  • Publication number: 20230115652
    Abstract: The invention relates to a device for crumbling root crops into substantially equal sized pieces and homogenizing the flow of crumbled pieces for analysis. The device can have a crumbling device with a main frame and at least one crumbling shaft rotatably supported in the main frame. The crumbling shaft can have a plurality of curved hooks for interlaced movement with recesses in at least one non-rotating cutting rake and at least one cleaning rake. A transport device can move the stream of crumbled root crops from the crumbling device where the stream can be leveled with a leveling rake and compressed into a substantially flat and uniform flow with a roller. The roller can have one or more scrapers positioned to clean the roller surface of residual root crop product and distribute the cleaned material in locations away from the stream to be analyzed to avoid contamination.
