Fruit for fuel?

An efficient distillation column is very tricky to set up, the head temperature is critical, for ethanol it needs to stay at around 175-180 degrees to boil off the alcohol and not the water, I distill methanol out of the glycerine byproduct from biodiesel production.
I use a PID temperature controller to control the heat at two points the pot temperature and the the head temperature where the distillate enters the condenser, the temperature changes as the process runs, so you either need to baby sit the still or use a PID type controller.
The inputs you need are your feed stock, controlled heat, and some type of chiller for your condenser.
That is why on moonshiners they have what they call the top, the middle and the bottom, the top is the purest because of the high alcohol content in the mash at the start of a run, the middle is less pure because there is less alcohol available and it carries some water with it.
The bottom is much less pure as the mash at this point contains far more water than alcohol.
There is a lot involved in making a consistent end product, and a lot of custom fabrication.
