Mould drum, system and method for moulding and a method for configuring a mould drum

A mould drum configured for use in a system for moulding food products from a pumpable foodstuff mass, the mould drum comprising:

• a mould tube made of porous material, the mould tube defining an outer circumferential surface wherein groups of multiple recessed mould cavities are provided, the mould tube having a first and second mould tube head end;
• a driven flange structure arranged against the first mould tube head end, which is adapted to be driven by a mould drum drive member to rotate the mould tube about a drum rotation axis;
• wherein the driven flange structure is provided with a tooth profile, and the mould tube is provided with a meshing tooth profile, both tooth profiles meshing with each other and thereby being able to transfer torque from the driven flange structure to the mould tube wherein the meshing tooth profile provided in the mould tube is formed by a series of recesses made in the porous material of the mould tube, provided in an inner tube surface opposite the outer circumferential surface, and being concealed by the outer circumferential surface.
