A dispensing apparatus for particulate matter which distributes the particulate matter, at substantially the same rate, uniformly across a given area of a vessel and comprises a particle container having an opening at one end for receiving particulate material into an upwardly directed end and an outlet end at an opposite end for flowing particulate material. A rotor having multiple elongated, hollow arms, an opening at one end for receiving particulate material from the particle container, the multiple arms each having at least one aperture located in a lower portion thereof for discharging particulate material, wherein the rotor is rotatably positioned below and adjacent to the outlet end of the particle container to permit the flow of particulate material from the particle container to the rotor. A baffle plate having multiple elongated leaves, rotatably positioned around a vertical central axis of the rotor and having dimensions capable of reducing the flow of particulate material from the rotor apertures is located in close proximity to each of the apertures of the rotor. A fastening member is provided on the rotor for releasably fastening the baffle plate to the rotor. A rotating member is also provided for rotating the rotor in communication with the particle container in order to evenly distribute particulate matter on a bed below.
