Referring to
The machine is characterized by having bars (both attached to a rotating member 102 and to the fixed housing 112 with potential different shapes; circular/cylindrical bars, triangular bars or square bars located in the periphery of a central component 102 placed on a central axis so each bar line formed along the periphery of the said central axis may have two, three, four, five, six, seven or eight bars 104 that pass near the fixed bars 106 as the central component 102 rotates through the action of a lever/handle 114/116 actuated by the operator's arm/hand, who grabs the handle 116 which transmits the force through the lever 116 to the central rod 110 connecting the lever connected to the rotating component 102 which supports the housing/chassis 108 between the slots 112.
This central component 102 is placed along the central axis whose shaft 110 rotates the Bars 104, 106 pass each other. The bars 104 are located equidistant and in a row with the area of rotation and are further interspaced with the permanently fixed (i.e. Affixed) bars 106 and further may also be of different shapes; as bars with circular (cylindrical), triangular or square cross sections and equidistant to the rotating bars 104 so that they cross the fixed bars 106, effecting tearing and/or shredding of the meat 304 within the tray 302 placed around the hopper 306.
The meat may be manually fed through the upper part of the hopper 306 (or through the openings 802/804) where it is shredded/torn. As the meat pieces 304 are processed by contacting rotating bars 104 against the fixed bars 106 within the housing/chassis 108 the product coarseness is controlled by the different thickness of said bars 104/106, which depends on the adjustable and parallel space/distance between the rotating bars 104 and the affixed ones 106. The central component 102 axis is anchored to the housing 108 through screws 704.

In many instances, there is a need for a powered unit capable of performing the shredding of the meat. Referring to
In one exemplary embodiment of such a unit 800, the hopper forms a funnel that leads the material into the shredding area 706 and has one or more removable protection cover 802 (both along the top and/or sides). This may be attached to the mechanical housing 902 covering the motor 702, and creating a base. In one embodiment this cover 802 may be flipped open, in others it may be snapped, covered, slid to the side or similarly placed in a secure fashion. The ability to remove/flip it may be desired for cleaning and other sanitary reasons.
In one embodiment, one or more of the safety covers are equipped with electrical sensors so that the unit grinding motor 702 may not be engaged without the covers 802 being in the proper position. The cover 802 has an opening 804 through which the meat to be shredded is fed onto the shredder bars 104, 106. It is critical that the opening 804 be significantly smaller than a human hand (to prevent accidental insertion into the shredding area and/or the funnel. Making the diameter from 5 to 8 cm is recommended. Looking at the back view 900, we see the motor housing 902, which may completely replace the handle assembly 114, 116 or be connected to the motor shaft.
The motor On/Off switch 904 may act as an emergency shutoff, or a separate push button 906 unit may be placed within the unit. In one embodiment, this is placed over the motor housing and/or on the side. In this fashion, the operator my reach said emergency stop with their free hand.
When looking at the unit from the side, we see that there may be more than one opening 804. In one embodiment, a second side feeding opening 1006 may be added to one or more of the side panels 1002, 1004. In addition, these may also be transparent, to ensure that the operator can see the amount of material still to be shredded. Finally, the front view 1100 of the unit allows us to appreciate the space available for a container in which to receive the shredded product.
