Method and moulding devices for moulding three-dimensional products
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 meat 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.
1. A mass feed member for feeding a meat mass to a mould cavity in an outer circumference of a drum of a moulding device, comprising:
a housing with an inlet side and a drum side which faces the drum, and walls;
a through-passage provided in the housing for the meat mass to pass from an inlet towards an outlet located on the drum side, the drum side being designed to adjust in a sealing manner to irregularities in the outer circumference of the drum;
a plate located at the drum side of the housing;
a plurality of radially movable lamellae movably supported between the walls of the housing, extending transversely with respect to the direction of rotation of the drum; and
one or more pressure cushions provided between an inner wall of the housing and the lamellae, wherein the lamellae are arranged between the pressure cushion and said plate, and wherein the plurality of lamellae and the one or more pressure cushions apply a pressure to said plate to flexibly bear against the outer circumference of the drum.
2. The mass feed member according to claim 1 , wherein the drum side of the mass feed member, as seen in the circumferential direction of the drum, extends on either side of the outlet, over a distance which covers at least one mould cavity.
3. The mass feed member according to claim 1 , wherein a cutting device is provided in the through-passage on the drum side.
4. The mass feed member according to claim 1 wherein a diverter passage is provided, which on one side is in communication with the through-passage and on the other side is in communication with an outlet opening at a position, upstream of the outlet of the through-passage, where the next mould cavity to be filled is located.
5. The mass feed member according to claim 1 , wherein the housing is of a virtually semicircular shape, with the through-passage extending in the radial direction.
6. The mass feed member according to claim 1 , wherein the walls of the housing are provided with openings extending in the radial direction, and wherein the radially movable lamellae are arranged between the openings in the walls of the housing.
7. The mass feed member according to claim 1 , wherein the walls of the housing comprise side walls, and the plurality of radially movable lamellae are movably supported between the side walls of the housing.
