The Meyn neck breaker removes necks to the highest accuracy and consistency. The possibility to adjust the neck length depending on end product requirements makes it possible to optimize yield. Even very short neck stumps (between the shoulders) are possible. The sideways clamping device avoids unnecessary neck skin damage and combined with the shoulder supports, wing damage is completely eliminated.
The necks fall directly in the receiving bin without touching the units or birds. This reduces the risk of cross contamination and keeps the machine clean allowing it to run without human interference. By simply changing the cam insert, the machine can also be used as a neck breaker that leaves the neck in the neck skin attached to the bird.
The neck breaker is placed in a 180 degrees curve of the overhead conveyor, as one of the final machines in the evisceration department. The bird is fed into the machine with its breast towards the unit. Sets of static and spring-loaded guides position the birds into the processing units. The birds are positioned by a centering bracket placed between the legs of the bird. The under unit consists of two shoulder supports, which lift each bird to eliminate the difference in bird size. At the same time, wings, broken or not, are lifted up and cannot be damaged or removed with the breaking unit. When the birds are positioned correctly, the curve controlled breaking unit breaks the neck. The length of the neck can be controlled with the height adjustment of the breaking unit.
After breaking the neck there are three possibilities with the standard machine:
Finally the neck, when removed from the carcass, is dropped onto the receiving bin. A rotating wiper removes the necks from the bin to be collected.
A cutting unit with a circular knife can be mounted onto the machine. The consequence is that the neck skin remains attached to the neck. A neck deskinner is required to clean the necks when clean necks can be sold.
