AN IMPROVEMENT FOR THE PRESERVATION OF YEAST FOB MANURING PURPOSES
Year: 1869

page_text: LETTERS PATENT to Jean Baptiste Bernier, of 29, Wilmington Square,
Clerkenwell, in the County of Middlesex, Yeast Merchant, for the
Invention of "AN IMPROVEMENT FOR THE PRESERVATION OF YEAST FOB
MANURING PURPOSES."
Sealed the 10th September 1869, and dated the 11th March 1869.
PROVISIONAL SPECIFICATION left by the said Jean Baptiste Bernier
at the Office of the Commissioners of Patents, with his Petition,
on the 11th March 1869.
I, JEAN BAPTISTE BERNIER, of 29, Wilmington Square, Clerkenwell,
in the County of Middlesex, Yeast Merchant, do hereby declare the
nature of the said Invention for "AN IMPROVEMENT FOR THE PRESERVATION
OF YEAST FOR MANURING PURPOSES," to be as follows:-
The production of the yeast derived from the manufacture of beer is
generally in excess of its consumption, then it results that the yeast that
has not been used for the manufacturing purposes to which is is des-
tined, such as distilling of molasses and grain, is rapidly putrified and
becomes useless, and even a nuisance. There exists, however, in the
yeast certain properties that render it eminently qualified to make a
valuable manure, but it is first indispensable to preserve it from putre-

page_text: faction, and this is the object of my present Invention. To obtain this
end I contrive to rid the yeast of every moisture. To this effect I dry
it by the usual means, such as a proper heat, but I obtain this
desiccation by a peculiar process, which has especially the advantage of
giving at once a marketable product which can be used for agricultural
purposes. This process consists in mixing yeast with a suitable pro-
portion of quicklime, to which some plaster may be added. This mixture
produces a good manure. The proportion varies according to the
condition of the yeast, but generally 30 pounds of quicklime and
10 pounds of plaster, if the plaster is used to every hundredweight of
yeast, is best.
What I claim as my Invention is, the desiccation of yeast to preserve
it and use it for agricultural purposes.
SPECIFICATION in pursuance of the conditions of the' Letters Patent,
filed by the said Jean Baptiste Bernier in the Great Seal Patent
Office on the 11th September 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JEAN

for "AN IMPROVEMENT FOR THE PRESERVATION OF YEAST FOR MANURING PURPOSE,"
upon the condition (amongst others) that I, the said Jean Baptiste

NOW KNOW YE, that I, the said Jean Baptiste Bernier, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement thereof, that is to say :-
The production of the yeast derived from the manufacture of beer is
generally in excess of its consumption, then it results that the yeast that
has not been used for the manufacturing purposes to which it is des-
tined, such as distilling of molasses and grain, is rapidly putrified, and
becomes useless, and even a nuisance. There exists, however, in the
yeast certain properties that render it eminently qualified to make a
valuable manure, but it is first indispensable to preserve it from putri-
faction, and this is the object of my present Invention. To obtain this
end I contrive to rid the yeast of every moisture. To this effect I dry
it by the usual means, such as a proper heat, but I obtain this
desiccation by a peculiar process, which has especially the advantage of
giving at once a marketable product which can be used for agricultural
purposes. This process consists in mixing yeast with a suitable propor-
tion of quicklime, to which some plaster may be added. This mixture
produces a good manure. The proportion varies according to the con-
dition of the yeast, but generally 30 pounds of quicklime and 10 pounds
of plaster, if the plaster is used to every hundredweight of yeast, is best.
What I claim as my Invention is, the desiccation of yeast to preserve
it and use it for agricultural purposes.
In witness whereof, I, the said Jean Baptiste Bernier, havo
hereunto set my hand and seal, this Eighth day of September,
in the year of our Lord One thousand eight hundred and sixty-
nine.
