IMPROVEMENTS IN MAKING BREAD AND BISCUITS
Year: 1857

page_text: LETTERS PATENT to Julien Blanc, of No. 59, Rue St. Louis, Batignolles,
near Paris, for the Invention of "IMPROVEMENTS IN MAKING BREAD AND
BISCUITS." A communication from Pierro Hanns and Louis Girard.
Sealed the 7th August 1857, and dated the 18th February 1857.
PROVISIONAL SPECIFICATION left by the said Julien Blanc at the
Office of the Commissioners of Patents, with his Petition, on the
18th February 1857.
I, JULIEN BLANC, of 59, Rue St. Louis, Batignolles, near Paris, do hereby
declare the nature of the Invention for "IMPROVEMENTS IN MAKING BREAD
AND BISCUITS," to be as follows:-
Heretofore in the manufacture of bread and biscuits, when the gluten
obtained in the manufacture of starch has been mixed with the dough, great
difficulty has been found in obtaining a complete mixture of the dough and
gluten, and also when the liquor which has been expressed from the grain, and
from which the starch has been allowed to settle, has been used for mixing
with flour to form dough, the liquor has fermented and given to the bread
an acid taste, or when this liquor has not been thus used the nutritive matters
contained in it have been wasted. Now, according to this Invention the
liquor which has been expressed from the grain is allowed to settle for about

page_text: twelve hours, when the starch contained in it will have subsided to the bottom;
the liquor is then run off into another vessel and again allowed to settle,
when the liquor is again run off. The last sediment is placed in bags and
subjected to pressure in order to obtain it in a dry state, or it may be dried
in any other convenient manner. The dry sediment is then mixed with the
gluten, from which the liquor containing the starch was expressed, so as to
form a paste which can readily be mixed with dough, and made into bread
or biscuits in the ordinary manner.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Julien Blanc in the Great Seal Patent Office on the 1
15th August 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JULIEN
BLANC, of No. 59, Rue St. Louis, Batignolles, near Paris; send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighteenth day of February, in the year of our
Lord One thousand eight hundred and fifty-seven, in the twentieth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Julien Blanc, Her special licence that I, the said Julien Blanc,
.my executors, administrators, and assigns, or such others as I, the said Julien
Blanc, my 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 of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN MAKING
BREAD AND BISCUITS," (a communication from Pierre Hanus and Louis Girard;)
upon the condition (amongst others) that I, the said Julien Blanc, my
executors or administrators, by an instrument in writing under my, or
their, or one of their hands and seals, should particularly describe and ascer-
tain 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 I, the said Julien Blanc, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-

page_text: formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say :-
Heretofore in the manufacture of bread and biscuits, when the gluten
obtained in the manufacture of starch has been mixed with the dough, great
difficulty has been found in obtaining a complete mixture of the dough and
gluten, and also when the liquor which has been expressed from the grain,
and from which the starch has been allowed to settle, has been used for
mixing with flour to form dough, the liquor has fermented and given to the
bread an acid taste, or when this liquor has not been thus used the nutritive
matters contained in it have been wasted. Now, according to this Invention
the liquor which has been expressed from the grain is allowed to settle for
about 12 hours, when the starch contained in it will have subsided to the
bottom; the liquor is then run off into another vessel and again allowed to
settle, when the liquor is again run off. The last sediment is placed in bags
and subjected to pressure, in order to obtain it in a dry state, or it may be
dried in any other convenient manner. The dry sediment is then mixed with
the gluten, from which the liquor containing the starch was expressed, so
as to form a paste which can readily be mixed with dough, and made into
bread or biscuits in the ordinary manner.
Having thus stated the nature of the said Invention, I will proceed more
fully to describe the manner of performing the same:-
In order to obtain gluten, flour is first made into dough, as heretofore, and
the starch is to be washed out therefrom in like manner to that heretofore
practised, and in place of simply mixing the gluten thus obtained with dough
or with flour, as has heretofore been practised, the wash water containing
the starch is to be allowed to settle for about twelve hours, by which tho
starch will be deposited. The liquor is to be run off from such starch into
another vessel, where it is to be allowed again to settle, and the sediment
thus obtained is to be drained, then pressed free from fluid, and then dried
in any convenient manner. In place of subjecting the matters which settle
in the second vessel to pressure to separate the liquor therefrom, the fluid
may be separated by pouring or spreading such sediment whilst still in a
semi-fluid state on a moving filtering cloth, and the filtration will be quickened
by giving to the moving filtering cloth a shaking or quick tremulous motion.
The sediment will thus be more readily obtained separated from the fluid,
and such sediment is then to be dried in any convenient manner.
The dry
product thus obtained is to be mixed with the gluten, and the gluten thus
combined is then to be mixed with dough or with flour, and used in the

page_text: manufacture of paste or dough in the ordinary manner, which is to be used
in making of bread, biscuits, and other preparations for food.
In witness whereof, I, the said Julien Blanc, have hereunto set my hand
and seal, this Twelfth day of August, in the year of our Lord Ono
thousand eight hundred and fifty-seven.
