ABSTRACT:
A meat processing system and method wherein trim pieces of meat having lean meat portions and fat meat portions are divided into smaller regular sized meat chunks of higher lean meat content and chunks of higher fat content. The chunks are passed seriatim through a photometric sensing zone to photometrically detect an optical property related to the lean meat or fat content of the meat chunks and the meat chunks are thereafter sorted in accordance with the value of the optical property sensed in the photometric sensing zone. Meat chunks of higher lean meat content are thereby sorted from chunks of higher fat content. The temperature of the meat chunks is maintained at or near the freezing temperature to facilitate singularizing and handling of the meat chunks so that the meat chunks can be passed seriatim through the photometric sensing zone.
