Abstract
An apparatus for dispensing granulated powder, such as a fine sugar or sweetener, which uses an auger driven by a gear motor. The gear motor is controlled by a control unit on the front of the dispenser, allowing a user to select the quantity of powder to be dispensed. The apparatus comprises at least one, preferably two dispensing assemblies within the chassis, each comprising a storage bin for the powder, an inclined base, an auger member abutting the base of the storage bin and a dispensing chute. The base of the storage bin is inclined positively toward to the orifice of the dispensing chute, thereby ensuring that the powder is dispensed at a constant rate with minimized dribbling.
