The accompanying diagram of a chocolate factory is reproduced by kind permission of the Berlin publishers of Dr. Paul Zipperer's well-known work on "The Manufacture of Chocolate," which contains much valuable information. The machinery described is that of Messrs. Lehmann, of Dresden, one of the largest makers on the Continent.
By means of the lift (1) all the raw materials, sugar, cocoa, packing, etc., are carried up to the store-rooms (2). Here are the machines for cleansing and picking the raw cocoa-beans, which are fed into the elevator boxes (3) above the cleansing machine (4), which frees them from dust; they then pass to the continuous band (5) on which they are picked over, and from which they fall into movable boxes (6). They are thence transferred to the hoppers (7), and fed by opening a slide in the hopper, into the roasting machine (8). The quantity contained in the hoppers is sufficient to charge the roasting machine. When the roasting is completed the cocoa is emptied into trucks (9), and carried to the exhaust arrangement (10), where the beans are cooled down, the vapour given off passing out into the open air. At the same time the air of the roasting chamber is sucked out through the funnel-shaped tube fitted to the cover. The roasted cocoa is then passed to boxes (11), to be con-
