Description

Mold for forming meat masses intended for be sliced, particularly seasoned sausages.

The present invention relates to a mold for form meat masses intended to be sliced, in particular seasoned sausages, in a substantially regular manner.

Then, for convenience, reference will be made only seasoned and peeled ham, it being understood that how much it will be said it will also be valid for other meats, for example the "speck" that is cooked ham, defined below simply as a product or meat dough.

To conform the product, they are known facilities by means of which it can be conferred to the product a very regular, typically parallelepipedic basis straight, meaning that it has a constant straight section suitable for slice the product.

The known installations comprise a mold composed of a parallelepiped forming matrix that has at least two movable walls, of which one is a buffer top or cover and a retaining wall suitable for moving according to the longitudinal axis of the matrix in the cavity defined by the matrix and by the lid.

At the end of the cavity, opposite to said retaining wall, a fixed transverse wall is arranged removable.

The elements that define the mentioned cavity are properly cooled.

An installation of the type described is illustrated in Italian patent 1239207 in the name of the same applicant, and it allows to obtain a parallelepipedic mass of meat; to guarantee that the dough retains its shape, the shaped dough should be put in a second mold consisting of two complementary semiconchas, the which are enclosed in a vacuum enclosure to ensure its congruence and then preserved in an environment cooled by a Timely time.

The known facilities give the product a parallelepipedic form thanks to which the product can be sliced according to slices that have practically the same dimension, therefore also substantially the same equal weight of thickness.

Product slicing is done with machines high productivity automatic in which the end of the product is caught by a clamp coupled to a feed system Automatic and adjustable.

Said clamp nevertheless prevents the product is sliced completely, and causes a waste that involves a economic loss too high given the cost of the product.

Therefore, in the specific sector you feel deeply the demand for suitable means to reduce the presence of waste

The main objective of the present invention is now to meet that requirement in the context of a solution constructive simple, rational, economical, reliable and durable.

A further objective is to prevent the second Mold must be made congruent in an envelope under vacuum.

Another objective is still to make available a mold of forming that avoids the use of the second mold.

These objectives are achieved, according to the invention, thanks to a mold suitable for creating in the product a protruding terminal appendage having a cross section less than the straight section of the product, and a length such that can be picked up by the slicer tongs.

In this way the waste is practically reduced to only the appendix, with obvious advantages in appearance economic.

Said appendix may take various forms, for square or rectangular example and will have compatible dimensions with the usual automatic slicer tongs.

The means provided for the creation of said appendix understand, as will be specified in detail to then a cavity that is practiced on the surface active of one of the transversal organs that delimit the aforementioned mold forming cavity, preferably on said wall transversal containment.

Preferably said transverse wall of containment is interchangeable with one of a series of walls that they have cavities compatible with the slicers of slicing machines specific.

The invention subsequently provides a mold that, once closed, it presents a stable congruence even when it is separate from the installation, and is therefore suitable to be put in a refrigerated environment together with the product contained in the same.

Said mold is therefore suitable for both constitute the second mold of the installation, destined to preserve the shape of the product, as the only mold intended for both conform the product as to preserve its shape through permanence in refrigerated environment.

Fig. 16 is section XVI-XVI indicated in Fig. 15.

From the set of Figs. 1 to 6, highlights a mold simple fixed forming, which obviously can be incorporated in a more complex installation or machine as will be represented by example in Fig. 7.

The machine 100 of Fig. 7 comprises three molds according to the solution of Figs. 1 to 6, but it is clear that That number may also vary.

Naturally the same machine 100 can incorporate molds according to alternative solutions according to the other figures 7 to 9.

The forming mold (Figs. 1 to 6) comprises a fixed matrix 1 of containment of meat 99 to be formed, a first removable fixed wall 2, a second transverse wall 3 of containment that is opposite to the previous one and that is apt to slide with respect to it according to an approach movement and remoteness, and a cover 4 of vertically mobile pressing which is suitable for closing the cavity 5 of forming the matrix 1.

Cavity 5 is elongated, and is arranged horizontally, and has a constant cross section (Figs. 4 and 6).

Product 99 is introduced into cavity 5 with the fibers arranged according to the latter's generatrices.

The first retaining wall 2, which is fixed during operation, it is put to the head at one end of the matrix 1, has dimensions greater than those of the straight section of the cavity 5, and is placed under the control of a double jack 20 effect arranged above.

Also stage 4 is rigid, has a length and a width that are equal to those of cavity 5, and is set under the control of a double-acting cat 40 arranged above.

The second retaining wall 3, received at sliding form inside cavity 5, and put under control of a respective double-acting cat 30, and is elastically yielding low the upper buffer thrust 4.

In particular, see Fig. 1, in configuration The wall 3 has a lower height than the depth of the cavity 5.

It comprises a lower base 6 formed in the form of a channel within which it is telescopically received, with interposition of suitable elastic means, a plate 7 which is subsequently equipped with two grooves 31 with which they are respective couplings 32 guide and sliding bolts (see Fig. 3).

The base 6 is hooked to the stem of the cat 30 by means of a system 33 of prismatic coupling.

In the case shown, plate 7 is supported. by cylindrical springs 34 that are engaged in the bottom of said base 6 by means of screw flanges.

In addition, see Figs. 1, 2 and 5, the section transverse of the channel of said base 6 is inclined towards the face previous or active of it.

This prevents that, during the phase of formed, between the base 6, the plate 7 and the buffer 5 form a cavity where a part of meat that would be crushed would be inserted by buffer 5 inconveniently.

In addition, according to the invention, on the front face of the base 6 is provided a recess or cavity 66.

It is ready to create, in the corresponding end of the 99 formed meat dough, a projection or appendix 77 of meat that is intended to be caught for the feeding devices of the slicers automatic

In the case represented, said cavity 66 is of rectangular shape (see Fig. 6) but it can take any another form, for example the square form.

The dimensions of that appendix may vary. depending on the type of meat and / or slicing machine.

According to an advantageous feature of the invention the installation may be provided with a series of walls 3 having cavities 66 sized in shape diverse.

It is required that the mold parts are equipped of suitable ducts 55 or interlayers for the passage of a liquid refrigerant suitable for keeping processed meat at a adequate temperature

The mold of figures 1 to 6 works as follow.

After loading the mass 99 into the cavity 1, the mold is closed as illustrated in Fig. 2, with the wall 3 leading to the position represented in slight delay with respect to the decrease in buffer 4.

The decrease in buffer 4 causes a slight deformation of mass 99 before it finds support against plate 7, which descends against resistance offered by the docks 34.

Then buffer 4 stops before reaching its own end of descent race, after which wall 3 move forward and push the dough against wall 2 until you find a preset resistance, detected by a suitable organ (not represented), as an adjustable pressure transducer. In this point wall 3 stops, and buffer 4 receives permission to effect small reciprocating movements that develop on horseback the position previously reached.

This without losing contact with plate 7 and without Reach your own end of descent race.

In this way the meat dough 99 is subjected to a Delicate massage that allows the same meat fibers 99 spread substantially naturally, bringing said mass to take the shape of the hole defined by elements 1, 2, 3 and 4.

\hbox{hueso.}

Furthermore, said delicate massage allows the meat to be deaerated completely, in particular in correspondence with the area from which the meat has been extracted.

 \ hbox {bone.} 

Timing means are provided for selection of the duration of said massage based on the characteristics of processed meat, and during the cycle of shaped mold is conveniently cooled.

\hbox{tampón 4.}

At the end of said massage, the buffer 4 is brought to its own downward stroke end (see Fig. 5), where the upper face of the plate 7 is practically butt against the upper face of the body with channel 6, the face lower of the same plate 7 is separated from the bottom of said body 6, and the upper face of the latter is slightly separated from the

 \ hbox {buffer 4.} 

In addition, also the retaining wall 3 can be submitted, for a convenient period adjustable at discretion, to a small reciprocating movement when buffer 4 is completely lowered.

This is intended to ensure that the meat it takes exactly the shape of cavity 5, particularly that in the end of mass 99 the forming of said appendix is completed 77.

At the end of forming the mold is closed for a period sufficient to eliminate all heat. generated in the meat for such compressions and massages.

Then, wall 2 rises, and wall 3 advances to unload the mass 99, which is placed in a second mold, the which fits its shape, which is placed in a low envelope empty to ensure congruence.

Said second mold is then arranged by a certain time in a refrigeration cell.

According to the embodiment of Fig. 8 a end (the one on the left) of cavity 5 is closed by a fixed wall 222 integral with matrix 1, and the discharge of mass 99 of meat is made by a plate 333 bottom extractor put under the control of a 444 double acting cat.

According to the solution of Fig. 9 the kneading of the meat is due to the action of retaining wall 106, which, after lowering buffer 4 until the end of the descent race, where he finds support against mass 99, he moves forward and is subjected to a slight swaying movement.

Also in this case the installation may be provided with a series of walls 106 that have cavities sized differently.

In each case, at the end of forming the mass 99 It is presented as shown in Fig. 10, where it stands out the marked difference between scrap the sliced end individualized by central appendix 77 and individualized by the terminal slice 900 marked in dotted lines that is obtained according to the known technique.

Figures 11 to 16, see in particular Fig. 11, illustrate a second embodiment of the mold, which is suitable both to develop the functions of the mold illustrated in Figures 1 to 9, as to develop the functions of the second mold.

For this purpose the mold according to this further form of realization can be directly sent to the refrigeration cell no need for an envelope under vacuum, its congruence being mechanically guaranteed also when separated from respective drive tools.

The mold represented in the cited figures, indicated as a whole with 233, it comprises three elements main components 201, 202 and 203 that will also be defined as matrix, retaining wall and top cap or buffer, respectively.

Said elements 201, 202 and 203 are consisting of a suitable material, for example stainless steel or food type plastic.

Matrix 201 is shaped as a channel closed and has an end like a box that on the previous wall It has a cavity 204 that is shaped like Appendix 244 (see Figs. 2, 3 and 6) to be done in mass 205 of meat.

Appendix 244 is in the form of a rib with straight cross section whose length is arranged according to the major axis of said rectangular cross section of the mass 205.

It is required that the upper mouth of the matrix 201 It is perfectly flat.

According to the invention, on the face external of each side wall of the matrix 201 a pair is provided of pivots 206 that are arranged at the same distance from the edge top of the wall itself.

In addition, each of said side walls presents, on the part of the open end of the matrix 201, a longitudinal series of holes 207 through through crossings and regularly separated.

Holes 207 of said two series are coaxial two to two and to them a pin 277 is associated.

The retaining wall 202 consists of a plate whose shape coincides with that of the anterior wall of the matrix 201.

The upper buffer or lid 203 is shaped as an inverted channel whose length is equal to that of the matrix 201, and whose flanks are suitable to be arranged outside the side walls of the matrix, practically in contact with the external faces of said side walls (see Fig. 16).

Inside these flanks are individualize two 288 pointed profiles throughout the development and which in section have, on the outside, a flat face parallel to the respective flank of the upper buffer or lid, and inside a arched shape

To these profiles 288 correspond, in the opposite ends of the upper edge of the anterior wall of the matrix 201, two identically shaped recesses 208 (see Fig. eleven).

Finally, each of said tampon flanks top or cover 203 has a pair of shaped cutouts 209 in elongated and broken type that are suitable for coupling with the respective pairs of pivots 206.

Said recesses 209 have a width constant, suitable for receiving pivots 206.

Each notch 209 has two straight sections, of which, one, located below, leading to the edge lower of the respective flank and is inclined towards the end matrix 201 open, and the other one, located above, which is located on the continuation of the previous one and is parallel to the axis of the matrix 201.

In particular, the recesses 209 are positioned and sized so that when its sections horizontal are coupled with pivots 206 the upper buffer or cover 203 is exactly above the matrix 201 (Fig. 5) and press against the upper face of the meat dough 205.

To tighten mold 233 around the dough 205 you can proceed as stated above with reference to Figs. 12 to 16.

An installation comprising a plane is used horizontal operation 210, for example in the form of a tape step conveyor to which at least the two operating groups indicated with 255 and 266.

Frontal to these groups is a stop 211 against which the blind end is destined to find support of matrix 201.

Once matrix 201 has been positioned between the stop 211 and the group 255, the mass is adapted therein 205.

After this the wall of containment 202 as depicted in Fig. 13, and the feed of pusher 250 whose active face is provided with a horizontal groove 251 located at the height of the holes 207. The pneumatic jack 252 is set at a pressure suitable for adapt the mass 205 to the die of the die 201.

At this point pin 277 is inserted into the first pair of free coaxial holes 207 located behind the retaining wall 202, and then pusher 250 goes back and the wall 202 rests on the pin.

Matrix 201 is then transferred to in front of group 266 and on it the buffer is positioned top or cover 203 being careful to attach the ends openings of the recesses 209 with the pivots 206 (Fig. 14).

In this configuration, the pusher 260 until pivots 206 reach the sections horizontal of the recesses 209 (Fig. 15).

\hbox{(Fig. 6).}

Of course, during the sliding of the pivots 206 along the inclined sections of the recesses 209 the upper buffer or lid descends compacting the mass 205, which takes practically the same shape of the closed mold hole 233

 \ hbox {(Fig. 6).} 

Made this the mold-dough set of meat 233-205 is put in a cell refrigerating

The mold according to the invention is suitable also for forms provided with terminal appendix 244.

To this end the mold 233 is provided with a rod 311 of occlusion of cavity 204 of matrix 201, represented in thin lines and dotted lines in Fig. 11. They will be obviously provided adequate means to lock in position the rod 311, for example two head screws (no represented).
