Improvements in the Treatment of Saccharine and Sacchariferous
Matters for the Purpose of Decolouring, Purifying, or Refining
them.
We ARTHUR BRIN of 59 Brompton Crescent in the County of Middlesex, Engineer
and Chemist, and LEON QUENTIN BRIN of 7 Rue Gavarni Paris in the Republic of
France Engineer and Chemist do hereby declare the nature of our said Invention to
be as follows:-
Our Invention consists in the following treatment of saccharine or sacchariferous
matters.
We introduce the matters to be treated, or a solution thereof, into a churn
or vessel in which they can be violently agitated. This churn or vessel is closed
air tightly and must be of wood or other material not injuriously acted upon
by the materials introduced thereinto. We may conduct the
process at
ordinary temperatures or we may heat the matters under treatment which may be
effected by means of a steam pipe or coil or by direct contact of steam or both to a
temperature of about 50° Centigrade. We introduce into the churn or vessel a solu-
tion of chlorine and lime or chloride of lime together with alumina or aluminous earth
and by the action of beaters or the like chlorine gas is developed and comes into
intimate contact with the matters under treatment so that they are decoloured and
disinfected.
The small quantity of chloric acid which is developed produces hydrochloric acid
and oxygen. The oxygen acts as a purifier and also as a decolourizer or bleacher.
And in order to prevent the acid from injuring the matters under treatment we add
an agent which will cause precipitation of impurities a suitable agent being carbonate
of soda or a solution thereof. The matters treated may then be filtered through
carbonate of lime. Filtration through animal charcoal is not neccessary.

We ARTHUR BRIN of 59 Brompton Crescent in the County of Middlesex Engineer
and Chemist and LEON QUENTIN BRIN of 7 Rue Gavarni Paris in the Republic of
France Engineer and Chemist 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 :-
Our Invention consists in the following treatment of Saccharine or Sacchariferous
matters.
We introduce the matters to be treated or a solution thereof into a churn or vessel
in which they can be violently agitated. The matters or solution thereof may be at
ordinary temperatures but we preferably employ a temperature of about 60° Centi-
grade. The churn or vessel is closed air tightly and must be of wood or other material
not injuriously acted upon by acid or by the gases generated. The heating of the
matters under treatment may be effected by means of a steam pipe or coil or by
direct contact of steam; or both plans may be adopted. We introduce into the churn or
vessel a solution of chlorine and lime or chloride of lime together with alumina (or
its equivalent in this connection such as Alum, Sulphate of Alumina, Fuller's earth or
China clay) and by agitation due to the action of beaters or the like chlorine gas is
developed and comes into intimate contact with the matters under treatment so that they
are decoloured and disinfected.
The oxygen liberated acts as a purifier and also as a decolorizer or bleacher. To
prevent injury to the matters under treatment by tendency to acidity we add an alkali
which on the score of efficiency and economy we prefer to be Carbonate of soda or a
solution thereof. The matters treated may then be filtered through Carbonate of
lime. Filtration through animal charcoal is not necessary. The proportions by weight
of the materials which we prefer are to every 1000 (one thousand) parts by weight of
the matters under treatment; pure Chloride of lime 25 (twenty five) parts by weight;
Alumina or the like 1 (one) part by weight and Carbonate of soda or other
alkali 5(five) parts by weight but we do not limit ourselves to any precise
proportions.
The Invention is applicable to the treatment of saccharine and sacchariferous
matters generally such for example as raw cane sugar or juices or the juices or syrups
obtained from beet-root for sugar making.
Having now particularly described and ascertained the nature of our said Inven-
tion and in what manner the same is to be performed we declare that what we
claim is.―
The treatment of saccharine or sacchariferous matters substantially as and for the
purposes hereinbefore described.
