Open Blasting a lb time?
- Thread starter icdog

It all depends, I never open blast 1 whole one at a time, I've done close... maybe 200-300 grams, only because if I was open blasting it was to single solvent dewax, and anything more than that caused issues with my buchner funnel. On the other hand I still would blast 2-4 ozs (per blast and cut it up into smaller batches) at a time to keep things safer and more consistent with less time exposed to open air. It all depends on surface area, and water heat. I assume if you are blasting with cold tane and a frozen tube it would take me sometimes a minute and a half per can to get through.
once you get into a groove you can get throught it quickly. just take a few minutes to prep and make sure everything you need is at your work station and ready to go so you can just blast away. unless your dish is getting somewhat close to full i wouldnt even worry about it evaporating before your next blast. that said i wouldnt let it get more than 1/4 to 1/2 full of the ran butane so you wont lose any from spilling, just make sure you have plenty of hot water close bye so you can add it to the butane cooled water bath to keep it boiling. (the butane, not the h2o) this will also help with the initial purge as well. i keep the water bath around 140F. you can go warmer , just dont go over 170f.

to preserve the most terpenes possible we do our waterbaths.. below 120.. our tap comes out at 122.. by the time the butane gets to temp its down to 100.. anymore then that is just removing terpenes .. and slowly decarbing. making for a sticky product.
low and slow.. on the water bath.. and the vacuum purge for the BEST RESULTS
it all depends man.. u runnning how many tubes.. ? for a lb? are u prepacking all the tubes upfront.. and then blasting all at one time.. or are u going to need to empty and repack .. i mean theres alot of variables.. id say a good 2-6 hours if ur emptying and repacking .. for sure.. depending on size.. but honestly. 1-2 hours is very quick.. it really all depends.. if ur counting time as in prep work or just blasting after tubes are packed and ready to go ?
dont rush it . u dont wana blow yourself up.

then just do a run and see how long it takes u.. man lol. the research is here. ive seen mad closed loop threads.. with people showing there entire technique how long a soak.. this and that.. its all there..
no1 is going to come and say how long because everyone is different.

It take me between 4 and 5 hour's for blasting a pound using 18" x 2"
sanitary spool (around 100g.)Blast/unpack/repack blast again etc.

Thanks overbudjet.
With the mk3 1.5x24 tubes, 2 tubes pre packed, 2 collection pots with bottoms, 1 lid.
Takes about 2.5 hours to run 300g. That includes switching tubes and pots and letting the tank cool down.
With the mk4 2 x 36 tube, pre packed with about 1lb, 1 collection pot, lid and bottom.
Takes approx. 1 hour 45 min.
This is vac'd down to -19ish to leave a bit of solvent but the end material is ready to go in the purge system.

I run the mkIII with the 2x36 spool dry iced for 8-12 hours + dry iced butane tank, Takes no more than 1 hour to process 1 lb. usually more in the range of 30-45 minutes. I run 3 washes, and only use my soup warmer to introduce 80ish degree water as minimal as possible. I only vac down to 0psi, leaving some lower viscosity oil for me to pour without agitation to cause auto-budder.
Coming from a open blasting environment, I would only process maximum 2 lbs a day in material as when open blasting theres a lot more uncontrolled variables that unless you are in a downdraft explosion proof room that is completely a controlled environment you can have slight changes due to humidity etc. I would always split things into smaller blasts so to keep highest quality control with less exposure time.
In a commercial sense, if you aren't going for a high in quality consistent product, open blasting can process much more material than a MKIII per hour.

Very little, I might end up wasting a total of .1-.2 lbs of butane every run. Its still got just enough to where i can get most of the 40-80 grams out by pouring, I'm always left with 5-8 grams that is scraped and placed on another rack separate. I wouldn't really go by the pressure so much as the feeling. I feel my collection tank, to know the temp is right and where the level of butane is the entire time of the extraction. It's not safe to say 0 psi for sure depending on what temp your spools at. I try to pull it when the collection spool just gets to a good 55-60degree temp at 0 psi which leaves you a lil time to disassemble clean and move everything to clean area while having a low viscosity oil to pour.
I would recommend if you wanna start pouring just do your method and tone back the negative pressure till you find it low enough viscosity to pour most out with minimal scraping. There will be a sweet spot you'll know when you'll hit.

I'm using Viton Seals while blasting, though during storage on dry ice the seals are ptfe if any at all.
by the time the Butane in the tank thats -50 hits the column and washes temps are more reasonable(more like -10 - 0 degrees) for the seals. I wouldn't recommend using viton for long term dry ice storage or dry ice sleeved tubes.
Also when doing cold runs i've got eagle eyes on my extraction process, I've encountered leaks at times due to the colds, usually need to tighten something down.
