COMPLETE SPECIFICATION.
Improvements in or relating to the Smoking of Salmon and the
like, and in Apparatus therefor.
I, CARL WALDEMANN, of Cöslin, in the German Empire, Commercial Councillor,.
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 :--
My invention relates to improvements in the process of smoking salmon and
the like.
These fish have been hitherto invariably hung up in the split condition and
exposed to the smoke. This method, however, possesses various drawbacks which
have led the operators to cover the split fish on the fleshy side with bladder,
parchment paper, or the like substances, and then to expose them to the action of
the smoke, placed upon suitable frames. The results thus obtained were certainly
more satisfactory than before, but there still remained a drawback in that this
method requires for its application fish of considerable size; on the one hand because
small fish would when split have too little thickness of flesh, and because on the
other hand they would also too soon become dry, in consequence of which they
would not come up to the requirements of the market.
By my improved process I am able to treat both large and small fish in the
undivided condition in such a manner that they yield a product which corres-
ponds to all the requirements of the trade equally as well as large split fish.
These fish are taken in hand before they have been slit up and are then cleansed.
The interior of the fish is then covered in the wellknown manner with bladder,
parchment, or the like. The skin of the fish may be also wholly or partially removed,
but it is then requisite to cover such places with an artificial covering. The fish are
then placed upon smoking frames A (Figures 1 2 and 3) formed of wood, wire, tubes,
or wicker work and brought into the smoking chambers exposed to the action of
the smoke. In order to render this action as perfect as possible, the frames have the
shape of a roof or a saddle. The fish are placed thereon in such a manner that the
ridge of the frame comes to lie under the back of the fish, and the sides thereof hang
down against both sides of the frame. The smoke can in this manner easily
penetrate to the interior, as well as reach the exterior of the fish, and smoke the
same throughout.
The under sides of fish treated in this manner can be again bent together before
packing and tied up whereby the same again return to their natural shape.
In consequence of the fact that even small fish may be smoked by this method
the same can be advantageously used, whereas they are not suitable for smoking
in the split state, because on the one hand they dry too rapidly, and on the other
hand the thin halves of the fish would not admit of a satisfactory slicing.
A further advantage of the present process consists in that the thick and tough
skin of the fish can be entirely or partially removed and in place thereof the covering
of bladder, parchment, or the like be made use of which offers no resistance to the
knife, and consequently admits of the easy cutting up of the fish without any danger
of tearing the same.

herein described, and Figures 2 and 3 shew respectively the same frame in side view
and in section with a fish in position thereon.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is :-
1. The improved process for preparing and smoking salmon and the like,
characterized by the treatment of the fish in the undivided condition, partly or
wholly deprived of its skin, and covered at the under side, and at the places deprived
of skin, with bladder, parchment, or the like, and the smoking of the same upon
saddle shaped frames of wood, wire, tubes, or wicker work, whereby even small fishes
can be suitably prepared for the market.
2. The improved apparatus for the smoking of fish such as salmon and the like
according to the process set forth in Claim 1, said apparatus consisting of a roof or
saddle shaped frame of wire, wicker work, tubes, or wood upon which the fish is
arranged in such a manner that the ridge of the frame lies in the aperture of the
fish whilst the sides thereof lie flat against the sides of the frame.
