IMPROVEMENTS IN THE TREATMENT OF THE LOW OR POOR PRODUCTS OBTAINED IN THE MANUFACTURE OR REFINING OF SUGAR
Year: 1864

page_text: LETTERS PATENT to William Edward Newton, of the Office for Patents,
66, Chancery Lane, in the County of Middlesex, Civil Engineer, for the
Invention of "IMPROVEMENTS IN THE TREATMENT OF THE LOW OR POOR
PRODUCTS OBTAINED IN THE MANUFACTURE OR REFINING OF SUGAR."-A com-
munication from abroad by Eugène Bertholomey, of Rue St. Sebastien,
Paris, in the Empire of France.
Sealed the 8th November 1864, and dated the 30th May 1864.
PROVISIONAL SPECIFICATION left by the said William Edward Newton
at the Office of the Commissioners of Patents, with his Petition, on the
30th May 1864.
I, WILLIAM EDWARD NEWTON, of the Office for Patents, 66, Chancery Lane,
in the County of Middlesex, Civil Engineer, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN THE TREATMENT OF THE LOW OR
POOR PRODUCTS OBTAINED IN THE MANUFACTURE OR REFINING OF SUGAR," to be as
follows:-
The object of the present Invention is to extract at once and very quickly
all the product obtainable from the low or poor matters obtained in the manu-
facture or refining of sugar, and at the same time producing crystallization
during the baking. The necessity for many vessels, a large extent of space,
and much time for crystallization are obviated, and consequently much less
capital is required, added to which the grain of the sugar is better formed.
and larger, and the molasses are more easily separated from it.

page_text: These objects are effected by the following process-A part of the low or
poor matter is baked by the ordinary process in a sugar pan either in a
vacuum or not. This baked product, if left to itself, will at the expiration of
some time become crystallized. When this matter has arrived at this com-
mencement of crystallization the baking is continued in a vacuum pan, and
the crystals already formed are fed with successive supplies of syrup or
clarified sugar of the same nature. The commencement of crystallization
above mentioned may be effected in the apparatus which has served for the
first baking or, by preference, in a separate vessel. In any case the second
stage of the operation, which consists in feeding the crystals, must be con-
ducted in a vacuum, or in apparatus open to the air, and known as low
temperature apparatus. This improved process, which participates in the two
processes of crystallization now in use, therefore consists in charging a vacuum.
apparatus with matter which has been previously partially crystallized, as above
mentioned, or even with matter prepared with powdered sugar, or matters
completely crystallized and diluted with syrups, clarified or not, or water,
and the apparatus having been charged, working it by feeding the crystals
successively with clarified or other syrup.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Edward Newton in the Great Seal Patent Office on
the 30th November 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
EDWARD NEWTON, of the Office for Patents, 66, Chancery Lane, in the County
of Middlesex, Civil Engineer, send-greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by IIer Letters
Patent; bearing date the Thirtieth day of March, in the year of our Lord One
thousand eight hundred and sixty-four, in the twenty-seventh year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said William Edward Newton, Her special license that I, the said William
Edward Newton, my executors, administrators, and assigns, or such others as
I, the said William Edward Newton, my executors, administrators, and assigns,
should at any time agree with, and no others, from time to time and at all
times thereafter during the term therein expressed, should and lawfully
might make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Inven-
tion for "IMPROVEMENTS IN THE TREATMENT OF THE LOW OR POOR PRODUCTS

page_text: OBTAINED, IN THE MANUFACTURE OR REFINING OF SUGAR," being a communication
from abroad by Eugene Bertholomey, of Rue Saint Sebastien, Paris, in the
Empire of France, upon the condition (amongst others) that I, the said
William Edward Newton, by an instrument in writing under my hand and
seal, should particularly describe and ascertain the nature of the said Inven-
tion, and in what manner the same was to be performed, and cause the same
to be filed in the Great Seal Patent Office within six calendar months next
and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said William Edward Newton, do hereby
declare the nature of the said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement (that is to say) :-
It has long been the practice in sugar works and refineries to employ what
is called baking in the grain (that is to say) that by this process the crys-.
tallisation of the sugar and evaporation are effected simultaneously, but
this method of baking can only be applied to matters somewhat rich in sugar.
The crystallisation of the low or poor matters instead of being effected
during the baking is produced afterwards by leaving them to themselves
during a very long space of time in vessels of a capacity which is greater in
proportion as the matter is poor, and in localities which are kept at a high
temperature. This necessitates a large number of vessels and a large extent
of space, together with sufficient heating appliances also much time (say
several weeks), during which the substance must become deteriorated, and
large capital is required for these reasons. Besides this the crystals formed
are very small and difficult to separate from their syrup of crystallisation.
These syrups are therefore very rich, and require several bakings and crys-
tallisations before arriving at the extraction of the last products.
The object of the present Invention is to extract at once and very quickly
all the product obtainable from the low or poor matters obtained in the manu-
facture or refining of sugar, and at the same time producing crystallization
during the baking. By this means the inconveniences above enumerated,
viz., the necessity for many vessels, a large extent of space, and much time
for crystallization are obviated, and consequently much less capital is required,
added to which the grain of the sugar better formed and is larger, and the
molasses are more easily separated from it.
These objects are effected by the following process:-A part of the low or
poor matter is baked by the ordinary process in a sugar pan, either in a
vacuum or not. This baked product if left to itself will, at the expiration of
some time, become crystallized. When this matter has arrived at this com-

page_text: mencement of crystallization the baking is continued in a vacuum pan, and is
conducted in such a manner that during the process of evaporation the
crystals already formed are fed with successive supplies of syrup or clarified
sugar of the same nature. The commencement of crystallization above men-
tioned may be effected in the apparatus which has served for the first baking,
or, by preference, in a separate vessel. In any case the second stage of the
operation, which consists in feeding the crystals, must be conducted either in a
vacuum or in apparatus open to the air, and at a low temperature. This
improved process, which participates in the two processes of crystallisation
now in use, therefore consists in charging a vacuum apparatus with matter
which has been previously partially crystallised, as above mentioned, or even
with matter prepared with powdered sugar, or matters completely crystallised
and diluted with syrups, clarified or not, or water, and the apparatus having
been charged the working is to be continued by feeding the crystals
successively with clarified or other syrup.
In witness whereof, I, the said William Edward Newton, have
hereunto set my hand and seal, the Thirtieth day of November, in
the year of our Lord One thousand eight hundred and sixty-four.
