The stainless tank to the far left is the condenser, it has 120 foot of .75" copper tubing in a spiral configuration. The finished product comes out at 56 degrees F. The stainless tank mounted horizontally is the heater box, it has a 15 gallon rectangular heat exchanger inside. The mash is pumped into it with a pneumatic pump, as the still runs steam travels through the heat exchanger preheating the mash for the next run to about 150 degrees F. Once the mash in the still is done, one would empty the still, open the valve on the heater box to fill the still with preheated mash. The boiler injects stem into the mash via 2" copper tube with 38 holes in it. The steam travels out the still into the thumper barrel which is filled with 10 gallons of backings, then into the dry barrel, out of the dry barrel into the heater box where it exits into the condenser. An older gentleman runs the still by himself, it is just a matter of opening and closing valves.
On a different note I was thinking about visiting Tasmania, I would like to chat with you about that.
