Method and moulding devices for moulding three-dimensional products

A moulding device for moulding three-dimensional products from a meat mass suitable for consumption, comprising:

• a rotatable moulding drum having a longitudinal axis and axial ends, said drum comprising:
• a cylindrical drum wall having an outer peripheral cylindrical surface,
• multiple mould cavities formed in the outer peripheral surface of the drum wall, which mould cavities define the shape of the products which are to be produced, the mould cavities being open on one side and defined by a boundary comprising walls and base,
• a drum drive, adapted to rotate the rum in a direction of rotation about the longitudinal axis thereof,
• a mass feed member arranged at a mass feed position along the outer peripheral cylindrical surface of the moulding drum and adapted to feed said mass to passing mould cavities, which mass feed member comprises:
• a housing with an inlet side and a drum side which faces the drum,
• a through-passage provided in the housing for the mass of foodstuff to pass from an inlet towards an outlet located on the drum side,
• a flexible plate located at the drum side of the housing in which the outlet to a mould cavity is provided, extending on either side of the outlet over a distance which covers at least one mould cavity,
• a pressure medium operated excess-pressure means, arranged between the drum side of the housing and the flexible plate over a distance which essentially covers said flexible plate, said excess-pressure means being adapted to apply a pressure onto said flexible plate to flexibly bear the plate in sealing engagement against the outer peripheral cylindrical surface of the drum, to adjust in a sealing manner to irregularities in the outer peripheral cylindrical surface of the drum.
