[135] The “Machines for packing en masse” Co. Ltd. Berlin, have recently strongly recommended their “wrapping machines, for centres of any shape or consistency, which work automatically, that is to say, it is only necessary to heap the centres in continuous succession in the machine, when they are urged forward and wrapped in paper or other materials, being finally despatched out of the machine automatically. The wrappers may be simple or double, loose, or tight fitting.” Their employment in the packing of chocolate tablets is especially recommended.—And so the problem would be solved! Unfortunately I am in want of personal guidance, never yet having seen the machines in working order, and so not being able to submit any opinion as to their efficiency. Even if they are really able to deal with larger tablets, yet the more critical problem regards the smaller goods, especially in connection with the wrapping in tin-foil.
[136] Flour can be more easily blended than starch with the cacao mass, as the granules of starch are only with difficulty crushed.
[137] Recently in some inferior kinds of cocoa powder a quantity of oatmeal has often been added (up to 5 percent), causing the preparation to thicken when it is boiled with water.
[138] Still better, as less productive of dust, there being a less rapid circulation of air, and also not so wasteful, are the dismembrators as built by Paul Franke & Co.
