1, WILLIAM PHILLIPS THOMPSON F.C.S, M.I.ME, of The Agency for
Foreign Patent Solicitors, 6 Loid Street. Liverpool, and 6, Bank Street,
Manchester, both in the County of Lancaster, 118 New Street, Birmingham in
the County of Warwick and 31 High Holborn in the County of Middlesex, Civil
Engineer, do hereby declare the nature of this invention and in what manuel the
same is to be performed, to be particularly described and ascertatued in and by
the following statement :-
1
This invention has for its object to bung the steeped or softened barley into the
condition of germination and sprouting with the aid of a drum by means of damp
air (under pressure or suction) of a suitable temperature in order, after the
expiration of about 8 days, to allow of its being removed as finished green
malt" from the dium by means of one or moro manholes This greou malt then
passes into second drum of similar constinction but other corresponding pro-
portions and
is treated therein with dry, warm or even hot air, under the
action of pressure or suction until it is in the condition of finished to refied
malt.
Several forms of construction of such malt diums are shown in the accompanying
drawings, in which-
Figure 1 is a sectional elevation,
Figure 2 a ti ausverse section on the lime A B of Figure 1, and
Figure 3 an end elevation of a simple drum.
All the drums consist of a cylindrical casing of sheet iron or other suitable
material resting ou four rollers, and may be set in rotation by means of worm
gearing or by friction rollers. The single drum shown in Figures 1, 2 and 3 has
on each of its ends a semi-perforated or slotted end-plate, the holes in one end
beng diagonally opposite those in other end. The whole perforated face of
these end-plates is provided with hoods a a of suitable material, which are connected
with an air inlet nozzle and an air outlet nozzle respectively, through which
nozzles the air can, according to requirements, be allowed to low in o pass off'
by means of a regulating valve. On the rotation of the drum, the ement of
an will take an alternately diagonal course through the moist barley, and thus
effect an even noration of the saine and thereby convert it into so called " green
malt.
Figme 4 shows a longitudinal section, and
"
Figure 5 a transverse section on the line C D of Figure 4, of a drum divided
into two parts which is really only a combination of two single drums, which have
a common chamber in the middle, to which chamber the moist air 13 convoyed
from the air inlet nozzle through a central tube e. The duection of the current
of air is exactly the same in this case as in the simple dium. The division of the
drum by the air chamber d has the advantage of enabling an independent aeration
of the malt to be obtained in both divisions in consequence of the regulation of the
air outlot by means of two slides on throttle valves ff arranged on the ends
thus possible to produce malt in various stages (one day's difference in germination)
in one dinin, so that only four instead of eight diums need to be fitted up in order
to ticat daily a half drumful.
It is

page_text: The au ingements of the drums hereinbefore described only allow diuins of short
length to be used. because the malt requires a copious aeration and cooling off,
which cannot be attained in 1ng air passages
In order to render it possible to se long drums, the interior of the same is
divided into a suitable number of compartments, as may be required for the
necessal) nciation.
Figures 6, 7, 8, 9 and 10 show a drum divided into four compartments, partly
perforated end plates being employed, and with a similar mode of working the
current of air as in the diums beienbefore mentioned. This drum has, as may
be seen in Figure 6, two an inlet chambers g g in the middle, and an air exit
chamber h, aud on its ends also two air exit chambers. The means for supplying
air to the air inlet chambers gg and for discharging an from the air outlet
chambers consist of a central pipe which is divided by a longitudinal central
partition into two halves for supplying and carrying away the an, and is connected
with each of the respective chambers
The ends of this central tube are partially closed, and one of the open halves
18 in communication by means of the au mlet nozzle with the air supply, whilst
the opposite open half is placed in communication by the an outlet nozzle with
the arrangement for carrying away the an. Both nozzles I have a suitable valve
for regulating the inlet and outlet of the au.
In order then to give the air a certain axial direction through the malt, entirely
perforated end plates may be in all cases employed instead of the partially
perforated ones as is shown in Figures 11, 12, 13 and 14 The malt contained in
one drun does not entirely fill the whole space of the dium, but the surface of
the layer of malt assumes an inclined position, as shown in Figures 8, 10 and 12,
on the rotation of the drum, in consequence of the friction on the walls of the
drum, or by means of suitable resistances placed therem (for the better turning
ver of the malt) Where entirely perforated bottom plates are used it is also
necessary that the free space remaining above the layer of malt shall remain
covered over both in the air inlet chambers and also in the an outlet chambers
which may be effected by means of single or double shield, n. The air is thus
forced to take a direct axial course through the malt
k
The shields n are, as shown in Figures 11, 13 and 14, loose and movable on
the central pipe and are provided with a counter weight n. As at one rotation
of the drum, the malt lying duectly round the central pipe & (shown in Figura 8
by a dotted cncle) is not brought out of its position of equipoise, no turning of
the malt lying round the pipe & takes place In order to overcome this diawback
also, the cential pipe inay be placed eccentrically in the drum as shown in
Figure 10, so that on the rotation of the dium the central pipe describes a
circle round the central axis of the dium, and thus causes a displacement of the
Inalt.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, as communicated to
me by my foreign corespondent, I declare that what I claim is
1. In a single malt drum, 01 one divided into several compartments, the
arrangement of end plates approximately elotted or perforated up to the centre,
and placed with the slotted on perforated surfaces diagonally to one another,
so that on the rotation of the drum, a constant change of the air curient
takes place in a diagonal direction in the drum, substantially as described and
illustrated
2. In a malt dum divided into two or more compartments, such as described in
Claim 1, the emplo, ment of two air outlet nozzles on the ends, with the object of
rendeung possible an independent aeration of each section of the dim by
regulating these outlets by means of slules or throttle valves ff, substantially as
described and illustrated.
3. Iu malt drums divided into several compartments, such as described in

page_text: Claim 1, the use of a central pipe & divided by means of a central longitudinal
partition, one half of such tube operating the supply of air to the air chambers,
whilst the other half communicates with the air discharge chambers, substantially
as described and illustrated.
4. A malt drum, such as described in the above claims, having its end plates and
the end plates of its air chambers entirely perforated or slotted in order to
produce au axial air current through the malt, and having movable shields n
arranged in the air supply and air exit chambers, which shields cover the space of
the air inlet and air outlet not filled by the malt, substantially as described and
illustrated.
5. In a malt drum of the kind described in the above claims, the eccentric
arrangement of the air supply and air discharge pipe k, substantially as and for the
purpose set forth
