A New Process for Making Consistent Fish-fat, Train and other Oils
by Means of Compressed Oxygen.
"
I EWALD OPDERBECK, Chemist, of Cologne, Josefstrasse No. 42, in the Province
of Rhineland, Germany, 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 has reference to a new process for making consistent fish-fat, train
and other oils by means of compressed oxygen as herein after more particularly
described with reference to the annexed sheet of illustrative drawings thereof.
Already for a long time it has been the custom in order to oxidize fish-fat, train
and other oils to bring them on a great surface into contact with atmospheric air or
to treat them with compressed heated air or to decompose them by the help of
substances which transinit oxygen as for example copper salts etc.; but no state of
aggregation was ever obtained in the oily fluids but only watery emulsions of the
same.
By my new process perfectly firm consistent fats are obtained and in the following
manner:
The oil is heated by means of a serpentine up to from 90 to 110° C. in the tank,
marked A in the drawing and then passes into the tank B of a conical shape and
narrowing from bottom to top. In the inside of this tank there are one or more
pipes D, adapted to the shape of the tank-casing, branching off from an oxygen
supply-pipe C which passes vertically downwards into the tank through the cover
and fitted at its upper end with pully-mechanism. These pipes Dare provided with
fine holes to allow the oxygen to stream out and on account of this and the rotation
of the pipe C which serves as axis, act simultaneously as oxygen diffusers and
agitators.
By the rapid and close contact of the fine oxygen spray thus attained with all the
molecules of the oily fluid in the tank B, a uniform consistent fat is obtained. The
oxygen is supplied to the pipe C under high pressure from the bottle E (steel
cylinder) filled with compressed oxygen.
As some of the oils which have been made consistent by this process after some
time again deposit about 2-3 per cent. of oil, a correspondingly small amount of
animal, vegetable or mineral hard fat as wax, paraffine etc. is mixed with such oils
in the tank A thus preventing any deposit.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :
1) The process of making fish-fat, train & other oils consistent by the direct
application of compressed oxygen by heating them up to from 90°-110° C. in
conical tank which narrows towards the top, by means of one or more rotating tubes
having a shape of agitating arms emitting the oxygen through little holes and
bringing these fats, oils etc. into the quickest and closest contact with the oxygen,
which flows in under high pressure and in a very fine stream.
2) For certain oils, which some time after becoming solid are liable to again deposit
a slight percentage in a fluid form, the same process with the modification, that a
correspondingly larger or smaller amount of animal, vegetable.or mineral hard fat
as wax etc. is added to the oils, thus preventing any later depositing of fluid oil.
