Vent cutter 240

Vent cutter 240

The Vent cutter 240 is the first of the three key machines in poultry evisceration, designed to process broilers, breeders, and layers. It cuts loose the vent (cloaca), bursa of Fabricius, and places it on the back of birds.


The Vent cutter 240 is placed in the overhead conveyor’s 240-degree curve, often as the first machine in the EV line, directly after the rehanger/hock cutter. Bled and defeathered birds hang in the overhead conveyor’s shackles and are guided into the infeed section of the machine, with the back of the birds towards the center of the machine.

Static infeed guides position the birds into the processing units of the vent cutter. The birds are held in position by the lower part of the processing unit - two-sided supports lift each bird and push it against a centering bracket, placed between the legs of the bird.

First, the bird is tilted into the correct position by the back support. Next, the drilling section of the processing unit is lowered onto the bird. The centering cone enters the vent, and then the knife starts drilling the first part of the skin around the vent. The bird is returned to a straight position before the unit is lowered. After cutting around the vent more deeply, a patented bushing mechanism inside the knife comes down and prevents the knife from cutting the intestines on the way further down/back up.

Finally, the bird is lowered again while the vent is still clamped in the drilling unit. This means that the intestines are pulled out over a length of about 100 mm. On release from the drilling unit, the vent is positioned over the back of the bird and the bird is released from the machine. After each cycle, the drill unit is cleaned at high pressure from the inside of the unit, ensuring a clean centering cone before each processing unit starts.


  • Intestinal damage reduced to absolute minimum, using patented inner bushing mechanism
  • Effective drill unit cleaning after each cycle, from inside of the unit
  • Exact and constant cutting results
  • No yield loss or back damage - due to exact drilling position and sophisticated bird handling
  • Large weight range within one machine setting
  • All adjustments adjustable during production (curve, back support, guides)
