The course of manufacture of cacao powder is the same as in the manufacture of chocolate, up to the point where the cacao has passed through the crushing and cleansing machines (12). The broken beans are then taken by the elevator (27) to the machine for separating the radicles (28) and thence through the hopper (14) to the mills (15). The liquid cacao mass, passing from these mills, runs into the pans (29) from which as much required for charging the hydraulic presses as is can be drawn up by cocks. The accumulator (31) supplies all the presses with water. The pressed cakes are first put into the boxes of the frame (32). In an adjoining room is the automatic cacao pulverizing apparatus. It is fed through the preliminary crusher (34) from which the cacao is taken by the worm and elevator (35) to the pulveriser (36). The powdered cacao is then taken by a worm and elevator to the sifting machine (38). The sifted powder falls into the tub (39) while the coarser portion is carried back again to the pulveriser (36). The arrangements for treating and the disintegrating cacao powder can be provided in the manner already described. In both plans, the boiler and engine house are to be understood as placed in an adjoining building. FOOTNOTES: [236] Both are designs of the firm J. M.

Appendix Containing an account of the methods of preparation and the composition of some Commercial dietetic and other Cacao preparations. The following statements and recipes have no pretension to be complete; they are only introduced to serve as a brief summary of those commercial cacao preparations, now in commerce, which are mixtures of various kinds of substances with cacao or chocolate and are largely used for dietetic purposes. Notwithstanding its necessary incompleteness, the following account, which has been collected from various sources, will satisfy practical requirement, since the manufacturer, as well as the food chemist, frequently desires to obtain information at once, that even a complete technical library is not always able to supply. Medicinal chocolates have not been considered in the following list, since they belong to the province of pharmacy. =Acorn-cacao Michaelis’= contains according to an analysis by R.
