Grossmiller Posted November 2, 2011 Share Posted November 2, 2011 I was wondering if anybody on this forum has explored other alternatives for the heat source of their stills. Instead of using a steam jacket or open flame, how about circulating hot oil around the bottom of the still? Any thoughts? Jason Link to comment Share on other sites More sharing options...
Absinthe Pete Posted November 2, 2011 Share Posted November 2, 2011 That is a common heat source as well. Here are some heat sources possible.

Jedd Haas Posted November 3, 2011 Share Posted November 3, 2011 I looked into heat transfer fluids a bit. The most common choice is propylene glycol (food grade) which can also be used for chilling. You can also use food grade mineral oil. The mineral oil goes to a higher temperature. Both are relatively expensive, around $800 for a drum of glycol and $1500 for the mineral oil. The glycol needs to be replenished periodically as it evaporates slowly; not sure about the mineral oil. Link to comment Share on other sites More sharing options...
Chasin' Tales Posted November 3, 2011 Share Posted November 3, 2011 I looked at induction heating but unfortunately it was very cost prohibitive. Link to comment Share on other sites More sharing options...
