IMPROVEMENTS IN SUGAR BOILING
Year: 1864

page_text: LETTERS PATENT to Edward Beanes, of 24, Argyll Street, in the
County of Middlesex, Engineer, and Conrad William Finzel, of the
City of Bristol, Sugar Refiner, for the Invention of "IMPROVEMENTS IN
SUGAR BOILING."
Sealed the 20th October 1864, and dated the 5th May 1864.
PROVISIONAL SPECIFICATION left by the said Edward Beanes and
Conrad William Finzel at the Office of the Commissioners of Patents,
with their Petition, on the 5th May 1864.
We, EDWARD BEANES, of 24, Argyll Street, in the County of Middlesex,
Engineer, and CONRAD WILLIAM FINZEL, of the City of Bristol, Sugar
Refiner, do hereby declare the nature of the said Invention for "IMPROVE-
MENT IN SUGAR BOILING," to be as follows:-
Our Invention consists in the use of hot water, at or as near as may be
the boiling point, or of very low pressure steam for boiling sugar in vacuum
pans.
Hitherto, for such purposes, steam has been used at temperatures of 225°
Fahrenheit, and upwards, equal to a pressure of 4 lbs., and upwards, whereby
there has always been more or less carbonization, and consequently coloring
of the sugar, for it has hitherto been deemed necessary to use steam of such
high temperatures in such process, in order that sufficient heat may be
obtained throughout, and at the end of the worm or tubes used in such.
vacuum pans, to cause the proper evaporation of the syrup or liquor.

page_text: Now our improvement consists in using hot water at or as near as may
be the boiling point, or steam at a temperature:not exceeding 215° Fahren-
heit, or at a pressure never exceeding 1 lbs. to the square inch, for the purpose
of boiling the syrup or liquor without carbonization. To effect this object
instead of using the long tubular vacuum pan and tubes; or the ordinary
vacuum pan with worms, as at present in use, we dispense with the use
of the vacuum pan with worms, using a tubular vacuum pan, reducing the
length thereof, and of the tubes therein; and augmenting its diameter, increas-
ing at the same time the number of tubes therein in proportion to the
diameter of the pan, so that it will only be necessary for the heating thereof
to, use hot water or steam as aforesaid at a temperature below the carbonizing
point of saccharine syrups, while from the shortness of the tubes in the pan
the
water or steam will continue sufficiently hot during its passage through such
tubes so as to be perfectly effective for the purpose of boiling the saccharine
liquids and causing the proper evaporation. throughout the pan without
causing any carbonization and coloring of the sugar.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Edward Beanes and Conrad William Finzel in the Great
Seal Patent Office on the 4th November 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, EDWARD
BEANES, of 24, Argyll Street, in the County of Middlesex, Engineer, and
CONRAD WILLIAM FINZEL, of the City of Bristol, Sugar Refiner, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifth day of May, in the year of our Lord One
thousand eight hundred and sixty-four, in the twenty-seventh year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said Edward Beanes and Conrad William Finzel, Her special licence
that we, the said Edward Beanes and Conrad William. Finzel, our exe-
cutors, administrators, and assigns, or such others as we, the said Edward
Beanes and Conrad William Finzel, our executors, administrators, and
assigns, should at any time agree with, and no others; from time to time
and at all times thereafter during the term therein expressed, should and
lawfully might make, use, exercise, and vend, within the United Kingdom

page_text: of Great Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for "IMPROVEMENT IN SUGAR BOILING," upon the condition (amongst
others) that we, the said Edward Beanes and Conrad William Finzel, our
executors or administrators, by an instrument in writing under our, or their,
or one of their hands and seals, should particularly describe and ascertain
the nature of the said Invention, and in what manner the same was to
be performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date of
the said Letters Patent...
NOW KNOW YE, that we, the said Edward Beanes and Conrad William
Finzel, do hereby declare the nature of our said 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 use of hot water at or as near as may be
the boiling point, or of very low pressure steam for boiling sugar in vacuum
pans.
Hitherto, for such purposes, steam has been used at temperatures of
225 Fahrenheit, and upwards, equal to a pressure of 4, lbs. and upwards,
whereby there has always been more or less carbonization, and consequently
coloring of the sugar, for it has hitherto been deemed necessary to use
steam of such high temperatures in such process in order that sufficient
heat may be obtained throughout, and at the end of the worm or tubes
used in such vacuum pans to cause the proper evaporation of the syrup or
liquor.
Now our improvement consists in using hot water continuously kept at
or as near as may be the boiling point, or steam at a temperature not
exceeding 215 Fahrenheit, or at a pressure not exceeding 1lbs. to the square
inch, or as near to such temperature and pressure as it can be kept in
practice so as to boil the syrup or liquor without carbonization. To effect
this object instead of using the long tubular vacuum pan and tubes, or the
ordinary vacuum pan with worms as at present in use, we dispense with
the use of the vacuum pan with such worms, using a tubular vacuum pan, but
reducing the length of the tubes therein, increasing at the same time the
number of tubes according to the evaporating surface required, so that it
will only be necessary for the heating thereof to use hot water or steam as
aforesaid, at a temperature below the carbonizing point of saccharine syrups,
while from the shortness of the tubes in the pan, the water or steam will
continue sufficiently hot during its passage through such tubes, so as to

page_text: be perfectly effective for the purpose of boiling the saccharine liquids
and causing the proper evaporation throughout the pan without causing
any carbonization and colouring of the sugar.
In witness whereof, we, the said Edward Beanes and Conrad William
Finzel have hereunto set our hands and seals, this Fourth day of
November, in the year of our Lord One thousand eight hundred and
sixty-four.
