A practical handbook on the distillation of alcohol from farm products, including the processes of malting : mashing and mascerating : fermenting and distilling alcohol from grain, beets, potatoes, molasses, etc., with chapters of alcoholometry and the denaturing of alcohol ... . produced against the firstcylinder by the elasticity of the principal clothon which it is borne. Then, encountering a seriesof four little rollers, perfon ling the functions ofthe preparatory press, it is next seized betweenthe second and first cylinders, and deprived of themaximum quantity of juice. Dujardins roll press is shown in Fig. 49, whichis a vertical section of the machine, the side platebeing removed. The pulp is forced upward througha pipe C under high pressure. This has a regulatingslide valve D. The rolls B B revolve towards andnearly in contact with each other, and they areperforated so that the expressed juice may run offthrough the rolls. These perforations are conicalin form with the apex of the cone outward. Thecylinders are also covered with a webbing of clothor horse hair. Below the rolls is block C, whichwith the outer walls of the chamber, form di-verging passages which extend upward, as shown,on either side of the rolls and then downward ALCOHOL FROM BEETS. 155.

The pulp is compressed with greatforce against and between the rolls, the juice isforced through the perforations and the residuepasses upward and outward under the presser barE in the form of a ribbon which is guided awayby the trough F. The pressure of the bar E isregulated by screws and the tighter said bar ispressed against the rolls the greater will be thepressure of the pulp behind the bar and against therolls, and the greater the juice expressed. The rolls revolve very slowly only about sevenor eight times a minute but the capacity of themachine is very great, it being capable
