Definitions
- the invention relates to a device designed and set up for obtaining back meat or parts thereof from back parts or parts thereof from poultry carcasses with a neck side and a hip side as well as an outside and an inside of the body.
- the invention further relates to a method for obtaining back meat or parts thereof from back parts or parts thereof from poultry carcasses with a neck side and a hip side as well as an outside and an inside of the body.
- Such devices and methods are used in the animal processing industry, in particular in the poultry processing industry, to obtain back meat or parts thereof from back parts or parts thereof from poultry carcasses (also referred to as back parts in the following).
- back meat is obtained as an integrated process that is not carried out separately in the industrial processing of poultry.
- front-halfs In addition to the production of “front-halfs” and “back-halfs” in advance of the actual filleting, “front-halfs” are often further segmented, as this is where the largest muscle areas of poultry are usually present.
- the chest and the back of the front half of the poultry are separated from each other by a separating cut, starting on the chest side of the neck along the breathing fold, i.e. along the side of the poultry carcass along the ribs and through the ribs in the direction of the hips.
- the back side includes the back part.
- the complex geometry of the poultry carcasses is broken up, creating intermediate products that are much easier to handle and process.
- the focus on the different end products to be obtained is also taken into account when the poultry carcasses are pre-cut.
- By breaking up the poultry carcass into sub-segments it is possible to provide suitable devices and processing stations which are adapted to the respective geometries of the segments in order to achieve the highest possible yield of the desired end products.
- the main end product is the pectoral muscle or the breast fillet, which dominates the upper body in its massive form.
- the focus has long been on harvesting the pectoral muscle or breast fillet as efficiently as possible, although there are other meat areas that can be harvested or in view of the rising meat prices and the fullest possible recycling the poultry carcasses should also be harvested.
- Front halves are regularly segmented into a breast cap and a back cap in order, for example, to extract meat components that adhere to them.
- front half is further segmented to produce a breast cap and a back cap, or also called the back part, there is no possibility of gaining the back meat in the course of the breast fillet extraction.
- the back part must therefore be processed separately, which means that separate back meat would have to be obtained, which in practice is not done by machine.
- a method and a device are known from WO 2008/078982 A1 in which the upper back area is skinned and filleted.
- the starting product forms an entire poultry carcass, in which the breast cap and the wings have already been separated.
- the processing takes place while the poultry carcass is suspended from the legs, placed on a product carrier, and transported into a processing plant.
- the hanging arrangement of the poultry part carcass on the product carrier offers only a low level of stability in order to be in engagement with the cutting means provided for this purpose.
- the process of obtaining back meat from separated back parts is not carried out automatically.
- the resulting back parts If further processing takes place at all, further processing is carried out manually, in that a sequence of cuts is usually carried out along the spine, starting at the end of the back part on the hip side in the direction of the neck. If the shoulder blades have not been removed from the back parts in advance, the end product is a meat product that includes both shoulder blades. Such products are very popular in the fast food industry, for example.
- the manual separation process is time-consuming, costly and often only provides a low yield from the back parts.
- a manual processing of the back parts due to the complicated cutting sequence, harbors a high risk of injury.
- the positioning and holding of the back parts on automated devices are associated with a high level of design and manufacturing effort due to the complex geometry of the back parts.
- the invention is therefore based on the object of making available a device which ensures a safe, reliable and yield-efficient extraction of rear meat or parts thereof from back parts or parts thereof.
- the task remains to propose an appropriate procedure.
- the back part comprises a spine or parts thereof and a rib structure with at least vertebral pairs of ribs or parts thereof, and wherein the back flesh contains in particular at least one shoulder blade, comprising one for transporting the back parts or parts thereof along a transport path with a central axis M in the transport direction T set up transport conveyor with a Drive unit and a transport element for conveying at least one holding element arranged on the transport element for receiving the back part or parts thereof during the at least regional transport along the transport path, a first cutting means arrangement arranged along the transport path in the region of the transport element with at least one loosening means for loosening the back flesh at least regionally essentially along the rib structure, a second cutting means arrangement arranged downstream of the first cutting means arrangement along the transport path in transport direction T in the area of the transport element, with at least one cutting knife for at least regionally cutting off the incised back flesh or parts thereof at least substantially along the spine, the holding element being formed , in such a way
- the device, in particular the holding element can, however, also be used to arrange back parts of other poultry such as ducks, geese, turkeys, pigeons or quails, the size of the holding element having to be adapted in each case.
- the apparatus would also have to adjust the dimensions of the first and second cutting means assemblies in order to process different types of poultry.
- “Back parts” in the sense of the invention is to be understood as a separately separated area of the “front halfs” of poultry carcasses, which is formed in particular from the back area of the front poultry halves of the poultry carcase.
- the back part in particular comprises at least one area of the spine with at least one area of the ribs and the back flesh connected to it.
- the back flesh preferably has at least one shoulder blade, particularly preferably two shoulder blades, that is, one shoulder blade is present on each side of the spine.
- the spine of poultry also generally has a bone rod, at least in some areas, called notarium in technical jargon, which is formed by a local thickening of the fused thoracic vertebrae.
- the spine in the sense of the invention thus also includes the local thickening of the bone rod.
- the thickening must be left out during machine processing in order, for example, to avoid bone splinters due to damage to the bone rod.
- the “inside of the body” and the “outside of the body” in the sense of the invention are alternatively also referred to as the inside area of the poultry or the back part and the outside area of the poultry or the back part.
- the inside of the body thus in particular forms the inner cavity of the chest cavity of the poultry with the vertebral ribs, while the outside of the body identifies the outer, externally accessible area with the skin or meat.
- the "neck side” and the "hip side” of the back is determined by the segmentation of the poultry carcass.
- the neck side of the back is the side that is produced by a cut in the neck area of the poultry, while the hip side is produced by a cut in the hip area.
- the back part is thus determined by the anatomy and the segmentation carried out on the poultry carcass.
- Such transport conveyors with the transport element are particularly preferably belt, belt, chain, carriage and / or roller transport devices.
- the transport direction T also forms the sequence in which the respective processing stations are arranged one after the other.
- the transport path can preferably be endless and can run in the plane at different heights.
- the transport conveyor can be designed as a wheel conveyor. This means that the holding elements are arranged on the circumference of a driven wheel and the respective processing stations for extracting the back meat are positioned in the vicinity of the engagement of the wheel, whereby the corresponding processing and the extraction of the back meat takes place.
- the arrangement of the cutting means arrangements “in the area of the transport element” in the sense of the invention means that the first and the second cutting means arrangements are positioned such that they can be in engagement with the holding element conveyed on the transport element with the back part.
- a “first cutting means arrangement with at least one release means” in the sense of the invention is to be understood in an advantageous embodiment not only as a first cutting means arrangement with a single release means.
- the first cutting means arrangement can in particular also consist of two spatially separated, separate loosening means be formed, with the purpose of cutting the back meat essentially along the rib structure.
- the loosening means is, for example, a scraper, a knife or a tool in order to loosen the back meat from the rib structure, that is to say to remove it from the rib structure at least in some areas.
- Essentially along the rib structure means in the context of the invention that the back meat either loosened exactly along the rib structure or at a small distance along the rib structure, that is, from the rib structure in a range of 0.5 mm to 3 mm .
- "At least partially loosening" the back meat by means of the loosening agent means in the context of the invention that the back meat is loosened completely, that is, over the entire length of the central axis M, or a partial area of the back meat is loosened.
- the back meat is preferably not yet separated, that is, the back meat remains connected to the back part at least in one area.
- “Loosening” is thus to be understood, for example, as the incision of the back meat along an area predetermined by the arrangement of the first cutting means arrangement.
- a complete severing of the back meat or parts thereof by means of the first cutting means arrangement can already be expedient.
- the loosening can also take place, for example, by scraping, shearing and / or peeling off the back flesh in the specified area and is encompassed by the term “loosening”.
- the severing of the incised back flesh "at least essentially along the spine” means in the context of the invention, either exactly along the spine, that is, in each case directly in the course of the spine, or with slight deviations along the spine, ie with a deviation from the spine around a maximum of ⁇ 25 mm, which however depends on the size of the poultry carcase. Separating within the meaning of the invention includes, for example, scraping, peeling off, cutting off, detaching, shearing, etc. It is only essential in the context of the invention that the second cutting means arrangement is designed in such a way that the most complete possible removal of the back flesh from the rib structure and / or the spine by means of the cutting knife takes place.
- the device according to the invention through the combination of the two cutting means arrangements in connection with the holding element, ensures that the back meat to be separated from the back parts can be separated efficiently, reliably and with high quality, i.e. that the back meat is obtained from the back part as completely as possible and free of damage . Furthermore, it is ensured that the back meat is not contaminated when the back meat is obtained, since the back part is securely positioned on the holding element. Contaminants are, for example, bone splinters from the remaining part of the back, which can occur in the event of improper positioning and further processing.
- the device has a structure with low complexity and, associated therewith, a reduced procedural effort when harvesting the back meat.
- the device It is also advantageous to subdivide the device into a first cutting means arrangement and a second cutting means arrangement, because this initially results in a clean loosening or loosening or detachment of the back flesh from the back part, and the further downstream second cutting means arrangement ensures reliable separation of the back flesh from the back part guaranteed. In this way, high quality back meat that is free from contamination can be obtained.
- the holding element also ensures that the back part has a secure fixation at every point in time when it passes through the device, whereby constant results are given in the extraction of back meat.
- the device is designed in such a way that the back parts can be cut in areas by the at least one loosening means of the first cutting means arrangement, and that the back meat cut in some areas can then be separated by means of the cutting knife of the downstream second cutting means arrangement, results in a device structure with a low degree of complexity, whereby the Design and manufacturing effort is reduced, which in turn results in a cost-effective production of the device.
- the upstream first cutting means arrangement also increases the availability of the back meat to be detached, since it allows the back meat located on the outside of the body of the back part to be deliberately detached or cut, so that in the downstream, second cutting means arrangement, the separation can take place with a predetermined cutting sequence, which leads to determinable yields.
- the means used for this are specially selected for the respective processes, which contributes to efficient processing.
- the device is preferably free of hydraulic and / or electronic control means in the context of the active processing of the back parts, which is a cost-efficient machining is also beneficial by reducing investment and maintenance costs.
- the device according to the invention thus leads to a higher quality of the back meat obtained, an increased yield and low production and operating costs of the device.
- the subdivision of the device into a first cutting device arrangement and a second cutting device arrangement also offers the advantage that the two cutting device arrangements can be arranged downstream along the transport path, whereby in both arrangements the back parts can be guided on the same holding elements and at the same processing speed and the respective cutting device arrangements can be performed the exact specifications can be set.
- the holding element enables a specific and needs-based arrangement of the back part. Since the back part can be arranged in a non-positive and / or form-fitting manner, the back part is reliably secured over the entire transport route. In this way, the further device components can be aligned accordingly in order to carry out targeted processing, in particular the back part is reliably secured against high shear forces that occur. The loosening and separation of the back flesh from the back part leads to mechanical stress, but the fixation on the holding element prevents a change in position.
- a preferred embodiment is characterized in that a pressing device with a pressing element is arranged upstream of the first cutting means arrangement and is set up to press the received back part with the pressing element from the outside of the body onto the holding element. This ensures that the back parts are each arranged at the same point on the holding elements before being loosened by means of the first cutting means arrangement. This leads to even results in the extraction of the back meat and reduces incorrect cuts, which leads to undesired rejects.
- the pressing device is further preferably arranged during the process of positioning or fixing the back part on the holding element in order to support a reliable and desired positioning of the holding element.
- a pressure device also supports reproducible and as constant as possible results in the extraction of back meat, since this means that the back parts are preferably arranged with a uniform pressure on the holding elements.
- the pressing device also facilitates the positioning of the back parts on the holding elements, since the back parts only have to be placed on the holding elements and can then be automatically positioned by the pressing element. In this way, such devices with a pressing device are suitable for automated operation and thereby enable a higher throughput of back parts.
- the pressing device is particularly preferably arranged in the area of the equipping of the device with back parts, that is to say in front of the non-positive and / or form-fitting arrangement of the back part.
- the pressing element is preferably designed to be resiliently mounted in order to press the back part uniformly and in particular with a maximum adjustable force on the holding element.
- the holding element is designed in such a way that the back part or parts thereof can be arranged in the transport direction T along the transport path with the neck side first on the holding element. Due to the complex geometry of the back parts, the arrangement of the back parts on the neck side on the holding element ensures that the downstream incision reliably loosens the back meat by means of the first cutting means arrangement.
- the neck side of the back part of poultry carcasses is usually narrower than the hip side and the hip side area regularly comprises the higher proportion of back meat. With the neck-side arrangement of the back part on the holding element, the incision is thus made by means of the first cutting means arrangement, starting from the narrower to the wider area.
- the rib arches of poultry naturally run inclined, that is to say arched, so that the at least one release means runs along the ribs and is preferably designed in such a way.
- the first cutting means arrangement in particular the at least one release means, is designed to be deflectable against a spring force by means of a spring element.
- the at least one loosening means yields against the spring force. This prevents possible damage to parts of the device as well as to the back parts, in particular to the rib structure, as a result of which the risk of contamination, for example bone splinters, is avoided.
- the dissolving agent cuts as close as possible to the rib structure over the entire course of the back part, which leads to high yields.
- the at least one release means can furthermore preferably be resiliently mounted by means of the spring element in such a way that the at least one release means is designed and configured to be evasive perpendicular to the transport direction T if necessary, for example in the case of an obstruction due to bone parts.
- An expedient embodiment of the invention is characterized in that the first cutting means arrangement is formed from a pair of at least substantially opposing release means, the release means being arranged on both sides of the transport path in such a way that a gap A between the two release means in the area of the central axis M. to spare the spine is formed by the opposing loosening means.
- the size of the gap A is preferably designed to be adjustable between the release means.
- the distance between the gap A is more preferably in the range between 2 and 24 millimeters.
- the release means have a curved shape and are designed to cut into the back part or parts thereof in the course of the transport direction T starting from the neck side and to leave the back part or parts thereof again on the hip side, whereby the loosening agents loosen the back meat along the rib structure.
- the curved shape of the loosening means preferably corresponds to the natural shape of the rib structure of poultry, whereby a high yield of the detachable back meat can be achieved.
- the size and The inclination of the respective shape of the loosening agent depends on the back part to be processed, in particular on the type of poultry.
- the loosening means are particularly preferably selected in terms of size and arrangement in such a way that they loosen as close as possible above the rib arches, starting from the outside of the body of the back part, or, depending on the design of the loosening means, cut into them. In this way, the highest possible yield of back meat occurs.
- At least one of the release means is adjustable in height relative to the holding element and / or in the distance from the central axis M.
- the at least one release means can be adjusted exactly to the respective specifications of the back part of the poultry carcass to be processed, in particular different height adjustments have to be made for different types of poultry to be processed.
- the device comprises at least one sensor device to detect the dimensions and / or geometry of the back part, around the first and / or second cutting means arrangement, or the at least one triggering means, in accordance with the recorded data in the height arrangement and / or set at the distance to the central axis M and to align.
- a preferred development of the invention is characterized in that the at least one cutting knife is designed and set up for completely cutting off the back meat at least essentially along the spine.
- the area of the spine is usually left open, so that there is still a connection of the back flesh with the back part in this area.
- the at least one cutting knife cuts the incised and loosened back meat from the remaining connections with the back part, as a result of which the back meat is essentially completely separable.
- the at least one cutting knife is designed and configured to be adjustable in height relative to the holding element. Due to the adjustability, the at least one cutting knife is exactly on the respective specifications of the back part of the poultry slaughter body to be processed can be adjusted; in particular, different height adjustments are to be made for different types of poultry to be processed.
- the device comprises at least one sensor device to detect the dimensions and / or geometry of the back part, around the first and / or second cutting means arrangement, or the at least one cutting knife, according to the recorded data in the height arrangement and / or set at the distance to the central axis M and to align.
- the at least one cutting knife is designed to be deflectable against a spring force by means of a spring element.
- a uniform loosening takes place by means of the cutting means of the second cutting means arrangement, since if the force is applied too high, the at least one separating knife gives way against the spring force.
- the at least one separating knife cuts as close as possible to the spine over the entire course of the back part, which leads to high yields.
- the at least one separating knife can furthermore preferably be resiliently mounted by means of the spring element such that the at least one separating knife is designed and configured to be deflectable perpendicular to the transport direction T if necessary, for example if there is an obstruction by bone parts.
- the at least one cutting knife is V-shaped.
- the at least one V-shaped separating knife corresponds to the contour of the spine of the back part or the shape of the notary, the bone rod of the fused thoracic vertebrae, which leads to reduced wear of the separating knife and, on the other hand, prevents damage to areas of the back part .
