The Alberk Automatic Vent Opener is designed to provide controlled access to the abdominal cavity following the vent cutting process, preparing the poultry carcass for the subsequent automatic evisceration stage. As carcasses travel suspended from shackles, the positioning cradle and back guides accurately direct each bird into the cutting unit, enabling a consistent and repeatable opening process throughout continuous production. The cutting mechanism performs a controlled incision from the vent area, creating the required opening for efficient removal of the internal organs during the following evisceration process. Accurate carcass positioning and controlled incision length help minimize unintended contact with internal organs and reduce unnecessary cuts to the carcass, supporting consistent processing quality. The multi-station design operates in synchronization with the overhead conveyor to provide continuous, controlled, and reliable performance at high processing capacities. Machine height and operating position can be adjusted according to different carcass sizes, while the integrated automatic washing system helps keep the processing units clean during operation and supports effective hygiene control throughout the poultry evisceration line.
