Sor′ghum-e-vap′o-ra-tor.
A furnace with pans for boiling the expressed juice of the sorghum or imphee.
Fig. 5313 shows an apparatus consisting of a series of filters and pans.
The juice is first purified in the filters
A C, passes to settling-troughs, is conducted by pipes to the pan
G, where it is brought to a boil, passed through a hot filter, and thence to pans
I K L M in succession, by which it is condensed.
Figs. 1888,
1889,
1890, pages 812, 813, show evaporators with pans in succession and in steps; also a rocking-pan with a sinuous track for the juice.

Sorghum-evaporator. |
Fig. 5314 shows an arrangement of pans on carriages by which they may be brought into the required position or succession over the furnaces.
Each evaporating-pan is pivoted to a truck, by which it may be moved along tracks from one furnace to another, or from the place of filling to that of deposit.
The supporting casters may be turned 90° to allow of running over all portions of the rectangular track.
The pans may be tilted to discharge their contents.

Pan and self-skimming arrangement. |
In
Fig. 5316, an outside filtering pocket is filled with wool: as the juice boils over, it cools and sinks in this pocket, and reaches the pan again, parting with the scum and feculencies which are retained by the wool.
This keeps up a continued circulation and straining process.
