> Jeff, you described expected course of action for water. Please runthe still as supposed - with some alcohol in the water. I will behave
differently. You can get one gallon cheap wine and distill it. You
will see what will happen. Good luck and reduce a little the power of
the heating element. If you dont want to get into the power
controller field -- try a diode of corresponding power handling and
the voltage. It will cut the power.
- You'll be surprised at how much cooler the alcohol output will be as
compared to water. When distilling water the output is so hot it will
burn you, but when distilling alcohol the output is comfortably warm.
This is in the same still with the same heat input. Water takes lots
of energy to heat it, and requires lots of energy loss before it will
With a packed column, the temperature rise at the head is quite
sudden. You should be able to feel the 'hot spot' rising through the
column. You can leave your cooling water flow off until this hot spot
gets near the top of the column.
What is the size of the pipe connecting your double reducers? It
should be on the order of 1 inch. This should give you plenty of area
to allow the vapors to rise and the liquid to fall without any
gurgling. I use a single reducer style head with no noticable
gurgling. I can hear the liquid dripping off the condenser. Sounds
like running water, but not like bubbling.
What is the diameter of your column? I run 1500watts with a 2 inch
column with no problems. Perhaps the gurgling you hear is your column
flooding. Do you have the packing too tight? Can you easily blow
through the column?
When I distill water I run with no reflux and my output valve is fully
open. In this condition the output rate surges badly. I think this
is the result of the surface tension of water. It seems like the
water needs to build up before it will 'break over' and run down the
output tube. The still will 'spit' out half an ounce at a time. When
I distill alcohol I run with high reflux and the output valve is only
slightly open. In this condition there is a pool of alcohol in the
head which totally covers the output valve opening. There is no
surface tension effect and there is no surging.

============================Jeff,Motor controllers will burn out if used to control high wattage heater elements.What you need to be looking for is a cheap burst fire controller designed for the job.Have a look atAll the best,Mike N
