Method and moulding devices for moulding three-dimensional products

摘要

The invention provides a method for molding three-dimensional products from a mass of foodstuff starting materials which are suitable for consumption, in particular a meal mass. The method comprises the steps of filling a mold cavity, which is open on one side, with the mass of foodstuff starting materials which are suitable for consumption, which mold cavity is defined by a boundary comprising walls and base, in order to mold a molded three-dimensional product, and the removal of the molded three-dimensional product from the mold cavity. In the method according to the invention, during removal the adhesion forces between the molded product and the boundary are eliminated virtually simultaneously along all the interfaces.

主权项

1. 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 said 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 device, arranged between the drum side of the housing and the flexible plate over a distance which essentially covers said flexible plate, said excess-pressure device 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.
