Description
FRANZ O. MATTHIESSEN, OF NEW YORK, N. Y.
IMPROVEMENT IN PROCESSES OF REFINING SUGAR.
Specification forming part of Letters Patent No. 162.243, dated April 20, 1875; application filed April 12, 1875.
CASE B.
To all whom it may concern:
Be it known that I, FRANZ O. MATTHIEssEN, of New York, N. Y., have invented an Improved Process of Refilling Sugar, of which the following is a specification:
My improvement relates to a modification of that process of refining sugar whereby the entire sugar-mass is converted into coffeesugar without leaving any fluid remainder in the form of sirup.
As I have invented several modifications in this process, for which I am about applying for patents, I shall, for convenience, designate the present application as Case B.
The modification of the process to which the present application refers includes the boiling of the clarified sugar-liquor in the vacuum-pan until the usual crystallization has taken place 3 but, instead of mechanically separating the crystals and reboiling the sirup, the entire contents of the vacuum-pan is discharged directly into shallow trays or pans, and, being thus divided into thin layers, is subjected to gentle heat in the open air, and a consequent prolongation of the processes of evaporation and crystallization, until nearly all the water contained in the material operated upon has been evaporated, and it has acquired the condition of a granular mass substantially like what is known as coffee-sugar, the slight portion of sirup present being adherent to the sugar-crystals. The heat of the sirup itself as it comes from the vacuumpan is thus utilized for the purpose of promoting evaporation, but an additional application of heat will usually be required to prevent the cooling of the sugar-mass and complete the operation. Care must be taken not to allow the temperature to exceed 212 Fahrenheit, and it is preferable to conduct the process to completion at a lower temperature than that.
The distinctive characteristic of the present invention is the immediate subjection of the divided sugar-mass discharged from the vacuum-pan to a process of gentle evaporation in the open air.
I claim as my invention- The improved process of refining sugar herein described, which consists, in addition to the ordinary boiling of the clarified sugarliquor in the vacuum-pan, in dividing the hot sirup and crystallized sugar discharged from the vacuum-pan into small masses or thin layers, and subjecting such small masses or thin layers to a process of gentle evaporation, conducted in the open air, and prolonged until sufficient water has been expelled from the material operated upon to convert it into a granular mass, as set forth.
F. O. MATTHIESSEN.
