The simple pot still comes to us from simple roots buried in antiquity, but consists of a vessel that you can boil liquid in, and a condenser that condenses the steam given off back to a liquid. <\/p>\n\n\n\n

I outline alcohol recovery stills in 9.4.7.5, which includes this simple design, but I\u2019m also including it here for continuity:<\/p>\n\n\n\n

This design is based on a stainless asparagus steamer for the still, and I used copper coils in an ice bath for the condenser.  I provided controlled heat by placing the asparagus pot in a Cuisinart electric fondue pot of hot oil.<\/p>\n\n\n\n

I already had the asparagus steamer, stainless salad bowl, and fondue pot, as well as fasteners, so only had to purchase the copper tubing, bulkhead fitting, and compression elbow.<\/p>\n\n\n\n

Likewise I repurposed an empty plastic cat litter bucket to support the condenser over a 1.75 liter Everclear bottle, by cutting reliefs in the sides and top.  <\/p>\n\n\n\n

Here are the components required to convert the asparagus steamer:<\/p>\n\n\n\n

Note O-ring on lid.  The wooden beam is a piece of oak I had in the woodpile, as was the \u00bc\u201d all thread and wingnut.  I drilled the beam as well as both the handles on the steamer to accept the \u00bc\u201d all thread.<\/p>\n\n\n\n
