Re: Please review and feel free to update the continuous still design
- I hope you understand that with this type of continuous system you
still need to do a separate rectification run to get rid of heads. If
you want it continuous I do recommend some level of automation. Needle
valves will not hold their calibration in application like this (as
has been shown).
For just a plain stripper you should try Automatic Feed Control (AFC)
as has been discussed here. One of our members built an air-cooled
version that put out some serious amounts (several liters / hour) of
65-85% stuff. If you want it higher you can in theory (haven't had
time to test this) add ARC on top of that and get 95.6% stuff out of
Here's a sketch of AFC-ARC combo that I may build one day time
permitting - I have all the parts, just need to put it together and test.
The lower part has been tested and it works well.
