In one embodiment, the present disclosure includes a dispenser vane comprising a flexible outer surface and a plurality of flexible teeth arranged along the length of the outer surface. The flexible outer surface and flexible teeth are radially moveable.

In one embodiment, the present disclosure includes a dispenser vane comprising a flexible outer surface and a plurality of flexible teeth arranged along the length of the outer surface. The flexible outer surface and flexible teeth are radially moveable.

In one embodiment, the present disclosure includes a solid dispenser including dispensing vanes coupled rotationally about respective parallel horizontal axes. The two dispensing vanes including a surface at a radial distance from the corresponding parallel horizontal axis with teeth arranged on and projecting from the surface. The surfaces of the dispensing vanes may be in contact between the parallel horizontal axes and are flexible in radial directions of the dispensing vanes. In one example embodiment, the dispensing vanes are configured to rotate in opposing directions about the respective parallel horizontal axes to selectively dispense ingredients from a hopper.
