The re-hanger transfers birds automatically from one processing line to the next, giving an in-line process for optimal tracking and tracing with no manual handling of the product required.Birds are transferred to an intermediate transport system, which conveys them to the other processing line.By putting a weighing unit in the intermediate transport system, it is possible to weigh individual birds. Weight information on each bird can then be passed to a PDS-NT control system for use in making choices on what is to happen to the bird in subsequent downstream processes.
