Improvements in Apparatus for Malting Grain.
I, FREDERICK WILLIAM GOLBY, of 36 Chancery Lane, in the County of
Middlesex, Patent Agent, do hereby declare the nature of this invention, as
communicated to me by Johann Jungbluth, of Friesenwall 86, Cologne, Germany,
to be as follows:-
In the germinating process of malting the grains take up oxygen, it is therefore
necessary, in addition to the presence of sufficient moisture and air, to supply the
germinating grains with a sufficient quantity of oxygen to enable the process of
germination to be properly carried out. As it is scarcely possible by steeping
and soaking to furnish the grains with the entire quantity of moisture which is
necessary to a complete and regular germination, it is necessary in the first place
to construct a malting apparatus by which the requisite air and moisture can be
supplied in a regular manner to the grain during the germination thereof. The
success of this operation is dependant principally on the condition of the malting
apparatus which must be as far as possible independant of outside influences..
The object of the present invention is the construction on the above mentioned
principles of malting apparatus in such a manner that the malt stuff heaped up in
regular quantities on a comparatively small floor surface can by means of electricity
be quickly brought to germination, and the temperature and also the degree of
moisture of the malt stuff under treatment reliably adapted to the conditions
favourable at the time to the germination.
To carry out the principles above indicated it is necessary to so construct the
apparatus as to produce in the inside of the same a cool moist air which produces
an equal temperature on the soaked grain thereby preventing it from changing
colour and allowing all the grains to germinate equally.
The apparatus is built up of two separate floor beds one above the other.
The germ floor consists of quadrilateral plates of tin coated sheet iron or similar
metal, which are furnished with fine narrow pierced openings. These plates are
fastened to a grid formed of frames which lie free on the under floor so that
between the said under floor and the germ floor is formed a free space so that the
germ floor can be taken up in its individual parts and easily cleaned. The under
Hoor consists of prepared cement blocks of corresponding size and thickness
which are laid in rows, and between each two rows of blocks a space is left which
forms an air channel. These air channels are closed at one end and are connected
at the other end with a main air channel which is arranged at the front of the
malt floor.
In each of the air channels is arranged a water pipe of corresponding size which
is closed at one end whilst the other end opens into a main water pipe which is
attached to the water supply or conduit.
The water pipes are perforated inside the air channels and the perforations are
fitted with a water spreading arrangement so that the finely spread water saturates
the air flowing into the air channels.
After the soaking is finished the grain is heaped up equally on the germ floor.

page_text: The influx of the air is affected by means of fans blowers or other suitable
apparatus driven in the main air channel which latter is connected with a
cooling vessel in which is fitted a system of pipes. The inflowing air is driven
through the cooling vessel which is filled with ice and salt and cools the air to
about 5° or Go below zero Reamur. If more salt be added with powdered chalk a
temperature of 9° to 10° below zero can be attained. The air and water supply
can be regulated for a given floor space as required.
The main air channel has for its object to take up the nir, to distribute it in the
branch air channels and serves at the same time as a collecting channel or conduit
for carrying off the water.
The branch air channels are covered over with perforated sheet iron plates
which rest on both sides of the channel loose on ledges.
The inflowing air distributes itself from the main air channel in the branch
air channels, and enters the space between the under floor and the germ floor,
passes through the perforations in the latter, and penetrates the grain heaped
up on the same.
The branch air channels serve at the same time to receive and run off the water
falling through from above and which flows off in the collecting channels.
The stone block under floor is moistened through by the circulating water and
thus remains continually moist and cool without the air passing through the grain
losing by giving off moisture to the stone floor, as the water spreading serves to
moisten both the stone floor and the inflowing air.
The apparatus is connected with the poles of a dynamo; the germ floor is
connected to the positive pole and the moist heaped up grain forms an intermediary
conductor, the gases (carbonic acid) developed during the germinating process can
clear off without hindrance as the negative terminal is formed by means of a wire
netting laid on the grain. The wire netting lying on the grain is arranged movably
in order to allow the grain to be turned over without hindrance.
The influence of the electric current on the germinating process is of great
importance aud advantage for a quick and thorough germination of the grain, every
living germ of organism is destroyed and the formation of fungus or mould
prevented.
Again all danger to the workmen employed in the malthouse is prevented by
non conducting apparatus being so arranged that by treading on the germ floor the
current is interrupted.
A system of pipes arranged over the malthouse carries off the air impregnated
with carbonic acid gas in proportion to the amount of fresh air introduced, whereby
the indispensable oxygen for the germination is brought in.
The apparatus differs from apparatus already known by the channels being all
open aud easily cleaned and by the grain being covered over by a wire netting
which is connected to the negative pole of a dynamo and by connection of the
germ floor with the positive pole, whereby the grain is brought between the two
poles and is thus influenced by the penetration of the electric current, which
hastens the germinating process by the decomposition of the carbonic acid and
moisture contained in the grain.
By the possibility of regulating the temperature of the malting it is possible to
malt all the year round.
The turning of the grain can be effected by automatic or band malt turners.

I, FREDERICK WILLIAM GOLBY, of 36 Chancery Lane, in the County of
Middlesex, Patent Agent, do hereby declare the nature of this invention and
in what manner the same is to be performed, as communicated to me by
Johann Jungbluth, of Friesenwall 86, Cologne a/R, Germany, to be particularly
described and ascertained in and by the following statement :-
In the germinating process of malting, the grains take up oxygen, it is therefore
necessary in addition to the presence of sufficient moisture and air, to supply the
germinating grains with a sufficient quantity of oxygen to enable the process of
germination to be properly carried out. As it is scarcely possible by steeping
and soaking to furnish the grains with the entire quantity of moisture which
is necessary to a complete and regular germination, it is necessary in the first
place to construct a malting apparatus by which the requisite air and moisture
can be supplied in a regular manner to the grain during the germination thereof.
The success of this operation is dependent principally on the conditions of
the malting apparatus which must be as far as possible independent of outside
influences.
The object of the present invention is the construction on the above mentioned
principles of malting apparatus in such a manner that the malt stuff heaped up in'
regular quantities on a comparatively small floor surface can by means of electricity
be quickly brought to germination, and the temperature and also the degree of
moisture of the malt stuff under treatment reliably adapted to the conditions
favourable at the time to the germination.
To carry out the principles above indicated it is necessary to so construct the
apparatus as to produce in the inside of the same a cool moist air which produces
an equal temperature ou the soaked grain thereby preventing it from changing
colour, and allowing all the grains to germinate equally.
The apparatus which forms the subject of this invention is built up of two separate
floor beds one above the other.
The invention is illustrated in the accompanying drawings.
.
Fig. 1 is a plan of a malting apparatus constructed according to this invention,
Fig. 2 as a side clevation, and Fig. 3 a longitudinal section of same.
Figs. 4 to 6 are details of the apparatus drawn to a larger scale.
The germ floor A consists of quadrilateral plates a of tin coated sheet iron or
similar metal, which are furnished with fine narrow pierced openings. These
plates a are fastened to a grid formed of frames a' which lie free on the under
floor B so that between the said under floor B, and the germ floor A is formed a
free space C so that the germ floor can be taken up in its individual parts and
easily cleaned. Fig. 5 is a transverse section through the two floors A and B taken
at right angles to Fig. 3. The under floor B consists of prepared cement blocks b
of corresponding size and thickness which are laid in rows, and between each two
rows of blocks a space is left which forms au air channel d. These air channels d
are closed at one end and are connected at the other end with a main air channel d'
which is arranged at the front of the malt floor. In each air channel dis
arranged a water pipe g of corresponding size which is closed at one end whilst
the other end opens into a main water pipe g', which is attached to the water
supply or conduit,
The water pipes g are perforated inside the air channels and the perforations aro
fitted with a water spreading arrangement so that the fiuely spread water saturates
the air flowing into the air channels.
After the soaking is finished the grain is heaped up equally on the germ Hoor.
The influx of the air is effected by means of fans, blowers or other suitable

page_text: apparatus driven in the main air channel d' which latter is connected with a cooling
vessel F in which is fitted a system of pipes. The inflowing air is driven through
the cooling vessel which is filled with ice and salt and cools the air to about 5° or 6°
below zero Reamur. If more salt be added with powdered chalk a temperature
of 9° to 10° below zero can be attained. The air and water supply can be regulated
for a given floor space as required.
The main air channel has for its object to take up the air, to distribute it in the
branch air channels and serves at the same time as a collecting channel or conduit
for carrying off the water.
The branch air channels d are covered over with perforated sheet iron plates k,
which rest on both sides of the channel loose on ledges.
The inflowing air distributes itself from the main air channel d' into the branch
air channels d, and passing through the perforated plates k on the latter, enters the
space C between the under floor B and the germ floor A, and penetrates the grain
heaped up on the same.
The branch air channels d serve at the same time to receive and run off
the water falling through from above and which flows off in the collecting
channels.
The stone block under floor B is moistened through by the circulating water
and thus remains continually moist and cool without the air passing through the
grain loosing by giving off moisture to the stone floor, as the water spreading serves
to moisten both the stone floor and the inflowing air.
The apparatus is connected with the poles of a dynamo; the germ floor is
connected to the positivo pole and the moist heaped up barley forins na inter-
mediary conductor, the gases (carbonic acid) developed during the germinating
process can clear off without hindrance as the negative terminal is formed by
means of a wire netting laid on the grain. The wire netting lying on the
grain is arranged movably in order to allow the grain to be turned over without
hindrance.
The influence of the electric current on the germinating process is of
great importance and advantage for a quick and thorough germination of the
grain, every living gerin of organism is destroyed and the formation of fungus or
mould prevented.
A system of pipes arranged over the malt-house carries off the air impregnated
with carbonic acid gas in proportion to the amount of fresh air introduced, whereby
the indispensable oxygen for the germination is brought in.
The apparatus differs from apparatus already known by the channels being
all open and easily cleaned and by the grain being covered over by a wiro netting
which is connected to the negative pole of a dynamo, and by connection of the germ
floor with the positive pole, whereby the grain is brought between the two poles
and is thus influenced by the penetration of the electric current, which hastens the
germinating process by the decomposition of the carbonic acid and moisture
contained in the grain.
By the possibility of regulating the temperature of the malting it is possible to
malt all the year round.
The turning of the grain can be effected by automatic or hand malt turners.
The malting apparatus herein described takes into account every requirement
of a rational malt germination, inasmuch as three times the amount of malt
may be prepared in half the time on a smaller floor surface than an ordinary
malt floor with the greatest profit and advantage. On account of its cheaper
method of working the apparatus is preferable to all others and not to be
excelled.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be parformed, I declare that what I
claim is ;-
The construction of an electric malting apparatus distinguished by the building

page_text: of two floors one above the other with space between, of which the upper floor
rests on frames and is constructed of perforated metal plates, which latter are
connected to the positive pole of a dynamo or other electric generator, the under
floor of the apparatus being formed of stone blocks which are arranged in rows
with channels formed between the rows said channels being covered with removable
perforated plates and serving on the one hand for the reception of the pipes fitted with
the water spreading arrangement, and on the other hand for the conveyance of the
specially prepared air and the efflux of the collected water, the grain being covered
with a wire netting insulated from the germ floor, and connected to the negative
electric pole substantially as and for the purpose hereinbefore described and
illustrated in the accompanying drawings.
