Yeah, I also just bought a bunch of the generic ones and they work just as well.

They are nothing like parchment, nor silicone, so they take a little getting used to, you may not like them. But they have been working great for me.

Awesome guys! So the glass goes on top of the patties right away or you wait for a certain point? Crazy that all the solvent can migrate from the middle outwards successfully to achieve 0 ppm in 24 hours!!!

 

[HashoftheTitans]

Nice, Chonski! I will definitely try them out. I am going to try out some of these PTFE coated wire meshes as well and see if it makes a difference when purging etanol.

I just use one of my marble shelves to flatten my slabs when they get too thick for bubbles to pop. After flattening it out so many times, there are no more solvent bubbles.

Where does the gas in the bubbles escape to though? Out the sides?

So the ptfe mesh goes on top of a shelf or you use it as the shelf itself? Any spacers under the ptfe mesh if it's lit on top of the shelf?

Do you use a dehydrator sheet on the top with the marble or a regular parchment as the marble obviously won't let it breathe? How long you leave it on their? Or you just gotta watch it and get a feel for it?

What mesh size were your going to try first? 350 obviously won't work cause its only 7 inches wide. The 100 you could cut into 3 - 12" wide sections and the 200 could be cut into 3 - 13.3" sections.

I wonder if this stuff is gonna get weird to peel off because of all the micro divets the mesh will make?

 

[Hydrosun]

so page 33 and 34 of the AI thread now have all kinds of super cool links and products to try. Thanks guys.

I can't wait to see how these things work.

Any chance you guys want to start throwing pix up of your tech?

My review of Hydrion Scientifics oven: DZF-6050 1.9cuFt

Some parts are a little cheaper then AI's 1.9 like the door handle and door its self are a little more flimsy. The valve is brass instead of stainless. There's no one way check valve to prevent vacuum oil from getting sucked into the oven from a power outage or something. But all these issues can easily be fixed if its a big deal to you.

The good; The PID is awesome and has sweet back lighting lol so it matches the LEDs in the window. Its FIVE SIDED HEATING(im 99% sure) you can see the 2 heating strips on each side of the oven and feel that they are hot compared to other areas. All 5 shelves are holding a stable temp and only have a 3-5F difference from a top or bottom shelf to a middle shelf. Which brings me to the awesome shelves(you could get them cheaper locally) They are polished SUS304 and have 3 sides/walls for perfect folding parchment/Teflon too. They are kinda thin but seem to work well. Might look into aluminum shelves one day.

Im going to be selling my AI 1.9 and buying more of these. It was $2135 shipped to my door with 5 shelves. The shelf space per $ is the best with these 1.9s and i think the 5 sided heating is going to help a lot of my inconsistencies. At most ill have to rearrange shelves every 12 hours which i do anyway so thats not a big deal

FYI: I put these LED's on the door. I bought some clips so i didnt have to solder anything, some 90 degree strips to make it look nice. Total with extra led strip and clips and shit to do 1 or two more ovens if i bought more power supplys and controllers came to total around $35-$40. All bought on ebay from USA people, could have saved $10 buy buying from china and waiting an extra week but that makes no sense. With the clips and no soldering required i had these installed in about 15 min. SO MUCH EASIER then soldering but i also suck at soldering so that could be why.

EDIT: They offer customizing also.
-Programmable temperature controller for a preset temperature curve
-RS485 interface and software for the remote control from computer
-Independent temperature limiter for absolute sample safety
-Manometer (vacuum gauge) with digital display
-KF25 flange
-Up to 5 racks (2 sets included as default setup)
-A wide selection of vacuum pumps with/without fume mist filter and cold trap
-Additional inlet adapter for inert gas

My next ones will have the Digital vacuum gauge and the inert gas inlet(pissed i forgot that on this one but oh well)



Trying to give you all neck problems with these pics lol

sounds awesome for curing slab sandwiches on wire racks. Nice Find!!

I just sandwich my slabs for 10-20min to flatten it, I don't purge like that.

And I use the ptfe in place of parchment paper.

If my product is very sappy from the start, I'll use parchment paper first, and then use the ptfe sheets to finish up

That is actually really cool, I didn't think something like this existed. Would be cool to try a run on it. Thank you for sharing

I have been speaking with them since ive canned the 2.3 Elite and I learned they infact have a 4 sided heating system with 2 long heat tubes bending from wall to ceiling and wall to floor. I am talking to them about using heat mats as we speak.

 

[Sunfire]

The keda ones that hardware factory store sell are 3 sided heating I just found out. Plus the warranty is through them and not china. Fuck AI, in my opinion.

I talked with the HFS guy at the HT Cannabis Cup, he wasn't up to a discussion of how his oven was heated. AI imo is much more knowledgeable and understanding of what you guys want, I talked with them at length at Chalice.

Been thinking of grabbing an AI 0.9 from http://amzn.com/B009WSJNNQ

Can anyone recommend what level of cfm I should be looking for, or a link to a nice pump. Would like it to be 500$ or less.

I think a lot of package deals come with 2.5 cfms and in the past gray wolf had been recommended to me a 6 cfm pump.

go bigger.... oven space is the limiting factor for EVERYONE and the foot print of the next size up insn't much bigger...

Just go big....

On the pump too...

 

[Sunfire]

Yes the 1.9 cubic foot oven internal space is 16x14x14 which fits a parchment sheet very efficiently on each shelf.

If you have 1/4 fittings and lines you don't really need more than a 1/2hp 4cfm but I got a 6cfm cooltech anyways. You'll never move more than 3.5 cfm through a quarter inch line and my little 5 cfm jb platinum pulls 10k micron pretty fast on 1/4".

You should really look around before you ask these basic questions because I have said this in many threads many times...6cfm two stage 1/2hp robinair cooltech with gas ballast valve for 320. 6cfm two stage 1/2hp cps with gas ballast valve for 270$ I think are the best value for the money. There are multiple threads discussing peoples opinions of pumps. If you get a cheap Chinese one or a Viot hvac, you'll be sorry. Centurytools and amazon usually have the best prices.

HFS doesn't need to know the technical details, it's a keda dzf6050. Order them direct from China if you want but when it comes in the mail beat to shit, have fun dealing with the warranty through china.

Even after AI dropped their 1.9 price to 2k, it's still expensive as shit after tax and shipping. AI isn't very easy to get bulk discounts through either. I live three hours from sparks but I drove 8 hours down to LA for a reason. After tax a keda from HFS is 1850 and free shipping. Don't tell them I said anything but you can get good bulk deals from them.

 

[Humpi]

Hi

Chonski what is the reason you use parchment before the ptfe if it is sappy?

Also some local person that works at a head shop has been telling me to stay away from parchment and use silicone sheets instead. I am assuming he's full of shit and just wants to sell me his crap? Because most of the pics I see online, people are using parchment.

Lots of good pumps out there. Even a single stage pump will pull under 100 microns, which is enough to boil the cannabinoids at room temperature.

To my eternal damnation and discredit, I'm both cheap and impatient. I want it all in my hand, RAT NOW, if at all possible!

More is better and too much is almost enough, but I'm also a tattered old manufacturing engineer, who spent a life time enabling the production brothers and sisters, so have some of the corners broken off and rounded from collisions with reality.

A single stage pump will accomplish the task we covet, and even the leeeedle ones will eventually achieve our desired pressures, absent excessive leak rate, sooooo how much money do you have and how much prestige can you justify?

Some brothers and sisters have done a bang up job using Harbor Freight pumps and just exchanging them when they go south, which is probably the best bargain, albeit a little hard on Harbor Freight, whom will eventually get wise.

I picked up a CPS VP6S as my first vacuum pump to be used by my very own self, but bought a number of Stokes vacuum pumps prior to retirement and highly recommend them, if you can afford them, especially their 412 MBX and 1722 package with ancillary Rootes blowers to more quickly achieve "rough vacuum."

The Stokes are extremely reliable and I would buy one of their smaller units if I was bucks up, but I look at money out of my fixed retirement income differently.

Does it do the job, for how long, and how much does it cost?

I've purchased American made CPS VP6S as low as $134 ea off E-Bay in lots, and never paid more than $200 for a one off delivered to my door step.

I've purchased more than a dozen of them, and the original one I have been abusing since about 2009, still pulls below 100 micron

In addition, none of the others I purchased have ever been returned from failure.

Certainly prettier and more prestigious units available, but there is a lot to be said for good enough and utility at the margin (bang for the buck)!

You definately will want to step up from the .9 to the 1.9 for sure. if not because of the size then because of the design. shelf holders in the 1.9 are tracks vs clips in the .9. heating is 3 sided in the 1.9 but only 1 side in the .9. its only 500 or so more for the 1.9 and the design is worth it. the .9 is good for... um..... making cookies? drying sieve beads? recharging filter dryers? i wouldnt use it again unless i had to.
