Improvements in Extracting Oil from Oil-containing Plants and
Fruits, and in the Production of Fodder from the Residual
Matter.
We, WILHELM SPINDLER of 5 Muhlstrasse, Chocolate Manufacturer and CARL
STAUTZ of 24 Lautenschlägerstrasse, Merchant, both of Darmstadt, in the German
Empire, do hereby declare the nature of our said invention to be as follows:-
The object of our invention is to extract and utilise the oil from oil-containing
plants, fruits, seeds, kernels, and the like, by pressure; and treating the residue with
a solution of salt, consisting of from 2 to 5 parts of salt (by weight) to 100 parts of
water.
Instead of a saline solution, a solution of sugar, syrup, or the like, may be used,
but the increased expense is objectionable, and the fodder is inferior to that produced
by the saline treatment.
One method of carrying out our invention consists in subjecting the oil containing
plants, fruits, and the like, to suitable pressure in a crushing mill or press, whereby
the oil is expressed therefrom. We then add the saline or saccharine solution to
the remaining (more or less) solidified matter, and boil or otherwise treat the same
to complete its préparation as fodder.
Preferably however we add the saline or saccharine solution to the raw material
previously to the application of pressure, and boil the same together in a suitable
vessel for a short time. The compound is then placed in a crushing mill or press,
from which the salt or other solution flows at first of a milky colour, under slight
pressure, together with almost the whole of the soluble portion of the material.
Upon increasing the pressure the oil is thereby expressed. This oil may be
allowed to float upon the salt or other solution, which latter may be readily drawn
off from under the oil. The compressed material is then removed and allowed to
dry, for use as fodder.

COMPLETE SPECIFICATION.
Improvements in Extracting Oil from Oil-containing Plants and
Fruits, and in the Production of Fodder from the Residual
Matter.
We, WILHELM SPINDLER, of 5 Muhlstrasse, Chocolate Manufacturer, and CARL
STAUTZ, of 24 Lautenschlägerstrasse, Merchant, both of Darmstadt, in the German
Empire, do hereby declare the nature of our said invention and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement :-
The object of our invention is to extract and utilize the oil from oil-containing
plants, fruits, seeds, kernels, and the like, in an improved manner whereby oil is
less expensively obtained therefrom and the fodder is of a superior quality.
In carrying out our invention we subject the oil-containing plants, fruits, and the
like to suitable pressure. The crushed plants, fruit and the like are then mixed
with a saline solution and passed through a crushing mill or press, from which the
TD 07

almost the whole of the soluble portion of the material. Upon increasing the
pressure the oil is thereby expressed. This may be allowed to float upon the saline
solution which latter may be readily drawn off from under the oil. The compressed
material then removed and allowed to dry, for use as fodder.
We prefer however to cook the fruit, seeds etc. with the saline solution previous
to being subjected to pressure for extracting the oil.
The saline solution consists of from 2 to 5 parts of salt (by weight) to 100 parts
of water; a solution of sugar, syrup, or the like, may be used in some cases, but
the increased expense is objectionable, and the fodder is inferior to that produced
by the saline treatment.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. Extracting oil from oil-containing plants, fruits, seeds, kernels and the like, by
first crushing the plants etc. and mixing therewith saline or sugar solution, the
whole then being again subjected to pressure whereby the oil is expressed therefrom
substantially as described.
2. Extracting oil from oil-containing plants etc., by first cooking the plants, fruits
and the like with the solution and then subjecting the compound to pressure,
substantially as herein before described.
3. The application and use of a saline or sugar solution, substantially as and for
the purposes herein before described.
4. The method of producing fodder, substantially as described.
5. The improvements in extracting oil from oil-containing plants, fruits, seeds,
kernels, and the like, and in the production of fodder from the residual matter
substantially as herein before described.
