PROVISIONAL SPECIFICATION.
An improved Process of Manufacturing Food for Animals.
We, STEFAN HAGYI-RISTIC, of 24 Wollzeile, Vienna I, Austria, and BRUNO
SEELIGER, of 32 Hetzgasse, Vienna III, Austria, Manufacturers do hereby declare
the nature of this invention to be as follows:-
This invention relates to a method of producing preserved grain fodder of all
kinds, and it has for objects to render such fodder capable of being kept free from
decay for a long period and to make it suitable for feeding-purposes in the form of
cakes or tablets.
According thereto, the cleaned fodder is maintained during the whole period of its
treatment that is to say from the commencement of the treatment until the final
product is obtained-at a temperature that effects the expulsion of the moisture
contained in the grains, so that the grain-fodder when mixed with a dry binding agent
and formed into cakes or tablets by great pressure, itself accomplishes the required
moistening of the said binding agent and the combination therewith and that by
the time the pressure is removed the fodder will be perfectly dry. By this means
the more or less liquid binding agents heretofore required, and the drying of the
finished cakes can be dispensed with and duration of the treatment considerably
shortened.
The oats, barley, or other grain-fodder to be treated according to this invention, is
first cleaned in a suitable machine and is then placed in a mixing chamber, either in
an uncrushed state or after having been moderately crushed between rolls, the said
mixing-chamber being heated by steam or in any other suitable manner.
In this mixing-chamber the fodder is brought to a temperature (30° to 80° C.), at
which the moisture contained in the fodder will be expelled. As soon as this
expulsion begins, there is added a dry powdered binding agent, which is then, during
a short time, mixed in the heated mixing-chamber with the grain-fodder. This
binding agent is, by preference, one which itself contains nutritious matter, or which
at any rate will not diminish the nutritive value of the grain-fodder such for instance
as bruised barley, rice-flour for feeding, bean-flour and bran. The amount of the
binding agent depends upon the desired degree of compactness of the cakes or
tablets. Suitable proportions generally speaking are from 1 to 30 parts by weight of
the binding agent to 100 parts by weight of grain-fodder.
If desired, a liquid binding agent as for example, a sugar solution, an amylaceous
fluid or a mucilaginous, gelatinous, glutinous, or gummy substance-may be added to
the extent of a few parts per cent.
The moisture expelled from the grains effects, during the mixing-operation, the
coherence of the grain-fodder and the binding agent and the formation of a plastic
mass, which is put into a hydraulic or other suitable press the moulds of which
should be previously heated, and is then submitted to considerable pressure say of
150 atmospheres or more, whereby it is compressed into cakes or tablets.
This great pressure in heated moulds produces a considerable reduction of the
volume of the mass and also completely dries the grain-fodder; so that supplementary
drying and ventilating appliances are not absolutely necessary, and can be dispensed
with.
Instead of oats, barley and other grain-fodder, there can be produced by the same

page_text: method also different mixtures of oats or other grain-fodder with leguminous fodder
and with industrial feeding-material, spent maize, malt returns, etc.

An Improved Process of Manufacturing Food for Animals.
We, STEFAN HAGYI-RISTIC, of 24 Wolizeile, Vienna I, Austria, and BRUNO.
SEELIGER, of 32 Hetzgasse, Vienna Ill, Austria, Manufacturers, 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 relates to a method of producing preserved grain-fodder of all
kinds, and it has for objects to render such fodder capable of being kept free from
decay for a long period and to make it suitable for feeding-purposes in the form of
cakes or tablets.
According thereto, the cleaned fodder is maintained during the whole period of its
treatment that is to say from the commencement of the treatment until the final
product is obtained-at a temperature that effects the expulsion of the moisture
contained in the grains, so that the grain-fodder, when mixed with a dry binding.
agent and formed into cakes or tablets by great pressure, itself accomplishes the
required moistening of the said binding agent and the combination therewith and
that by the time the pressure is removed the fodder will be perfectly dry. By this
means the more or less liquid binding agents heretofore required, and the drying of
the finished cakes, can be dispensed with and the duration of the treatment consider-
ably shortened.
The oats, barley, or other grain-fodder to be treated according to this invention,
is first cleaned in a suitable machine and is then placed in a mixing chamber,
either in an uncrushed state or after having been moderately crushed between
rolls, the said mixing chamber being heated by steam or in any other suitable
manner.
In this mixing-chamber the fodder is brought to a temperature (from about 30°
to 80° C.), at which the moisture contained in the fodder will be expelled. As soon as this
expulsion begins, there is added a dry powdered binding agent, which is then, during
a short time, mixed in the heated mixing chamber with the grain-fodder. This
binding agent is, by preference, one which itself contains nutritious matter, or which
at any rate will not diminish the nutritive value of the grain-fodder-such for
instance as bruised barley, rice-flour for feeding, bean-flour and bran. The amount
of the binding agent depends upon the desired degree of compactness of the cakes or
tablets. Suitable proportions generally speaking are from 1 to 30 parts by weight of
the binding agent to 100 parts by weight of grain-fodder.
If desired, a liquid binding agent-as for example, a sugar solution, an amylaceous
fluid, or a mucilaginous, gelatinous, glutinous, or gummy substance-may be added to
the extent of a few parts per cent.
The moisture expelled from the grains effects, during the mixing-operation,
the coherence of the grain-fodder and the binding agent and the formation of a
plastic mass, which is put into a bydraulic or other suitable press the moulds
of which should be previously heated, and is then submitted to considerable
pressure say of 150 atmospheres or more, whereby it is compressed into cakes or
tablets.
This great pressure in heated moulds produces a considerable reduction of the

page_text: volume of the mass and also completely dries the grain-fodder, so that supplementary
drying and ventilating appliances are not absolutely necessary, and can be dispensed
with.
Instead of oats, barley and other grain-fodder, there can be produced by the same
method also different mixtures of oats or other grain-fodder with leguminous fodder
and with industrial feeding material, spent maize, malt returns etc.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what
we claim is :-
The herein described method of manufacturing preserved grain-fodder, as well as
preserved mixtures of the grain with leguminous fodder and with industrial feeding
materials whilst simultaneously reducing the volume thereof, the said method
consisting in heating the previously cleaned and, in case of need, crushed grain-
fodder to a temperature that will effect the expulsion of the moisture therefrom, mixing
the said fodder at the same time with a dry binding agent and also if desired with a
liquid binding agent of the described nature, and then pressing the mixture in heated
moulds under great pressure into the shape of cakes or tablets, substantially as set
forth.
