Method for the production of three-dimensional products from a mass of pumpable fibrous foodstuff material, for example from ground meat, wherein the mass of pumpable fibrous foodstuff material is fed by a foodstuff mass feed and pressurization assembly into a chamber (30;230) via an inlet (31;231) thereof, wherein a perforated plate (40;240) is stationary arranged at an outlet side of the chamber (30;230), which perforated plate has a multitude of perforations therein between an inlet face of the perforated plate directed towards said chamber and an opposed outlet face of the perforated plate, wherein a flow channels assembly (50;250) connects to the outlet side of the chamber, which flow channels assembly comprises multiple flow channels (53,54,55: 253, 254,255, 256), each flow channel having a flow channel inlet opening, a flow channel discharge mouth (61,62,63; 261,262,263,264), and a flow channel length, wherein the flow channel inlet openings are stationary arranged adjoining the outlet face of the perforated plate (40;240), so that each flow channel receives therein strands of fibrous foodstuff material emerging at the outlet face of the perforated plate from a subset of the multitude of perforations in the perforated plate, wherein the strands that are introduced into a flow channel merge into a coherent bundle (501,502,503,504), in which the strands are arranged against one another in a generally parallel orientation, wherein said bundle is confined within the flow channel and passes through the flow channel to the discharge mouth (61,62,63; 261,262,263,264) where the bundle is discharged, whilst maintaining the generally parallel orientation of the strands in the bundle, wherein a production device (100, 300, 800, 1100) is arranged at the discharge mouths of the flow channels assembly, which production device is configured and operated to produce three-dimensional products, each product out of a portion of a bundle that is discharged from one of the discharge mouths. wherein the mass of pumpable fibrous foodstuff material is fed by a foodstuff mass feed and pressurization assembly into a chamber (30;230) via an inlet (31;231) thereof, wherein a perforated plate (40;240) is stationary arranged at an outlet side of the chamber (30;230), which perforated plate has a multitude of perforations therein between an inlet face of the perforated plate directed towards said chamber and an opposed outlet face of the perforated plate, wherein a flow channels assembly (50;250) connects to the outlet side of the chamber, which flow channels assembly comprises multiple flow channels (53,54,55: 253, 254,255, 256), each flow channel having a flow channel inlet opening, a flow channel discharge mouth (61,62,63; 261,262,263,264), and a flow channel length, wherein the flow channel inlet openings are stationary arranged adjoining the outlet face of the perforated plate (40;240), so that each flow channel receives therein strands of fibrous foodstuff material emerging at the outlet face of the perforated plate from a subset of the multitude of perforations in the perforated plate, wherein the strands that are introduced into a flow channel merge into a coherent bundle (501,502,503,504), in which the strands are arranged against one another in a generally parallel orientation, wherein said bundle is confined within the flow channel and passes through the flow channel to the discharge mouth (61,62,63; 261,262,263,264) where the bundle is discharged, whilst maintaining the generally parallel orientation of the strands in the bundle, wherein a production device (100, 300, 800, 1100) is arranged at the discharge mouths of the flow channels assembly, which production device is configured and operated to produce three-dimensional products, each product out of a portion of a bundle that is discharged from one of the discharge mouths.
