Improvements in Treating Brewers' Wort and Apparatus therefor.
We, WILLIAM ADLAM, of Wier and Ellbroad Street, in the city and county of
Bristol, engineer, and FRANK FAULKNER, of Crosswells Brewery, Oldbury, in the
county of Worcester, consulting brewer, do hereby declare the nature of this
invention to be as follows :-
This invention consists in treating brewers' wort, by means of specially designed
apparatus, in such manner that the general quality of the wort is thereby improved
and an increased proportion of dextrine results.
In practically working this invention the wort from the mash tun is conducted to
and made to circulate through a multitubular heating vessel in which, by means of
steam or other suitable heating agency, such wort is raised either to boiling point or
may, indeed, be actually boiled. From this vessel the wort is conducted to a cooling
vessel of substantially similar construction to the vessel first mentioned. In this
second vessel the temperature of the circulating wort is reduced again, either through
the agency of cold air or other suitable cooling agent, to the requisite degree of
temperature, the wort being then resparged on to the mash tun "goods."
By thus subjecting the circulating wort to distinct ebullition, again cooling to a
temperature suitable for sparging, and subsequently bringing such treated wort under
the influence of the active principles of malt extract still present in the mash tun
goods," the general quality is modified and improved in character, while the
proportion of dextrine is materially increased.
CE
The process may be described as decoction of wort as distinct from decoction of
mash.

Improvements in Treating Brewers' Wort and Apparatus therefor.
We, WILLIAM ADLAM, of Weir and Ellbroad Street, in the city and county of
Bristol, engineer, and FRANK FAULKNER, of Crosswells Brewery, Oldbury, in the
county of Worcester, consulting brewer, 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:-
This invention consists in treating brewers' wort in specially designed apparatus in
such manner that the general quality of the wort is improved and an increased
proportion of dextrine results.
According to this invention the wort from the mash tun is conducted to and made
to pass through the tubes of a multitubular vessel. Steam or other suitable heating
agent is admitted to the vessel and surrounds the tubes through which the wort is
flowing. The wort is thus heated to boiling point or may, indeed, be actually boiled.
From this vessel the wort is conducted to a cooling vessel of similar construction to
the vessel first mentioned.
In the second vessel the temperature of the wort is reduced and when cooled to the.
required degree (185° to 165° F.) the wort is re-sparged on to the "goods" in the
mash tun.
Referring to the accompanying drawing, Fig. 1 thereon represents a vertical
section of a multitubular vessel constructed and arranged for heating or cooling
brewers' wort in accordance with this invention. Fig. 2 is a transverse section on
the line, Fig. 1.
In the employment of the vessel for heating wort the wort is forced by the
passage a into the tubes and passes out therefrom by the passage a¹ at the top. In
its passage through the tubes 6 of the vessel the wort is heated by means of steam or
other heating agent which is admitted by the pipe d and surrounds the said tubes.
The wort is thus heated to boiling point or actually boiled. The heating agent passes
out at the top by the pipe e.
The wort is conducted from this vessel to a similar vessel and as it passes through
the tubes thereof its temperature is reduced by means of cold air or other cooling
agent which passes through the vessel in the same way as hereinbefore described with
reference to the passage of steam or other heating agent. When thus cooled to the
requisite degree the wort is re-sparged on to the goods" in the mash tun
By thus subjecting the circulating wort to distinct ebullition, again cooling to a
temperature suitable for sparging and subsequently bringing such wort under the
influence of the active principle of malt extract still present in the mash tun "goods,"
the general quality of the wort is modified and improved in character and the
proportion of dextrine resulting is materially increased.

page_text: 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. An improved process of treating mash tun wort by subjecting the same to
distinct ebullition, again cooling the same to a suitable temperature for resparging
and thereafter resparging the wort on the "goods" in the mash tun, substantially as
herein above described.
2. The use for heating brewers' wort, of a multitubular vessel through the tubes in
which the wort is made to pass and in which it is raised to the required temperature
by means of steam or other heating agent admitted to the said vessel and having
access to the exterior of the said tubes, substantially as herein above described.
3. The use for cooling brewers' wort, of a multitubular vessel through the tubes of
which the wort is made to pass and in which it is lowered to the required temperature
by means of cold air or other cooling agent admitted to the said vessel and having
access to the exterior of such tubes, substantially as herein above described.
