A continuous method and system for processing whole muscle meat employs a mixer housing having a pair of parallel rotating shafts located therein. The parallel rotating shafts have a plurality of mixing elements thereon, such as frustoconical elements, blocking elements, or ellipsoid elements. The mixer housing has an input end to receive the meat ingredients, such as meat pieces, salt solution, water, preservatives, and other additives such as spices. The mixer housing has an output, which is separated a distance from the input, such that the output discharges the whole muscle meat product. As the ingredients including the meat move from the input to the output along the shafts, the mixing elements work the meat with the other ingredients thereby increasing ingredient incorporation including diffusion of the salt solution into the whole muscle meat pieces.
