PROVISIONAL SPECIFICATION,
Improvements in the Refining of Sugar Juice or Molasses.
We, AUGUST SCHNELLER of No. 1 Amsterdamer Veerkade, The Hague,
in the Kingdom of Holland, Chemist and Electrical Engineer, and WILLIAM
JOHN WISSE, of 25 Zwarteweg, The Hague, aforesaid, Engineer; do hereby
declare the nature of this invention to be as follows:-
Sugar, sugar juice and molasses whether ohtained from cane or from beetroot,
ordinarily contain in greater or lesser quantities certain mineral and organic bodies..
the removal of which by processes heretofore adopted involves much trouble and
expense, whilst their presence is highly injurious not only because it results that
there is a lower percentage of saccharine matter in the refined product but also in
sugar, whoreln
consequence of the liability to generation in the higher qualities of
whiteness is a desideratum, of coloring matter that greatly depreciates the
commercial value of such sugar.
Now this invention has for its object the removal of the injurious bodies in
question in an economical manner.
1.
'
For this purpose the sugar, sugar juice or molasses, as the ouse may be, is
subjected not only to the action of ozone but also to the action of carbonic acid
gas, whereby the injurious bodies referred to are precipitated and can be readily
removed by filtration.
:
This invention can be carried out in various ways.
When refining, according to the invention forming the subject of our application
for Letters Patent No. 5236 dated March 24th 1891, that is to say by subjecting
raw sugar.juice to the action of ozone or ozonised air in a scrubber or scrubbers,
the carbonic acid can be introduced into the scrubber or scrubbers pari pussu with
ozone or ozonized air so that all the refining processes including the precipitation
of the injurious bodies referred to will be carried on simultaneously. Or after the
raw sugar juice has been treated with ozone in the scrubber or scrubbers mentioned
in the Specification of our said former application for Letters Patent, it can be
caused to pass through another scrubber or other scrubbers wherein the said juice is
exposed to the action of carbonic acid gas which precipitates the injurious bodies
as described.
But sugar or sugar juice that has been refined by other processes than that
forming the subject matter of our before mentioned application for Letters Patent,
may be treated with ozone or ozonized air and carbonic acid gas according to the
present invention.

COMPLETE SPECIFICATION.
Improvements in the Refining of Sugar Juice or Molasses.
We, AUGUST SCHNELLER of No. 14 Amsterdamer Veerkade The Hague,
in the Kingdom of Holland, Chemist and Electrical Engineer, and WILLIAM
JOHN WISSE, late of 25 Zwarteweg, The Hague, aforesaid, now of Wittenkade 140
Amsterdam 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 :-
Sugar, sugar juice and molasses whether obtained from cane or from beetroot,
-ordinarily contain in greater or lesser quantities certain mineral and organic bodies
the removal of which by processes heretofore adopted involves much trouble and
expense whilst their presence is highly injurious not only because it results that
there is a lower percentage of saccharine matter in the refined product, but also in
consequence of the liability to generation in the higher qualities of sugar, wherein
whiteness is a desideratum, of coloring matter that greatly depreciates: the
commercial value of such sugar.

Now this invention has for its object the removal of the injurious bodies in
question in an economical manner.
For this purpose the sugar, sugar juice or molasses, as the case may be, is
subjected not only to the action of ozone but also to the action of carbonic acid
gas, whereby the injurious bodies referred to are precipitated and can be readily
removed by filtration.
This invention can be carried out in various ways.

When refining according to the invention forming the subject of Letters Potent
granted to us No. 5236 dated March 24th 1891, that is to say by subjecting
solution of raw sugar juice or molasses whilst descending through a scrubber or
scrubbers to the action of ozone or ozonised air, the carbonic acid can be introduced
into the bottom of the scrubber or scrubbers pari paesu with the ozone or ozonised
air so that all the refining processes including the precipitation of the injurious
bodies referred to will be carried on simultaneously. Or after the solution of raw
sugar juice or molasses lias been treated with ozone in the scrubber or scrubbers
mentioned in the Specification of our said former Letters Patent, it can be caused.
uto pass through another scrubber or other scrubbers wherein the said juice is,
exposed to the action of carbonic acid gas which precipitates the injurious bodies
as described. The sugar juice or molasses thus treated is then filtered and treated
in the ordinary manner.
But sugar or sugar juice or molasses that has been refined by other processes
than that forming the subject matter of our before mentioned application for
Letters Patent, may be treated as described with ozone or ozonised air and
carbonic acid gas according to the present invention.
1.
Having no
now particularly described and ascertained the nature of the Faid inven-
tion and in what manner the same is to be performed we declare that what 'we
-claim is :-
In the refining of sugar juice or molasses, subjecting the solution of sugar juice
or molasses to the simultaneous or successive action of ozone or ozonised air
and carbonic acid substantially in the manner lierein described for the purpose
specified.
