PROVISIONAL SPECIFICATION.
An Improved Process for the Preservation of Butter.
I, LÉON LUCIEN CARPENTIER, of 108, Rue Dareau, Paris in the Republic of
France, Manufacturer of Receptacles for Preserves, do hereby declare the nature
of this invention to be as follows:-
This invention relates to an improved process for preserving butter in the
fresh condition.
My improved process for preserving butter in the fresh condition is carried
out as follows:-The fresh butter is first worked in fresh water, in order to
extract all the portions of whey that it may contain and this worked butter is
placed in an apparatus for producing a vacuum so as to extract all the air
contained even in the body of the butter. For this purpose, the action of the
vacuum is prolonged for a suitable time. During this operation the butter can
be stirred by agitators fixed on a shaft extending into the interior of the bell
or vacuum chamber so as to effect the complete extraction of the air in the interior
of the butter.
When it appears that the butter has remained in the vacuum chamber for a
sufficient length of time, there is introduced into the apparatus, by any suitable
means, preferably carbonic acid gas, or the oxide of carbon or of nitrogen, in
such a manner as to sterilize, that is to say, to destroy any injurious germs which
may still be contained in the interior of the butter.
The fresh butter thus treated is afterwards withdrawn from the apparatus and
placed in cases or boxes which are filled up to about a centimetre and a half
from the top, afterwards the filling of the boxes is completed either with distilled
water or with cold water which has preferably been boiled.
The boxes are then closed by covers which are soldered or bezelled (spun) in
position.
Each cover is provided with a small tube of tin, in which there is placed a
hollow needle connected to an engine or pump by means of which a vacuum is
produced in the interior of the box which encloses the treated butter.
The conduit on which the said needle is mounted, is provided with a three-
way cock which enables the receiver to be put into communication either with
the vacuum apparatus, or with a receptacle containing carbonic acid gas.
When a vacuum has been produced in the box, the cock is closed to the vacuum
apparatus and the carbonic acid gas at a low pressure allowed to enter into the
box, after which the tube of the cover is nipped at its lower part.
To make the tube perfectly tir-tight after it is closed, this tube is previously
provided, in its interior, with a coating of a composition, produced by mixing
the following ingredients in a heated condition :-

I, LÉON LUCIEN CARPENTIER, of 108, Rue Darcau, Paris in the Republic of
France, Manufacturer of Receptacles for Preserves, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement;-
-
This invention relates to an improved process for preserving butter in the
fresh condition.
My improved process for preserving butter in the fresh condition is carried
out as follows: The fresh butter is first worked in fresh water, in order to
extract all the portions of whey that it may contain and this worked butter is
placed in an apparatus for producing a vacuum so as to extract all the air
oven that contained in the body of the butter. For this purpose, the action. of the
vacuum is prolonged for a suitable time. During this operation the butter can
be stirred by agitators fixed on a shaft extending into the interior of the bell
or vacuum chamber so as to effect the complete extraction of the air in the interior
of the butter.
•
When it appears that the butter has remained in the vacuum chamber for a
sufficient length of time, there is introduced into the apparatus, by any suitable
means, preferably carbonic acid gas, or the oxide of carbon or of nitrogen, in
such a manner as to sterilize, that is to say, to destroy any injurious germs which
may still be contained in the interior of the butter.
The fresh butter thus treated is afterwards withdrawn from the apparatus and
placed in cases or boxes which are filled up to about a centimetre and a half
from the top, afterwards the filling of the boxes is completed either with distilled
water or with cold water which has preferably been boiled..
The boxes are then closed by covers which are soldered, bezelled or spun in
position.
To enable the invention to be readily understood, I have shown in the accom-
panying drawing, but by way of example only, an arrangement whereby my
process can be conveniently and advantageously carried into practice.
In this drawing:-
Figure 1 is a vertical section of an apparatus for mixing or working the butter
during the action of the vacuum and the introduction of the carbonic acid gas
into the butter when the vacuum has been produced.
Figure 2 illustrates the putting into boxes of the treated butter..
Figure 3 is a vertical section of a box filled with treated butter and closed by
hezelling the cover.
In these figures, like letters of reference indicate the same parts.
My apparatus is composed essentially of a receiver a closed by a cover 6 pro-
vided with two flanged apertures or pipe-connections, of which one c, connected
to a pump or any other apparatus suitable for the purpose, permits a vacuum to
be produced in the interior of the apparatus, and the other d, serves for the
introduction of the carbonic acid gas.

page_text: The receptacle a bears, on its lower part, a slightly conical conduite of small
diameter. In order to prevent the introduction of the butter into this conduit
during the treatment, the conduit e is provided with a cock f.
In the interior of the receiver a is arranged an agitator or stirrer g in any
suitable manner, which stirrer is operated by hand by means of cranks h or by a
pulley receiving motion from any suitable motor.
Pressure-gauges i, k, placed on the cover bindicate respectively the vacuum in
the interior of the apparatus and the degree of pressure of the carbonic acid
gas.
My process of preserving butter, in the fresh condition, is effected in the follow-
ing manner -
The fresh butter being introduced into the receiver a and the cock f being closed,
the stirrer g is set in motion and a vacuum is produced in the apparatus.
When the vacuum is considered sufficient, carbonic acid gas is introduced
into the moving mass of butter.
This double operation of the vacuum and of the introduction of carbonic acid
gas can be repeated several times until the air contained in the butter is completely
eliminated.
When the treatment of the butter has been effected as above mentioned, a box l
is placed beneath the conduit e and the cock f opened.
The pressure exerted by the introduction of the carbonic acid gas into the
apparatus causes the treated butter to pass into the conduit e to fall into the
box 7.
As soon as this box is filled, the surface of the butter is equalized by means
of a palette for example, the box is then closed by bezelling its cover m.
If desired, each cover can be provided with a small tube of tin, in which there
is placed a hollow needle connected to an engine or pump by means of which a
vacuum is produced in the interior of the box which encloses the treated butter.
The conduit on which the said needle is mounted, is provided with a three-
way cock which enables the receiver to be put into communication either with
the vacuum apparatus, or with a receptacle containing carbonic acid gas.
When a vacuum has been produced in the box, the cock is closed to the vacuum
apparatus and the carbonic acid gas at a low pressure allowed to enter the
box, after which the tube on the cover is nipped at its lowest part.
To make the tube perfectly tir-tight after it is closed, this tube is previously
provided, in its interior, with a coating of a composition, produced by mixing
the following ingredients in a heated condition:-
1. Beeswax, pure
2. Baked resin
3. Tallow
-
1 kilogram.
. 300 grams.
- 150 grams.
The introduction of carbonic acid gas, either after the treatment of the butter
in a vacuum, or after it is put in boxes, as well as the filling of the latter with
distilled water or cold boiled water can in some cases be dispensed with without
thereby departing from the nature of my said invention.
The butter thus treated can be kept indefinitely in a fresh condition.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
1. A process of preserving butter in a fresh condition, consisting, after mixing.
or working the fresh butter in cold water in order to extract the whey there-
from, in submitting this butter to the prolonged action of a vacuum to extract
the air contained in the interior thereof and then placing the butter, after such
treatment, in boxes which are exhausted and then hermetically closed, sub-
stantially as described.
2. A process of preserving butter in a_fresh_condition, consisting,_after_mixing_

from, in submitting this butter to the prolonged action of a vacuum to extract
the air contained in the interior thereof and then placing the butter, after, such
treatment, in boxes, substantially as described.
3. In a process of preserving butter in the fresh state such as is hereinbefore
described, the introduction of carbonic acid gas by preference, into the butter
under treatment in a vacuum in order to destroy the injurious germs, and the
introduction of carbonic acid gas and distilled or cold boiled water into the box
or receiver containing the treated product, substantially as hereinbefore described
and for the purpose specified.
