An Improved Process of Producing Refined Sugar from Raw
Sugar.
I, NICOLAS TSCHERIKOWSKI, of Smiela, in the Empire of Russia, Civil Engineer,
do hereby declare the nature of this invention to be as follows:-
The object of this invention is to produce refined sugar direct from well cleaned,
white and also from ordinary yellow raw sugar, thereby rendering it unnecessary to
dissolve the sugar to be refined, to filter the refining juices or to evaporate them, and
when using well cleaned white sugar the claying of the refined sugar by means of
cleare is avoided and the browning or burning of the sugar is prevented.
With well cleaned white raw sugar this is effected in the following manner :-
The raw sugar to be refined is converted as quickly as possible into a hot liquid
mass or pulp by means of steam, advantageously in a mixing apparatus, it is then
caused to run into moulds in this condition and is cooled down whereby the sugar is
prevented from assuming the state of caramel.
The liquid mass or pulp filling the moulds in cooling sets into a compact crystalized
mass of sugar which has only to be freed from the white syrup situated between the
crystals by means of centrifugal machines, or by steam, by suction-pipes, or by
compressing machines, and the refined sugar is then dried.
For this purpose it is advantageous to employ a mould open only on one side and
closed at the top, and trucks or other similar means are employed in which the moulds
are continually cooled by water.
It is obvious that the moulds can be of any required form so as to produce sugar in
various shapes.
The production of refined sugar direct from ordinary yellow raw sugar is effected
in the following manner :-
The yellow raw sugar to be refined is, as before described, converted as quickly as
possible into a hot liquid mass or pulp by means of steam, advantageously in a
mixing apparatus, after which the said mass or pulp is caused to run into moulds and
is rapidly cooled. The mass or pulp filling the moulds in cooling sets in a compact

out by means of cleare.
For claying with the cleare it is advantageous to employ claying apparatuses in
which the cleare is introduced into the mass of sugar from the pointed end of a
conically-shaped mould and in which consequently the syrup flows out of the larger
end of the mould.
After this the cleare between the crystals is forced out by means of centrifugal
machines, by steam, by suction-pipes, or by compressing machines, after which the
refined sugar is dried.
The openings at the pointed ends of the moulds employed are closed with stoppers,
if the cooling of the mass of sugar is effected by means of water.
It is obvious that in this case also the shape of the moulds can be varied.

Sugar.
I, NICOLAS TSCHERIKOWSKI, of Smiela, in the Empire of Russia, Civil Engineer,
do hereby declare the nature of this invention and in what manner the same is to
be performed to be particularly described and ascertained in and by the following
statement:-
The object of this invention is to produce refined sugar direct from well cleaned,
white and also from ordinary yellow raw sugar, thereby rendering it unnecessary to
dissolve the sugar to be refined to filter the refining juices or to evaporate them, and
when using well cleaned white sugar the claying of the refined sugar by means of
cleare is avoided and the browning or burning of the sugar is prevented.
With well cleaned white raw sugar this is effected in the following manner :-
The raw sugar to be refined is converted as quickly as possible into a hot liquid
mass or pulp by means of steam, advantageously in a mixing apparatus, it is then
caused to run into moulds in this condition and is cooled down whereby the sugar is
prevented from assuming the state of caramel.
The liquid mass or pulp filling the moulds in cooling sets into a compact crystallized
mass of sugar which has only to be freed from the white syrup situated between the
crystals by means of centrifugal machines, or by steam, by suction-pipes, or by
compressing machines, and the refined sugar is then dried.
For this purpose it is advantageous to employ a mould open only on one side and
closed at the top, and trucks or other similar ineans are employed in which the moulds
are continually cooled by water.
It is obvious that the moulds can be of any required form so as to produce sugar in
various shapes.
The production of refined sugar direct from ordinary yellow raw sugar is effected
in the following manner :-
The yellow raw sugar to be refined is, as before described, converted as quickly as
possible into a hot liquid mass or pulp by means of steam, advantageously in a
mixing apparatus, after which the said mass or pulp is caused to run into moulds and
is rapidly cooled. The mass or pulp filling the moulds in cooling sets in a compact
mass of crystallized sugar from which the syrup situated between the crystals is drawn
out by means of cleare.
For claying with the cleare it is advantageous to employ claying apparatuses in
which the cleare is introduced into the mass of sugar from the pointed end of a
conically-shaped mould and in which consequently the syrup flows out of the larger
end of the mould.
After this the cleare between the crystals is forced out by means of centrifugal
machines, by steam, by suction-pipes, or by compressing machines, after which the
refined sugar is dried.

if the cooling of the mass of sugar is effected by means of water.
It is obvious that in this case also the shape of the moulds can be varied.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is :-
1. The herein described process of producing refined sugar from white (clean) raw
sugar consisting in the rapid transformation of the said sugar into a hot liquid mass
or pulp, which mass or pulp is then caused to run into moulds of various shapes and is
cooled down therein, whereby the said mass or pulp sets in a compact crystallized
mass which has only to be freed from the syrup situated between the crystals and to
be finally dried.
2. The herein described process of producing refined sugar from yellow (imperfectly
cleaned) raw sugar, consisting in the rapid transformation of the said sugar into a
hot liquid mass or pulp, which mass or pulp is then caused to run into moulds of
various shapes and is cooled down whereby the said mass or pulp sets in a compact
crystallized mass, from which the syrup situated between the crystals is afterwards
withdrawn by means of cleare, after which the adherent crystallized cleare is removed
and the refined sugar dried.
