IMPROVEMENTS IN THE PROCESS OF REFINING SUGAR
Year: 1880

page_text: LETTERS PATENT to Albert Sauvée, Civil Engineer, of 22, Parliament. Street,
Westminster, in the County of Middlesex, for an Invention of " IMPROVEMENTS
IN THE PROCESS OF REFINING SUGAR," A communication from abroad by
Emile Commerson, of Marseilles, in the Republic of France.
PROVISIONAL SPECIFICATION left by the said Albert Sauvée at the Office
of the Commissioners of Patents on the 19th August 1880.
ALBERT SAUVÉE, Civil Engineer, of 22, Parliament Street, Westminster, in the
County of Middlesex. "IMPROVEMENTS IN THE PROCESS OF REFINING SUGAR."
A communication from abroad by Emile Commerson, of Marseilles, in the Republic
of France.
Up to the present time it has not been possible to convert all the syrup from
the first boiling into sugar fit for sale by one operation, that is to say, into
products similar to bastard and moist sugar (vergoise). The object in the mode of
working the boiled syrup has always been to obtain a certain proportion of raw or
moist sugars by extracting the molasses, such extraction being performed either by
running it off, by suction, or by the more common system of centrifugal action.
The improvement consists in the total conversion of the syrup into sugar ready
for sale.
The following is a general view of the operation: In the case where loaf sugar
is manufactured instead of treating the residuums from each boiling one after
the other, by which means sugars poorer and poorer in quality are obtained, all the
necessary operations for purifying and obtaining a better colour (whether patented
or otherwise) are performed at the same time on the green syrup (2nd jet), so as to
obtain after the operation a mass much purer in colour and much nicer to the
taste than that usually obtained. The mass is then disintegrated, and after being
dried to the required point is reduced to powder, similar to bastard, by treating it in
any suitable apparatus adapted for that purpose.
If the refinery produces only moist sugars, the first syrup resulting from the
melting of the colonial sugar is clarified, purified, and sufficiently filtered, and then
worked as above described.
The process can also be applied to purifying cane juice sugar (vesou). In this
case the improvement which is the subject of this application for a Patent has
nothing to do with Fryer's concretor, which produces an impure mass, compact but
not homogeneous, and which is not ready for general consumption.
The improvement can be applied either by itself or conjointly with the usual
centrifugal process, so as to allow mixings of various richness and quality.

In the case where loaf sugar is manufactured instead of treating the residuums
from each boiling one after the other, by which means sugars poorer and poorer in
quality are obtained, all the necessary operations for purifying and obtaining a
better colour (whether patented or otherwise) are performed at the same time on
the green syrup (2nd jet), so as to obtain after the operation a mass much purer in
colour and much nicer to the taste than that usually obtained. The mass is then
disintegrated; the apparatus for this purpose must be so constructed that this is
attained without the parts being allowed to clog together, and after being dried
to the required point on a series of drying boards for about forty-eight hours, until
the quantity of moisture does not exceed from 2% to 3% of the weight, it is
reduced to powder, similar to bastard, by treating it in a strongly built grinder.
If the refinery produces only moist sugars, the first syrup resulting from the
melting of the colonial sugar is clarified, purified,. and sufficiently filtered, and then
worked as above described.

The improvement can be applied either by itself or conjointly with the usual

Having now described the nature of my said Invention and the manner in which
it is to be performed, I declare that I claim,-
The immediate conversion of the whole of the green syrup or of the vesou into
powdered sugars ready for the market.
In witness whereof, I, the said Albert Sauvée, have hereunto set my hand
