Description

Patented Dec. 16, 1930 UNITED" STATES PATENTOFFICE SOCIETE ANONYME, F TIRLEMONT,-BELGIUM, A
oonrona'rrou CURING MASSECUITE No Drawing. Application filed February 11, 1927, Serial No. 167,595, and in Germany July 24, 1926.
Green sugar or massecuite was formerly boiled, so that it left the boiling apparatus in a more or less still liquid state. It was cooled in tubs, but only to the extent so that it left these tubs still in the liquid state. If the massecuite showed atendency to lose 'this state, syrup or even water was added in order to maintain the mass in a sufliciently liquid condition, so that the crystals could i be separated from the mother liquor in centrifuges of known construction in which the centrifugal force amounted to 800 times the weight of the mass to be separated.
With the continued cooling in the cooling tubs, the yield of sugar increases; it is found by experience that this is also the case if the massecuite loses the liquid state and passes over into a pasty or plastic condition; Also,
the yield can be still further increased if the a massecuite during or after cooling is deprived of a portion of its water content, for example by evaporation'or the like. A massecuite of pasty orlastio condition cannot be worked in centri uges of known construction. Experiments have now ployment of especially high centrifugal force (over 800 times the weight of the centrifuged mass) the pasty or plastic masses can be separated into sugar crystals and syrup more efiiciently and purer crystals are obtained than were possible with liquid massecuite and the use of centrifugal forces of usual amount.
I claim: a 1. A process for increasing the yield of sugar crystals from any kind of massecuitewhich comprises boiling the massecuite, 0001-.
ing to a pasty condition, and then separating' the mass into sugar crystals and syrup b means of a-centrifuge, in which the centri ugal force is considerably more than 800 times the weight of the mass to be separated. 2. A process for increasing the yield of sugar crystals from any kind which comprises boiling the massecuite, cooling to a pasty condition, removing a portion of its water content, and then separating the mass into sugar crystals and syrup by means of a centrifuge operating under a high cenof the mass to be separated.

trifugal force of atleast 800 times the weight g 3. A process for increasing the yield of sugar crystals from any kind'of massecuite which comprises boiling the massecuite, cool ing to a pasty condition, removing a portion of its water content by evaporation, and then separating the mass into sugar crystals and syrup by means of a centrifuge in which the centrifugal force is considerably more than 800 times the weight of the mass to be separated.
4. A process for increasing the yield of sugar crystals from massecuite which comprises increasing crystallization by bringing the massecuite to a pasty condition, and then separating the mass into sugar crystals and syrup by-means of a centrifuge, in which the centrifugal force is considerably more than 800 times the weight of the mass to be separated.
In testimony whereof I have aflixed my signature.
