. Cane sugar; a textbook on the agriculture of the sugar cane, the manufacture of cane sugar, and the analysis of sugar-house products. th an arrangement of twelve knives is shown in Fig. fixed to the cover are one, two or more hoppers a into whichare fed the canes, which descend on to the disc by their own weight. Ahigh speed is given to the disc, from 100 to 150 revolutions per minute,and the knives cut the cane into chips one-twentieth of an inch or morein thickness, dependent on the setting of the knives. The hoppers aremade either vertical or at an angle—the former giving round and the latteroval chips. The chips fall into the receptacle formed by the sides ofthe apparatus below the disc, and thence pass on to the shoot. The cutteris variably placed above or below the diffusion battery. Cane cutters of thistype differ in details. They are sometimes directly driven without theinterposition of belt gearing, and are sometimes over instead of under-drivenas shown in Fig. 150. The shoot i is also sometimes dispensed with and itsplace taken by a scraper actuated by the shaft b. In this case the bottom of. Fig. THE DIFFUSION PROCESS 253 the receptacle h is flat, or nearly so. and the chips are swept out throughan opening in the bottom. To work up 300 tons of cane in 24 hours, a plant of this nature will beabout 5 ft. in diameter. The capacity depends on the number of hoppers,and on the setting of the knives, whether to give thick or thin chips. Morecane can be cut when thick chips are allowed, but the efiiciency of the after-process of diffusion is diminished. Diffusion Cell.—A section through a cell of a diffusion battery, alongwith its accompanying juice heater, is shown in Fig. 152. It consists of acjlindrical vertical shell, the bottom, being made ^\dth a slight slope, and thetop fitted with a head box ; the cell is closed by a door on the top, which isclamped tight by the screw and lever shown at 6 ; by slackening the screwthe door can be slung o
