For processors in many countries of the world feet are a profitable by-product. It is, however, imperative that the feet processing system handles only 'A' grade material. Local regulations can forbid the processing of downgraded feet together with feet fit for human consumption.
Selective unloading technology is needed to remove rejected feet before entering the feet scalding process. The Marel Selective Foot Unloader does precisely this. It takes information from a veterinary inspection station and automatically unshackles every single downgraded foot in an unloading carrousel.
Rejection by veterinarian
Suppose the veterinarian station rejects a carcass. Sensors and tracing software allow for so-called ‘paw tracking’. The system registers the shackle from which the carcass has been removed and locates the corresponding shackle with feet. The Selective Foot Unloader then receives a signal via Innova PDS to remove both feet - and those two feet only - that belong to the rejected carcass from this shackle.
