Post eviscerator operations

Perfect product preparation before chilling

  • Optimal carcass preparation for chilling
  • Highly hygienic operations at all stages
  • Careful handling of the neck and neck skin
  • High-yield harvesting of necks and tongues


After the eviscerator, several operations have to be done to prepare the products optimally for chilling and achieve the highest yield for the main product as well as by-products.

In the duck industry, careful handling of the neck and neck skin is crucial for the end product. Marel PMJ uses four machines to ensure the best possible effective neck process: Neck Skin Slitter, Head Cutter & Tongue Harvester, Neck Skin Inspection Machine and Neck Cracker. Performance of this four-stage neck process is independent of the killing method used after stunning. The combined system performs better than any other when it comes to the removal of esophagus and trachea. All neck processes aim to get a higher neck skin yield and better neck skin presentation.

Neck Skin Slitter

Marel PMJ's Neck Skin Slitter cuts the skin of the neck lengthwise. This neck slit is done very accurately at the back of the neck. The opening created allows easy removal of the neck bone by the Neck Breaker system.

Head Cutter & Tongue Harvester

Marel PMJ's Head Cutter & Tongue Harvester harvests the tongue automatically by cutting the beak. The beak including the tongue is discharged separately. This allows for a high yield of tongue products. In the next step, the head is severed from the neck automatically and also discharged separately. The head removal is done in a way to enable high-yield neck harvesting in a later stage. 

Neck Skin Cleaner

The Neck Skin Cleaner, also known as 'Cropper' removes the esophagus (food pipe) or its remnants and the trachea (windpipe) from the area in between the neck and neck skin. This is done very effectively to ensure a high-quality neck skin. During the cleaning action, the rotating movement stops, which results in an extended brush life. 

Neck Breaker

The Neck Breaker removes the neck bone from the product. Optionally, the neck bone can be cracked in the middle for easier and compact giblet packing. Pulling the bone before breaking results in high neck bone yield, that is a longer neck bone. 
Only the neck bone is removed; the cleaned neck skin stays with the product. 

Final Inspection Machine

A final carcass check is done by the Final Inspection Machine. It uses vacuum to remove the (remnants of) lungs and other debris from the rib cage area inside. The double-barrel probe allows for independent vacuum cleaning of the left and right cage, assuring an optimal cleaning result. The gentle shape of the tip prevents rib cage damage while applying thorough cleaning. The Final Inspection Machine operates very energy-efficiently, as vacuum is only active when the probes are in cleaning position.

Inside Outside Washer

Commonly the final step of the evisceration process is inside and outside cleaning of the carcass. Marel PMJ's Inside Outside Washer does its task thoroughly with low water use. This is made possible by the sophisticated nozzle design and nozzle positioning as well as the optional air/water mixture system.
