Yea gotta love Michigan winter I can leave dry ice in the yeti cooler outside for a week lol
I also leave material outdoor to help get it nice and cold
I pick up the whole trash can and take it in the lab and it keeps everything cold while I filter it
Yea I use a vaccubrand diaphram vac pumps flow rate thro buchner is ok but I’m trying to do 4 gallons cold it takes forever
with yea just particulates in the etho I use buble magic 220 micro bags to wash
I like it. I’m thinking I could use a big trash can with dry ice and a small trash can inside containing the biomass and Etoh. Easy peasy and cheap. Just get a cheap vacuum pump from harbor freight and a large plastic Büchner like this with filters and collection flasks and you are in business.
It brings the etoh ph down to 3.5.
Re: d/I directly in etoh.
Please, treat it like medicine, not trash!
At a min, find yourself a food grade hdpe barrel for the biomass. For better heat transfer, get stainless.
A used beer keg should cost you less than $50, and you can remove the top to make a 15gal pot trivially.
You can also get all kinds of fancy with keg mods. Those $100k CUPs come with kegs…
Great advice.
Thank you for keeping us on track.
