JOHN CAIRNS WILSON, of Newry Brewery, Newry, Ireland.
IN THE PROCESS OF BOILING WORTS AND OTHER LIQUORS AND IN APPARATUS
USED THEREIN."
"
My Invention has for its object the retention of the fine aroma of the hop or
other flavour which is ordinarily allowed to escape in the process of boiling worts
and other liquors, and consists in the adaptation and application to the copper of a
condenser or condensing apparatus for the purpose of condensing the steam as
quickly as it is generated in the copper, and thereby preventing the steam from
escaping as usual.
.
A condenser is to be applied either inside the copper or in a pipe leading from
the copper. The condenser and pipe leading from the copper can be so constructed
and arranged as to allow the whole of the condensed steam to fall back into the
copper, or to flow into a separate receiver, in order to be afterwards added to the
product in any desired quantity. The condensing may also be effected in a receiver
as well as in the copper and pipe leading from the copper. The steam may also
be condensed in an open copper.
The condenser may consist of a series of tubes, through which cold water is
caused to flow, or it may be any suitable form of cooling or refrigerating apparatus.
By condensing the steam as fast as it is generated in the copper, and thereby
preventing its leaving the copper at all, the whole of the flavour and essential
oil of the hops (or the flavour of other liquor) will be retained, thereby materially
adding to the keeping quality of the article, while at the same time heating the
water for further operations and effecting a saving of fuel, also causing a vacuum
in the copper and increasing the intensity of the boiling, and also effecting a saving
of hops.

JOHN CAIRNS WILSON, of Newry Brewery, Newry, Ireland. "IMPROVEMENTS
IN THE PROCESS OF BOILING WORTS AND OTHER LIQUORS AND IN APPARATUS
USED THEREIN."
My Invention of "Improvements in the Process of Boiling Worts and other
Liquors and in Apparatus used therein," has for its object the retention of the fine
aroma of the hop or other flavour which is ordinarily allowed to escape in the
process of boiling worts or other liquors, and consists in the adaptation and
application to the copper, whether it be close or open; of a condenser or condensing
apparatus for the purpose of condensing the steam as quickly as it is generated in
the copper, and thereby preventing the steam from escaping as usual.
A condenser is to be applied either inside the copper or in connection with a
pipe leading from the copper. The condenser and pipe leading from the copper
can be so constructed and arranged as to allow the whole of the condensed steam
to fall back or return into the copper, or to flow into a separate receiver, in order
to be afterwards added to the product in any desired quantity. The condenser
may consist of a series of tubes, through which cold water is caused to flow, or it
may be any suitable form of cooling or refrigerating apparatus.
By condensing the steam as fast as it is generated in the copper, and thereby
preventing its leaving the copper at all, the whole of the flavor and essential oil
of the hops (or the flavour of other liquor) will be retained, thereby materially
adding to the keeping quality of the article, while at the same time heating the
water for further operations and effecting a saving of fuel, also causing a vacuum in
the copper and increasing the intensity of the boiling.
Having thus stated the nature of the said Invention, I will proceed to describe
more particularly in what manner the same is to be performed by the aid of the
accompanying Drawing, in which is represented an arrangement of the apparatus
as adapted for use in connection with two or more coppers.
DESCRIPTION OF THE DRAWING.
.A, A, are two coppers, in which the process of boiling worts or liquors is carried
on; B, B, are pipes, through which steam as it is generated in the coppers can
pass into the main pipe C leading into the condenser D, which may be of the form
shown, or of other suitable form. The condenser as shown is composed of a vessel
containing a set of tubes E, E, through or around which cold water can be supplied
in order to produce the condensation required. F is a pipe for admitting cold
water to the tubes E, E, for surface condensing; G is a pipe for the exit of hot
water;
H is a pipe for direct condensing; I is a pipe through which the condensing
vapour returns from the condenser D to the coppers A, A, or to a separate receiver
not shewn in the Drawing. The several cocks or taps for regulating the communi-
cation between the coppers and the condenser are represented at K, K. The
escape for steam is at L, and M is a small pipe to show whether the condensed
vapour is returning to the copper through the proper pipe.
It will be readily understood on reference to the Drawing that as steam is
generated in the coppers A, A, it will pass therefrom through the pipes B, B, into
the pipe C and thence into the condenser D, from which it will return in the
form of condensed vapour through the pipe I to the coppers A, A, or to a separate
receiver.

page_text: The condenser may be adapted and applied to the copper otherwise than as
represented in the Drawing, as, for instance, it might be placed in the steam pipe
leading from the copper, but the arrangement so represented is preferable where
several coppers are in use, as one apparatus is thereby rendered capable of working
all the coppers.
Having thus described the nature of the said Invention, and in what manner
the same is to be performed, I hereby declare that what I claim as of my Invention
is, the adaptation and application of a condenser or condensing apparatus to a
copper or coppers, as and for the purpose hereinbefore described.
In witness whereof, I, the said John Cairns Wilson, have hereunto set my
hand and seal, the Eighth day of November, in the year of our Lord One
thousand eight hundred and eighty.
