"IMPROVEMENTS IN THE MANUFACTURE OF SUGAR."
It is well known that the sugar contained in molasses and syrups can be deposited
in the form of a precipitate of sugar baryta by means of caustic baryta according to
the process of Dubrunfaut. The sugar baryta so obtained has hitherto been rendered
into sugar by itself by decomposing it by means of carbonic acid, and separating
the resulting carbonate of baryta from the liberated sugar solution.
Now according to this present Invention I utilize the sugar baryta for the
separation or decomposition of beet root juice or other vegetable juice instead of
rendering it into sugar directly, in other words I separate the baryta from the sugar
baryta not by means of carbonic acid, but by means of non-sugary and depositablo
parts of the beat or other vegetable juices. In this process the sugar liberated from
the sugar baryta combines with the sugar of the separated bect or other vegetable
juice, and these masses of sugar are then together rendered fit to be run into the
mould in the ordinary way.
The juices resulting from this method of separating the beet juices are materially
purer than those resulting from the lime treatment because the baryta deposits a
large number of non-sugary materials of the beet juices which are not removed by
the lime treatment. The juices from the baryta separation may even be treated
immediately after saturation with carbonic acid and the complete removal of the
baryta without first filtering them by means of animal charcoal.
In order to separate the beet juice (and other vegetable juices which I for
shortness sake hereinafter omit), by means of sugar baryta 1 put this latter in excess
quantity directly into the juice, and boil. The baryta slime of separation thereby
produced may during or after its production at once be treated with carbonic acid

page_text: in order to remove the larger part of the excess of the baryta and to take away the
gelatinous consistency from the slime by the admixture of carbonate of baryta.
During this separation with simultaneous saturation the carbonic acid may to a
limited amount be introduced, in order that the juice may retain a strong baryt-
alkality which is only done away with after the slime has been removed by means
of a second or secondary saturation.
It is advantageous first to mix the sugar baryta required for the separation of a
given quantity of beet juice with a small quantity of such juice stirring it into a
milky consistency or "milk" and while stirring to pour it into the heated main
bulk of the beet juice. During the subsequent boiling I then let in the carbonic
acid until the separation is completed.
The baryta slime of separation including the slime of saturation contains
coagulated albuminous substances and also all the inorganic and organic non-sugary
materials deposited from the beet juices, also carbonate of baryta. When this
latter has been removed or washed out of the juice by the filter press or otherwise
it must be subjected to a special treatment for recovery of the baryta contained
therein. This consists in forming the slime at once or after drying and with or
without admixtures such as sawdust, smalls of coal, tar or the like, into bricks or
pieces which are dried and made glowing hot in a furnace. Or the dried slime
inay first be dry distilled in retorts for the purpose of obtaining the ammoniac, tar
and combustible gases for heating and lighting purposes, and the residue remaining
in the retorts are then first together with the aforesaid mixture made into bricks.
In the glowing of the slime the organic acids, the albumen, the pectine and the
like as well as the admixtures (if any) are first burnt, and the carbonate of baryta
produced will by the further glowing be converted into caustic baryta. The always
small quantity-of-sulphate-of-baryta-is-transformed into sulphide of barium, while
the other inorganic slime parts such as phosphoric acid, iron and manganese remain
unchanged.
The slaking and manipulation of the caustic burnt baryta bricks is done according
to the known methods, whereby is obtained firstly crystallized hydroxide of barium
Ba(OH), SH, O, and secondly an undissolved remainder, consisting mainly of
unchanged carbonate of baryta and also contains the aforesaid parts (phosphoric
baryta, iron, manganese and the like).
The crystals of baryta Ba(OH), + 8HO serve again to separate the sugar
from the molasses according to Dubrunfaut's process; the saccharate of baryta
obtained thereby is then as stated again applied to the separation of the beet juice,
and so on.
The aforesaid remainders from the slaking of the caustic burnt slime of separation
are collected and periodically once more made into bricks in the manner described,
made glowing hot and so on, whereby a further amount of crystals of baryta are
obtained. The remainder froin this second brick manufacture may if required be
treated in like manner or else thrown away.

PROVEMENTS IN THE MANUFACTURE OF SUGAR.
It is well known that the sugar contained in molasses and syrups can be deposited
in the form of a precipitate of sugar baryta by means of caustic baryta according
to the process of Dubrunfaut. The sugar baryta so obtained has hitherto been
rendered into sugar by itself by decomposing it by means of carbonic acid and
separating the resulting carbonate of baryta from the liberated sugar solution.
Now according to this present invention I utilize the sugar baryta for the
separation or decomposition of beet root juice or other vegetable juice instead of
rendering it into sugar directly in other words I separate the baryta from the
sugar baryta not by means of carbonic acid but by means of non sugary and
depositable parts of the beet or other vegetable juices. In this process the sugar
liberated from the sugar baryta combines with the sugar of the separated beet or
other vegetable juice and these massos of sugar are then together rendered fit to
run into the mould in the ordinary way.
The juices resulting from this method of separating the beet juices are materially
purer than those resulting from the line treatment because the baryta deposits a
large number of non sugary materials of the beet juices which are not removed by
the lime treatment. The juices from the baryta separation may even be treated
immediately after saturation with carbonic acid and the complete removal of the
baryta without first filtering them by means of animal charcoal.
In order to separate the beet juice and other vegetable juices which I for shortness
Bake hereinafter omit, by means of sugar baryta I put this latter in excess quantity
directly into the juice and boil. The baryta slime of separation thereby produced
may during or after its production at once be treated with carbonic acid in order to
reinove the larger part of the excess of the baryta and to take away the golatinous
consistency from the slime by the admixture of carbonate of baryta. During this
separation with simultaneous saturation the carbonic acid may to a limited amount
be introduced, in order that the juice may retain a strong baryt alkality which is
only done away with after the slime has been removed by means of a second or
secondary saturation.
It is advantageous first to mix the sugar baryta required for the separation of a
given quantity of beet juice with a small quantity of such juice stirring it into a
milky consistency or "milk" and while stirring to pour it into the heated main
bulk of the beet juice During the subsequent boiling I then let in the carbonic
acid until the separation is completed.
The baryta slime of separation including the slime of saturation contains
coagulated albuminous substances and also all the inorganic and organic non sugary
materials deposited from the beet juice, also carbonate of baryta. When this
latter has been removed or washed out of the juice by the filter press or otherwise
it must be subjected to a special treatment for recovery of the baryta contained
therein. This consists in forming the slime at once or after drying and with or
without admixtures such as sawdust, smalls of coal, tar, or the like, into bricks or
pieces which are dried and made glowing hot in a furnace. Or the dried slime
may first be dry distilled in retorts for the purpose of obtaining the ammoniac, tar
and combustible gases for heating and lighting purposes and the residue remaining
in the retorts are then first together with the aforesaid admixture made into
bricks.
In the glowing of the slime the organic acids the albumen the pectine and the
like as well as the admixtures (if any) are first burnt and the carbonate of baryta
produced will by the further glowing be converted into caustic baryta.
The always small quantity of sulphate of baryta is transformed into sulphide

page_text: of barium while the other inorganic slime parts such as phosphoric acid iron and
manganese remain unchanged.
The slaking and manipulation of the caustic burnt baryta bricks is done according
to the known methods whereby is obtained firstly crystalized oxide of barium
Ba (OH), +8 H, O and secondly an undissolved romainder consisting mainly of
unchanged carbonate of baryta and also containing the aforesaid parts (phosphoric
baryta iron manganese and the like).
The crystals of baryta Ba (O H), + 8 H. O serve again to separate the sugar
from the uolasses according to Dubrunfaut's process, the saccharate of baryta
obtained thereby is then as stated again applied to the separation of the beet juice
and so on.
The aforesaid remainders from the slaking of the caustic burnt slime of separation
are collected and periodically once more made into bricks in the manner described,
made glowing hot and so on whereby a further amount of crystals of baryta aro
obtained. The remainder from this second brick manufacture may if required be
treated in like manner or else thrown away.
In the above described mode of preparation of the beet juices the whole amount
of sugar contained therein is obtained in crystallized form; the juices are dissolved
into sugar and into non-sugared substances. The sugar obtained possesses the pure
taste of the cane sugar Molasses are in this process only formed in a transitory
way as an intermediate product of which the sugar in the cycle of operations at
once again returns. In this process consequently the manufacture of sugar from
beet or plant juices is without production of sugar. A per centage of baryra which
might remain in the product obtained can be avoided by the same methods as
are used for the process of "Dubrunfaut" which have been found to answer in
The advantages of the mode of manufacture above described.
"
a Complete gain of all the sugar of the bect in the form of masse cuite"
possessing a very high degree of purity.
6 Excellent taste of the sugar obtained.
c Doing away with the costly filtration of the separated sugary juices over
animal charcoal, or an essential diminution of this stage of manufacture.
d Gain of ammonia tar combustible gases and other materials by the dry
distillation of the baryta slime of separation.
e Gain of all the nonsugary materials in the beet and useful employment of the
same as manure.
Having now described the nature of my said Invention and in what manner the
same is to be performed, I declare that I claim :-
First The separation or purification of the juices of beet and other sugar
containing plants by means of sugar baryta
Second The conversion of the baryta contained in the obtained slime of
separation and saturation into caustic baryta by forming this slime with or without
the addition of reducing and binding agents into compact masses or bricks which
are dried and made glowing hot
Third: The dry distillation of the baryta containing slimes of separation and
saturation before their conversion into caustic baryta as herein before secondly
claimed for the purpose of obtaining ammonia, tar, combustible gases, and other
products.
In witness whereof I the said Carl Scheibler have hereunto set my hand
and seal this Ninth day of August in the year of our Lord One thousand
eight hundred and eighty two.
