Description
3t~
B~C~GROUND OF THE INVENTION
Field: The invention is in the field of apparatus for extruding composite food products, for exa.mple, consolidating and sha.ping normally unattractive and commercially una.ccepta.ble pieces of flesh a.nd fat into 5 attractive and commercially a.ccepta.ble meat shapes.
State of the Art Loa.ves and other shapes of meat materials have long been prepared by ma.nually arranging different meat pieces together9 with or witho~t binders, and by consolidating such pieces under pressure to form a product which is commercially attractive and can be 10 sliced. Some attempts have been ma.de heretofore to simulate cuts of meat, such as bacon slabs by this technique. Also, ground or emulsified mea.t a.nd fat mixtures have been extruded and cut to simulate known commercia.l cuts. Various types of app~ratus ha.ve been developed here-tofore for extruding different ma.terials, such as soap of differen~ colors, 15 and consolidating the different ma.terials as a final unitary productO .
Objective: The present invention has a.s its primary objective to eliminate time consuming a.nd expensive ma.nua.l fabrication of commer- .
cially a.ccepta.ble meat shapes having desirable striation of different meat ormeatandfatcha.racteristics, especiallysimulatedbaconslabs, by 20 apparatus that effectively accomplishes the purpose and can be quickly a.nd easily disassem~led for cleaning and rea.ssembled for further use~
BRIEF SUMM~RY OF T~IE INVENTION
In accomplishing the objective of the invention, ingredients for the respective striations are fed to and extruded through different portions 25 of a compound die. The respective extrusions are interleaved as they emerge from the different portions of the die into a common discharge area thereof, where they a.re comp:ressed into a coherent column and discha.rgecl as a continuous colurnn. The column may have a.ny desired shape, a.s, For exa.mple~ a slab, and is cut tra.nsversely in desired lengths to :Eorm the fina.l product, e g., ba.con slabs.
Suitable binders, for e~ample, mineral salts that chemically 5 affect superficial surfaces of meat to provide protein adhesive coatings thereon, are usually included with meat pieces or fragments fed to the die, thereby firmly binding such pieces or fragments together under the pressures encountered cluring extrusion. :~
The opera.tion is a.dva.ntageously carried out under conditions 10 of deaera.tion of the feed materials, thereby insuring against the occurrence of undesira.ble voids in the resulting product.
When the product is ba.con, the die may be configurated to pro-duce striations of random thicknesses and positions closely simulating those of natura.l bacon. The extruded column rna.y be cooled preparatory 15 to the imr~lediate slicing of bacon strips from the column, or the extruded column may be exposed to microwaves -Eor prot:ein coagulation a.nd then case hardened and tempered in the usual :manner for slicing.
The apparatus includes an extrusion assembly comprising a die ha.ving a housing within which extend a plurality of individual die conduits 20 from a. front wa.ll provided with openings lea.ding into the die conduits. The space surrounding the die conduits within the housing form die passages interleaved with the die conduits. Means are provided for extruding a food material through the front wall openings and through the die conduits into a convergent discharge conduit removably a.ttached to the housing. Separ-25 able supply conduits connect a pressure source of supply of a differentfood material with the housing at opposite sides thereof as well a.s between such opposite sides. The supply conduits inclucle an elongate manifold conduit extencling transversely of the housing, a pair of substa.ntially semi-circular conduit fittings for connecting opposite ends of the manifold conduit with the opposite sides of the housing, respectively, a.nd at least one conduit for connecting the manifold conduit intermediate its ends with the housing between the opposite sides thereof. The die conduits prefer-ably extend in cantilever fashion from individual headers which are clamped together in the a.ssembled apparatus, so one or more of the die conduits can be ea.sily replaced with other die conduits of different shape or sha.pes. One or more plug means for changing materia.l flow capacity : ~:
of selected conduit sections is preferably provided. ~ .

DET~IL,ED DESCRIPTION OF IL,LUSTRATED EMBODIMENTS
.. ....
In the form illustrated in Figs. 1-9, the apparatus of the 15 invention comprises a compound die 10 of broaclly rectangular configura-tior. thro~lgh which respective components oE the final product are differentially extrudecl. Since naturally formed and processed bacon slabs are made up of random striations of fat and lean pork as they occur in pork bellies, the materials fed to die 10 in the pr~sent instance are 20 rninced lean pork trimmings and fat pork trimmings, respectively, and the apparatus includes means for continuously feeding these materials to respectively different, non-communicating portions 10a and 10b of the die.
The feeding means comprise in this embodiment of the invention twin screw, mixer feeders 11 and 12, respectively, which may be of any 25 suitable type, but are preferably as disclosed and claimed in McFarland U.S. Patent No~ 3, 825,231, granted July 23, 1974, and entitled "lbvin Screw Continuous Processing Machines". Each comprises a hopper, lla and 12a, respectively, and twin screw conveyors, llb and 12b, respectively. The 35~
discharge from mixer feeder 11 leads through conduit 13, food pump 14, riser 15, a.nd cond~it 16 .o the front of die 10 a.nd into individual conduit portions 10a. thereof by wa.y of plenum fitting 17, while discharge from mixer feeder 1~ leads through conduit 1~, food pump 19, riser 20, conduit 21, a.nd heade:r or rnani-fold 22 into rectangular die housing 23 surrounding the die conduits lQa and forming therewith the intercommunicating die . .
passages 10b. Part of such discharge pa.sses through the top wall of die housing 23 by wa.y of nipple members 23a and b thereof and into interior passa.ge portions 10b thereof that surround but a.re not in communication with the passage portions 10a of the die. Other parts of such discharge ,: ~ .
pass out of respectively opposite ends 22a a.nd b of header 22, through substantially semi-circular conduit t`ittings 24 and 25, respectively~ and through respective side wa.lls of die housing 23 by way of nipple members 23c a.nd d thereof, respectively, a.nd into the same interior passage portions lUb thereof into which nipple members 23a. and b discharge, but a.t opposite ends of such passage portions 10b so as to insure complete filling thereof with the material to be extruded therethrough and there-from.
Portions 10a of die 10 are rigidly secured in front wall 23e of die housing 23 and extend bacl~wardly in cantilever fashion through the :~;
interior of such die housing to terminate in a common area at the open rear of the hcusing which forms discha.rge orifice 10c, Figs. 3 and Ds, of ;:
the die. Non-communicating die passages 10a and 10~ of the die ha.ve discharges in common at die discharge orifice 10c, so that the discharged extrusion product is a continuous column of the different materials from hoppers lla and 12a interleaved as random striations.
Means are provided at the common discharge area of die 10 for applying consolidating pressure to the extruded column that emerges 3~
from die 10 through discha.rge orifice 10c. In this illustrated instance, a convergent conduit 26 having substa.ntially the cross-sectiona.l shape of the extruded column is provided as a continua.tion of die 10, so the ..
extruded column is compressed as the extrusion process continues within a.nd through conduit 26. The final extrusion emerges through a discharge `
plate 27, which is provided in this insta.nce as a. cover for the recessed discharge end 26a, see Figso 3 and 4, of conduit 26 to accommodate a cut-off knife (not shown) if desired -for ma.king either slab or strip cuts a.s desired. Discha:rge of ba.con strips, slabs, or of a continuous column for la.ter cutting, is preferably directly onto a belt conveyor 28, Fig. 1.
It is desirable, and a feature of the invention advantageously included in a.ll instances, tha.t the operation be carried out under conditions of deaereation of the feed ma.teria.l, whereby voids a.re prevented in the final product. To this end, pumps 14 a.nd 19 are constructed to substan-tially eliminate a.ir from the feed material that is pa.ssed from hoppers lla. a.nd 12a. to extrusion die 10. Such pumps are preferably oî rota.ry, vane type, e.g., simila.r to that shown by UOS. Patent No. 2,968,253 of January 17, 1971. For deaeration purpOSeS, pipes or hoses 14a and 19a are passed through the face pla.tes of the respective pumps to pressure areas adjacent 20 the respective axes of such pumps and extend to discharge above or within the respective feed hoppers lla and 12a so tha.t any solid material discharged -with the air or other ga.s will be recycled.
The several parts of the apparatus above-described are preferably made a.s separate pieces, as shown in Fig. 4, a.nd removably 25 secured together by bolts, screws, cla.mps, or the like with interposed ga.skets, as indicated, to prevent leaka.ge and to permit easy clea.ning after use~
In Figo 6 is shown a. varia.tion of the bacon striation pattern for -6- :
the die.
In Figs. 7 and 8 is shown still a.nother variation of the bacon striation, the consolidated extrusion product therefrom being shown in Fig. 9 with the interleaved materials designated 29 a.nd 30, respectively.
For consolidation purposes, suitable binders such as mineral salts which chemically affect superficial surfa.ces of meat to provide protein adhesive coatings thereon, may be introduced with the meat .
materials, and the resulting composite extrusions may be exposed to microwaves for protein coagulation prior to case hardening and tempering ` . :. -in the usua.l manner to facilitate slicing. ..
Die configuration can, of course, be varied and die construction will be as required for pa.rticula.r types of proclucts, the illustrated embocliment being suitable for the type of interleaving that produces stria.tions resembling bacon. For other products, it may be desirable to have more than two different materials a.nd it rnay be desirable to have :regula:r stria.tions or laminations, rather than the random ones found desirable to simulate baco~l.
In producing simulated bacon by the extrusion process previou~ly:
described, it is not necessary to use pork as the feed meat materials.
Other meats and/or vegetable materials, such as bee:f, lamb, goat, sea foods, poultry, meat substitutes of vegetable origin, cereals, etc. may be extruded through the same die arrangement. Also7 as previously indicated, the extrusion die arrangement may be such a.s to produce a variety of simulated shapes and cuts other than bacon.
~5 A somewhat later embodiment of the appa.ratus of the invention as specifically employed for the production of simulated ba.con slabs is now preferred and is illustra.ted in Fig. 10 in exploded form corresponding to the showing of the original embodiment in Fig. 4.
3~
~,.
In this form of the invention, individual die conduits, as a.t . -~
31 and 32, or individual conduit die sets, a.s at 33a. and 33b, extend in cantilever fashion from respective hea.ders, 34, 35, and 36, which are adapted to be clamped together as a single unit by mea.ns of a cla.mp- ;~
5 ing device, 37.
For stability during use and for ea.se of assembly, die conduit hea.ders 34 a.nd 35 are grooved a.s at 34a a.nd 35a, respectively, a.nd die conduit header 36 is grooved as at 36a and 36b for ma.ting with the grooves 34a and 35a.. A1SOJ clamping device 37 is providec~ with ~ ;
10 upper and lower cha.nnels 37a and 37b, respectively, for ~he insetting thereinto oE tlle assembled die conduit headers 34, 35, and 36 prior to cla.rnping them into place by means of cla.mping screws 37c and 37d .
and cla.mping nuts 37b a.nd 37f.
As so assembled a.nd cla.mped together a.s a unit, the die 15 concluit hea.ders are properly aligned with respective extrllsion entry openings 38, 39, 40a a.nd 40b of front wall 41 of die housing 42 by ~ ~
sets of pins 43 projecting from the respective hea.ders for reception ~ ~:
by correspondingly placed holes 4a~ in die housing front wall 41 and by correspondingly placed holes 45 in securement flange 46a of plenum 20 fi~ting 46.
It should be noted that ~ront wall 41 of die housing 42 is provided with continuous peripheral grooves, a.s a.t 47, surrounding extrusion entry openings 38, 39, 40a., and 40b for the reception of O-ring type of gaskets 48 and 49, respectively, and that pins 43 -~5 proJect ba.ckwardly from front wall 34, as a.t 43a, for reception by correspondingly placed openings S0 in a. securement flange 42a of die housing 42 a.nd by correspondingly placed holes 51 in a gasket 52 which is interposed between the clamped die conduit hea.ders and such ~.
:Ela.nge 42a of the die conduit housing.
It has been -found unnecessa.ry to rnake the die conduits as long as indicated -for the previously described embodiment of Fig. 4.
Consequently, die housing 42 is shorter from front to back than is die 5 housing 23 of the first embodiment. As in the first embodiment, the die conduits of the present embodiment extend entirely through die housing 42 and termina.te at a rea.r securement flange 42b of die housing 42. A
convergent discharge conduit (not shown) corresponding to the discharge conduit 26 of the first embodiment, is removably attached to die ~onduit 10 housing 42, preferably by a second clamping device 53 engaging secure-ment flange 42b of die housing 42 and a. similar securement flange (not shown) on the discha.rge conduit along with a.n interposed gasket 54.
~ feed material simulating the lean rneat component of a ba.con slab is fed under pressure and deaeration into plenum fitting 46 for extrusion through entry openings 38, 39, and 40a a.nd 40b of front plate ~-41 into a.ncl through die concluits 31, 32, and 33a a.nd 33b, respectively, in the manner a.nd by the means previously described with respect to the first embodiment.
~ s in ~he first embodiment, a food material simulating the fa~
20 component of a. ba.con slab is simila.rly fed under pressure a.nd deaeration to the die passages surrounding the die conduits in the housing 42 when the apparatus is assembled for use. Thus, such fat-sirnulating food ma.terial is fed in~o elongate header or manifold 55 which extends trans-versely of the die conduits and the die housing in the a.ssembled form of 25 the a!~pa.ratus similar to the showing in Figs. 2 and 3. Semi-circular conduit fittings 56 and 57 are adapted to removably connect opposite ends ~: -55a and 55b of manifold 55 with nipple members 42c and 42d, respectively at opposite la.teral sides of die housing 42, thereby projecting the feed :
material through the die passa.ges that are interleaved with the d;e conduits.
Part of the feed ma.terial will, a.s in the first embodiment, be projected into the interior of the die housing through a wall thereof that extends between the opposite latera.l sides of such die housing. Here, only one nipple member 42e is provided in the upper wa.ll of die housing a~2 for connection with a. single nipple member 55c depending from manifold 55. The feed ma.terial is introduced into nipple member 55d of manifold 55 as described for the first embodirllent with respect tO feed conduit 21 thereof.
It ha~s been .~ound adva.ntageous to control the qua.ntity of feed through one or more of the nipple members 55d, 55a, and 55b by means Oe respective insertable a.nd removable plugs 58" Figs. 11 and 12, which have a. substantia.lly semi-circula.r base 58a a.ncl which are tapered a.long their lerlgths therefrom to a.n apex S8. Ea.ch pll~g is supported by a. pla.te member 59 provided, as by welding, at the ba.se and partially across ~he opening of a nipple member in its joinder to the die housing 42. To keep the plug from turning or rota.ting in its nipple member when installed, a boss 58c is provided at and projecting longitudinally from the forward portion of ba.se 58a. for engagement with the forward margin of the corresponding plate member 59.
The base of a plug 58 may be more or less than semi-circular as circums~:ances may warrant in any pa.rticular use of the apparatus, and, in each instance, the supporting plate 59 will be similarly dimen-sioned to receive the protruding boss 58c of the plug. :
It should be rea.li2ed tha.t one or more of the plugs, or none, ma.y be employed in any given instance of use of the appa.rat~ls as may be deemed necessa.ry or desirable by the operator.
Whe:reas this invention is here illustra.ted a.nd described with specific reference to an embodiment thereof presently contempla.ted as `
the best mode of carrying out such inven~ion in actua.l practice, it is to be - ~ .
understood that various changes may be made in adapting the invention to ~ "

State of the Art Loa.ves and other shapes of meat materials have long been prepared by ma.nually arranging different meat pieces together9 with or witho~t binders, and by consolidating such pieces under pressure to form a product which is commercially attractive and can be 10 sliced. Some attempts have been ma.de heretofore to simulate cuts of meat, such as bacon slabs by this technique. Also, ground or emulsified mea.t a.nd fat mixtures have been extruded and cut to simulate known commercia.l cuts. Various types of app~ratus ha.ve been developed here-tofore for extruding different ma.terials, such as soap of differen~ colors, 15 and consolidating the different ma.terials as a final unitary productO .
Objective: The present invention has a.s its primary objective to eliminate time consuming a.nd expensive ma.nua.l fabrication of commer- .
cially a.ccepta.ble meat shapes having desirable striation of different meat ormeatandfatcha.racteristics, especiallysimulatedbaconslabs, by 20 apparatus that effectively accomplishes the purpose and can be quickly a.nd easily disassem~led for cleaning and rea.ssembled for further use~
BRIEF SUMM~RY OF T~IE INVENTION
In accomplishing the objective of the invention, ingredients for the respective striations are fed to and extruded through different portions 25 of a compound die. The respective extrusions are interleaved as they emerge from the different portions of the die into a common discharge area thereof, where they a.re comp:ressed into a coherent column and discha.rgecl as a continuous colurnn. The column may have a.ny desired shape, a.s, For exa.mple~ a slab, and is cut tra.nsversely in desired lengths to :Eorm the fina.l product, e g., ba.con slabs.
Suitable binders, for e~ample, mineral salts that chemically 5 affect superficial surfaces of meat to provide protein adhesive coatings thereon, are usually included with meat pieces or fragments fed to the die, thereby firmly binding such pieces or fragments together under the pressures encountered cluring extrusion. :~
The opera.tion is a.dva.ntageously carried out under conditions 10 of deaera.tion of the feed materials, thereby insuring against the occurrence of undesira.ble voids in the resulting product.
When the product is ba.con, the die may be configurated to pro-duce striations of random thicknesses and positions closely simulating those of natura.l bacon. The extruded column rna.y be cooled preparatory 15 to the imr~lediate slicing of bacon strips from the column, or the extruded column may be exposed to microwaves -Eor prot:ein coagulation a.nd then case hardened and tempered in the usual :manner for slicing.
The apparatus includes an extrusion assembly comprising a die ha.ving a housing within which extend a plurality of individual die conduits 20 from a. front wa.ll provided with openings lea.ding into the die conduits. The space surrounding the die conduits within the housing form die passages interleaved with the die conduits. Means are provided for extruding a food material through the front wall openings and through the die conduits into a convergent discharge conduit removably a.ttached to the housing. Separ-25 able supply conduits connect a pressure source of supply of a differentfood material with the housing at opposite sides thereof as well a.s between such opposite sides. The supply conduits inclucle an elongate manifold conduit extencling transversely of the housing, a pair of substa.ntially semi-circular conduit fittings for connecting opposite ends of the manifold conduit with the opposite sides of the housing, respectively, a.nd at least one conduit for connecting the manifold conduit intermediate its ends with the housing between the opposite sides thereof. The die conduits prefer-ably extend in cantilever fashion from individual headers which are clamped together in the a.ssembled apparatus, so one or more of the die conduits can be ea.sily replaced with other die conduits of different shape or sha.pes. One or more plug means for changing materia.l flow capacity : ~:
of selected conduit sections is preferably provided. ~ .

DET~IL,ED DESCRIPTION OF IL,LUSTRATED EMBODIMENTS
.. ....
In the form illustrated in Figs. 1-9, the apparatus of the 15 invention comprises a compound die 10 of broaclly rectangular configura-tior. thro~lgh which respective components oE the final product are differentially extrudecl. Since naturally formed and processed bacon slabs are made up of random striations of fat and lean pork as they occur in pork bellies, the materials fed to die 10 in the pr~sent instance are 20 rninced lean pork trimmings and fat pork trimmings, respectively, and the apparatus includes means for continuously feeding these materials to respectively different, non-communicating portions 10a and 10b of the die.
The feeding means comprise in this embodiment of the invention twin screw, mixer feeders 11 and 12, respectively, which may be of any 25 suitable type, but are preferably as disclosed and claimed in McFarland U.S. Patent No~ 3, 825,231, granted July 23, 1974, and entitled "lbvin Screw Continuous Processing Machines". Each comprises a hopper, lla and 12a, respectively, and twin screw conveyors, llb and 12b, respectively. The 35~
discharge from mixer feeder 11 leads through conduit 13, food pump 14, riser 15, a.nd cond~it 16 .o the front of die 10 a.nd into individual conduit portions 10a. thereof by wa.y of plenum fitting 17, while discharge from mixer feeder 1~ leads through conduit 1~, food pump 19, riser 20, conduit 21, a.nd heade:r or rnani-fold 22 into rectangular die housing 23 surrounding the die conduits lQa and forming therewith the intercommunicating die . .
passages 10b. Part of such discharge pa.sses through the top wall of die housing 23 by wa.y of nipple members 23a and b thereof and into interior passa.ge portions 10b thereof that surround but a.re not in communication with the passage portions 10a of the die. Other parts of such discharge ,: ~ .
pass out of respectively opposite ends 22a a.nd b of header 22, through substantially semi-circular conduit t`ittings 24 and 25, respectively~ and through respective side wa.lls of die housing 23 by way of nipple members 23c a.nd d thereof, respectively, a.nd into the same interior passage portions lUb thereof into which nipple members 23a. and b discharge, but a.t opposite ends of such passage portions 10b so as to insure complete filling thereof with the material to be extruded therethrough and there-from.
Portions 10a of die 10 are rigidly secured in front wall 23e of die housing 23 and extend bacl~wardly in cantilever fashion through the :~;
interior of such die housing to terminate in a common area at the open rear of the hcusing which forms discha.rge orifice 10c, Figs. 3 and Ds, of ;:
the die. Non-communicating die passages 10a and 10~ of the die ha.ve discharges in common at die discharge orifice 10c, so that the discharged extrusion product is a continuous column of the different materials from hoppers lla and 12a interleaved as random striations.
Means are provided at the common discharge area of die 10 for applying consolidating pressure to the extruded column that emerges 3~
from die 10 through discha.rge orifice 10c. In this illustrated instance, a convergent conduit 26 having substa.ntially the cross-sectiona.l shape of the extruded column is provided as a continua.tion of die 10, so the ..
extruded column is compressed as the extrusion process continues within a.nd through conduit 26. The final extrusion emerges through a discharge `
plate 27, which is provided in this insta.nce as a. cover for the recessed discharge end 26a, see Figso 3 and 4, of conduit 26 to accommodate a cut-off knife (not shown) if desired -for ma.king either slab or strip cuts a.s desired. Discha:rge of ba.con strips, slabs, or of a continuous column for la.ter cutting, is preferably directly onto a belt conveyor 28, Fig. 1.
It is desirable, and a feature of the invention advantageously included in a.ll instances, tha.t the operation be carried out under conditions of deaereation of the feed ma.teria.l, whereby voids a.re prevented in the final product. To this end, pumps 14 a.nd 19 are constructed to substan-tially eliminate a.ir from the feed material that is pa.ssed from hoppers lla. a.nd 12a. to extrusion die 10. Such pumps are preferably oî rota.ry, vane type, e.g., simila.r to that shown by UOS. Patent No. 2,968,253 of January 17, 1971. For deaeration purpOSeS, pipes or hoses 14a and 19a are passed through the face pla.tes of the respective pumps to pressure areas adjacent 20 the respective axes of such pumps and extend to discharge above or within the respective feed hoppers lla and 12a so tha.t any solid material discharged -with the air or other ga.s will be recycled.
The several parts of the apparatus above-described are preferably made a.s separate pieces, as shown in Fig. 4, a.nd removably 25 secured together by bolts, screws, cla.mps, or the like with interposed ga.skets, as indicated, to prevent leaka.ge and to permit easy clea.ning after use~
In Figo 6 is shown a. varia.tion of the bacon striation pattern for -6- :
the die.
In Figs. 7 and 8 is shown still a.nother variation of the bacon striation, the consolidated extrusion product therefrom being shown in Fig. 9 with the interleaved materials designated 29 a.nd 30, respectively.
For consolidation purposes, suitable binders such as mineral salts which chemically affect superficial surfa.ces of meat to provide protein adhesive coatings thereon, may be introduced with the meat .
materials, and the resulting composite extrusions may be exposed to microwaves for protein coagulation prior to case hardening and tempering ` . :. -in the usua.l manner to facilitate slicing. ..
Die configuration can, of course, be varied and die construction will be as required for pa.rticula.r types of proclucts, the illustrated embocliment being suitable for the type of interleaving that produces stria.tions resembling bacon. For other products, it may be desirable to have more than two different materials a.nd it rnay be desirable to have :regula:r stria.tions or laminations, rather than the random ones found desirable to simulate baco~l.
In producing simulated bacon by the extrusion process previou~ly:
described, it is not necessary to use pork as the feed meat materials.
Other meats and/or vegetable materials, such as bee:f, lamb, goat, sea foods, poultry, meat substitutes of vegetable origin, cereals, etc. may be extruded through the same die arrangement. Also7 as previously indicated, the extrusion die arrangement may be such a.s to produce a variety of simulated shapes and cuts other than bacon.
~5 A somewhat later embodiment of the appa.ratus of the invention as specifically employed for the production of simulated ba.con slabs is now preferred and is illustra.ted in Fig. 10 in exploded form corresponding to the showing of the original embodiment in Fig. 4.

In this form of the invention, individual die conduits, as a.t . -~
31 and 32, or individual conduit die sets, a.s at 33a. and 33b, extend in cantilever fashion from respective hea.ders, 34, 35, and 36, which are adapted to be clamped together as a single unit by mea.ns of a cla.mp- ;~
5 ing device, 37.
For stability during use and for ea.se of assembly, die conduit hea.ders 34 a.nd 35 are grooved a.s at 34a a.nd 35a, respectively, a.nd die conduit header 36 is grooved as at 36a and 36b for ma.ting with the grooves 34a and 35a.. A1SOJ clamping device 37 is providec~ with ~ ;
10 upper and lower cha.nnels 37a and 37b, respectively, for ~he insetting thereinto oE tlle assembled die conduit headers 34, 35, and 36 prior to cla.rnping them into place by means of cla.mping screws 37c and 37d .
and cla.mping nuts 37b a.nd 37f.
As so assembled a.nd cla.mped together a.s a unit, the die 15 concluit hea.ders are properly aligned with respective extrllsion entry openings 38, 39, 40a a.nd 40b of front wall 41 of die housing 42 by ~ ~
sets of pins 43 projecting from the respective hea.ders for reception ~ ~:
by correspondingly placed holes 4a~ in die housing front wall 41 and by correspondingly placed holes 45 in securement flange 46a of plenum 20 fi~ting 46.
It should be noted that ~ront wall 41 of die housing 42 is provided with continuous peripheral grooves, a.s a.t 47, surrounding extrusion entry openings 38, 39, 40a., and 40b for the reception of O-ring type of gaskets 48 and 49, respectively, and that pins 43 -~5 proJect ba.ckwardly from front wall 34, as a.t 43a, for reception by correspondingly placed openings S0 in a. securement flange 42a of die housing 42 a.nd by correspondingly placed holes 51 in a gasket 52 which is interposed between the clamped die conduit hea.ders and such ~.
:Ela.nge 42a of the die conduit housing.
It has been -found unnecessa.ry to rnake the die conduits as long as indicated -for the previously described embodiment of Fig. 4.
Consequently, die housing 42 is shorter from front to back than is die 5 housing 23 of the first embodiment. As in the first embodiment, the die conduits of the present embodiment extend entirely through die housing 42 and termina.te at a rea.r securement flange 42b of die housing 42. A
convergent discharge conduit (not shown) corresponding to the discharge conduit 26 of the first embodiment, is removably attached to die ~onduit 10 housing 42, preferably by a second clamping device 53 engaging secure-ment flange 42b of die housing 42 and a. similar securement flange (not shown) on the discha.rge conduit along with a.n interposed gasket 54.
~ feed material simulating the lean rneat component of a ba.con slab is fed under pressure and deaeration into plenum fitting 46 for extrusion through entry openings 38, 39, and 40a a.nd 40b of front plate ~-41 into a.ncl through die concluits 31, 32, and 33a a.nd 33b, respectively, in the manner a.nd by the means previously described with respect to the first embodiment.
~ s in ~he first embodiment, a food material simulating the fa~
20 component of a. ba.con slab is simila.rly fed under pressure a.nd deaeration to the die passages surrounding the die conduits in the housing 42 when the apparatus is assembled for use. Thus, such fat-sirnulating food ma.terial is fed in~o elongate header or manifold 55 which extends trans-versely of the die conduits and the die housing in the a.ssembled form of 25 the a!~pa.ratus similar to the showing in Figs. 2 and 3. Semi-circular conduit fittings 56 and 57 are adapted to removably connect opposite ends ~: -55a and 55b of manifold 55 with nipple members 42c and 42d, respectively at opposite la.teral sides of die housing 42, thereby projecting the feed :
material through the die passa.ges that are interleaved with the d;e conduits.
Part of the feed ma.terial will, a.s in the first embodiment, be projected into the interior of the die housing through a wall thereof that extends between the opposite latera.l sides of such die housing. Here, only one nipple member 42e is provided in the upper wa.ll of die housing a~2 for connection with a. single nipple member 55c depending from manifold 55. The feed ma.terial is introduced into nipple member 55d of manifold 55 as described for the first embodirllent with respect tO feed conduit 21 thereof.
It ha~s been .~ound adva.ntageous to control the qua.ntity of feed through one or more of the nipple members 55d, 55a, and 55b by means Oe respective insertable a.nd removable plugs 58" Figs. 11 and 12, which have a. substantia.lly semi-circula.r base 58a a.ncl which are tapered a.long their lerlgths therefrom to a.n apex S8. Ea.ch pll~g is supported by a. pla.te member 59 provided, as by welding, at the ba.se and partially across ~he opening of a nipple member in its joinder to the die housing 42. To keep the plug from turning or rota.ting in its nipple member when installed, a boss 58c is provided at and projecting longitudinally from the forward portion of ba.se 58a. for engagement with the forward margin of the corresponding plate member 59.
The base of a plug 58 may be more or less than semi-circular as circums~:ances may warrant in any pa.rticular use of the apparatus, and, in each instance, the supporting plate 59 will be similarly dimen-sioned to receive the protruding boss 58c of the plug. :
It should be rea.li2ed tha.t one or more of the plugs, or none, ma.y be employed in any given instance of use of the appa.rat~ls as may be deemed necessa.ry or desirable by the operator.
