The strongest alcohol I can get is 99% I so or everclear maybe. I have plenty of 91 Iso already

the denature alch or paint stripper
has a freeze temp of like -167 ..........so the dry ice in that will not cause it to freeze up so it will transfer the heat in anything more effectly then anything but liquid nitrogen
when u are done u still have the alc to use for the next run

the alc and the dry ice are like a bucket with ice cubes ........but more effective less ice will be needed less time better results as u can never get that reaction with out the alc acting as a fluid to wick away the heat
it never touches the plant material or the oil .......is only acts as a fluid to transfer the heat/cold (same reason why ppl die in cold water in under a min all the body heat is wicked out)

So just using dry ice is a bad idea it seems like from what you're saying right? And if so where should I get the alcohol.

no it works ........it would take 1 or 2 hours with that
the direct contact to the metal would transfer the heat inside the materal .....but it will take longer as u can not cover the whole area u only get the points of contact from the shaving/chips/chunks u use

it comes with one 30 micron gasket screen I ball up a coffee filter on the other end

Where the butane goes I gotcha thanks I saw that on a YouTube video was gonna ask about that!

I live in California and it's super hard for me to get anything besides Iso I can get 90 or 95% denatured alcohol maybe from a store like lowes but I think my best bet will be putting the colum in a garbage bag in the ice chest full of dry ice

so if I'm understanding correctly I shouldn't freeze starting material to long because it forms ice crystals which then leaks junk into the oil ? if so at what temp should the starting material be cold at and for how much time?

When it forms ice crystals it's the moisture from the material you're blasting which ice crystals break the plant and allow more chlorophyll to be extracted which means more dark color and waxes

damn I thought it was the other way around I would freeze my ground up bud put in the freezer over night then soak then blast I'm gonna try a run with room temp material

I heard about the crystallization of the material by freezing when I was doing a bubble hash run a while back, have you ever considered putting a filter on opening at the bottom to keep waxes from getting through do you think it was affect the yield I saw terpbros on YouTube do it.

I had to filter my last run due to blow back and it did produce some clean oil

when i washed my material i plan to blast about a month ago i got a 26% yield its a untrimmed bottom nug and larf run, i plan to run some slightly less trichomed material for my first blast in case anything goes wrong lol. i plan to setup and run a little butane through the system before i even blast to ensure its operating fully. i should receive my unit before wednesday and will be running as soon as i get it. my idea is to get dry ice and freeze the butane at while i pack my column and then throw the column in the dry ice for about half an hour so the butane will have sat for a while along with the material, i plan on putting 1 unbleached coffee filter on each end of the unit inbetween the material and gasket meshes that the cloumn have and am planning to soak for a total of 3-5 minutes depending how long it takes me to get the solvent into my column. i will have a 180g unit and plan to try and pack 100g of material for the first blast to get even numbers on my yields. i will be using power 5x butane it has always been my favorite for blasting.

yes the crystals do what he said but they form large ones and those can be pushed out when u blow
the colder the temps the faster u need to run the system to keep that from happening
dry ice and alc .........your looking at a max of maybe 40 mins .....do to the fact it -109 and the fluid wicks away the heat
dry ice contact points only about 2 hours
regural ice .......12 24 hours

@Kodakle I bought the 180g cc pressurized extractor from best value vacs. I do not smash my material down when I pack it, just a light push to keep any large pickets of area out that would not have bud in it.
I have yet to get more than about 65 grams of dry material in my tube, and that's with leaving the tapered end on.
I wish I would have went larger considering I'm getting 1/3 the volume I expected. Just letting you know!

I got my first run to fit 88g of dried trim I packed fairly tight but never found myself using to much force. I got a 12g return on the 88g so far as it's not fully purged but was stable enough to handle and weigh after the muffining and piling together.

Dude thanks for the coffee filter thing my first run it saved me wasn't being careful enough and had a little blowback but no material came out luckily. I just got around a 12-14% yield on my first run of 88g

I don't know exactly how you guys do yours obviously but I use cured sugar leaf with popcorn buds that have only been cut once or twice to reduce size.
With this in was only able to get 65grams.
If you dry yours out completely, I would think you could get more. Don't know if you do that or not or use something I don't like dry ice.
I freeze my cans for sometimes a days or just an hour if I'm making on the fly. I don't freeze my chamber. Either way I pulled 12.4 grams from it so around 20%!
If I could get more in with same yield I'd like to know how please
