Re: Lyne Arm Angle

It all depends on vapour speed and surface area. There is one real easy way to know if it makes any difference. Simply measure the vapour temperature going into the arm and coming out. If they are the same then you know the arm is doing nothing. Remember the purpose of the taper on the big onion sti...

Re: Stripping runs at Woodford Distillery

I do like Woodford myself. This is somewhat reminiscent of the old discussion regarding a 1/3rd cut and a 1/5th cut. A similar process is used in distilling cognac where the HEARTS is split into two factions. One is prime quality and the second is not as good and is re-processed in the next batch. T...

Anyone with any sense at all would have told you that if it wasn't good enough to drink, it could be re-diluted and run again.

Re: Stripping runs at Woodford Distillery

You say it's a waste of energy yet some people wait 2-3 weeks just to get a measly 10%abv. Why doesn't it make sense to at least run your still to the point that it's nearly putting out what you normally put in it? Sorry did not understand that. It does not take much energy input to do a fermentati...

Re: Stripping runs at Woodford Distillery

If you are following the clasical pot still sequence of beer (strip) still producing low wines, low wines producing either high wines or product depending on if it is 2x or 3x run, then you charge the boiler with low wines at 27 to 30% ABV. Now many folks run so far into their strip run that their l...

Honestly whilst the turbulators inside the vapour tube do work, if you need them it means the condenser design is wrong or that you aren't using it the way it was intended to be used. Is it a liebig condenser or is it a tube in shell "shotgun" condenser? Air cooled liebigs will work but they are bet...

Re: Heat source for alembic still - can't use flame!

Take your nice alembic and stick it in a double boiler. Depending on what is inside the boiler some of those heating belts will burn just as fast as a naked flame, because the surface temperature gets so high. Double boilers don't have to be liquid, they can be dry or filled with powders like sand. ...

There are other ways to decide the same thing, but it is just convenient. However, if you are running any sort of double boiler w...

Re: Preventing copper oxide

After doing construction or repair work on a copper still or vapour path you should do a deep clean with acid or vinegar. This is to get rid of flux and solder residues. To be honest though after that it shouldn't need deep cleaning. Copper oxide on the inside of the still is good because raw copper...

Ok assuming this is a standard encapsulated SSR it consists of a diac and a triac, or equivalents to do the same job. The diac and a capaitor (both internal) are in the trigger circuit for the triac. So is your pot. The pot and the capacitor are a timing circuit. The pot setting determines how long ...

Actually that was a valid comment posted a bit higher up by Danespirit.

The answer is that the bigger worm is NOT just condensing the vapour. It is also acting as a product cooler - hence the desire for the thermal gradient in the water bath.

Feints = heads and tails mixed together. Now off my pot still the feints are mostly ethanol contaminated with other stinky alcohols and ARE worth re-processing.

Re: running reflux feints in a column

One other thing to help put it in perspective. In the heads and tails there are other alcohols that are not ethanol.

Ok lets add a bit of clarity here. We are talking about a spirit run on a reflux column.
