The apparatus designed by the writer for the purpose, and THE DETERMINATION OF CANE SUGAR 501 which differs only in details from that employed by Spencer, to whom theroutine is due, is shown in Fig. 332. A is a cylindrical container 6 by 10 ins. high, provided with a wdde flange B at the top and per-forated at the side near the bottom as indicated at C. D is a cylindricalvessel with a flange E corresponding to the flange B. At the bottom ofthis container is located a hot element, F, which may be either a steamcoil, or an electrically heated resistance. The bottom of the vessel D isperforated. Across the top of the bagasse container is laid a cover G, inwhich is inserted a tube PI, allowing of connection to a source of three parts B, E, and G may be drawTi together by means of clamps K,and a tight joint secured. On making connection to the source of vacuum,a current of hot air following the direction showoi by the arrows is aspirated. Fig. 334 through the bagasse. The size of container given will hold 1,000 grams ofbagasse and drying wiirbe complete in two hours. Vacuum Oven.—The vacuum ovens usually found in sugar laboratoriesare essentially of the pattern devised by Carr*. They are obtainable fromdealers, but more conveniently and at less cost can be constructed in thefield. One made by the \\Titer is shown in section in Fig. 333, while aperspective view is given in Fig. 334. It consists of a piece of 6-inch copperpipe 9 inches long. A chamber h is arranged round the pipe, into whichis conducted exhaust steam, the condensed water being carried away bythe pipe c. The vacuum chamber of the oven is connected to the last ceUof the evaporator by a half-inch pipe d. The door of the oven is astiff iron or steel plate h, on which is arranged a washer of some softmaterial such as asbest
