Abstract: An electric hand-held dosing device has an ergonomically shaped handle with an electrical switch. A spring-loaded cap on the handle communicates with an internal hopper. A rotating grater blade is located in the hopper. The grater blade is connected to and rotated by a shaft powered by the power unit. The spring-loaded cap opens to allow for the insertion of a pill or tablet into the hopper. The spring-loading action of the door retains the pill within the hopper and forces the pill against the rotating grater blade. The pill particles exit through an outlet in the hopper. An impeller is mounted on the shaft and distributes the particles or mixes them with a carrier. In this manner, one hand operation of the dosing device is effected.
