Abstract

A dispensing system comprises a main base with a hopper insertion hole. An upper base, fixed above the main base by spacers, comprises a stirrer insertion hole. A lower base, below the main base, has a hopper insertion hole with an aperture larger than a diameter of a hopper, and is coupled to the main base by a guide. A rotatable hopper, disposed in the insertion hole of the main base, comprises a bottom surface with metering holes. A stirrer, inside the hopper and fixed to the upper base, feeds material into the metering holes. A gate, on a bottom surface of the lower base, comprises a bottom surface with a dispensing hole. The gate diameter is greater than the hopper. A gate spring, between the bottom of the main base and an upper surface of the lower base, is mounted parallel to a sliding motion of the lower base. A vibration device agitates the assembly on the main base.
