The fireside university of modern invention, discovery, industry and art for home circle study and entertainment . the vessel into which the clarified juice flows. It is avacuum, but not a pan, for the vessel is spherical, with coppersteam coils in the bottom. A glass window permits the liquidto be seen, and electric lights make the interior still more plainlyvisible. An air-pump and condenser remove the air, and thejuice boils with less heat than two hundred and twelve degreesand with more agitation than in the open air. When the mole-cules of Sugar begin to form into crystals, the charge is dumpedinto the mixer. What is the Mixer ? It is a long trough, in which a shaft revolves. On the shaftare steel arms that play in the Sugar, beating the crystals apart,and bringing them near other molecules still unattached. Whenthe grain or crystal is of the right size it goes to the centrifrugal. What is the centifrugal machine ? The principle is the same as in the cream-separator and theflour mill. A kettle-shaped vessel in which the wet sugar isplaced, revolves twelve hundred times a minute. Its sides are. Fig 114. CENTRIFUGAL SUGAR MACHINES. lined with brass gauze. The thin parts of the Sugar are heaviest,and they fly upward to the gauze, and outward in the form ofmolasses. Remaining in the kettle is dry, white Sugar, which 300 THE FIRESIDE UNIVERSITY. is the sweet Coffee A of our tables. It is a better Sugar in manyrespects, but does not compete with the popular granulatedSugar of the great refineries. Describe the Sugar Refineries. Hogsheads of Muscovado (word from the same root as Mis-chief), meaning unripe or unfit Sugar together with molasses,arrive in vast quantities. The material goes to the top floor,where it is dissolved in water and boiled in pans or blow-ups
