Birds enter the device with their backs towards the inside of the machine.
The device is of carousel type, driven by the overhead conveyor. The cutter assembly, fitted with an exceptionally sharp blade, provides a uniform and clean cut.
The blade holder is designed so that the viscera are pushed away from the cutline, which prevents infection.
After every turn, the cutting heads are washed and cleaned.
