Abstract

A molding device (10) for molding three-dimensional products (76) from a mass of foodstuff comprises a molding roller (16) and a filling device (18). The molding roller (16) has a molding surface with at least one mold cavity (44) which is delimited by a mold cavity (44) opening. The filling device (18) has a dispensing mouth (36) and a pump. The dispensing mouth (36) and the mold cavity (44) opening each have, viewed in the direction of the movement path, a front edge and a rear edge which is situated at a fixed distance thereof. A position-determining device determines the position of the front edge of the mold cavity (44) opening with respect to the front edge of the dispensing mouth during the movement of the mold cavity (44) opening and the dispensing mouth (36) with respect to each other. A control unit controls the pump on the basis of the position-determining device during the movement of the mold cavity (44) opening and the dispensing mouth (36) with respect to each other.

Claims

1. A moulding device for moulding three-dimensional products from a pumpable mass of foodstuff, comprising:

a mould member having a moulding surface in which at least one mould cavity for moulding the products from a mass of foodstuff is arranged, which said at least one mould cavity is provided with a mould cavity opening at the moulding surface and which said at least one mould cavity has a volume,

a filling device for filling the at least one mould cavity of the mould member with the mass of foodstuff, which filling device is provided with a dispensing mouth, and with a pump for displacing a volume of the mass of foodstuff from the dispensing mouth, wherein the mould cavity opening of the at least one mould cavity of the mould member and the dispensing mouth of the filling device are movable with respect to one another along a movement path,

a drive device to move the mould cavity opening of the at least one mould cavity of the mould member and the dispensing mouth of the filling device with respect to one another along said movement path,

wherein the dispensing mouth and the mould cavity opening each, viewed in a direction of said movement path, comprise a front edge and a rear edge which is situated at a fixed distance thereof, and wherein a distance between the front edge and the rear edge of the dispensing mouth in said direction of said movement path is smaller than a distance between the front edge and the rear edge of the mould cavity opening in said direction of said movement path, and wherein the moulding device further comprises;

a position-determining device for determining a position of the front edge of the mould cavity opening of the at least one mould cavity with respect to the front edge of the dispensing mouth of the filling device during movement of the mould cavity opening of the at least one mould cavity and the dispensing mouth of the filling device with respect to one another, and

a control unit which is connected to the position-determining device and to the pump, which said control unit being configured to control the pump;

(i) based on the position-determining device;

(ii) during the movement of the mould cavity opening of the at least one mould cavity and the dispensing mouth of the filling device with respect to one another;

(iii) in such a manner that the pump begins displacing a volume of the foodstuff, which substantially corresponds to the volume of the at least one mould cavity, from the dispensing mouth into the at least one mould cavity when the front edge of the mould cavity opening and the front edge of the dispensing mouth, viewed in the direction of said movement path, have moved past each other over a predetermined distance stored by the control unit such that the mould cavity opening and the dispensing mouth partly overlap each other at a mutual initial filling position; and

(iv) in such a manner that the pump stops displacing foodstuff from the dispensing mouth and into the at least one mould cavity when the front edge of the mould cavity opening and the front edge of the dispensing mouth, viewed in the direction of said movement path, have moved with respect to each other over a predetermined filling length stored by the control unit, wherein the predetermined filling length is smaller than the distance between the front edge and the rear edge of the mould cavity opening, viewed in the direction of said movement path.

2. Moulding device according to claim 1, wherein the moulding device further comprises a pressure sensor for detecting a pressure of the mass of the foodstuff in at least one of the at least one mould cavity and the dispensing mouth, and wherein the control unit is configured to control the pump on the basis of the position-determining device and the pressure sensor during the movement of the mould cavity opening of the at least one mould cavity and the dispensing mouth of the filling device with respect to each other in such a manner that, after the front edge of the mould cavity opening and the front edge of the dispensing mouth have been moved with respect to each other over the filling length and the pump has displaced the volume of the foodstuff which substantially corresponds to the volume of the at least one mould cavity from the dispensing mouth into the at least one mould cavity, the pump brings the foodstuff which is situated in the at least one mould cavity to a predetermined pressure which has been input into the control unit.

3. Moulding device according to claim 1, wherein the filling length is smaller than 50% or 40% or 30% of the distance between the front edge and the rear edge of the mould cavity opening, viewed in the direction of the movement path.

4. Moulding device according to claim 1, wherein the filling length is smaller than 20 mm.

5. Moulding device according to claim 1, wherein the dispensing mouth of the filling device is held in a substantially fixed position, and wherein the mould cavity opening is movable by the drive device along the movement path with respect to the dispensing mouth.

6. Moulding device according to claim 1, wherein the mould member comprises a moulding roller which is rotatable about an axis of rotation by said drive device, and wherein the moulding roller has a moulding roller peripheral wall which defines the moulding surface, and wherein the movement path is determined by a direction of rotation of the moulding roller about the axis of rotation.

7. Moulding device according to claim 1, wherein the at least one mould cavity comprises a bottom and a peripheral wall, and wherein the peripheral wall extends from the bottom and defines the mould cavity opening.

8. Moulding device according to claim 1, wherein the mould cavity opening of the at least one mould cavity has a substantially round shape.

9. Moulding device according to claim 1, wherein the mould cavity opening of the at least one mould cavity has a substantially oval shape, wherein the mould cavity opening has a length which extends in the direction of the movement path between the front edge and the rear edge of the mould cavity opening, and wherein the mould cavity opening has a width which extends in a direction transverse to the movement path, and wherein the length of the mould cavity opening is unequal to the width of the mould cavity opening.

10. Moulding device according to claim 1, wherein the filling device comprises an abutment surface in which the dispensing mouth is provided, and wherein the abutment surface sealingly abuts the moulding surface of the mould member during the movement of the mould cavity opening of the at least one mould cavity and the dispensing mouth of the filling device with respect to each other.
