Star Wheel Conical Plate Hygienic Design

The patent applies curvature by replacing horizontal surfaces with a conical surface that slopes downward toward the center. The star wheel features a conical plate with a downward slope that directs liquid and contaminants toward the center outlet, eliminating flat surfaces where dirt could accumulate. This curved geometry maintains ease of manufacture through standard conical forming processes while significantly improving cleanability.

The patent combines multiple attachment functions into a single central conical plate that integrates the mounting surface, anti-rotation feature, and liquid sealing into one unified component. This single plate is secured by one central screw, eliminating the need for multiple separate attachment components while maintaining secure connection through the integrated design features including the conical shape for positioning and the metal seal for liquid tightness.

The patent segments the attachment system into a modular conical plate assembly that can be manufactured as a single integrated component or pre-assembled unit. This segmentation allows the complex conical plate with integrated features to be manufactured separately and then quickly installed as one unit, reducing overall assembly time while maintaining ease of manufacture through standardized segments.

The patent extracts and removes horizontal surfaces and corners from the star wheel design, retaining only the essential structural elements needed for support. The design uses a minimal conical plate structure with downward slope that provides adequate structural support while eliminating surfaces where liquid could adhere. The spokes and support elements are configured to minimize surface area while maintaining mechanical strength.
