Smooth multiphase process for optimal animal welfare

Broilers on the belt or in their SmartStack trays are transferred smoothly to the CAS SmoothFlow system. These straight movements — without sudden transitions — makes for one of the most humane processes in the industry.

Product quality guaranteed

Controlled atmosphere anesthetization is not only humane, but it ensures the highest possible meat quality. Blood spots or fractures are kept to a minimum, considerably reducing downgrades. The smooth movements without human intervention ensure the supplied quality. The first-in-first-out principle keeps track of the consistency of this high quality.
