PROVISIONAL SPECIFICATION.
Improved Process of and Apparatus for Chilling Beer Preparatory to
Bottling.
We, LAWRENCE BRIANT, of 24, Holborn Viaduct, London, Analytical Chemist,
and WILLIAM ADLAM, of 1, Ellbroad Street, Bristol, Engineer, do hereby declare
the nature of this invention to be as follows;-
This invention relates to chilling beer preparatory to bottling. One of its
objects is, by the special method of chilling adopted, to effect, in less time than
heretofore, precipitation of the contained albumenoids and other nitrogenous
constituents and the hop resins preparatory to filtration. Another object is to
dissolve, during such process, the carbonic acid which the beer already contains so
that the beer in high condition, that is to say, containing much carbonic acid gas,
is chilled, filtered and bottled without any material loss of that gas.
According to this invention, the casks in which the beer is contained are fitted
each with a metallic coil through which, when the beer is in fit condition for
bottling, is made to circulate brine cooled by means of an ice machine. In this
way the beer is chilled. While chilling is in progress, the beer is subjected to
pressure, either by charging carbonic acid gas into the cask or by continuous
pumping.
After having been kept under pressure in the cask for a period of time and at
a suitable temperature to effect the desired precipitation of the matters aforesaid
and the solution of its own gas contained in the beer, the beer is run out of the
cask into a closed filter such as is ordinarily employed for the purpose of filtering
beer after chilling.
From the filter the beer is conducted to the bottling machine.
From the time when the beer is run into the cask to the time when it is charged
into the bottles, it is kept from contact with external air, and from the time of
application of pressure to the beer the pressure is maintained throughout the
process. Accordingly, its own contained carbonic acid gas is preserved in the
beer in the dissolved state (carbonic acid gas being much more soluble in chilled
beer than at normal temperatures), brought about by the pressure exerted as afore-
said on the beer and by the low temperature.
Under this invention, the beer is brought into more direct contact with the
chilling agent and, accordingly, chilling is expedited.
During the chilling process, the employment of pressure may, if desired, be
dispensed with but, in that case, the absorption of the natural gas is not so com-
plete and, therefore, the ultimate result is less satisfactory.

page_text: the nature of this invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :-
This invention relates to chilling beer preparatory to bottling. One of its
objects is, by the special method of chilling adopted, to effect, in less time than
heretofore, precipitation of the contained albumenoids and other nitrogenous
constituents and the hop resins preparatory to filtration. Another object is to
dissolve, during such process, the carbonic acid which the beer already contains, so
that the beer in high condition, that is to say, containing much carbonic acid gas,
is chilled, filtered and bottled without any material loss of that gas.
According to this invention, the casks in which the beer is contained are fitted.
each with a metallic coil through which, when the beer is in fit condition for
bottling, is made to circulate brine cooled by means of an ice machine. In this
way the beer is chilled. While chilling is in progress, the beer is subjected' to
pressure either by connecting the cask with a cylinder of compressed carbonic
acid gas, or by continuous pumping.
After having been kept under pressure in the cask for a sufficient period of time
and at a suitable temperature to effect the desired precipitation of the matters
aforesaid and the solution of its own gas contained in the beer, the beer is run
out of the cask into a closed filter such as is ordinarily employed for the purpose
of filtering beer after chilling.
From the filter the beer is conducted to the bottling machine.
From the time when the beer is run into the cask to the time when it, is charged
into the bottles, it is kept from contact with external air, and from the time of
application of pressure to the beer the pressure is maintained throughout the
process. Accordingly, its own contained carbonic acid gas preserved in the
beer in the dissolved state (carbonic acid gas being much more soluble in chilled
beer than at normal temperatures), brought about by the pressure exerted as afore-
said on the beer and by the low temperature.
Under this invention, the beer is brought into more direct contact with the
chilling agent and, accordingly, chilling is expedited.
During the chilling process, the employment of pressure may, if desired, be
dispensed with but, in that case, the absorption of the natural gas is not so com-
plete and, therefore, the ultimate result is less satisfactory.
Having now particularly described and ascertained the nature of this
invention, and in what manner the same is to be performed, we declare that
what we claim is:-
A process of and apparatus for chilling beer preparatory to bottling, according
to which process chilling is effected by causing brine, cooled by means of an ice
machine, (or by causing other suitable cooling or refrigerating agent) to circulate
in a tubular coil immersed in the beer while the beer is contained in cask and is
preferably, but not necessarily, being subjected to pressure either by charging
carbonic acid gas into the cask or by continuous pumping, substantially as
hereinabove described.
