I've read though a few threads in this forum on continuous distillation and they've inspired me to design my version of a continuous still using primarily StillDragon parts for a micro/craft distillery. But first off, the purpose of the continuous still: to process a fermented mash @ 10% abv (void of solids) at a rate of ~150L/hr to a low wine abv greater than 90%. The ~90% low wines will be further processed in spirit run for a final neutral spirit >95% which can be used for vodkas, gins and other spirits.
A few thoughts:
- All the components are SD parts except for the custom fitting which I'm calling a take-off fitting. (Please ignore the parrot).
- The column is 4" and perf. plates or bubble cap/DC plates can be used. Of course perf. plates would be cheaper.
- The picture I'm showing here is the still being heated by direct steam. I really don't like the idea of direct steam because the steam will have to be food grade. Untreated municipal water going through your plant boiler can shorten the life of your boiler really quick. Thus I liked the idea of a reboiler and the plant boiler remaining closed looped. The schematic shown here does not show a reboiler (that's my next design).
- The feed pump is not shown. Also, I have yet to consider instrumentation and control (which is not my forte) for data logging and safety.
Anyway, here's my design and a rendering of the 4" take-off plate in front and iso views.
