[113] The determining of the fibre is reached by the Weender method. [114] For that purpose boxes with handles and having a capacity of from 10½ to 60 litres are employed, as well as the portable troughs previously mentioned. The transport of the chocolate mass also takes place in boxes made of compressed steel plates (Siemens-Martin), galvanised or otherwise, e. g. as manufactured by the Stamp and Press Works at Brackwede near Bielefeld. The firm of A. Reiche and others also make similar boxes. [115] Muspratt Encyclop. Handbuch der techn. Chemie. Vol. IV, p. 190, 1902. [116] This description is taken from Muspratt, Encycl. Handb. d.

[120] Should such rooms eventually be insulated, the best material for this operation are “Corkstone Plates”, as manufactured by various firms (e. g. Korkstein-Werke Coswig i. Sa., etc.). [121] This extensive employment of cacao butter in the preparation of covering material on the one hand, and on the other the consequently increased cost of chocolates rich in fat, have hitherto proved the chief objection to the preparation of cocoa powder deficient in fatty contents, which we shall discuss later.

[130] The potash now generally in use is prepared from the carbon of residuary molasses, and is technically considered, very pure. It is supplied by Dr. Hensel & Co., Blumenthal (Hanover). [131] The special model of the Universal Mixer and Kneader has for this purpose (apart from the metal lid shutting down air-tight) a steam drain pipe, which is fitted with a ventilator and led into the open, so that the vapours and chemical exhalations can escape without causing any damage.
