Abstract: A system and a method for moulding food products from a pumpable foodstuff mass include a mould member having an outer surface. One or more recessed mould cavities are provided. An ejection fluid inlet opening of the mould member is arranged relatively movable with respect to an outlet opening of the ejection fluid source. Ejection fluid is allowed to enter the mould member when an outlet opening overlaps an ejection fluid inlet opening.

Abstract: A mould drum, a system for moulding comprising a mould drum, a method for moulding, and a method for manufacturing a mould drum such that the mould drum includes a mould tube defining an outer circumferential surface with groups of multiple recessed mould cavities. The mould tube has a first mould tube head end. The mould drum includes 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. 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.
