Abstract

A system for forming a product. The system includes a hopper with a rotating feeder; a mold drum with cavities; and a feed pump with a moving member. The feed pump is configured to pump food mass from the hopper into the cavities. The system has means configured to determine: a position and a motion of the mold drum relative to a frame of the system; a position and a motion of the moving member of the feed pump relative to a housing of the feed pump; and a position and a motion of the rotating feeder relative to the hopper to synchronize the motion of the mold drum and the motion of the moving member of the feed pump and to synchronize the motion of the rotating feeder with the motion of the moving member of the feed pump. The system has at least two pressure sensors.

First claim

What is claimed is:

1. A system for forming a product from a food mass, the system comprising:
a hopper with a rotating feeder;
a mould drum comprising cavities to form products, the cavities are at least partially made from a porous material; and
a feed pump with a moving member, the feed pump is configured to pump the food mass from the hopper into the cavities;
wherein the system comprises means configured to determine:
i) a position and a motion of the mould drum relative to a frame of the system; and
ii) a position and a motion of the moving member of the feed pump relative to a housing of the feed pump; and
iii) a position and a motion of the rotating feeder relative to the hopper to synchronize the motion of the mould drum and the motion of the moving member of the feed pump and to synchronize the motion of the rotating feeder with the motion of the moving member of the feed pump,

wherein the feed pump is connected to a vacuum source, and
wherein the system comprises at least two pressure sensors that are arranged between the feed pump and the mould drum, the at least two pressure sensors are configured to determine a pressure distribution over an axial length of the mould drum and over an axial length of an outlet of the feed pump.

2. The system for forming a product from a food mass according to claim 1 , wherein the feed pump is a positive displacement pump with a rotor, and
wherein an axis of rotation of the rotor is in parallel to an axis of rotation of the mould drum.

3. The system for forming a product from a food mass according to claim 1 , wherein the feed pump is a vane pump comprising a compression zone and a transport zone, the compression zone is configured to compress the food mass to a desired feed pressure, the vane pump comprising vanes, and
wherein in both the compression zone and the transport zone, and at an outlet of the feed pump, tips of the vanes are free from touching the housing of the feed pump.

4. The system for forming a product from a food mass according to claim 1 , wherein the system comprises a divider located between the feed pump and the mould drum, the divider is directly connected to the housing of the feed pump or integral with the housing of the feed pump.

5. The system for forming a product from a food mass according to claim 1 , wherein an axial length of a rotor of the feed pump is generally equal to an axial length of the mould drum.

6. The system according to claim 1 , wherein each of the cavities are connected to a fluid passage that extends parallel to an axis of rotation of the mould drum.

7. The system according to claim 2 , wherein the positive displacement pump is a portioning device, the portioning device is configured to feed food mass towards the mould member to fill one of the cavities or a row of the cavities, and
wherein a speed of rotation of the rotor is reduced during filling of the cavities or the rows of the cavities.

8. The system according to claim 1 , wherein the mould drum comprises at least one sensor, and
wherein a discharge of formed products from the cavities is controlled according to a signal from the at least one sensor.

9. A system for forming a product from a food mass, comprising:
a hopper with a rotating feeder;
a mould drum; and
a feed pump with a moving member;
wherein the mould drum comprises cavities to form products;
wherein the cavities are at least partially made from a porous material;
wherein to synchronize a motion of the mould drum and a motion of the moving member of the feed pump, the system comprises means configured to determine:
i) a position and the motion of the mould drum relative to a frame of the system; and
ii) a position and the motion of the moving member relative to a housing of the feed pump,

wherein the feed pump is connected to a vacuum source that is configured to apply vacuum to the feed pump prior to an inlet of the food mass, the vacuum source is provided within the housing of the feed pump,
wherein the feed pump is a positive displacement pump with a rotor,
wherein an axis of rotation of the rotor is in parallel to an axis of rotation of the mould drum,
wherein the positive displacement pump is a portioning device, the portioning device is configured to feed the food mass towards the mould drum to fill one of the cavities or a row of the cavities, a speed of rotation of the rotor is reduced during filling of the cavities, and
wherein the system comprises at least two pressure sensors that are arranged between the feed pump and the mold drum, the at least two pressure sensors are configured to determine a pressure distribution over an axial length of the mould drum and over an axial length of an outlet of the feed pump.

10. The system according to claim 9 , wherein the means is configured to determine:
a position and a motion of the rotating feeder relative to the hopper.
