FIPEEEOB )(R UHIIUH u: mi it a diluted fitting T. CHALKLEY TAYLOR, OF PHILADELPHIA, PENNSYLVANIA.
/ Letters Patent No. 94,359, dated August 31, 1869; 'antedated August 20, 1869.
IMPROVED MODE OP BLEAC HING- GRANULATED SUGAR.
The Schedule referred to in these Letters Patent and making part at the same- To all whom it may concern sugar after granulation, bysubjecting it to the fumes of burning sulphur, or a mixture of carbonic-acid gas i and sulphurous gas, as may be desired.
I am aware that apatent was granted on the 6th day of December, 1859, for a method of bleaching or whitening sugar, by exposing it while'in a liquid state in a boiler or wit, to the action of sulphurous-acid gas, which was forced through perforations made in a pipe or pipes that were arranged at the bottom of the vat, 1 do not therefore claim as my invention this method of treating sugar while in aliquid state and during defecation. l
My improved process ofbleaching is conducted as follows:
I take, say, lifty pounds of raw or granulated sugar, and spread it loosely upon the floor of a close apartment,- or it may be spread upon the surfaces of shelves, composed of fine gauze, or reticulated work, arranged in a close room, so that the gas or gases used for bleaching can circulate freely over and through them.
\Vhile in this condition, 1 subject the sugar to the bleachingaction of sulphurous-acid gas, which is caused to fill the 'room' containing the sugar.. During this bleaching process, the sugar may be frequently-stirred or agitated, to allow the gas to act equally upon the entire mass.
If desirable, the furnace in which the sulphur is heated may be placed in the apartment with the sugar, or the gas may be produced outside of the apartment and conducted therein through pipes or' tines.
To facilitate the combustion of the sulphur, charcoal may be turned with .it, which-will aflbrd carbonicacid gas, that will also assist in the bleaching-process.
The proportions are about one pound of sulphur to about fifty pounds of sugar, and the time consumed in theprocess will be about thirty hours, or until the necessary degree of bleaching has been attained.
Having described my invention,
What I claim as new, and desire to secure by Let'- ters Patent, is-
The method herein described of bleaching granu lated sugar.
Witness my hand in the matter of my application for a patent for improved mode of treating sugar.
