The liquor is boiled in A and the vapors pass off into the worm B, which is surrounded by the cold water of the condenser, the distillate being drawn off at f.
The heated vapors passing through the worm B will soon heat up the water in C thereby retarding perfect condensation. To prevent this, a cold water supply pipe may be connected to the bottom of C making a connection at the top of C for an over flow of the warmed up water. By this means the lowest part of the worm will be kept sufficiently cool to make a rapid condensation of the vapors.
Fig. 6.—A Simple Still.
The boiler A can be made in two parts; the upper part fitting into the lower part snugly at d. The pipe from the upper part fitting the worm snugly at e. This will enable the operator to thoroughly cleanse the boiler before putting in a new lot of liquor. The joints at e and d should be luted with dough formed by mixing the flour with a small portion of salt and moistening with water. This is thoroughly packed at the junctions of the parts to prevent the escape of steam or vapor.
