Invention of "AN IMPROVED PROCESS FOR THE MANUFACTURE OF SUGAR,
WHICH INVENTION IS ALSO APPLICABLE FOR THE CONCENTRATION OF
MOLASSES."
PROVISIONAL SPECIFICATION left by the said Miguel de la Vega and Luiz
D'Oliveira at the Office of the Commissioners of Patents on the 4th December
1880.
MIGUEL DE LA VEGA and LUIZ D'OLIVEIRA, of the City and State of New
York, United States of America, Gentlemen. "AN IMPROVED PROCESS FOR THE
MANUFACTURE OF SUGAR, WHICH INVENTION IS ALSO APPLICABLE FOR THE
CONCENTRATION OF MOLLASSES."
This new and improved process for the fabrication of sugar and concentration of
molasses is substantially as follows:-
After extracting the liquid of the sugar-cane or the liquid of any other plant
or material now used in the fabrication of sugar, the liquid so produced is clarified
either in a hot or cold state by means of filtration. After being clarified the
liquid is placed in a suitable vessel or receptacle, and this vessel or receptacle is
placed in any suitable refrigerating apparatus, such for instance, as the apparatus
used in the well known "low pressure binary absorption system," and subjected to
freezing for the purpose of separating the sugar dissolved in the liquid from the
water of the liquid.
In practice we prefer to place the clarified liquid or sugar juice in a tin can or
vessel (preferably of circular form), and in any desired quantity, according to the
size of the refrigerating apparatus in which it is placed, and we subject the said
liquid to the freezing process. This will cause the water and sugar of the liquid to
separate, the water forming ice, and the sugar concentrating in the centre of the ice
so formed, and assuming the state or condition of a thick syrup.
When the syrup
so formed becomes so thick as to weigh from 41° to 43° Beaumé (specific gravity),

page_text: which is ascertained by testing, it is removed from the ice and dried, which is done
by subjecting it to treatment in the centrifugal apparatus for drying, or in the
vaporation apparatus, and it is dried to such a degree as may be desired. After
being subjected to this last process of drying it is ready for use.
By the freezing process above set forth sugar is made, which is superior in every
respect to the sugar made by the processes at present in use. Our improved process
is also more economical than any of those at present in use.
The same process
may be applied to molasses which has been made by any of the processes in
common use in order to concentrate the same, and diminish the volume thereof in
such degree as may be desired for purposes of facility and economy of trans-
portation.

MIGUEL DE LA VEGA and LUIZ D'OLIVEIRA, of the City and State of New
York, United States of America, Gentlemen. "AN IMPROVED PROCESS For the
MANUFACTURE OF SUGAR, WHICH INVENTION IS ALSO APPLICABLE FOR THE
CONCENTRATION OF MOLASSES."
Our improved process for the manufacture of sugar and concentration of molasses
is as follows:-After extracting the liquid of the sugar cane or the liquid of any
other plant or material now used in the manufacture of sugar, the liquid so
produced is clarified either in a hot or cold state by means of filtration. After
being clarified the liquid is placed in a proper vessel or receptacle, and this vessel
or receptacle is placed in any suitable refrigerating apparatus, such as the low-
pressure binary absorption system, or apparatus of refrigeration, and subjected to
the treatment of freezing for the purpose of separating the sugar dissolved in the
liquid from the water of the liquid. The process we prefer and which we have
found in practice to be best is as follows:-We place the clarified liquid or
sugar-juice in a tin can, preferably of circular form, and in any desired quantity,
having regard to the size of the refrigerating apparatus in which it is placed, and
subject the said liquid to the freezing process. This process will cause the water
and sugar of the liquid to separate, the water forming ice, and the sugar con-
centrating in the center of the ice so formed, and assuming the state of a thick
syrup. When the syrup becomes so thick as to weigh from 41° to 43° Baumé
(specific gravity), which is ascertained by testing, the syrup so formed is removed
from the ice and subjected to a drying process, which is done by subjecting it to
treatment in a centrifugal apparatus for drying or in an evaporation apparatus, and
the sugar is thus dried to such a degree as may be desired. After being subjected
to this last process of drying it is then ready for use. By our freezing process
above set forth sugar is made which is superior in every respect to the sugar made
by the processes at present in use. Our improved process is also more economical
than those at present in use. The same process may be applied to molasses which
has been made by any of the processes in common use, in order to concentrate
and diminish the volume thereof in such a degree as may be desired for purposes
of facility and economy of transportation.
Having thus fully described our said Invention, what we claim and desire to
secure by Letters Patent is,-
1. The above-described process for the manufacture of sugar, consisting in
separating the sugar from the water of the liquid by freezing the liquid and drying
the sugar, substantially as described.
2. The above described process for the concentration of molasses consisting in
freezing the molasses for the purpose of concentrating and diminishing the volume
of the same, substantially as described.
In witness whereof, we, the said Miguel de la Vega and Luiz D'Oliveira,
have hereunto set our hands and seals, this 18th day of April, in the year
