Improvements in Treating Brewers' Wort.
We, FRANK FAULKNER of Crosswell's Brewery, Oldbury, in the county of
Worcester, Brewer, and WILLIAM ADLAM of Ellbroad Street, in the city and county
of Bristol, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention consists in the introduction into what is termed the "goods"
contained in brewers' mash tuns, of a current or blast of heated air whereby the wort
therein is made to circulate and the oxidation of the more readily alterable nitrogenous
compounds or bodies promoted.
The wort is impelled in the circulating pipes of the mash tun by a current of hot
air forced by a pump or other suitable appliance into the said pipes, and after
passing into the sparge dish, the wort flows on to the surface of the "
the tun.
goods" in
The temperature to which the air so employed is raised is regulated so as to provide
for rapid oxidation of the deleterious nitrogenous compounds or bodies, without
injuriously affecting the active diastatic bodies of the inalt extract.

Improvements in Treating Brewers' Wort.
We, FRANK FAULKNER, of Crosswells Brewery, Oldbury, in the county of
Worcester, brewer, and WILLIAM ADLAM, of Ellbroad Street, in the city and county
of Bristol, engineer, do hereby declare 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:—
::
The improved method of treating brewers wort to which this invention relates
consists in introducing to the "goods contained in the mash in of a current or blast
of heated air.
In those cases where it is desired that the wort shall circulate in addition to being
acrated by the current of heated air, the wort is impelled in the circulating pipes
connected with the mash tun by the action of the current of air forced, by a pump
or other suitable appliance, into the said pipes. From the said pipes the circulating
wort is delivered to the sparge-dish whence it flows into and is diffused among the
goods."
11
In those cases where aeration only of the wort is desired, the air is delivered into
the mash tun at or towards the bottom thereof either through the underlet or drain
pipes or, which is preferable, through pipes connected directly at various points to the
bottom of the vessel and, in this case, distributing pipes for further diffusion of the
air are fitted inside the mash tun under the plates of the false bottom thereof and are
readily removable for cleaning.
The air employed in either of the foregoing circumstances is of a temperature
regulated so as to provide for rapid oxidation of the deleterious nitrogenous com-
pounds or bodies without injuriously affecting the active diastasic bodies of the malt
extract.
Referring to the accompanying drawing, the figure shown represents a vertical
section of a mash tun having fitted thereto a pumping or forcing appliance and
attendant pipes for circulating and aerating the wort.
The wort as it comes from the drain pipes a is impelled upwards by a current of
heated air induced by the injectors fitted in the pipes and communicating with a
receiver or reservoir of hot air by the pipes & each fitted with a cock or tape. By
the pipes the wort is conducted to the sparge dish whence it is delivered to the
"goods" contained in the tun by the perforated distributing pipes g.
Instead of the injectors shewn in the drawing, any equivalent appliance may be
employed to maintain a current of heated air and so to keep the wort in circulation.
Where aeration alone of the wort is desired the air is not forced into the pipes by
which the wort is conducted to the sparge dish but is delivered into the mash tun at
or towards the bottom thereof either through the underlet or drain pipes or, which is
preferable, through pipes connected at various points to the bottom of the vessel,
and, in this case, distributing pipes for further diffusion of the air are fitted inside

for cleaning.
The air employed in either of the foregoing cases is of a temperature regulated so
as to provide for rapid oxidation of the deleterious nitrogenous compounds or bodies
without injuriously affecting the active diastasic bodies of the mali extract.
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 :-
1. In the process of brewing ale, porter and other like liquors, the introduction, by
means of an injector, pump, or equivalent appliance, into the wort as it comes from
the mash tam and is on its way to the "sparging" apparatus, of a current or blast of
heated air whereby the circulation of the wort is assisted and the oxidation of the
more readily alterable deleterious nitrogenous compounds or bodies in the wort
promoted, the temperature of such current or blast of air being regulated to obtain
the desired object without injuriously affecting the active diastasic bodies of the malt,
extract.
2. Apparatus for promoting the circulation and aeration of mash tun wort con-
sisting of drain pipes such as a, forcing appliance such as b, or the equivalent thereof,
pipes such as e for conducting the wort to the sparging apparatus, constructed and
arranged substantially as herein before described and shewn in the accompanying
drawing.
3. In the process of brewing ale, porter and other like liquors the introduction at
or towards the bottom of a mash tun of a current or blast of heated air whereby the
oxidation of the more readily alterable deleterious nitrogenous bodies is promoted
without injuriously affecting the active diastasic bodies of the malt extract,
substantially as herein before described.
