Apparatus and method for removing a surface layer from a food product
An apparatus for removing a surface layer from food products includes a product feed which feeds a product to be processed along a product conveying direction to a removal tool. The product is pressed with a component perpendicular to the product conveying direction toward an operative surface of the removal tool. The relative position between the product feed and the removal tool is adjustable by means of an adjustment apparatus, with a control unit associated with the adjustment apparatus designed to adjust the position of the removal tool relative to the product feed in dependence on the contour of the product.
1. An apparatus for removing a surface layer from food products comprising:
a product feed which feeds a product to be processed along a product conveying direction to a removal tool, such that the product is pressed with a component perpendicular to the product conveying direction toward an operative surface of the removal tool; and
an adjustment apparatus for adjusting the relative position between the product feed and the removal tool, there being a control unit associated with the adjustment apparatus, the control unit being designed to adjust the relative position between the product feed and the removal tool in dependence on a contour of the product.
2. The apparatus of claim 1 , wherein a relative position between a counter-surface of the product feed and the removal tool is adjustable.
3. The apparatus of claim 2 , wherein the counter-surface is formed at a pressing apparatus.
4. The apparatus of claim 3 , wherein the pressing apparatus includes a pressing roller.
5. The apparatus of claim 1 , wherein a relative position between a pressing apparatus and a product support surface of the product feed is adjustable.
6. The apparatus of claim 5 , wherein the product support surface inclues one of a cut-out portion and a recess portion and the removal tool is arranged in the one of a cut-out portion and a recess portion.
7. The apparatus of claim 1 , wherein the product feed includes a pressing apparatus designed to press the product toward a product support surface of the product feed.
8. The apparatus of claim 7 , wherein the removal tool being arranged in one of a cut-out portion and a recess portion of the product support surface.
9. The apparatus of claim 1 , wherein the removal tool is arranged in a fixed position with respect to an adjustment direction relative to a product support surface of the product feed.
10. The apparatus of claim 1 , wherein the control unit is designed to continuously adjust a counter surface of the product feed to follow a contour of the product during the removal procedure.
11. The apparatus of claim 1 , wherein a detection device is connected to the control unit.
12. The apparatus of claim 11 , wherein the detection device operates in a contact-free manner for determining the contour of the product.
13. The apparatus of claim 11 , wherein the detection device includes at least one distance measuring sensor.
14. The apparatus of claim 13 , wherein said distance measuring sensor is an ultrasound-based sensor.
15. The apparatus of claim 1 , wherein the removal tool includes a tool for at least one of defatting, skinning and derinding said product.
16. The apparatus of claim 1 , wherein the removal tool includes at least one roller rotatable about an axis of rotation extending transversely to the product conveying direction.
17. The apparatus of claim 1 , wherein the removal tool includes at least one of a knife and a blade.
18. The apparatus of claim 1 , wherein a conveying device is situated in front of the knife or of the blade when viewed in the product conveying direction.
19. The apparatus of claim 18 , wherein said conveying device is formed as a roller.
20. The apparatus of claim 1 , wherein the adjustment apparatus includes a motorized actuating drive.
21. The apparatus of claim 20 , wherein the motorized actuating drive includes a controllable electric motor.
22. The apparatus of claim 1 , wherein a pressing apparatus of the product feed is attached to a pivot arm, with the pressing apparatus being able to be raised and lowered with respect to a product support surface of the product feed by a pivoting of the pivot arm with the adjustment apparatus.
23. The apparatus of claim 1 , wherein the adjustment apparatus is additionally designed to adjust the relative position between the product feed and the removal tool in dependence on a quality of the product.
24. A method for removing a surface layer from food products comprising:
determining a contour of a product to be processed;
feeding the product along a product conveying direction to a removal tool such that the product is pressed with a component perpendicular to the product conveying direction toward an operative surface of the removal tool; and
adjusting the relative position between a product feed, and the removal tool by an adjustment apparatus in dependence on the determined contour of the product.
25. The method of claim 24 , wherein said product feed comprises a pressing apparatus and the method includes the step of adjusting the relative position between the pressing apparatus and the removal tool.
26. The method of claim 24 , wherein the position of a pressing apparatus of the product feed is adjusted to follow the contour of the product during the removal procedure.
27. The method of claim 24 , wherein the contour of the total product is determined before a start of the removal procedure.
28. The method of claim 24 , wherein the contour of the product is determined one of point-wise and section-wise during the removal procedure.
