As I said pretty simple
pressure cooker has a nipple where a pressure gauge went
piece of Water line hose pressed on to nipple
fill bowl with alcohol ,cooker on stove top burner use candy thermometer, to set temp . I keep below water boiling point about 180 - 190 f
hose goes in pail of ice water alcohol comes out as steam drips in container
wait till no more steam open pressure cooker remove bowl & scrape
Easy Peasy may not be new, shiny & expensive but works cost maybe 2 bucks
Hell granny use to make homebrew, in a canner on the wood stove
