Giraffes, screws and buffers

Transport and buffering

  • Transports both fresh and frozen minced meat
  • Meets the strictest hygiene requirements, easy to clean
  • Robust, heavy duty system


Marel giraffes, screw conveyors and buffers are suitable for transport / buffering of both fresh and frozen minced meat.

Optionally, the outlets can be equipped with a pneumatic retractable chute system. For safety reasons, the Giraffes are equipped with a "grill" safety cover over the horizontal screw. Doors, which can be opened, are mounted with safety switches.

The robust machine housing is made in heavy duty AISI 304 stainless steel and designed without corners or edges in order to facilitate cleaning. Likewise, easy dismount of horizontal screw and quick opening of vertical / inclined screw makes cleaning easier. Thus the equipment meets the strictest hygiene requirements.

The machines can be standalone, or be part of an integrated processing line. Since the electric control unit is mounted on the machine, it is only a matter of plugging it in.
