PROVISIONAL SPECIFICATION
New or Improved Process for Manufacturing Feeding Cakes for
.Animals.
We, JAKOB KRAUS and ERNST DEBO, both Engineers, of 5, Allerheiligenstrasse,
Cologne-on-Rhine, Germany, do hereby declare the nature of this invention to
be as follows;
The great advantages of the use of solid feeding cakes for transport and preser-
vation have given rise to different processes which, however, owing to the com-
plicated mode of manufacture can not be put into practice.
'
The trials which have hitherto been made are of two kinds; on the one hand
the doughy mixtures forming feeding cakes are baked in the form of bread, on
the other hand liquid agglutinants or water are added to the meal, the said meal
being afterwards compressed mechanically and finally subjected, to a drying pro-
cess. The first offer the inconvenience of being of an elevated price, the second,
on the contrary, without taking their complicated manufacture into consideration,
are liable to be spoiled when insufficiently dried.
The present invention therefore dispenses with all addition of moist substances
or agglutinants.
Oats or other sorts of corn and vegetables are crushed and afterwards put, with-
out any other addition, into a heater, where they are subjected to a temperature
which is as uniform as possible, of about 50° C., so that the moisture contained in
the corn commences to evaporate and to re-act on the amylaceous matter and the
gluten.
The mixture thus heated is transferred into a press which is also heated where
it is pushed by a piston through a conical hopper and reduced in volume, so that
it leaves the press in the form of a solid bar. This bar is then cut in pieces of a
determinate weight, the said pieces undergoing no other treatment. The mixture
of the feeding cakes of different sorts of corn and vegetables is proportionate to the
ration desired.
The feeding cakes may be manufactured according to the same process with bran
or other corn wastes.
The distinguishing feature of the invention is the suppression of all addition of
moist substances, the result being that the manufacture is exceedingly simple and
that the spoiling of the cakes, through acid or mouldiness, is completely suppressed.

page_text: in what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement;-
-
The great advantages, such as easy transport and better preservation, which
result from the use of solid feeding cakes for animals have given rise to different
processes for manufacturing the same. These processes, however, on account of
the complicated mode of manufacture, have not been put into general practice.
The methods of manufacture which have been adopted up till now are of two kinds,
one in which a pasty mixture is prepared and formed into cakes and then baked
in a suitable form of oven, and the other in which there is first added to the grain
or the like any suitable agglutinative liquid and the mixture is then compressed
and finally subjected to a process of desiccation. The first method has this objection
that it makes the food more expensive, whilst, the second method, apart from the
elaborate process of manufacture, has the objection that the product is liable to
decompose when insufficiently desiccated.
The present invention has for its object to do away with the addition of moist
or agglutinative substances during the manufacture of the cakes.
In carrying out the invention the oats or other kind of grain and leguminous
substances are ground and, without any other addition, put into a heater where they
are subjected to a temperature, which is kept as uniform as possible, of about 500,
so that the moisture contained in the grain begins to evaporate and in doing so
reacts on the amylaceous matter and the gluten.
The mixture thus heated is then put in a press equally heated where it is
pushed or compressed by means of a piston rod through a conical hopper and
thereby reduced in volume so as to leave the press in the form of a solid bar. This
bar is afterwards cut into pieces of a certain weight which do not require to be
subjected to any further treatment.
The mixture of grain or leguminous matter forming the cakes may be made up
in any desired proportions.
The cakes may, if desired, be manufactured from bran or other refuse from the
mill.
The press is heated from the outside.
The characteristic feature of the invention is that, under this process of manu-
facture, the addition of moist substances is unnecessary, with the result that not
only is the manufacture rendered exceedingly simple but liability of the cakes
becoming corrupted through acidity or mildew is entirely overcome.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we consider novel and desire to claim is ;-
1. A process for the manufacture of cakes from grains and leguminous sub-
stances without the addition of moist or agglutinative substances, in which the
crushed corn, in order to evaporate its natural moisture, is subjected to a moderate
heat and then compressed into the form of solid cakes in a press which is heated
externally, substantially as hereinbefore described.
2. The manufacture of cakes from bran or other mill refuse according to the
process claimed in Claim 1.
