Description

Title of the invention: Machine for boning meat after cooking

[0001] The present invention relates to a machine for boning meat after cooking.

[0002] The present invention is designed for meat around the bones of web-footed birds or poultry bones and is particularly designed for duck bones. The machine treats with remarkable efficiency the meat surrounding the neck bones or the sleeves of ducks. It treats the meat surrounding the bones after cooking and in particular more particularly after candied meat. Cooking has the effect of destroying the chemical bonds of the meat and thus facilitating the release of the bones. Candied meat is a culinary preparation operation by cooking the meat in fat, particularly suitable for duck meat, which gives a very particular texture and taste.

[0003] Currently, for operators, several parts of meat are easy to debone and to valorize. Other parts attached to the bones are still very difficult to valorize: in particular the necks and the sleeves. The part of meat which remains attached to them after an initial cutting of the parts of the duck is then very difficult to separate mechanically without damaging the bone. Today, it requires precise manual work with operators who must scrape the bones to detach the meat from the bone. The invention thus allows the operator to better valorize the material, flesh, or tendon which is attached to the bones.

[0004] There are several machines in the prior art which describe machines for separating meat from bones, separation by vibration by US 2761479, separation by centrifugation by US 3896522, separation by fluid projection by US 2851362. These machines are not suitable for the specific case which interests us which is to separate cooked meat without damaging the bone and therefore without leaving bone residue in the recovered material.

[0005] There is currently no machine that can debone cooked meat without damaging the bone and without leaving bone residue. Indeed, the constraints are 1 - that the pieces of meat surrounding the bone are of variable sizes 2 - that the pieces of meat to be scraped or skinned are small, stringy and sometimes difficult to access 3 - that the bone surrounded by the meat is fragile and must not be damaged by the deboning action and leave bone residue in the recovered material 4 - that the recovered meat must remain in a shredded form without cutting or crushing. In short, the only existing solutions to date are manual work or grinding the whole into animal feed. The invention proposes an industrializable solution that makes it possible to recover the cooked meat surrounding poultry bones and more particularly necks and sleeves.

[0006] In a main aspect, the invention provides a boning jaw by making passing the bones between three very specific rollers described later. Each roller is specifically designed to act in combination with the other two and ultimately provide, through this combination, the ability to detach stringy, thin pieces of meat, well attached to bones of varying sizes. This combination makes it possible to separate both the muscular part from the bony part and to obtain shredded meat without cutting or crushing it.

[0007] In one aspect the invention provides a compact machine with a meat inlet chute, an improved cased jaw and two outlet chutes with the bones on one hand and the detached meat on the other. All held by a compact chassis. The assembly provides an efficient, compact machine that is easy to integrate into a production workshop.

[0008] A main objective of the invention is to offer operators an efficient, robust, compact, very low-power, secure machine which allows them to use meat still attached to the bones on parts which are difficult to detach manually.

[0009] An objective of the invention is to propose a machine which is economical and which falls within an acceptable cost price for this type of operation.

[0010] An objective of the invention is to provide a machine which is easy to clean and which meets current standards.

[0011] An objective of the invention is to provide a machine which is robust and which supports the passage of different bones of different calibers.

[0012] The invention will be better understood from reading the attached figures in which:

[0013] [fig. 1] represents a side view of the present invention

[0014] [fig.2] represents a top view of each of the three jaw-forming rollers according to the invention

[0015] [fig.3] represents a principle view of the three axes of the rollers in top view and aside

[0016] [fig.4] represents a front view of the jaw formed by the three rollers according to the invention

[0017] [fig.l] represents a side view of the present invention which is a machine with a frame (1) whose object is to animate and maintain three essential organs. Namely an introduction chute (2) for bones surrounded by meat (O) which slide pushed by the operator or in an automated manner into a jaw (10, 20, 30) constituted by three motorized rollers. As explained below, the rollers each rotate in a specific manner around their axis and each have particular volumes. The three axes of rotation are also specifically arranged. The assembly constitutes a jaw which separates the meat from the bones, the bones are evacuated on a specific outlet at the jaw outlet, called the bone outlet chute (3a) while the pieces of The detached meat falls as it passes through the jaw into a meat discharge hopper (3b) and slides vertically under the machine.

[0018] [fig.2] represents a top view of each of the three rollers (10, 20, 30) forming jaw according to the invention. The first roller from the top, called the de-shelling roller (30) is a conical roller, with a decreasing diameter between the entry and the exit of the bones surrounded by meat (O), which is composed of a series of rings which stack on top of each other on the axis A3 of the roller, the rings are each made of elastomer and have teeth (38) on the periphery. The teeth (38) of two successive rings are placed in a staggered pattern. The height of each tooth is typically of the order of a few millimeters. The entire roller therefore forms a surface with a large number of flexible hooks and a decreasing hardness towards the exit of the bones surrounded by meat (O), on the side of the bone exit chute (3a), which will, as explained below, succeed in detaching the meat from the bone. The meat passing under this roller is literally detached by the set of teeth which separate it from the surface of the bone.The second roller, which is positioned at the bottom right when viewed from the feed chute (2), is a drive roller (20). It is cylindrical in shape; with a diameter equal to the diameter of the support roller (10) described later but smaller than the diameter of the peeling roller (30). Its main function is, by means of the longitudinal rotation grooves (21) which groove it in a hollow, to serve as a support surface to rotate the bone surrounded by meat (O) when it passes into contact with the inside of the rotation grooves (21). This rotation of the bone surrounded by meat (O) in a direction opposite to the direction of rotation of the peeling roller (30) increases the effectiveness of the peeling action of the peeling roller (30).Furthermore, the longitudinal rotation grooves (21) can also serve as a gripping surface for the meat attached to the meat-surrounded bone (O) and thus also contribute to detachment. The third roller, called the support roller (10), is smooth. It is the same size as the drive roller (20). It rotates in the opposite direction to the drive roller (20). The support roller (10) is tangent to the drive roller (20). They are separated by a small thickness of the order of a millimeter. The two rollers rotate in opposite directions inwards and together contribute to rotating the meat-surrounded bone (0) and to gripping the pieces of meat partially detached by the peeling roller (30) to extract them through the small space which separates them and pass them into the meat discharge hopper (3b).

[0019] [fig.3] represents a principle view of the three axes of the rollers (A1, A2, and A3) in top and side view, the arrows on the axes represent the direction of rotation of the rollers. This figure also represents the movements (Ml and M3) of the rollers support (10) and hulling (30) rollers to which the horizontal (15) and vertical (35) return forces are applied respectively. The support roller (10) rotates around its axis (A1), the drive roller (20) rotates around its axis (A2), the hulling roller (30) rotates around its axis (A3). The two support rollers (10) and drive rollers (20) have axes of rotation (A1, A2) which are parallel, horizontal, and of opposite directions of rotation. The support roller (10) is movable horizontally (M1) to allow the passage of pieces of variable sizes, the horizontal return forces (15) have the objective of repositioning the support roller (10) to its initial position. The hulling roller (30) has an axis (A3) of rotation plunging downwards from a universal joint type articulation point (31) and plunging laterally towards the inside of the jaw in the space between the two lower roller axes.The peeling roller (30) is movable vertically (M3) opposite the articulation point (31). The further away from the articulation point (31) and therefore the further the meat-enclosed bones (O) advance in the jaw, the more the support force decreases to reach the nominal tension value of the vertical force (35). The plunging arrangement of the axis (A3) of the peeling roller (30) makes it possible to process all sizes of meat-enclosed bones (O) in combination with a vertical restoring force (35) as will be explained later. The plunging function of the axis (A3) inwards, as the axis (A3) rotates inwards of the jaw, has the function of applying a driving force which pulls the bone surrounded by meat (O) inwards of the jaw and thus mechanically advances it inside the jaw from the insertion groove (2) towards the bone outlet chute (3a).

[0020] [fig.4] represents a front view of the jaw formed by the three rollers according to the invention. It appears how the bone surrounded by meat (O) is inscribed inside the jaw formed by the three rollers which come to propose a jaw opening which gradually narrows. It also appears an essential point which is that the jaw is equipped with elastic return forces (15, 35) which push towards the inside of the jaw. The vertical return force (35) makes it possible to apply the necessary pressure on the bone surrounded by meat (O) to detach the meat. The horizontal return forces (15) towards the inside are applied on the structure holding the axis of rotation (A1) of the support roller (10) movable horizontally (Ml). The horizontal return forces (15) have the objective of allowing the passage of pieces of variable sizes and of repositioning the support roller (10) to its initial position.A downward vertical restoring force (35) is applied to the jaw outlet holding support of the vertically movable hulling roller (30) (M3) by a vertical restoring elastic force (35). The other end holding the rotation axis (A3) of the hulling roller (30) is mounted on a hinge point (31) which thus allows the roller to tilt differently depending on the . against the forces applied by the bones surrounded by meat (O) on the vertical elastic return force (35). The assembly therefore constitutes a converging jaw with return forces towards the inside of the jaw.

[0021] The present invention therefore relates to a machine for deboning bones surrounded by cooked poultry meat (O) comprising a chassis (1), a motor, an introduction chute (2) for bones surrounded by meat (O), a bone exit chute (3a) and a hopper for discharging the detached meat (3b), characterized in that the motor rotates three support rollers (10), drive rollers (20) and peeling rollers (30) along their respective rotation axis (A1, A2, A3) whose internal interstitial space forms a peeling jaw, the jaw is fed by the introduction chute (2), and spits out by the movement of its rotating rollers the detached meat into a meat discharge hopper (3b), by means of the grooves (21) scoring the periphery of the drive roller (20) or the teeth (38) present on the peeling roller (30).

[0022] The present invention therefore relates to a machine for deboning bones surrounded by cooked poultry meat (O), characterized in that the two support (10) and drive (20) rollers have axes of rotation (A1, A2) which are parallel, horizontal, and of opposite directions of rotation, rotating towards the inside of the jaw, the peeling roller (30) has an axis of rotation (A3) plunging downwards and plunging laterally towards the inside of the jaw in the space between the two axes of the lower rollers.

[0023] The present invention therefore relates to a machine for deboning bones surrounded by cooked poultry meat (O), characterized in that horizontal return forces (15) towards the inside are applied to the structure for holding the rotation axis (A1) of the horizontally movable support roller (10) (M1) and a vertical return force (35) towards the bottom is applied to the jaw outlet holding support of the rotation axis (A3) of the vertically movable peeling roller (30) (M3).

[0024] The present invention therefore relates to a machine for deboning bones surrounded by cooked poultry meat (O), characterized in that the vertical return force (35) applied to the axis of rotation (A3) of the peeling roller (30) is a vertical elastic return force positioned opposite the articulation point (31) at the bone outlet chute (3a) making it possible to reduce the support force as the bones surrounded by meat (O) advance.

[0025] The present invention therefore relates to a machine for deboning bones surrounded by cooked poultry meat (O), characterized in that the support roller (10) is smooth, it is of the same size as the drive roller (20), it rotates in the opposite direction to the drive roller (20), the support roller (10) is tangent to the drive roller (20), they are separated by a small thickness of the order of a millimeter, the support roller (10) is horizontally movable (Ml) to allow the passage of detached meat of variable size, the horizontal return forces (15) towards the inside allow the support roller (10) to return to its initial position tangent to the drive roller (20).

[0026] The present invention therefore relates to a machine for deboning bones surrounded by cooked poultry meat (O), characterized in that longitudinal rotation grooves (21) hollowly groove the surface of the drive roller (20) in order to serve as a support surface for driving the bone surrounded by meat (O) in rotation when the bone surrounded by meat (O) passes into contact with the inside of the rotation grooves (21).

[0027] The present invention therefore relates to a machine for deboning bones surrounded by cooked poultry meat (O), characterized in that the peeling roller (30) is a conical roller of decreasing diameter as it progresses from the entrance to the jaw, composed of a series of rings which stack on top of each other on the axis A3 of the peeling roller (30), the rings are each made of elastomer and have teeth (38) on the periphery, the teeth (38) of two successive rings are placed in a staggered pattern, the height of each tooth is of the order of a few millimeters.

[0028] It is possible to present variants to the present without departing from the scope of protection of the present invention.
