I have have only done two runs with my Nixon/Stone. The first went
perfectly, sitting on 78.2c with good neutral spirit.
The second run not so good not being able to get below 80.5c. After
the first run I made some small changes these were:
(i) Chopped 8cm of the condensor jacket as it weas too long. this
(ii) added furthe insulation to pot lid, column joins.
(iii) The s/s scrubbers (17), replaced by 14 copper scrubbers & two
s/s.Survived the blow through test.
(1v) The wash came to 10cm of the pot lid. The first run it was about
14cm. Both runs I put a few drops of anti foaming.
Any ideas as to why the second run didn't go to plan.
