DE1692585B2 - Method and apparatus for producing a raw poultry meat product consisting of white and dark poultry meat - Google Patents

Description

The invention relates to a method for producing one from white and from dark poultry meat existing raw poultry meat product, in which white and dark pieces of meat are separated with edible Metal salts are mixed in such a concentration and until they are on the surface of the Pieces formed a layer of sal / soluble protein whereupon the pieces of meat in the desired proportions of white and dark meat be extruded into the final product. The invention also relates to a device for performing this Procedure.

Such a method, from which the invention is based, is, for example, from US Pat. No. 3,285,752 remove.

But now a poultry meat product consisting of white and dark poultry meat is then especially appealing when the extruded loaf has a meat part made of white meat and a Meat part is made from dark meat, with the two meat parts different in color are arranged one above the other. In order to come to such a poultry meat product, one has hitherto in arduous and costly work to put the elongated pieces of meat into a container by hand so by selecting the different colored pieces of meat when placing them in the container to a clean one Separation between dark and light meat pieces to come. But it turns out that the end product Shows air pockets or empty spaces and the two end pieces in spite of the most careful handwork in the Poultry dish end product is never aligned accordingly, but were mixed, despite a certain, but not aesthetically pleasing separation made from dark meat and from white meat. The object of the invention is therefore to provide a method to propose, with which it is possible to produce a poultry meat product from cleanly separated Layers of white and dark poultry meat, but the two layers with one another are connected in such a way that they do not differ from one another during the preparation of this raw poultry meat product can separate.

This object is achieved in that the white and dark pieces of meat in two separate layers are extruded and the separation of the layers in the course of the extrusion of is lifted inside and outside.

It is z. B. from US-PS 7 97 276 in the production of ice cream products already known, to feed different ice creams to different extruders and to put the extruder nozzles in a common one To let the mouthpiece open out, so that from this common mouthpiece then a different one Ice cream types of combined ice cream body emerges.

With such a device, however, the problem on which the invention is based cannot be solved. While with ice cream a melting and mixing of the different layers of ice cream occurs and inside at most trapped air because of the prevailing there low temperatures has no effect in terms of separating the various layers, is under the influence of heat for the preparation of a raw poultry meat product consisting of white and off dark poultry, the situation is exactly the opposite. Due to the considerable influence of heat at of the preparation, enclosed air bubbles are expanded so much that the through the salt-soluble protein-induced adhesion in the contact area between white and darker Meat layer dissolves and thus the poultry meat product in two as such no longer meets the requirements corresponding parts disintegrates. The invention ensures that the bonding of the two Different colored meat layers until the poultry meat product is completely released from the mouthpiece the extrusion press progresses from the inside to the outside, thereby the inner bond point inevitably remains longer under the compressive influence of the press mouthpiece and at most existing air bubbles are progressively displaced to the outside and thus during the preparation of the With the poultry meat product, there is no risk of the layers bursting open from the inside due to the action of heat is. Until the poultry meat product is fully cooked, the bond between the two remains in each case Maintained dark and white meat.

A device for carrying out the method according to the invention with mixing and conveying devices for the pieces of meat and with an extruder

b0 whose mouthpiece is the finished raw poultry product emerges in strand form, characterized in that each for the white and for the dark pieces of meat a mixing and conveying device is provided and the extruder devices two of each of the Fördei having fed chambers which are separated from one another by a partition plate, which inside of the press mouthpiece towards the outlet end the same wedge-shaped widening cutout

having.

1 to 4, 10 denotes a container for receiving elongated pieces of poultry meat 11. These pieces of poultry form a seal over a discharge pipe that extends from the lower part of the Container 10 leads to an outer free working space of a fan. In the lower part of the container 10 is a Conveyor shovel arranged for conveying the poultry meat pieces down through the discharge pipe. In addition, one from FIG. 1 vacuum line 16 visible from the area above the blower to a suitable suction source to maintain a vacuum in the area of the blower, which is of any Training can be.

In the embodiment shown in FIGS. 1 to 4, pieces of poultry meat 11 are made of white Meat from the container 10 via a pipe 19 and through the downwardly directed end member 20 into the upper Chamber of an extruder 23, which is provided with a partition plate 21 extending in the longitudinal direction is provided. Dark meat is through the tube 22 led by a similar device with container, blower, etc. to the lower chamber du-extruder 23 leads below the partition plate 21. The extruder 23 has an enlarged central one Area 24 for receiving the pieces of meat and forward-converging side 25, which into the . Extrusion die 26 pass over. The extruder 23 is designed in two parts, the partition plate 21 being arranged in the two chambers. To the Unification of the two chambers are flanges 27 with corresponding threaded holes. To the Screws 28 are used to clamp the two flanges together.

The white meat pieces are conveyed through the pipe 19 into the upper chamber of the extruder 23. In

ίο similarly are the dark pieces of meat introduced through conduit 22 into the lower chamber of extruder 23 under partition plate 21. The two meat piece bodies are combined under pressure and through the mouthpiece 26 on one Endless conveyor 29 or another suitable receiving surface promoted. According to Fig. 1, this consists of the Meat shaped poultry meat product 30 comprising an upper part with white meat and a lower part with dark meat.

In order for the dark layer of meat to stick firmly to the white layer of meat, part of the partition plate is at 21a cut away, as can be seen in FIG. It is the plate part inside the mouthpiece cut out in a wedge shape so that the middle areas of the

2S white and dark pieces of meat brought together and then the contact / .one gradually expands as the unified loaf follows moved forward. This is of particular importance because the middle parts of the dark and light flesh back

ji. ' First loaf together under strong pressure are united and, when the loaf is later ejected, form a firmly held unit so that there is no danger when preparing the light and dark parts in the middle Separate areas of the poultry meat product from each other, so in any case adhesion of the two Types of meat to each other is guaranteed.
