Definitions

  • the invention initially relates to a device for forming a strand-like food, in particular a piece of meat, with a) a pressing chamber which is delimited by walls, at least one of which is movable by means of a pressing device and is designed as a press ram, whereby the pressing chamber from an initial state with a first enclosed volume can be converted into a final state with a second enclosed volume, b) a feed device for feeding the food into the pressing chamber, c) a discharge device for removing the food from the pressing chamber.
  • the invention also relates to a method for shaping a strand-like foodstuff, in particular a piece of meat.
  • the food is usually cut into slices by means of a cutting machine and then transferred to a packaging device that packs a certain number of the cut slices together in one package.
  • the number of slices contained in a package is based on the amount specified on the package, with the amount of the food actually contained in the package only being allowed to deviate from the specified amount within a legally prescribed range.
  • the device comprises a pressing chamber, comprising six walls, three of which are designed as movable pressing rams.
  • a wall forming a base plate of the pressing chamber is firmly anchored.
  • a rear side of the pressing chamber is also designed as an immovable wall.
  • the food to be formed is fed to the pressing chamber by means of a conveyor belt, the food being conveyed from a first level by means of the conveyor belt to an edge area of the conveyor belt and then falling onto the base plate, which is arranged vertically below the conveyor belt.
  • two foodstuffs separated from one another by means of a separating part are formed at the same time by means of the device by moving the walls designed as press rams.
  • a wall forming one side is moved in such a way that an opening cross-section of the press chamber is exposed.
  • the two shaped foods are then conveyed out of the pressing chamber by means of a movement of the opposite pressing ram.
  • DE 102016 122 126 A1 also discloses a device for shaping a foodstuff.
  • the device comprises a press chamber with two walls designed as press rams, by means of which the food can be shaped.
  • the food is fed to the pressing chamber by means of a conveyor belt which is oriented at an angle to a horizontal and has a first direction of movement. This is followed by the molding process.
  • a wall forming one side is moved to reveal an opening cross section, while a pressing ram arranged on an opposite side is moved in order to convey the food out of the pressing chamber and transfer it to the conveyor belt, which is in a - compared to the first direction of movement - opposite direction of movement and also at an angle to the Is aligned horizontally.
  • a feed opening of the pressing chamber thus corresponds to a discharge opening of the pressing chamber.
  • DE 202005018374 U1 describes a device for shaping a foodstuff which has a pressing chamber and a conveyor belt for feeding the food into and out of the pressing chamber.
  • the device has a means for picking up the food, which is coupled to the conveyor belt, so that the means is moved along with a movement of the conveyor belt.
  • the conveyor belt By means of the conveyor belt, the food lying on the means is conveyed to a pressing chamber, which shapes the food by means of its press plunger. After the molding process, the food is conveyed out of the pressing chamber by the agent.
  • DE 2 140585 A discloses a device for pressing meat products, in particular pork belly, with a plurality of rollers aligned parallel to one another, which form a press gap between them through which the meat product to be pressed is guided.
  • a conveyor belt on which the meat product rests is used as the conveying device.
  • opposite pairs of rollers are arranged in such a way that a press nip formed between them becomes increasingly smaller in the feed direction.
  • a pressing chamber in the sense of a device of the type on which this application is based, in which the food stands still during the pressing process, does not exist.
  • the previously known device also does not work when the conveyor belt is stationary, since otherwise no further movement of the meat product through the roller pairs would be possible, but such further movement is essential to achieve the pressing effect.
  • the conveyor belt is at a standstill, a relative sliding movement would have to occur between the surface of the conveyor belt and the upper press rollers, which cannot be carried out.
  • the feed device and / or the discharge device is a conveyor belt which at least partially covers one of the walls in an interior of the pressing chamber.
  • enclosed volume is understood to mean a volume that is enclosed by a surface of any shape, with at least parts of the enclosing surface not necessarily having to be physically present. Rather, the surface can be partially formed by planes that are formed by a conceptual extension of existing components, with sections of such planes with other conceptual planes on the one hand or the physical components on the other hand defining the volume.
  • the “initial state” of the pressing chamber is understood to mean a state of the pressing chamber in which the pressing chamber is at least dimensioned such that a food to be shaped can be placed in the pressing chamber without the food being deformed. It is preferably provided that the walls of the pressing chamber are arranged at a distance from a surface of the food in the initial state. However, it is also conceivable that the walls are at least partially in contact with the surface of the food. In particular, the pressing chamber in its initial state is not necessarily in that state in which it encloses the largest volume. The initial state can therefore be dependent on a volume of the food to be formed.
  • the “final state” of the pressing chamber is understood to mean that state of the pressing chamber in which the same is in contact with the food to be molded, in particular transmits pressing forces to it, whereby the same was converted into its molded state.
  • a molding process in which the food is transferred from an unshaped state to a molded state is therefore carried out in the course of a transfer of the pressing chamber from its initial state to its final state.
  • the device according to the invention has many advantages.
  • a particular advantage of the device is that the food to be shaped can be fed into and removed from the pressing chamber in an automated manner, that is to say without manual intervention. In this way, it is advantageously possible to minimize the expenditure on personnel as well as the expenditure of time for transferring the shaped food out of the device, so that a throughput of the device is improved.
  • the wall covered by the conveyor belt forms a bottom of a pressing chamber. In comparison to the known devices, none is provided in addition to the conveyor belt Ingestion necessary to absorb the food. Rather, the food can simply be placed on the conveyor belt.
  • the device according to the invention can advantageously be integrated particularly easily into an existing conveyor system.
  • the conveyor system is formed from a plurality of devices, in particular a cutting device and a device for molding and a plurality of conveyor belts connecting them, into which the device according to the invention can be integrated particularly easily.
  • the food therefore only has to be placed once on a first conveyor belt.
  • the shaped food can be conveyed to the cutting device by means of the same or by means of a further conveyor belt, without having to re-align or remove the food from the device beforehand.
  • the food already occupies a precisely defined position on the conveyor belt of the device, which means that the food can be passed on without repositioning even in the event of further transport.
  • the conveyor belt can be moved parallel to a direction in which the compression chamber has a greatest length extension.
  • a conveyor belt can advantageously be used, the width of which - measured perpendicularly to a direction of movement of the same - essentially corresponds to a width of the foodstuff, preferably exceeds it.
  • a length of the device here essentially corresponds to or exceeds a length of the food to be shaped.
  • the food can be converted into the desired shape by means of a one-time shaping process - without dividing it into several pieces beforehand, whereby a division is also entirely conceivable in the case of particularly long food.
  • the conveyor belt can be moved perpendicular to the direction of the greatest longitudinal expansion of the pressing chamber.
  • the width of the conveyor belt should correspond to the length of the pressing chamber in the initial state.
  • the conveyor belt encloses a wall of the pressing chamber between an upper run and a lower run.
  • the conveyor belt runs around the wall of the press chamber so that the same is covered by the conveyor belt.
  • the wall that is covered by the conveyor belt is not designed as a press ram, but merely as an immovable counterpart to an opposing press ram that absorbs the pressing force perpendicular to the conveyor belt, so that the conveyor belt does not result in a molding process deformed by movement of the enclosed wall.
  • the pressing chamber can therefore be combined particularly easily with a conventional conveyor belt.
  • a width of the conveyor belt measured transversely to a direction of movement of the conveyor belt is greater than a width of the pressing chamber measured transversely to the direction of movement of the conveyor belt, preferably in its final state, more preferably in its initial state.
  • the conveyor belt accordingly protrudes over the edge areas of the pressing chamber. In this way it can be ensured that the food, preferably at least in the final state of the pressing chamber, only comes into contact with the conveyor belt in order to enable the food to be transported. This can prevent the food from sticking to a wall next to the conveyor belt.
  • the object mentioned at the beginning is achieved based on a method for shaping a string-shaped foodstuff, in particular a piece of meat, in that the food is conveyed into and / or out of the pressing chamber by means of a conveyor belt, the conveyor belt at least one wall of the pressing chamber partially covered.
  • the method according to the invention here initially comprises four steps: In a first step, a pressing chamber delimited by the walls is opened by moving at least one of the walls relative to at least one other of the walls, thereby releasing an opening cross-section. In the initial state as well as in the final state, the pressing chamber encloses the food.
  • At least one of the walls must therefore be movable in such a way that an opening cross-section is released which essentially corresponds to a cross-section of the food, preferably is slightly larger so that the food can be introduced into the pressing chamber as collision-free as possible is.
  • the food is introduced into the pressing chamber through the opening cross-section, preferably by means of the feed device.
  • the opening cross-section of the pressing chamber is closed again and the food is transferred from an unformed state to a shaped state by moving the walls of the pressing chamber designed as a press ram. The pressing chamber is therefore in its final state.
  • an opening cross-section of the pressing chamber is released and the shaped food is discharged from the pressing chamber through this opening cross-section.
  • the food is preferably discharged by means of the discharge device.
  • an opening cross-section for feeding a second, downstream food item is released at the same time and can be proceeded in a similar manner for the following food items.
  • the method can advantageously be accelerated in this way.
  • An advantageous embodiment of the invention provides that at least one wall of the pressing chamber, preferably two walls arranged on opposite sides of the pressing chamber, can be moved transversely to a direction in which the respective wall can be moved when the pressing chamber is moved from the initial state to the final state or are, whereby an opening cross-section for the supply of the unformed food and / or the discharge of the molded food is created.
  • a wall which forms a top side of the pressing chamber and which is in the form of a wall that can be moved in a first direction Press ram is formed is coupled to two walls that form sides of the press chamber.
  • the walls forming the sides can be designed as press rams which can be moved in opposite directions.
  • the pressing devices are designed, for example, in the form of an electromechanical cylinder that is driven by a servomotor. It is also conceivable that the pressing devices are formed by hydraulic cylinders or linear motors. In any case, it is particularly advantageous if the press devices can be operated in a pressure-controlled manner, so that a movement of the press ram is automatically terminated when a predetermined final pressure is reached.
  • a particularly advantageous further development of the device according to the invention provides that a temperature of the food, at least in edge areas, is lower than a temperature of the food in a core area.
  • a shape of the food obtained by means of the molding process is thereby advantageously retained longer, so that the food is still in a molded state when it reaches a downstream cutting machine and can nevertheless be sliced with conventional cutting machines. It is preferably provided here that the temperature of the food in the edge areas is below 0 ° C. In particular, a restoring force of the food, which ensures that the food returns to its unshaped state, is thereby reduced.
  • pressing forces are transmitted from the food via the conveyor belt into a wall that supports it.
  • the conveyor belt is preferably only used to move the food and does not itself exert any pressure on the food.
  • Another embodiment of the invention provides that the food is transferred by means of the conveyor belt to a further conveyor belt, which transfers the food to a device and / or the conveyor belt takes over the food from another conveyor belt on which the food is placed.
  • the device can be connected to an existing conveyor system in a particularly simple manner.
  • a width of the conveyor belt can match a width of at least one further conveyor belt.
  • a direction of movement of the conveyor belt coincides with a direction of movement of at least one further conveyor belt.
  • the device can in particular be a cutting device, a packaging device or a scale.
  • a feed position of the food on the conveyor belt after completion of the molding process essentially corresponds to a discharge position of the food on the conveyor belt.
  • the food to be shaped only has to be placed on a first conveyor belt once. It is preferred here if the feed position of the food is specified by means of a positioning device, preferably in the form of a guide rail, e.g. in the middle of a first conveyor belt.
  • the food does not have to be realigned on a conveyor belt in this way before it reaches a cutting machine, which is arranged temporally and spatially downstream of the device for shaping, so that one work step can be saved.
  • the food can therefore be placed on a first conveyor belt, shaped by means of the device and cut into slices by means of a cutting machine and then typically removed as a packaged portion without the need for a further positioning step.
  • the food is conveyed by means of different conveyor belts, the feed position of the food being retained even when it is transferred to a subsequent conveyor belt.
  • a preferred embodiment of the invention provides that at least one wall designed as a press ram is perpendicular and / or parallel to a direction of movement of the food in which the food is fed to the press chamber, preferably in the direction of movement or perpendicular thereto, during the introduction of the food into the press chamber, is moved so that a distance between the wall and an opposite wall of the pressing chamber is reduced.
  • the size of the pressing chamber can be adapted to the food before the food is finally positioned in the pressing chamber.
  • the time required to shape a foodstuff can be reduced as a result, since the traverse paths of the press plungers are reduced in a subsequent shaping process.
