When Meyn developed its new multistage CO2 stunning system, a co-development with Praxair Inc., a lot of attention was given to animal welfare. As the birds remain in the drawer or container during stunning, the handling and transport of active birds is completely eliminated. This largely reduces handling stress and thus risk on injuries to the birds. The closed cabinet construction allows for the CO2 concentration to be managed perfectly in every stage of the process. This ensures a humane stun and greatly improves product quality.
The Meyn multistage CO2 stunning system forms an integral part of the Meyn live bird handling systems. Both new as well as existing configurations can be extended with this innovative stunning system.
A configuration of container conveyors including a shuttle track supplies containers to the stunning cabinets fully automatically. Depending on container load and line capacity the system comprises one to four stunning cabinets, each of which can hold either a single or a stack of two containers. Once inside the stunning cabinet, the CO2 stunning sequence is started and the multistage process is carefully executed, ensuring a humane but irreversible stun. Upon completion of the stun cycle, the containers are automatically transported, destacked and unloaded. The Meyn system suits all relevant container types including drawer system modules.
