Description
The invention rela-tes to foods-tuffs and most specifically has advantageous applica-tions in the feeding of domestic animals such as dogs and cats. The invention has for its object a new produc-t and its preparation method.
Such a product and me-thod are also applicable -to other animals as well as to human beings~ and may also be applicable in other technical fields~ e~g. -the manufacture of proteins~
fertilizers and manures.
Until now, meat containing products such as petfood for domestic animals are obtained by crushing certain meat pieces.
Such meat pieces have to fulfill several conditions:
- they must not contain too hard pieces so a~ not to damage the grinding mill, - they must no-t be too soft so as not to obstruc-t the mill by stuffing, - they must not contain matters not usable as food-stuf~, since all -the crushed product is used in the final food product J
Another drawback of produc-ts obtained in grinding mills relates to the aspect of the product, very finely ~ivided.
Such a pa-te is no-t always favourable, for coTmnercial reasons and for grounds in connection with animals' appetency, The foods-tuff according to the invention has a fibrous structure, the cornponent being several millimeters long, and pos-sibly reaching 2 centimeters in some cases, what is a very good feature for the aspect as well as for the appetency. Nevertheless, it does not contain any hard or dangerous component~ e.g. hair, teeth or the like.
The preparation method according to the invention allows to use cheap raw materials, what is not possible in grinding or crushing.
It is an object of the invention to provide a new product useful for preparing a foodstuff, for human beings and anirnals, more specifically domestic animals, such as dogs and cats.
It is another object of the invention to provide a new me~hod for preparing such a useful product.
According to the invention~ there is provided a method ~ in which quarters of meat or whole animals arc subjected to a :.~; . . .. : .
.. .
-. : , . ' ,.. ' ' . ~ :
. .
mechanical trituration or mastication simultaneously with a crushing~ w~ile being under a heavy pressure in a phase sepa~
ration press.
More specifically~ the invention relates to a method ~or preparing a foodstuff having a heterog~eneous composition and a fibrous structure in the forrn of coherent filaments of substantial length, comprisingo simultaneously crushing and compressing whole or coarsely broken animal, fish or crustacean raw material in a phase separation press, with at least one advancing punch in a closed chamber filled with the raw material under a pressure sufficient t~ compress and masticate soft foodstuff matter and crush hard matter in the raw material without substantially destroyiny the cohesion of the desired food cornponents of the raw material and to e~trude the masticated soft matter from the press, the closed chamher and/or punch being provided with exit channels through which the masticated matter is e~truded, and extruding the masticated soft foodstuff matter from the press to obtain a product having a hetero~eneous cornposi-tion and containing the desired food components in the form of coherent filaments of substantial length, the undesirable components of the raw material remaining in the portion resi~ting to e~trusion.
The present invention also relates to a foodstuff having a heterogeneous composition and a fibro~s structure in the form of coherent filaments of substantial length, and prepared starting from whole or coarsely bro]cen animal, fish or crustacean raw material by a process as defined ahove.
Phase separation presses of this kind have already been proposed in patent application No. 292,407 filed on De-cember 5, 1977 in Canada hy the applicant, to be applied more . - . .
particularly in the treatment of household garbage.
In such a pressl in a closed, so-called pressure cham-ber supplied with the matter to be treated, said matter is tri-turated, crushed and compressed to several hundred bars by causing at least one punch to advance in the pressure chamber, and at -the same time, the liquid or pasty phase of the matter thus masticated and compressed is made to flow through cali-~rated passages opening in the pressure chamber or in the lateral face of the punch. m en, the punch is withdrawn and the recess made by the penetration of said punch ln the mass of matter in the pressure chamber i5 reabsorbedl reducing the volume of the pressure chamber, and the punch is again made to penetrate the mass of matter. The sliding or lateral face of the punch comprises longitudinal collecting grooves into which open a plurality of transverse channels, said collecting groo-ves opening into a chamber for recovering the si-fted matter~
The product extracted in the grooves o-f the punch is the new product according to the invention~
In the machines of this kind, providing phase separa-tion according to the extrusion capacity of the components oftreated matters, the softest matters are expelled out of -the mass in the form of coherent filaments of more or less great length. During the compression work there does not occur any-th1ng like the intense stirring caused by the conventional crushing~ It ensues two essential features for the product:
the presence of many coherent components not destroyed, and ; a rather heterogeneous composition of the mixture.
It-is interesting to draw advantage of -these new ~ea-tures in view of preparing such products with no equivalent in the consumer's market, owing to the cost of human intervention.
According to another feature of the invention, at ~' -3a-, least par-t of the various componen-ts oF -the final produc-t are mixed in their raw form before compression. The meat containing portion is used in its simples-t possible form so as to reduce the preparation costs, and so is -the possibly present vegetable portion in many cases. The aspect of the final mixture allows to see the different componen-ts and no hard or dangerous components, such as bone or tooth splint~rs, fish bones, hair or the like, can be seen in the product.
Another advantage of the method of the invention is to be seen in that it is possible -to use pieces of high nu-tritious grade, which, a]-though being of low cost, are not, or unproperly, used presen-tly, due to the technological difficulties.
The invention will be more fully understood by reference to the detailed description of the following examples.
Example 1 Whole animalsl heads, more particularly non prepared sheeps heads, were treated under compressionO The extrudable collected portion is substantially sim~lar to head pate used by human beings. The portion resisting to extrusion, ejected out of -the press in the form of a lump~ contains the skin with the hair, the bones, the teeth and a low content or cartilage and meat.
Animals feet~ more precisely pig s and ox s feet were treated without any special preparation, either frozen or fresh, A red meat is obtained, with a high amoun-t in soft carti-lage in the case of pig s feet. In the press, there remain the skin, bones and hoof s horn.
Animals foetus and still~born ~nimals, mostly in form of whole beasts, were treated in the same way. The results are similar to those o~ exa~ple 1.
~ .
Little animals were treated without being CUt out, more specifically chickens and rabbits~ The skin, with feathers and hair remain in the dry portion~ as well as the beaks~ teeth, claws~ and naturally the bo~es as in the other examples.

5.-Example ~
Long bones, and more speci:Fically those containingmarrow, have been treated. The ~ilarrow is ex-trac-ted in form of long filaments retaining a certain cohesion. Marrow is also extrac-ted in the cases of preceding examples and gives to -the final product an interes-ting physical structure.
In the case of the five foregoing examples, -the dry remaining portion is advantageously treat~d through thermal way for obtaining bone-black.
Fishes, and more particularly fishes wi-th large heads and important bones, what reduces their commercial value, or what remains from fishes after the fillets have been rernoved, were treated under comp~ession. In this case also~ heads, bones and part of the skin remain in the dry portion.
Exam~le 7 , e.g. crabs, after their most valuable parts such as the nippers have been removed, are -treated in the same way. The extrac-ted meat ob-tained from uncured animals remains fairly firm, with a fibrous struc*ure. The remaining shells are trea-ted after that with interest for giving a plastic material with high grade characteristics and wholly bio-degradable.
~ .
The final petfood provided for animals is a mixture of ~arious components, some of which are vegetable in moSt of the cases. These various components were mixed before being treated by compression and phase separation. The product obtained in the ~luable portion has a favourable aspect since the parts of the various components can easily be seen in form of pieces of several millimeters.
Certain products present some difficulties in proceed-ing. The phase separation is much easier in some cases by means of a curing, complete or partial, before compression.
;, ~ .
Certain produc-ts can be wholly used as foodstuff. In this case, the press is used instead of a grinding mill~ and the product obtained has a be-tter aspect.
~.

6.-Many other products can be treated in the same wayfor obtaining foodstufs as well for human beings as for animals.
It will be understood that this invention is suscep-tible to modification in order -to adapt to different usages and conditions, and accordingly it is desired to cormprehend such rnodification wi-thin the invention as may fall within the scope of the appended claims.
