IMPRGVEMENT IN PROCESSES GF GRANULATING SUGAR.

Specification forming part of Letters Patent No. 132,511, dated October 22, 1872.

.and State of Tennessee, have invented a new and Improved Process for Granulatin g Sugar, of which the following is a full, clear, and exact description The said process is as follows: We run the juice from the mill through white clay or fine white sand, whereby all the fibers or particles of cane are caught. It is then conveyed in pipes to the settling-box, from which it is let onto the first section and front end of the evaporator, where it is heated to boiling and skimmed off. It is then passed to the second section and boiled to about 25 density, or sweet; thence to the third and finishing section. When this is reached we add about one pint of tannin (made preferably from white oak, the liber or inner bark being taken off) to each gallon of sirup. As the tannin is added the glutinous and feculent matters are separated from the saccharine, brought to the surface, and thrown off, leaving the sirup a clear golden yellow color. The boiling is continued until 36 density, or sweet, is attained, when machine, which separates and dries it at the I same time, and a continued practical test has demonstrated that about five pounds of sugar to each gallon of sirup can be realized with a residuum of six pounds of good sirup.

Having described our invention, we claim The process herein described for granulating sugar.

In testimony whereof we have hereunto signed our names.

WILLIAM YOUNG. WILLIAM BOSSON.
