whiskeytango Posted April 21, 2020 Share Posted April 21, 2020 Hi I have a question. When im running my two column still 4 plates on the first and 16 on the second column. It seems like the second column is crating a vacuum and not letting the reflux drain back into the still. Has anyone seen this? Link to comment Share on other sites More sharing options...
Silk City Distillers Posted April 21, 2020 Share Posted April 21, 2020 Yeah, usually it's the higher pressure in the pot holding back the condensate draining. The pressure drops as you move higher in the column. Typically you might see something like a P trap and a dip tube on the boiler to ensure the drain is submerged.

whiskeytango Posted April 21, 2020 Author Share Posted April 21, 2020 It has a dip tube that is fully submerged at least a couple feet. If I have both drain valves closed and open them each just a crack I dont get the suck from column one to column 2. but if I open both It will suck the liquid out of the bottom of the short column one and into the bottom of column two.

kleclerc77 Posted April 22, 2020 Share Posted April 22, 2020 What I've found is running your steam pressure very low prevents anything charged in the kettle from pushing up into the second column. There is a definite PSI point for us where it starts to happen, so we keep it well below that. That being said, I'm still struggling to get a consistent 190+ for a whole run because we can't hold our steam pressure at a steady PSI. Link to comment Share on other sites More sharing options...
