24515Re: Condenser Question
- Aug 9, 2007Gravity has to have it's way in a worm condenser and have a
continuous gradual downhill run to the output.
If you make a double helix for the worm, half the direction of flow
will be uphill and liquid doesn't like flowiing uphill of it's own
You would end up with a pool of liquid at the bottom of the double
helix that will block any flow. Eventually you will pressurise the
pot and it will forcibly blow the condensed alcohol out the end of
your condenser. If you happen to have a flame anywhere near the
output you could end up with a flamethrower.
