DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
A cheese shredding apparatus (10) has a support table top (14) having a plurality of support legs (12).
The table top (14) includes a rolling platform (16) that uses 2 pairs of beveled wheels (18). A partitioned hopper (20), so named because it has a partition (21), contains blocks of cheese (not shown) to be chopped. A pair of cutting grids (22) located at opposite ends of a cutting block (24) and a pair of push cube modules (26) cooperate in the process of chopping the cheese and then pushing it out of the cutting grids (22). The cutting block (24) has one set of blades (25) at opposite ends a top (27) and two sides (29).
A motor (28) powers the rolling platform (16) by way of a cam (30) which converts a rotational motion from the motor (28) into a linear motion which actuates the back and forth motion of the rolling platform (16).
As can be seen in FIG. 5a, a block of cheese (31) located inside a first partition (20′) has dropped down onto the rolling platform (16) so that it is in line with the cutting grid (22), as the cutting grid (22) moves, in this case to the left, as seen in FIG. 5b, a piece of the cheese (31) in the first partition (20′) is being cut and the cut part drops down into a container (not shown) or a conveyor belt (not shown). The cheese (31) in partition (20′), as seen in FIG. 5b now rests atop the cutting block (24) while the cheese (31) in a second partition (20′′) now drops onto the rolling platform (16), ready to be cut by the return of the cutting block (24) towards the right.
The beveled wheels (18) roll on a pair of tracks (32) which are held within the table top frame (34).
A problem of the cheese shredders and cutters of the prior art is that they tend to create a black smudge on the cheese. The black color comes from a chemical reaction between the lactoserum in the cheese and the stainless steel blade. This phenomenon occurs when there is a strong pressure between the cheese and the blade, which extracts the lactoserum from the cheese. In order to avoid that, this present invention makes use of its beveled wheels (18), cutting block (24), push cube modules (26) and its rolling platform (16) which cooperate together to reduce the pressure applied to the cheese at the moment it makes contact with the stainless steel of the cutting block (24).
The beveled wheels (18) are not subject to as much wear as ordinary wheels and as such, maintain a very precise and accurate tracking motion of the rolling platform (16) as they move back and forth as guided by the tracks (32). This ensures very precise and accurate alignment with the cutting block (24) and push cube modules (26). The fact that the adjustments are precise means that no cheese fragment will escape the area of the cutting (24) and push cube modules (26) so as to wander onto the tracks (32) and interfere with the beveled wheels (18). This is a problem that is often encountered in cheese shredders of the prior art and which makes them hard to clean and unhygienic, amongst other drawbacks.
The cheese shredding apparatus has a method of operation consisting in the steps of: a first block of cheese located inside a first partition drops onto the rolling platform so that it is in line with the cutting grid. As the cutting grid moves, in one direction a piece of the first block of cheese inside the first partition is being cut and the cut part drops down for further processing. As the first block of cheese rests atop the cutting block, a second block of cheese located in a second partition of the hopper drops onto the rolling platform to be cut by the return of the cutting block in an opposite direction.
Other parts are mostly cover plates such as push cube module covers (40, 40′), held by wing nuts (41); motor cover (42); a motor housing top cover (44); and a motor housing rear cover (46). Also, the cheese shredding apparatus (10) has support legs (12) which can optionally have wheels (48).
As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
