Ets mep thread

I’ve been researching and watched quite a few videos. Been doing oil for a while now and it comes out clean. Just want to be able to run sub 80c. Can’t do that with hydrocarbons unless you have pressure as the boiling point for propane is sub 40c. I can run the crc at sub 40c but I seem to need to use media with more surface area running like that. Like I said im limited to my location. Its been a fight to get any classes or training done.

…and?

that doesn’t mean you get to skip the required reading. means you should have started six months ago.

why do you think you need N2?

if you can’t type the temperatures correctly (that’s -80C and -40C), and talk of “mother oil”, your “research” hasn’t been particularly well informed (Redit? Facebook?)

do you have the ability to cool your solvent and columns to -80C? why do you feel the need to go there?

it will lower your yields, increase your extraction time, and loose you more solvent.

this place is a gold mine. spend some time reading.

Seems the only thing wrong is my wording. Sub 80c is the same as saying -80c. We just have a different terms. Same goes for the mother oil. As I said in my earlier post, mother pil and food oil is based on where it goes next in my location. I have been researching as much as I can on here but until I do it myself thats all it is. Research. That being said what do you believe I should be doing?

75C is sub 80C

-95C is sub -80C

if the wording is wrong, then the meaning is up for debate. there is no room for error here. so making sure the language being used is on point is important.

pouring…into jars or onto paper. 5 grams from your “mother oil” onto parchment before any post processing. or 200mls into a canning jar. use the tools you have to make all the things before you try and modify your tooling because you’ve read that you need to run at -80C and use N2. become proficient in that which is infront of you. So you can more easily see how it might be done better.

you’re absolutely correct that to run below the boiling point of propane -42C (which is sub -40C) you will need some way to supplement the pressure differential. sucking from the other end works. depending on which pump(s) you have.

the MEP used to come with haskels, and the two stage versions will pull a decent vacuum. not sure what they ship with these days.

if you use N2 ONLY to push from your chilled solvent tank, then purging is simple. simply vent after you’ve injected. Understand that the vacuum in your solvent tank is now gone (there are ways around that). if you want to push from your columns into your evaporator, you now have a problem. How do you vent from a hot evaporator? Maybe don’t heat it until you’ve vented? except the heat transfer fluid in your jacket will freeze if you do that…(been there, done that). so now you have to push it back into your solvent tank along with the solvent…and get everything below -42C before you can safely vent. which is more work for your pumps. it can and is done. it’s not necessarily as much fun as you imagine it to be.

Out of curiosity, does anyone know the name or part number that this stainless steel fitting with this little green plastic adapter to connector lines for the pre and post condensing coils called? trying to replace some parts on an old used machine having a difficult time tracking em down , here a picture for reference thanks everyone

That’s a pex water line to npt. You’re far better off using a better connection and hose

I was just thinking that I think I just found it online but the temperature rating is what honestly keeping me away and I heard they will leak like a mofo

Looks like a push to connect air line fitting commonly used in heavy truck brake and suspension systems. They look and function like shark bite fittings and while convenient for connecting and disconnecting, they are prone to leaking.

They are definitely prone to leaking and so are the quick connects on liquid

Past -10° these will Leake almost guaranteed.
I’ve literally had to swap them out on over 12 mep 30’s for threaded NPT fittings.

Any regular hydraulic hoses work perfect for these applications.
Find one with a PTFE core hose, for excellent low temperature compatibility.
Any hose store can make these for you with NPT compression fittings, same day.
Very common in the food/beverage processing industry.

3 inch CRC with MeP30

input 6000g ; 304g return

75% silica/ 25% T5

Required 150psi of n2 to assist in the push.

That run sounds/looks so bad I can’t tell if you’re trolling

suggestings? troll…lol

use 75% b80 and 25% silica next time and you wont lose all your yield.

Even so, that ls a small yield. Ass-uming it was dry material.

Silica will grab less than b80.

It was the lowest quality trim I could buy. @ $8lb
