PROVISIONAL SPECIFICATION.
Improvements in the Refining or Extraction of Sugar from Raw
Sugar Solution, 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:-
This invention relates to the refining or extraction of sugar from raw sugar juice
or molasses and is designed to effect the extraction of sugar from juice or molasses
by the action thereon of ozone.
For this purpose we provide a tower or scrubber (or a series of such) the interior
of which is filled or packed with a mass of non oxidizable material, as for instance
with broken brick, earthenware, china, or glass. Above this is arranged a suitable
spraying or distributing apparatus by which the sugar solution is thrown upon the
material in the scrubber." A reservoir or well is formed in the bottom of the
scrubber in which the solution collects, and suitable inlets are provided at the upper
part of the tower for the raw sugar solution juice or molasses (hereinafter referred
to as the sugar solution), and at the lower part of the tower. for the admission of
ozonized air produced according to an invention forming the subject of another
application for Letters Patent by us bearing even date herewith and being No. 5222
of the year 1891.
The sugar solution being admitted at the top of the scrubber passes through the
distributing apparatus and then over the material with which the scrubber is filled
or packed whereby a very large surface of the said solution is exposed as it trickles
down the scrubber.
·
The ozonized air is caused to enter at the lower part of the scrubber, ascends
therein and coming into close contact with the descending solution energetically
oxidises the impurities.
The solution collects on the bottom of the scrubber and should it be found that
the process has not been completed, the said solution is caused to again pass through
the same scrubber or is preferably led directly into a second scrubber and thence
into a third and so on until the action is complete.
The employment of more than one scrubber is desirable not only for facilitating
the action, but also for allowing repairs on one or the other scrubber without
interrupting the progress of work.
The solution having been submitted to the above treatment is passed through a
series of filters which retain all oxidised impurities and other solid matters; then
the solution may be worked up in the usual manner.
The spent ozonized air which escapes from the scrubbers may be used for bleaching
or other suitable purposes. If however it is desired to destroy the ozone remaining
in the spent ozonized air it may conveniently be led into a suitable furnace and
burnt up or heated sufficiently to effect the decomposition of the ozone.
Dated this 24th day of March 1891.

Improvements in the Refining or Extraction of Sugar from Raw
Sugar Solution, Juice, or, Molasses.
We, AUGUST SCHNELLER of No. 1ª Amsterdam 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 and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
This invention relates to the refining or extraction of sugar from raw sugar juice
or molasses and is designed to effect the extraction of sugar from raw sugar solution
juice or molasses by the action thereon of ozone.
For this purpose we provide a tower or scrubber (or a series of such) the interior
of which is filled or packed with a mass of non-oxidizable material, as for instance
with broken brick, earthenware, china or glass. Above this is arranged a suitable
spraying or distributing apparatus by which the solution containing the raw sugar
juice or molasses is thrown upon the material in the scrubber. A reservoir or cell
is formed in the bottom of the scrubber in which the solution collects, and suitable
inlets are provided at the upper part of the tower for the raw sugar solution juice
or molasses (hereinafter referred to as the sugar solution) and at the lower part of
the tower for the admission of ozonised air produced according to an invention
forming the subject of another application for Letters Patent by us bearing even
date herewith and being Number 5222 of the year 1891.
The sugar solution being admitted at the top of the scrubber passes through the
distributing apparatus and then over the material with which the scrubber is filled
or packed whereby a very large surface of the said solution is exposed as it trickles
down the scrubber.
The ozonised air is caused to enter at the lower part of the scrubber, ascends
therein, and coming into close contact with the descending solution energetically
oxidizes the impurities.
The solution collects on the bottom of the scrubber and should it be found that
the process has not been completed the said solution is caused to again pass through
the same scrubber or as we prefer is led directly into a second scrubber and thence
into a third and so on until the action is complete.
The employment of more than one scrubber is desirable not only for facilitating
the action, but also for allowing repairs on one or the other scrubber without
interrupting the progress of work.
The solution having been submitted to the above treatment is passed through a
series of filters of fibrous, granular or other suitable material which retain all
oxidised impurities and other solid matters; then the solution may be worked up
in the usual manner.
The spent ozonised air which escapes from the scrubbers may be used for bleaching
or other suitable purposes. If, however, it is desired to destroy the ozone remaining
in the spent ozonised air, it may conveniently be led into a suitable furnace and
burnt up, or heated sufficiently to effect the decomposition of the ozone.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. Treating a solution of raw sugar juice or molasses with ozonised air in a
scrubber or scrubbers substantially as described for the purpose indicated.
2. Treating a solution of raw sugar juice or molasses with ozonised air in a
scrubber or scrubbers through which the said solution is caused to pass in a

page_text: direction opposite to that of the ozonised air and afterwards filtering the solution
substantially as described for the purposes indicated.
