A gravity-fed, manually-operable dispenser for sugar, creamer and other particles and granules is comprised of a particulate reservoir affixed to a dispensing base by engagement tabs and slots. The tabs and slots allow the dispenser to be easily disassembled for maintenance and cleaning. The base encloses a substantially cylindrical rotating measuring/dispensing vane that has several hollow apertures into which particulates flow from the reservoir. The vane rides on a smooth, flat surface that seals or closes off the apertures. An opening in the flat surface of the dispensing base allows particulates in a full aperture to fall through and out of the base. A soft gasket over surfaces of the vane that would otherwise make direct contact with the base portion prevent the vane from becoming lodged in place by crystalline material.
