My new toy
- Ciao a tutti.
My new toy is finished: I have to thanks a lot Claudio that realized
it making a lot of acrobatic feats with his tools to build the
column, but the result is really nice.
Anyway: the column is reacting very well to any variation of
distillation regime, and it's also having a good capability to
separate the components.
Having the boiler at 92 °C the bottom column was 91 °c and the top
column was 88 °C. The middle comun was about 86.5 °C-
The delta P were some 2 mm of water column the bottom Venturi and 3
mm of water column the top Venturi.
This made me a little bit disappointed because my calculation gave a
delta P of 4 and 5 mm of water column, respectively.
May be I simplified too much my calculations, but next version will
have the Venturi sections a little bit more narrow.
The taste was good, but Claudio and me only tasted a little bit
because the column was new and it was too early to drink the
distillate: in fact the copper was still "nacked" because was just
cleaned inside with chloridric acid to eliminate all the oxides of
So, column need to form inside the patina of oxides to protect the
metal from any attack.
I'm planning to use the column this November to distillate some
second wine: at that period it will be perfect and I will report my
impression about the taste.
The conclusions are that the column work in good way and there is
still the possibility to improve it.
