Description

The The invention relates to a process for industrial packaging, to Durable and surface treatment of food, in particular sausage meat, using a foil-like, elastic properties having plastic material, wherein the food, also as a semi-finished product, of the plastic material wrapped and sealed.

From the DE 39 08 585 C2 an elastic wrapper for forming meat is previously known. According to the local object, it is necessary to convert the meat in the packaged state in a circular shape, wherein the envelope is a permanently elastic tube or bag, which lays firmly on the meat by contracting in cross section. The tube or bag may consist of two superimposed film strips, which are welded together at their longitudinal edges. In addition there is according to DE 39 08 585 C2 the possibility that the air or the bag after filling the meat is removed from the tube or bag. Shaping supporting a conical part is provided, wherein the hose or bag is at least partially located on this additional part, which is in communication with the meat supply device.

In the method of packaging objects and / or objects in a packaging device according to EP 0 836 998 B1 is again assumed that an elastic packaging material, which is introduced into a container in which an atmospheric negative pressure is generated, in such a way that the packaging material is stretched in the container by the existing, acting on the packaging material external air pressure, so that a cavity arises, are placed in the one or more items to be packaged in the stretched packaging material. After the negative pressure is released, the elastic packaging material is with the result that this at least partially applies to the packaged object. Furthermore, the packaging material Ver is continuously supplied as a film web or as a film tube and it is formed a device which is able to seal the packaging material.

adversely In this doctrine, that is fundamentally more atmospheric Negative pressure must be generated to the desired To create cavity for receiving the objects to be packaged.

From the DE 198 07 794 C2 is a method for producing and shaping of food, such as meat and sausage products, previously known, where a semi-finished product is placed in a bag or between films, the semi-finished product is vacuum-treated and sealed, the filled packing between two plates adjusted and applied a slight pressure on the pack an even distribution of the contents of the package.

According to the local solution will be the filled pack between two deep-drawing plates of a high and / or deep drawing machine spent, with in accordance with existing Ausmuldungen in the Deep drawing plates a permanent deformation occurs. This lasting Deformation of the filling material is conditioned by a vacuum between thermoforming plates and packing is generated and the Packungswandungen thereby to the shape investing the spoils. Here, the film is stretched and on pressed the existing wells. At the same time the meat is by further reducing the plate spacing completely in crowded the hollows, So that the non-formed foils are flat on one another. The plan superimposed Slide areas can then which are also defined by form-supporting gates Pack sizes can be specified are.

The Although the procedure described above is suitable, the processing steps simplify the packaging and preservation of food, However, it is problematic, the semi-finished product, in particular a sausage, in the sense of a coloring, a defined taste or the Purpose of coating to treat with a layer of another food.

From the U.S. Patent 5,053,239 is a method and an apparatus for the production of packaged in films sausages previously known, with several filling tubes work in parallel or a parallel feed of several intestines or packaging films.

The EP 0 741 973 A1 discloses coextrusion in the production of meat or sausage products for defined layer or cladding formation.

Half shells for stabilizing a foil cover during filling are in the DE 40 20 391 A1 explained.

From the above, it is therefore an object of the invention to provide a further developed process for industrial packaging and for preserving and surface treatment of food, in particular sausage meat, wherein the method to the use of a film-like, elastic Plastic material is reduced and the food, also as a semi-finished product, wrapped by the plastic material and sealed. The process to be specified is concerned with ensuring a continuous, but also discontinuous, quasi-repetitive filling and shaping of, for example, sausages, the filling process basically leading to an air-entrapped product even without negative pressure measures. In addition, it is within the meaning of the invention to design the method so that, alternatively, but also simultaneously a surface treatment within the filling process, ie within a single technological chain, can be realized.

The solution The object of the invention is achieved by a method in his Definition according to the teaching according to claim 1, wherein the dependent claims expedient refinements and developments represent.

According to the invention of an arrangement of a plurality of spaced, preferably in a plane parallel filling tubes same or different cross-section, which fülleingangsseitig with a food feeder communicates.

The Film material becomes continuous on both sides of the filling tube level or fed discontinuously. Subsequently that will be fed Film material consisting of two film webs, one folded Foil or can be formed as an elongated bag, between the filling pipes, this outside circumference tight and tightly enclosing, connected.

In front the first filling process is, if not already present in the embodiment of the film as a bag, executed a transverse seal.

With onset of filling The food, in particular sausage, in the film gap pressed, being over the elastic film material and the control of the relative speed between foil and filling tube outlet a back pressure for air-free Packaging stops.

To the Completion of the respective filling step then, depending from the packaging size and / or the capacity, creates a transverse seal and it starts a new filling step in the next Section of the supplied or further transported plastic film.

To the Receipt of the desired flexibility The film can be heated before and / or during the filling process.

Shaping or supporting can stabilize stabilization the forming film tubes while of the filling process from a rigid, cup-shaped, in particular half-shell-shaped Be surrounded by coat.

This Coat can be filled Foils for execution stabilize the exact transverse seal or even a structuring the film and thus the contents cause.

The Füllrohraustritte the arrangement, consisting of several filling tubes, each have a nozzle, wherein ausgestaltend at the respective Füllrohraustritt this nozzle is designed as injector nozzle, around during of the filling process a uniform application of the food or filling to effect with color, taste or decorative materials.

Here There is in particular the possibility that the filling tubes double-walled or consist of two concentric tubes, which form a gap for feeding have the color, taste or decorative materials.

According to the invention the possibility between the longitudinal and / or transverse sealing sutures Perforation for later Separation in single or group packaging provided.

Farther According to the invention the film inside before filling with the contents with a, preferably heated, Mixture of a treatment substance and carrier material applied, wherein subsequently by cooling the mixture is solidifiable. When later preserving the contents by heat treatment the mixture of treatment substance and carrier material is temporarily in the liquid Condition over and it thereby enters a desired even distribution on the surface of the semi-finished product. Such a surface treatment methodology can even if, for certain technological reasons, the Arrangement of a concentric tube arrangement is not possible or the surface treatment quasi two-stage to be made.

To the application of the heated Mixture of treatment substance and carrier material on the films the temperature is reduced by blowing with cooling air to a desired solidification of the Mixture on the foil surface to effect.

The mentioned above Mixture preferably takes place at room temperature and below a pasty until doughy state and goes on warming in a liquid state of aggregation.

Of the Treatment substance can be a powder or gas that is contained in the product Moisture, which then acts as a kind of carrier material, reacts and a surface layer in the desired way formed.

Of the supplementary The basic idea of the invention is therefore the bag or film inner sides before filling with the semi-finished product, in particular sausage meat, with a preferably heated mixture to apply from a treatment substance and carrier material. This mixture of treating agent and carrier material consists e.g. out Flavoring agents, fragrances and / or decorative substances as well as gelatin, Fats, fat mixtures or the like.

Of the However, treating agent may also be a cheese or cheese-like material, e.g. to obtain a semi-finished product with a layer of cheese as surface cover is provided.

at a supplementary Embodiment, the treatment substance is a powder which, like mentioned above, with the meat residing moisture reacts. Here can be a separate carrier material omitted. The treatment substance may be a powder or smoke powder, which on the meat is applied and that reacts with the moisture of the sausage meat, i.e. first in a mushy-pasty State passes and then optionally liquid becomes.

Here then there is the possibility on one of the foils, e.g. the moving bottom foil, immediately before the foil towards filling tube is spent applying a powder, in particular to scatter. The then filled Roast comes in contact with the powder and it forms a bound within the sausage, optionally coloring, mushy layer made of the sausage meat at the contact or bearing surface purposefully changed.

A possible Heat treatment e.g. along with the step of preserving, allows one repeated change the viscosity of the surface layer with the result that a smoother Wetting or even distribution on the surface of the sausage meat results.

With the solution according to the invention succeeds a significant improvement in industrial packaging for Purpose of preserving food to achieve that is not assumes one with meat filled To divide cushions into individual sausages and subsequently but rather it becomes a matter of principle continuous filling process using known filling tubes applied. According to this, the sausage meat is made single, parallel guided filling tubes in foil tubes pressed, which arise from the fact that the Plastic film webs formed and connected by sealing seams are and in this case at least sections in the longitudinal direction of the filling tubes wrap.

The filling tubes are filling input side with a food feeder connected. The filling pipes can have different cross sections, so that in a single plant different sausage sizes or Packaging units of different contents can be created.

The Respectively the slides above and below the tube level happens in a known Wise. The longitudinal seams will be by pressing on e.g. through heated sealing rolls, sealed webs or with the help of ultrasound devices generated.

As already indicated instead of two film webs also folded films are used, to the effort for reduce the edge seal. Essential is the condition of the Foil, whose extensibility in principle temperature-dependent is. For films that are not already cold enough are elastic, process-wise ensure adequate heating to wear.

at the filling the foil strands must be enclosing the filling tubes be realized by the films so that the ingress of air in the packaging to be created is preventable.

Of the passed through the film Back pressure during filling can be affected by the subsequent heat and cold treatment the packs are still supported become.

at The description of the invention is initially assumed that the Film webs that have been added to the film tubes, during the filling process from the filling outlet side Move away, until the desired packaging or Packing size achieved is.

alternative However, a quasi-repetitive filling process can take place, wherein here the filling pipes against the direction of movement of the film web to a predetermined Move back section, then after completion of the filling executed the transverse seal is, a further transport of the film webs with forward movement the filling tubes in the starting position takes place and in the next step the filling process in the next Track section repeated.
