  • Hygienic conveyor roller
    Patent number: 11795005
    Abstract: A hygienic, cleanable conveyor roller for use in a conveyor includes a segmented hub, a plurality of spokes and a rim for contacting a conveyor belt. The segmented hub comprises a plurality of arcuate segments in different axial planes connected to each other. The conveyor roller is mounted upon and rotatable about a mounting shaft that may axially constrain the roller. During a single revolution of the conveyor roller about the mounting shaft, all surfaces of both the conveyor roller and the mounting shaft are fully exposed, allowing the surfaces to be cleaned in place, without requiring removal of the conveyor roller from the mounting shaft.
