I have just made a small 4 plate Flute 42mm pipe 520mm long 6mm pipe attached to sieve tray Dephlegmator is 170mm long with 6x6mm pipes site glass is 35mm works well getting constant 90% from 20% wash 3 plates bubble all the time bottom plate only bubbles some of the time any ideas please

holes look too big. at the viscosity of alcohol/water will fall back through your seive if there is not enough vapour speed to keep it on top of the plate.

water falls through 2.0mm holes. a high abv alcohol falls back through smaller holes as it is not as viscous...thry holes in the 1.8mm size range, one hole for every 30 watts of power as a jumping off point. (like 200 holes for a camco 5500w element)

20%wash? IS this from a ferment or from a stripped run... if your making your ferments 20 % you need to dial that way back. Your going to stress the hell out of your yeast giving you less of a keep cut.

Just my 2 cents.

Btw average is between 6 and 10, with the majority around 8%.

thanks for reply 20% is from a stripped run Thanks for info on size of holes this makes sense as i did reduce the heat and this is when the problem started
