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 figure number in which the item or part is first identified . one embodiment of the present invention comprising a grinder , conveyor , and cutter teaches a novel apparatus and method for segregating sparse lean product based on percent fat content . sparse lean product or trim can be accumulated trim in an auger / grinder . the grinder can be equipped with rotating knife or cutting plate to pre - size the product . the auger / grinder &# 39 ; s end plate can be adapted with an adapter to output the ground product horizontally . a conveyance system can be communicably connected to the output of the grinder ( an example of a conveyance system can be a plurality of tubes ) for conveying the ground product to an x - ray station disposed after the output of the auger / grinder . an x - ray or near infra - red ( nir ) system can be used to detect the combined fat analysis ( fa ) by every predefined scan length of the tube cross section . the x - ray or nir can provide an input to a controller system that can at the appropriate time activate the solenoid valve push mechanism to open / close a knife gate . the cut product will be dropped onto a conveyor that transports the product to a combo or other process . the x - ray or nir software along with the controller can keep the aggregate fa of each of the products / conveyors ( output streams ). each of the output streams can further be combined to get a desired out fat % combo the details of the invention and various embodiments can be better understood by referring to the figures of the drawing . referring to fig1 , a top view of the lean recovery system 100 is shown . the top view shows the end to end process from the input of the sparse lean product to the recovered lean product segments that have been sorted for further processing . the sparse lean product or meat trimmings can be input into the system by the sparse lean feed conveyor 102 . the sparse lean product or trimmings are conveyed from the input end of the conveyor to the output end of the conveyor where it is dropped into a reducer 101 whereby the sparse lean product can be diced or reduced into smaller pieces . the reducer 101 is illustrated in this figure as a grinder system including a grinder hopper 103 which channels the sparse lean product into the grinder 104 . the grinder can be equipped with a rotating knife or auger type mechanism to pre - size the product and the grinder can have a pre - sizer end plate that is modified to output the minced or diced product horizontally . the grinder 104 can have a horizontal adaptor output 105 which can channel the minced product into a conduit 106 which in turn channels the product through tubing 108 . the tubing 108 can extend through a scanner 110 having an internal scanner position 109 whereby the scanner can scan incremental lengths of the product traveling through the tubing passing through the scanner position . the scanner 110 can have a scanner control interface 111 whereby a user can provide inputs into the scanner as well as monitor various operational parameters . the scanner can be adapted to scan the product along incremental predetermined lengths to thereby scan incremental segments of the ground sparse lean product traveling through the conveyance channel illustrated in this figure as tubing . the incremental predetermined lengths of ground sparse lean product can be scanned as the product passes through the scanned position . the scanner can be an x - ray type scanner or alternatively a near infrared type scanner which can be adapted to scan the product traveling through the conveyance channel and take the scanned data and analyze it to determine the fat content . the scanner can be adapted to scan incremental lengths and determine the fat content contained within those incremental lengths in order to more accurately account for changes in fat content of the ground sparse lean product traveling through the conveyance channel . one embodiment of the present invention can include a scanner that scans over incremental predetermined lengths where the lengths are from about approximately 4 millimeters to about approximately 10 millimeters in length . in the non - invasive lean recovery system 100 can also include a controller 126 that communicates the width of the scanner 110 for exchange of control parameters . the controller 126 can also communication and control the conveyor 102 , the reducer 101 , the scanner 110 , the various product flow sensors 124 , the cutters 112 , the product conveyors 118 , the reject conveyors 120 , and the various rejection mechanisms 122 . once the ground sparse lean product has traveled through the portion of a conveyance channel or tubing then extends through the scanner the ground sparse lean product will continue to travel through the conveyance channel through the reject portion of the tubing or conveyance channel 114 . the reject portion of the conveyance channel 114 will extend to cutters 112 which will incrementally cut away segments of the ground sparse lean product where the incremental segments are cut at lengths consistent with the predetermined length of the scan . therefore each ground sparse lean product segment that is cut away will have a corresponding percent fat content that has been calculated by the scanner . each ground sparse lean product segment that has been cut away will be transferred to a reject conveyor 120 and as the ground sparse lean product segment travels along the reject conveyor the product segment can be selectively sorted based on its percent fat content . this can be accomplished by utilizing ejection mechanisms 122 spaced incrementally along the length of the reject conveyor 120 . the ejection mechanism can laterally push this product segment off of the reject conveyor 120 down a chute that channels the segment to an appropriate product conveyor that corresponds to a predefined percent of fat content percentage range . therefore , for each product segment that is cut away a fat content for that segment has been determined by the scanner . the fat content determined can fall within various predetermined percent ranges and the product segments can be sorted in accordance to those predetermined percentage ranges . a plurality of product conveyors can be utilized whereby each of the plurality of conveyors can correspond to a given percentage range . the product segment can be in turn ejected at the appropriate time to fall on the appropriate corresponding product conveyor having a predefined percentage range for which the fat content of the product segment falls . in fig1 the reject conveyor 120 and the product conveyor 118 are illustrated as a plurality of endless belt conveyors that travel in parallel . however , other conveyance means can be utilized . the injection mechanism is shown in this figure as a plurality of air nozzles that are incrementally spaced along a length of a reject conveyor whereby the air nozzles are designed and controlled to emit an air jet pulse to laterally push a product segment off the reject conveyor into the appropriate chute channeling the product segment to the appropriate product conveyor . referring to fig2 , a side view of the lean recovery system 100 is shown . again an end to end view of the lean recovery system is shown . as illustrated previously the sparse lean feed conveyor 102 is positioned to convey the sparse lean product or trimmings to the reducer 101 . the reducer 101 is designed to flow the product through the horizontal adaptor output plate 105 and into the conduit 106 and further into a plurality of conveyance channels 108 . product flow sensors can be positioned along the conveyance channel in order to determine the product flow at various positions along the channel . the product flow sensors are shown in fig2 as items 202 , 124 , and 204 . this side view reveals the scanner control interface 111 whereby a use can provide certain inputs and view certain operational parameters of the scanner . the scanner can have a stack light 206 than can provide an indication of the operation mode of the scanner . the controller 126 is again show adjacent to the scanner . the reject tubing 114 is shown extending into a cutter 112 which is positioned above the product end reject conveyors . referring to fig3 , a front view of the lean recovery system 100 is shown . again the scanner 110 and the controller 126 are shown adjacent with a communication conduit connecting the two panels . this front view reveals the scanner chamber 304 in which there is a scan position 109 and it is at this position where the scanner scans the product over a predetermined length . this view also shows the view of the cutters 112 having a conduit 302 out of which the product segments exit to thereby fall onto the reject conveyor 120 . the reject conveyor can be designed to transfer any rejected product not meeting one of the predetermined percentage fat content ranges onto a take away conveyor ( not shown ) for further processing . any product selectively ejected based on falling within one of the predetermined ranges full percent fat content will be ejected to one of the plurality of product conveyors 118 . referring to fig4 , a perspective view of the lean recovery system is shown . the sparse lean feed conveyor 102 is shown as an endless belt conveyor that drops the sparse lean product onto hopper deflector plates 401 , 402 , 403 , 404 , and 405 . the deflector plates channel the product into the reducer . a communication conduit 406 is shown in this view that can be connected to the controller 126 ( not shown in this view ). as previously indicated the cutter 112 can cut the ground sparse lean product into product segments having a length that corresponds to the predetermined scan length and the product segments can fall onto the reject conveyor where the product segments can be selectively ejected down a chute 408 which will direct the product segment to fall on the selected product conveyor having a percentage fat content range that corresponds to the fat content of the product segment determined by the scanner . referring to fig5 , a perspective view of the cutter and reject tubing and product conveyor channels are shown interfacing with the grinder . in this view the grinder is shown having a grinder input end 502 through which the sparse lean product can be inserted and subsequently dropped and directed by the hopper deflector plates . as previously indicated products flow sensors 124 , 202 , and 204 can be utilized to determine the product flow along various positions of the product conveyor channels . therefore , the sparse lean product is input through the grinder input end 502 and is minced or diced into a ground sparse lean product that travels through the conveyance channels and is ultimately cut by the cutters 112 and the product segments are output through the cutter conduits 302 . referring to fig6 , a perspective view of the cutter and reject tubing 114 is shown . again the cutters 112 will cut away product segments which will in turn fall onto the reject conveyors 120 . as the product segments travel along the reject conveyors 120 the product segments can be ejected laterally off of the reject conveyor by an ejection mechanism 122 which in this case is shown as a air nozzle that is controlled by the controller to selectively emit an air jet puff to laterally push the product segment laterally off of the reject conveyor down a chute 408 which will channel it to the appropriate product conveyor 118 . each of the cutters and the conveyors can be communicably linked to the controller 126 such that the controller can provide control parameters or inputs to thereby control the operation of the various components . further the product flow sensors 204 and the other product flow sensors as mentioned previously , can be communicably linked with the controller to provide product flow data which cab be utilized to control the various components of the system . referring to fig7 , an illustration of the controller station as it is shown . the controller station 126 is shown having a display 702 whereby user can view various inputs and control parameters and the various subcomponent system operations such as the operation of the grinder as well as viewing product flow data provided by the product flow sensors . the controller 126 can also have an input device 704 that allows the user to input certain control parameters or control functions for controlling the operation of the overall system . fig8 is an illustration of the system and method is shown . with this illustration that trim is processed in order to pump or push the product along conveyance channels that can then be scanned by the appropriate scanner as the product travels through a scan position once the product is scanned it can be sorted to one of a plurality of product channels that are segregated by predefined percent ranges that are representative of the percent content desired for the conveyance pan et . al . referring to fig9 - 11 , another system 900 embodiment having similar components as the above described embodiments is illustrated ,
