3D model of the AT fractionating column. The fractionating column is open at the top and fitted with 2 valves. The valves are opened to prevent the buildup/condensing of volatiles. When the correct temperature is reached (77-78°C) it is closed. The bottom valve is closed until the correct temperature is reached (77-78°C) so as to heat up the container more rapidly.
The condensor used is a jacketed condensor.
The fractionating column is heated electrically (kept perfectly at 77-78°C)
Note that besides this equipment, it is vital to first make a good brew in order to efficiently make ethanol. Ethanol is useful for several things: ie ie as a fuel, sterilising agent, liquid for food conservation, ...
