Abstract

It is disclosed an industrial slicer of a food product. The slicer comprises means for guiding and conveying the food product along a conveying direction, comprises means for pressing the food product against the guiding and conveying means, wherein the minimum distance between the pressing means and the guiding and conveying means is configurable, comprises means for cutting the food product into a plurality of pieces according to a configured cutting pitch, comprises pre-pressing means for exerting a pressure value on the food product and comprises a control unit. The control unit is configured to calculate a number of cutting pieces. The cutting means are configured to cut the pressed food product into a number of pieces equal to the calculated number of cutting pieces.

Claims

1. Industrial slicer of a food product, the slicer comprising:

means for guiding and conveying the food product along a conveying direction;

means for pressing the food product against the guiding and conveying means, wherein the minimum distance between the pressing means and the guiding and conveying means is configurable;

means for cutting the food product into a plurality of pieces according to a configured cutting pitch;

pre-pressing means for exerting a pressure value on the food product;

a control unit configured to;

calculate a dimension of the pressed food product;

calculate, as a function of the dimension of the food product and of a configured cutting pitch, a number of cutting pieces;

calculate, as a function of the calculated number of cutting pieces and of the configured cutting pitch, a cutting dimension of the food product;

set the value for the minimum distance between the pressing means and the guiding and conveying means equal to the value of the cutting dimension

control the movement of the guiding arid conveying means in order to convey the food product pressing it through the minimum distance equal to the value of the cutting dimension;

wherein the cutting means are configured to cut the pressed food product into a number of pieces equal to the calculated number of cutting pieces.

2. Industrial slicer according to claim 1, wherein the control unit is configured to calculate the number of cutting pieces by dividing the calculated dimension of the food product by the configured cutting pitch and rounding the result of the division up or down to the preceding or following integer number,

and wherein the control unit is configured to calculate the cutting dimension by multiplying the rounded result of the division by the configured cutting pitch.

3. Industrial slicer according to claim 1, wherein the guiding and conveying means are a conveyor belt and the pressing means are a pressing belt having a length shorter than the length of the conveyor belt,

wherein the pre-pressing means comprises:

a rotating roller having a peripheral velocity substantially equal to that of the conveyor belt and being oscillating with respect to the surface of the conveyor belt;

at least one arm for connecting the rotating roller to a portion of the frame;

wherein the control unit is configured to;

detect the angle defined by at least one arm when the food product passes under the rotating roller;

calculate, as a function of the detected angle, the value of the minimum distance between the conveyor belt and the pressing belt.

4. Industrial slicer according to claim 2, wherein the guiding and conveying means are a conveyor belt and the pressing means are a pressing belt having a length shorter than the length of the conveyor belt,

wherein the pre-pressing means comprises:

a rotating roller having a peripheral velocity substantially equal to that of the conveyor belt and being oscillating with respect to the surface of the conveyor belt;

at least one arm for connecting the rotating roller to a portion of the frame;

wherein the control unit is configured to;

detect the angle defined by at least one arm when the food product passes under the rotating roller;

calculate, as a function of the detected angle, the value of the minimum distance between the conveyor belt and the pressing belt.

5. Industrial slicer according to claim 2, wherein the cutting means have a cutting plane that is substantially parallel to the conveying direction and have a cutting movement in a direction that is substantially perpendicular to the conveying direction,

wherein the dimension of the food product is the height of the food product with respect to the plane defined by the guiding and conveying means,

and wherein the direction of the minimum distance is substantially perpendicular to the plane defined by the guiding and conveying means.

6. Industrial slicer according to claim 1, wherein the dimension of the food product is the maxim dimension of the food product, in particular the maximum height.

7. Industrial slicer according to claim 3, further comprising a guiding plate interposed between the pressing belt and the cutting means, configured to keep the food product pressed during the cutting process.

8. Method for cutting a food product into a plurality of pieces, comprising the steps of:

conveying the food product over means for guiding and conveying the food product along a conveying direction;

b) exerting a pressure value on the food product and calculating a dimension of the pressed food product;

c) calculating, as a function of the dimension of the food product and of a configured cutting pitch, a number of cutting pieces;

d) calculating, as a function of the calculated number of cutting pieces arid of the configured cutting pitch, a cutting dimension for the food product;

e) conveying the food product over the guiding and conveying means and pressing it through an opening having a dimension equal to the cutting dimension;

f) cutting the pressed food product into a number of pieces equal to the calculated number of cutting pieces.

9. Method according to claim 8, wherein in step c) the number of cutting pieces is calculated by dividing the dimension of the food product by the configured cutting pitch and rounding the result of the division up or down to the preceding or following integer number, and wherein in step d) the cutting dimension is calculated by multiplying the rounded result of the division by the configured cutting pitch.

10. Method according to claim 9, wherein the dimension of the food product is the maximum dimension of the food product.

11. Method according to claim 9, wherein the dimension of the food product is the maximum height of the food product with respect to the plane defined by the guiding and conveying means.

14. Computer readable medium having a program recorded threreon, said computer readable medium comprising computer code means adapted to perform the calculation of step b) and the steps c), d) of the method according to claim 8, when said program is run on a computer.

12. Method according to clam 11, wherein in step e) said dimension (H1z) has a direction which is substantially perpendicular to the plane (XY) defined by the guiding and conveying means.

13. Method according to claim 12, wherein in step f) said cutting is performed in a cutting plane (Pt) which is substantially parallel to the conveying direction (X) and which has a cutting movement in a direction (Y) that is substantially perpendicular to the conveying direction (X).
