The following description and figures will give a correct idea of the apparatus and its mode of working. Rillieuxs boiling apparatus is composed of three or four pans. The four-pan apparatus.—The cane-juice, after having passed the clarifiers and niters, flows into avat, from which it is pumped in the first pan A, through a pipe a, Fig. 3385, which leads to the backpart of that pan, on which pipe there is a stop-cock, which is opened or closed by means of a handle bplaced in front of the apparatus, where the man who manages the apparatus is placed; and, in turning. that handle more or less, he can regulato the feeding of that pan, in front of which is 0 pipe (•. Pigi8383 and 3385, leading the cane-juice to the back part of the second pan 1>; on that pipe and under ih*first pan is a stop-cock, worked by the hand </, by which the feeding of the second pan 1? is regulatedand in the front, on this second pan and below, is another stop cock, worked by the hand 9 : from thaistop-cock a pipe e leads to the back of pan 0, to convey the cane-juice, now at the density of LB0Beaume\ into said pan; and from this pan a pipe leads to a pump which draws the syrup, now arrivedat 28°, from the pan c, and forces it up to the dariiiors K E. In those clarifiers the syrup is heated upto the boiling point and scummed; from thence it passes through the bone black tillers (,; t;, whence itgoes to a vat H, Fig. 3381, below, to supply the fourth or strike pan D.
