Description

UNITED STATES PATENT OFFICE.
ISIDOR KITSEE, OF PHILADELPHIA, PENNSYLVANIA.
BLEACHING SUGAR-JUICE.
SPECIFICATION forming part of Letters Patent No. 637,004, dated November 14, 1899.
Application filed June 1, 1899. Serial No. 718,969. (No specimens.)
To all whom it may concern.-
Be it known that I, ISIDOR KITSEE, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Clarifying or Purifying and Decolorizing of Sugar, which improvement is fully set forth in the following specification.
My invention relates to an improvement in the manufacture of sugar and the refining of the same; and it consists in subjecting sugar solution to the successive actions of an active agent, which decolorizes the solution, and a passive agent,which removes said active agent, the latter thus being no longer present in the.
sugar.
In carrying out my invention I take either sugar-j nice or sugar otherwise in solution and place it in a suitable tank or reservoir. I then introduce chlorine gas, preferably under pressure, into the reservoir, so as to subject the solution to the action of the same, whereby the solution is changed in color from brown to one that is pure White or nearly, and so is comparatively bleached. Olefiant gas, preferably under pressure,-is now introduced into the reservoir and the solution is agitated and preferably raised to a higher temperature. This gas, which is the product of distillation of hydrocarbon oils, has a great affinity for the chlorine gas. The product of the combination of the gases is insoluble in said solution and forms an oily substance, which rises to the surface of the solution, and the same may be removed by skimming or other means, the solution thus being divested of the objectionable chlorine gas. I
Having thus described my invention, What I claim as new, and desire to secure by Letter Patent, is
1. The process of treating sugar solution, which consists in first subjecting the solution to a bleaching agent and next, to olefiant gas.
2. The process of treating sugar solution which consists in first subjecting the solution to a' bleaching agent and next to a hydrocar bon gas. t
3. The process of decolorizing sugar solu tion, which consists in subjecting the solution first to the action of chlorine gas to bleach the same and next to the action of an olefiant gas which removes said chlorine gas.
4.. The process of treating sugar solution,
which consists in first subjecting the solution to the action of a bleaching agent and next subjecting said solution to the action of an agent capable of uniting with said bleaching agent and forming a compound insoluble in said solution and thereby removing the same out of the solution.
In testimony whereof I sign my name, in the presence of two subscribing Witnesses, this 12th day of May, A. D. 18.99.
ISIDOR KITSEE.
