The best method of boiling two, three or more Stills or Kettles with one fire or furnace.
This method has been found to answer in some instances, and may perhaps do generally if properly managed. I will here give the result of my own experiments.
I set a singling still holding 180 gallons on a furnace of 18 by 14 inches, and 4 feet six inches long, with the bottom to the fire, she had a common head and worm with scrapers and chains in her. I extended the flue, (or after passing it round her), to the doubling still which it likewise went round—but to prevent too much heat from passing to the doubling still, I fixed a shutter in the flue of the singling still, immediately above the intersection of the flue of the doubling still, to turn all the heat round her, and another shutter in the flue of the doubling still at the intersection of the flue of the singling still, to shut the heat off from the doubling still if necessary.[Pg 100]
With this fixture I run six hogsheads off in every twenty four hours and doubled the same, with the same heat and fire. I likewise had a boiler under which I kept another fire, which two fires consumed about three cords and an half of wood per week, distilling at the rate of sixty-five bushels of grain per week, and making about one hundred and ninety gallons in the same time.
Before I adopted this method I kept four fires agoing, and made about the same quantity of whiskey, consuming about four and an half cords of wood per week, and was obliged to have the assistance of an additional distiller per week.
I have since heard of the adoption of this plan with more success than I experienced.
