ALFRED. JULIUS BOULT of the firm of W..P. Thompson & Boult Agents for
Foreign Patent Solicitors, of 323 High Holborn in the county of Middlesex,
Engineer "IMPROVEMENTS IN THE MANUFACTURE OF SUGAR FROM CANE AND IN
APPARATUS THEREFOR [A communication to him from Charles Blaudin of
la Pointe à Pitre, Guadeloupe, one of the West Indies.]
"
This invention relates to improvements in the manufacture of sugar from cane
and in apparatus to be employed therein.
According to. this invention the albuminous matters contained in the sugar cane
are coagulated by steam hot air or hot water before the cane passes to the mill in
which the extraction of its juice takes place
In carrying this invention into practice, a trough or vessel is provided which
surrounds the endless chain which carries the cane to the mill above mentioned.
The said vessel is provided with injectors or nozzles, say four for instance, for the
introduction of steam, there is also a waste pipe to allow the condensed water to
flow off. Where the chain passes into and out of this receiver, hinged traps or
valves are provided so as to close the vessel and prevent loss of steam.
In operation the cane before arriving to the mill passes through the said vessel
and is therein exposed to the effect of the steam and heated so as to effect the
coagulation of the albuminous matters whereby subsequent fermentation is
checked

SPECIFICATION in pursuance of the conditions of the Letters Patent, and of
an Order of the Lord Chancellor, filed by the said Alfred Julius Boult in the
Great Seal Patent Office on the 20th October 1883.
ALFRED JULIUS BOULT of the firm of W. P. Thompson and Boult Agents for
Foreign Patent Solicitors of 323 High Holborn in the county of Middlesex
Engineer "IMPROVEMENTS IN THE MANUFACTURE OF SUGAR FROM CANE, AND IN
APPARATUS THEREFOR a communication to me from Charles Blandin of La Pointe
à Pitre, Guadeloupe one of the West Indies
"
In the accompanying drawings Figure 1 is a side view of the apparatus. Figure 2
is a cross section upon line L M of Fig 1.
This apparatus mounted on the chain carrying the Cane to the extracting mill,
consists
1) of a large trough of sheet metal (A) into which extends the upper part of the
chain which feeds the Canc forward in proportion to the motion imparted to it.
2) four injectors or nozzles, whereof two, B, B' are in the upper part of the trough,
and two C and C' on the sides.
3) on the lower side of this trough, there is a hole or pipe D which allows the
condensed steam to be drawn off.
4) At the inlet and at the outlet of the trough two hinged traps or valves E, E¹
serving to retain the injected steam within the trough.
OPERATION OF THE APPARATUS
When the Cane which is to be worked up is placed on the chain, and when this
is set in notion, the injecting of steam, hot water or hot air is started as soon as
the Cane begins to pass into the apparatus and it continues as long as the chain
works.
'
The steam, hot air or hot water so injected raises the Cane to a temperature more
than sufficiently high for coagulating the albuminous matters contained in the sugar
"Cane and causes the latter to arrive at the mill at a sufficiently high temperature
to prevent all fermentation after extraction
Having now described the nature of the said invention and the manner of
performing the same, as communicated to me by my foreign correspondent, I wish
it to be understood that what I claim is
First. The method substantially as described, of coagulating the juice before
extracting it from the Cane.
Second. The combination of the trough A, nozzles or injectors B. B¹ C. C₁ and
valves E. E¹ with the travelling chain or band which supplies the cane-mill with
the Canes, substantially as described and illustrated
In witness whereof I the said Alfred Julius Boult have hereunto set my hand
and seal this seventeenth day of October in the year of Our Lord, one thousand
eight hundred and eighty three..
