RICHARD MACDONALD, OF NEW ORLEANS, LOUISIANA.
IMPROVEMENT IN PROCESSES FOR BLEAEHING AND IMPROVING COTTON-SEED OILS.
Specification forming part of Letters Patent No. 1 89,867, dated April 24, 1877; application filed October 16, 1876.
cess for Bleaching and Improving Cotton- Seed Oil and I do hereby declare the following to be a full, clear, and correct description of the same.
This improved process relates more especially to the treatment of that class of cottonseed oil which is known to commerce as the summer yellow oil.
In order to whiten and otherwise improve the said oil, as well as to render it unaffected by cold, the practice heretofore has been to subject the same to what is termed the winter straining'processthat is to say, the oil is frozen, or at least reduced in temperature until partially solidified, when it is strained through cloths, or other material, to separate from it the stearinecontained'thcrcin. By the said process the quantity of oil is materially reduced, and, as the stearineis, comparatively speaking, of butlittle value, the manufacturer is rewarded with but little profit.
The object of my invention is to produce from the abovementioued materials, without removing the stearinc therefrom, an oil for table or other use, of delicate flavor and color, which will not in any. manner he afi'ected by cold, or a changing temperature and my proize the oil, and leave it in a limpid state, fit
for table, burning, or other use.
The rationale of my process, it is believed, consists in breaking up the stearine into other hydrocarbons, which remain fluid at temperaturesswhich would effect the solidification of the stearine.
Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-
The process herein described of bleaching cottonseed oil and improving its quality, thesame consisting in heating it to about 300 Fahrenheit, and maintaining it at that temperature for about three hours, substantially as described, and for the purpose set forth. RIGHARI) MACDONALD. Witnesses:
J. T. HARE, I J. O. HUBBELL.
