ABSTRACT:
A product size grading system comprises a roller bed having a plurality of rotary shafts wherein each shaft supports product sizing roller members. A motorized transmission is coupled to the plurality of rotary shafts and drives the rotary shafts in a uniform direction wherein each shaft in the roller bed rotates at a different speed. The speeds of the rotary shafts become progressively faster from the input end of the roller bed to its output end. The roller members comprise alternating conveyor disks and nubbin rollers threaded onto each of the rotary shafts. The nubbin rollers are relatively thick disks having a substantially polygonal cross section with flexible nubbins or vanes projecting radially outwardly therefrom. Each nubbin roller is sandwiched by a pair of thin conveyor disks which are also generally polygonal in shape, but have rounded crown portions between their flat portions. The combination of the nubbin rollers and the conveyor disks form product sizing pockets. Undersized product falls into these pockets and is dropped below the roller bed.
