process and apparatus for the manufacture of modeled meat portions of whole pieces of natural meat. The invention relates to a process for the manufacture of modeled meat portions of whole meat pieces with the following process steps: introduction of the pieces into a processing line, selection of meat pieces, the weight of which should be less than a theoretical weight. , cutting of meat pieces, the weight of which should be greater than a theoretical weight, and selection of meat pieces, the weight of which will correspond to a theoretical weight, freezing the selected meat pieces in meat portions and in meat portion shapes by placing them in a cavity for molded portions of meat and pressing or pressing and cutting them into that cavity. The disadvantage of known processes is that there will not be many serviceable portions in the process if the portion (s) are produced from only one part. This disadvantage is mitigated by the invention by the fact that weight control and shape control are performed in separate partial processes. In this case substantially less constraints arise with respect to the shape of the meat portions in weight control and / or significantly greater flexibility in the construction of the final three-dimensional shape than in known processes.processo e dispositivo para a fabricaçao de porções de carne modeladas de peças inteiras de carne natural. a invenção se refere a um processo para a fabricação de porções de carne modeladas de peças de carne inteiras com as seguintes fases processuais: introdução das peças em uma linha de processamento, seleção das peças de carne, cujo peso deverá ser inferior a um peso teórico, corte das peças de carne, cujo peso deverá ser superior a um peso teórico, e seleção das peças de carne, cujo peso corresponderá a um peso teórico, congelamento das peças de carne selecionadas em porções de carne e em formas das porções de carne colocando-as em uma cavidade para porções de carne moldadas e prensando-as ou prensan
