upgrading still question

[cryptic]

Hi everyone,

I am currently using a 13 gallon still with a 2" copper reflux column that is ~1 m in height. I have it packed with copper mesh. I am primarily interested in making vodka. However, my run time for this set up is about 6-8 hours. Lately I have been considering upgrading to a larger set up to produce more, better quality vodka.

In your opinion, would a 4" copper column (6 bubble plates) and a 26 gallon base be more efficient than the 2" packed reflux column? I realize the volume is doubled, and the column is plate vs packed copper - but if all things were equal would a wider column help with reducing the run time or at least produce a similar amount in the same time?

I can seem to find information on the efficiency of the column widths used, (although I suspect there must be some) or whether 6 bubble plates would be more effective than a packed column.

Any insights would be helpful, as I am trying to figure out if upgrading is worth the effort and $.

Thanks,

Paul
