Dung Beetle Spice Grinder is a wind up mechanical device that is used as an aid to food preparation. It's a substantial piece of apparatus requiring its own stand.
It comes in four main parts: mechanical beetle; circular base with machined groove; heavy metal grinding ball; adjustable spring pressure
The beetle contains a clock-work motor, which enables it push the heavy solid iron ball around on a circular grooved track cut into a marble or granite base. The radial arm attached to the ball allows it exert the necessary downwards pressure needed to fully grind and crush the spices.
The raw seed and spices are sprinkled along the pathway of the groove into which the ball is tightly located. Once activated, the mechanical beetle dutifully pushes the grinding ball around using the exact same relentless action as that of a real dung-beetle.
When sufficient rotations have been completed, and the spices reduced to a suitable degree of fragmentation, the entire device can be tipped up, via a strong hinge, causing its contents to be discharged unto a suitable receiving vessel.
