Tim has a bit about his garbage bag and rice cooker alcohol still…
“A still has two parts, a boiler and a condenser.
A rice cooker/warmer makes a great boiler.
It’s got a rubber gasket so all the steam goes out the vent. It’s insulated so all the heat goes into the mash.
A plastic garbage bag makes a great condenser.
It’s got lots of surface area, cooling and condensing the vapor very quickly.
In my experiments it didn’t need to be vented and hardly puffed up at all.
I tested my still by distilling a gallon of “rice wine for cooking” which has salt added to it to keep people from using it as a beverage. I put the bag in a tub to keep it from rolling off the table when it got heavy, and in case the bag leaked.
The whole system works great!
Finally I was able to use up that gallon of salty wine, which I inherited from a friend who moved back to China.” – Link.
