What's needed to start closed-loop extracting?

[420 Culture]

Aloha friends and family of the ICMag community. I'm stepping into the world of closed loop extracting full-time after a brief introduction to it last year. I'm familiar with the majority of the function & equipment, I just want to run everything buy the professionals here in the forum, and hopefully get some feedback to help create clean medicine for our patients.

First of all let me layout what I'm going to be working with for the equipment setup.

5 lb BHOgart extractor kit with a 6"x36" material tube

Across International 7.5ft CU. oven

Dual stage CFM Vacuum Pump

As far as the process goes I would love some professional insight that takes me beyond the basics, and the instruction pamphlet. Been digging around the forums for information, but in the long run I'm better off creating a thread for my specific needs.

Looking forward to everyones feedback, it is greatly appreciated!

??

How many cfm?

Sure you want to learn with such a big system? Be an awful lot of material to waste if you mess up...

 

[HighStateToke]

Yeah..that's a whooooole lotta trim in one tube man.

I assume you have your ancillary parts as well? Recovery pump, refrigerant scale, ect..

Not recommended to start on such a big setup unless its spent material. Basic instructions are useful if they are correct.

Running top shower (bhogart) style with a 6" diameter is inefficient. Those guys just keep scaling up without engineering a new design...I highly recommend just using a 4" or smaller.

Maybe get familiar with bhogarts smallest machine before going in head first, your mistakes will be cheaper.

Get a MKIII half lb kit and stainless hose set from Terpp. Buy either a Promax RG6000 or a Appion G5 Twin for your recovery pump. Then you will need a refrigerant scale and a 30lb recovery tank. Study Skunk Pharms MKIII pages and then get to work! You will be in for $2k or less and have a system you can scale up a bit

looks like 4k or more

I'm spending 1.5K to build an MKIII with bidirectional flooding. Hoses and recovery pump included in price tag.

looks like 4k or more

kit- 910, hoses 310, recovery pump 520-700, scale 120, recovery tank 80. Roughly $2k or less.

ok got ya,I was looking at all the bells and whistles,all you have to do is bolt that kit together??? no welding, 2k not bad
($210 welding)

Already got the equipment set-up ready to run, working with what I have, mainly what I need to get dialed in at this point is what methods to use to prepare the material, ideal solvent brands to use for maximum yield with this system, keeping in mind the large material tube.

While the material tube is on my mind, what should I expect for a yield ratio since there's a larger target area I'm naturally assuming it would be less, but how much less? Would it be worth it once we have our purging and methods dialed in to purchase, or modify a thinner material tube?

Going to be spending a lot of time reading through SkunkPharmResearch this week, are there any other websites or forums that would peak my specific interest?

Yeah, check out the rest of the related threads on this IC Mag forum, as some of the best.

Check out Skyhighlers thread on butane testing of the major brands.

A top feed rainfall 6" X 36" tube would need some way to spread out the 1/4" (.049 square inch face area) stream from the tank, to uniformly wet the material in the top of a 6" (26.7 square inch face area) column of material. Does it have a mechanism for doing that?

I decided to use two 4" X 36" columns to handle 5 lbs, and ours flood from the bottom and use the top flood only as a final rinse.

Consider also recovery percent and recovery time. Recovering the butane from a 6" tube is tougher than a smaller tube, because it produces refrigeration that drops the temperature low enough to stop boiling. Harder to heat a bigger tube from the outside.

Since you are are already set up with one, perhaps you can report back after running it. Hard to compare what I get to what you should get, because we aren't running the same material.

For a rule of thumb, we are getting up to 28% winterized absolute, and as low as 5.7%, but averaging between 20 and 25% from prime bud, and yield about half that much on prime trim.

How you pack and run it, depends on what you want to end up with.

What you end up with is dependent not only on the process, but what you start with.
