Subject: [Distillers] First Time Success with Nixon-Stone head??????
Dear Sirs/ Ma'ams:
I recently built an offset head column still with stainless steel
potscrubbers. It is attached to a stainless steel 55 gallon drum. It
seems to have worked well on the first go round, but I have a question
or two. First, after bringing it up to temp, I could only continue
flow at about 84C. At this rate I was getting about 3L / hr. I was
very careful to discard the foreshots and I took special care to
separate all of the batches. Each one has a distinctive odor though.
The smell is that of tequila. While it may seem a great thing to
have 10 liters of tequila around, I prefer something else. The wash
was molasses/ sugar and red star yeast. Additionally, my tap water is
quite soft and is know to have calcium in it. Best I can tell the
alcohol content is extremely high. Please share your thoughts on this
if you can.
First thing Quentin is to get some copper in there. Without it you will not
be able to remove sulphides which contribute to "off" flavors and smells.
The second is to get rid of the molasses if you want a neutral spirit. It
contributes a lot of congeners that are beloved by those making rum, but is
instant death to a clean vodka. Thirdly, cut down on your product
extraction rate. 3L per hour is 50ml per minute, and that indicates that
you are operating at a low reflux ratio. Finally, it would be great help to
those trying to answer such questions if you could please give details of
your column length, its diameter, and the power you are operating at.
All the best,
