Abstract

Methods and apparatuses for reducing food products. Such a method includes introducing a food product into an impeller rotating within a casing about an axis thereof. The impeller has paddles and pockets defined by and between adjacent pairs of the paddles. The paddles are circumferentially spaced so that each pocket is sequentially radially aligned with a circumferential opening of the casing as the impeller rotates. Each paddle has a relief slot defined in an outer radial edge of the paddle. Food products are expelled from the pockets and cut with a knife disposed at the circumferential opening of the casing as the impeller rotates and the pockets travel past the circumferential opening. The knife defines a cord of the casing, extends into the path of the paddles, and passes through the relief slots of the paddles.

First claim

The invention claimed is:

1. A method of reducing the size of food product, the method comprising:
rotating an impeller within a casing about an axis of the impeller, the impeller comprising a drum, paddles mounted to the drum, and pockets defined by and between adjacent pairs of the paddles, each of the paddles being associated with one of the pockets that is circumferentially ahead thereof in a direction of rotation of the impeller, the paddles being circumferentially spaced along a perimeter of the drum so that each pocket is sequentially radially aligned with a circumferential opening of the casing as the impeller rotates, each paddle having a relief slot defined in an outer radial edge of the paddle;
introducing a food product into the impeller;
pushing the food product with a surface of a first of the paddles associated with a first of the pockets;
expelling the food product from the first pocket;
cutting the food product with a knife disposed at the circumferential opening of the casing as the impeller rotates within the casing and the first pocket travels past the circumferential opening, the knife defining a cord of the casing and having a cutting edge located within an interior of the casing so that the knife extends into the path of the paddles; and
passing the knife through the relief slots of the paddles as the impeller rotates and the pockets pass across the circumferential opening.

2. The method according to claim 1 , wherein the surface of each paddle is approximately perpendicular to the cutting edge of the knife at the moment the paddle thereof has completed its pass across the circumferential opening of the casing.

3. The method according to claim 1 , wherein the surface of each paddle is approximately parallel to the knife at the moment a food product carried thereby encounters the knife.

4. The method according to claim 1 , wherein the knife is oriented perpendicular to the axis of the impeller.

5. The method according to claim 1 , wherein the knife is secured to the casing at oppositely-disposed ends of the knife.

6. The method according to claim 1 , wherein the knife makes a single cut through the food product.

7. The method according to claim 6 , wherein the knife halves the food product.

8. The method according to claim 1 , further comprising performing additional processing on the food product downstream of the knife.

9. The method according to claim 8 , wherein the additional processing comprises cutting the food product into strips or dicing the food product downstream of the knife.

10. A method of reducing the size of food product, the method comprising:
rotating an impeller within a casing about an axis of the impeller, the impeller comprising a drum, paddles mounted to the drum, and pockets defined by and between adjacent pairs of the paddles, each of the paddles being associated with one of the pockets that is circumferentially ahead thereof in a direction of rotation of the impeller, the paddles being circumferentially spaced along a perimeter of the drum so that each pocket is sequentially radially aligned with a circumferential opening of the casing as the impeller rotates, each paddle having a relief slot defined in an outer radial edge of the paddle;
introducing a food product into the impeller;
pushing the food product with a planar surface of a first of the paddles associated with a first of the pockets;
expelling the food product from the first pocket;
cutting the food product with a knife disposed at the circumferential opening of the casing as the impeller rotates within the casing and the first pocket travels past the circumferential opening, the knife defining a cord of the casing and having a cutting edge located within an interior of the casing so that the knife extends into the path of the paddles; and
passing the knife through the relief slots of the paddles as the impeller rotates and the pockets pass across the circumferential opening;
wherein the planar surface of each paddle is approximately perpendicular to the cutting edge of the knife at the moment the paddle thereof has completed its pass across the circumferential opening of the casing.

11. The method according to claim 10 , wherein the planar surface of each paddle is approximately parallel to the knife at the moment a food product carried thereby encounters the knife.

12. The method according to claim 10 , wherein the knife is oriented perpendicular to the axis of the impeller.

13. The method according to claim 10 , wherein the knife is secured to the casing at oppositely-disposed ends of the knife.

14. The method according to claim 10 , wherein the knife makes a single cut through the food product.

15. The method according to claim 14 , wherein the knife halves the food product.

16. The method according to claim 10 , further comprising performing additional processing on the food product downstream of the knife.

17. The method according to claim 16 , wherein the additional processing comprises cutting the food product into strips or dicing the food product downstream of the knife.
