home still: condenser

I finally completed the condenser portion of the still. From the last update I brazed the coil into the main tube and added the collection portion of the condenser.

This update took a little while because I was contemplating my approach for the collection portion. I eventually decided to approach it as simply as possible with a flat plate and a short tube up the center. These pieces were brazed to the stainless sanitary fitting and the fitting was then brazed to the outer tube. The center tube could be extended in the future by slipping another tube over. I will experiment with this to see which works better.

The condenser works by having the vapor come up the center through the small tube and condensing onto the cooling coil. It then drips downward and into the collection area formed by the plate and the two tubes. The liquid drains out through a tube on the bottom of the collector.

Completed condenser.

All the copper tube sections are completed. The next things to work on before testing the parts are the heating controls for the pot, and cooling system for the condenser and dephlegmator.
