Liquors, Distillers' Wash and Vinegar Brewers' Wash,
Applicable also to other Processes.
We, FRANK FAULKNER of Crosswells Brewery, Oldbury, in the County of
Worcester, Consulting 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 appliance for use in circulating malt and raw grain worts when
producing ordinary malt liquors, distillers wash and vinegar brewers wash and in
other like or analogous processes to which this invention relates, has three modifi-
cations for adaptation to as many purposes in the said process. Under one form,
namely that in which it is adapted for use in circulating wort in the mash-tun and
aerating the same with hot air, the appliance consists of a case of cast iron or other
suitable metal, preferably cylindrical in shape through the middle of which is
passed a tube by which the wort is conducted as hereinafter described. At the
ends of the case aforesaid the tube passes through suitable stuffing boxes.
Embracing the tube, centrally disposed, as aforesaid, in the case, is an air pipe.
coiled round the said central tube and passing out at each end of the cylindrical
case through suitable stuffing boxes. The air pipe is preferably made of seamless
copper. The appliance is situated at or near the mash-tun, with which the central
pipe communicates above and below the appliance. To the interior of the
cylindrical case steam is admitted, and circulates around the coiled air pipe which,
as aforesaid, embraces the central tube. At one end the air pipe communicates>
with an air pump; at the other end it communicates with the wort tube at a point
above the steam chamber. By means of the pump aforesaid, or a separate pump,,
the wort drained from the mash-tun is forced upwards in the wort tube through
the steam chamber and, on its way thence to the sparge dish, the current or
blast of hot air in the air pipe heated in its passage through the coil in the said
chamber is injected into it. The wort is thus made to circulate and is aerated with
hot air.

page_text: As adapted for use only in aërating wort in the copper, underback or cooler or
other kindred vessel with hot air the central tube for the wort is dispensed with,
otherwise the appliance remains the same. The air, which is heated in its passage
through the coiled pipe, may be conveniently obtained from the pump which is
employed in the circulation and hot aeration of the mash tun wort.
As adapted for use in aërating wort with cold air in the fermenting vessels the
appliance remains the same in form as when used for hot aëration of wort in the
copper, under-back or cooler, but cold water or other cooling medium is made to
circulate about the coiled pipe in the cylindrical chamber for the purpose of
cooling the air passing through the said pipe. The air pipe or the coiled part
thereof is preferably. made of tin to obviate corrosion and fouling.
In
Referring to the accompanying sheet of illustrative drawings. Fig. 1 thereon
represents in section that form of the appliance under which it is, adapted for use
in circulating wort in the mash tun and for aërating the same with hot air.
the case A, preferably of cylindrical shape, as shown, is the copper tube B which
communicates at the lower end with the bottom of the mash tun and at the upper
end with the sparge dish By a pump or equivalent contrivance placed between
the mash tun and the lower end of the appliance the wort taken off at the bottom
of the mash tun is forced upwards in the tube B. Coiled around the tube B is an
air pipe C, preferably of seamless copper, in which an upward current of air from
the same pump which raises the wort, or from a separate pump, is maintained.
To the interior of the chamber A is admitted steam.or other heating agent. AB
the air traverses the coiled pipe C it is heated by the steam by which the said
pipe is enveloped, and is ultimately discharged while hot into the wort tube B,
and in addition to aerating the wort it assists in promoting the circulation thereof.
At Fig. 2 is represented in section a form of the improved appliance in which it
is adapted for heating air and in which it may be conveniently used in aerating
wort in the "under back," copper or cooler or other kindred vessel used in the
processes referred to or in processes allied thereto. The air pipe C is placed in the
heating chamber A and a current of air is forced through it by means of the same
pump, which is employed in the circulation and hot 'aération of the mash-tun wort,
or by a separate pump.
In adapting the appliance to the aeration with cold air of the wort when in the
fermenting vessels, the form of construction remains the same as in Fig. 2 but cold
water or other cooling agent is admitted to the chamber A instead of a heating
agent as above described. The air, pipe is, in this application of the apparatus,
preferably made of tin to obviate fouling and corrosion. The air may be conveniently
obtained from the same pumps or forcing appliance by which either or both of the
herein before described modifications of the appliance is or are supplied, and hence
a system of main air pipes communicating with one pump or forcing appliance.
may be adopted in a brewery from which the different appliances may be con-
veniently supplied.
Having now particularly described and ascertained the nature of this invention,
and in what manner the same is to be performed, we declare that we claim is:-
'
1st. The improved appliance for use in circulating and aërating with hot malt
and raw grain worts when producing ordinary malt liquors, distillers wash vinegar
brewer's wash and in other like or analogous processes, the said appliance consisting
of a chamber or vessel such as A. for receiving steam or other heating agent, and
enclosing the wort tube and air pipe coiled around the wort tube into which latter.
the air pipe ultimately discharges, the wort and air being first forced through the
heating chamber by a suitable pump or pumps or the equivalent thereof, sub-
stantially as herein before described with reference to Fig. 1 of the accompanying
sheet of drawings.
2nd. The modification for use in heating air for the hot aeration of under back,
copper, or cooler wert, or kindred vessel consisting of a coiled air pipe such as O
enclosed in a chamber such as A into which steam or other heating agent is received,
E

page_text: the air being forced through the coiled pipe by a pump or equivalent device,
substantially as herein before described with reference to Fig. 2 of the accompanying
sheet of drawings.
3rd. The modification referred to in the preceding claim as applied to the cold
aëration of wort in the fermenting vessels the coiled air pipe being immersed in
cold water or other cooling agent admitted to the chamber A substantially as
herein before described.
4th. The combination in the process of brewing malt liquors, distilling, vinegar
brewing and other kindred processes of the improved appliance for use in the
circulation and hot aëration of mash tun wort as herein before set forth with the
modification also hereinbefore set forth for the hot aëration of under-back copper
or cooler wort; and as applied to the cold aĕration of wort in the fermenting
vessels.
