I have 2 home stills that I use to recycle IPA. I just run one at a time. Only cost $100 on eBay and work great. I do have a large barrel type container for water that is recirculated to cool the IPA. I can do about a gallon and a half an hour.
Never have had the plastic bags work in the still. As they get burnt to the bottom and break of course. I used the baking bags that are supposed to take 400+ degrees. So, I have to do a bit of scraping but it’s cheaper than disposal through a service.
