Abstract

The invention concerns a process and a device for processing mixtures of materials in which the mixture is divided into portions of given size, having previously been crushed and/or screened for the subsequent division into portions, and the portions thus produced then further processed in such a way that, when placed together again, they will not adhere to each other and can be fed in the 'detached' state to separating equipment which will separate the mixture into product categories with approximately the same properties.

Description

Method and apparatus for treating substance mixture

The invention relates to a method with an apparatus for treating Stoffge close.

Such procedures and apparatus are necessary to structure such as cohesive in waste, natural products or food mixtures of the ingredients of dissimilar type or different material properties mechanically so that they still mixed, but constituent particles of constituent particles are separated to a further physical and / or chemical separation component type for component type are accessible.

From patent applications EP 0,487,772 Al, a method, for example, is known, is patterned in preparation for the battle material so that it is implemented in the further processing by cutting, pressing or Shredder processes in a mixture of bone, cartilage, tendons, lean meat and fat components becomes.

Also known is an apparatus (see. for example, DE-A-2032774) which bone, cartilage and sinew components on the one hand the other hand, technically and economically more or less satisfactorily separated from the Magerfleisch- and fat components. Also, there are a so-called separation theorem to meat grinders (see FIG. Handbook of Food Technology Prändl / Fischer / Schmidhofer / Sinell, pages 402/403), which consists of suitably prepared battle material bone, cartilage and sinew components removed to some extent and the remaining meat and fat ingredients for further use issues, although it is no longer possible separation of meat and fat.

Also known is an apparatus having a continuously charged with carbon dioxide rotary freezer (see FIG. brochure Buse Gase GmbH u. Co. Cryogen-rapid rotary freezer, Series D), in which infiltrated, in particular water-containing compositions of matter frozen so rapidly that the batch components largely can no longer clump together and are discharged while preserving their original nature and form in bulk. However, this apparatus requires that the components of the plastic mixture are fed already no longer adhered to each other.

In all these known methods and Vorrich¬ obligations difficulty, however, is common to "isolate" the substances to be separated mixture usually intimately mixed and cohesive highly components so that they still mixed available, however, the particles only by a component type are. That is the example of battle material that only substantially pure lean meat particles and fat particles appear individually. This Same problems occur, for example also in the separation of Shreddermüllbes andteilen.

The invention has for its object to provide a novel method and apparatus for the treatment of substance mixtures, in particular for slaughter material to eliminate these difficulties with the least possible effort and without changing the ingredients and enable grouping by approximately the same material properties.

This object is achieved as regards the method by the features of claim 1 and with respect to the apparatus by the features of claim 23rd

Preferred developments of the method result from claims 2 to the 22nd

Preferred further developments of the inventive apparatus according to claim 23 containing the claims 24 to 44.

To realize a device of the invention can in principle a known

Crushing means are used, which, however, must be modified accordingly with respect to the acquisition of portions of a certain size. The selectively comminuted substance mixture in this manner is then divided by a Portionierelementes in portions which are so small that they can be only of a component type in view of the foregoing conditioning substantially. A transfer device then causes these portions are further treated so that they no longer stick together despite .späterem re-merging, and can be supplied via a collection and conveyor unit to the actual separation process which effects the separation of the finally desired single batch components in the further course.'Due to the fact that, for example, provides the portioning element having openings which are formed so that they each take only a predetermined by the previous conditioning of the mixture portion, and can store, it is achieved that substantially either only the one in the corresponding openings or other Gemengebestandteilart occurs. By physical and / or chemical treatment of the portions will be taken to ensure that they can not stick together after re-unification. This is done for example by bringing the portions after removal from the openings of the Portionierelementes with a medium in connection which affects the surfaces of the portions such that no physical and / or chemical binding of the portion is impossible. It is advantageous to use this medium both for the removal of portions of the openings of the Portionierelementes and its collection and transportation for the output to the actual separation processes.

According to a development of the invention according to claim 14 this is done by the use of a medium of this kind, such a temperature and such a pressure that the ice to be separated portions and receive suspended in liquefied or schaumformigen medium and can be further promoted. This has the advantage that can be treated in a legal sense food without risk of being affected by use of an opposite device components and compositions of matter inert medium hydrous foods, especially meat.

An embodiment of the invention according to claims 29 to 31 with a perforated drum, a perforated plate or a perforated belt as portioning leads to a device in which the output part of a known device for coarse separation of soft and hard batch ingredients for continuously carrying out the separation process can be used , For this purpose the portioning element is provided with a sliding sealing lock which allows the portions located in the apertures can be discharged under conditions other than ambient pressure and temperature through the medium. By appropriate design of the sealing surfaces of the lock and the supply of the medium in this is a selective depletion of the openings can be achieved. In the development of the invention according to claims 36 to 40, a particularly simple connection of lock and collecting unit for the medium and separate portions results in such a way that the collection unit for the liquefied or foaming medium in the suction path of a conveyor unit is located, in which the suspension of medium and portions from the gate path of the medium is directly introduced. This prevents that the passing into the collecting unit batch components sediment and may clump together. The design of the output unit as shredder has the additional effect that any back or still cohesive portions are separated. In the further development of the invention, collector unit and output unit are combined such that the collector unit is designed as a screw conveyor with pressure-holding output unit. In this manner, largely on medium free portions and avoiding losses of medium.

In a further embodiment of the invention according to claim 15 (C02, Vulgo carbonic acid) is used in gaseous, liquid and solid (Vulgo carbonic snow) phase as a medium carbon dioxide. This is particularly useful when dealing with the substance mixture or the portions of food, particularly to battle material. By appropriate temperature and pressure settings in the portioning device, in the lock and in the collecting unit it is achieved that the food is not changed in its water content, be preserved by rapid freezing and converted into solid particles, which is suitable for further processing processes of great advantage.

In the following, a preferred embodiment of a device operating according to the inventive method, a device is described in detail with reference to the accompanying drawings and described for further explanation and for a better understanding of the invention.

1 shows schematically a plan view of an equipped with an apportioning device in the form of a perforated drum device, and

Figure 2 shows schematically a partial side view of FIG. 1

The embodiment according to Figures 1 and 2 consists of a crushing device 1, a portioning with a portioning element in the form of a perforated drum 2, Eortionieröffnungen 3 in the perforated drum, which receive the material batch components (portions) 4, a gate 5, comprising a discharge unit 6, and a collection unit 7, a conveyor 8, a compressor 9, valves 10 and 11, an output unit 12, a cooler 13, a separator 14, and a separating device 15. the pre-treated by grinding and / or screening material mixture is of the crusher 1, in this example, an output side of a somewhat modified meat grinder is pressed into the Portionieröffnungen 3 of the perforated drum. 2 The drive of the meat grinder is adjusted so that an approximately 80% fill of the Portionieröffnungen 3 results in correlation with the rotational speed of the drum. Through rotation of the drum counterclockwise the filled with the batch ingredients 4 Portionieröffnungen 3 enter into the sluice 5. There is fed via the valve 11 of the discharge unit 6 of liquid C02 as a conveying and treatment medium. Whose pressure is adjusted so that it is able during the residence time of the Portionieröffnung in the lock their content push out completely and be transported in the collection unit. 7 In the discharge unit will also be provided by uniform distribution of the medium flow on the entire width of the lock that the Portionieröffnungen be smoothly discharged. In the collecting unit, the expressed and divided now in portions batch components reach the conveying path of the liquid medium, the flow through the valve 10 and a corresponding driving speed of the conveying means 8 is set so that the portions to cool the one hand, almost to the temperature of the liquid medium can, but then evaporated as little medium. The conveying device 8 is in this example a centrifugal pump, finally separating the blades about still cohesive portions. In the output unit 12, the suspended particles in the medium mixture reach a rotary screen is drained through which the liquid medium and collected at the bottom. In the output unit 12 of the printing is further set so as to evaporate adhesive medium to the portions, so that these frozen unchanged over means connected to the output unit pressure sluice in relation to the input state, but sporadically output from the apparatus for further processing in the separating device 15 become. Liquid such as gaseous medium is liquefied through the condenser 13 back out of the respective cavities by the compressor 9 and fed back into the process. A separator 14, which is disposed cyclically removes water and other unwanted batch components continuously from the circulation of the medium.
