BACKGROUND OF INVENTION 
       [0001]    1. Field of Invention 
         [0002]    This invention relates generally to dicing or shredding food products and, more particularly, to blades for dicing or shredding meat products. 
         [0003]    2. Background Art 
         [0004]    Shortcomings in various existing equipment utilized for shredding food products, particularly meat products have been found and there are no commercially available equipment designs available for resolving the problems. When reviewing of the mechanical action of the machine, particularly the engagement of the cutting or shredding blades or knives with the meat product, the shortcomings are revealed. The engagement or cutting action of the commercially available tooling for the machine does not result in a product that appears to have been made by hand. It is desired in the industry for pizza toppings, pulled whole muscle meat products and other meat products. There doesn&#39;t appear to be an alternative tooling available in commerce that could be used to produce an item that met the customer design criteria, provide the desired pulling action and consistently produce product. 
       BRIEF SUMMARY OF INVENTION 
       [0005]    One embodiment of the invention is a circular blade shredding device to produce a consistent separated, pulled, and/or shredded food product from food items including but not limited to vegetables, fruits, cheeses, cooked meat items as well as a more consistent sized crumble with precooked sausage based items. One embodiment can include a 16 point star shape with angled head or teeth to allow for separating, shredding and/or pulling of a consistent sized product. The blade provides an improved piece sizing in the product while maintaining the natural look desired from the product. Another embodiment includes an additional version with an  8  point shape and modified teeth. 
         [0006]    One embodiment of the invention includes an angle cut of the star and spacing or greater pitch to allow for a more consistent separation, shred or pull from the product being separated, diced/shredded, or pulled and better control of the finished pieces. The bent star point solution improves the engagement, severing and pulling or shredding action. The device can be used on whole muscle smoked meats to create a hand-pulled-like consistent product and improved results can be seen in the resulting product. Consistent improved pulled sausage (having a hand-pinch like pull) or whole muscle (e.g. pulled pork) that was previously commercially unavailable from equipment manufactures can now be provided. 
         [0007]    The engagement and separation action or interaction between the blade and the whole product being separated can vary depending on the speed of the blade, the angle of the points and the width of the blade. Also if adjacent blades are used in a side-to-side relationship then the spacing between adjacent blades and the side-to-side alignment of adjacent star points and their relative speeds can also vary the interaction. The texture, density, firmness, consistency and other aspects of the food product can also vary the interaction. For example, a whole pork meat cut having fibrous muscle tissue will respond to and interact with the blade differently than a cheese product and each of these will respond differently than a vegetable product or any other food product that differs in texture, density, firmness, consistency, pliability or any other characteristic difference. Previous star attachment cutting/shredding blades do not allow for the same separating, severing, shredding and/or pulling action due to the shape of the star points or teeth used. By turning the tips on an angle, a cut and pulling action is achieved, which improves product appearance and consistency. The point make the initial engagement with the product initiating the separation action rather than the rake area of the tooth. The rake area continues the engagement of the separated portion and the rake area has a varying angle that can increase or decrease the aggressiveness of the engagement and the pulling action. 
         [0008]    These and other advantageous features of the present invention will be in part apparent and in part pointed out herein below.

       DETAILED DESCRIPTION OF INVENTION 
       [0054]    According to the embodiment(s) of the present invention, various views are illustrated in  FIG. 1-3  and like reference numerals are being used consistently throughout to refer to like and corresponding parts of the invention for all of the various views and figures of the drawing. Also, please note that the first digit(s) of the reference number for a given item or part of the invention should correspond to the Fig. number in which the item or part is first identified. 
         [0055]    One embodiment of the present invention comprising a circular shredder blade having a forward angled rake and leading point teaches a novel apparatus and method for separating or severing away portions of a food product. For example, one embodiment of the invention can be utilized for shredding a meat product. 
         [0056]    The details of the invention and various embodiments can be better understood by referring to the figures of the drawing. Referring to  FIG. 1 , an illustration of a shredding configuration is shown. The Shredder Assembly  100  illustrated in  FIG. 1  is representative of a typical cutter for a food product, particularly a meat shredder or meat dicer configuration. Although, this or a similar configurations can be used for other food products including but not limited to cheeses and vegetables. However the configuration can vary without departing from the scope of the invention.  FIG. 1  illustrates a product such as a Meat Product  102  being fed through a set of Feed Rollers  104  and being pulled through the Feed Rollers by a Feed Disc  106  having teeth which engage the product thereby pulling the product through the Feed Rollers and urging the product toward the Shredder Blade  110 . The term “shredder blade” used herein is utilized representatively to describe a blade that is not only its scope to be used to shred, but to more generally to separate or sever portions of the food product. Further, the term “shredding” or “shred” or “shreds” is also used herein representatively to include any separating action including severing away and pulling away. The Shredder Blade  110  pulls and separates or shreds meat from the meat product thereby forming a Shredded Meat Product  108  or other food product depending on the application. The rotational direction of the Feed Rollers and the Shredder Blade are indicated by the directional arrows. This configuration can be used to process beef and pork cuts as well as other meat cuts to create a pulled or shredded product. This or a similar configuration can also be used to separate away portions of a vegetable product. The configuration can also be used to process ground meat products such sausage and other ground meat products. 
         [0057]    Referring to  FIG. 2  there is another illustration of a shredding configuration.  FIG. 2  illustrates another embodiment of a Shredder Assembly  200  including essentially the same components including the Feed Rollers  204  and the Feed Disc  206 , which urge the food product toward an engagement with the Shredder Blade  210 . The Shredder Blade again engages the meat product or other food product and shreds or separates sections of the meat away from the meat product thereby creating a Shredded Meat Product  208 . Again, “shredded meat product”, is used to representatively include separated food product. This embodiment illustrates a different blade configuration where the shredder blade has essentially the same diameter, however includes a greater number of teeth thereby reducing the spacing or pitch between the teeth. 
         [0058]    Referring to  FIG. 3A , there is an illustration of a shredding blade.  FIG. 3A  illustrates one embodiment of the Shredder Blade  110 . This Shredder Blade embodiment includes a smaller number of teeth as compared to the other embodiment. The blade has a generally circular or disc-like profile in configuration having a certain width or plate thickness. The blade has a plurality of Blade Teeth  302 , which are angled forward (positive rake) in order to create a engagement and pulling action when engaging the meat product. One embodiment of the blade could be a roller type blade having a similar profile but with a greater width or thickness. The Blade Teeth can include a Front Face having a Rake  311 . The Forward Face of the Tooth  311  having a Rake can be separated into two portions including an Upper Front Face of the Tooth having an Upper Rake  324  of the Tooth  310  and a Lower Front Face of the Tooth having a Rake  326 . The Upper Front Face of the Tooth can have a forward angled Rake (positive rake) or angle that extends over Gullet  314 . The Lower Front Face of the Tooth can have a Rake or angle that has angled backward (negative rake) with respect to the Gullet thereby creating a multi-angled rake or multi-angled Front Face of the Tooth. 
         [0059]    The Gullet  314  between the teeth of the blade can have a facing surface with a convex arc consistent with the circular shape of the overall blade. The positive upper rake  324  with respect to an intersecting radial projection can have a positive angle between 5 to 35 degrees. The negative lower rake  326  with respect to a respective intersecting radial projection can have a negative angle between 5 to 35 degrees. The positive angles  320  and  322  respectively, of the upper  306  and lower  308  trailing faces with respect to their respective intersecting radial projections is between approximately 10° to 70°. 
         [0060]    The blade teeth can also have a Trailing Edge  307  that is also multi-angled having an Upper Trailing Edge with a forward angle and a Lower Trailing Edge with a forward angle where the Upper Trialing Edge had a greater forward angle. The multi-angled Front Face of the Tooth having a combination of an Upper Forward Facing angle and a Lower Rearward facing angle creates a forward face that engages the meat product to thereby create a pulling action against the meat product thereby shredded in a manner similar to that of a hand shredding operation. The multi-angled Forward Face provides a greater surface of engagement with the meat product over a blade having a simple Rearward or Forward Facing angled surface. The diameter of the Blade Tip is illustrated by item  328  and the diameter gullet to gullet is illustrated by item  330 . The Angles  322 ,  320 ,  324  and  326  illustrate the Multi-angled configuration of the Forward Face of the Tooth and the Drilling Edge of the Tooth. 
         [0061]    Each of the plurality of spaced apart teeth have a positively facing tip  304  extending positively beyond any point of the respective rake such that the positively facing tip will engage and pull a product prior engagement of the respective rake. The outermost diameter tip to opposing tip is between approximately 6 to 7 inches and the pitch of the plurality of spaced apart teeth is approximately 1 to 3 inches. 
         [0062]    It should be noted that without departing from the scope of the invention the blade including the plurality of spaced apart teeth can be positioned immediately adjacent a plurality of substantially identical blades and their respective spaced apart teeth and mounted to rotate about a common axially aligned hub. The blades can rotate synchronously, asynchronously or with a delay or stagger. The adjacent blade teeth of adjacent side-to-side blades can be aligned laterally and rotate in unison or the blade teeth can be staggered or off set such that adjacent blades do not impact the product at the same time. 
         [0063]    Referring to  FIG. 3B , there is another illustration of a shredding blade.  FIG. 3B  illustrates the Shredder Blade  210  having a greater number of Blade Teeth  352  however where the Front Face of the Tooth  361  and the Upper Front Face of the Tooth  360  and the Lower Front Face of the Tooth  362  are similar to that shown in  FIG. 3A . Further, the Trailing Edge  357  and the Upper and Lower Trailing Edges  356  and  358  respectively are also similar to that shown in  FIG. 3A . However, given the greater number of teeth the Gullet Area  364  is smaller or shorter and having a concave surface such that the distance between the teeth or the pitch is smaller. This shorter Gullet or shorter pitch will result in a different sized meat product thereby creating a finer shredded product than the blade shown in  FIG. 3A . 
         [0064]    One embodiment for the blade for shredding includes a blade having a generally circular profile with a generally circular periphery and a width. The blade can have a plurality of spaced apart teeth attached to the blade about the periphery where a pitch of the teeth defines a gulley between teeth and said plurality of teeth extending outward from the periphery and each of the plurality of spaced apart teeth having a front face of , where the front face has a multi angled rake including a positive upper rake and a lower negative rake. The distance gulley to gulley can be less than the length of the gulley or the distance gulley to gulley can be greater than the length of the gulley to thereby generate a finer shred. 
         [0065]      FIG. 3A  reflects a blade having the plurality of spaced apart teeth including eight equally spaced teeth.  FIG. 3B  illustrates the plurality of spaced apart teeth including sixteen equally spaced teeth. As shown in  FIG. 3A , the gulley can have an outward facing surface that has a generally convex arcuate contour consistent with the generally circular profile of the blade. As shown in  FIG. 3B  the gulley can have an outward facing surface having a generally concave arcuate contour. Each of the plurality of spaced apart teeth can have a positively facing tip extending positively beyond any point of the respective rake such that the positively facing tip engages and pulls a product prior engagement of the respective rake. This configuration can be used to process various products including but not limited to beef and pork cuts as well as other meat cuts to create a pulled or shredded product. This configuration or similar configuration can also be used for other food products including but not limited to ground meat products, vegetables and other products. For example, this configuration can also be used to process ground meat products such as sausage and other ground meat products. For another example, a pulled pork product can be produced. Also, Italian sausage pizza crumbles can be manufactured from a ground sausage product. 
         [0066]    With a pre-cooked ground sausage product, the sausage can be feed into a blade where the positive angle with respect to an intersecting radial projection of the positive upper rake is between approximately positive 5° to 35°; where the negative angle with respect to an intersecting radial projection of the negative lower rake is between approximately negative 5° to 35°; where the positive angle of the upper and lower trailing faces with respect to their respective intersecting radial projections is between approximately 10° to 70°; where each of the plurality of spaced apart teeth have a positively facing tip extending positively beyond any point of the respective rake such that the positively facing tip engages and pulls a product prior engagement of the respective rake; where the outermost diameter tip to opposing tip is between approximately 6 to 7 inches and the pitch of the plurality of spaced apart teeth is approximately 1 to 3 inches; and where the blade including the plurality of spaced apart teeth is positioned immediately adjacent a plurality of substantially identical blades and their respective spaced apart teeth and mounted to rotate about a common axially aligned hub. 
         [0067]    Further, the blade including the plurality of spaced apart teeth can be positioned immediately adjacent a plurality of substantially identical blades and their respective spaced apart teeth and mounted to rotate about a common axially aligned hub as illustrated in  FIG. 1 . 
         [0068]    The various shredder blade and shredder assembly examples shown above illustrate a method and apparatus for shredding a meat product. A user of the present invention may choose any of the above embodiments, or an equivalent thereof, depending upon the desired application. In this regard, it is recognized that various forms of the subject shredder blade and assembly could be utilized without departing from the spirit and scope of the present invention. 
         [0069]    As is evident from the foregoing description, certain aspects of the present invention are not limited by the particular details of the examples illustrated herein, and it is therefore contemplated that other modifications and applications, or equivalents thereof, will occur to those skilled in the art. It is accordingly intended that the claims shall cover all such modifications and applications that do not depart from the sprit and scope of the present invention. 
         [0070]    Other aspects, objects and advantages of the present invention can be obtained from a study of the drawings, the disclosure and the appended claims.
