I tried this rosin in my V-Hit Glacier and it works awesome. I was using a nail but it's a pain in the ass to get out the torch and heat the nail and blah blah versus grabbing my little "magic wand" (as Mrs Ringo calls it) and press and hit. I have the power turned down to 3.3 volts and the taste is very nice. I did do some at higher voltage but it killed the taste.

Just an update for ya.

Beautiful day today. Gigged last night and got shitfaced until 4AM. Need to get outside and sweat out some of that poison. LOL Later.

I saw a pic of the machine breeder steve is working on, looks interesting...

People are doing molecular fractional distillation with a kugelrohr but a larger scale setup is going to cost you about 40 - 90k mostly in glass ware and the details must be monitored precisely. Vacuum is measured in mm not inches and degrees by the tenth. RHH on here has a company called alpine in LA. They will take your black nasty oil and turn it into "clear" and they can artificially add back in whatever terpenes you want. There's a thread on icmag called "building a ic clearinator". You can check it if you want. The terpenes from herb are hard to recapture, especially all 20 of them so they just add back in ones from other sources. Thc will not steam distill but it's been discovered you can use a microwave to do it. Look at Chonkski's profile message board. Some one left links there to the process. This will be great for custom tailoring meds for people but not for mass producing dabs. I believe alpine charges 8$ a gram to turn your crap into clear.

If that design worked well, gw would already be all over it as he is an extraction engineer. When I was young I tried using a 400 ml graham condensor to vaporize and condense thc and it didn't work.

for people who want to gather it off parchment fairly easily, a 5mm glass or whatever handle with a tenmm cylinder end section about 1/2 an inch long works great for rolling up the extract. going to make some to sell soon. simple yet effective they be. scrape the glass collector off with a razor.

Sun, look at the press frame that Ringodoggy has, something like that more rectangle is what you want. You cant go to long without losing pressure on the ends. No wood maybe all thread, it has to be strong to take 10 ton, and there is still heating the plates.

 

[Ringodoggie]

I ordered some PTC Thermistors to test for heating plates (in whatever invention you're working on).

Thermistors are electronic resistors that maintain a fixed temperature. You can buy them in various resistance but I bought the 250C (482F) value. I can dial it down with a circuit board and put a controller on it. I plan to JB Weld (adhesive good to 700F) the PTC to whatever metal plate I plan to use and run the wires from the PTC to a circuit board for control and monitor.

I am hoping it will translate well into others inventions. I was not going to say anything until I got mine and had a chance to experiment but since some of you are having the same dilemma (plate heating) I'll toss it out.

Here is an example...

We are basically talking about the same type of press except for doing it vertically with a rectangle pressing area. How long do you think it will take to heat your plates, and how many are you going to mount to each plate?

 

[Sunfire]

I think you need to mount as many as It takes to get even heating.

 

[whadeezlrg]

harbor freight is a fun place...the majority of their tools aren't going to hold up like their more expensive counterparts although I love the place...just gotta make sure you use the 20% off coupons and always grab a free flashlight/mulitmeter/etc.

 

[Sunfire]

Wtf I had no idea about coupons and freebies!

 

[HashoftheTitans]

Wtf I had no idea about coupons and freebies! Well the jack was on super sale as is. 90 day manufacturers warranty. Maybe I should have gotten the 2 year for 10 bucks but oh well!

So the idea of super charging the shirt press isn't going to go how I want after taking it apart and examining it. I could for sure add some extra pressure with a wood frame and a small like 2 ton jack but the 20 will for sure bend the shit out of the cast aluminum frame the the coils seem to be casted inside of.

So I'm attempting to commission the burning man engineer/welder/genius. I know he'll give me a fair price on labor and knows where to get good deals on steel. I'm thinking of just a simple frame with plates that have coils and ss face and are digitally controlled. I'll just incorporate the jack, I really see no need to go for multi thousand hydraulic set ups. Maybe for larger machines in the future.

We must be close... I hear so much about this wild welding wiz, but have yet to meet him.

I think you're talking to me??

I don't quite see the horizontal vs vertical argument. With all this pressure, everything is being squeezed to the outside anyway. I would think that simply leaving one folded end of the parchment outside of the press area would leave some place for the rosin to escape and collect. I believe that was one problem with my last experiment. The rosin had no place to go so it got pressed into the parchment and spread all over the parchment. If I had just left one end out of the press, I believe much of the rosin would have escaped through that avenue and collected outside the press area. I'll try that next time.

I am looking for some suitable material for plates. Aluminum would be great. My last experiment with the vise and heat gun simply used 2 electrical box covers. However, the steel was not as good a choice as aluminum. Suitable plates will be easy to acquire.

I have zero experience with the thermistors so I don't know how much of an area they will heat. We'll find out in a few days. I plan the press area to be small so it should be easy to heat. We'll soon see.

Mounting is easy since the plates lay horizontally. I will use an arbor press for this test (don't we all just love Harbor Freight LOL) The bottom plate can just sit on the press base. I am attaching the top plate to a slightly flattened pipe that secures to the arbor press shaft with a set screw. It only needs to secure it enough to stop it from falling off when pressure is released and the arbor shaft is raised. I am hoping the JB Weld holds the plate and the pipe together. Won't know too much until I start testing. Seems pretty simple.

has anyone tried something like this ....a puck shaped pressing container and lid (that is pressed down in the container) with dozens of fine holes drilled in the bottom edge of the container so the rosin would be forced through when heat and pressure were applied...the container could also be machined with a collection channel around the exterior just under the holes.

I also wonder if two flat surfaces are ideal for making rosin?...would a convex shape work better? or would an upside down conical shaped (female) container with herb or hash pressed with a corresponding male shape be more efficient? I'm sure that an expert involved with pressing seed oils or flowers for essences would be able to offer excellent advice..so would some industrial chemists.

Yes, I tried this. You need a screen. The holes just don't keep back the plant matter. My holes were about 1/64 and when it reached a certain temperature the pot would turn viscous and squeeze through the holes.

I have not tried this method using a screen yet but it is on my todo list.

I am doing it vertically so the rosin can run into the trough...

 

[Ringodoggie]

From that picture it looks like the rosin went UP, not Down.

I just don't believe that gravity has anything to do with it. The rosin is going to flow the direction of the plates when they are squeezed together. The slightest variance in plates would push the rosin one direction or another regardless of gravity. Yes??

Does the rosin actually run and drip when you do it? Or, does it just squeeze out to the edges?

 

[EsterEssence]

Ringo what you are seeing up top is the top of the packet, here is a pic of it after squeezing. It is all about gravity. I am using kief not buds...

 

[Ringodoggie]

Cool. I see, now. I have a couple jars of dry sift I think I will try next. You seem to be getting pretty sweet results.

I wish we could measure the force in your setup. I wonder how well dry sift would squeeze under that 40 ton press I tried?
