Abstract

A conveyor belt system that provides a continuous flat support surface for a food item that grips the food item when compressed against a reactive surface. The conveyor belt system comprises a conveyor belt and a reactive surface, the conveyor belt having a top side and a bottom side, the top side being parallel to the reactive surface and facing the reactive surface. The conveyor belt further comprises a plurality of spaced rods and a plurality of flat metal slats, each slat having a leading edge and a trailing edge relative to a direction of conveyance travel of the conveyor belt, the leading edge of the slat coupled to one of the plurality of rods to provide a hinged joint at the leading edge of the slat.

Claims

1. A conveyor belt system for compressing a food product, comprising:

a conveyor belt and an opposing reactive surface, the conveyor belt having a top side and a bottom side, the top side being substantially parallel to and facing the reactive surface;

the conveyor belt further comprising a plurality of spaced rods and a plurality of substantially flat metal slats, the slats comprising a base portion having a leading edge and a trailing edge relative to a direction of conveyance travel of the conveyor belt, the leading edge being coupled to one of the plurality of rods and the trailing edge being free of attachment, so as to provide a hinged joint arranged to provide at least partial rotation at the leading edge of each slat.

2. The conveyor belt system according to claim 1, wherein the slats are coupled to a first spaced rod and extend over at least a second spaced rod, the second spaced rod being immediately adjacent to the first spaced rod.

3. The conveyor belt system according to claim 2, wherein the slats extend over the first spaced rod and the second spaced rod, wherein the slats substantially abut without contacting a third spaced rod, the third spaced rod being immediately adjacent to the second spaced rod.

4. The conveyor belt system according to claim 1, wherein the slats comprise at least one channel portion at the leading edge, the channel portion capable of receiving one of the plurality of rods and permitting at least partial rotation of the slat.

5. The conveyor belt system according to claim 1, wherein the slats comprise multiple channel portions protruding from the leading edge, each channel portion comprising a u-shaped hook member.

6. The conveyor belt system according to claim 5, wherein the slats comprise multiple notches along the trailing edge, the notches being disposed in positions along the trailing edge that correspond to the positions of the channel portions protruding from the leading edge.

7. The conveyor belt system according to claim 1, wherein the plurality of spaced rods are provided by a wire conveyor belt scaffolding.

8. The conveyor belt system according to claim 1, wherein the slats comprise a material selected from the group consisting of metals, plastics, and ceramics.

9. The conveyor belt system according to claim 1, wherein the plurality of metal slats create a substantially flat support surface for conveying a food item at the top side of the conveyor belt.

10. The conveyor belt system according to claim 1, wherein the conveyor belt system is arranged for the conveyor belt to run in a substantially horizontal direction and each slat hangs vertically from the hinged joint at a bottom return side of the conveyor belt, the bottom return side of the conveyor belt traveling in a direction opposite the direction of conveyance.

11. The conveyor belt system according to claim 1, wherein each slat has a length along the direction of conveyance that is greater than a distance between two immediately adjacent spaced rods.

12. The conveyor belt system according to claim 1, wherein a top conveyance side of the conveyor belt system is adapted to compress the food product against the reactive surface.

13. The conveyor belt system according to claim 1, wherein the reactive surface is a heated platen for heating the food product or a second conveyor belt.

14. The conveyor belt system according to claim 1, wherein the trailing edge of each slat comprises a bent portion, the bent portion comprising an arm extending at an acute angle relative to an axis defined by the base portion.

15. A food heating device comprising:

a conveyor belt and at least one platen for heating food products, the conveyor belt comprising a top side and a bottom side, the top side being substantially parallel to and facing the platen;

the conveyor belt further comprising a plurality of spaced rods and a plurality of substantially flat metal slats, the slats comprising a base portion having a leading edge and a trailing edge relative to a direction of conveyance travel of the conveyor belt, the leading edge being coupled to one of the plurality of rods and the trailing edge being free of attachment, so as to provide a hinged joint arranged to provide partial rotation at the leading edge of each slat;

wherein the conveyor belt is configured to compress the food product against the at least one platen while moving relative to the at least one platen.

16. The conveyor belt system according to claim 15, wherein the slats couple to a first spaced rod and extend over at least a second spaced rod, the second spaced rod being immediately adjacent to the first spaced rod.

17. The conveyor belt system according to claim 16, wherein the slats extend over the first spaced rod and the second spaced rod, wherein the slats substantially abut without contacting a third spaced rod, the third spaced rod being immediately adjacent to the second spaced rod.

18. The conveyor belt system according to claim 15, wherein the slats comprise at least one channel portion at the leading edge, the channel portion capable of receiving one of the plurality of rods and permitting at least partial rotation of the slat (around an axis defined by the respective rod).

19. The conveyor belt system according to claim 15, wherein the slats comprise multiple channel portions protruding from the leading edge, each channel portion comprising a u-shaped hook member.

20. The conveyor belt system according to claim 19, wherein the slats comprise multiple notches along the trailing edge, the notches being disposed in positions along the trailing edge that correspond to the positions of the channel portions protruding from the leading edge.
