Re: Questions regarding reflux replacement and anaerobic fermentation.
- A 200ltr drum of water, in my experience, will condense a wash volume of about 25 ltrs where the ambient temp is around 22 - 28c and where product is taken at around 1 ltr per hour. Submerse a pond pump in the drum to deliver unrestricted flow of water to the condenser.
The above is conditional on bringing the wash to boil on whatever power level, then reducing power to around 900 watt allowing the column to equilibriate for an hour before taking product. Equilibriating then taking product at higher input temperature significantly heats the cooling water.
The setup with which the above is used is a Nixon-Stone design set on top a 50 ltr beer keg. The column is 50mm Cu and approx., 1200mm tall.
The condenser is as per Nixon-Stone design. It regularly produces 3.5 ltrs of 95%abv from 25 ltrs of 9kg dextrose and water wash, topped by Still Spirits Classic Turbo yeast.

> I would like to present you with two questions regarding fermentation and distillation. Firstly, would it be possible to get rid of the procedure of continuous water flow to the reflux container by replacing the reflux vessel with a large tank capable of holding enough water so that its replacement is not necessary? Secondly, is it correct that by doing anaerobic fermentation in an airtight vessel under a nitrogen atmosphere it is possible to reduce the production of ethyl acetate to a near-zero concentration? Mass chromatography measurements have confirmed this fact and it is supposedly being used with success, but I would be interested in your opinion.
