This invention relates to a food processing apparatus, and in particular to an apparatus for cutting foodstuff into predetermined shapes and sizes.
It is often desirable to shape or size items of food in order that they are more easily consumed, more palatable, can be processed more easily, or are just more aesthetically pleasing. In the most basic sense this can be achieved by simply manually slicing a food item, such as a vegetable item, to create the desired shape or size. Whilst this is suitable for simple shapes and low volume, for more complicated shapes or higher volume applications, manual cutting is not practical.
Devices exist which automate the process of shaping and sizing, for example, vegetables. These devices come in a variety of forms. One such device comprises a grid like cutting implement, the vegetable being forced through the grid with the aid of an attached lever or ram, slicing the vegetable along the gridlines. Other implements mount the vegetable therein and utilize a spinning motion to shear a portion of the outer surface creating a spiral shaped portion of vegetable. There also exists commercial devices comprising a drum into which a plurality of vegetable items are placed, the drum having an opening to a blade and rotating such that portions of the vegetables become exposed to the aperture and the blade and as such are sliced. The shape of the vegetable in this case being determined by the configuration of the aperture and the blade.
What all of the current devices have in common is a limitation on the shape which can be created from the food item. Simply forcing a vegetable through a two dimensional die or grid, or removing generally parallel slices from a food item, limits the variety and complexity of shape that can be produced.
Moreover, many of the available devices create a significant amount of wastage, and suffer from jamming or clogging due to waste portions of food becoming lodged therein.
It is the object of the present invention to provide for the shaping and sizing of foodstuff in a manner which minimizes waste and provides flexibility in terms of the shapes that may be created.

The present teaching will now be described with reference to an exemplary food processing apparatus for the cutting of foodstuff. It will be understood that the exemplary food processing apparatus is provided to assist in an understanding of the present teaching and are not to be construed as limiting in any fashion. Furthermore, elements or components that are described with reference to any one Figure may be interchanged with those of other Figures or other equivalent elements without departing from the spirit of the present teaching.
Referring now to the accompanying drawings, there is illustrated a food processing apparatus for the cutting of foodstuff 10 having a guide arrangement 11. A primary cutter 12 is located at an open first end 13 of the guide arrangement 11. A secondary cutter 14 is located at or about a second end 15 of the guide arrangement 11 distal the first end 13. The guide arrangement 11 guides foodstuff (not shown) cut by the primary cutter 12 towards and into contact with the secondary cutter 14 for further cutting and/or processing by the secondary cutter 14. The primary cutter 12 cuts the foodstuff such that it is sized to pass into a portion of the guide arrangement 11, and such that it is a suitable size and/or shape for further cutting and/or processing by the secondary cutter.
The primary cutter 12 defines a cutting area 16 and is configured to minimize wastage of the foodstuff and/or prevent clogging by aligning all parts of the foodstuff cut within the cutting area 16 with at least a portion of the guide arrangement into which the cut foodstuff passes. As a result, all of the foodstuff cut within the cutting area passes into the guide arrangement 11 and is thereafter processed by the secondary cutter 14, resulting in minimal wastage and preventing cut portions of foodstuff clogging any portion of the apparatus 10.
The guide arrangement 11 has a plurality of guide tubes 17, each guide tube 17 having a portion 18 of the primary cutter 12 located at an open first end 13, the portion 18 of the primary cutter 12 defining an opening for allowing passage of cut foodstuff into the open end 13 of the guide tubes 17.
A portion 18 of the primary cutter 12 is aligned with and projects from the periphery of the first end 13 of each guide tube 17. As each guide tube 17 has a portion 18 of primary cutter 12 aligned around its periphery, any foodstuff forced towards the guide tube 17 will be cut by the portion 18 of the primary cutter 12 aligned therewith and will resultantly pass into the guide tube 17. The primary cutter 12 comprises a tessellated arrangement of cutting members 18, each cutting member forming the portion 18 of the overall primary cutter 12 aligned around each guide tube 17. In a preferred embodiment as shown in the drawings, the primary cutter 12 comprises a tessellated arrangement of hexagonal cutting members 18. It should be noted that a person skilled in art would be aware that a tessellated arrangement could be formed from any shape suitable for tessellation. Moreover, the shapes forming the tessellated arrangement can be uniformly shaped and sized, or of non-uniform shapes and sizes which combine to form a tessellated arrangement, or a combination of some uniform and some non-uniform shapes. The tessellated nature of the primary cutter 12 results in a cutting arrangement providing guide tube apertures 19 aligned with the opening of the guide tubes 17, but having no gaps between these guide tube apertures 19. As foodstuff is forced onto the primary cutter 12, all of the foodstuff is cut and passed into one or more of the guide tubes 17. As no gaps exist between the tessellated arrangement of cutting members 18, wastage and clogging is greatly reduced or eliminated.
Each of the guide tubes 17 comprises a cutting member 18 of the primary cutting means projecting therefrom. Some of the cutting members 18 have at least one shared wall 20 which is shared by at least one adjacent cutting member 18. The cutting members 18 have a cutting end 21 locatable distal the end of the cutting members 18 closest the guide tube 17, the cutting members 18 adjoining at their cutting end 21 to form the shared walls 20 and thus form a tessellated cutting arrangement.
In one embodiment of the invention, as shown in the drawings, the cutting members 18 are formed integrally of a portion 22 of the guide tubes 17. In an alternative embodiment, the cutting members 18 may be attached to the guide tubes 17.
Each guide tube 17 has its own secondary cutter 14, the secondary cutter 14 having a blade arrangement 23 for cutting the foodstuff such that the foodstuff is shaped to a predetermined shape. In the embodiment shown in the drawings, and referring particularly to
The secondary cutter 14 is a rotatable cutter operably mounted within a bearing 24, the bearing 24 being configured to permit rotation of the secondary cutter 14. The bearing 24 and secondary cutter 14 are operably mountable within end plates 30. The end plates 30 are located at the second end of the guide tubes 17 and each bearing 24 is mountable within a throughbore 32 formed in an end plate 30, the multiple end plates forming a layered end plate arrangement. The mounting of the bearings 24 forms a staggered or misaligned mounting arrangement within the layered end plate arrangement, as best viewed in
The guide tubes 17 diverge at an angle from their first ends 13 closest the primary cutter 12 towards their second ends 15 closest the secondary cutter. The first ends of the guide tubes 17 adjoin at the cutting end 21 of the primary cutter 12 and the second ends 15 of the guide tubes 17 are separated from each other. The divergence of the guide tubes 17 and resulting separation at their second ends 15 provides sufficient space between the guide tubes 17 at their second ends 15 such that a secondary cutter 14, with associated bearing 24, can be mounted to each guide tube 17. In addition, whilst the separation created by the divergence of the guide tubes 17 permits space for mounting the secondary cutter 14, with associated bearing 24, it also permits the apparatus to maintain a minimal overall size as at least the first end 13 can still have a compact cross-sectional area. In an alternative embodiment not shown in the drawings, the bearing and secondary cutting means may be locatable entirely within the guide tubes.
In the embodiment shown in
The secondary cutters 14 are driven by the foodstuff as the foodstuff is forced through the secondary cutting means. The secondary cutter 14 has a blade arrangement 23 having sweep and/or taper which encourages movement of the foodstuff through the cutting blade by encouraging rotation of the blade arrangement 23 as the foodstuff passes through the cutting blade. Alternatively or in combination, the sweep and/or taper of the blade arrangement 23 may encourage rotation of the foodstuff as the foodstuff passes through the cutting blade. In an alternative embodiment, the secondary cutters 14 are driven by a drive motor (not shown).
The apparatus 10 may be incorporated into a piece of food processing plant or machinery and form a step in a wider cutting and/or processing process.
In use, the foodstuff is forced onto the primary cutter 12 which cuts the foodstuff and transfers each cut section into a guide tube 17. As each portion of the primary cutter 12 is aligned with a guide tube 17 due to the tessellated arrangement of the primary cutter 12, all of the cut foodstuff will be transferred to a guide tube 17. The guide tube 17 guides the cut foodstuff towards and into contact with the secondary cutter 14. The cut foodstuff travels through the rotating secondary cutter 14 which cuts/shapes the foodstuff further to create a predefined shape and size.
A method of cutting a foodstuff comprises forcing the foodstuff through the primary cutter 12 such that the cut foodstuff is sized for passing into the guide tubes 17, encouraging the cut foodstuff to travel along the guide tubes 17 and into contact with a secondary cutter 14 such that the cut foodstuff is further cut and/or processed and/or shaped by the secondary cutter 14.
The invention is not limited to the embodiment(s) described herein but can be amended or modified without departing from the scope of the present invention.
