  • Patent number: 6406366
    Abstract: An apparatus and method for removing a pin bone or pin bones from a fillet of fish. The apparatus of the present invention uses a rotating stack of individual disks that are engaged by a shaft, oscillate axially and are timed to alternately tilt in a rapid fashion so as to effect the action of multiple pairs of tweezers. The pin bone is disposed between a pair of tweezer or two adjacent rotating disks and pulled out of the fillet by the rotating disks. The rotating stack of individual disks operates at different speeds in an operation circle to enhance the operational efficiency.

  • Patent number: 6383069
    Abstract: Apparatus and methods for performing multiple automated poultry processing operations upon a slaughtered animal or a part thereof via a single machine is described. The machine contains at least two rotary processors in a single frame. A covering surrounds the processors. A venting processor cuts out and removes the vent to a slaughtered animal and in the process removes unwanted fecal or other material from the exterior and the interior of the carcass. The processors integrated into the single machine are coupled by a conveyor line following a preferably generally S-shaped route that carries the carcasses amongst the processors, preferably positioning the carcasses at the optimum registration point for the operation performed by the particular processor.

  • Patent number: 6338673
    Abstract: Apparatus for electrical stunning and killing poultry comprises a conveyor (31) and means for applying electrical voltage across the heads of the birds (3; 37; 42). In one embodiment, means are also provided for applying a voltage between the bird's head and rear by means of a further electrode (4). In this case, a two stage stun and kill process is used, with the bird being stunned by a voltage applied to it across its head and then killed by a voltage applied between its head and rear, causing fibrillation of the heart. The apparatus may also include means (5; 34) for restraining the bird's heads and/or facilitating contact of the bird's heads with the electrodes. The electrodes themselves may take a number of forms, including dry resilient foam covered by a conductive wire mesh, or a number of parallel sprung pins, or a rail along which the bird's heads slide, or a conductive endless belt. A pair of manual stunning tongs (61) is also described.

  • Patent number: 6338674
    Abstract: The invention provides a process and anal seal for sealing the anus of the carcass (10) of a slaughtered animal. The anal seal includes a plug (15) for insertion through the anus so that tissues (11) contract behind the plug, a clamp (20) movable towards the plug to clamp the tissues behind, and retaining means (40) to hold the clamp in its clamping position. The plug (15) is conical and has a back end (17) so that the clamp which is in the shape of a clamping disc (22) clamps against periphery (18) of the back end of the plug. The clamp (15) can slide on a stem (32) extending from the back end of the plug. The retaining means (40) can comprise biasing means (48) or a latch (41) to hold the clamp in its clamping position. An applicator tool (60) can mount the anal seal during insertion of the plug into the rectum and move the clamp from a retracted position to its operative clamping position.

  • Patent number: 6336856
    Abstract: A loin puller for processing a carcass-half comprising a loin and a flank partially separated by cutting, the loin comprising a layer fat to be trimmed off. The machine has a frame which is fixed an elongated rectilinear working surface intended to receive and support the loin of the carcass-half to be processed. A conveying system is mounted onto the frame above the working surface for engaging and pressing the loin and moving it together with the flank connected thereto up to a cutting zone. An arcuate cutting blade is mounted to the frame in the cutting zone for engaging the loin when the frame is moved by the conveying system and for cutting the layer fat to be trimmed off the same. Advantageously, the frame is devised to let the flank fall down from the working surface while the carcass-half is moved by the conveying system. As a result, more visibility is left for evaluating an optimum position for the cutting blade.

  • Patent number: 6328645
    Abstract: A poultry processing machine is provided which automatically vents and opens the poultry, eviscerates the poultry, displays the poultry for inspection, and either provides a normal or radical clean out procedure to the poultry. When the poultry is being physically processed, it is maintained in a generally stationary position with respect to the surface supporting the poultry processor to provide for uniform positioning of the poultry on the conveyor. Further, the poultry is positioned in a generally horizontal position during the venting and opening, eviscerating and cleaning procedures, to facilitate removing the unwanted materials from the poultry without increasing the risk of contamination. The eviscerating station uses an eviscerating tool which includes an opening sized to receive the viscera package therethrough during the eviscerating process to prevent damage to the viscera package.

  • Patent number: 6322437
    Abstract: A method for obtaining muscle flesh from beheaded fish by severing muscle flesh from dorsal and/or ventral spokes together with fins and fin holders as well as from ribs or lateral vertebral appendages and a vertebral column. The method uses an apparatus having severing means for severing the muscle flesh from the dorsal and/or ventral spokes which include a first tool and a second tool, each of which is provided with pairs of cutting means. The cutting means of the first tool and the associated bone guides can be controlled in height with respect to the position of their cutting edges and guide edges, respectively, relative to a conveying path. The cutting means of the second tool are constructed as knife blades arranged between the bone guides with the cutting edges pointing towards the conveying path. The knife blades are elastically displaceable away from the conveying path.

  • Patent number: 6322438
    Abstract: Previously eviscerated poultry carcasses with legs and backs remaining are suspended from shackles (25) by their legs and moved in sequence along a processing path. The backs are received on a surface conveyor (18) having parallel conveyor flights (36, 37), so that the rounded portions (31) of the surfaces of the backs (30) seek the space between the conveyor flights, thereby tending to center the carcasses moving along the poultry path. The backs are turned from inverted attitudes to upright attitudes while the legs remain inverted, thereby tending to rotate the thighs with respect to the backs, loosening the sockets between the thighs and backs, and the visceral cavities are placed on a rotary disk (28) formed of UHMW and having peripheral teeth with radially extending teeth surfaces which engage the backbone areas of the visceral cavities of the carcasses.

  • Patent number: 6315654
    Abstract: A tripes cleaning apparatus having a suspended, rotatable drum that presents an outer cylindrical surface on which the tripes are supported. The drum includes sets of flighting so as to facilitate arrangement of the tripes on each portion thereof in a single-layered helical orientation. A nozzle is associated with each set of flighting so that a low pressure cleaning fluid can be flushed through the tripes as the drum is rotated. Each nozzle is preferably activated to disperse cleaning fluid by bending the nozzle relative to its normally straight configuration, and a J-hook projects from the drum adjacent each nozzle to releasably hold the nozzle in the open, bent configuration and help retain the tripes against the drum. The apparatus further includes a spray bar operable to clean the outside of the tripes.

  • Patent number: 6309293
    Abstract: A method and a vacuum filler for filling a pasty filling material, in particular sausage meat, with the sausage meat being filled into a vane-type conveying mechanism by means of rotatably supported vane cells and a negative pressure being produced in a region of the vane-type conveying mechanism for supporting the intake of sausage meat into the vane-type conveying mechanism. The production of negative pressure is efficient in that it is substantially produced while the vane cells are rotating, which is made possible by installing a closure element for the at least partial opening and closing of a vacuum opening in the housing of the conveying mechanism.
