Thesheer is a large steel cylinder inwhich the beets are cut into longslender strips called cossettes. Thecossettes are carried in an iron trough to the diffusion battery,which consists of from twelve to fourteen steel tanks or cells,each holding about two and one half tons of cossettes. The sugar is dissolved out of the beets by a stream ofwarm water, which enters at the top of one cell, passesdown through the mass of cossettes, up through a heatingtube, and down through the next cell. The juice is pipedfrom the diffusion battery to the measuring tank. Whenthe sugar has been extracted, the remaining pulp is pumpedto the silo and is used for feeding cattle and other live Figure 175.—Centrifugal machinesin a sugar factory. SUGAR AND FLOUR 383 Purifying the Juice. The juice that accumulates in themeasuring tank is a dark-colored, sweet liquid containing ahigh percentage of sugar mixed with various of lime is added to the juice which absorbs a vastquantity of the impurities suspended in the liquid. Carbondioxide, now added, unites with the dissolved portion ofthe lime, forming a white insoluble substance which settles,carrying with it much of the dark-colored matter. The liquid is then pressed through canvas filters to sep-arate it from undissolved lime and dark-colored processes are repeated for further purification. Sulphur is burned and the gas produced, known as sul-phur dioxide, is passed into the juice. This combines withthe lime in the solution, forming insoluble compounds whichare removed by filtering through canvas. Concentration. The liquid is now concentrated by boil-ing off a part of t
